In this way, the friction with the screw rod 31 can be increased, thereby improving the braking effect.
When the circuit board is placed in the placement frame 2, the circuit board contacts the anti-slip pad 10, and the anti-slip pad 10 increases friction with the circuit board. In this way, the sliding phenomenon of the circuit board on the buffer plate 61 can be prevented from affecting the passing of the detection rod 33, thereby improving the accuracy of the hole of the detection rod 33 passing through the circuit board.
Finally, it is necessary to state that: the foregoing is provided to assist in understanding the technical solutions of the present invention, and is not to be construed as limiting the scope of protection of the present invention; insubstantial modifications and variations from the above teachings are within the scope of the invention as claimed.
