The main body housing 2 is formed by screwing a pair of left and right halves. The blade portion 4 is composed of a pair of upper and lower strip-shaped fixed plates 5 and 5 and two strip-shaped movable blades 6 between the fixed plates 5 and 5 and formed in a staggered shape on the left and right side edges. When the motor is driven by pushing the switch lever 7 provided on the upper handle 3, the movable blades 6 and 6 are moved back and forth in opposite directions by the crank mechanism. Reference numeral 21 denotes a lock-on button which is provided in the vicinity of the switch lever 7 in the upper handle 3 and holds the pushed state of the switch lever 7.

  As shown in FIG. 2, a lower handle 8 serving as a bowl-shaped insertion portion whose upper surface bulges out is extended at the rear lower portion of the main body housing 2, while the rear handle 8 At the end, a drooping portion 9 in which a rear end and a lower end of the lower handle 8 are divided at a predetermined interval is extended, and a joint handle 10 is connected to the drooping portion 9. This joint handle 10 has a curved shape whose outer cross-sectional shape matches the upper surface of the lower handle 8, and has an attachment portion 11 whose length in the front-rear direction is substantially the same as that of the lower handle 8 and an upper surface of the rear end of the attachment portion 11 A projecting ring-shaped joint portion 12, the joint portion 12 is fitted into a housing portion 13 provided in the hanging portion 9, and a pin 14 provided in the left-right direction in the housing portion 13 is connected to the joint portion 12. It is connected to the drooping portion 9 by passing through.

However, in this case, the joint portion 10 has a slight play in the vertical direction with respect to the outer shape of the joint portion 12 with respect to the outer shape of the joint portion 12, and the joint handle 10 is connected in a connected state. It can be finely moved up and down with respect to the hanging portion 9. That is, in the lower position of the joint handle 10 where the joint portion 12 abuts on the lower end of the accommodating portion 13, the attachment portion 11 abuts on the upper surface of the lower handle 8 and the joint portion 12 abuts on the upper end of the accommodating portion 13. At the upper position 10, the attachment portion 11 is separated from the upper surface of the lower handle 8, and a gap substantially equal to the thickness of the cover 18 described later is generated between them.
The joint handle 10 and the lower handle 8 are formed by connecting the tips of screws 16 and 16 as connecting means penetrating through the through holes 15 and 15 formed in the vertical direction of the lower handle 8 from below. It can be connected by screwing into nuts 17, 17 embedded in the upper part of the attachment part 11.

It can be fitted externally so as to cover the lower handle 8 from behind. Further, in a state where the cover 18 is pushed forward until it comes into contact with the projecting surface of the lower handle 8 in the main body housing 2, a through-hole 19 through which the screw 16 can pass in a vertical position corresponding to the through hole 15 of the lower handle 8. , 19... Are formed respectively. Reference numerals 20 and 20 denote protrusions that protrude in the front-rear direction above the inner surface of the cover 18 and abut against the left and right side surfaces of the lower handle 8 when attached to the lower handle 8 to suppress left and right rattling.

In the horticultural hair clipper 1 configured as described above, the lower handle 8 and the joint handle 10 are normally connected with screws 16 and 16 as shown in FIG. At this time, the operator can work while supporting the main body housing 2 by holding the upper handle 3 or simultaneously holding the attachment portion 11 of the joint handle 10 and the lower handle 8.
Then, when trimming is performed in a place where it is difficult to reach at normal times, the screws 16 and 16 are once removed to separate the attachment portion 11 of the joint handle 10 and the lower handle 8, and the cover 18 is attached to the lower handle 8. At this time, the cover 18 can be smoothly mounted between the attachment portion 11 and the lower handle 8 by retracting the joint handle 10 to the upper position. After the cover 18 is mounted, if the lower handle 8 and the cover 18 are screwed to the attachment portion 11 again with screws 16, 16, the cover 18 projects over the rear extension of the lower handle 8 as shown in FIGS. 3 and 5. It is connected to the main body housing 2 in such a manner. Therefore, the gardening clipper 1 can be extended forward by grasping the rear of the cover 18 and can be easily trimmed even in a distant place or a high place.

  As described above, according to the gardening clipper 1 of the first aspect, the main body housing 2 is provided with the connecting means that can connect the cover 18 in a protruding state from the main body housing 2, and the cover 18 is connected by the connecting means. Since the main body housing 2 can be supported, the cover 18 can be rationally used as an extension member of the main body housing 2. In particular, it is compact even when extended, and hardly increases in weight. In addition, there is no need for extra time for storage and transportation, and the cost can be reduced.

