[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. By providing multiple positioning members and opening multiple threaded holes at equal intervals on the upper side of the fixed support seat, the computer motherboard is placed on the fixed support seat, and the multiple positioning members are sequentially positioned at the four side edges of the computer motherboard. The first rotating head on the positioning member is rotated to insert the movable rod into the threaded hole at the edge of the computer motherboard. The connecting column blocks the edge of the computer motherboard laterally. Then, the second rotating head is rotated to move the extrusion block downward to squeeze the edge of the computer motherboard, which greatly improves the fixing effect of the computer motherboard, making the computer motherboard firmly fixed on the fixed support seat and simple to operate.

[0017] 2. The threaded connection between the positioning piece and the threaded hole on the fixed bearing seat makes the installation between the positioning piece and the fixed bearing seat simple and easy to disassemble and separate, thereby facilitating the adjustment of the installation position of each positioning piece on the fixed bearing seat, thereby being able to fix computer motherboards of different sizes.
