[0040] Specifically, the trigger assembly includes a centrifugal groove 16, a traction spring 17, and a centrifugal sealing block 18. The centrifugal groove 16 is opened on the inner wall surface of the liquid storage tank 15. The centrifugal sealing block 18 is movably installed on the inner wall of the centrifugal groove 16.

[0041] In this embodiment, the centrifugal sealing block 18 is provided to change the positional relationship of the centrifugal sealing block 18 mainly by utilizing the centrifugal force exerted on the centrifugal sealing block 18, thereby controlling the release of the polishing liquid inside the liquid storage block 9, and applying the polishing liquid to the surface of the hardware to achieve a better polishing effect.

[0042] Specifically, the storage component includes a liquid storage block 9 and a sealing cover 28. The liquid storage block 9 is fixedly mounted on the back of the polishing seat 4.

[0045] In this embodiment, the rubber scraper 21 is provided to clean the impurities and polishing liquid remaining on the surface of the hardware after polishing, so as to ensure the cleanliness of the surface of the hardware tool.

[0046] Specifically, the telescopic assembly includes a limit groove 19, a telescopic column 22, an auxiliary spring 23, a top block 24, a positioning spring 25, and a limit block 27. The limit groove 19 is opened on the front side of the rotating shaft 2, and the telescopic column 22 is movably installed on the inner wall of the limit groove 19.

[0047] In this embodiment, the top block 24 is mainly used to control the position of the cleaning seat 5. The cleaning seat 5 is driven to move toward the direction close to the grinding motor 1 by squeezing the top block 24. The cleaning seat 5 is brought into contact with the hardware surface by releasing the top block 24, thereby cleaning the impurities on the hardware surface.

[0048] Specifically, the plug-in assembly includes a collection box 26 and an adsorption sponge 29. The collection box 26 is plugged into the outside of the cleaning seat 5, and the adsorption sponge 29 is fixedly installed on the inner wall of the collection box 26. A plug hole adapted to the collection box 26 is opened in the middle of the cleaning seat 5, wherein the collection box 26 and the guide hole 20 are parallel to each other, and a pull rod is arranged on the outside of the collection box 26.

[0049] In this embodiment, the collection box 26 is provided to facilitate cleaning of the impurities scraped off by the rubber scraper 21 , wherein the polishing liquid is absorbed and stored by the adsorption effect of the adsorption sponge 29 .

[0050] Working principle: When in use, first fix the hardware to be polished, and then energize the polishing motor 1 through external equipment. At this time, the polishing motor 1 drives the rotating shaft 2 to rotate, and the polishing seat 4 and the cleaning seat 5 are fitted with the surface of the hardware to be polished. At this time, the rubber scraper 21 on the surface of the cleaning seat 5 is first fitted with the polishing surface, and the frosting sheet 6 on the front of the polishing seat 4 is separated from the polishing surface. When polishing is required, a certain pressure is applied to the polishing motor 1 through an external hydraulic rod, and the polishing motor 1 is modulated to adjust the polishing speed. At this time, the top block 24 is subjected to a certain pressure and moves along the limit groove 19 The inner wall level of the polishing seat 4 is contracted. At this time, the telescopic column 22 is contracted under the drive of the top block 24, thereby further driving the cleaning seat 5 to contract, so that the rubber scraper 21 on the front of the cleaning seat 5 is separated from the polishing surface. The telescopic column 22 compresses the positioning spring 25 during the compression process and stores a certain elastic potential energy. Due to the external pressure, the cleaning seat 5 is separated from the polishing surface. At this time, the frosting sheet 6 on the front of the polishing seat 4 contacts the polishing surface. Since the polishing seat 4 rotates under the drive of the rotating shaft 2, the hardware surface is polished. When the polishing seat 4 rotates, the centrifugal sealing block 18 is affected. The centrifugal force acts and moves outward along the inner wall of the centrifugal groove 16. Since the centrifugal force on the centrifugal sealing block 18 in the grinding state is greater than the mortgage force of the traction spring 17, the centrifugal sealing block 18 is separated to the digging side along the inner wall of the centrifugal groove 16, thereby further releasing the seal of the centrifugal sealing block 18 on the liquid guide tube 10. At this time, the polishing liquid stored in the liquid storage block 9 flows into the liquid storage tank 15 through the liquid guide tube 10, and flows into the inside of the grinding sheet 6 through the hole on the back of the mounting seat 8. At this time, the polishing liquid inside the grinding sheet 6 is evenly discharged from the leakage hole 7 under the action of the centrifugal force, and under the smearing of the grinding sheet 6, the grinding liquid in the grinding sheet 6 is discharged from the leakage hole 7. The polishing liquid is evenly distributed on the surface of the hardware, so that the sanding sheet 6 can polish the surface of the hardware more fully. The polishing liquid is poured into the liquid storage block 9 before polishing and sealed by the sealing cover 28. When the sanding sheet 6 finishes polishing the surface of the hardware, the rotation speed of the polishing motor 1 is reduced. At this time, the centrifugal force exerted on the centrifugal sealing block 18 inside the polishing seat 4 is less than the traction force of the traction spring 17, so that the traction spring 17 drives the centrifugal sealing block 18 to shrink inward along the inner wall of the centrifugal groove 16. At this time, the centrifugal sealing block 18 seals the liquid guide tube 10, so that the polishing liquid inside the liquid storage block 9 no longer flows out.

[0051] When it is necessary to clean the polishing fluid and impurities on the surface of the hardware, a certain amount of pressure is released on the polishing motor 1 through the external hydraulic rod. At this time, the pressure on the top block 24 is reduced. At this time, the limit block 27 and the auxiliary spring 23 perform a reset movement under the action of their own elastic potential energy. At this time, the positioning spring 25 and the auxiliary spring 23 drive the telescopic column 22 to reset to the initial position outward, thereby further driving the cleaning seat 5 to reset. At this time, the rubber scraper 21 on the front of the cleaning seat 5 fits with the polished hardware surface. Since the rotating shaft 2 is in a low speed state at this time, The rubber scraper 21 is driven to make a circular motion to scrape the polishing liquid on the surface of the hardware. During the scraping process, the polishing liquid is subjected to the centrifugal force and is thrown out along the surface of the rubber scraper 21, and flows into the collecting box 26 through the guide hole 20 on the front of the cleaning seat 5. Since the adsorption sponge 29 has an adsorption effect, the polishing liquid is absorbed and stored. When the cleaning is completed, the grinding motor 1 is powered off, so that the collecting box 26 is pulled out from the outside of the cleaning seat 5, so that the adsorption sponge 29 is taken out for cleaning.
