Abstract

Provided is a clip easily removable from an object to be fixed. The clip is constructed from two parts that are a first member (1) and a second member (2), the first member having a head section (4) and a shaft section (5), the second member having a flange section (11) and a leg section (12). An opening (13) is formed in the flange section of the second member, and the leg section of the second member is split into two to define a gap (17), communicating with the opening in which the shaft section of the first member is inserted, between each split leg section (16). Radially extending elastic blades (18) are arranged in multiple stages in the vertical direction on the outer peripheral surface of each split leg section. When the shaft section of the first member is pulled out from the gap between each leg section, the shaft section is not present any more in the gap. Removing the first member together with the second member from an object to be fixed by grasping a head section of the first member causes each split leg section to deflect inward in the gap. The clip itself can be easily removed.

Problem to be solved by the present invention

Accordingly, the advantage of using conventional clips is that the crown trim can be secured to the roof side in a single action by selectively utilizing the multi-stage elastic blades to effectively absorb the total plate thickness of the roof trim and roof. However, on the other hand, in the case of removing the clip from the mounting hole to release the fixed state of the top trim and the top cover, it is necessary to pull out the clip strongly while largely bending the multi-stage elastic blade in the opposite direction. Therefore, the use of a tool, such as a slotted screwdriver, is usually unavoidable. When the object to be fixed is made of fragile material, as is the case for crown trims, in particular, the use of tools in the pulling operation must be done with great care. Therefore, there is a disadvantage that the pulling out operation of the clip itself is very troublesome even with the use of a tool.

Advantages of the invention

Accordingly, in the first aspect of the invention according to the present invention, in the case of fixing the object to be fixed, if the rod portion of the first piece is inserted into the space formed between the separated pillar portions of the second piece, And push it into the installation hole of the object to be fixed, so that the separated pillar parts can be prevented from approaching each other. Therefore, in the same manner as conventionally, the object to be fixed can be reliably fixed by virtue of the action of the multi-stage elastic blades provided on the outer peripheral surfaces of the divided pillar portions.

On the other hand, when removing the clip itself from the mounting hole of the fixed object to release the fixed state of the fixed object, if the rod of the first piece is pulled out from the gap between the pillar parts separated by the second piece portion, the stem portion of the first piece is no longer located in the space formed between the spaced-apart strut portions of the second piece. Therefore, if the first piece is taken out from the fixed object together with the second piece while holding the head of the first piece afterwards, the separated pillar portions are largely deflected inwardly through the gap, thereby , the clip itself can be easily removed with light force applied by the operator's fingers, without the need for tools. In addition, since there is virtually no need to bend the multi-stage elastic blades in opposite directions, if the clip is reused after removal, there is less drop in its holding force.

According to the second aspect of the present invention, when the clip is removed from the mounting hole of the object to be fixed, if an attempt is made to pull out the stem portion of the first piece from the pillar portion of the second piece, the The locking protrusion on the shank of the part is inseparably engaged with the engaging shoulder provided on the inner peripheral surface side of the opening of the second part, so that the second part can be removed together with the first part with relatively light force.

In accordance with the third aspect of the present invention, in the case of removing the clip from the mounting hole of the object to be fixed, if an attempt is made to pull out the stem portion of the first piece from the pillar portion of the second piece, the locking protrusion is engaged with the The shoulder engages and the side locking projection abuts against the lower surface of the flange portion of the second member, thereby more reliably preventing the first and second members from being erroneously separated.

In accordance with the fourth aspect of the present invention, if the stem portion of the first member is inserted into the space between the separated pillar portions, the fitting protrusion provided on the stem portion of the first member is aligned with the fitting protrusion provided on the second member. The joining shoulder on the inner peripheral surface side of the opening of the parts is engaged, and thus, there is no possibility of the two parts being separated during shipping and handling. In addition, since the fitting projection is detachably engaged with the engaging shoulder, the first member can be pulled out from the second member without excessive force.

In accordance with the fifth aspect of the present invention, if the stem portion of the first member is inserted into the space between the separated pillar portions of the second member, the stem portion and the separated pillar portions are connected to each other so that They are inseparable from each other. Therefore, if the clip in this state is inserted into the mounting hole of the object to be fixed, even if the lower edge of the separated pillar portion 16 collides with and contacts the edge of the mounting hole, there is no lower end of the separated pillar portion 16. Possibility that the part is folded in reverse and cannot be pressed in.

