Bar 331 is not in rotation, it is ensured that support plate 338 is parallel with 2 surface of loading plate always, bar to be supported in moving process
After 331 position regulates, turntable 334 is rotated, and the worm screw 3310 in rotating bar 333 is driven to rotate synchronously, worm gear
335 are cooperatively connected with worm screw 3310, and when worm screw 3310 rotates, worm gear 335 occurs to turn with the rotation of worm screw 3310
Dynamic, 335 two sides telescopic rod of worm gear starts to extend at this time, support plate 338 is ejected, support plate 338 is respectively against loading plate 2 and L
31 inner surface of type shell, in this way when repairing loading plate 2, loading plate 2 can be completely fixed, and be not in that shaking causes to repair
It is inconvenient to mend.
One end of lower beam 336 is fixedly connected with worm gear 335, and the other end and rotation slot 3391 are rotatablely connected, can be by worm gear
335 are fixed on inside shell 339, and will not influence the normal rotation of worm gear 335, and after worm gear 335 rotates, lower beam 336 is therewith
Rotation, and due to the cooperation of sliding block 3371 and limit sliding chutes 3361, lower beam 336 will drive upper boom 337 and rotate synchronously, by
It is cooperatively connected in upper boom 337 and threaded hole 3392, therefore upper boom 337 can move up and down in the course of rotation, can drive
Support plate 338 moves up and down, and convenient for adjusting the position of support plate 338, baffle 3362 prevents the movement of upper boom 337 excessive, with
As for leaving limit sliding chutes 3361.
Embodiment two
Place unlike the embodiments above is:
As shown in figure 8,331 cross section of support rod is also possible to rectangle, in this way in front and back pulling and left-right rotation
During, the lower surface of support rod 331 can be preferably bonded with the inner surface of rectangular through-hole, keep movement more steady.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
