[0002] The tungsten needle clamp in the welding gun is mainly responsible for fixing the tungsten needle and ensuring the stability of the electrode during the welding process. By accurately controlling the position and direction of the tungsten needle, the welding gun can achieve high-precision welding operations and ensure welding quality. However, the tungsten needle clamp in the prior art also has some defects. For example, the design of some clamps is not reasonable enough, which may cause the tungsten needle to loosen or fall off during the welding process, affecting the welding effect. It may be deformed or damaged at high temperatures, which in turn affects the welding quality and requires maintenance and replacement. The manufacturing cost of some existing welding gun fixed tungsten needle clamps is too high, which limits their promotion in practical applications. Clamping through some pneumatic devices is not only difficult to operate but also easy to damage the surface of the tungsten needle clamp. In addition, the manufacturing process of the welding gun shell is relatively complicated, and the cost of replacing a new shell is relatively high. Utility Model Content
