[0027] When parking the bicycle: the user operates the control switch 7 to energize the electromagnet 27, and the PLC controller controls the electromagnet 27 to energize for a period of time (e.g., one minute). After the electromagnet 27 is energized, the rack clamping block 26 is sucked up. The user pushes the electric bicycle to make the front tire contact with the push block 25, and continues to push the electric bicycle forward, so that the push block 25 and the spur rack 24 move backward. When the push block 25 moves backward, the clamping arms 22 on both sides are pulled by the connecting rod 251 to slide along the linear slide rail 212 and approach each other until the clamping arms 22 clamp the electric bicycle. The front wheel rim of the bicycle is automatically powered off after the electromagnet 27 is energized for a period of time, and the rack block 26 automatically falls down and engages with the tooth surface of the spur rack 24; the user starts the lifting drive mechanism 3 by operating the control switch 7, the drive motor 31 drives the transmission screw 32 to rotate, the transmission screw 32 drives the wheel rim clamping mechanism 2 to rise, and the wheel rim clamping mechanism 2 pulls the front wheel of the electric bicycle to lift upward until the wheel rim clamping mechanism 2 moves to the position of the upper limit switch 5 and the drive motor 31 stops working. At this time, the indicator light 6 lights up to remind the user to park in place;

[0028] When picking up the bicycle: the user starts the lifting drive mechanism 3 by operating the control switch 7, and the driving motor 31 drives the transmission screw 32 to rotate to make the wheel clamping mechanism 2 descend. The wheel clamping mechanism 2 stops descending after putting the wheel on the ground. Then the user operates the control switch 7 to energize the electromagnet 27, so that the electromagnet 27 re-sucks up the rack clamping block 26. The user pushes the electric bicycle backward so that the front wheel pushes the clamping arm 22 to open and complete the bicycle picking up. After being energized for a period of time, the electromagnet 27 is automatically powered off and restored to the original state.
