However, the present invention is not limited to this, and the rotary element 2 may be rotatably attached to the bracket 1 in another configuration, for example, the shaft 4 is not provided, the first through hole 21 penetrating the rotary element 2 is provided at one end of the rotary element 2, the housing groove 11 is provided in the bracket 1, one end of the rotary element 2 having the first through hole 21 is provided in the housing groove 11, two opposite protrusions are provided in the housing groove 11, and the rotary element 2 is rotatably attached to the bracket 1 by inserting the two protrusions into the first through hole 21 from both ends of the first through hole 21. However, in contrast, according to the structure of the embodiment, the shaft rod 4 is disposed and installed in the first through hole 21, and both ends of the shaft rod 4 are rotatably installed on the bracket 1, compared with the connection between the bracket 1 and the rotary member 2 through the two protrusions, the rotary member 2 can rotate around the shaft rod 4 relative to the bracket 1, and the rotation process can be ensured to be stable and not easy to fail due to the shaft rod 4 serving as a rotation standard member.

In addition, in the above-described embodiment, the elastic assembly 3 includes the elastic member 31, the moving member 32, and the pressing member 33. The moving member 32 and the extrusion member 33 are both slidably sleeved on the shaft rod 4, the extrusion member 33 is fixed on the bracket 1, the moving member 32 is installed in the first through hole 21 in a manner of synchronously rotating with the rotating member 2, the elastic member 31 is installed in the first through hole 21, and one end of the elastic member 31 is in contact with the moving member 32. The moving member 32 abuts against the extrusion member 33 and the mutually facing opposite faces of the moving member 32 and the extrusion member 33 are cam faces mutually matched, and the cam faces are configured to enable the moving member 32 to gradually get away from the extrusion member 33 under the working condition that the rotating member 2 rotates, so that the elastic member 31 is compressed, and the elastic member 31 rebounds to gradually get close to the extrusion member 33 after the distance between the cam faces and the extrusion member 33 reaches the maximum.

However, the elastic member 3 may be formed in other structures, for example, the pressing member 33 is not provided, but the shaft 4 is directly provided as a stepped shaft, and one stepped surface of the stepped shaft is formed as a cam surface in the embodiment to be engaged with the moving member 32, or the elastic member 3 may be formed in other structures, as long as the function of automatically opening and closing the rotating member 2 with respect to the bracket 1 after the rotating member 2 of the rotating shaft is rotated to a certain position with respect to the bracket 1 by the elastic member 3 in the specific embodiment can be realized.

In contrast, it is preferable that the first through hole 21 is a stepped hole for stably contracting the spring according to the structure of the embodiment, so as to ensure that the spring is stably contracted and contracted, i.e., is always contracted and contracted along the central axis of the spring, thereby prolonging the effective service life of the spring, and reducing the number of assembling parts as much as possible to simplify the assembling process of the rotating shaft.

In addition, in the above-described embodiment, the stopper groove 12 is provided at the side portion of the bracket 1 located at the receiving groove 11, and the stopper protrusion 22 is provided at the end portion of the rotary member 2, and the stopper protrusion 22 is configured to rotate inside the stopper groove 12 to limit the maximum angle at which the rotary member 2 can rotate relative to the bracket 1.
