In addition, the second arc-shaped member 112 is connected to the first arc-shaped member 111, and the second arc-shaped member 111 The shaped member 112 rotates when the rotating member 11 is operated, and then drives the first arc-shaped member 111 to rotate.

The torsion providing part 20 is connected with the rotating part 10 . The torsion providing part 20 includes a fixing rod 21 , a shaft rod 22 and a torsion providing part 23 . The fixing rod 21 penetrates the mounting frame 13 and is opposite to the mounting frame 13 . An extension line 132 is orthogonal, the shaft rod 22 is disposed on the second arc-shaped member 112 , the two ends of the torsion providing member 23 connect the shaft rod 22 and the fixing rod 21 , and provide the rotation force of the rotating member 11 . Torsion, in one embodiment, the torsion providing member 23 is connected to one end of the shaft rod 22 as two connecting arms. In addition, the torque providing member 23 is provided with a linear guide hole 231 at the position where the fixing rod 21 is assembled. The linear guide hole 231 provides the fixing rod 21 to be disposed therein. The torque providing member 23 is relatively fixed when the rotating member 11 rotates. The rod 21 is displaced so that the fixing rod 21 can move in the linear guide hole 231, and the torsion providing member 23 abuts on the fixing rod 21 when the first arc-shaped member 111 and the second arc-shaped member 112 are fully expanded, The rotating member 11 is supported.
