[0028] In this embodiment, when welding is performed, the welding clamp 3 is manually pulled, and the welding clamp 3 pulls the cable 2 to make the cable 2 spread out from the winding wheel 6, and the cable 2 can be pulled to a required length, which is convenient for the welding work of the welding machine body 1. After the welding is completed, the welding clamp 3 is moved close to the winding wheel 6, that is, the cable 2 is in a relaxed state. At this time, with the cooperation of the reset component 7, the rotating shaft 5 is driven to rotate in the opposite direction, and the rotating shaft 5 drives the winding wheel 6 to rotate in the opposite direction, so that the cable 2 can be wound up, thereby facilitating the automatic winding of the cable 2, facilitating the operation and use of the welding machine body 1, and improving the use efficiency of the welding machine body 1.

[0029] In a further embodiment, Figure 2-3 As shown, the reset assembly 7 includes a housing 71 fixedly disposed on one side of the support plate 4 and rotatably connected to the shaft 5. A coil spring 72 fixed to the shaft 5 is fixed to the inner wall of the housing 71. A through hole 8 for the cable 2 to pass through is opened inside the shaft 5.

[0030] First, the cable 2 is connected to the welding machine body 1, and then the cable 2 is inserted from one end of the through hole 8 on the rotating shaft 5, and then passed out from the other end, and then wound on the reel 6 after passing out, so that the initial state of the cable 2 is the reeling state. When the welding machine body 1 is used, the welding clamp 3 is manually pulled, and the welding clamp 3 pulls the movement of the cable 2, and the cable 2 drives the rotation of the reel 6 to spread the cable 2. At the same time, the rotation of the reel 6 drives the rotation of the rotating shaft 5, and the rotating shaft 5 drives the movement of the coil spring 72, so that the coil spring 72 is in a contracted state. When the cable 2 is pulled to the required length, the welding work can be carried out. When the welding is completed, the welding clamp 3 is moved close to the reel 6, so that the cable 2 is in a relaxed state, and then under the elastic action of the reel 72, the rotating shaft 5 is driven to rotate in the opposite direction, and the rotating shaft 5 drives the reel 6 to rotate in the opposite direction. The cable 2 is reeled in the reverse rotation of the reel 6, which can facilitate the automatic reeling of the cable 2, facilitate the use of the welding machine body 1, and improve the use efficiency of the welding machine body 1.

[0032] The moving wheels arranged at the bottom of the moving seat 9 can be used to push the welding machine body 1 to move. When the welding machine body 1 encounters a bumpy road surface during movement and causes vibration, the welding machine body 1 drives the movement of the vertical plate 11, and the vertical plate 11 drives the movement of the sliding component 12 and the buffer component 13, so that the welding machine body 1 can be buffered and protected, the bump vibration damage of the welding machine body 1 is reduced, and the service life of the welding machine body 1 is increased.

[0033] In a further embodiment, Figure 4 As shown, the sliding assembly 12 includes a push rod 121 hingedly arranged at the bottom end of the vertical plate 11, a slider 122 is hingedly arranged at the bottom end of the push rod 121, a slide groove 123 for the slider 122 to slide is provided at the top end of the moving seat 9, and the buffer assembly 13 includes a damper 131 fixedly arranged between the slider 122 and the slide groove 123, and a spring 132 is provided on the outer wall of the damper 131.

[0034] When the welding machine body 1 vibrates during movement, the welding machine body 1 drives the vertical plate 11 to move, the vertical plate 11 drives the push rod 121 to move, the push rod 121 drives the slider 122 to move, and the slider 122 squeezes the damper 131 and the spring 132 during movement. The damper 131 and the spring 132 cooperate to provide buffer protection for the welding machine body 1, reduce vibration damage to the welding machine body 1, and increase the service life of the welding machine body 1.

[0035] The implementation principle of a thyristor electric welding machine in the embodiment of the present application is as follows: when the welding machine body 1 is used for welding, the welding machine body 1 is first pushed to a specified position. When the welding machine body 1 encounters a bumpy road surface and vibrates during movement, the welding machine body 1 drives the vertical plate 11 to move, the vertical plate 11 drives the push rod 121 to move outward, the push rod 121 drives the slider 122 to move outward, and the slider 122 squeezes the damper 131 and the spring 132 during movement, thereby providing buffer protection for the welding machine body 1, reducing the bump and vibration damage of the welding machine body 1, and increasing the service life of the welding machine body 1. During use, the welding clamp 3 is manually pulled , the welding clamp 3 drives the cable 2 to spread out from the winding wheel 6, and the winding wheel 6 rotates under the pulling of the cable 2, thereby driving the rotation of the rotating shaft 5. The winding spring 72 is contracted during the rotation of the rotating shaft 5. When the cable 2 is pulled to an appropriate length, welding work can be carried out. When welding is completed, the welding clamp 3 is moved closer to the winding wheel 6 to relax the cable 2. Then, under the elastic action of the winding spring 72, the rotating shaft 5 is driven to rotate in the opposite direction. The rotating shaft 5 drives the winding wheel 6 to rotate in the opposite direction. The cable 2 can be wound up during the rotation of the winding wheel 6, thereby facilitating the automatic winding of the cable 2, facilitating the use of the welding machine body 1, and improving the use efficiency of the welding machine body 1.
