When the lower button of the bottom plate assembly 40 is pressed (SB5 is equal to 1), the controller controls the third electric push rod 42 to shorten (the relay KA5 is equal to 1, and the relay KA6 is equal to 0), and pulls the whole bottom plate assembly 40 to lower downwards; when the lifting button (SB6 ═ 1) of the floor assembly 40 is pressed, the controller controls the third electric push rod 42 to extend (the relay KA5 ═ 0, and the relay KA6 ═ 1), and pushes the whole floor assembly 40 to lift upwards.

When each control action is stopped, the controller reads and records the position information of the electric push rod and covers the last recorded position information.
