[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0042] Example 1

[0043] Refer to Figures 1-4 , a tissue sample shredding device, including a main body component 1, and the main body component 1 includes: a base 11, on the top of which there is a tank body 12; a cover body 13, arranged on the top of the tank body 12; a crushing mechanism 14, arranged on the cover body 13; a stabilizing component 2 is arranged on the base 11, and the stabilizing component 2 includes: connecting rods 21, symmetrically hinged to the bottom of the base 11; sliders 22, hinged to the bottom of the connecting rods 21; sliding rods 23, penetrating and connected to one side of the sliders 22, and four groups are symmetrically arranged, and the sliders 22 are slidably connected to the sliding rods 23; struts 24, arranged at the interfaces of the sliding rods 23; springs 25, fixedly connected between the struts 24 and the sliders 22, and the springs 25 are sleeved outside the sliding rods 23; a bottom plate 26, fixedly connected to the bottom of the struts 24; a fixing mechanism 27, arranged on the top of the base 11. The fixing mechanism 27 includes: a lead screw 271, rotatably connected to the top of the base 11; a threaded block 272, threadedly connected to the lead screw 271; a turning handle 273, fixedly connected to the top of the lead screw 271; a smooth shaft 274, fixedly connected to the top of the base 11; a sliding sleeve 275, slidably connected to the outside of the smooth shaft 274; a pressing plate 276, fixedly connected between the threaded block 272 and the sliding sleeve 275. A fixing ring 3 is arranged on the top of the base 11, and the inner diameter of the fixing ring 3 is equal to the outer diameter of the tank body 12.

[0044] During use, the staff places the tissue sample to be broken in the inner part of the tank body 12, covers the cover body 13, places the tank body 12 on the base 11, and uses the stabilizing component 2 to fix the tank body 12 and the cover body 13: First, use the fixing mechanism 27 to fix the cover body 13 and the tank body 12 above the base 11 to prevent the tank body 12 from tilting when the breaking mechanism 14 is started. The staff rotates the turning handle 273, the turning handle 273 drives the lead screw 271 to rotate, and the threaded block 272 threadedly connected to the lead screw 271 drives the pressing plate 276 to move downward. The sliding sleeve 275 at the other end of the pressing plate 276 slides downward on the optical axis 274 to increase the stability of the movement of the pressing plate 276. Continuously move the pressing plate 276 downward to squeeze the cover body 13 downward. After the tank body 12 is fixed to the base 11, stop rotating the turning handle 273. At this time, start the motor power supply of the breaking mechanism 14. Here, the breaking mechanism 14 adopts a conventional breaking method. For example, it can usually be composed of a crushing container and a mashing component. The mashing component is often composed of a motor connected to a mashing rod, and various cutting tools are provided on the mashing rod. As long as the tissue sample can be broken, the specific structure will not be elaborated here. The vibration generated when the breaking mechanism 14 is started is transmitted to the connecting rod 21 through the base 11. The connecting rod 21 squeezes the slider 22 downward. After being squeezed, the slider 22 slides outward on the sliding rod 23 at the same time. The slider 22 squeezes the spring 25. After the spring 25 is deformed, it absorbs the vibration transmitted from the base 11, reduces the vibration of the tank body 12, reduces the noise, and increases the stability when the tissue sample in the tank body 12 is crushed. After the tissue sample is broken, the staff rotates the turning handle 273 in the reverse direction, and the linkage pressing plate 276 moves upward. At this time, the cover body 13 and the breaking mechanism 14 are removed from above the tank body 12, and the tank body 12 is removed from the base 11 to facilitate pouring out the broken tissue sample. The fixing ring 3 on the base 11 is used to limit the placement position of the tank body 12. When the tank body 12 is placed in the fixing ring 3, the fixing ring 3 fixes the bottom end of the tank body 12 to prevent the tank body 12 from tilting and is used to increase the stability of the tank body 12.

[0045] Embodiment Two

[0046] On the basis of Embodiment One, an auxiliary function is added.

[0047] Refer to Figures 1-4 There is a telescopic shell 4 fixedly connected between the base 11 and the bottom plate 26. The middle part of the pressing plate 276 is designed to be hollow. A sealing ring 5 is fixedly connected to the bottom surface of the cover body 13, and the diameter of the sealing ring 5 is equal to the inner diameter of the cover body 13.

[0048] The telescopic shell 4 expands and contracts when the base 11 is vibrated and moves up and down. The telescopic shell 4 protects the internal parts to prevent foreign objects from entering between the base 11 and the bottom plate 26, which may affect the normal use. The hollow design of the pressing plate 276 can achieve the extrusion of the cover body 13 while avoiding affecting the normal use of the motor in the crushing mechanism 14. When the cover body 13 is sleeved on the top of the tank body 12, the sealing ring 5 inside the cover body 13 abuts against the inner side wall of the tank body 12 to prevent the tissue sample from splashing out of the tank body 12 when the crushing mechanism 14 crushes the tissue sample, which is not conducive to the normal crushing of the tissue sample and increases the cleaning pressure on the staff.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
