When the user judges whether it is qualified, the anti-skid push block 20 is pushed, so that the rectangular block 19 extrudes the guide rod 21. Under the cooperation of the first right-angle trapezoidal block 18 and the second right-angle trapezoidal block 24, the inclined rack 17 and the slide rod 16 are lowered, the distance between the second strong magnet 14 and the first strong magnet 13 becomes smaller, and the inclined rack 17 and the inclined clamping block 12 are separated. Under the action of the first spring 10, the extrusion block 7 and the T-shaped block 6 reset, which is convenient for detecting other gaps again. The whole process of the worker can be completed with one hand.
