Abstract

The utility model relates to a test tube brush which can be changed arbitrarily with the shape of the bottle body. The test tube brush is equipped with a hand-held rod. The bottom of the handle rod is connected with multiple brush rod heads with bristles. The middle part of the brush rod head is hinged to a support rod, and the other end of the support rod is hinged to the bottom of the operating rod with a sleeve hole. At the end, the operating rod is set on the handle rod through the sleeve hole, and the operating rod is used to slide up and down on the handle rod to achieve the purpose of opening and closing the head of the brush rod; The utility model is convenient to use, and can change the shape of the test tube container arbitrarily according to the shape of the test tube container to adapt to cleaning while being able to clean the test tube container.

Description

A test tube brush that can be changed arbitrarily according to the shape of the bottle body

technical field

The utility model relates to a test tube brush, in particular to a test tube brush which can change arbitrarily with the shape of the bottle body.

Background technique

At present, it is known that people use a variety of test tubes and liquid containers in the experimental process. After use, they will encounter problems when using a test tube brush to clean these test tubes. Due to the different shapes of various test tubes, the test tube brush cannot It is completely suitable for the test tube used and cannot be cleaned, which will bring errors to the next test and reduce the accuracy of the test.

Contents of the invention

In order to solve the problem that the existing test tube brush cannot adapt to various shapes of test tube containers, the utility model provides a test tube brush that can change arbitrarily with the shape of the bottle body. The test tube brush that can change arbitrarily with the shape of the bottle body is simple in structure, easy to use, and While cleaning the test tube container, it can also change its shape arbitrarily according to the shape of the test tube container to adapt to cleaning.

The technical scheme adopted by the utility model to solve the technical problem is: the test tube brush which can be changed arbitrarily with the shape of the bottle body includes: a hand-held rod, an operating rod, a support rod, and a brush head; the test tube brush which can be changed arbitrarily with the shape of the bottle body The brush is equipped with a handle bar, the bottom of the handle bar is connected with a plurality of brush bar heads with bristles, the middle part of the brush bar head is hinged with a support bar, and the other end of the support bar is hinged to the bottom end of the operating bar with a sleeve hole , the operating rod is set on the handheld rod through the sleeve hole, and the operating rod is used to slide up and down on the handheld rod to achieve the purpose of opening and closing the brush head. container for cleaning.

The beneficial effect of the utility model is that the test tube brush which can be changed arbitrarily according to the shape of the bottle body has a simple structure and is convenient to use. While cleaning the test tube container, it can also change its shape arbitrarily according to the shape of the test tube container to adapt to cleaning.
