[0028] In order to facilitate the adjustment of the horizontal angle of the welding gun during cutting, a swivel opening 211 is provided in the middle of the upper surface of the pulley 21, and the rotating shaft 221 is located in the swivel opening 211. The rotating shaft 221 is rotatably connected to the swivel opening 211, and a locking structure 222 is provided on the outer wall of the rotating shaft 221. The locking structure 222 includes a movable shaft 2221 that is plugged into the outer wall of the rotating shaft 221, and a grip 2222 that is arranged at the end of the movable shaft 2221 away from the rotating shaft 221. A reset spring 2223 is provided at the end of the movable shaft 2221 close to the rotating shaft 221. The movable shaft 2221 is connected to the inner wall of the rotating shaft 221 through the reset spring 2223. A first pointer 2224 is provided in the grip 2222. A horizontal scale is provided on the upper surface of the swivel opening 211. The rotating shaft 221 is driven to rotate in the swivel opening 211 by pulling the grip 2222, and the first pointer 2224 is provided. 2224 and the horizontal scale read the horizontal rotation angle, so as to facilitate the adjustment of the horizontal angle of the welding gun during cutting. In order to avoid accidental rotation during cutting, the outer wall of the turning mouth 211 is provided with a tooth groove 212, and the locking structure 222 is provided with teeth correspondingly near the outer wall of the turning mouth 211. The locking structure 222 is engaged with the outer wall of the turning mouth 211 through the teeth and the tooth groove 212. The grip 2222 is pulled outward by overcoming the elastic force of the reset spring 2223, so that the grip 2222 is separated from the outer wall of the turning mouth 211, and the rotating shaft 221 is driven to rotate in the turning mouth 211 through the grip 2222. After the horizontal angle is adjusted, the grip 2222 is released. Under the elastic force of the reset spring 2223, the grip 2222 is close to the outer wall of the turning mouth 211, and the teeth of the grip 2222 are engaged in the tooth groove 212, so as to avoid accidental rotation.

[0029] Furthermore, in order to facilitate the adjustment of the height of the welding gun, a lifting shaft 224 is provided in the middle of the bottom of the top head 223, and limiting rods 226 are provided at both ends of the bottom of the top head 223. A vertical scale is provided on the surface of the limiting rod 226. The bottoms of the lifting shaft 224 and the limiting rod 226 are plugged and matched with the top of the rotating shaft 221. The top head 223 is movably connected with the rotating shaft 221 up and down through the lifting shaft 224, and then plugged and matched with the rotating shaft 221 through the limiting rod 226 to prevent the top head 223 from rotating when it moves up and down, and the vertical scale exposed on the top of the rotating shaft 221 by the limiting rod 226 can read the height value of the welding gun when it moves up and down;

[0030] Furthermore, in order to prevent the top head 223 from changing in height relative to the rotating shaft 221 when performing along-track moving cutting, a latch 2225 is provided at one end of the movable shaft 2221 away from the grip 2222, and the latch 2225 passes through the rotating shaft 221. A slot is provided on the outer wall of the lifting shaft 224, and the end of the latch 2225 contacts the slot. The latch 2225 and the outer wall of the lifting shaft 224 are engaged with each other through the slot. When the horizontal angle and height adjustment of the welding gun are completed, the grip 2222 is released, and under the elastic force of the reset spring 2223, the grip 2222 is engaged with the outer wall of the rotating port 211, and the latch 2225 is inserted into the slot and engaged with the outer wall of the lifting shaft 224, thereby preventing the top head 223 from changing in height relative to the rotating shaft 221, and ensuring that the height of the welding gun remains unchanged when performing along-track moving cutting;

[0031] In addition, in order to facilitate the welding gun to approach the workpiece to be cut, the top head 223 is provided with a through hole 225, and the outer wall of the top head 223 is provided with an inclined scale, the extension plate 231 is rotatably connected to the through hole 225, and a movable pin 234 is provided on the extension plate 231 near the through hole 225, and a second pointer 235 is provided on the movable pin 234. By rotating the extension plate 231 in the vertical plane, the clamp 233 is tilted and approaches the workpiece to be cut, and the inclination angle of the extension plate 231 can be known through the second pointer 235 and the inclined scale, and the clamp 233 is connected to a connecting plate 232 at one end of the extension plate 231, and the connecting plate 232 is plug-fitted with the extension plate 231, and a screw shaft 236 is rotatably connected to the connecting plate 232, and one end of the screw shaft 236 is threadedly connected to the extension plate 231. By plug-fitting and threaded connection, the screw shaft 236 can be rotated to adjust the distance between the clamp 233 and the extension plate 231, so as to facilitate the welding gun to further approach the workpiece to be cut;

[0032] It is worth noting that the slide rail 1 can be made according to the shape of the cutting product. For example, if the cutting seam is linear, the track is made linear; if the cutting seam is circular, the track is made circular. That is to say, the slide rail 1 can be designed according to the shape of the cutting seam, and handles 213 for pulling the turning port 211 to move are symmetrically provided at both ends of the turning port 211.
