[0035] The top of detection frame 11 is provided with reciprocating assembly, reciprocating assembly includes bidirectional threaded rod 12, threaded block 13, first bevel gear 16 and second bevel gear 15, bidirectional threaded rod 12 is arranged in the inside of connecting frame 6, two threaded blocks 13 are symmetrically sleeved on both ends of bidirectional threaded rod 12, two second bevel gears 15 are symmetrically sleeved on the middle part of bidirectional threaded rod 12, first bevel gear 16 is arranged on the back of second bevel gear 15.

[0036] Please refer to Figure 3 andFigure 4 Two ends of the bidirectional threaded rod 12 are rotatably connected with the inner walls of the two sides of the connecting frame 6, and the interior of the threaded block 13 is provided with a threaded hole matched with the bidirectional threaded rod 12, and the two end arms of the bidirectional threaded rod 12 are rotatably connected with the interiors of the two threaded blocks 13.

[0037] When the bidirectional threaded rod 12 rotates, the two threaded blocks 13 on the two sides can be driven to move inwardly and contract or move outwardly and expand.

[0038] Please refer to Figure 3 and Figure 4 The opposite sides of the two second bevel gears 15 are provided with baffles 14, the two baffles 14 are symmetrically sleeved on the middle part of the bidirectional threaded rod 12, and the baffles 14 are fixedly installed in the interior of the connecting frame 6.

[0039] Under the action of the baffles 14, the two second bevel gears 15 can be protected, so that the threaded blocks 13 do not contact the second bevel gears 15 when they contract, and the situation of extrusion deformation does not occur.

[0040] Please refer to Figure 3 and Figure 4 The outer wall of the first bevel gear 16 is engaged with the outer wall of the second bevel gear 15, the back surface of the first bevel gear 16 is fixedly connected with a driving shaft 18, and one end arm of the driving shaft 18 is rotatably connected with the back inner wall of the connecting frame 6.

[0041] The first bevel gear 16 is fixedly installed on the back surfaces of the two second bevel gears 15 under the action of the driving shaft 18, the first bevel gear 16 is a half-fan gear here, and the teeth are evenly arranged on one side of the first bevel gear 16 at 180 degrees, so that the first bevel gear 16 can alternately engage with the two second bevel gears 15 when it rotates, so that the bidirectional threaded rod 12 can be driven to rotate forwardly and reversely.
