[0048] Please refer to Figure 1 , Figures 4-5 The embodiment further includes the following on the basis of the above-mentioned embodiment 1.

[0049] The moving cleaning assembly;

[0050] The moving cleaning assembly includes vertical grooves 31, a group of moving blocks 32, connecting plates 33 and cleaning plates 36.

[0051] The vertical grooves 31 are arranged on both sides of one end of the body 11. The moving blocks 32 are slidingly connected in the vertical grooves 31. The connecting plates 33 are fixed between the inner side ends of the moving blocks 32. The cleaning plates 36 are located on the inner side surfaces of the connecting plates 33.

[0052] The vertical grooves 31 are used for the connection and movement of the moving blocks 32. The moving blocks 32 are used for the connection of the connecting plates 33. The connecting plates 33 are used for the connection of the cleaning plates 36. The cleaning plates 36 clean the identifier 12.

[0053] The vertical grooves 31 are located on both sides of the identifier 12. Two groups of magnetic blocks 34 are fixedly connected on one side of the body 11. The magnetic blocks 34 are respectively located on the outer side surfaces of the vertical grooves 31. The magnetic blocks 34 are attracted to the outer side ends of the moving blocks 32.

[0054] Two groups of springs 35 are fixedly connected between the connecting plates 33 and the cleaning plates 36.

[0055] The magnetic blocks 34 are used for being attracted to the moving blocks 32. When the moving blocks 32 are not used, they are attracted to the two magnetic blocks 34, so as to limit the connecting plates 33 and the cleaning plates 36.

[0059] Working principle:

[0060] When using the identifier 12, push the connecting plate 33 downward, so that the moving block 32 slides down in the vertical groove 31, prompting the connecting plate 33 to drive the cleaning plate 36 to move down through the moving block 32, and the cleaning plate 36 cleans the surface of the identifier 12 during the moving process;

[0061] At the same time, when the cleaning plate 36 moves down, the cleaning plate 36 abuts against the body 11, so that the cleaning plate 36 moves to the connecting plate 33 direction through the spring 35, prompting the cleaning plate 36 to be attached to the connecting plate 33, facilitating the movement of the connecting plate 33, so as to expose the identifier 12;

[0062] After using the identifier 12, push the connecting plate 33 upward, the connecting plate 33 moves upward through the moving block 32, and when it moves upward, the moving block 32 is respectively attracted to the corresponding magnetic block 34, the moving block 32 after magnetic attraction limits the connecting plate 33 and the cleaning plate 36, so that the connecting plate 33 protects the identifier 12;

[0063] The above steps can improve the functionality of the device.