On the other hand, an insertion portion (lower handle 8) into which the cover 18 can be externally fitted is formed in the main body housing 2, and the cover 18 that is externally fitted to the lower handle 8 is fixed with screws 16. It can be reliably connected to the main body housing 2 in a stable state.
The lower handle 8 is also used as an insertion portion, and the body housing 2 is provided with an attachment portion 11 formed along the lower handle 8 and connectable to the lower handle 8 and the cover 18 by a screw 16. The cover 18 is sandwiched and fixed by the lower handle 8 and the attachment portion 11, and the body housing 2 can be more firmly integrated. Further, the insertion portion can be easily and rationally formed using the lower handle 8.
In particular, here, the upper surfaces of the lower handle 8 and the cover 18 are bulged, and the attachment portion 11 has a curved shape that matches this, so that the left and right sides of the attachment portion 11 with respect to the lower handle 8 and the cover 18 are rattled. Is effectively suppressed.

In this mode 1, play is provided so that the separate joint handle can be finely moved, but the hanging portion of the handle and the attachment portion are integrated, and the lower handle is separated from the main body housing. Therefore, it may be finely movable and may be connected so as to have play between the attachment portion. However, play is not indispensable, and if the attachment part and the lower handle have sufficient elasticity and the cover can be fitted externally, it is possible to eliminate play by integrally forming the attachment part on the hanging part. It is.
Further, a structure in which the joint handle is eliminated, the lower handle, the lower handle, and the divided hanging part are directly screwed together with screws, and the upper side of the cover is inserted between the two is also conceivable.

On the other hand, the insertion portion is not limited to the structure using the lower handle, and for example, a design change in which an insertion portion is formed on the upper handle and the cover is obliquely connected to the main body housing is possible.
In addition, if the screw is a thumbscrew or the like, the cover can be easily attached and detached without using a tool. Of course, other connecting means such as a belt may be employed in addition to the screw.

<< Form 2 >>
Next, another embodiment of the present invention will be described. Note that the same reference numerals are given to the same components as in the first embodiment, such as the basic structure of the gardening hair clipper, and duplicate description is omitted.
The gardening clipper 1 a shown in FIG. 6 is equipped with a slide grip 30 as a lower handle that becomes a part of the main body housing 2. As shown in FIGS. 7 and 8A, the slide grip 30 is a shaft body having a circular section in which a large-diameter portion 31 is formed at the front end and a small-diameter portion 32 is formed behind the large-diameter portion 31. A pair of engaging portions 33, 33 each having a plurality of circumferentially threaded threads without leads protruding at equal intervals in the longitudinal direction are formed. In addition, a pair of chamfered portions that are located on the same line as the engaging portion 33 in the axial direction are formed near the rear end when the large-diameter portion 31 is formed in the small-diameter portion 32 as shown in FIG. 34 and 34 are formed, respectively.

On the other hand, a cylindrical portion 35 that can be engaged with the large-diameter portion 31 of the slide grip 30 is formed in the lower rear portion of the main body housing 2. As shown in FIG. 8 (A), the cylindrical portion 35 has an inner diameter that can substantially accommodate the large-diameter portion 31, and the upper and lower portions of the inner periphery are provided with circumferential threads without leads in the axial direction. A pair of engaged portions 36 and 36 that can engage with the engaging portions 33 and 33 of the large-diameter portion 31 are formed in a point-symmetric manner. Therefore, in the direction of the large-diameter portion 31 in which the engaging portions 33 and 33 are positioned on the left and right sides, as shown in FIG. 5C, the engaging portion 33 does not interfere with the engaged portion 36. The portion 31 can be inserted into and removed from the cylindrical portion 35. When the large-diameter portion 31 is rotated so that the engaging portions 33 and 33 are vertically moved while being inserted into the cylindrical portion 35, the engaging portion 33 is provided. , 33 are locked to the engaged portions 36, 36, respectively, and the movement is restricted in the axial direction.
Also, a hanging portion 37 hanging downward from the rear end of the upper handle 3 is coaxial with the cylindrical portion 35, and the large-diameter portion 31 can be loosely inserted from the front. A second cylindrical portion 35a formed with 36 and 36 is formed.

