[0002] In the modern society with the ever-increasing progress of science and technology, steel structures have been applied in various locations and places that are familiar to people. Among them, the most well-known application place of steel structures is in various construction projects. In addition, in order to ensure the tightness of steel structures, welding or connection between steel structures is often required before using them. Since the strength of the joints needs to be inspected to ensure that the project meets the requirements, it is necessary to use a tightening detection device to perform strength detection of the steel structure joints.

[0003] After searching, it is found that the utility model patent with the announcement number CN214794209U discloses a fastening detection device for steel structure engineering, including a test device body, the test device body includes the test device body, a cylinder is fixedly installed on the inner side of the test device body, and a pressure test block is fixedly installed on the bottom end of the cylinder, a clamping mechanism is inserted into the interior of the test device body, and the clamping mechanism includes a threaded sleeve, and a threaded sleeve is inserted into the interior of the test device body; this patent sets a clamping plate, and when the threaded sleeve rotates inside the test device body through a hollow round block, the threaded sleeve engages and rotates with the threaded column at this moment, because the slider set on the outer side of the connecting rod is inserted into the threaded column, the slider plays a limiting role on the threaded column, so that the threaded column drives the clamping plate downward through the fixed block, and because the outer shape of the clamping plate is an arc-shaped structure, the steel is prevented from being offset, and the steel is stably clamped, thereby improving the detection efficiency of the steel.

[0004] In the above patented technical solution, a clamping plate is provided to prevent the steel from deflecting and stably clamp the steel, thereby improving the inspection efficiency of the steel. However, the above patented technical solution still has the following shortcomings when used:

[0005] 1. The position of the main body of the test device set in the above patented technical solution is fixed. When the steel structure has multiple joints, the above patented technical solution can only be tested by the test personnel manually adjusting the position of the steel structure one by one to make the test position directly below the main body of the test device. The operation is complicated, which brings inconvenience to the test personnel and affects the efficiency of steel structure detection;

[0006] 2. The pressure test block and cylinder provided in the above-mentioned patent technical solution are fixedly installed with the test device body, which is inconvenient to disassemble and assemble, resulting in inconvenience in maintaining the pressure test block. After the pressure test block is used for a long time, the detection accuracy of the pressure test block will decrease, resulting in inaccurate steel structure tightening detection data.
