The guider of second embodiment of the invention and first embodiment are essentially identical, unlike first embodiment,
As shown in figure 9, the number of press part 240 is two, gap 243 is set between adjacent press part 240.This way it is possible to avoid
When press part 240 is moved radially outward, due to the influence of the situation of some discontinuity, the adjacent end of press part 240
Contact and produce interference.It is of course also possible to gap 243 is not provided with, because two press parts 240 are split settings, general
In the case of, when being moved radially outward, adjacent press part 240 is natural to be separated press part 240, produce gap.Certainly, compress
The number of part 240 be also not limited to two or three, four it is even more more.
Referring to Figure 10, in the present embodiment, being provided between adjacent press part 240 prevents press part in installation process
The 240 series connection parts 245 to drop.Because two press parts 240 are split settings, in installation and guide device because operation is rocked
Or stress, easily press part 240 is dropped from guide base, be not easy to the Fast Installation of guider.Series connection is set
Part 245 can easily solve this problem.
Specifically, part 245 of connecting is made of flexible material, such as using glass fibre yarn, common cloth, as long as energy will be adjacent
Press part 240 be together in series, while without prejudice to the normal operation of guider.In the present embodiment, 240 liang of press part
Two suspension ring 246 are set respectively in end sidewalls, and the suspension ring 246 that series connection part 245 is each passed through on two neighboring press part 240 connect
It is connected together, so as to which adjacent press part 240 be together in series.The joint of series connection part 245 can use what is knotted or be glued
Mode connects.The length of series connection part 245 is insulated on inside pipe wall with moving radially and being pressed on without prejudice to press part 240 after concatenation
It is defined.Certainly, the invention is not limited in this, suspension ring 246 can be arranged on the end sidewalls of press part 240 either medial surface or
On optional position on lateral surface, as long as the series connection of adjacent press part 240 can be realized.It is obvious also possible to it is not provided with
Suspension ring 246, and by the both ends for part 245 of connecting respectively with glue sticking on adjacent press part 240.
Embodiment three：
The guider of third embodiment of the invention and second embodiment are essentially identical, unlike second embodiment,
As shown in figure 11, press part 340 is in circular arc, and series connection part 345 is to be arranged on the length on the one end of press part 340 and to stretch out
Strip arc convex, the arc groove 347 being engaged with strip arc convex is set on the other end of press part 340.
Referring to Figure 11, the structure of series connection part 345 and arc groove 347 is schematically shown in figure.Specifically, series connection part
345 are integrally formed with press part 340, can be arranged on the upward optional position of the end axis of press part 340, the edge of arc groove 347
Axially through setting, width and the length of arc groove 347 are all higher than connecting the width and length of part 345.During series connection, by two
Adjacent press part 340 is close, series connection part 345 is inserted in corresponding arc groove 347, you can realize adjacent press part
Series connection between 340.When press part 340 is moved radially outwards, series connection part 345 exits from arc groove 347 therewith.
Certainly, the present invention is not limited to this, and arc groove 347 can not also penetrate setting vertically, but only set
For the groove of series connection part 345 can be housed, as long as arc groove 347 can match somebody with somebody merging with part 345 of connecting can smoothly realize both
Between insertion with separating.Series connection part 345 can also be molded with the split of press part 340, then will connect part 345 be welded on to
On casting die 340.Or series connection part 345 can also use other materials, it is bonded in again after being such as molded using plastics, resin material
On press part 340.
Referring to Figure 11, in the present embodiment, series connection part 345 is strip arc convex, and concentric with press part 340, its is straight
Footpath and the diameter of press part 340 are adapted, and its arc length is defined by can smoothly realize with the insertion of arc groove 347 with separating.
Connect end of the part 345 away from press part 340 is smooth flat, it is clear that the present invention is not limited to this, referring to Figure 12-Figure 14, its
End can also be arc-shaped, triangle or the other shapes such as polygon-shaped.
Example IV：
The guider of fourth embodiment of the invention and 3rd embodiment are essentially identical, unlike 3rd embodiment,
As shown in figure 15, part 445 of connecting is strip arc convex, and the end set thereon away from press part 440 radially protrudes
Stop part 448, arc groove 447 and the extraneous end set stopper section 449 communicated.It can so avoid series connection part 445 complete
Full abjection arc groove 447, can further prevent press part 440 to be scattered when mounted.
Specifically, stop part 448 is the ball extended from strip arc convex end, and the diameter of ball is slightly less than
The width of arc groove 447.Stopper section 449 is for the end set of arc groove 447 along press part 440 in the radial direction to groove
Two projections of center extension, the strip arc convex that the gap between two projections is available for connecting on part 445 pass through.This
Sample, when press part 440 is moved radially outwards, stopper section 449 coordinates with stop part 448 prevents two adjacent press parts
440 are kept completely separate, so as to prevent press part 440 to be scattered when mounted.
Certainly, the present invention is not limited to this, and referring to Figure 16-Figure 19, stop part 448 can also be cuboid, triangular prism, half
Cylinder or section are pentagonal prism, or are prisms that other sections are polygon etc..
Embodiment five：
The guider 500 and first embodiment of fifth embodiment of the invention are essentially identical, different from first embodiment
It is that as shown in figure 20, protector 512 is arranged on the inwall of main pilot hole 513.Fixture 550 is arranged on press part 540 and led
To between pedestal 510.
Specifically, similar to first embodiment, protector 512 is placed on step surface 517, the lower surface of fixture 550
It is pressed on the upper surface of protector 512, the bottom surface of press part 540 is pressed on the upper surface of fixture 550, so as to prevent
Guard 512 is fixed on the inwall of main pilot hole 513.
It will be clear that the invention is not limited to the exemplary this, can also be all provided with the inwall of main pilot hole 513 and auxiliary pilot hole 514
It is equipped with protector.Fixture 550 can also be split, and the part that such as will be far from control piece 520 hollows out, and only retain control piece
Part near 520, as long as protector 512 can be fixed.Or referring to Figure 21, protector 512 and fixture 550 1
Body is set, and is made of abrasion-proof insulating material, is directly anchored to aid on the inwall of pilot hole 514.
Embodiment six：
The guider 600 and first embodiment of sixth embodiment of the invention are essentially identical, different from first embodiment
Be, as shown in Figure 22 and Figure 23, guider 600 be not provided with axially through steam vent, but respectively in conversion of motion part
The axially arranged through slot 634 being adapted with the size of gap 643 on 630 outer walls, on the outer wall of guide base 610 it is axially arranged with
The adaptable through slot 619 of the size of gap 643.When assembling guider 600 so that through slot 634, gap 643 and insertion
Groove 619 is located axially on same bus, so as to be upwardly formed the air discharge duct of up/down perforation in the axle of guider 600.
The technology contents and technical characterstic of the present invention have revealed that as above, it being understood, however, that in the creative ideas of the present invention
Under, those skilled in the art can make various changes and improve to said structure and material, including individually discloses or want here
