The port IV connect.
Further, above-mentioned a kind of composite material counter boring self-dust-suction tool, port I and port III are coaxially disposed, port
II with III orthogonal vertical of port I and port.
Further, above-mentioned a kind of composite material counter boring self-dust-suction tool, the filter device is by filter mantle, filtering
Layer and filter tip are constituted, and filter tip is equipped with several ventholes.
Further, a kind of above-mentioned composite material counter boring self-dust-suction tool, wedge-shaped pipe fitting are located at the outer rim in port III
With the gap of air circulation between filter mantle inner wall.
The beneficial effects of the utility model are: the utility model composite material counter boring self-dust-suction tool, guarantee can be just
Reach following two advantage under the premise of true counter boring: one, the exhaust gas that pneumatic tools exhaust outlet is utilized carries out absorption composite material
Counter boring dust facilitates the secondary use of wind regime, improves energy utilization rate, and answers caused by avoiding because of exhaust outlet air draft
Material dust is spread.Two, the utility model composite material counter boring self-dust-suction tool has reached counter boring and dust suction and can carry out simultaneously, mentions
High production efficiency, counter boring are just sucked away immediately after answer the generation of material dust, play very important protection to environment to human body.This
Utility model composite material counter boring self-dust-suction tool is applied in terms of composite material counter boring important meaning.

Specific embodiment
Embodiment
As Figure 1-Figure 4, a kind of composite material counter boring self-dust-suction tool, by dust exhaust apparatus 10, Wind direction changing device 20,
Filter device 30 and suction pipe 40 are constituted.
As shown in Fig. 2, dust exhaust apparatus 10 is made of U-shaped main body 11, the closed end of U-shaped main body 11 is equipped with for being inserted into counter boring
The drill bit bore 12 of drill bit, the side wall of U-shaped main body 11 are equipped with the port IV 13 connecting with suction pipe 40.
As shown in figure 3, the tool of Wind direction changing device 20 is there are three port, port I 21 is filled by suction pipe 40 and dust suction
10 connection of port IV 13 is set, port II 22 is connect with the air draft port of socket drill, and port III 23 is connect with filter device 30.End
Mouth I 21 and port III 23 are coaxially disposed, and port II 22 is vertical with the axis vertical take-off of port I 21 and port III 23 in position.Wind
The internal wedge-shaped pipe fitting 25 with through channel 24 is equipped with into conversion equipment 20, wedge-shaped 25 one end of pipe fitting is fixed on port I 21
On 20 inner wall of Wind direction changing device of side, the other end is slightly protruded into port III 23.
Wind direction changing device passes through the flow direction that wedge-shaped pipe fitting controls air-flow, and the port form of Wind direction changing device is three way type
Design feature, the port being connect with socket drill exhaust port in position with another two port orthogonal vertical.
