In addition, a spring 21 is connected between the guide rod 1 and the guide sleeve 7, and the two ends of the spring 21 are respectively fixedly connected to the guide sleeve 7 and the guide rod 1. The first motor 10 drives the cam 11 to rotate, and the cam 11 can contact the contact plate 8, allowing the guide rod 1 to move upward, and the height adjustment can be completed.
