[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] I. This utility model, through its designed testing components, can handle three testing scenarios. When it is necessary to connect the top of the test handrail to a tension / compression timer, first place the moving plate in the desired position, insert the bolt into the corresponding screw hole, and rotate the nut to fix it on the outer surface of the bolt. After fixing the moving plate in the desired position, tie the strap and fix it inside the tension / compression timer, and then fix the strap inside the U-shaped groove. Finally, place the tension / compression timer inside the first connecting hole for testing. When it is not necessary to connect the top of the test handrail to a tension / compression timer, pass the strap through the U-shaped groove and the second connecting hole, and fix both ends of the strap to the test handrail. With the assistance of a level, help the user adjust the length of the strap so that the test handrails on both sides are horizontal, and then use the tension / compression timer for testing. When it is necessary to fix the test handrail to the middle of the bottom of the fixture body, fix the strap inside the second connecting hole located in the middle, and fix the test handrail in the desired position with the strap, and then use the tension / compression timer for testing. This solution can test handrails of different widths, improving the flexibility of the fixture.

[0018] Based on the first beneficial effect, when the strap needs to be fixed to the clamp body with the help of the limiting component, first apply a pulling force to the guide buckle, the spring is in a compressed state, pass one end of the strap through the connecting groove, release the force applied to the guide buckle, and under the elastic force of the spring, the pressing plate restricts the strap inside the connecting frame, then wrap the strap around and fix it to the outside of the fixing post, and finally pass one end of the strap through the corresponding limiting hole and tie a knot to fix it. This solution can effectively store the strap in the required position and make it convenient to use the strap. Attached Figure Description
