[0012] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0013] like Figure 1 As shown, the embodiment of this utility model includes an upper clamp 1 and a lower clamp 2, connected by a connecting arc plate 3, which together form a cylindrical structure. The upper clamp 1 is a circular ring structure, divided in the middle into a first retaining ring 1-1 and a second retaining ring 1-2. For quick installation, the ends of the first retaining ring 1-1 and the second retaining ring 1-2 are connected by pins. The lower clamp 2 is a circular ring structure, divided in the middle into a third retaining ring 2-1 and a fourth retaining ring 2-2. For quick installation, the ends of the third retaining ring 2-1 and the fourth retaining ring 2-2 are also connected by pins. Four support plates 4 are distributed radially outward on the outer circumference of the upper clamp 1 and are hinged to the upper clamp 1. The hinges are horizontally oriented, and the support plates 4 can rotate up and down around the hinges. The four support plates 4 are evenly and symmetrically distributed on the circumference of the upper clamp 1 and are staggered from the connection parts of the first retaining ring 1-1 and the second retaining ring 1-2.

[0014] As Figure 2 shown, the bottom of the support plate 4 is provided with a limiting plate 4-1, and a plurality of connecting holes 4-2, preferably seven, are arranged on the limiting plate 4-1. As Figure 1 shown, on the outer side of the connecting arc plate 3, the corresponding position of the support plate 4 turned downward is provided with a groove 3-2, and the support plate 4 turned downward to the minimum angle can be embedded in the groove 3-2, which is convenient for storage. The groove 3-2 is also provided with a connecting head 3-3, the lower end of the connecting rod 3-1 is hinged on the connecting head 3-3, and the upper end of the connecting rod 3-1 is hinged on the connecting hole 4-2. By changing the hinging of the connecting rod 3-1 on different connecting holes 4-2, the corresponding support plate 4 can be at different inclination angles, which can change the support angle. In order to quickly install, the connecting mode of the two ends of the connecting rod 3-1 is pin connection.
