The end of the connecting plate 12 is fixedly connected to the rotating plate 5, and the rotating shaft 3 is connected to a positioning mechanism for positioning the rotating plate 5.

[0025] When it is necessary to clean the material inside the observation window 1, the handle 2 can be rotated to drive the rotating shaft 3 to rotate, thereby realizing the rotation of the rotating plate 5. The rotating plate 5 drives the rubber scraper 6 to rotate, so as to facilitate the cleaning of the material attached to the observation window 1. The spring 13 is always tightened on the rotating plate 5, so that the end of the rubber scraper 6 is firmly attached to the inside of the observation window 1, and the scraping effect is remarkable.

[0026] The scraping mechanism includes a rubber scraper 6, a scraper handle 7, and a plurality of positioning protrusions 20. The scraper handle 7 is connected to the end of the rubber scraper 6.

The positioning protrusion 20 is made of an iron material and has a certain adsorption force, so as to facilitate the connection between the rubber scraper 6 and the rotating plate 5 .

[0028] The cross-section of the connecting plate 12 is a regular polygonal structure, and the connecting plate 12 is slidably connected to the guide groove 14, which improves the stability of the movement of the connecting plate 12, that is, the movement of the rotating plate 5 is stable, and the rotation of the rotating shaft 3 can synchronously drive the rotation of the connecting plate 12, which is convenient for the rotation of the rotating plate 5 and the rubber scraper 6.

[0029] The spring 13 is located in the guide groove 14 , and both ends of the spring 13 are connected to the connecting plate 12 and the rotating shaft 3 .

[0030] The positioning mechanism includes an L-shaped plate 8, a fixed cylinder 9, a positioning column 10, an inner cavity 15, a second spring 16, and a pull rod 21. The two ends of the L-shaped plate 8 are connected to the rotating shaft 3 and the fixed cylinder 9.

At this time, the spring 2 16 is always in a compressed state. When the rotating plate 5 moves to an appropriate position, the bottom of the positioning column 10 is aligned with the positioning groove 11, and the compressed spring 2 16 drives the positioning column 10 to move downward, so that the bottom of the positioning column 10 is inserted into the positioning groove 11, thereby realizing the positioning and locking of the rotating plate 5, which is convenient for disassembly and assembly of the rubber scraper 6.
