[0024] Specifically, a return spring 33 is fixedly connected between the limit block 36 and the processing machine 1 , and the return spring 33 is wound around the control end of the limit block 36 .
[0025] In this embodiment, the return spring 33 can cooperate with the limit block 36 and the processing machine 1 to achieve the purpose of pulling the limit block 36.
[0026] In this embodiment: an air guide device 4 is provided on the surface of the heat sink 5, and the air guide device 4 includes an air guide sleeve 44, which is fixedly connected to the surface of the heat sink 5, and the heat dissipation holes opened on the surface of the heat sink 5 are aligned with the air guide sleeve 44. The air guide sleeve 44 can cooperate with the heat sink 5 to achieve the purpose of guiding air exchange and blocking a small amount of dust.
[0027] Specifically, two sliders 45 are slidably connected to the surface of the air guide sleeve 44 , and the two sliders 45 are respectively located at two ends of the air guide sleeve 44 .
[0028] In this embodiment, the slider 45 can cooperate with the air guide sleeve 44 to achieve the purpose of guiding the slider 45 to slide.

[0032] Working principle: by setting up the disassembly device 3, when the sample centrifuge is in use, it is convenient for the worker to disassemble the heat sink 5 and use the equipment. The equipment achieves the purpose of separating the sample by rotating the sample at high speed. The worker pushes the control end of the limit block 36. The limit block 36 is guided by the processing machine 1 and slides. The limit block 36 slides and disengages from the bayonet 31 on the surface of the plug block 32. The limit block 36 loses its restraint on the plug block 32. The worker removes the closing cover 2 to complete the disassembly. By setting up the disassembly device 3, it is effectively convenient for the worker to disassemble the heat sink 5.

In addition, by setting up the air guide device 4, when the sample centrifuge is in use, the air exchange is guided and the heat sink 5 is closed when the sample centrifuge is idle. The device achieves the purpose of separating the samples by rotating the samples at high speed. Hot air and cold air enter the air guide sleeve 44 and are exchanged through the heat dissipation holes of the heat sink 5. When the sample centrifuge is idle, the worker pushes the blocking plate 43, and the blocking plate 43 pushes the slider 45 and the hook block 42. When the slider 45 slides to the specified position, the blocking plate 43 blocks the air guide port of the air guide sleeve 44, and the hook block 42 is squeezed with the surface of the pull block 41, and the hook block 42 is temporarily bent. When the hook block 42 slides to the top of the pull block 41, the hook block 42 returns to its original state, and the hook block 42 restricts the sliding of the blocking plate 43. By setting the air guide device 4, the air exchange is effectively guided and the heat sink 5 is closed when the sample centrifuge is idle. When the sample centrifuge is in use, dust is prevented from directly entering from the heat dissipation holes of the heat sink 5, thereby improving the practicability of the sample centrifuge, improving the auxiliary performance of the sample centrifuge, improving the air conduction performance of the sample centrifuge, and improving the dust resistance of the sample centrifuge.
