Abstract
A parallelogram linkage automatic clamping holder includes a rear base, a bottom support arm, a left clamping arm, a right clamping arm, and a return elastic member. When in use, the bottom support arm is moved downward by the weight of a mobile phone. By the deformation principle of the parallelogram, clamping parts move inward obliquely upward to clamp the mobile phone automatically. The clamping surfaces of the clamping parts don't have an angle change to ensure that the mobile phone has a larger contact surface with the clamping surfaces, providing a better clamping effect.
