A Gravity Adaptive Scribing Mechanism

Abstract

To solve the problems of manual ruling in the prior art that the biological safety is low, the operation is non-standard, the randomness of manual operation is large, the labor cost is high, the efficiency is low, and a culture medium is easy to scratch, the invention provides a gravity self-adaptive ruling mechanism which comprises a fixing end, a locking sleeve, a connecting end and a ruling pen, wherein the fixing end adopts a rigid structure; the top of the fixing end is adaptive to an external mechanical moving mechanism; the top of the locking sleeve adopts an upwards opening sleeve structure, and is fixed to the bottom of the fixing end in a coordinated manner; the bottom of the locking sleeve adopts a downwards opening sleeve structure; a platform bulging in the inner diameter direction is arranged at the bottom of the locking sleeve; a positioning block of which the section is T-shaped is arranged at the top of the connecting end; the top of the connecting end is in positioning coordination with the platform; the bottom of the locking sleeve is also in interference fit with the rod part of the connecting end; an opening is formed in the top of the ruling pen, and tightly clamps the bottom of the connecting end. The work efficiency is high, the operating process is standardized and mechanized, and the culture medium is prevented from being scratched.

Description

technical field [0001] The invention relates to a gravity adaptive marking mechanism. Background technique [0002] The marking mechanism is a very important instrument in the inoculation, cultivation, isolation and detection of microorganisms. At present, microbial inoculation, cultivation, separation and detection are all carried out manually, and the specific operation steps are as follows: [0003] (1) The experimenter holds the sampling loop for manual sterilization; [0004] (2) The experimenter dips the microbial sample and gently injects a small amount of microbial sample on the surface of the glass culture medium; [0005] (3) Streak lines on the surface of the culture medium, so that the mixed microorganisms or different cells in the same microbial population can be diluted by dividing lines to obtain more independently distributed single cells, which grow and reproduce into single colonies after culture. [0006] Obviously, the existing manual marking methods h...
