Novel test tube brush

Abstract

The invention discloses a novel test tube brush which comprises a rotary brush, an operating rod and a driving assembly. The rotary brush comprises a sleeve, brushes are uniformly distributed on the outer side wall and the outer bottom surface of the sleeve, and a test tube cap is arranged at the upper end of the sleeve; a spiral groove is formed in the inner wall of the operating rod; the drivingassembly comprises a driving shaft, a rotary wheel, a fastening component and a non-slip component. The novel test tube brush has the advantages that only the operating rod needs to be easily pusheddown and pulled up, accordingly, the rotary brush can rotate at the high speed, test tubes can be cleared, good clearing effects can be realized, labor and the time can be saved, and the novel test tube brush is speedy and is high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical experiment supplies, in particular to a novel test tube brush. Background technique [0002] In the process of chemical experiments, test tubes are often used. After the test tubes are used, the test tubes will be cleaned. Cleaning will use a test tube brush, so the test tube brush has become an utensil that is often used in the chemical experiment process. The traditional test tube brush includes a brush rod and bristles. The brush rod is an iron wire with many neatly arranged and outwardly extending bristles. The bristle materials include nylon wire, fiber hair, pig bristle, abrasive wire, etc. The test tube brush protrudes into the test tube and uses bristles to rub against the test tube wall to clean the inner wall of the test tube. It has simple structure, convenient operation and low cost, so it is widely used. However, there are also some problems in such a test tube brush. In the cleanin...
