Two threaded holes are provided at positions on the support plate 32 corresponding to the positions of the two slide grooves 311. Fastening bolts 36 pass through the slide grooves 311 and are then inserted into the threaded holes for fastening. As the slide grooves are strip-shaped, the press blocks 31 may move forward and back on the support plate 32 by using the fastening bolts 36 as guides when the fastening bolts 36 are not fastened.
During installation of the expansion card 34, the fastening bolts 36 are loosened at first, and the press blocks 31 are placed at an end away farthest from the installation direction of the expansion card 34. Subsequently, the expansion card 34 is mounted inside a card base, then the press blocks 31 are moved so as to allow the press blocks to press the expansion card 34, and finally the fastening bolts 36 are fastened. Thus, the expansion card 34 is secured by the press blocks 31, and will not get loose or even fall off due to the vibration of the computer, thereby ensuring the working state of the computer.
The expansion card press mechanism further includes cushion blocks 33 which are mounted on the press block 31. The press blocks press the expansion card 34 through the cushion blocks 33. The cushion blocks 33 are rubber cushion blocks with a function of buffering, so that the expansion card 34 will be not crushed due to the violent vibration of the computer. Furthermore, a plurality of grooves 331 for limiting is provided on the expansion card 34. The grooves 331 are buckled on the expansion card 34 for avoiding jitter. The grooves 331 are a plurality of grooves capable of pressing expansion cards 34 of different height.