In accordance with the sixth aspect of the present invention, since the thin-diameter portion is formed in the portion of the stem under the portion where the fitting projection is provided, in the engagement between the dismounting projection and the engaging shoulder, from the second In the case where the first-piece stem portion is pulled out on the two-piece side, the pull-out resistance is particularly reduced at an early stage, thus making the pull-out easy.

In accordance with the seventh aspect of the present invention, since the lower surface of the flange portion of the second member has a groove relationship, it is difficult to separate the pillar portions when the total plate thickness of the fixed object is thin, such as The part near the flange part is deflected inward. However, at this time, since the flange portion of the second member itself is deflected by virtue of the groove, inward deflection of the divided post portions can be facilitated.

In accordance with the eighth aspect of the present invention, since a pair of rib walls are arranged diagonally on the stem portion of the first piece so that the rib walls and the stem portion can form an S-shaped cross section, the walls of the rib walls and the stem portion Thickness can be formed thicker, so that higher rigidity can be achieved. At the same time, in a state where the first piece and the second piece are integrated, the shape of the tip can be formed sharper, so that guideability is also improved. In addition, since the insertion portion of the separated pillar portion engages into the gap between the side surface of the stem portion and the inner surface of the rib wall, the stem portion and the lower end portion of each separated pillar portion are connected so as to be connected to each other. cannot be separated.

According to the ninth aspect of the present invention, since the end edge of the first piece is integrally formed with the opening edge of the flange portion of the second piece by means of the small bridge piece, only by pressing the first piece into the pillar portion of the second piece Cutting off the small bridge pieces at the same time by the head of the head can make the first part and the second part integral, thus making the assembly operation of the two parts quite easy.

In accordance with the tenth aspect of the present invention, due to the relationship that the stem portion of the first piece is connected with the opening edge of the flange portion of the second piece at the four end corners of the end rectangular cross-section thereof by means of the small bridge pieces, it is possible to effectively This prevents the first part from tilting or wobbling relative to the second part, and at the same time allows the small bridge to be cut off with less force, thus making it easier to carry out the assembly operation of the two parts. In addition, by virtue of the presence of the wedge surface, even if chips or the like occur, the shaft portion of the first member can be reliably inserted into the space on the side of the second member.

According to the eleventh aspect of the present invention, since the locking protrusion is provided at the end of the rod having a rectangular cross-sectional shape in the first piece, the locking can be provided at a position as close to the end side of the rod as possible. protruding. Therefore, when the locking projection is brought into engagement with the engaging shoulder on the side of the second part, there is no longer an obstacle in the space formed between the separated leg parts of the second part, so that the separated leg parts Can easily flex inward.

In accordance with the twelfth aspect of the present invention, since the notch is formed at the corner in a diagonal manner on the prismatic stem of the first piece, and the clearance on the side of the second piece is made similar to the cross-sectional shape of the stem When a load is applied in the width direction of the rod portion, the protruding end edge of the rod portion abuts against the edge of the mounting hole of the fixed object, so that deviation can be avoided. Simultaneously, it is possible to avoid the falling of each separated pillar part to the side of the rod part, and it is also possible to avoid the flapping of the separated pillar part against the edge of the mounting hole.

In accordance with the thirteenth aspect of the present invention, since the gap is formed between the head portion of the first piece and the flange portion of the second piece, when trying to pull out the first piece from the gap between the divided pillar portions, When removing the stem of one piece, the head of the first piece can be lifted, making it very easy to access.

Detailed ways

In the present invention, the so-called tree clip is configured to include the first piece and the second piece, and to organically combine the first piece and the second piece. In the case of fixing the object to be fixed, as the first piece is inserted into the side of the second piece, the first piece and the second piece are integrated, and the clip is used in this state. On the other hand, in the case of removing the clip from the mounting hole of the fixed object to release the fixed state of the fixed object, it is only necessary to pull out the first piece from the second piece side by means of the necessary part, so that the second piece The spaced-apart strut portions flex inwardly, thereby enabling simple removal of the first piece together with the second piece from the mounting hole.

first embodiment

Hereinafter, the present invention will be described in detail based on preferred embodiments illustrated in the drawings. Unlike conventional single pieces, the clip according to the first embodiment consists of two parts, comprising a first piece 1 and a second piece 2 . The feature is that the first piece 1 and the second piece 2 are integrally formed by synthetic resin, as shown in FIG. 1 . It should be noted that when integrally formed, the arrangement is arranged in this way. As shown in FIG. , meanwhile, the end of the stem portion 5 (described below) of the first piece 1 is aligned with the edge of the opening 13 (described below) of the second piece 2 . In this state, the first piece 1 is pressed into the second piece 2 while the small bridge piece 3 is being cut off, so that the integrated state of the first piece 1 and the second piece 2 can be achieved very simply.

