It will be appreciated that in the electrode holders of the present utility model, the shield 3 is attached to the handle 12 through the sleeve 21 assembly 2, whereby sparks generated by the welding rod and the welding object can be blocked by the shield 3 during the welding operation, preventing the spark from directly burning the welding glove, reducing the welding glove loss, and reducing the operation cost.

It should be noted that, in the sleeve 21 assembly 2, the plurality of clamping plates 22 are annularly arranged on the inner wall of the sleeve 21 to form a double-layer tubular structure, when the handle 12 is penetrated into the installation cavity surrounded by the plurality of clamping plates 22, the elastic piece 23 can drive the clamping plates 22 to handle 12 from a plurality of directions, thereby realizing the connection between the sleeve 21 and the handle 12, the protective cover 3 can be stably installed on the electric welding pliers, and compared with the mode of directly fixing the protective cover 3 on the electric welding pliers, the electric welding pliers can adjust the position of the protective cover 3 or detach the protective cover 3 at any time by pushing and pulling the sleeve 21, thereby improving the flexibility of the use of the protective cover 3 in welding operation.

The plurality of clamping plates 22 have a fit clearance therebetween, so that when the clamping plates 22 clamp the handle 12, the adjacent clamping plates 22 do not interfere with each other in movement, ensuring that the clamping lever can normally perform a clamping action on the handle 12.

Further, as shown in fig. 3, the side of the holding plate 22 facing the inner wall has a guide bar 24, the sleeve 21 has a limiting hole, and the guide bar 24 is movably fitted in the limiting hole.

It should be noted that, the elastic member 23 between the clamping plate 22 and the sleeve 21 is easily deformed due to stress, which causes the clamping plate 22 to swing randomly in the sleeve 21, and in the present utility model, a limiting structure is provided between the clamping plate 22 and the sleeve 21, that is, the guide rod 24 can only move along the opening direction of the limiting hole, so as to effectively control the movement direction of the clamping plate 22, improve the stability of the sleeve 21 assembly 2 for clamping the handle 12, and avoid the shaking of the protective cover 3 during the electric welding operation.

Further, as shown in fig. 2 and 3, the end of the guide rod 24 extending out of the limiting hole has a limiting protrusion 25, and the limiting protrusion 25 is stopped against the outer wall of the sleeve 21.

It will be appreciated that the limiting protrusion 25 can prevent the guide rod 24 from coming out of the limiting hole, so as to promote the stability of the cooperation of the guide rod 24 and the limiting hole, and meanwhile, the limiting protrusion 25 is also convenient for an operator to lift the clamping plate 22 from the outside of the sleeve 21, so that the sleeve 21 is loosened to adjust the position of the sleeve 21, or the sleeve 21 is taken out from the handle 12, and the applicability of the sleeve 21 assembly 2 is promoted.
