[0024] Figure 2 Figure 3 Figure 4
[0025] When dust and fingerprint mark wiping treatment is needed, the servo motor 120 can be started to drive the winding roller 130 to wind the pull rope 150, and then the pull rope 150 pulls the magnet 110 to slide, at this time, the metal frame 310 is affected by magnetic attraction and moves on the outside of the handle body 100 along with the magnet 110, and in the movement process, the frame-shaped scraper 320 can scrape the dust on the surface of the handle body 100.
[0026] As shown in the figure, the cleaning mechanism 300 further includes two frame-shaped scrapers 320, and the inner wall of the frame-shaped scraper 320 is in contact with the surface of the handle body 100; a magnet 110 is arranged inside the metal frame 310 of the handle body 100, the magnet 110 is magnetically connected with the metal frame 310, a servo motor 120 is mounted inside the handle body 100, an output shaft of the servo motor 120 is mounted with a winding roller 130 through a shaft coupling, and a pull rope 150 is mounted between the winding roller 130 and the magnet 110. Figure 3 Figure 4 As shown, the inner wall of the metal frame 310 is embedded with two support rollers in contact with the outer side of the handle body 100, and the inner part of the metal frame 310 is rotationally connected with two anti-skid rods 330, and an inclined traction rope 350 is installed between the front anti-skid rod 330 and the cotton plate 340.
[0027] During the movement of the metal frame 310, the support rollers cooperate with the anti-skid rods 330 to stabilize the movement of the handle metal frame 310, and the anti-skid rods 330 are in a rotating state, and when they rotate, the traction rope 350 will be continuously pulled, and at this time the top end of the cotton plate 340 will follow the movement of the traction rope 350 and adaptively move, which is in a swinging state. The cotton plate 340 in the swinging process wipes the front surface of the handle body 100 and the surface of the fingerprint sensor 200, reduces the occurrence of fingerprint residue, and ensures the sensitivity of the fingerprint sensor 200 in later use.
[0028] As shown in Figure 2 , the inner wall of the handle body 100 is provided with an elastic rope 140, one end of which is installed to the outer side of the magnet 110.
[0029] After each dust removal and mark wiping operation is completed, the servo motor 120 can drive the rewinding roller 130 to reverse and reset, at this time the magnet 110 is not affected by the traction of the pull rope 150, then the elastic rope 140 resets to reset the magnet 110, and in the resetting process, the frame-shaped scraper 320 and the cotton plate 340 can also be used again.
