The lifting mechanism 200 pushes the grinding mechanism 300 to move up and down, so that the grinding end of the grinding mechanism 300 is inserted into or removed from the No. 1 test tube 500, so as to grind the substance in the No. 1 test tube 500 and then extract it, and then put it into the separation and mixing mechanism 400 for centrifugation or mixing operation; the separation and mixing mechanism 400 is used for centrifugation or mixing. The separation and mixing mechanism 400 in this embodiment can be a mechanism with centrifugation and mixing functions in the prior art, or a newly designed structure with centrifugation and mixing functions in one.

[0054] Specifically, the mounting seat 600 is a hollow tube column structure for fixing the No. 1 test tube 500. Preferably, in order to enhance the stability of the No. 1 test tube 500, the mounting seat 600 can be composed of two hollow tube column structures connected at the front to form a mounting seat 600 with a certain height.

[0055] In order to make the structure of the present invention beautiful, compact and effective, and easy to operate, the shell 100 also includes a left side plate 101, a right side plate 102, a front side plate 103, a rear side plate 104, and a top plate 105, which are enclosed together with the bottom plate 106 to form a hexahedron; wherein the lifting mechanism 200 is located on a side close to the rear side plate 104, the separation and mixing mechanism 400 is located on a side close to the front side plate 103, the mounting seat 600 is located between the lifting mechanism 200 and the separation and mixing structure, and the lower part of the grinding mechanism 300 corresponds to the top surface of the mounting seat 600;

When the rotating handle 204 is rotated, the rotating gear 203 and the lifting plate 205 are driven to move in opposite phases, so that the grinding mechanism 300 moves up and down. When the grinding mechanism 300 moves downward and its bottom end is located in the first test tube 500, a crushing operation can be performed. After the crushing operation is completed, the rotating handle 204 can be rotated in the opposite direction to make the lifting plate 205 move upward, thereby driving the grinding mechanism 300 to move upward to leave the first test tube 500.

[0065] Among them, an adjustment hole 218 is correspondingly provided on the No. 1 plate 214 and the No. 2 plate 215, which is used for adjusting the bolt 219 to pass through the two adjustment holes 218 at the same time to adjust the size of the arc clamping ring 216, and it is also convenient to adjust the tightness of the grinding mechanism 300 fixed to the lifting mechanism 200; the No. 1 plate 214, the No. 2 plate 215, and the arc clamping ring 216 are formed in one piece.

[0066] In order to enhance the stability of the lifting mechanism 200 , the bottom end of the fixing column 201 is connected to the bottom of the housing 100 via a pad.

[0067] In a specific embodiment, according to Figure 4 , Figure 8-Figure 10 As shown, the grinding mechanism 300 includes a speed regulating motor 301, a support sleeve 302, and a cutter head system 303. The speed regulating motor 301 is located on the upper part of the arc-shaped clamp ring 216; the output shaft of the speed regulating motor 301 is connected to the cutter head system 303 through a coupling, and the support sleeve 302 is sleeved outside the coupling and fixed by the arc-shaped clamp ring 216, which can avoid damage to the grinding mechanism 300 and reduce costs. When the support sleeve 302 is damaged, it only needs to be replaced without replacing the entire grinding mechanism 300;

[0068] The inner diameter of the arc-shaped collar 216 matches the outer diameter of the support sleeve 302 and is used to fix the grinding mechanism 300 to the lifting mechanism 200;

[0070] In a specific implementation, a coaxial through hole 310 is provided in the grinding column 308 along its axis, at least two connected liquid flow grooves 311 with arc-shaped cross sections are provided on the circumference of the grinding column 308, and a plurality of overflow grooves 312 are evenly provided on the circumference of the tool bar grinding sleeve 307, so that the ground material in the No. 1 test tube 500 is sheared by the blade 309 and sucked from the through hole 310, then flows through the liquid flow groove 311, and finally flows from the overflow groove 312 to the No. 1 test tube 500 after being squeezed by the inner wall of the tool bar grinding sleeve 307;

[0071] The through hole 310 corresponds to the hole opened on the blade 309. Specifically, the crushing is performed as follows: the speed regulating motor 301 is turned on, and the cutter head system 303 rotates at a high speed. At this time, a cutting force and an upward and downward dispersion force are generated in the No. 1 test tube 500, and the continuously crushed material moves from the hole of the blade 309 to the hole in the center of the grinding column 308, and then flows out of the liquid flow groove 311 and is squeezed and ground in the corresponding cavity formed between the inner wall of the tool bar grinding sleeve 307. This structure has a good grinding effect, and different blades 309 can also be replaced according to different grinding objects; more specifically, a plurality of grooves connected to the overflow groove 311 are opened on the top surface of the tool bar grinding sleeve 307, and the grooves are opened along the circumferential direction of the top surface, so that the material moving to the top surface of the tool bar grinding sleeve 307 under the action of power flows to the overflow groove 311 to avoid blockage.
