[0002] When pouring shear walls, waterstop screws are often used to secure the formwork and control the thickness of the concrete pour. Waterstop screws consist of a screw, a waterstop plate, and a spacer. Both the welding of the waterstop screws and the spacer plate must comply with certain specifications. Some construction companies require single-sided welding of waterstops, while other construction sites with stricter requirements may perform double-sided welding. However, when welding on one side, the automatic welder may expose some holes, leading to quality defects. Clearly, single-sided welding cannot meet the market demand in the context of the increasing number of high-rise buildings.

[0004] 1. It can only play a fixing effect, and cannot adjust the welding position of the water stop on the screw, or the adjustment method is relatively inconvenient, resulting in limitations in welding and inability to achieve multi-specification welding;

[0005] 2. After welding on one side, it is inconvenient to repair the welding on the other side. The screw needs to be pulled out and turned around before being fixed, which wastes welding time and causes low welding efficiency. Utility Model Content

[0013] As a preferred technical solution of the present invention, the outer side of the telescopic rod is inserted with a hand-tightening stud, and the hand-tightening stud is threadably matched with a plurality of screw holes provided on the inner side of the telescopic rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:
