[0031] The lifting assembly 401 includes two fixed plates 4011 fixedly connected to the L-shaped plate 302. The fixed plate 4011 located at the bottom is made of an electromagnet. When the direction of the current on the electromagnet changes, the magnetic field will also change. This is a prior art. For example, a magnetically controlled switch is set at the power supply, and it corresponds to the fixed bar 4011. A guide rod 4012 is fixedly connected between the two fixed plates 4011.
