[0023] like Figure 3 As shown, in this embodiment, the rotation positioning structure 3 is located in the V-shaped groove of the plastering board 1. The rotation positioning structure 3 includes a first side plate 301 and a second side plate 302 arranged side by side, the first side plate 301 and the second side plate 302 are both fixed on a connecting seat 303, the connecting seat 303 is fixed on the V-shaped groove wall of the plastering board 1, a rotating disk 304 and a pressing disk 305 are arranged between the first side plate 301 and the second side plate 302; the rotating disk 304 is connected to the handle 2, and the first annular positioning teeth 306 and the second annular positioning teeth 307 are respectively arranged on the relative matching surfaces between the first side plate 301 and the rotating disk 304, a first circular groove 308 is arranged at the middle position of the first annular positioning teeth 306 on the first side plate 301, and a first circular platform 309 is arranged at the middle position of the second annular positioning teeth 307 on the rotating disk 304, and the first circular platform 309 is embedded and matched with the first circular groove 308.

[0024] A second circular groove 310 and a second circular platform 311 are respectively provided on the relative mating surfaces between the turntable 304 and the pressure plate 305. The second circular groove 310 is coaxially arranged with the first circular platform 309, and the second circular groove 310 and the second circular platform 311 are embedded and matched. The pressure plate 305 is provided with a screw rod 312 on the side away from the turntable 304. The screw rod 312 is coaxially arranged with the second circular platform 311, and the screw rod 312 is connected to the reserved threaded hole on the second side plate 302. One end of the screw rod 312 is fixed to the pressure plate 305, and the other end is fixed to the hand wheel 313.
