Detailed Implementation

[0049] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0050] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0051] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0053] To allow the two connecting members of the connecting mechanism to flexibly occupy multiple angular positions, in a first aspect, one embodiment of this application provides a connecting mechanism, see [reference]. Figure 1 As shown, it includes: a first gear 6, which is provided with a first connecting member 3; and a second gear 7, which meshes with the first gear 6; the second gear 7 is provided with a second connecting member 4, so that when the first gear or the second gear rotates, it drives the first connecting member and the second connecting member to rotate.

[0054] The first gear can drive the first connecting member to rotate, and the second gear can drive the second connecting member to rotate. The connection method between the first gear and the first connecting member, and the connection method between the second gear and the second connecting member are not limited here.

[0055] Optionally, the first gear 6 is fixedly connected to the first connecting member 3; the second gear 7 is fixedly connected to the second connecting member 4. It is understood that the fixed connection can be a detachable fixed connection or a snap-fit, or it can be a connection method such as welding or riveting, and there is no limitation here.

[0056] See Figure 1 As shown, the first gear 6 and the second gear 7 mesh, so that when either gear 6 or 7 rotates, the other gear rotates synchronously. When the first gear 6 is fixedly connected to the first connecting member 3, and the second gear 7 is fixedly connected to the second connecting member 4, the first connecting member 3 and the second connecting member 4 also rotate synchronously with the synchronous rotation of the first and second gears. Due to the meshing of the first and second gears, when one of them does not rotate, both gears will remain fixed in a certain position, and thus the first connecting member 3 and the second connecting member 4 will also remain fixed. This allows the first connecting member 3 and the second connecting member 4 to remain stationary in a certain position, and further, they can flexibly be in multiple angular positions and remain stationary. When the first connecting member 3 is connected to the first rotating shaft and the second connecting member 4 is connected to the second rotating shaft, the first rotating shaft can be flexibly in multiple angular positions relative to the second rotating shaft and remain stationary, thus achieving the purpose of flexibly placing the two connecting members of the connecting mechanism in multiple angular positions between 0° and 180°.

[0057] By engaging the first gear and the second gear, the first connecting member and the second connecting member are driven to rotate. Thus, the first connecting member and the second connecting member can drive the two connecting members of the connecting mechanism to move synchronously. As the two gears mesh and rotate, the included angle between the first connecting member and the second connecting member can stay at any position between 0° and 180°, thereby allowing the two connecting members of the connecting mechanism to flexibly be in multiple angular positions.

[0058] See Figure 2-4As shown, in another embodiment of this application, the connecting mechanism further includes: a housing 5; the first gear and the second gear are disposed inside the housing 5, the housing is provided with a first hole 8 corresponding to the position of the first through hole, and the housing is provided with a second hole 9 corresponding to the position of the second through hole.

[0059] Optionally, see Figure 2 and 3 As shown, the first gear has a first through hole (not shown in the figure) through the rotation center of the first gear, and the first connecting member is fixed in the first through hole; the second gear has a second through hole (not shown in the figure) through the rotation center of the second gear, and the second connecting member is fixed in the second through hole.

[0060] Optionally, the first gear and the second gear are circular structures. The first connecting member is fixed at the rotation center of the first gear, and the second connecting member is fixed at the rotation center of the second gear. This allows the first connecting member, the second connecting member, the first gear, and the second gear to rotate at the same central angle, making it easier to control the included angle between the first connecting member and the second connecting member at a specified angle, which is beneficial for the position control of the first connecting member and the second connecting member.

[0061] Optionally, see Figure 3 As shown, the two ends of the first connector extend from the two ends of the first through hole; the two ends of the second connector extend from the two ends of the second through hole; both the first connector and the second connector are connectors; the two ends of the connector are respectively provided with a first fixed connection end and a second fixed connection end.

[0062] The first connector is disposed within the first through hole and extends from both ends of the first through hole, and the second connector is disposed within the second through hole and extends from both ends of the second through hole. This allows the main bodies to which the first and second connectors are respectively connected to to be simultaneously expanded or retracted.

[0063] See Figure 5 As shown, the connector includes: a rod body, a first fixed connecting end, a second fixed connecting end, and an annular connecting groove, with a ridge 16 provided along the axial direction of the rod body and on the surface of the rod body. The annular connecting groove 17 is provided on the surface of the rod body between the first end cap and one end of the rod body.

[0064] The first fixed connection end includes: a first end cap 15, which is disposed at one end of the rod body; the second fixed connection end includes: a second end cap 18, which is disposed at the lower end of the rod body; a connection position 20 is disposed between the second end cap and the upper end of the rod body; the wall of the first through hole of the first gear is provided with a first groove (not shown in the figure) for engaging with the edge; the wall of the second through hole of the first gear is provided with a second groove (not shown in the figure) for engaging with the edge.

[0065] The use of ridges and grooves makes the force between the rod and the first or second gear more stable, avoiding the problem of asynchronous rotation caused by slippage at the connection between the rod and the first or second gear.

[0066] Another embodiment of this application is described in the following document. Figure 6 and Figure 11 As shown, the connecting mechanism further includes: a first connecting piece 1 and a second connecting piece 2; the first connecting piece 1 is used to connect with the first connecting member 3; the second connecting piece 2 is used to connect with the second connecting member 4;

[0067] The first connecting piece 1 and the second connecting piece 2 are connecting pieces; the connecting piece includes: a first piece 10, a second piece 11 and a third piece 12; the second piece 11 is provided with a first fixing hole 13 corresponding to the first through hole, and the second piece 11 is vertically disposed on the right side of the lower end of the first piece;

[0068] The third piece 12 is provided with a second fixing hole 14 corresponding to the second through hole. The third piece 12 is vertically disposed on the left side of the lower end of the first piece and is disposed opposite to the second piece 11.

[0069] See Figure 7 As shown, the second piece is sleeved on the connection position 20 through the first fixing hole 13, and the second piece is fixed to the connection position 20 between the first end cap 15 and the housing 5; the third piece 12 is sleeved in the annular connecting groove 17 through the second fixing hole 14, and the third piece 12 is fixed to the housing 5 through the second end cap 18.

[0070] The second piece is fixed to the connecting position 20 by the first end cap 15 and the front side of the housing 5, and the third piece is fixed in the annular connecting groove 17 by the second end cap 18 and the rear side of the housing, which makes the connection between the connecting piece and the connecting component more stable.

[0071] See Figures 8-10 As shown, in this embodiment, the connecting mechanism can make the included angle between the first connecting piece and the second connecting piece at least 180°, 135° or 0°, so that the included angle between the two connecting pieces of the connecting mechanism can also stay at any position between 0° and 180°, thus allowing the two connecting pieces of the connecting mechanism to be flexibly in multiple angular positions.

[0072] Optionally, the first piece is provided with multiple connection holes 19 of different sizes. Providing multiple connection holes 19 of different sizes allows the connecting piece to adapt to the specifications of connection components of various different bodies.

[0073] Optionally, the diameter of the first end cap 15 is larger than the diameter of the second end cap 18. The use of circular structures with different diameters for the first and second end caps helps to more securely fix the second and third pieces of the connecting piece between the shell and the corresponding end cap.
