A connecting frame 308 is rotatably connected between the inner ends of the connecting rods 307; by rotating the knob 304, the rotating shaft 303 rotates, the rotation of the rotating shaft 303 causes the movable head 306 to rotate, thereby driving the connecting rod 307 and the connecting frame 308 to rotate, and further causing the two rotating shafts 303 and the two second bevel gears 305 to rotate simultaneously. The rotation of the second bevel gear 305 drives the first bevel gear 301 to rotate, so as to rotate the bidirectional screw 2, which is convenient for the two lifting frames 5 to move simultaneously.
