Strength detection device for mobile phone screen

The invention relates to the technical field of mobile phone screen strength detection, and particularly discloses a strength detection device for a mobile phone screen, which comprises a support frame, a first driving motor, a first one-way screw rod, a first sliding block, a hydraulic cylinder, a collision detection head, a pressing mechanism, a sweeping assembly and a swinging management piece. According to the mobile phone screen detection device, a first driving motor is arranged to be matched with a first one-way lead screw and other parts, the output end of a hydraulic cylinder drives a detection collision head to move downwards to collide a mobile phone screen, and when different positions of the mobile phone screen need to be detected, the first driving motor is started in a clearance mode; a first driving motor intermittently drives a first one-way screw rod to rotate, so that a first sliding block is driven to drive a detection collision head to intermittently move, the detection collision head can
