[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the mainboard is installed, the worm gear is driven to rotate by rotating the worm, thereby driving the rotating disk to rotate. When the rotating disk rotates, the connecting rod and the card block can be pushed away from or close to each other by the transmission rod, and finally the card block is inserted into the card slot or detached from the card slot to fix the mainboard. In this way, the chassis and the mainboard are no longer fixedly connected by screws, but are fixedly connected by card blocks. The fixing process is convenient and fast, and the operation is convenient.

[0014] 2.
