Joint metal piece of arc welding tongs and arc welding tongs thereof

Abstract

The invention relates to an electrode holders connecting iron part and electrode holders; wherein, the connecting iron part comprises a connecting iron part; the electrode holders comprise a handle, an upper copper head, a lower copper head, a bent handle, a connecting iron part and a recovery spring. The key point is that the front bottom surface of the lower copper head of the connecting iron part is provided with a lower copper head fastening screw hole, the middle part thereof is provided with a lower copper head latch notch and the tail thereof is provided with a lower copper head fastening pressing lug. The connecting iron part and the electrode holders have the advantages that the lower copper head is stably installed and is not easy to be loosened, the poor contact between the cable and the lower copper head is not easy to occur, ultra-high temperature is not easy to be generated, electric spark is not easy to be generated, the handle is not so hot to burn hands, the labor intensity during the electric welding can be greatly reduced, the efficiency of the electric welding is greatly improved, the electric welding cost is greatly reduced, the service life of the electrode holders is effectively prolonged, and the connecting iron part and the electrode holders are ideal updating products.

Description

technical field [0001] The invention relates to an electric welding pliers connecting iron pieces and the electric welding pliers. Background technique [0002] Existing electric welding tongs connect the iron parts and all utilize screws to set the lower copper head on the front part of the connected iron parts. It is easy to loosen, resulting in poor contact between the cable and the lower copper head, which can easily generate ultra-high temperature and even electric sparks, causing the handle to be extremely hot, and even damage the welding tongs. The labor intensity of the electric welding operator is increased, the electric welding efficiency is low, the electric welding cost is high, and the service life of the electric welding tongs is short. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an electric welding tongs connecting iron parts and its electric welding tongs which are firmly installed and...
