[0030] The utility model connects the lifting component 6 and the linkage component 7, and after the lifting component 6 is started, the lifting component 6 drives the test component 5 to move upward through the linkage component 7, and then the lifting component 6 drives the linkage component 7 to move left, so that the linkage component 7 is separated.

[0040] The motor 603 is started, and the motor 603 drives the second screw 602 to rotate. The second screw 602 drives the movable plate 605 to move upward. The movable plate 605 drives the linkage assembly 7 and the sliding frame 502 to move, so that the sliding frame 502 and the detection hammer 503 move to the upper end of the column 501.

[0041] In one embodiment, for the above-mentioned round rod 701, the linkage assembly 7 includes a round rod 701 and a side plate 702, the round rod 701 is slidably connected to the inside of the movable plate 605, the outer surface of the round rod 701 is fixedly connected with a ring 703, the outer surface of the ring 703 is fixedly connected with a spring 704, the end of the round rod 701 is rotatably connected with a rotating wheel 705, the side plate 702 is fixedly connected to the outer surface of the sliding frame 502, the outer surface of the side plate 702 is provided with an arc groove 706, the outer surface of the side plate 702 is rotatably connected with a rotating plate 707, the interior of the rotating plate 707 is fixedly connected with a limiting rod 708, the limiting rod 708 is slidably connected to the arc groove 706, and the interior of the rotating plate 707 is fixedly connected with a torsion spring 709.

[0042] The movable plate 605 drives the round rod 701 and the rotating wheel 705 to move upward, and the rotating wheel 705 pushes the rotating plate 707, so that the limiting rod 708 on the rotating plate 707 is pressed against the end of the arc groove 706, thereby driving the side plate 702 and the sliding frame 502 to move upward through the cooperation of the limiting rod 708 and the arc groove 706.
