By disassembling the rocker arm 13 and crank 12, and changing the installation position of the rocker arm 13 on the crank 12, the amplitude of the reciprocating motion of the rocker arm 13 can be adjusted, thereby adjusting the force of the tapping test. By activating the first motor 6 and the second motor 8, the first lead screw 61 and the second lead screw 81 can be rotated, causing the moving frame 7 to slide on the guide post 10 and the slider 9 to slide on the moving frame 7. This allows for movement of the pressing block 17, thereby changing the test point on the mobile phone display screen 2. This enables a comprehensive and accurate test of the mobile phone display screen 2, allowing for adjustment and control of the tapping force during the tapping test, improving the accuracy of the test results. The display screen 2 facilitates observation of the test results and control of the test process.