Accordingly, first, the structure of the first piece 1 is described. As shown in FIGS. 3 and 4 , the first piece 1 includes: a disc-shaped enlarged head 4 , which is sized to be held; and a prismatic stem 5 extending from the lower surface of the enlarged head 4 . For the rod portion 5 described later, notches 5a are formed diagonally at the corners so that the cross-sectional shape has a center line as a boundary line, and the notches 5a are staggered left and right with respect to the width direction. In addition, a pair of rib walls 6 are continuously formed on both sides in the axial direction, each rib wall 6 being T-shaped for engaging into a connection groove 19 of the second member 2 described below. In particular, on the distal end side of the rod portion 5, each rib wall 6 is chamfered into a wedge surface 7, thereby forming only the remainder into a rectangular cross-sectional shape, and the above-mentioned small bridges 3 are connected to the rectangular cross-sectional shape. on the four corners. In addition, on the outer peripheral surface above each small bridge piece 3, a pair of locking protrusions 8 are provided, and the pair of locking protrusions 8 are respectively inseparably engaged with engaging shoulders 15 of the second member 2 described below. It should be noted that, in order to inseparably engage the locking projection 8 and the engagement shoulder 15, the upper surface side of the locking projection 8 is formed as a right-angle joint surface, and the lower surface side thereof is formed as a wedge surface.

In addition, this time, at the base end of the rod portion 5 near the enlarged head 4 side, a pair of fitting protrusions 9 are provided on the outer peripheral surface, and the fitting protrusions 9 are detachably separated from the engaging shoulder 15 of the second member 2 described later. join. In order to detachably engage the fitting protrusion 9 and the engaging shoulder 15, both upper and lower surfaces of the fitting protrusion 9 are formed as wedge surfaces. Furthermore, a structure is currently employed in which the portion of the stem portion 5 below the portion where the fitting protrusion 9 is provided is formed as the thin diameter portion 10 .

Next, the structure of the second member 2 will be described. And, as shown in FIG. 5, the second part 2 includes: a disc-shaped flange part 11, which is smaller than the enlarged head 4 of the first part 1; extend. In the above-mentioned flange portion 11, an opening 13 communicating with a void 17 described below is formed at its center, and, in the lower surface of the flange portion 11, a pair of grooves 14 are formed parallel to the A pair of spaced-apart strut portions 16 extend with the opening 13 located between the grooves 14 . Meanwhile, on the lower side of the opposite inner peripheral surface of the opening 13, engaging shoulders 15 are provided which engage with the locking protrusion 8 and the fitting protrusion 9 of the above-mentioned first piece 1, respectively. It should be noted that the lower surfaces of these engaging shoulders 15 are formed as right-angled engaging surfaces.

In addition, the latter pillar portion 12 is constructed such that the pillar portion 12 is separated into two parts in a left-right symmetrical manner to form a void 17 communicating with the opening 13, and the rod portion 5 of the first piece 1 is inserted into a pair of In the gap 17 between the separated pillar parts 16, and at the side edges of each separated pillar part 16, a pair of protruding parts 16a are arranged in a diagonal manner, and the protruding parts 16a protrude inwardly, And it faces the notch part 5a of the rod part 5. As shown in FIG. Therefore, the void 17 is similar to the cross-sectional shape of the stem portion 5 except for the rib wall 6 . In addition, on the outer peripheral surface of each separated strut portion 16, radially upwardly protruding elastic vanes 18 are provided in a multi-stage manner in the vertical direction, and at the same time, on the inner peripheral surface of the separated strut portion 16, A pair of similarly shaped connection grooves 19 are respectively formed in which the T-shaped rib walls 6 are held.

