[0042] The use process of a new type of automatic lifting platform provided by the utility model is as follows: the user pulls the handle 6 to pull the device to the vicinity of the operating table, and then energizes the motor 21 to rotate, and the output end of the motor 21 drives the worm 22 to rotate. Since the bottom of the worm 22 is meshed and connected with the worm wheel 23, the rotation of the worm 22 drives the worm wheel 23 to rotate, and then drives the rotating rod 24 and the cam 25 to rotate, so that the cam 25 can resist the brake block 18 to descend, and stretch the four springs 17, so that the brake block 18 is fully in contact with the ground, which enhances the friction and ensures the stability of the device; the nurse hangs the infusion bag on the outside of the hook 16, and then energizes the motor 8 to rotate, and the output end of the motor 8 drives the first bevel gear 9 to rotate Since one side of the first bevel gear 9 is meshedly connected with the second bevel gear 10, the rotation of the first bevel gear 9 drives the second bevel gear 10 to rotate, and then drives the screw 11 to rotate. Since the outer side of the screw 11 is threadedly connected with the screw sleeve 12, the rotation of the screw 11 drives the screw sleeve 12 and the slider 13 to slide and rise and fall on the inner side of the limiting sleeve 14, and then drives the fixed shaft 15 and the hook 16 to rise and fall. The movement characteristics of the screw 11 driving the screw sleeve 12 to rise and fall are precise positioning and low noise. In summary, the utility model can provide stability, improve safety, achieve precise control, facilitate operation, and extend the service life of the equipment. These benefits jointly promote the smooth progress of arthroscopic surgery and the improvement of surgical quality.
