Specifically, after the position of the fastener 400 on the frame 310 is adjusted according to the position of the PCIE card 20 of the motherboard, the second hand screw 410 may be rotated, and the second nut 420 moves along the axial direction of the second hand screw 410 under the action of the second hand screw 410, so as to lock the PCIE card 20 and the frame 310 by using the fastener 400. In this way, the PCIE card 20 can be kept stable in position during the test.

In one embodiment, the second nut 420 is a polygonal nut, and the polygonal nut can match with the shape of the second sliding slot 311, that is, the edge of the polygonal nut can abut against the edge of the second sliding slot 311, so that the second nut 420 cannot rotate in the second sliding slot 311. Thus, during rotation of second hand screw 410, second nut 420 does not follow second hand screw 410, but only moves in the direction of the axis of second hand screw 410. Therefore, the position of the second nut 420 can be adjusted more effectively through the second thumb screw 410, so as to achieve the locking or releasing of the fastener 400 between the PCIE card 20 and the frame body 310.

In one embodiment, the number of the mounting brackets 300 is at least two, and at least two fastening members 400 are provided on each mounting bracket 300. It is understood that the mount 300 can be fixed with a plurality of PCIE cards 20 located in the same row by using the fastener 400 on the mount 300.
