Lower step:
When the telescoping mechanism of present embodiment stretches out, driving mechanism pushes second level telescopic shaft 7 to be moved by its rear end forward end, from
And thimble 4 is pushed to be moved by its rear end forward end, so that the pyramidal structure of 4 front end of thimble and 3 front end of elastic expansion sleeve is interior
The conical surface matches (as shown in Figs. 1-3)；Since the force of sliding friction between first order telescopic shaft 2 and guide sleeve 1 is much smaller than top
The thrust of 4 distending elastic expansion sleeve 3 of needle, therefore when driving mechanism continues to press on, second level telescopic shaft 7, thimble 4, the first order are flexible
Axis 2 and elastic expansion sleeve 3 become a rigid body, i.e., second level telescopic shaft 7, thimble 4, first order telescopic shaft 2 and elastic expansion sleeve 3 at
It is integrally mobile relative to guide sleeve 1, until first order telescopic shaft 2 is directed to 1 axial limiting of casing, i.e. first order telescopic shaft
The rear end that 2 the first positioning shaft shoulder 20 is directed to casing 1 is blocked, and the front end of elastic expansion sleeve 3 penetrates machined to part at this time
In inner hole, the positioning of present embodiment telescoping mechanism and part is so realized；When first order telescopic shaft 2 is directed to 1 axis of casing
To when limit, driving mechanism is continued to press on, and first order telescopic shaft 2 and elastic expansion sleeve 3 are not moved relative to guide sleeve 1 at this time,
Second level telescopic shaft 7 and thimble 2 are continued to move to relative to guide sleeve 1, until the pyramidal structure of thimble 4 is pierced by elastic expansion sleeve 3
Front end, so that the front end of elastic expansion sleeve 3, by 4 distending of thimble (as shown in Figure 4), such 3 swelling part of elastic expansion sleeve is machined
Inner hole, driving mechanism stop pushing, and realize the reliable installation of present embodiment telescoping mechanism and part.In stretching for present embodiment
During contracting mechanism is stretched out, the cylindrical end of cylinder end clamping fixed screw 5 moves in the waist type groove 401 of thimble 4, does not interfere thimble
4, the movement of elastic expansion sleeve 3, first order telescopic shaft 2 and second level telescopic shaft 7.When first order telescopic shaft 2 is directed to casing 1 axially
When limit, first order telescopic shaft 2 and elastic expansion sleeve 3 are not moved relative to guide sleeve 1, and second level telescopic shaft 7 is relative to
There are also the distance moved forward, i.e. the second positioning shaft shoulder 70 of second level telescopic shaft 7 are flexible relative to the first order for level-one telescopic shaft 2
There is spacing between the seam allowance face of the third inner stopper of axis 2.
When the telescoping mechanism retraction of present embodiment, driving mechanism drives second level telescopic shaft 7 to be moved to the back-end by its front end
It is dynamic, so that thimble 4 is mobile to the back-end by its front end, so that thimble 4 bounces back in elastic expansion sleeve 3,3 not swelling of elastic expansion sleeve at this time
The machined inner hole of part；Driving mechanism continues to drive second level telescopic shaft 7 mobile to the back-end by its front end, when thimble 4 is mobile
When to the cylindrical end for hooking cylinder end clamping fixed screw 5, first order telescopic shaft 2, thimble 4, second level telescopic shaft 7 and elastic expansion sleeve 3
It is integratedly mobile relative to guide sleeve 1, so that elastic expansion sleeve 3 is deviate from from the machined inner hole of part, so realize
The fast demoulding of present embodiment telescoping mechanism, rear drive mechanism stop driving.
