[0007] As a further solution of the utility model: the cross-sectional shapes of the two arc-shaped connecting frames are symmetrical to each other, and the edges of the arc-shaped connecting frames are hook-shaped structures, which are convenient for clamping the retaining rope.

[0008] As a further solution of the utility model: both ends of the arc-shaped auxiliary support frame have a bending structure toward the arc-shaped connecting frame, so as to shorten the distance between the arc-shaped connecting frame and the edge of the arc-shaped auxiliary support frame.

[0009] As a further solution of the present utility model: The distance between the arc-shaped connection frame and the edge of the arc-shaped auxiliary support frame is less than the diameter of the rope stopper, so as to facilitate clamping the air film fabric.

[0010] As a further solution of the present utility model: The cross-sectional shape of the arc-shaped limiting groove is an open sphere, and the upper and lower ends of the cross-sectional shape of the arc-shaped connecting plate are both spherical and are clamped in the arc-shaped limiting groove, which is convenient for the connection and combination of the frame structure.

[0011] As a further solution of the present utility model: The arc-shaped connecting plate is made of an elastic material.

[0012] The advantages of the present utility model compared with the prior art are as follows: This patent adds an arc-shaped connection frame and an arc-shaped auxiliary support frame structure, which can limit the edge of the air film fabric through which the rope stopper passes, and is used to connect and tighten the air film fabric. Moreover, the structure is simple, with fewer components and is convenient for installation. Description of the Drawings
