[0007] Further, the maintenance plate is designed in an arc structure.

[0008] Further, each of the maintenance plate and the connecting plate can be combined into a character-shaped structure.

[0009] Further, each of the maintenance plate and the connecting plate can be combined into a closed circular pipe-shaped structure.

[0010] Further, the sleeve ring is designed in a flat circular pipe structure.

[0011] Further, the other side of the maintenance plate is provided with a groove capable of accommodating the sleeve ring.

[0012] The utility model discloses the beneficial effects: through the sleeve ring and the positioning column combination of each group connecting plate and connecting sleeve between the setting connecting structure, can play the purpose of flexible adjustment angle to the connecting plate and connecting sleeve connected with each other, and further be favorable to the flexible convenient use according to the environment of construction site, and practicality is strong, through the series combination of connecting rope and sleeve ring, can play the reinforcing effect to the connecting plate and connecting sleeve connected with each other, and further be favorable to the stability of the connecting plate and connecting sleeve connection combination of improving.
