Specifically, the cylinder includes a fixed portion 201 and a telescopic portion 202, and two magnetic valves 203 are fixed to the fixed portion 201 of the cylinder, and when the magnetic valves 203 are exhausted, the telescopic portion 202 of the cylinder is retracted and reset. The end of the expansion part 202 is fixed with a floating joint 204, specifically, one end of the driving rod, which is far away from the air cylinder, is hinged with the clamping part, one end of the floating joint 204 is sleeved at the end of the expansion part 202 and is fixed by a nut, and the other end of the floating joint is in reciprocating motion with the driving rod on the fixing plate 10. The drive rod includes an integrally formed connection block 2051 and a control block 2052, the diameter of the control block 2052 being smaller than the diameter of the connection block 2051. The connection block 2051 is adjacent to the floating joint 204, and the control block 2052 is connected to the clamping portion. When the telescopic part 202 of the air cylinder contracts, the telescopic part drives the floating joint 204 to contract inwards, and meanwhile, the driving rod moves in a direction away from the clamping part; when the telescopic part 202 of the air cylinder stretches out, the telescopic part drives the floating joint 204 to stretch out, and meanwhile, the floating joint 204 drives the driving rod to move towards the direction close to the clamping part.
Referring to fig. 1-2, the end of the drive rod remote from the floating joint 204 is secured to the clamp. Specifically, the clamping portion includes a base 301, a connecting rod, a clamping jaw, a positioning needle 306, and a positioning needle 306 platen 305.