  Further, behind the second cylindrical portion 35a, a holding cylinder 38 having a slightly larger diameter than the small diameter portion 32 of the slide grip 30 and allowing the small diameter portion 32 to be freely inserted is coaxial with the second cylindrical portion 35a. It is connected in series. In the accommodating portion 39 formed above the holding cylinder 38, a lock member 40 having a lower end which is a contact surface capable of contacting the chamfered portion 34 of the small diameter portion 32 is accommodated so as to be movable up and down. It is biased downward. An operation piece 43 is formed at the upper end of the lock member 40 so as to protrude rearward from a long groove 42 provided on the rear surface of the accommodating portion 39. The lock member 40 is at a lower limit position where the operation piece 43 contacts the lower end of the long groove 42. Has a lower end protruding into the holding cylinder 38. That is, the lock member 40 and the coil spring 41 serve as restriction means for restricting the rotation of the slide grip 30, and the cylindrical portion 35 and the second cylindrical portion 35a are combined with this to constitute the fixing means of the present invention.

  In the gardening clipper 1a configured as described above, the engaging portion 33 is usually engaged with the engaged portion 36 in a state where the slide grip 30 is inserted into the front cylindrical portion 35 as shown in FIGS. The slide grip 30 is used so as to fit in the main body housing 2 (installed position). At this time, the lock member 40 abuts on the chamfer 34 on the rear side of the slide grip 30 to restrict the rotation of the slide grip 30. Therefore, the operator can work while supporting the main body housing 2 by holding the upper handle 3 or holding the slide grip 30.

  Then, when trimming is performed at a place where it is difficult to reach during normal times, the lock member 40 is lifted upward against the bias of the coil spring 41 using the operation piece 43 to release the rotation restriction. If the slide grip 30 is rotated 90 degrees in this state as shown in FIG. 8C, the engagement between the engaging portion 33 and the engaged portion 36 can be released. Next, if the slide grip 30 is moved backward as it is and the large diameter portion 31 is inserted into the second cylindrical portion 35a and the slide grip 30 is rotated again by 90 degrees, the engaging portion 33 is now turned into the second cylindrical portion. Engage with the engaged portion 36 in 35a (protruding position). Here, when the push-up of the lock member 40 is released, the lock member 40 comes into contact with the front chamfered portion 34 and restricts the rotation of the slide grip 30 as shown in FIG. Thus, the gardening clipper 1a can be extended forward by grasping the slide grip 30 protruding rearward, and can be easily trimmed even in a distant place or a high place.

  As described above, also in the gardening clipper 1a of the above-described form 2, the slide grip 30 can be moved between the protruding position protruding from the main body housing 2 and the built-in position within the main body housing 2, and By providing a fixing means capable of fixing the slide grip 30 and enabling the main body housing 2 to be supported via the slide grip 30 fixed at the protruding position, the slide grip 30 can be rationally used as an extension member. In particular, it is compact even when extended, and does not increase in weight. In addition, there is no need for extra time for storage and transportation, and the cost can be reduced.

In particular, since the slide grip 30 serving as the lower handle can be moved to the protruding position as a part of the main body housing 2, an extension member can be obtained with a simple configuration using the slide grip 30.
The slide grip 30 can be moved back and forth between the front mounting position and the rearward projecting position, and the fixing means can be freely inserted into the slide grip 30, and the outer periphery of the front end of the slide grip 30 at a predetermined rotational position of the slide grip 30. A cylindrical portion 35, 35a that engages with the engaging portion 33 provided on the inner surface and restricts forward and backward movement; a lock member 40 that restricts rotation of the slide grip 30 in an engaged state with the tubular portion 35, 35a; and a coil spring By using 41, the operation of moving the slide grip 30 to the installation position and the protruding position can be easily performed, and the operability related to the use of the slide grip 30 is improved.

Note that the coupling between the slide grip and the cylindrical portion is not limited to the engagement structure with a thread without a lead as in the above-described form, and the slide grip can be screwed into the cylindrical section with a thread with a lead, or a simple insertion and removal. There is no problem even if it is structured and connected with pins or screws. Further, not only the engagement of threads, but if the forward / backward movement of the slide grip can be regulated, one or a plurality of protrusions or protrusions can be simply engaged, or the L-shaped groove and protrusion can be used. A bayonet coupling may be employed.
In addition to moving the slide grip back and forth in the axial direction, the slide grip can be rotated with the connecting part with the hanging part as a fulcrum, and the main body housing and screws etc. on the forward rotation side (installation position) Even if it can be coupled with a screw or the like as it is on the rear rotation side (projecting position), it can be used as an extension member. Needless to say, the lower handle (slide grip) is not limited to the extension member, and the upper handle and other portions can be moved to the protruding position.

In addition, in common with forms 1 and 2, the configuration of the gardening clipper itself is not limited to the above form. For example, one of the blades may be a fixed blade, the other may be a movable blade, and there is no upper handle on the upper side. The present invention can also be applied to a main housing provided with only a lower handle.
