Description of the drawings：
The utility model is described further with reference to specific legend：
Fig. 1 is screw inclined plane displacement mechanism schematic diagram
Wherein
1-fixed part the 11-the first sliding sleeve 13-limiting plate of the 12-the second sliding sleeve
2-driving portion, 21-preloading spring, 3-inclined plane slide block, 31-inclined-plane
4-spring, 5-displacement drive, 51-screw rod, 511-annular groove
512-knob, 52-nut drive rod α-angle of inclination
Specific embodiment：
With reference to Fig. 1, screw inclined plane displacement mechanism drives including fixed part 1, driving portion 2, inclined plane slide block 3, spring 4 and displacement
Dynamic device 5；Displacement drive 5 includes screw rod 51 and nut drive rod 52；Screw rod 51 is matched somebody with somebody with 52 screw thread of nut drive rod
It closes, 52 moving back and forth of nut drive rod is driven by screw rod 51, screw rod 51 can only be done by a limiting plate 13 constraint on fixed part 1 to be revolved
Turn；More specifically, 51 outer end of screw rod is machined with an annular groove 511, and limiting plate 13 is folded on the annular groove 511, constrains screw rod 51
It is axially moved, the locking of 51 outer end of screw rod has adjusting knob 512, has both facilitated adjusting, and knob 512 can also be designed to angled turn
Disk facilitates experimental observation.
The nut drive rod 52 is constrained in the first sliding sleeve 11 of fixed part 1, can only do linear reciprocating motion, the spiral shell
Female 52 end of drive rod is contradicted in the wide bottom end face of inclined plane slide block 3；The slip of inclined plane slide block 3 is hubbed in the sliding slot of fixed part 1, bullet
Spring 4 is contradicted between fixed part 1 and the tip end face of inclined plane slide block 3, is generated by spring 4 to eliminate when screw rod 51 is retreated and adjusted
