When the locking component abuts against the ground, it can provide a large frictional force to further improve the setting stability of the main body of the scaffold.

[0046] Please refer to the appendix Figure 5, the locking assembly includes a movable plate 901, an electric push rod 902, a sliding rod 903, a pressing plate 904 and a friction pad 905; the fixed end of the electric push rod 902 is fixedly installed on the top surface of the bottom plate 1, and the pushing end of the electric push rod 902 is vertically and fixedly connected to the middle of the movable plate 901; a pair of sliding rods 903 slidably penetrate through the bottom plate 1, the upper ends of the pair of sliding rods 903 are vertically and fixedly connected to both sides of the movable plate 901, and the lower ends of the pair of sliding rods 903 are vertically and fixedly connected to both sides of the pressing plate 904; a friction pad 905 is provided on the bottom surface of the pressing plate 904, so that the pressing plate 904 can be pressed against the ground through the friction pad 905.

[0047] Preferably, the electric push rod 902 can be a hydraulic or pneumatic telescopic rod. When the electric push rod 902 extends upward with its pushing end, it drives the movable plate 901, a pair of sliding rods 903 and the pressing plate 904 to move upward synchronously, so that the friction pad 905 is separated from the ground, facilitating the movement of the main body of the scaffold.

[0048] When the electric push rod 902 retracts its pushing end downward, it drives the movable plate 901, a pair of sliding rods 903 and the pressing plate 904 to move downward synchronously, so that the pressing friction pad 905 abuts against the ground. The friction pad 905 can be made of rubber material, which can generate a large frictional force to assist in braking the driving wheel 906 and ensure the static state of the main body of the scaffold.

[0049] Please refer to the appendix Figure 1 , a connecting frame 4 is provided between the bottom plate 1 and the working plate 2.
