Provided is a mobile-phone gravity bracket, comprising a base, a pull rod used for receiving a mobile phone, and a left clamp arm and right clamp arm used for holding the mobile phone; a positioning shaft is arranged on the base, the left clamp arm and right clamp arm are rotatably mounted on the positioning shaft, and the pull rod is respectively drivingly connected to the left clamp arm and right clamp arm. During use, the mobile phone is placed directly on the pull rod; under the effect of gravity on the mobile phone, the pull rod drives the left clamp arm and right clamp arm to rotate in opposite directions so as to clamp the handset; using the gravitational force on the mobile phone and simple mechanical principles, automatic clamping of the mobile phone is achieved; the structure is simple, and production costs are significantly reduced.
