[0002] A welding gun is a tool used for gas welding. It is shaped like a gun, with a nozzle at the front end, and emits a high-temperature flame as a heat source. It is flexible, convenient, and simple to use. A welding gun is one of the main equipment for hot air welding. It consists of a heating element, a nozzle, etc. According to its structure, there are gas welding guns, electric welding guns, fast welding guns, and automatic welding guns. A gas welding gun uses liquefied gas to be transmitted to the gun head through an explosion-proof high-pressure pipe, and then ignites it using an electronic ignition or a traditional ignition, and heats it to the required temperature for welding or baking. The gas sent in or out is adjusted by a switch, and its principle is the same as that of a household gas stove.
[0003] Usually, a flamethrower is connected to a gas tank during use. Since the gas is dangerous, the connection between the gas tank and the flamethrower requires extremely strong stability. When the gas in the gas tank is used up, the staff needs to replace the gas tank. Therefore, the gas tank and the flamethrower need to have the function of quick disassembly. Summary of the invention

The mechanism is detachably fixed to the welding gun body, and the locking mechanism consists of a locking disk and a clamping disk. The clamping disk is fixedly connected to the welding gun body by fixing bolts, and the locking disk is arranged on the outer side of the clamping disk and can be rotated on the clamping disk. Four clamping parts for locking are fixedly arranged on the clamping disk, and a clamping block for clamping is arranged on the clamping part. A locking block is fixedly arranged on the inner wall of the locking disk, and a slot one for the locking block to be clamped is provided between the four clamping parts, and a slot two for the clamping block to be clamped is provided on the inner wall of the locking disk.

DETAILED DESCRIPTION
[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 , Figure 3As shown, the welding gun with a locking mechanism comprises a welding gun body 1 and a gas tank 2, wherein the welding gun body 1 is provided with a gas pipe 3 for gas flow, the front end of the welding gun body 1 is provided with a spray gun head 4, the spray gun head 4 is fixedly mounted with a heat insulation pipe 5 for heat insulation, the heat insulation pipe 5 is fixedly connected to the spray gun head 4 by a fixing bolt, the upper end of the welding gun body 1 is provided with a control switch 6 for controlling the flow of gas in the gas pipe 3, the rear end of the welding gun body 1 is provided with an ignition mechanism 7 for ignition, the lower end of the welding gun body 1 is provided with a locking mechanism 8, and the gas tank 2 is detachably connected to the welding gun body through the locking mechanism 8. On the body 1, the locking mechanism 8 is composed of a locking disk 9 and a locking disk 10, the locking disk 10 is fixedly connected to the welding gun body 1 by fixing bolts, the locking disk 9 is arranged on the outer side of the locking disk 10, and can be rotated on the locking disk 10, the locking disk 10 is fixedly provided with four locking clamping parts 11, the clamping parts 11 are provided with a clamping block 12 for clamping, the inner wall of the locking disk 9 is fixedly provided with a locking block 13, a slot 14 for the locking block 13 to be clamped is provided between the four clamping parts 11, and a slot 2 15 for the clamping block 12 to be clamped is provided on the inner wall of the locking disk 9.
[0016] To further elaborate, when the gas tank 2 is locked (such as Figure 3 As shown in the figure, the locking block 13 is clamped at the position of the slot 14, and the clamping block 12 is clamped at the position of the slot 2 15, so that the installation space is tightened to fix the gas tank 2. When the gas tank 2 needs to be removed after use, the locking plate 9 (as shown in the figure) is rotated. Figure 3 As shown in the figure, the locking plate 9 is rotated clockwise to rotate the locking block 13, the locking block 13 leaves the slot 14, and the clamping block 12 leaves the slot 2 15, thereby releasing the fixation of the gas cylinder 2. When the gas cylinder 2 needs to be positioned, after the gas cylinder 2 is installed in the installation space, the locking plate 9 is rotated again (as shown in the figure). Figure 3 As shown, the gas cylinder 2 can be re-secured by rotating the locking disk 9 counterclockwise.
