[0024] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0025] like Figures 1 to 4 As shown, a precision sandblasting tool includes a pressing plate 1, four groups of butterfly bolts 2 are evenly arranged on both sides of the pressing plate 1, a lower plate 3 is arranged below the pressing plate 1, handles 31 are fixedly connected to both sides of the lower plate 3, and an adjusting mechanism is also included. The adjusting mechanism includes a plurality of slide grooves 11 arranged inside the pressing plate 1, a slide plate 13 is slidably connected inside the slide groove 11, two groups of sliders 12 are fixedly connected to the front and rear ends of the slider 13, and the sliding sliders 12 and the sliders 13 can adjust the opening area of ​​the sandblasting opening of the pressing plate 1.

[0026] Specifically, Figure 1 and Figure 4 As shown, a fixed platform 4 is provided below the lower plate 3, and four groups of positioning platforms 41 are fixedly connected at the corners of the fixed platform 4, the inner side of the positioning platform 41 is matched with the outer side of the pressure plate 1 and the lower plate 3, and two groups of fixed slide plates 42 are fixedly connected on both sides of the positioning platform 41, and two groups of lower slide grooves 43 matched with the two groups of fixed slide plates 42 are provided inside on both sides of the butterfly bolt 2, and two groups of upper slide grooves 44 matched with the two groups of fixed slide plates 42 are provided inside on both sides of the pressure plate 1, and the outer side of the fixed slide plate 42 is slidably connected with the inner side of the lower slide groove 43 and the upper slide groove 44.

[0027] When working, first pick up the lower plate 3 and place the lower plate 3 on the upper end of the fixed platform 4. Because the fixed slide plate 42 is slidably connected with the lower slide groove 43, after the lower plate 3 is placed on the upper end of the fixed platform 4, the fixed platform 4 fixes the lower plate 3. Because the positioning platform 41 is adapted to the lower plate 3, when the lower plate 3 is put in, the positioning platform 41 positions the lower plate 3, ensuring that when the lower plate 3 is put in, the longitudinal positions of the fixed slide plate 42 and the lower slide groove 43 are the same, thereby increasing the stability of the lower plate 3.

[0028] like Figures 1 to 4 As shown, four groups of butterfly bolts 2 are evenly arranged on both sides of the pressing plate 1, a lower plate 3 is arranged below the pressing plate 1, handles 31 are fixedly connected to both sides of the lower plate 3, and an adjusting mechanism is also included, the adjusting mechanism includes multiple groups of slide grooves 11 arranged inside the pressing plate 1, a slide plate 13 is slidably connected inside the slide groove 11, two groups of sliders 12 are fixedly connected to the front and rear ends of the slider 13, the sliding slider 12, and the slider 13 can adjust the opening area of ​​the sandblasting opening of the pressing plate 1, multiple groups of placement grooves 33 are arranged on the upper end of the lower plate 3, and multiple groups of placement grooves 33 are arranged on the lower end of the pressing plate 1, the placement grooves 33 inside the lower plate 3 are matched with the placement grooves 33 inside the pressing plate 1, the inner side of the placement grooves 33 is fixedly connected with a rubber pad 34, the outer side of the rubber pad 34 is provided with a hardware 32, the hardware 32 is matched with the rubber pad 34, and four groups of screw holes 21 matched with the butterfly bolts 2 are arranged on both sides of the lower plate 3, and the butterfly bolts 2 are rotatably connected to the screw holes 21.

[0029] During operation, after the lower plate 3 is fixed, the hardware 32 is first placed inside the placement groove 33. Because the rubber pad 34 is fixedly connected to the inside of the placement groove 33, the rubber pad 34 protects the hardware 32 while squeezing the hardware 32 to keep it fixed. Then, when all the hardware 32 are placed, the pressing plate 1 is covered. Because the fixed slide plate 42 is slidably connected to the upper slide groove 44, and the positioning platform 41 is slidably connected to the pressing plate 1, when the pressing plate 1 is closed, the problem of damage to the hardware 32 caused by operating errors during closing is reduced, and the scrap rate and defective rate are reduced. Then, After the pressure plate 1 is closed, the butterfly bolt 2 is screwed to fix the pressure plate 1 and the lower plate 3. The staff holds the handle 31 by hand, lifts the sandblasting fixture and puts it into the sandblasting chamber. According to different requirements for the hardware 32, the staff slides the slider 12 by hand, and the slider 12 drives the slide plate 13 to slide and adjust in the slide groove 11. After adjusting to the required position, the sandblasting chamber starts to sandblast the hardware 32, which is beneficial to shield the surface of the hardware 32 that does not need to be processed, protect and wrap the parts that do not need to be sandblasted, and reduce the time used in the sandblasting preparation stage.
