[0002] At present, mobile phone gravity holders are widely used. The structure of mobile phone gravity holders is relatively simple. The left and right clamping parts and the lower clamping part are linked to each other through transmission mechanisms such as gears. When a mobile phone is placed, the mobile phone's own gravity is used to press down the lower clamping part, and then the left and right clamping parts are synchronously linked to shrink inwards to clamp the mobile phone, which is relatively convenient to operate.
