[0031] When the C-shaped plate 61 moves toward the direction close to the box door 2, the movement of the C-shaped plate 61 drives the tooth plate 2 76 to move, the movement of the tooth plate 2 76 drives the tooth block 3 77 to move, and the movement of the tooth block 3 77 drives the tooth block 1 73 to move. Because the tooth block 1 73 is engaged with the tooth block 3 77, the movement of the tooth block 1 73 drives the turntable 72 to rotate under the action of the tooth block 3 77. At the same time, the rotation of the turntable 72 drives the tooth block 1 73 to rotate, and the rotation of the tooth block 1 73 drives the tooth plate 2 76 to move, and the movement of the tooth plate 2 76 drives the protective plate 78 to move until it moves to the surface of the welding box 1, thereby preventing the welding box 1 from colliding with external objects when moving, thereby preventing the inside of the welding box 1 from being damaged. The equipment is damaged, thereby extending the overall service life of the equipment and reducing the maintenance frequency and cost. At the same time, the movement of the protective plate 78 drives the telescopic elastic rod 2 79 to move, and the movement of the telescopic elastic rod 2 79 drives the support plate 710 to move. When the support plate 710 continues to move until it is out of the limit of the bottom plate 63, the telescopic elastic rod 2 79 restores its deformation and pushes the support plate 710 to move away from the protective plate 78, avoiding the welding box 1 from tipping over due to external force, and then causing damage to the equipment inside the welding box 1. It can ensure the stability of the equipment in various environments, make it adapt to more complex working scenes, and facilitate the development of welding operations.
