[0030] The working principle is that when the detection device is used, the bolt to be detected is arranged on the top of the connecting box 1, the extrusion plate 4 is driven by the hydraulic device 3 to extrude the top of the bolt, and then the display screen 6 arranged on the surface of the control box 5 displays the force applied by the extrusion plate 4 on the surface of the bolt in real time. When the bolt deforms, the force applied at this time can be known through the display screen 6, and then the strength of the bolt can be known. When the protection device 7 is used, that is, when the extrusion plate 4 extrudes the bolt arranged on the top of the connecting box 1, the telescopic sleeve 701 is compressed, and the first spring 705 extrudes the rectangular frame 702 away from the extrusion plate 4. In this way, the rubber frame 703 fixed at the bottom of the rectangular frame 702 can be well extruded on the top of the connecting box 1, and the rubber frame 703 can well block the top of the connecting box 1 and the rectangular frame 702.

When the limiting device 8 is used, the second spring 807 pulls the rectangular block 808 towards the second threaded rod 802, so that the two rectangular blocks 808 can well extrude the bolt on both sides, and the bolt can be well limited on the top of the connecting box 1. Then the second threaded rod 802 is manually controlled to rotate, because the screw threads on the surface of the second threaded rod 802 are opposite to each other from the middle to both sides, so that the relative movement of the extrusion block 803 on the surface of the second threaded rod 802 can be well controlled, and the bolt can be well limited on the top of the connecting box 1 through the two extrusion blocks 803. When the extrusion block 803 extrudes the bolt, the arc surface opened on one side of the rubber plate 804 can well extrude the appearance of the bolt, because the bolt is cylindrical, so that the extrusion block 803 can well limit on one side of the bolt.
