[0027] Scale lines 308 are provided on the outer circumference of the mounting rod 305 to judge the up and down sliding degree of the mounting rod 305 and thus reflect the flatness of the steel structure.

[0028] When detecting the scratch resistance characteristics of the steel structure, the mounting rod 305 is fixed to the bracket 301, and a fastening ring 310 is threadedly connected to the threaded column 311.

The bracket 301 is pushed to make the scratch test head 313 slide on the steel structure, and the scratch on the surface of the steel structure is observed to judge its anti-scratch characteristics.

[0033] In summary: In the embodiment of the present utility model, the motor 201 drives the screw 202 to rotate. The two ends of the screw 202 have opposite threads, thereby driving the slider 205 and the clamping members 203 symmetrically arranged above the slider 205 to slide in the box at the same time, realizing the stable clamping of the steel structure to be detected. The upper ends of the symmetrically arranged clamping members 203 are connected to the detection mechanism 3.

After pushing the bracket 301, the scale line 308 on the mounting rod 305 is observed, and whether the mounting rod 305 slides up and down is used to judge the flatness of the steel structure. The smaller the scale change, the better the flatness of the steel structure. When it is necessary to detect the anti-scratch characteristics of the steel structure, after replacing the scratch test head 313, the mounting rod 305 and the bracket 301 can be fixed by using the fastening ring 310 and the threaded column 311, and then the scratch test can be carried out by sliding. The operation is simple and convenient, and the practicability is strong.
