[0034] Working principle and process:

[0035] Before using the centrifuge body 1, place the centrifuge body 1 on the supporting circular plate 33 at the output end of the electric lifter 32 of the tightening assembly 3, install the positioning frame 31 on the other side to the outside of the horizontal axis 5 through the slide plate 8 at the bottom, push the positioning frame 31 to move and fit to the position of the centrifuge body 1, install the spring 7 to be sleeved on the outside of the horizontal axis 5, tighten the positioning cap 6, clamp the positioning frame 31 to the outer shell surface of the centrifuge body 1 through the elastic potential energy of the spring 7, perform preliminary positioning, rotate the adjusting threaded shaft 36 in the tightening assembly 3, control the outer pressing block 37 to descend along the vertical groove of the positioning frame 31 to the centrifuge body 1, clamp the centrifuge body 1, open the electric lifter 32, lift the supporting circular plate 33 at the top, pull out the stretching rod 35 inside the guide frame 34, and after the stretching rod 35 is unfolded, a larger supporting structure is formed at the bottom of the centrifuge body 1, and the upper limit of the pressing block 37 is cooperated to complete the operation of clamping the centrifuge body 1.
