When it is compressed to the bottom, Figure 3 As shown, after the direct display circuit board 2 is placed into the clamping tool body 1, the bottom shell 3 is placed into the clamping tool body 1, and then the pedal is pressed to control the cylinder to move the metal column to the left. Under the action of the spring 502, the elastic clamp 501 also moves with the movement of the metal column f, clamping the bottom shell 2 so that the bottom shell 2 is aligned with the direct display circuit board 3, thereby achieving the purpose of clamping the circuit board and the bottom shell.
