The ends of the plurality of insertion rods 310 away from the fixing ring 308 are fixedly connected with an adjustment plate 311. The cross-section of the adjustment plate 311 is a right-angled trapezoid. The adjustment plate 311 corresponds to the oblique waist side of the top plate 305. The end of the protective cover 301 away from the handle 302 is fitted with the fixing ring 308. By setting the adjustment structure 3, the protective cover 301 can effectively prevent external objects or impurities in the environment from entering the welding head 5, avoiding damage or wear caused thereby, and can reduce pollution and dust accumulation on the surface of the welding head 5, thereby increasing the service life of the welding head 5. In addition, the personnel can conveniently disassemble and assemble the protective cover 301, so that the operator can operate the welding head 5 according to actual needs. The protective cover 301 can be installed at any time. A plurality of positioning rods 313 are slidably penetrated on the side of the fixing ring 308. One end of the positioning rod 313 is fixedly connected to the protective cover 301. When installing the protective cover 301, the plurality of positioning rods 313 fixed on one end of the protective cover 301 are first inserted into the fixing ring 308, and then the protective cover 301 can be positioned so that the insertion hole 307 and the insertion rod 310 can be quickly aligned, thereby achieving the effect of improving the installation speed of the protective cover 301. The oblique waist side of the top plate 305 is rotatably connected with a pulley 314. The arc surface of the pulley 314 abuts against the adjustment plate 311.

The end of the plug rod 310 away from the adjustment plate 311 is in a conical structure. By setting one end of the plug rod 310 as a conical structure, the volume of the conical structure is small, so that the plug rod 310 can be easily inserted into the inside of the jack 307. The outer wall of the adjustment ring 303 is provided with a plurality of anti-skid grooves 316, which are evenly distributed on the outer wall of the adjustment ring 303. The personnel can rotate the adjustment ring 303 with the help of the anti-skid grooves 316, so as to achieve the effect of conveniently controlling the adjustment ring 303.

[0031] Detailed explanation of usage: When a welding gun is needed to perform welding operations on an object, a person can hold the handle 1 to move the welding gun to the position of the object to be welded, and then press the switch button 2 to make the welding head 5 weld the object. When the welding gun is used and the welding head 5 needs to be protected, the person can first move the handle 302 to drive the protective cover 301, and insert the positioning rod 313 on the protective cover 301 into the fixing ring 308 until one end of the protective cover 301 fits with the fixing ring 308. At this time, the socket 307 and the insertion rod 310 will be aligned. When the socket 307 and the insertion rod 310 are aligned, the adjustment ring 303 is rotated with the help of the anti-slip groove 316 to make the adjustment ring 303 move along the protective cover 301. The outer wall moves toward the direction close to the slip ring 304, the adjusting ring 303 squeezes the slip ring 304, the slip ring 304 drives a plurality of top plates 305, and the plurality of top plates 305 drive the pulley 314 to squeeze a plurality of adjusting plates 311 at the same time, so that the adjusting plate 311 drives the plug rod 310 to move toward the direction close to the plug hole 307, until the plug rod 310 is inserted into the plug hole 307, and the installation and fixation of the protective cover 301 can be completed. When the personnel need to use the welding head 5, the protective cover 301 needs to be disassembled. At this time, the adjusting ring 303 is first rotated in the opposite direction with the help of the anti-slip groove 316 to move the adjusting ring 303 away from the slip ring 304. When the adjusting ring 303 and the slip ring 3 304, the top plate 305 is driven by the sliding ring 304 to drive the pulley 314 to separate from the adjusting plate 311. After the pulley 314 is separated from the adjusting plate 311, the spring 312 controls the plunger 310 to quickly move away from the fixing ring 308 until the plunger 310 is separated from the socket 307 on the partition 306, thereby achieving the effect of conveniently disassembling the protective cover 301. When the plunger 310 is separated from the socket 307 on the partition 306, the personnel moves the handle 302 to drive the protective cover 301, so that the protective cover 301 drives the positioning rod 313 to separate from the fixing ring 308, and the removal of the protective cover 301 is completed. The sliding friction between the top plate 305 and the adjustment plate 311 is converted into rolling friction, which reduces the friction between the top plate 305 and the adjustment plate 311, thereby making the process of the top plate 305 squeezing and driving the adjustment plate 311 smoother. In addition, the adjustment ring 303 squeezes the slip ring 304, so that the slip ring 304 moves along the outer wall of the protective cover 301. The guide rod 315 can guide and position the slip ring 304, thereby preventing the slip ring 304 from causing rotational deviation during the movement of the top plate 305. Finally, by setting one end of the insertion rod 310 to a conical structure with a smaller volume, the insertion rod 310 can be easily inserted into the inside of the socket 307.
