Specifically, the pulling rod 33 pulls the mounting seat 34 to swing up and down in a reciprocating manner, when the cleaning sheet 4 inclines upwards to the position shown in fig. 16-a, the bottom of the cleaning sheet 4 contacts the inner wall of the test tube 6 and pushes the sliding seat 35 to move towards the right side, so that the bottom of the cleaning sheet 4 scrapes off residues attached to the inner wall of the glass;

when the cleaning sheet 4 is vertically attached to the inner wall of the glass of the test tube 6 to the position shown in fig. 16-b, the cleaning sheet 4 is bounced leftwards under the reset action force of the elastic piece 363 of the sliding seat 35, the whole plane of the cleaning sheet 4 is contacted and attached to the inner wall of the glass of the test tube 6, small-amplitude impact is carried out on the inner wall of the glass of the test tube 6, vibration is generated between the inner wall of the glass and residues, and the residues which are burnt and attached to the inner wall of the glass are impacted to generate cracks, so that the surfaces of the inner wall of the glass are peeled;

when the cleaning sheet 4 is inclined downwards to the position shown in fig. 16-c, the top of the cleaning sheet 4 contacts the inner wall of the test tube 6 and pushes the sliding seat 35 to move towards the right side, so that the residue attached to the inner wall of the glass is scraped by the top of the cleaning sheet 4, the cleaning is more thorough, and the phenomenon of residue of the attached matter is eliminated.

The foregoing is a preferred embodiment of the invention and it will be apparent to those skilled in the art that variations and modifications may be made without departing from the inventive concept and these are intended to be within the scope of the invention.
