There are four sets of moving mechanisms 4, which are symmetrically installed at the included angle on the top surface of the support plate 1. By installing four sets of moving mechanisms 4, the entire device can be moved easily. When the device is moved, the telescopic pump 402 is activated to push the moving wheels 403 down. After the moving wheels 403 contact the ground, the telescopic pump 402 continues to descend, which will generate a reaction force with the ground, thereby achieving the purpose of lifting and transferring the entire device, solving the problem that the original device was not easy to move.

[0027] In use, this invention first activates the telescopic pump 402, which extends and pushes the moving wheel 403 downwards. Once the moving wheel 403 contacts the ground, the continued descent of the telescopic pump 402 creates a reaction force with the ground, lifting the entire device. After this, the device can be moved to the appropriate position. Once moved, the telescopic pump 402 is activated to retract, causing the pad 404 to contact the ground and provide support. The first motor 304 is then activated, driving the rotating disk 303 via the first transmission rod 305. This allows for horizontal adjustment of the top welding unit. The second motor 307 rotates to drive... The rotation of the second motor 307 can adjust the relative angle between the first support arm 309 and the rotating disk 303. The retraction or extension of the hydraulic telescopic pump 313 can push the second support arm 311 to rotate on the surface of the rotating shaft 310, thereby adjusting the relative angle between the second support arm 311 and the first support arm 309, thus achieving the purpose of vertical adjustment of the welding unit. After completion, the third motor 315 can be turned on to drive the third transmission rod 317 to rotate, thereby causing the rotating block 316 to move and rotate on the surface of the third transmission rod 317, thus achieving the purpose of angle adjustment of the laser welding head 318, after which welding can be performed on the welding point.
