The connection of the track 113 to the cylinder 12: 'only' when the air duct 13 is docked with the steam red 12, the ring 14 must be tightly contacted with the steam red 12, so that the problem of docking accuracy is not only overcome. It is also necessary to ensure the consolidation effect with the steam m, the size of the fine <requires the car father, and the inconvenience of assembly. [New content] Sequence Therefore, the purpose of the present invention and the pneumatics for improving the airtightness effect are to provide an air guiding device capable of simplifying the assembly process. Thus, the pneumatic tool has a casing and a steam red assembled in the casing. The casing has an intake passage connecting the air pressure source. The cylinder has a % around an X-axis and defines a gas chamber. The cylinder wall and a passage formed in the cylinder wall and communicating with the air chamber along a Z-axis direction, the air guiding device of the present invention comprises a wind deflector and an air guiding duct group. The air deflector has a ring seat fixed to the steam red, and a hole passing through the ring seat and communicating with the channel. The air guiding group has a wind guide disposed between the air guiding channel and the air inlet channel, and is disposed between the air guiding tube and the ring seat, between the air guiding tube and the housing At least two washers. The beneficial effects of the novel are: using the assembly method of the socket, and matching. The wind-proof and pressing effect of the quilt and other gaskets effectively enhance the airtightness in the case of simplifying the assembly process. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 2, 3' and 4, a preferred embodiment of the novel wind deflector is mounted in a pneumatic tool 2. The pneumatic tool 2 has a housing 21 and a vapor red 22 assembled in the housing 21. The housing 21 has a housing 211, a grip 212 adjacent to the housing 211, and a housing formed in the grip 212 and connected to a pneumatic source. The cylinder 22 is assembled in the housing 21 The seat 211 has a cylinder wall 221 that defines a plenum 220 and a valve seat 223 that defines a passage 222 in the cylinder wall 221 . The passage 222 communicates with the plenum 22 。. The air guiding device comprises a wind deflector 3 and an air guiding duct group 4 respectively. The air deflector 3 has a ring seat 31 fixed to the end of the valve seat 223, a hole 32 extending through the ring seat 31 and communicating with the passage 222, and a first edge 33 formed on the inner surface of the ring seat 31. The tunnel 32 has an angle of inclination with the z-axis. The air guiding duct group 4 has an air guiding duct 41 and two pairs of washers 42. The air duct 41 is disposed between the tunnel 31 of the air deflector 3 and the intake passage 213 of the grip 212 and has a first end surface 411 and a second end surface 412 formed at opposite ends. The first end face 411 abuts against the step edge 3 3 of the wind deflector 3. The second end surface 412 faces the intake flow passage 213 and greets the air flow. The stiffeners 42 are disposed on an outer surface of the air duct 41 and adjacent to the first and second end faces 411, 412, respectively. When assembling, the air duct 41 is simply placed between the air passage 32 of the air guiding disc 3 and the air inlet passage 213 of the grip 212, so that the air is placed in the air guiding passage. The gaskets 42 between the tube 41 and the ring seat 31 and between the air duct 41 and the grip 212 achieve an airtight effect. It is also worth mentioning that the air duct 41 is assembled in a penetrating manner, and the eye item 42 is used to achieve the tightness of the eye, and the air flow path is followed during the process of conveying the air flow. The upwardly flowing airflow of 213 forms an upward thrust on the second end surface 412' of the air duct 41, pushing the air duct 4 to be deeper into the tunnel 32 of the air deflector 3, to be blocked The edge 3 3 is stable to the positioning. According to the above description, the air guiding device of the pneumatic tool of the present invention has the following advantages and effects: M427219 The present invention mainly utilizes the assembly method of the sleeved b ,, and connects the air guiding tube 41 ' with the mats. The P wind and the pressing effect of the 42 effectively improve the airtightness effect in the case of simplifying the assembly process, thereby not only reducing the size (four) degree requirement of the air guiding disc and the air guiding duct 4 when being sleeved. Moreover, it is possible to use the pushing effect of the air dust to enhance the stability of the wind tunnel face s 41 and the wind deflector 3. The above-mentioned ones are only the preferred embodiments of the present invention, and when it is not possible to limit the implementation of this (4), that is, the simple equivalent change made by the patents and the new type of 垅明内谷And modifications are still within the scope of this new patent.
