[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-4 As shown, the utility model is provided with two main support tubes 1 and two auxiliary support tubes 2. The auxiliary support tubes 2 are behind the main support tubes 1 on the corresponding side. The main support tubes 1 and the auxiliary support tubes 2 on the same side are combined together by a number of evenly distributed connecting rods 3 between the main support tubes 1 and the auxiliary support tubes 2. The main support tubes 1 and the auxiliary support tubes 2 on both sides are connected by the connecting rods 3 to form two groups of racks, which are connected by a folding structure 8 between the two groups of racks. The lower ends of the main support tubes 1 and the auxiliary support tubes 2 are provided with rotatable control ring blocks 4, and the lower ends of the inner parts of the main support tubes 1 and the auxiliary support tubes 2 are provided with adjusting struts 5. The adjusting struts 5 and the inner parts of the control ring blocks 4 are threadedly connected together. In order to be able to drive the adjusting struts 5 to move up and down by rotating the control ring blocks 4, so as to facilitate the two groups of racks to adjust the lower ends of each support tube according to the terrain, the utility model is provided with main limit strips 13 and auxiliary limit strips 14 on both sides of the lower ends inside the main support tubes 1 and the auxiliary support tubes 2.

[0023] The utility model provides limiting grooves 15 on both sides of each adjusting strut 5. In this way, when the control ring block 4 rotates, the adjusting strut 5 will not rotate with the rotation of the control ring block 4. Under the action of the thread, the adjusting strut 5 can move up and down along the main limiting strip 13 or the auxiliary limiting strip 14 through the limiting groove 15 to form a limiting structure 6, ensuring that the lower end of the support pipe can contact the ground and ensure the stability of the scaffolding itself. A strap 7 is arranged between the main support pipes 1, and buckles 9 are installed on both sides of the strap 7. The strap 7 is placed between the two groups of shelves through the buckles 9 to ensure the stability of the two groups of shelves. A lifting plate 10 is arranged on the upper side of the main support pipe 1, and a telescopic cylinder 11 is installed at the lower end of the lifting plate 10. The telescopic cylinder 11 supports the upper side of the strap 7 by telescoping to realize the up and down movement of the lifting plate 10. The lower ends of the adjusting struts 5 are fixedly connected with hemispherical anti-sliding blocks 12.

[0024] The utility model is provided with collars 16 on the upper and lower ends of the outer part of the main support tube 1, and the collars 16 are connected to the outer part of the main support tube 1 by rotation. A vertical main connecting tube 17 is arranged between the main support tubes 1, and auxiliary connecting tubes 18 are arranged above and below the main connecting tube 17, and the auxiliary connecting tube 18 is connected to the main connecting tube 17 by rotation. The upper and lower collars 16 and the main connecting tube 17 on one side are connected together by a main connecting rod 19, and the upper and lower collars 16 and the upper and lower auxiliary connecting tubes 18 on the other side are connected together by an auxiliary connecting rod 20, so as to facilitate the folding of the shelves on both sides, and facilitate assembly and storage. Insertion rods 21 are installed on the front, back and both sides of the lower end of the lifting plate 10, and the insertion rods 21 are respectively inserted into the upper sides of the main support tube 1 and the auxiliary support tube 2, so as to facilitate the positioning function of the lifting plate 10 when it moves up and down.

[0025] When the utility model is implemented, the two sets of shelves are first placed on the ground where they need to be built, and the control ring block 4 at the lower end of each support pipe is rotated according to the condition of the ground. Under the limiting effect of the limit structure 6, the adjustment support rod 5 at the lower end of the corresponding support pipe is lifted and lowered, and supported on the ground, ensuring that the lower end of each support pipe has a support point, and the buckle 9 on the strap 7 is matched to the appropriate connecting rod 3. The worker stands on the lifting plate 10 to carry out construction, and the telescopic cylinder 11 installed at the lower end of the lifting plate 10 is used to support the upper end of the strap 7 to achieve lifting and lowering adjustment. When use is completed, the strap 7 and the lifting plate 10 are removed, and the shelves formed on both sides are folded up through the folding structure 8.

[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
