[0104] When the handrail 1 and the display screen 21 need to be used:

[0105] The control button is started. First, the control button controls the second driving member 3323 to start and drive the second lead screw 3322 to rotate, thereby driving the second lead screw guide sleeve 3321 to move upward, so that the connecting rod assembly 331 is stretched, and in turn drives the second support 32 to move upward, so that the handrail 1 is lifted from the first position to the second position; secondly, the control button controls the first driving member 2233 to start and drive the first lead screw 2232 to rotate, thereby driving the first lead screw guide sleeve 2231 to move backward (i.e. moving towards the direction close to the handrail 1), so that the guide block 222 slides from the first guide groove 2211 to the second guide groove 2212 through the third guide groove 2213, and in turn drives the display screen 21 to flip and switch from the retracted state to the unfolded state.

[0106] It can be understood that, in the above operation process, after the handrail 1 reaches the second position, the control button can control the second driving member 3323 to stop or the second driving member 3323 to automatically stop; after the display screen 21 is in the unfolded state, the control button can control the first driving member 2233 to stop or the second driving member 3323 to automatically stop.

[0107] When the handrail 1 and the display screen 21 do not need to be used:

[0108] The starting control button first controls the first driving member 2233 to start and drive the first lead screw 2232 to rotate, so that the first lead screw guide sleeve 2231 moves forward (i.e., moves away from the handrail 1), so that the guide block 222 slides from the second guide groove 2212 to the first guide groove 2211 through the third guide groove 2213, and then drives the display screen 21 to flip and switch from the unfolded state to the recovered state; secondly, the control button controls the second driving member 3323 to start and drive the second lead screw 3322 to rotate, so that the second lead screw guide sleeve 3321 moves downward, so that the connecting rod assembly 331 can be retracted, and then drives the second support 32 to move downward, so that the handrail 1 is lowered from the second position to the first position.

[0109] It can be understood that, in the above operation process, after the display screen 21 is in the recovered state, the control button can control the first driving member 2233 to stop or the second driving member 3323 to automatically stop; after the handrail 1 reaches the first position, the control button can control the second driving member 3323 to stop or the second driving member 3323 to automatically stop.