Accordingly, in the case of fixing the roof trim P1 as a vehicle interior material to the roof P2 as a vehicle body panel using the clip of the above structure, in order to make the integrally formed first member 1 and second member 2 fit together Before becoming one piece, the small bridge 3 is first cut off inside or outside its molding die, and the enlarged head 4 of the first piece 1 is pressed to insert the stem 5 of the first piece 1 into the strut formed in the separation In the space 17 between the parts 16. In this case, since the stem portion 5 of the first member 1 is connected to the edge of the opening 13 of the flange portion 11 of the second member 2 at the four end corners of its end rectangular cross-section, a small The small bridge piece 3 can be cut off by force without causing the first piece 1 to tilt or shake relative to the second piece 2, so that the first piece 1 and the second piece 2 can be assembled easily. In addition, relying on the wedge surface 7 existing at the end of the rod portion 5, even if chips or the like are cut off, the chips or the like can be absorbed by the wedge surface 7, thereby enabling the rod portion 5 of the first member 1 to be reliably fixed. It is inserted into the gap 17 on the side of the second part 2.

In addition, in the state where the first piece 1 and the second piece 2 are integrated, as shown in FIG. The engaging shoulder 15 on the inner peripheral surface engages, and at the same time, keeps the locking projection 8 in pressure contact with the inner peripheral surface of the correspondingly spaced pillar portion 16 at the lower end side. Therefore, during transportation or handling, there is no possibility of detachment of the first part 1 and the second part 2, and each outer peripheral surface of the prismatic rod part 5 and the inner peripheral surface of each separated pillar part 16 Between, the minute gap 20 is continuously formed.

Accordingly, in the state where the first part 1 and the second part 2 are integrated, the clip is indistinguishable from a conventional one-piece clip.

After reaching the state where the first piece 1 and the second piece 2 are integrated, the top decoration P1 is superimposed on the top cover P2 to achieve a state where its mounting holes H1 and H2 are aligned, and the pillar part 12 is pressed into the Mounting holes H1 and H2. Then, in the process of passing the elastic blades 18 provided on the outer peripheral surfaces of the divided pillar portions 16 in a multi-stage manner through the mounting holes H1 and H2, the elastic blades 18 are pressed by the inner peripheral surfaces of the mounting holes H1 and H2. and bent, and, after passing through the rear side of the mounting holes H1 and H2, the elastic blade 18 returns to its original state, thereby preventing the second member 2 from coming out of the mounting holes H1 and H2. As a result, the top trim P1 is fixed on the top cover P2 as shown in FIG. 7 .

In addition, in this case, since the rod portion 5 of the first member 1 is inserted into the space 17 between the separated pillar portions 16, the separated pillar portions 16 are no longer close to each other, thus, unlike the conventional In the same way as the clips, a reliable and stable fixation of both parts P1 and P2 can be achieved. In addition, when the pillar portions 12 of the second member 2 are pressed into the mounting holes H1 and H2, even if the lower end edges of the separated pillar portions 16 abut against and contact the edge of the mounting hole H1, due to the The stem portion 5 is connected to each separated strut portion 16 of the second member 2 and cannot be separated from each other because the corresponding rib wall 6 and the connecting groove 19 are engaged with each other almost the entire length thereof, so there is no separation. There is no possibility that the lower end portion of the pillar portion 16 is folded up and cannot be pressed into the mounting holes H1 and H2. At the same time, lateral offset between the rod portion 5 and the separated pillar portion 16 can also be effectively avoided.

In addition, since the notch portions 5a are formed diagonally at the corners of the prismatic rod portion 5 of the first piece 1, and the protrusions are formed diagonally at the side edges of the separated pillar portions 16 of the second piece 2. 16a so that when a load is applied in the width direction of the rod 5, the opposite protruding end edges of the rod 5 abut the edges of the mounting holes H1 and H2, thereby avoiding deflection. Simultaneously, it is possible to prevent each separated pillar part 16 from falling to the side of the rod part 5, and it is also possible to avoid the knocking sound of the separated pillar part 16 against the edges of the mounting holes H1 and H2.

Reversely remove the clip itself from the mounting holes H1 and H2 to release the fixed state of the top decoration P1 and the top cover P2. From the space 17 between the spaced pillar portions 16 of the second part 2, the stem portion 5 of the first part 1 is pulled out, and the gap 20 (each formed between the stem portion 5 and each separated pillar portion 16) is used. Between), the rod portion 5 of the first piece 1 is gradually pulled out from the gap 17 between the separated pillar portions 16 . At this time, as shown in FIG. 8 , the locking projection 8 is inseparably engaged with the engaging shoulder 15 provided on the inner peripheral surface of the opening 13 . As a result, the strut portions 16 separated in the gap 17 are no longer hindered from approaching each other. Furthermore, since the locking projection 8 is arranged as close as possible to the extreme end side of the rod 5 , as described, there is hardly any hindrance.

