Embodiment Construction
[0010] The structure of electric welding tongs of the present invention is as figure 1 and figure 2 As shown, the welding tongs of the present invention is composed of a handle 4, a main clamping rod 3, a main clamping rod cover 1, a secondary clamping rod 6, and a secondary clamping rod cover 5. The front ends of the main clamping rod 3 and the secondary clamping rod 6 form jaws for clamping the welding rod. The outer surfaces of the main clamping rod 3 and the secondary clamping rod 6 are respectively connected with the main clamping rod cover 1 and the secondary clamping rod cover 5, which play the role of insulation. On the basis of the straight jaws, extend and connect the jaws 7, and the angle between the jaws 7 and the jaws is 135 degrees. The effect of jaw 7 is to replace that section of welding rod that is discarded, helps line of sight not to be blocked, can reduce the depth that welding rod is inserted into jaw, reaches the purpose of saving welding rod. The inn...

Provided is an electric welding clamp. A handle is connected with a main clamping rod, an auxiliary clamping rod is installed on the main clamping rod, a clamp opening for clamping a welding rod is formed at the front ends of the main clamping rod and the auxiliary clamping rod, a main clamping rod cover casing is installed on the outer portion of the main clamping rod, an auxiliary clamping rod cover casing is installed on the outer portion of the auxiliary clamping rod, a bending clamp opening is extended from the head end of the clamp opening, a rib strip is respectively arranged in the main clamping rod cover casing and the auxiliary clamping rod cover casing, and two clamping grooves are arranged on the surface of the inner wall of the clamp opening. According to the electric welding clamp, a main clamping groove is arranged at position close to the most front end of the clamp opening to avoid the fact that the main clamping groove blocks a sight line. Due to the fact that the rib strips are arranged on the outer surface of the main clamping rod and the auxiliary clamping rod, the main clamping rod cover casing and the auxiliary clamping rod cover casing are fixed at the back of the main clamping rod and the auxiliary clamping rod in casting method. The cover casings are not easy to fall, screws are not used for fixing the cover casings, and cover casing thickness can be reduced. The cover casings cannot block the view line in the welding process.
Description
technical field [0001] The invention relates to an arc welding device, in particular to an electric welding clamp. Background technique [0002] Currently used electric welding tongs, the upper jaw and the lower jaw are relatively thick, with a width and thickness of more than 40mm, and the main clamp groove for clamping the welding rod is arranged in the middle of the jaws. The electric welding tongs of this structure seriously blocks the line of sight during welding, making welding inconvenient. Contents of the invention [0003] In order to overcome the above-mentioned defects existing in the existing electric welding tongs, the present invention provides an electric welding tongs with a wide viewing angle during welding. [0004] The technical solution adopted by the present invention to achieve the above object is: an electric welding pliers, the handle is connected to the main clamping rod, the auxiliary clamping rod is installed on the main clamping rod, and the fr...
