Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic application processing and manufacturing technology, and more specifically relates to a multi-angle adjustable bracket device. Background Technology
[0002] The rapid development of electronic devices has also led to the emergence of numerous electronic accessory products based on customer experience. These include protective cases to safeguard the appearance of electronic products, and stands to adjust the viewing angle. Take phone stands as an example: they offer a variety of applications. For instance, when participating in video conferences or online courses, a phone stand ensures the phone remains in a stable position. If you need to view meeting materials or take notes while communicating with others, a stand allows you to point your phone's camera at yourself while maintaining a comfortable viewing angle for others or course content. In remote work scenarios, you can place your phone stand on your desk to keep yourself centered in the frame and clearly see shared documents and explanations from colleagues. Utility Model Content

Normally, the spring (4) does not work when the toothed limiter (3) and the mounting base (1) are placed horizontally. When the toothed limiter (3) is lifted, the spring (4) exerts downward pressure on the toothed limiter (3). When the toothed limiter (3) is perpendicular to the mounting base (1), the downward pressure of the spring (4) is the greatest.
[0006] Preferably, the toothed limiter (3) is formed by combining multiple toothed grooves (32) and multiple protrusions (31), with a toothed groove (32) formed between two protrusions (31). The mounting base (1) is provided with multiple limiter grooves (11), and the structure and number of the limiter grooves (11) on the mounting base (1) are matched one-to-one with the protrusions (31) of the toothed limiter (3).

The locking head structure (23) has a rotation effect within the kit structure (13). The support arm (2) is configured as a concave structure. When it rotates 90 degrees, the support arm (2) is perpendicular to the mounting base (1). The upper frame (24) of the support arm (2) is engaged in the middle toothed groove (32) of the toothed limiter (3). After the structure is fixed, it has a certain space for handheld use.
[0008] Preferably, after the mounting base (1) and the support arm (2) are installed, two guide grooves (14) are also provided on the mounting base (1) to allow the support arm (2) to rotate in a horizontal or vertical manner after installation. The support arm has an adjustment function between 0 and 180 degrees, and the specific angle is determined by the position of the toothed limiter. During normal operation, when the support arm (2) is placed horizontally at 0 and 180 degrees, the support arm (2) and the mounting base (1) are at 0 or 180 degrees horizontally.
[0009] Preferably, the multi-angle adjustable bracket device is installed on the mobile phone or tablet device, so that the customer can conveniently adjust the application angle of the device during use.
