[0035] As shown in the figure, Figure 2 The transmission mechanism 2 can be configured as a first transmission mechanism 2a, which includes a transmission wheel 21a, a first transmission member 22a, and a second transmission member 23a arranged in parallel with the first transmission member 22a. In the present embodiment, the transmission wheel 21a can be configured as a gear, and the first transmission member 22a and the second transmission member 23a can be configured as a rack structure. In other embodiments of the present application, the transmission wheel 21a can also be a friction wheel, and the first transmission member 22a and the second transmission member 23a can be configured as a friction plate structure.

[0036] The transmission wheel 21a is rotationally connected with the base 11, the first transmission member 22a cooperates with the second transmission member 23a through the transmission wheel 21a, the execution end of the driver 17 abuts against the first clamp 12, so as to drive the first clamp 12 to move in the horizontal direction perpendicular to the radial direction of the transmission wheel 21a, so as to make the transmission wheel 21a rotate, and further drive the second clamp 13 to move in the opposite direction. In this embodiment, the output end of the driver 17 is used to perform linear motion, and at this time the driver 17 can adopt any one of an electric cylinder, a pneumatic cylinder and a linear motor.

[0037] The first transmission member 22a and the second transmission member 23a can be separate parts and are respectively fixed to the adjacent ends of the first clamp 12 and the second clamp 13, or are directly integrally formed as part of the adjacent ends of the first clamp 12 and the second clamp 13. The execution end of the driver 17 is coaxially fixed with the transmission wheel 21a, and can also be drivingly connected through the transmission device in the prior art.
