[0033] Reference Figure 1 A rotating structure in an embodiment of the first aspect of the utility model includes a limit member 103, a first turntable 110 and a second turntable 113. It can be understood that the first turntable 110 and the second turntable 113 are both rotatable components, and the first turntable 110 and the second turntable 113 rotate around the same rotation axis, and the rotation axis passes through the center of the first turntable 110 and the second turntable 113. A first limit block 111 is provided on the outer circumference of the first turntable 110, and a second limit block 114 is provided on the circumference of the second turntable 113. A movable groove 119 is defined on the second turntable 113, and a driving block 115 that can abut against the first limit block 111 is provided in the movable groove 119. A limit groove 105 is provided on the limit member 103. When the first turntable 110 rotates around the rotation axis, the first limit block 111 can move in the movable groove 119. When the first limit block 111 abuts against the driving block 115, the second turntable 113 can be driven to rotate around the rotation axis, and the second limit block 114 can be moved in the limit groove 105. The sum of the rotation angles of the first turntable 110 and the second turntable 113 along the rotation axis is greater than 360°, so as to increase the rotation angle and eliminate the rotation dead angle.

[0034] It should be noted that, for the convenience of description and understanding, in the present application, the direction around the rotation axis of the first turntable 110 and the second turntable 113 is referred to as the circumferential direction C.

[0035] Reference Figure 2, a mounting seat 106 is also provided. It can be understood that the first rotating disk 110 and the second rotating disk 113 rotate on the mounting seat 106, and the first limiting block 111 is located on the radial outer periphery of the first rotating disk 110 and extends in a direction away from the rotation axis. The second rotating disk 113 is located on the outer periphery of the first rotating disk 110 away from the rotation axis, and the movable groove 119 is around the radial outer periphery of the first rotating disk 110. It can be understood that the movable groove 119 is surrounded by the radial outer wall of the first rotating disk 110 and the radial inner wall of the second rotating disk 113, and the limiting groove 105 is located on the second rotating disk 113, and the second limiting block 114 is located on the outer periphery of the second rotating disk 113 away from the rotation axis, and the limiting groove 105 is around the radial outer periphery of the second rotating disk 113.

[0036] Further, along the circumferential direction C, the widths of the first limiting block 111 , the second limiting block 114 and the driving block 115 are smaller than the length of the limiting groove 105 . It should be noted that the first limit block 111, the second limit block 114 and the driving block 115 have a certain width in the direction of the circumferential direction C. Therefore, when the first limit block 111 moves along the movable groove 119, the rotation angle of the first turntable 110 relative to the second turntable 113 is less than 360°. At the same time, the second limit block 114 slides on the limit groove 105, so that the second turntable 113 can rotate within a certain angle. The rotation angle of the first turntable 110 is the sum of the movement angle of the first limit block 111 in the movable groove 119 and the movement angle of the second limit block 114 in the limit groove 105. Therefore, the width of the first limit block 111, the second limit block 114 and the driving block 115 in the direction of the circumferential direction C is less than the length of the limit groove 105, so that the rotation angle of the first turntable 110 can be greater than 360°.

[0037] Reference Figure 3 The stopper 103 covers the second rotating disk 113, the stopper 103 is provided with a cavity 104, the second rotating disk 113 is located in the cavity 104, the radial outer wall of the second rotating disk 113 abuts against the inner wall of the cavity 104, so that the second rotating disk 113 can be rotated around the rotation axis through the outer wall guide. Further, a mounting seat 106 and a connecting rod 107 are also provided, the stopper 103 is fixedly mounted on the mounting seat 106, the first rotating disk 110 and the second rotating disk 113 are located between the stopper 103 and the mounting seat 106, the connecting rod 107 is rotatably connected to the mounting seat 106, and the first rotating disk 110 is connected to the connecting rod 107.

[0038] Reference Figure 2, the connecting rod 107 passes through the mounting seat 106 and the first rotating disk 110, the first rotating disk 110 has a slotted hole 112, the connecting rod 107 is inserted into the slotted hole 112, and the radial outer wall of the connecting rod 107 is provided with a matching surface 118, and the matching surface 118 matches with the plane inner wall of the slotted hole 112. It can be understood that the slotted hole 112 has a straight side wall surface, and the matching surface 118 is also a plane. Through the matching surface 118 and the plane inner wall of the slotted hole 112, when the connecting rod 107 rotates, it can drive the first rotating disk 110 to rotate, thereby limiting the rotation angle of the connecting rod 107.

[0039] Further, refer to Figure 5 The end of the connecting rod 107 is provided with a screwed nut 108, and the nut 108 is pressed against the first rotating disk 110 along the direction of the rotation axis.

Furthermore, a spring sheet 109 is provided between the nut 108 and the first rotating disk 110, so that the nut 108 and the first rotating disk 110 are elastically pressed against each other, thereby increasing the pre-tightening force of the nut 108 and enhancing the anti-loosening effect. Furthermore, the connecting rod 107 is provided with a protrusion 116 extending in the circumferential direction, the outer diameter of the protrusion 116 is larger than the outer diameter of the screw connection with the nut 108, and a damping plate 117 is provided between the end of the protrusion 116 in the axial direction and the mounting seat 106. It can be understood that when the nut 108 is tightened on the connecting rod 107, the end of the protrusion 116 can press against the bottom wall of the mounting seat 106. At this time, the damping plate 117 is provided on the bottom wall of the mounting seat 106, which can increase the rotation damping of the connecting rod 107 on the mounting seat 106, so as to facilitate the adjustment of the rotation angle, and it is not easy to automatically deflect after the angle is adjusted. It can be understood that the damping plate 117 can be made of flexible high-damping materials such as silicone, rubber or polyurethane, or materials such as polyoxymethylene and resin.
