[0002] With the popularity of electronic devices such as mobile phones, tablets, and laptops, people's daily lives are becoming increasingly enriched. Electronic device stands are commonly used to meet people's needs for different heights and angles of use. The structure of an electronic device stand generally includes a base plate and a support plate for placing the electronic device. A support component is provided between the base plate and the support plate. The head of the support component is hinged to the support plate, and the tail of the support component is hinged to the base plate.

[0003] The hinge position of the existing electronic equipment bracket adopts a hinged structure in which a screw is connected to a rotating connecting rod. After the hinge structure expands and contracts due to heat, the shape of the connecting rod changes, and the connection position of the metal screw is offset, resulting in the failure of the supporting force of the connecting rod. Summary of the Invention

[0004] The utility model aims to provide an electronic equipment bracket, which can improve high temperature resistance and solve the problem of failure of the supporting force of the hinge structure due to thermal expansion.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an electronic device bracket, and the specific implementation scheme is as follows:
