[0032] The cleaning mechanism 2 includes two guide posts 21, designed to provide good support. The two guide posts 21 are fixedly connected to the outer sides of the base 1. Each guide post 21 is fitted with a return spring 22, designed to provide good return capability. Compression of the return spring 22 enables rapid return, and the guide posts 21 provide good guidance for the return spring 22, preventing it from shifting. A sliding block 23 is fixedly connected to one side of each guide post 21, designed to provide good sliding capability. Compression and extension of the return spring 22 drive the sliding block 23 to slide. A support assembly is fixedly connected to the top of the sliding block 23, including two support pillars 24, designed to provide good support. The two support pillars 24 are fixedly connected to the top of the sliding block 23. A transverse support rod 25 is fixedly connected to the adjacent outer side of each support pillar 24, providing good lateral support for the transverse support rod 25. The support assembly includes a brush 26 fixedly connected to the bottom of a horizontal support rod 25, a scraper 27 fixedly connected to the bottom of the horizontal support rod 25, and the outer side of the brush 26 located behind the scraper 27. A pull bracket 28 is fixedly connected to the bottom of the support assembly, designed to provide good pulling capacity. The brush 26 is fixedly connected to the bottom of the support assembly, allowing for cleaning of the backlight surface and preventing inspection errors. The scraper 27 is also fixedly connected to the bottom of the support assembly, allowing for... The solid particles adhering to the backlight surface are scraped off. A locking block 210 is slidably connected to the top of the base 1. Its design provides good sliding ability, allowing the locking block 210 to slide inside the base 1. A collection box 29 is fixedly connected to the outside of the locking block 210. Its design can sweep the dust and particles cleaned by the brush 26 and scraper 27 into the collection box 29. The outside of the locking block 210 is on the top front side of the base 1, and two sliding blocks 23 are on the outside side of the base 1, away from the locking block 210.

[0033] Reference Figure 2 and Figure 3The fixing mechanism 3 includes two placement slots 31, which are designed to provide good placement space. The two placement slots 31 are opened on the outer rear side of the base 1. The sliders 32 are fixedly connected inside the two placement slots 31. The sliders 32 can slide smoothly inside the placement slots 31 through the placement space provided by the placement slots 31. The two sliders 32 are fixedly connected to one side of the outer ...

[0034] Working Principle: When cleaning the backlight surface is required, the pull bracket 28 is first pulled, causing the sliding block 23 to slide along the guide post 21, while the return spring 22 is compressed. At this time, the brush 26 and scraper 27 move synchronously with the movement of the transverse support rod 25. The brush 26 first contacts the backlight surface, using its soft bristles to perform preliminary cleaning, removing dust and fine particles. Subsequently, the scraper 27 contacts the backlight surface, scraping away any adhering solid particles that the brush 26 failed to remove, further cleaning the backlight surface. Simultaneously, the locking block 210 slides on the top of the base 1, moving the collection box 29, allowing for installation and removal of the collection box 29. The opening of the collection box 29 is directly opposite the cleaning path of the brush 26 and scraper 27, sweeping the dust and particles cleaned by the brush 26 and scraper 27 into the interior of the collection box 29, thus collecting the waste generated during the cleaning process. After cleaning is complete, release the pull bracket 28. The return spring 22 extends under the action of elastic force, pushing the sliding block 23 to slide in the opposite direction along the guide post 21, driving the support assembly, brush 26, and scraper 27 back to their initial positions, completing one cleaning cycle. Throughout the process, the guide post 21 provides stable guidance for the movement of the return spring 22 and the sliding block 23, enabling the cleaning action to be completed smoothly and accurately.

[0035] When the phone backlight needs to be fixed, the sliding of the support block 34 causes the support rod 35 fixedly connected to its top to move accordingly. The movement of the support rod 35 causes the connecting rod 36 fixedly connected to its outside to move. The support of the connecting rod 36 is further transmitted to the pressing rod 37 fixedly connected to its outside, causing the pressing rod 37 to move towards the backlight. Finally, the pressing rod 37 applies pressure to the backlight, firmly fixing it to the base 1. Then, by sliding the slider 32 to drive the locking post 33 to slide inside the placement groove 31, the pressing rod 37 can be fixed. When it is necessary to release the phone backlight, the slider 32 is operated in the opposite direction, causing it to slide in the opposite direction within the placement groove 31. This process reverses the movement direction of the locking post 33, support block 34, support rod 35, connecting rod 36, and pressing rod 37, ultimately causing the pressing rod 37 to release the pressure on the backlight, thereby realizing the release and removal of the backlight.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
