[0026] Furthermore, such as Figure 2 As shown, the bottom of the first connecting pipe 15 is connected to a second connecting pipe 2; the end of the second connecting pipe 2 away from the drill body 1 is connected to a threaded pipe 21; the end of the threaded pipe 21 away from the second connecting pipe 2 is connected to a first connecting plate 22; a pair of spring columns 23 are fixedly connected to the side wall of the first connecting plate 22 away from the threaded pipe 21; a telescopic collecting pipe 24 is fixedly connected to the end of the spring column 23 away from the first connecting plate 22; the telescopic collecting pipe 24 and the threaded pipe 21 are interconnected; during operation, the middle part of the telescopic collecting pipe 24 is corrugated; multiple sets of spring columns 23 can push the telescopic collecting pipe 24 to fit against the processing wall, and the spring columns 23 can collect dust; the overall device increases the dust suction range of the suction pipe 16; reduces the occurrence of dust rolling down the wall; and the overall device improves the cleanliness of the working environment.

[0027] Furthermore, such as Figure 2-3 As shown, a threaded rotating post 3 is threadedly connected to the outer wall of the threaded pipe 21; a limiting collar 31 is rotatably connected to the outer wall of the threaded rotating post 3; a first limiting post 32 is slidably connected to the inner side of the limiting collar 31; the first limiting post 32 is connected to the side wall of the second connecting pipe 2; a pair of connecting ropes 33 are fixedly connected to the side wall of the limiting collar 31 away from the second connecting pipe 2; a rotating plate 34 is rotatably connected to the side wall of the telescopic collecting pipe 24; the rotating plate 34 is connected to the connecting ropes 33; [Working] When the drill body 1 is not in operation, the first limiting post 32 restricts the movement range of the limiting collar 31 by rotating the threaded rotating post 3.

The sealing tube 45 is installed at the end of the storage box 13 away from the suction pipe 16, allowing the storage box 13 to operate normally. The operator can move the second connecting plate 41 outward through the second limiting post 4, thereby causing the sealing post 44 to disengage from the inside of the expansion tube 43, and the sealing circular plate 46 to enter the inside of the storage box 13. The sealing circular plate 46 can seal the end of the storage box 13 away from the suction pipe 16. At this time, the drill body 1 is started, and the output shaft 11 drives the transmission belt 110 to drive the fan blade column 17 to exhaust the inside of the storage box 13. Because the sealing circular plate 46 seals one end of the storage box 13, the dust inside the storage box 13 can be discharged to the outside through the inside of the expansion tube 43.

[0031] Furthermore, such as Figure 4 As shown, the end of the second limiting post 4 away from the storage box 13 is fixedly connected to the limiting plate 7; during operation, the limiting plate 7 can restrict the movement range of the second connecting plate 41, thereby reducing the occurrence of the second connecting plate 41 falling off the second limiting post 4; the overall device improves the stability of the second connecting plate 41 during long-term operation.

[0032] Working principle: During operation, the inner side of the scraper 19 is centrally located and frame-shaped. The operator can install the drill bit at the drill bit clamping assembly 12. Starting the gun drill body 1 causes the output shaft 11 and drill bit clamping assembly 12 to rotate. The rotating output shaft 11 drives the fan blade column 17 to rotate via the transmission belt 110. The rotating fan blade column 17 uses the suction pipe 16 to suction dust from the area being processed by the drill bit. Dust is then drawn into the storage box 13 through the fan blade column 17 and the inner side of the first connecting pipe 15, filtered by the filter plate 14, and finally discharged outwards through the cleaning air pipe 18. The operator can collect and process the cleaning air through the cleaning air pipe 18. When cleaning the surface of the filter plate 14 is required, the scraper 19 is moved from the storage box... Pulling out of the box 13, the scraper 19 can concentrate the impurities blocked by the filter plate 14 inside and discharge them to the outside; the overall device reduces dust splashing at the processing area, preventing impurities in the dust from clogging the heat dissipation holes of the gun drill body; the overall device improves the cleanliness of the working environment; during operation, the telescopic collection pipe 24 is corrugated in the middle; multiple sets of spring columns 23 can push the telescopic collection pipe 24 to fit against the processing wall, and the spring columns 23 can collect dust; the overall device increases the dust suction range of the suction pipe 16; reduces the occurrence of dust rolling down the wall; the overall device improves the cleanliness of the working environment; during operation, when the gun drill body 1 is not working, by rotating the threaded rotating column 3, the first limiting column 32 engages with the limiting collar. The movement range of 31 is limited. The rotating threaded column 3 can drive the limiting collar 31 to move towards the second connecting pipe 2 through the first limiting column 32. The connecting rope 33 can drive the rotating plate 34 to flip, and the rotating plate 34 can seal the top of the telescopic collection pipe 24. The overall device reduces the occurrence of external impurities directly entering the telescopic collection pipe 24 when the drill body 1 is not working. During operation, because the sealing sleeve 45 is hollow and is installed at the end of the storage box 13 away from the dust suction pipe 16, the storage box 13 can work normally. The operator can move the second connecting plate 41 to the outside through the second limiting column 4, so that the sealing column 44 is disengaged from the inside of the expansion pipe 43 and the sealing circular plate 46 enters the storage box 13. On the side, the closed circular plate 46 can seal the end of the storage box 13 away from the dust suction pipe 16; at this time, the gun drill body 1 is started, and the output shaft 11 drives the transmission belt 110 to drive the fan blade column 17 to exhaust the inside of the storage box 13. Because the closed circular plate 46 seals one end of the storage box 13, the dust inside the storage box 13 can be discharged to the outside through the inside of the expansion pipe 43; the whole device improves the cleanliness inside the storage box 13 and reduces the occurrence of a large amount of impurities accumulating inside the storage box 13; during operation, when the rotating plate 34 seals the telescopic collection pipe 24 through the connecting rope 33, the first magnetic plate 5 and the second magnetic plate 51 attract each other due to magnetic force, thereby achieving the effect of assisting in sealing the top of the telescopic collection pipe 24;During operation, the support plate 6 and support ring 61 support the middle of the cleaning air pipe 18, thereby reducing the load at the connection between the cleaning air pipe 18 and the storage box 13, and improving the stability of the cleaning air pipe 18 during long-term operation. During operation, the limiting plate 7 restricts the movement range of the second connecting plate 41, thereby reducing the possibility of the second connecting plate 41 falling off the second limiting post 4; the overall device improves the stability of the second connecting plate 41 during long-term operation.
