The push rod is connected with a rotating pair, and one end of the push rod is provided with a push rod sleeve. The push rod is connected with the rotating block with a moving pair, and the rotating block is connected with the driven push rod with a rotating pair. The bottom end of the push rod is in contact with the driving cam through a partial roller.

Furthermore, the first-stage small gear drives the first-stage large gear to rotate to realize the first-stage deceleration; the first-stage large gear and the second-stage small gear rotate at the same speed, and the second-stage small gear drives the second-stage large gear to rotate to realize the second-stage deceleration; The second-stage large gear and the third-stage pinion rotate at the same speed, and the third-stage pinion drives the third-stage large gear to rotate to realize the third-stage deceleration.

Furthermore, the three-stage large gear rotates at the same speed as the driving cam and the crank, the driving cam and the driven push rod are in high contact, and the driven push rod and the slideway are constrained by a moving pair; the crank drives the slider through the connecting rod The rack moves back and forth, and the rack and slideways are fixed.

Furthermore, the left and right movement of the slider and the up and down movement of the driven push rod are combined to form the reciprocating oblique lifting motion of the push rod. The push rod has a horizontal posture at the limit position of left and right movement, and the push rod It has an oblique lifting attitude.

Compared with the prior art, the beneficial effects of the present invention are as follows: the principle is novel, the concept is ingenious, the operation is reliable, the stability is high, and it has a very broad commercial prospect. It can fill the gaps in related technologies, and can generate greater social benefits and economic benefits.
