Insulated picking clamp forged with pure copper

[0012] Such as figure 1 As shown, an insulated picking pliers made of pure copper, including upper pliers 1 and lower pliers 2, the rear end of the lower pliers 2 is a handle 3, and the clamping surface of the lower pliers 2 is provided with a conductive copper plate 4. The lower end is connected to the wire 5, and the lower clamp 2 has a channel for accommodating the wires. A fixing frame 6 is installed on both sides of the lower clamp 2. A hinge shaft 7 is installed on the fixing frame 6, and an upper clamp is installed on the hinge shaft 7. Clamp 1, the rear end of the upper jaw 1 is a pressing handle 8, and a return spring group 9 is provided between the pressing handle 8 and the lower jaw 2.

[0013] The connecting end of the fixing frame 6 and the lower jaw 2 is fixedly connected by a plurality of fixing screws.

[0014] The reset spring group 9 is composed of multiple powerful springs arranged side by side.

[0015] The outside of the handle 3 and the pressing handle 8 are provided with a shell made of insulating material.

[0016] The insulating material is preferably an elastic rubber material.

[0017] The upper clamp 1 and the lower clamp 2 are made of pure copper forging or pure copper plate forging.

[0018] The working process is as follows:

[0019] When you start to prepare for welding, press the pressing handle 8, the upper clamp 1 and the lower clamp 2 clamp the welding rod, and the upper clamp 1 and the lower clamp 2 are set in 1 upper clamp and 2 lower clamp. The side fixing frame 6 is hinged to improve the stability of the strain picking forceps. In addition, the replication spring set 9 can ensure the stability of the holding electrode.
