Similarly, the user pulls the connecting ring 19, which allows the locking rod 20 to disengage from the locking sleeve 21, thereby adjusting the position of the clamping plate 9.

[0035] The usage process of this utility model is as follows: The user turns the drive shaft 16, the drive shaft 16 rotates and drives the drive gear 17 to rotate, the drive gear 17 rotates and drives the two toothed plates 14 to move, the two toothed plates 14 move outward and drive the two moving plates 12 to move, the moving plates 12 move and drive the two moving rods 11 and the slider 10 to move, the slider 10 moves and drives the two clamping plates 9 to move, thereby clamping and positioning keyboards of different sizes. After positioning is completed, the keyboard is placed in the drawer 4 and put into the device. After positioning is completed, the user opens the program and presses the start button with both hands to start the program. The height scanning test module 7 presses down the pressure plate to press the keyboard, and at the same time the probe touches the keycap. The laser tube 8 senses the keyboard, the test camera 2 starts to take pictures, and the abnormal height keycap is specially displayed. After the test is completed, the keyboard is taken out and the abnormal keycap is marked with a marker.

[0036] The above description is merely a preferred embodiment of this utility model.
