Problems solved by technology

However, the existing electric welding tongs on the market are still in the same system for decades and have a lever structure. A large spring is used to drive the lever to clamp the welding rod. This structure itself determines that the installation and replacement of the welding rod is laborious and difficult for welders with small hands Operation, due to the short arm of holding the welding rod, the welding rod is not held firmly

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] As shown in the figure, the electric welding tongs includes a jaw and a housing 5. The jaw is made of a jaw frame 3 and a clamping device 4 made of a conductor. Connect, have v-shaped groove 31 in the middle of its front; This v-shaped groove is to deposit welding rod usefulness. The clamping device 4 is composed of a clamping plate 41 whose end face is provided with a v-shaped opening opposite to the v-shaped groove, and a push rod 43 connected thereto and a spring 44 behind it, and the spring force directly passes through the v-shaped The shaped mouth clamping plate 41 acts on the welding rod completely, so that the welding rod is in a stable position. The middle position of the push rod 43 is provided with a push button 6 that is movably connected with the pin shaft 46, and the push button 6 is connected to the housing 5 through a push button shaft 65, and...

Abstract

The invention relates to a welding clamper used to mount and replace welding bar. Wherein, it is formed by clamping support and clamper made from conductors; the support has V-shape groove; the clamper is formed by clamping plate whose end surface has V-shape cut relative to the V-shape groove, connected pushing rod, and spring; the middle of pushing rod has pushing button; the wire is through the chamber of frame, while its front end is connected to the upper end of support and tail is connected to cable via screw; the frame of support has cover connected to the front of frame. The invention will not hurt head in welding.

Description

technical field [0001] The invention relates to the technical field of electric welding tools, in particular to electric welding pliers. Background technique [0002] With the rapid development of my country's industry, the workload of manual electric welding is also increasing day by day. As an important tool for manual electric welding, the technological progress of electric welding pliers is attracting great attention. However, the existing electric welding tongs on the market are still in the same system for decades and have a lever structure. A large spring is used to drive the lever to clamp the welding rod. This structure itself determines that the installation and replacement of the welding rod is laborious and difficult for welders with small hands Operation, due to the short arm of the clamping electrode, the clamping of the electrode is not stable or firm. Contents of the invention [0003] Aiming at ...
