When working, the two groups of clamps 22 slidably connected on the support seat 20 are used to clamp and limit the front and rear sides of the light strip. Before welding, the right side of the light strip will first abut against the top block 41. The trapezoidal design of the top block 41 can separate the wiring so that the wiring can be aligned with the welding points on the light strip. When welding a light strip of larger specifications, first release the fixation on the top of the clamp 22, and then pull one of the groups of clamps 22 The bottom end of the splint 22 is connected to the fixed rod 24 through the connecting column 23, and the fixed rod 24 is rotatably connected to the connecting rod 25. The fixed rod 24 will pull the connecting rod 25 to move, and the connecting rod 25 is rotatably connected to the rotating disk 26, and the rotating disk 26 will rotate a certain angle. Since the two sets of connecting rods 25 are rotatably connected to the rotating disk 26, when one set of splints 22 is pulled to move, the other set of splints 22 will also move the same distance, wherein the top part of the connecting column 23 is slidably connected to the inside of the U-shaped groove 43, and the U-shaped groove 43 can limit the moving distance of the connecting column 23 to prevent the connecting column 23 from moving too far.
