[0033] A slide groove 7 is formed on the inner wall of the groove 2 , and sliders 8 are fixedly connected to the top and bottom of the movable plate 3 . The sliders 8 are slidably connected in the inner cavity of the slide groove 7 to limit the moving direction of the movable plate 3 .

[0034] The inner cavity of the C-shaped clamping plate 6 is provided with limiting holes 9 , and the limiting holes 9 are distributed in a plurality of groups of linear arrays, and the limiting holes 9 of the C-shaped clamping plate 6 at different positions have the same size.

[0035] In the embodiment of the utility model, the L-shaped frame 1 is placed at the four corners of the frame body, and the extended C-shaped clamps 6 are matched in pairs to achieve mutual fixation between the four groups of L-shaped frames 1. In the fixing process, a limiter is generally used, and the limiter passes through the limit holes 9 between the front and rear groups of C-shaped clamps 6 to achieve the fixation of the C-shaped clamps 6 and the fixation between the L-shaped frames 1. Multiple groups of linear array limit holes 9 will enhance the fixing effect and improve the stability of the prefabricated frame.

[0036] When the length of the prefabricated frame needs to be changed, the movable plate 3 is dragged to move the movable plate 3 out of the inner cavity of the groove 2, thereby realizing the movement of the C-shaped clamp 6, realizing the change of the size of the final prefabricated frame, meeting the needs of frame size changes in different situations, and improving compatibility. The top and bottom of the movable plate 3 are fixedly connected with a slider 8, and the slider 8 can slide in the inner cavity of the slide groove 7, thereby limiting the moving direction of the movable plate 3 and improving the stability of the movable plate 3.

The outer ring sliding sleeve of the telescopic rod 10 is provided with a spring 11. One side of the spring 11 is fixedly connected to one side of the C-shaped clamp plate 6. A first fixed seat 12 is fixedly connected to one side of the L-shaped frame 1. A first rotating plate 13 is hinged to one side of the first fixed seat 12. A telescopic hole 14 is opened in the inner cavity of the first rotating plate 13. The telescopic rod 10 is inserted into the inner cavity of the telescopic hole 14. A hook 15 is fixedly connected to one side of the first rotating plate 13. The hook 15 is fixedly connected to one side of the spring 11.

[0039] One side of the C-shaped clamp 6 is fixedly connected to a second fixed seat 16, and one side of the second fixed seat 16 is hinged to a second rotating plate 17.

The first rotating plate 13 and the second rotating plate 17 are connected by a hinge. When the first rotating plate 13 is unfolded or folded with the movement of the movable plate 3, the spring 11 is driven to stretch or squeeze, thereby generating a force on the spring 11. One side of the spring 11 is fixedly connected to the C-shaped clamp 6, and the other side is fixedly connected to the L-shaped frame 1 through the hook 15.
