[0040] In a further embodiment, the carrying plate 4 is slidably connected in the sliding sleeve 6 , and the outer wall of the sliding sleeve 6 is slidably connected to the pulling plate 7 .

[0041] Specifically, the traction plate 7 can limit the sliding sleeve 6 to a certain extent, thereby ensuring its stability when moving upward.

[0042] In a further embodiment, a telescopic spring 501 is provided inside the rubber block 5 , and the telescopic springs 501 are distributed at equal intervals between the bearing plate 4 and the sliding sleeve 6 .

[0043] Preferably, the preferred number of rubber blocks 5 is 2 to 4 groups, and a telescopic guide rod is provided inside the telescopic spring 501, and the preferred number of telescopic springs 501 is 4 to 7 groups.

[0044] In a further embodiment, a ball 9 is installed at the bottom of the moving block 8 , and the bottom of the ball 9 contacts the top of the sliding sleeve 6 .

[0045] Specifically, the balls 9 can support the moving block 8 when it moves, thereby facilitating the reduction of the supporting pressure borne by the first lead screw 10 and the second lead screw 11 , thereby facilitating the improvement of the rationality of the device structure.

[0046] In a further embodiment, the motor 12 , the first lead screw 10 , the belt transmission structure 13 and the second lead screw 11 constitute a rotating structure, and the first lead screw 10 and the second lead screw 11 are both connected to the base 1 through a mounting bracket 14 .

[0047] Specifically, the motor 12 drives the first screw 10 to rotate, and the rotating first screw 10 will drive the second screw 11 to rotate through the belt transmission structure 13, so that the moving block 8 can drive the detection device 26 to move left and right along the first screw 10 and the second screw 11 to perform detection work.
