The technical scheme of the invention is as follows: the hollow stud is in threaded connection with the lower clamp body. By adopting the technical scheme, after the threads of the hollow stud are worn, only the hollow stud can be replaced without replacing the whole lower clamp body, so that the maintenance cost is reduced.
The technical scheme of the invention is as follows: the upper clamp body, the lower clamp body, the hollow stud, the locking nut and the opening sleeve are all made of red copper.
The technical scheme of the invention is as follows: the upper clamp body and the lower clamp body are provided with V-shaped clamping grooves, and the clamping grooves comprise 0-degree clamping groove, 90-degree clamping groove, 60-degree clamping groove and 120-degree clamping groove. By adopting the technical scheme, the special welding tongs for the high-frequency direct-current switch cabinet can clamp welding rods at 0 degree, 60 degrees, 90 degrees and 120 degrees respectively so as to meet different use requirements.
Compared with the prior art, the special welding tongs for the high-frequency direct-current switch cabinet has the beneficial effects that: (1) the notch is arranged on the opening sleeve, so that when the cable core is inserted into the opening sleeve, the opening sleeve can deform to a certain extent, and the cable core can be conveniently inserted; (2) after the cable core is inserted into the opening sleeve, the opening sleeve penetrates through the locking nut and is inserted into the hollow stud, the locking nut is screwed, the elastic locking sheet is gradually extruded inwards by the guide surface on the locking nut along with the movement of the locking nut, the opening sleeve is locked, the opening sleeve generates certain deformation to lock the cable core, and therefore the opening sleeve can be tightly attached to the cable core, the cable core is well contacted with a special welding tongs for a high-frequency direct-current switch cabinet, and the cable core is not easy to loosen and fall off; (3) according to the invention, the cable core can be locked only by screwing the locking nut, so that the method is more convenient and faster compared with a screw fastening mode.