It should be noted that the fitting projection 9 provided on the stem 5 of the first piece 1 engages with the engagement shoulder 15 before being pulled out, as described above. However, since the fitting projection 9 is detachably engaged with the engaging shoulder 15, the stem portion 5 of the first member 1 can be pulled out of the gap 17 of the second member 2 without excessive force. At the same time, since the thin diameter portion 10 is formed at the portion below the fitting protrusion 9, the first part 1 is pulled out from the second part 2 side by disengaging the engagement between the fitting protrusion 9 and the engagement shoulder 15. In the case of the stem 5, the pull-out resistance is significantly reduced in the early stages, making pull-out easier.

Accordingly, if the first piece 1 is then removed from the mounting holes H1 and H2 together with the second piece 2 in the locked state while continuing to hold the enlarged head 4 of the first piece 1 tightly, due to the gap 17, the The divided strut portions 16 are largely deflected inwardly. Therefore, even if the multi-stage elastic blades 18 extend obliquely upward, there is actually no need to bend the multi-stage elastic blades 18 in the opposite direction, so that the clip itself can be removed by applying a light force with the operator's fingers without using conventional tools in the way.

In addition, in the first embodiment, since the groove 14 is provided in the lower surface of the flange portion 11 of the second member 2, in the case where the total plate thickness such as the top trim P1 and the top cover P2 is relatively thin, it is difficult to It is difficult for the portion of the divided pillar portion 16 close to the flange portion 11 to flex inwardly. However, at this time, because the flange portion 11 of the second member 2 itself is deflected by the groove 14, the inward deflection of the separated pillar portions 16 can be effectively promoted, thereby, in any case, it is possible to use the Your fingers remove the clips themselves without the use of tools. Therefore, even if the top decoration P1 is formed of a fragile material, the top decoration P1 will not easily be damaged due to no operation.

It should be noted that in the case of reusing the clips once removed from the mounting holes H1 and H2 to fix the top trim P1 and top cover P2, the first piece 1 and the second piece 2 should be aligned as much as possible in advance. one piece, and push it as a whole into mounting holes H1 and H2 as described above. However, if the second piece 2 is first pushed into the mounting holes H1 and H2 alone, and then the rod portion 5 of the first piece 1 is pushed into the gap 17 of the second piece 2, the multi-stage elastic blade can be inserted with a relatively small force. 18 of the second piece 2 strut portion 12 is pushed into the mounting holes H1 and H2.

second embodiment

Next, a clip according to a second embodiment is described. The structure of the clip according to the second embodiment is basically the same as that of the above-mentioned first embodiment, the difference is that: firstly, as shown in Figs. The T-shaped rib wall 6 on the top, and a pair of rib walls 6 are continuously formed in the axial direction in a diagonal manner on the two end faces of the rod portion 5, which together form an S-shape with the prismatic rod portion 5, and on the rib wall A pair of side locking protrusions 21 are provided in a protruding manner at the end edge of 6 . The arrangement is such that when the stem portion 5 of the first piece 1 is to be pulled out from the space 17 between the spaced-apart pillars 16 of the second piece 2, the side locking protrusion 21 is formed in contact with the second piece 2. The grooves 14 in the lower surface of the flange portion 11 are adjacent to each other, thereby more reliably preventing the rod portion 5 from leaving the gap 17.

For this reason, the connection groove 19 formed in the inner peripheral surface of the spaced-apart strut portion 16 of the second part 2 is omitted, and instead, a connection groove 19 located on the spaced-apart strut portion 16 of the second part 2 in a diagonal manner is omitted. At the end edge, a pair of thin-walled inserting parts 16b are integrally provided, and each thin-walled inserting part 16b is inserted into the gap between the side surface of the rod part 5 and the inner surface of each rib wall 6 . Therefore, a structure is adopted at the same time, wherein: in the state where the rod portion 5 of the first member 1 is inserted into the gap 17 between the separated pillar portions 16 of the second member 2, the rod portion 5 is connected to the branch. The lower ends of the spaced pillar portions 16 are connected to each other so that they cannot be separated from each other, and when the pillar portions 12 of the second part 2 are pressed into the mounting holes H1 and H2, the lower ends of the spaced pillar portions 16 are avoided. Undesirable creases appear.

