[0032] A groove is provided on the inner surface of the skeleton 300, and the inner support rod fixing block 100 is hollow and has a buckle provided on the lower edge, and the buckle is buckled in the groove. The inner support rod fixing block 100 is a convex structure when viewed from the side, which is wide at one end near the buckle and narrow at the other end. The wide part is used to install the rotating part of one end of the inner support rod 200, and the narrow part has no cover on it to facilitate the rotation of the inner support rod 200.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, as a further solution of the utility model: a groove is provided on the frame 300, the inner support rod fixing block 100 is installed in the groove, and the inner support rod fixing block 100 is provided with a buckle portion.

[0034] The inner support rod 200 includes a first rotating part 210 and a second rotating part 220. The groove is arranged on the back of the frame 300, and the groove is divided into two layers, the first rotating part 210 and the buckle part are arranged on the longitudinal edge of the lower layer. The inner support rod fixing block 100 is in contact with the first rotating part 210, and the inner support rod fixing block 100 plays the role of limiting the first rotating part 210. Installing the inner support rod fixing block 100 in the groove is conducive to accommodating the frame 300.

[0035] like Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 As shown, as a further solution of the utility model: the inner support rod fixing block 100 includes a first fixing member 110, a fixing block body 120 and a locking member 140 arranged in sequence; a first step 11a is provided in the extension direction of the end of the first fixing member 110; and a second step 141 is provided in the extension direction of the end of the locking member 140.

[0036] The first step 11a and the second step 141 are provided to prevent the inner support rod fixing block 100 from falling off.
