[0031] When the utility model is in use, when the components inside the computer body 1 are damaged, the hexagonal wrench can be inserted into the groove 503 at the end of the screw rod 502, and then the screw rod 502 is rotated by the hexagonal wrench, and the screw rod 502 threads drive the two sliders 504 to move, and the sliders 504 drive the abutment plates 505 to move away from the inclined groove 506. When the ends of the abutment plates 505 are disengaged from the inclined groove 506, the rotation of the screw rod 502 can be stopped, and then another screw rod 502 can be rotated to make the ends of the other two abutment plates 505 also disengage from the inside of the inclined groove 506. When the ends of the four abutment plates 505 are all disengaged from the inside of the inclined groove 506, the front end cover 2 can be held by hand, and then the front end cover 2 can be removed from the computer body 1, and the quick removal of the front end cover 2 is completed.

Next, the above operation can be repeated to make the other plug rod 903 not engaged with the slot 904, and then the computer body 1 can be rotated. The rotation of the computer body 1 will drive the display screen 11 and the connecting plate 6 to rotate together. When the inclination angle of the display screen 11 is adjusted, the end of the rod 903 will face the other slot 904. At this time, the stop block 906 can be pushed. When the stop block 906 loses its support for the slide bar 901, the return spring 902 will shrink and drive the slide bar 901 to move. The movement of the slide bar 901 will drive the rod 903 to move toward the other slot 904 and engage with the other slot 904. When one rod 903 is engaged with the slot 904, the other rod 903 is also engaged with the slot 904. When both rods 903 are engaged with the slots 904, the computer body 1 cannot rotate. At this time, the adjustment of the inclination angle of the display screen 11 is achieved.The angle of the display screen 11 can then be adjusted according to the habits of different users, thereby effectively improving the flexibility of operation.
