Specific embodiment
As shown in one of attached drawing 1-3, the present invention includes pedestal 1, the first rack gear for being movably arranged on the pedestal 1
2 and second rack gear 3, the geared system 4 being fixed on pedestal 1, driving first rack gear 2 and the opposite pedestal 1 of the second rack gear 3 move
The end of dynamic driving device 5, first rack gear 2 and the second rack gear 3 is fixedly connected with the first push rod 21 and second respectively and pushes away
Bar 31, first rack gear 2 and the second rack gear 3 are arranged in the two sides of geared system 4 and are meshed respectively with geared system 4, institute
Stating geared system 4 includes gear 41 and gear shaft 42, and gear shaft 42 is fixed on pedestal 1, and gear 41 and the rotation of gear shaft 42 connect
It connecing, the driving device 5 includes input shaft 51, connecting rod 52 and pulley groove 53, and the pulley groove 53 is fixed on the first rack gear 2,
One end of the connecting rod 52 is fixedly connected with input shaft 51, and the other end and pulley groove 53 of connecting rod 52 are slided or rolled and connect, institute
Stating input shaft 51 drives connecting rod 52 to make rotating motion, and the connecting rod 52 drives the first rack gear 2 to do reciprocating linear by pulley groove 53
Movement, the first rack gear 2 drive the second rack gear 3 to do linear reciprocating motion, the first rack gear and the second rack drives by geared system 4
First push rod and the second push rod do linear reciprocating motion and push part thread-changing.
Further, the pedestal 1 is equipped with two guide rails 11 being parallel to each other, first rack gear 2 and the second rack gear 3
It is separately positioned on two guide rails 11, the first rack gear reciprocatingly moves along guide rail respectively with the second rack gear.
Further, more than two support shafts 6, the support are respectively equipped on first rack gear 2 and the second rack gear 3
First rack gear 2 and the second rack gear 3 are supported on the top of guide rail 11 by axis 6, one end of the support shaft 6 and the first rack gear 2 and the
Two rack gears 3 are fixedly connected, and the other end of support shaft 6 is equipped with idler wheel 61, and the idler wheel 61 is arranged in guide rail 11.The idler wheel
61 outer circumference surface is connected on the side of guide rail 11, and an end face of the idler wheel 61 is connected on the bottom surface of guide rail 11.Pass through
The cooperation of idler wheel and guide rail, reduces the frictional force of the first rack gear and the second rack gear in moving process, and the outer circumference surface of idler wheel supports
It connects on the side of guide rail, while the transverse shifting of the first rack gear and the second rack gear can also be limited.
