When the pressing plate 58 moves downward, the connecting column 41 and the second rack 44 move downward, so that the second rack 44 drives the second transmission gear 48 to rotate. The second transmission gear 48 cannot drive the rotating shaft 47 and the threaded rod 33 to rotate through the second one-way bearing 49;

[0038] When the pressure plate 58 is released, the release button 4 is reset. At this time, the connecting spring 42 pushes the connecting column 41 to drive the second rack 44 to move upward, so that the second rack 44 drives the second transmission gear 48 to drive the second one-way bearing 49 and the second bevel gear 51 to rotate, so that the second bevel gear 51 drives the limit block 54 and the spline member 56 as well as the spline groove 55 and the guide rod 57 to rotate through the third bevel gear 52, so that the guide rod 57 drives the threaded rod 33 to rotate through the pulley 63, so that the threaded rod 33 drives the second piston column 32 to move upward, so that the liquid inside the liquid sac 29 is sucked into the second piston chamber 31 through the connecting pipe 30, so that the supporting spring 28 pushes the sealing block 27 to move upward, so that the bottom end of the sealing block 27 moves out of the fixing tube 8, so that the through hole 26 is connected to the air cavity and the inside of the suction cup 7 with the external environment through the fixing tube 8, so that the suction force inside the suction cup 7 disappears, the limit on the positioning sleeve 62 is released, and then the positioning sleeve 62 and the test head 6 are moved;

[0039] During this process, the threaded rod 33 rotates through the first bevel gear 35 to drive the connecting rod 34, the first one-way bearing 36 and the first transmission gear 37 to rotate idly. When the connecting rod 34 drives the threaded rod 33 to rotate through the first bevel gear 35, the threaded rod 33 drives the guide rod 57, the spline groove 55, the spline member 56 and the limit block 54 through the pulley 63, as well as the third bevel gear 52 and the second bevel gear 51 to drive the rotating shaft 47 to drive the second one-way bearing 49 and the second transmission gear 48 to rotate idly.
