Embodiment Construction
[0031] Below in conjunction with specific embodiment, content of the present invention is described in further detail, figure 1 It shows a three-dimensional schematic view of the rotary clamping handheld tissue grinder of the present invention, which consists of a grinding pestle 1, a sleeve 2, an elastic part (not shown in the figure), a one-way rotary clamping mechanism 4, and a protective cover 5. Partially constituted, wherein the grinding pestle 1 consists of a grinding pestle body 11 and a large-diameter portion 12 fitted on the upper end of the grinding pestle body 11 (such as image 3 shown in ). The one-way rotation locking mechanism 4 includes a helical groove portion 41 and a vertical groove 42 communicating with the helical groove portion 41 . The helical groove portion 41 includes first helical grooves 411 , second helical grooves 412 , and rectangular grooves 413 that are arranged alternately in sequence. Along the rotation direction of the grinding pestle 1 , ...

Abstract
The invention relates to a hand-held tissue grinder with rotating limit position. The hand-held tissue grinder with rotating limit position comprises a grinding pestle, a sleeve matched with the grinding pestle, an elastic part abutting on the upper end of the grinding pestle, and a unidirectional rotating clamping mechanism for positioning the grinding pestle; the grinding pestle is composed of agrinding pestle body and a large diameter part sleeved on the upper end part of the grinding pestle body. This way, as the one-way rotate clamping mechanism is utilized, the grinding pestle is reliably positioned under the action of the elastic part, and after the grinding is finished, the grinding pestle is pressed again, and the grinding pestle is separated from the unidirectional rotating clamping mechanism by rotating the grinding pestle, so that the grinding pestle automatically ejects under the resilient force of the elastic part, so that the operation process is more quick and efficient, and the infection of the grinding solution to the human body is reduced.
Description
technical field [0001] The invention relates to a tissue grinder, in particular to a hand-held tissue grinder with rotary clamping position. Background technique [0002] A tissue grinder is an instrument for grinding tissue and making tissue homogenate, which is used to extract RNA, DNA or protein. The structural design of the existing tissue grinders on the market is unreasonable, and they are all manually inserted and pulled out, and the operation is complicated. Since the grinding objects are tissue cells, bacteria, etc., there may be pollution if they are directly inserted and removed by hand, or auxiliary tools are inserted and removed, but the operation process is too cumbersome, and there are also secondary pollutions. Therefore, it is urgent for technicians to solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotary clamping hand-held tissue grinder with simple structural desi...
