The outer side of the hydraulic cylinder 5 is fixed with an arc fixing seat 6. The top of the arc fixing seat 6 is fixedly connected to the bottom of the laser welding box 1, so that the hydraulic cylinder 5 can be supported. Both ends of the rectangular moving seat 7 are rotatably connected to a first inclined rotating plate 9 through pins. One end of the first inclined rotating plate 9 away from the rectangular moving seat 7 is rotatably connected to a horizontal moving column 10 through a pin. The top of the rectangular moving seat 7 is slidably connected to a top fixing block 8. The top of the top fixing block 8 is fixedly connected to the laser welding box 1;

[0025] A dovetail slider is fixed to the top of the rectangular moving seat 7, and a dovetail chute is provided inside the top fixing block 8. The rectangular moving seat 7 and the top fixing block 8 are slidably connected through the cooperation of the dovetail slider and the dovetail chute, enabling the rectangular moving seat 7 to slide at the bottom of the top fixing block 8, thereby guiding the moving track of the rectangular moving seat 7;

[0026] A transverse optical rod 11 is slidably connected inside the transverse moving column 10. Transverse fixing plates 12 are fixed to both ends of the transverse optical rod 11, and the top of the transverse fixing plates 12 is fixedly connected to the laser welding box 1, enabling the transverse moving column 10 to slide outside the transverse optical rod 11. The setting of the transverse fixing plates 12 enables the transverse optical rod 11 to be supported;

[0027] Here, the operation of the hydraulic cylinder 5 enables the rectangular moving seat 7 to move, enabling the top fixing block 8 to slide at the bottom of the rectangular moving seat 7. The movement of the rectangular moving seat 7 enables the transverse moving column 10 to be outside the transverse optical rod 11 through the first obliquely rotating plate 9, thereby enabling the distance between the two transverse moving columns 10 to be adjusted;

[0028] The lifting mechanism further includes a second obliquely rotating plate 13. The second obliquely rotating plate 13 is rotatably connected to both sides of the transverse moving column 10 through a pin shaft.

The bottom of the bottom anti-skid pad 17 is provided with anti-skid grooves. The rubber material allows the bottom anti-skid pad 17 to better fit the ground. The setting of the anti-skid grooves can improve the anti-skid performance of the bottom anti-skid pad 17.

[0033] Here, the movement of the two transverse movable columns 10, through the setting of the second oblique rotating plate 13, enables the bottom support seat 3 to be vertically lifted and lowered, and the vertical optical rod 16 to slide vertically inside the vertical circular tube 15, so that the bottom support seat 3 can move toward the ground, and the universal wheel can be lifted, so that the laser welding box 1 can be supported to prevent the displacement of the laser welding box 1.
