Description

RELATED APPLICATIONS The present patent document claims the benefit of priorities to Chinese Patent Application No. 202422683396.6, filed on Nov. 4, 2024, and Chinese Patent Application No. 202422885463.2, filed on Nov. 25, 2024, and entitled “ROTATING BRACKET FOR PROTECTIVE CASE,” the entire contents of each of which are incorporated herein by reference. BACKGROUND 1. Technical Field The present disclosure relates to the field of electronic device accessories, and specifically, to a rotating bracket for a protective case. 2. Background Information In the current mobile device market, protective cases with rotating brackets are highly favored by consumers for their convenience and practicality. These products can not only provide necessary protection for mobile phones, but also support various usage scenarios, such as serving as a stand for video watching or offering stable support during photographing. However, existing designs of the protective cases with rotating brackets often share a common issue that the rotating brackets are too complex in structure. This not only increases product production cost, but also makes installation and usage less intuitive, leading to a poor user experience. BRIEF SUMMARY An objective of the present disclosure is to provide a rotating bracket with a high degree of freedom in supporting angle adjustment and a simple structure, aiming at the foregoing defects of an existing bracket used on a protective case. An objective of the present disclosure can be achieved through the following technical solutions. The present disclosure provides a rotating bracket for a protective case, including a rotating assembly arranged on a back surface of the protective case and a supporting plate, where the rotating assembly includes a rotating body, a rotating base, and an elastic sheet; the rotating body is arranged on the back surface of the protective case and is provided with a rotating hole; the rotating base is connected to the supporting plate through a rotating hinge, and a clamping groove is formed along a periphery of the rotating base; the rotating base is placed in the rotating hole, and the elastic sheet is snap-fitted in the clamping groove and is snap-fitted with the rotating hole; and the rotating base rotates in the rotating hole under force, driving the supporting plate to rotate. Preferably, the elastic sheet is C-shaped and the clamping groove is correspondingly C-shaped; and a sector angle formed by connecting a center of the C-shaped elastic sheet as a circle center to two ends of an opening of the elastic sheet is 90°. Preferably, a middle portion of the C-shaped clamping groove is recessed to form a recessed hole, and a protrusion fitted with the recessed hole is formed in a corresponding position on the elastic sheet. Preferably, a toothed groove is formed in an inner circumferential surface of the rotating hole; the rotating base is provided with a sliding groove and a shaft groove, and the sliding groove is perpendicular to the shaft groove; and the shaft groove extends through the rotating base and is configured to accommodate a rotating shaft connected to the rotating hinge; and a spring and a positioning ball are arranged in the sliding groove, and the positioning ball rolls along the toothed groove under a squeezing and elastic action of the spring to enable the rotation of the rotating base.
