[0028] The specific settings and functions of the limiting structure 4 and the protective structure 5 are described in detail below.
[0029] Reference Figure 2 and Figure 3 As shown, in this embodiment: the limiting structure 4 includes two rectangular frames 401, the two rectangular frames 401 are fixedly connected to the two sides of the centrifuge body 2 respectively, the surfaces of the two rectangular frames 401 are slidably inserted with latches 402, the inner walls of the two rectangular frames 401 are slidably inserted with rectangular rods 43, the surfaces of the rectangular rods 43 are provided with a plurality of circular grooves 404, one end of the two rectangular rods 43 is fixedly connected with a frame 405, one side of the frame 405 is rotatably connected with a threaded rod 406, and the surface of the threaded rod 406 is threadedly connected with a pressing plate 407. The surface of the pressing plate 407 is slidably penetrated by two round rods 408, and the two round rods 408 are fixedly connected to the surface of the frame 405. The pressing plate 407 will slide along the surface of the round rods 408 during the movement, and the round rods 408 reach the effect of limiting the moving path of the pressing plate 407, thereby preventing the pressing plate 407 from rotating during the movement. The end of the threaded rod 406 away from the bottom plate is fixedly connected to a rotating disk 409, and the cross section of the rotating disk 409 is in the shape of a cross. The rotation of the rotating disk 409 will drive the threaded rod 406 to rotate, and the rotation of the rotating disk 409 will drive the threaded rod 406 to work. The arc surface of the latch 402 is covered with a spring 410, and the two ends of the spring 410 are respectively fixedly connected to the latch 402 and the frame 405.

When the centrifuge body 2 moves to a suitable position, the rectangular rod 43 slides into the rectangular frame 401. When the centrifuge body 2 moves to a suitable position, the latch 402 is released. The latch 402 is inserted into the circular groove 404 with the help of the contraction force of the spring 410. The latch 402 reaches the position of the rectangular frame 401, thereby limiting the position of the centrifuge body 2.
[0032] When it is necessary to protect the heat dissipation net 3, first rotate the threaded rod 406. The threaded rod 406 will rotate on the surface of the centrifuge body 2. The threaded rod 406 will drive the extension plate 52 to move with the help of the thread. The extension plate 52 will drive the L-shaped plate 53 to move. The L-shaped plate 53 will move toward the direction close to the centrifuge body 2. The movement of the L-shaped plate 53 will drive the protective block 54 to move. When the L-shaped plate 53 moves to a suitable position, the L-shaped plate 53 will cover the heat dissipation net 3, so as to cover the heat dissipation net 3 when the centrifuge body 2 is not in use, so as to prevent dust from adhering to the surface of the heat dissipation net 3. When the L-shaped plate 53 is attached to the surface of the heat dissipation net 3, the protective block 54 on the surface of the L-shaped plate 53 will slide into the hole of the heat dissipation net 3.
