Equipment for uniform-speed sample application on gene engineering by utilizing clamping force

Abstract

The invention relates to the technical field of gene engineering, and discloses equipment for constant-speed sample application on gene engineering by using clamping force; the equipment comprises a body, a positioning ring is fixedly connected to the inner bottom wall of the body, a steel pipe is inserted into the positioning ring, and a rotating gear is movably connected to the upper part of thefront surface of the steel pipe. According to the equipment for uniform-speed sample application on gene engineering by utilizing clamping force, a rotating disc is driven to rotate anticlockwise bya hand; a rotating gear is meshed with a transmission gear; when the rotating disc rotates, under the action of the transmission gear, and a core rod rotates clockwise under the linkage action; threads matched with the core rod are arranged on a metal part, when the core rod rotates, and the metal part ascends under reverse acting force; the metal part is fixedly connected with a lifting block, and then the lifting block is used in cooperation with a mounting base, so that the structure has the height adjusting function, and the problem that the height of a clamp cannot be adjusted is solved.

Description

technical field [0001] The invention relates to the technical field of genetic engineering, in particular to a device for spotting genetic engineering at a uniform speed by using clamping force. Background technique [0002] Genetic engineering, also known as gene splicing technology and DNA recombination technology, is based on molecular genetics and modern methods of molecular biology and microbiology, and constructs hybrid DNA in vitro by combining genes from different sources according to a pre-designed blueprint. Molecules are then introduced into living cells to change the original genetic characteristics of organisms, obtain new varieties, and produce new products. Genetic engineering technology provides a powerful means for the study of gene structure and function, and is an indispensable biological technology. [0003] Test tubes are usually used in genetic engineering testing or experiments. The existing genetic engineering test tube fixtures do not have the abili...
