A circular hole adapted to the limiting rod 30 is opened through the top surface of the top plate 21. The limiting rod 30 is fixedly connected to the pressure block 22 and is slidably connected to the circular hole. A threaded sleeve is also fixedly connected to the top surface of the top plate 21. The adjusting screw 31 is threadedly connected to the threaded sleeve. The lower end of the adjusting screw 31 is rotatably connected to the top surface of the pressure block 22. The extension rod 23 forms a rectangular rod structure. The top surface of the extension rod 23 is provided with a sliding groove adapted to the sliding rod 24. The sliding rod 24 is slidably arranged in the sliding groove.

[0029] The top plate 21 is rotated to be set on the top plate of the sliding rod 24, and the distance between the two top plates 21 can be adjusted. At the same time, the top plate 21 can be rotated so that the position where the pressing block 22 presses down and contacts the pad 11 can be changed, and the clamping position of the instrument can be flexibly adjusted. When welding, it is more flexible and convenient. By pulling the top plate 21, the sliding rod 24 is driven to slide in the sliding groove of the extension rod 23. The sliding rod 24 forms a rod body with a dovetail-shaped cross section. The sliding groove is adapted to the sliding rod 24. The adjusting screw 31 is rotated, and the adjusting screw 31 pushes the pressing block 22 to drive the limiting rod 30 to slide along the circular hole of the top plate 21, thereby adjusting the height of the pressing block 22. The distance between the pressing block 22 and the pad 11 can be adjusted according to the thickness of the instrument, further improving the adaptability.
