The right side of the limit member 11 is fixedly connected to a connecting block 12, which passes through the through groove, and the right side of the connecting block 12 is fixedly connected to a slide buckle 4. The slide buckle 4 is slidably connected to the lower gun body 5. A switch button 8 is provided on the left side of the lower gun body 5, and a handle 9 is fixedly connected to the bottom side of the lower gun body 5. An electric wire 6 is provided on the bottom side of the handle 9. The limit member 11 is slidably connected to the spring groove, and the limit member 11 is located inside the limit groove 10.

[0024] Specifically, when in use, the slider 4 is moved downward, driving the connecting block 12 and the limit member 11 to move downward at the same time, so that the limit member 11 leaves the inside of the limit groove 10 and compresses the spring 13, and then the upper gun body 7 is rotated and adjusted to a suitable angle, and then the slider 4 is released, the spring 13 rebounds, driving the limit member 11 to move upward and enter the inside of the limit groove 10, and then re-limiting the upper gun body 7 to complete the adjustment of the welding gun angle, so that the welding gun can control whether the upper gun body 5 is fixed by controlling the slider 4, thereby achieving the effect of freely rotating the upper gun body 5, so that the welder can adjust the welding gun as needed to obtain the best accessibility and operating angle, thereby improving work comfort, and by adjusting the angle and position of the welding gun, the welder can better control the welding process, thereby improving welding quality and work efficiency.

[0025] Reference Figure 1 and Figure 3The top side of the upper gun body 7 is fixedly connected to a connecting tube 3, the top side of the connecting tube 3 is slidably connected to a mounting tube 2, the top side of the mounting tube 2 is fixedly connected to a welding head 1, the top side of the connecting tube 3 is fixedly connected to a plurality of disassembly control plates 15, the top side of the disassembly control plates 15 is fixedly connected to a bevel limiter 14, a plurality of limit holes 17 are provided on the outer wall of the mounting tube 2, a disassembly hole 16 is provided on the bottom side of the limit hole 17, the bevel limiter 14 is located inside the limit hole 17, and the disassembly control plate 15 is located inside the disassembly hole 16.

[0026] The cam 14 is then released from the slot 17 and the mounting tube 2 is no longer restricted by the cam 16 , so that the mounting tube 2 can be removed and the welding head 1 can be removed. The welding head 1 can then be taken out and the required welding head 1 can be put into the inner side of the mounting tube 2 .
