Since the outer edge of the first bevel gear 53 and the outer edge of the second bevel gear 55 are meshed with each other, when the first bevel gear 53 rotates, the second bevel gear 55 is driven to rotate at the same time. The rotation of the second bevel gear 55 drives the main pulley 54 to rotate, and the rotation of the main pulley 54 drives the two belt strips 56 to rotate. The rotation of the two belt strips 56 drives the two secondary pulleys 57 to rotate, and the rotation of the secondary pulley 57 drives the telescopic rod 58 Rotation, through the telescopic rod 58, the lifting rod 13 is driven to rotate along the inner wall of the positioning sleeve 12. Since the outer edge of the lifting rod 13 is provided with a spiral pattern, the inner wall of the positioning sleeve 12 is provided with a spiral groove adapted thereto, by controlling the lifting rod 13 to rotate clockwise, it will move upward along the inner wall of the positioning sleeve 12 and stretch the length of the telescopic rod 58.
