Specifically, when the power supply body 3 needs to be installed, the fixed foot 4 at the bottom of the power supply body 3 is inserted into the slot on the surface of the mounting seat 2, and then the knob 9 is rotated. The knob 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the active bevel gear 8 to rotate. The active bevel gear 8 drives the driven bevel gear 6 to rotate, so that the forward and reverse screw rods 5 rotate. When the forward and reverse screw rods 5 rotate, the threaded block 10 is driven to move, so that the two threaded blocks 10 move away from each other until the L-shaped block 11 is inserted into the rectangular hole on the surface of the fixed foot 4, thereby limiting the threaded block 10, and then limiting the power supply body 3. When disassembly is required, the knob 9 is rotated in the opposite direction to disengage the L-shaped block 11 from the inside of the rectangular hole. Therefore, the computer power supply can be installed and disassembled without the aid of specific tools, which is convenient for disassembly and assembly.

[0023] In this embodiment, the left outer surface of the main housing 1 is movably hinged with a box door 12, the left outer surface of the box door 12 is fixedly connected with a rotating seat 13 near the front end, the outer surface of the rotating seat 13 is rotatably connected to a limiting rod 15, the left outer surface of the main housing 1 is located at the front end of the box door 12 and is fixedly connected with a C-shaped seat 14, the top outer surface of the C-shaped seat 14 is movably inserted with a movable rod 16, the bottom outer surface of the movable rod 16 is fixedly connected to a limiting block 17, the top inner surface of the C-shaped seat 14 is fixedly connected with a spring 18, and the bottom outer surface of the spring 18 It is fixedly connected to the top outer surface of the limit block 17, and a limit groove matched with the limit block 17 is formed on the top outer surface of the limit rod 15. Specifically, when the power supply body 3 needs to be disassembled, the host casing 1 needs to be disassembled. At this time, the movable rod 16 is lifted upward to compress the spring 18 until the limit block 17 is disengaged from the inside of the limit groove, and the limit rod 15 is pulled so that the limit rod 15 drives the box door 12 to open, so that one side of the host casing 1 can be disassembled without the aid of external tools, thereby further improving the disassembly and assembly efficiency of the computer power supply.

[0024] In this embodiment, a heat dissipation port 19 is provided on the outer surface of the box door 12, and a dustproof net 20 is provided at the periphery of the heat dissipation port 19.

[0030] When the power supply body 3 needs to be disassembled, the host casing 1 needs to be disassembled. At this time, the movable rod 16 is lifted upward to compress the spring 18 until the limit block 17 is disengaged from the inside of the limit groove, and the limit rod 15 is pulled so that the limit rod 15 drives the box door 12 to open, so that one side of the host casing 1 can be disassembled without the aid of external tools, which further improves the efficiency of disassembly and assembly of the computer power supply. When closing, close the box door 12 and rotate a section of the limit rod 15 to the inside of the C-shaped seat 14. When the limit rod 15 contacts the limit block 17, the limit block 17 is squeezed to compress the spring 18 until the limit block 17 is inserted into the limit groove, and the limit rod 15 is limited, thereby closing the box door 12.
