On opposite sides of the longitudinal axis guiding slide rail (601), third lead screws (60201) are rotatably arranged through opposite ends of the transverse axis guiding slide rail (501) along its length direction in a threaded manner. One end of each third lead screw (60201) is coaxially provided with a synchronous pulley (60202). Opposite ends of the synchronous belt (60203) are respectively sleeved on the corresponding synchronous pulleys (60202). The third driving motor is arranged on the longitudinal axis guiding slide rail (601) for driving any one of the third lead screws (60201) to rotate.
