[0035] The connecting shaft 7 and the limiting column 11 are fixedly integrated. Figure 4 It can be directly seen that the components of the push block 5 are installed inside the mounting seat 6.

[0037] This embodiment from Figure 6-Figure 9 In the description, the output push rod 2 is driven to rise and fall by the clamping claw cylinder 1, so as to drive the push block 5 to slide in the push groove 4, thereby driving the connecting shaft 7 connected to the push block 5 to move, so as to realize the mutual expansion or closing movement of the auxiliary left clamping claw arm 25 and the auxiliary right clamping claw arm 26 through which the connecting shaft 7 moves, and the connecting shaft 7 is lifted and lowered in an arc shape in the arc groove 20 on the mounting seat 6 during the movement process. The connecting shaft 7 passes through the auxiliary left clamping claw arm 25 and the auxiliary right clamping claw arm 26, so the lifting and lowering of the connecting shaft 7 will also drive the auxiliary left clamping claw arm 25 and the auxiliary right clamping claw arm 26 to expand or close each other.
[0038] When the connecting shaft 7 is lifted or lowered, the auxiliary left clamping arm 25 and the auxiliary right clamping arm 26 are driven to expand or close to each other.

[0040] During specific work, the existing mechanical claws are large in size, heavy in weight, and have low gripping force. When peeling, the wires are often not clamped tightly and the claws slip, resulting in the equipment being unable to peel well. Therefore, the pneumatic component is designed to drive the connecting component to perform lifting movements, thereby cooperating with the claw arm assembly 8 to complete the mutual expansion or contraction movement, and finally to achieve the closure of the claws.
[0041] The two sides of the wire splitting slider 10 are respectively designed with a clamping arm assembly 8, so the clamping arm assemblies 8 on both sides can use the wire splitting slider 10 as an intermediate axis, and the clamping arm assemblies 8 on both sides can make a closing or opening movement on the side of the wire splitting slider 10. The clamping arm assembly 8 on one side cooperates with the side wall of the wire splitting slider 10 to form a clamping space for grabbing the wire alone. Figure 1 It can be directly seen in the figure that the clamping claw arm assemblies 8 on both sides cooperate with the two sides of the wire splitting slider 10 to complete the grabbing of two wires at one time.
[0042] One mechanical gripper assembly is used to grasp two wires, so the mechanical gripper doubles the work efficiency and reduces the cost. The designed mechanical gripper assembly has a lightweight effect.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