Next, as shown in FIG. 11, on the lower surface of the enlarged head portion 4 of the first piece 1, a stepped portion 4a is formed, and on the upper surface of the flange portion 11 of the second piece 2, a step portion 4a opposite thereto is also formed. Step portion 11a. The setting structure is such that in the state where the first piece 1 and the second piece 2 are integrated, a fixed gap is formed between the enlarged head 4 of the first piece 1 and the flange portion 11 of the second piece 2, resulting in Yes, if the operator, while gripping the enlarged head 4 of the first piece with his fingers, pulls out the stem portion 5 of the first piece 1 from the space 17 between the separated strut portions 16 of the second piece 2, The enlarged head 4 of the first piece 1 can be lifted for easy handling. It should be noted that, obviously, in this case the enlarged head portion 4 is larger in diameter than the flange portion 11 .

Accordingly, in the case where the top trim P1 is similarly fixed to the top cover P2 by using the clips of the above structure, similarly, in order to integrate the integrally formed first piece 1 and the second piece 2, if the small bridge pieces are first cut off 3. The first piece 1 and the second piece 2 can be integrated by inserting the rod portion 5 of the first piece 1 into the gap 17 formed between the separated pillar portions 16 of the second piece 2 . However, in this case, a fixed gap is formed between the enlarged head portion 4 and the flange portion 11, and the socket portions 16b (provided at the end edges of the separated pillar portions 16 of the second member 2) engage In the gap between the side surface of the stem portion 5 of the first member 1 and the inner surface of each rib wall 6, the separated strut portions 16 are connected to each other through the stem portion 5 so that they cannot be separated from each other.

After reaching the state where the first piece 1 and the second piece 2 are integrated, the top decoration P1 is superimposed on the top cover P2 to achieve a state where its mounting holes H1 and H2 are aligned, and the pillar part 12 is pressed into the Mounting holes H1 and H2. Then, in the process of passing the elastic blades 18 provided on the outer peripheral surfaces of the divided pillar portions 16 in a multi-stage manner through the mounting holes H1 and H2, the elastic blades 18 are pressed by the inner peripheral surfaces of the mounting holes H1 and H2. and bent, and, after passing through the rear side of the mounting holes H1 and H2, the elastic blade 18 returns to its original state, thereby preventing the second member 2 from coming out of the mounting holes H1 and H2. As a result, although not specifically shown, the top trim P1 is securely and firmly fixed to the top cover P2 in the same manner as the first embodiment.

In the case where the clip itself is reversely removed from the mounting holes H1 and H2 to release the fixed state of the top decoration P1 and the top cover P2, if the operator holds the enlarged head 4 of the first part 1 tightly with his fingers (due to the existence of a gap) While lifting) while pulling out the rod portion 5 of the first piece 1 from the gap 17 between the separated pillar portions 16 of the second part 2, the rod portion 5 formed on the rod portion 5 and each separated The gap 20 between the pillar parts 16 gradually pulls the rod part 5 of the first part 1 out of the space 17 between the separated pillar parts 16 . At this time, the pair of locking projections 8 are inseparably engaged with the engaging shoulders 15 provided on the inner peripheral surface of the opening 13, and a pair of newly provided side locking projections 21 are adjacently formed under the flange portion 11. Grooves 14 in the surface. Therefore, compared with the case of the first embodiment, the first part 1 and the second part 2 can be more reliably prevented from being erroneously separated by virtue of the paired engagement and paired abutment action. It should be noted that, as a result, in the same manner as in the first embodiment, there is no hindrance to the mutual approach of the separated pillar portions 16 in the gap 17 .

Accordingly, if the first piece 1 is subsequently removed from the mounting holes H1 and H2 together with the second piece 2 in the locked state while continuing to hold the enlarged head 4 of the first piece 1, due to the gap 17, The divided strut portions 16 are largely deflected inwardly, as shown in FIG. 12 . Therefore, even if the multi-stage elastic blade 18 extends obliquely upward, there is actually no need to bend the multi-stage elastic blade 18 in the opposite direction, so that the clip itself can be removed by applying a light force with the operator's fingers instead of using the conventional method. tools in .
