[0023] Working principle: The upper clamping plate 1 and the lower clamping plate 3 are designed as an integrated whole. The first shaft 6 passes through the first shaft hole 7 on the shaft bracket 5 and the second shaft hole 8 on the upper clamping plate 3 so that the upper clamping plate 3 can rotate with the first shaft 6 as the axis. When working, open the upper clamping plate 3, position the circuit board through the second positioning column 9, cover the upper clamping plate 3, press down the upper clamping plate 3 so that the lock buckle 12 is pressed down along the arc surface above the lock head 17 to push the lock head 17 to rotate counterclockwise. After the lock buckle 12 is in place, the coil spring 16 drives the lock head 17 to rotate clockwise to buckle the lock buckle 12 so that the upper clamping plate 3 will not automatically rotate during work. The first positioning column 11 enters the first positioning hole 10 to ensure that the position of the upper clamping plate 3 will not shift. The first rubber pad 2 and the second rubber pad 4 ensure that the two clamping plates will not cause damage to the circuit board while fixing the circuit board. At this time, the circuit board can be operated through the operation window 13. When the circuit board needs to be removed, the lock 17 is turned counterclockwise. The lock shaft 15 on the lock 17 will rotate in the lock shaft hole 14 and then release the lock buckle 12 to open the upper clamping plate 3 and take out the circuit board. After letting go, the coil spring 16 drives the lock 17 to rotate clockwise to reset it.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
