An arc groove 16 is formed in one side, close to the placing groove 3, of the first piston 9, a ball 17 is movably connected in the arc groove 16, the ball 17 can roll in the arc groove 16, and the ball 17 cannot be separated from the corresponding arc groove 16. The balls 17 are partially located outside the arcuate slot 16. When the mobile phone shell is positioned, the first piston 9 moves to drive the ball 17 to move, so that the ball 17 moves to contact with the side wall of the mobile phone shell.
The vertical groove 6 is fixedly connected with a first electromagnetic valve 11, and in an initial state, the first electromagnetic valve 11 is in an open state.
