Mobile phone inner screen clamping device based on gas suction effect

The invention relates to the technical field of telephone product accessories, and discloses a mobile phone inner screen clamping device based on a gas suction effect. The mobile phone inner screen clamping device comprises a screw rod, and the left and right ends of the screw rod are both connected with moving blocks in an engaged mode, the lower ends of the moving blocks are movably provided with moving rods, and the opposite surfaces of the moving rods are slidably connected with guide rods. And a fixing plate is fixedly mounted at the lower end of the screw rod. According to the mobile phone inner screen clamping device based on the gas suction effect, firstly, the moving rods drive a fixed frame and a suction rod to get close to an inner screen downwards, and then when the suction rodmakes contact with the inner screen, the moving rods slide downwards on the fixed frame and are matched with a sliding plate to extrude a cushion pad, and the sliding plate moves downwards in the cushion pad. Therefore, the
