At this time, the supporting assembly 3 is fixed by the fixing assembly 5 to achieve the function of fixing the supporting plate 2, which has the function of facilitating quick folding and opening. Example 2

[0025] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the wedging component 4 includes a fixed wedge 401, a slope is arranged on the upper left of the fixed wedge 401, the fixed wedge 401 and the left side of the supporting plate 2 are movably penetrated, a connecting piece 402 is fixedly connected below the fixed wedge 401, an elastic piece 403 is elastically connected between the connecting piece 402 and the left side of the supporting plate 2, and the elastic piece 403 will exert elastic force to push the connecting piece 402 to the left in a normal state to reset the fixed wedge 401, an elastic component 6 is arranged on the left side of the wedging component 4, and the elastic component 6 includes a limiting piece 601, and the limiting piece 601 is fixedly connected to the left side of the supporting plate 2, A sliding rod 602 is movably penetrated above the limiting plate 601, and a top plate 603 is fixedly connected above the sliding rod 602.

When the guard plate 2 is opened, the spring 604 will apply a pulling force to pull the top plate 603 downward, and the top plate 603 will drive the sliding rod 602 to slide downward. At this time, the top block 605 on the sliding rod 602 will press against the inclined surface on the fixed wedge 401, pushing the fixed wedge 401 to the right, and the fixed wedge 401 will extend from the right side of the guard plate 2. When the support plate 2 is propped up, the fixed wedge 401 will be nailed into the inner wall of the foundation pit to achieve the effect of stable support.
