The working principle of the present invention is as follows:

Expand the work: When the operating platform is in a retracted state, drop the A or B pedals on the ground, then unfold the A and B pedals, and tighten the pins on the hinge components to achieve self-locking of the hinge components. Tightly, so that the A pedal and the B pedal are fixedly connected; unfold the support leg members on the A pedal and B pedal. When the support leg member is unfolded to the set position, the telescopic member is also in a fully extended state, and the entire operating platform can be turned over and straightened. , construction workers can step on the pedals to carry out construction operations; during the construction process, if the length of the pedals needs to be lengthened, the A pedal or B pedal can be fixed, and then the other unfixed pedal can be pulled outward to achieve the length of the pedals. The length of the pedals can also be increased by pulling the A pedal and the B pedal outward at the same time.

Folding work: Turn over the entire operating platform, and the pedal surface is attached to the ground. At this time, the safety buckle slides down along the support member under the action of its own gravity and breaks away from the connection point; the support leg member of the A pedal or B pedal can be A downward external force is applied to the connection between the A transverse fastener and the B transverse fastener. The A transverse fastener and the B transverse fastener swing downward. The A and B support legs shrink inward. Align the A and B support legs to the bottom of the pedal respectively. Place the edges on both sides; perform the same operation for the other pedal. After packing up the supporting leg components, release the self-locking of the hinge structure, that is, pull out the pin; then merge the bottoms of the A pedal and the B pedal facing each other, and fold them The job is done. In order to facilitate transportation, handles can be provided on the outer walls of the pedals, or additional binding pieces can be added for binding and transportation.

If the length of the pedal is increasing when folded, the fixed plate must be fully inserted into the pedal that is connected to it before shrinking.

After the invention is folded, the length becomes half of the original, and the volume is greatly reduced compared to the unfolded state; the structural shape is a rectangular structure, and it is very convenient to carry on the shoulder or by hand.
