When the position of the annular groove 10 is aligned with the position of the rotating locking plate 8, the locking plate 8 is reversely rotated under the action of the torsion spring 9 to enter the interior of the annular groove 10 and contact the inner wall of the annular groove 10, thereby completing the installation of the main board 1. Through the above structure, when installing, it is only necessary to be consistent with the normal installation procedure, and the screw 5 can be automatically locked after the screw 5 is screwed in without installing the remaining components, thereby avoiding the problems of slipping and loosening of the screw 5 caused by vibration, and saving the time consumed by the need to install the auxiliary frame separately.

When the main board 1 needs to be disassembled and unlocked, it is only necessary to press the button 12. The button 12 moves after being subjected to force and synchronously compresses the spring 14. After the button 12 moves, it synchronously drives the unlocking column 13 to move. After the unlocking column 13 moves, it contacts the displacement plate 11 and forces the displacement plate 11 to move.
