Of course, other transmission mechanisms, such as chain sprockets, etc., that perform the same function may be selected in other embodiments.
In the present embodiment, the description is made by sharing the same motor, and the propulsion device includes an eccentric wheel 200 connected to the wheel shaft 101 of the driven synchronous pulley 100 through another transmission mechanism, a link mechanism 201 having one end hinged to the eccentric wheel 200, a connection block 202 hinged to the other end of the link mechanism 201, and a push rod 203 fixedly connected to the connection block 202.

When the eccentric wheel 200 rotates under the drive of the first motor, the eccentric wheel drives the connecting block 202 and the push rod 203 to do linear reciprocating motion through the first connecting rod and the second connecting rod. In order to make the reciprocating movement of the push rod 203 smoother, the pushing device further comprises a first guide rail 204 arranged on the frame, and the push rod 203 is slidably arranged in the first guide rail 204.

In the present embodiment, the lever mechanism includes a lever 219 rotatably provided on the frame, a top block 220 provided at one end of the lever 219 in contact with and connected to the second roller 218, a third nut 221 provided at the other end of the first lever 219, and an adjusting screw 222 screwed with the third nut 221. The lever 219 is rotatably provided to the frame by a pin or the like so that the lever can rotate around the pin. In order to ensure that the second roller 218 is in effective contact with the top block 220, a second spring is further provided, one end of the second spring is connected with the lever 219, and the other end of the second spring is connected with the lifting arm 210, wherein the second spring is arranged in such a way that the second spring is always in a stretching state in the lifting process of the lifting arm 210, so that the second roller 218 is always in contact connection with the top block 220 through the elastic acting force of the second spring.
The extension length of the adjusting screw 222 at the other end of the lever in the third nut 221 is adjusted according to actual needs, specifically, the extension length of the adjusting screw 222 is as follows: when the low-point working surface of the first cam 205 is in contact with the first roller 214, the lifting arm 210 is lowered to the limit position at this time, the adjusting screw 222 is not in contact with the chain claw swing link 206, and when the high-point working surface of the first cam 205 is in contact with the first roller 214, the lifting arm 210 is raised to the limit position at this time, and the adjusting screw 222 presses the chain claw swing link 206 downward. After the adjustment is completed, when the high-point working surface of the first cam 205 rotates to be in contact connection with the first roller 214 from the low-point working surface of the first cam 205, the first roller 214 moves downwards under the driving of the first cam 205, the lifting arm 210 connected with the first roller 214 drives the connecting rod 209 and the sliding block on the connecting rod to move downwards in the second guide rail 207, at this time, the second roller 218 also drives one end of the lever 219 to rotate downwards, the adjusting screw 222 positioned at the other end of the first lever 219 rotates upwards, and at this time, the adjusting screw 222 is not in contact with the chain claw swing rod 206; when the low-point working surface of the first cam 205 rotates to contact with the first roller 214 from the high-point working surface of the first cam 205, the first roller 214 drives the lifting arm 210 and the second roller 218 to rise to the limit positions, the second roller 218 rises and pushes the first lever 219 to rotate upwards, and the adjusting screw 222 at the other end of the first lever 219 rotates downwards to press the chain claw swing rod 206.
