The control member is used to control the sliding of the punch 11. The control member can adopt a handle of a cylinder 12 or a connecting rod 5 structure. In the embodiment of the present application, the control member is a cylinder 12. The end of the fixed jaw 1 away from the positioning pin 2 is fixed to the end of the cylinder 12. The piston rod of the cylinder 12 is fixed to the punch 11. The punch 11 is controlled to slide along the channel 4 by the cylinder 12.

[0033] Reference Figure 1 , Figure 3 and Figure 4 A control component is provided on the fixed clamping jaw 1, and the control component is used to control the movable clamping jaw 9 to move to be pressed or opened with the fixed clamping jaw 1. The control component includes a clamping arm 3, a support arm 6, a connecting rod 5 and a pull rod 7. The clamping arm 3 is hinged to the fixed clamping jaw 1, and the connecting rod 5 is located between the clamping arm 3 and the support arm 6. The two ends of the connecting rod 5 are respectively hinged to the clamping arm 3 and the pull rod 7. The pull rod 7 has two pieces and is symmetrically arranged on both sides of the connecting rod 5. The two ends of the pull rod 7 are respectively hinged to the fixed clamping jaw 1 and the connecting rod 5. Through the arrangement of the pull rod 7, support is provided for the connecting rod 5, and the rotation range of the connecting rod 5 is limited, thereby improving the reliability of connecting the clamping arm 3 and the support arm 6 through the connecting rod 5.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The movable clamping jaw 9 is hinged to the end of the clamping arm 3 away from the connecting rod 5, and the end of the support arm 6 away from the clamping arm 3 is hinged with a transmission pin 8.

At this time, the transmission pin 8 is located in the drive slot 112 and the transmission pin 8 is located at one end of the first long circular hole 1a close to the cylinder 12. As the punch 11 slides towards the bracket 14, the movable jaw 9 produces a downward pressing action. When the punch 11 drives the transmission pin 8 out of the drive slot 112 and into the stop slot 1b, the clamping pliers are in a clamped state, and the connecting portions 143 on both sides of the fixed portion 141 are in contact. The punch 11 continues to move under the action of the cylinder 12. The punch 11 first slides until the top pressure surface 113 of the punch 11 contacts one side of the connecting claw 142, and then the connecting claw 142 is bent by the force. When the punch 11 slides to the position where the transmission pin 8 is located at one end of the second long circular hole 111 close to the cylinder 12, the side pressure surface 114 of the punch 11 completely covers the connecting claw 142 and the clamping is completed.
