When cleaning, a large amount of sediment may deposit at the bottom of the instrument. At present, a cleaning brush is usually used for cleaning. However, the various types of brushes in the laboratory cannot meet the purpose of quickly and completely cleaning the instruments. There are usually the following problems: 1) the existing brush is usually inserted horizontally (i.e. the angle between the brush and the brush rod is perpendicular), the brush is easy to fall off and damage the instrument; 2) for round-bottomed instruments such as flasks, the cleaning of the round bottom is insufficient and difficult; 3) the applicability of the brush is poor, and a corresponding brush needs to be purchased separately for different types of test tube flasks and the like.

[0019] 1. By setting the threaded connection relationship between the sleeve and the rod sleeve, the position of the sleeve relative to the rod body can be adjusted when the sleeve is rotated relative to the rod sleeve. By setting the driving mechanism, the sleeve is driven to rotate under the action of the telescopic rod. Due to the existence of the telescopic rod, the conflict between the sleeve being driven to rotate and the sleeve position adjustment is avoided. Since the position of the sleeve can be adjusted, the coverage of the bristles by the sleeve can be adjusted. When it is necessary to insert into the instrument, the bristles are completely covered by the sleeve, and the brush can be better inserted into the instrument port. For test tube type instruments, adjust the position of the sleeve to expose a small part of the bristles. The small part of the bristles is spread at the bottom of the test tube under the action of an external force, and the middle part of the bristles can cover the bottom of the test tube. With the help of the small part of the bristles, the bottom of the test tube is cleaned. For round-bottom flask type instruments, adjust the position of the sleeve to expose most of the bristles. Most of the bristles are spread at the bottom of the flask under the action of an external force, and the middle part of the bristles can cover the bottom of the flask, thereby facilitating cleaning of the bottom of the flask. By the above-mentioned mode, the vertical insertion of the bristles is adopted, and the sleeve that can adjust the position is used to adjust the exposure degree of the cleaning part of the vertical insertion of the bristles. On the one hand, the applicability to different instruments is improved, the frequency of replacing cleaning tools is reduced, the cleaning convenience is improved, and the work efficiency is improved. On the other hand, for round-bottom instruments, the bristles are spread to cover the round bottom, thereby facilitating cleaning. Furthermore, since the middle part of the bristles contacts the instrument during cleaning, damage to the instrument is reduced. Finally, the manual and electric combination is adopted, the initiative of manual work is retained, the convenience of electric tools is retained, and the additional research and development time burden of researchers is reduced.
