Since the four swing arm brackets 22 are arranged in parallel and form a parallelogram with the support frame 2 and the handrail frame 21, when the swing arm bracket 22 rotates, it will drive the other swing arm brackets 22 to rotate, thereby driving the handrail frame 21 to move up and down, so as to quickly realize the function of adjusting the height of the seat plate 38;

[0058] The controller 24 drives the electric push rod 27 to adjust the height of the seat plate 38, and at the same time controls the start of the motor 315, and drives the second bevel gear 318 to rotate through the output shaft of the motor 315, drives the first bevel gear 317 to rotate through the second bevel gear 318, drives the reciprocating screw rod 316 to rotate through the first bevel gear 317, and drives the lifting rod 311 to reciprocate and lift through the reciprocating screw rod 316, and the lifting plate and the seat plate 38 and the seat plate frame 31 The movement state is consistent, thereby providing support for the bottom of the seat plate 38 and the seat plate frame 31, preventing the center of gravity from changing during the lifting process and the shifting machine from tilting; and the lifting rod 311 and the sliding sleeve cooperate to provide support for the seat plate frame 31, and protect the seat plate frame 31;

[0059] When the foot pedal 14 needs to be adjusted, by pressing the limit column 152, the spring 155 is compressed, and the limit column 152 is compressed into the sliding cavity 154, the footrest frame 15 can be pulled, and the footrest frame 15 slides on the sliding rod 151. By moving the footrest frame 15 to a suitable position and stopping the movement, the limit column 152 is reset under the action of the spring 155, and the limit column 152 is moved to the corresponding limit hole 153, and the footrest frame 15 is fixed and limited, thereby realizing the function of facilitating the adjustment of the position of the foot pedal 14.
