The front and rear sides of the limiting bracket 11 are movably connected with the inner side of the fixed frame 1.

[0023] The operator first pulls the pulling plate 7. At this time, the pulling plate 7 will drive the movable plate 6 to move backward. At this time, the movable plate 6 will exert a squeezing force on the first spring 5. At this time, the movable plate 6 will cause the inclined plate 8 to rotate and pull the connecting block 9. At this time, the connecting block 9 will drive the clamping plate 10 to move stably in opposite directions under the limiting action of the limiting bracket 11. At this time, the clamping plate 10 will leave the inside of the mounting plate 3 and release the clamping effect on the mounting plate 3. At this time, the operator can quickly disassemble the top plate 2.

[0024] Refer to Figures 1 to 5 , the bottom of the fixed frame 1 is movably connected with a bottom plate 12. The bottom of the bottom plate 12 is fixedly installed with an inserting plate 13.

[0025] As a technical optimization scheme of the present invention, due to the design of the inserting plate 13, the operator can insert the inserting plate 13 into the soil, and at the same time, it can play a good role in stabilizing the bottom plate 12.

[0026] Reference Figure 2 、 Figure 3 and Figure 5 On both the left and right sides of the top of the bottom plate 12, limiting plates 14 are fixedly installed, and a moving plate 15 is movably connected to the inner sides of the limiting plates 14.

[0027] As a technical optimization scheme of the present utility model, due to the design of the limiting plate 14, the limiting plate 14 will have a good limiting effect on the moving plate 15.

[0028] Reference Figure 2 、 Figure 3 and Figure 5 The other end of the moving plate 15 extends to the outside of the fixing frame 1, and the outer surface of the moving plate 15 is movably connected to the inside of the fixing frame 1.

[0029] As a technical optimization scheme of the present utility model, due to the design of the moving plate 15, the moving plate 15 will have a good clamping effect on the fixing frame 1.

[0030] Reference Figure 2 and Figure 3 A pulling block 16 is fixedly installed on the top of the moving plate 15, and the shape of the pulling block 16 is rectangular.

[0031] As a technical optimization scheme of the present utility model, when an operator pulls the pulling block 16, at this time the pulling block 16 will drive the moving plate 15 to move in an opposite direction.

[0032] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 On the rear ends of both the left and right sides of the fixing frame 1, baffles 17 are hinged, a bolt 18 is threadedly sleeved on the left side of the baffle 17, the other end of the bolt 18 extends into the inside of the moving plate 15, and the outer surface of the bolt 18 is threadedly sleeved with the inside of the moving plate 15.

[0033] As a technical optimization scheme of the present utility model, due to the design of the bolt 18, the bolt 18 will fix the baffle 17 and the moving plate 15 together.

[0034] Reference Figures 2 to 5 A rectangular plate 19 is fixedly installed on the top of the bottom plate 12, and second springs 20 are fixedly connected to both the left and right sides of the rectangular plate 19, and the other ends of the second springs 20 are fixedly connected to the inner sides of the moving plate 15.

[0035] As a technical optimization scheme of the present utility model, due to the design of the second springs 20, the second springs 20 will enable the moving plate 15 to stably perform a clamping operation inside the fixing frame 1.

[0036] The working principle and usage process of the present utility model:

[0037] When the operator needs to disassemble the top plate 2, first pull the pull plate 7. The pull plate 7 will move the movable plate 6 backward at the same time. At this time, the movable plate 6 will apply a squeezing force to the first spring 5. Then the movable plate 6 will cause the inclined plate 8 to rotate and pull the connecting block 9. At this time, the connecting block 9 will drive the clamping plate 10 to move smoothly in opposite directions under the limiting action of the limiting frame 11. At this time, the clamping plate 10 will leave the inside of the mounting plate 3 and release the fixing effect on the mounting plate 3. At this time, the operator can quickly disassemble the top plate 2.

[0038] When the operator needs to change the height of the fixing frame 1, rotate the bolt 18 at this time. The bolt 18 will leave the inside of the moving plate 15 and release the fixing effect between the baffle 17 and the moving plate 15. At this time, the operator pulls the pull block 16. The pull block 16 will drive the moving plate 15 to move in opposite directions under the limiting action of the limiting plate 14. At this time, the moving plate 15 will apply a squeezing force to the second spring 20 and release the clamping effect on the fixing frame 1. At this time, the operator can change the fixing frame 1.
