Description of the invention: [Technical field to which Yuming belongs], the invention relates to a pneumatic type with dual exhaust ports: L is a pneumatic tool that can be simultaneously exhausted on both sides when using a moving tool.曰[Prior Art], body-in-gas supply, gas: 排气 gas exhaust vents' and when the pneumatic tool is driven, the gentleman enters the air tool and drives the pneumatic tool port to exhaust the outside After that, the amount of gas is converted into exhaust gas, and the flow rate required by the air pressure of the exhaust gas type 3 type moving tool is increased by a smaller pneumatic tool. Therefore, the intake air size = the required gas supply, and the expansion of the intake port to change the displacement of the exhaust port must also decrease with the increase of the intake air amount. The size of the nipple is to increase the displacement and avoid the driving efficiency. The pneumatic tools seen on the surface, when the displacement of the pneumatic tool increases, and the pressure gas is discharged through a single exhaust port, often leads to exhaust. The noise is raised and the sound of the sharp ear is generated. Although the pneumatic tool with the sound-absorbing cotton has been added, this situation is forgiven. Therefore, how to use the pneumatic tool with large displacement is invented: the factory problem is the invention The focus of the solution. A double-row old = main purpose 'is to solve the above problems - a pneumatic tool for venting the nipple, which can be used by a pneumatic tool at the same time: 5 200829366 Side exhaust gas at the same time to reach a large displacement Use the dispersible exhaust to reduce the effect of σ. For the foregoing purposes, the present invention is characterized in that an air inlet is provided in a casing, a pneumatic motor, an air intake switch for controlling the rotation of the air motor, and an actuating portion driven by the rotation of the air motor. The casing has two ventilating motors on the two sides and an exhaust port for exhausting the air from the air motor, both of which are symmetrical and perpendicular to one of the drive shafts of the air motor. The above and other objects and advantages of the present invention will be readily understood from Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] Please refer to Fig. 1 to Fig. 4, which shows the structure of the embodiment selected for the present invention, which is for illustrative purposes only and is not limited by this structure in the patent application. The embodiment provides a pneumatic tool with a double exhaust port, which is a ninety degree transmission pneumatic grinder. As can be seen from the figure, it has a casing 1 and a rear portion of the casing 1 is provided with a The air port 11 is provided with an air inlet switch 12 on one side, a air motor 13 in the middle of the housing 1, and a 90 degree intersection with the rotating shaft 131 of the air motor 13 in the front portion of the housing 1 to be driven. Grinding portion 14 . The high pressure gas can be controlled by the pressing of the intake switch 1 2, enters the air motor 13 to drive its rotation, and drives the grinding portion 14 to actuate. 6 200829366 The two sides of the casing 1 respectively have an exhaust port 2 that communicates with the air motor 13 and the outside world, which is exhausted after the air motor 13 is exhausted. In the present embodiment, the housing 1 has a space 3 communicating with the two exhaust ports 2 between the bearing housing 15 adjacent to the grinding portion 14 and in the housing 1 at the bottom of the air motor 13. There is a communication air passage 13 and a passage 4 of the space 3, and the two exhaust ports 2 are axially disposed on the outer body 1 of the bearing housing 15 , thereby showing that the air motor 13 is The passage 4 communicates with the space 3 between the casing 1 and the bearing housing 15 and communicates with the outside through the exhaust port 2 on both sides of the casing 1. In the embodiment, the exhaust ports 2 on both sides of the pneumatic grinder are respectively pivotally provided with a cover body 2 1 for rotation, and each cover body 2 1 is on one side of a king face 2 1 1 There are a plurality of vent holes 2 1 2 which can be rotated with the cover body 2, and the exhaust direction is changed. And a sound-absorbing cotton (not shown) for reducing exhaust noise is respectively disposed in the exhaust ports 2 on both sides of the casing 1, and is covered by the cover body 21 corresponding to each of the exhaust ports 2. The housing 1 is at one end of the grinding portion 14 adjacent to either side of the exhaust port 2 on both sides thereof, and perpendicular to the transmission axis 丄3 2 of the air motor 13, the axial direction is again due to work, and must be assisted The housing is held at one end of the grinding portion 14 to prevent the hand from blocking the grip 丄6 of the exhaust port 2. With the above structure, when the high-pressure gas enters from the air inlet 1 of the pneumatic grinder and then 'presses the pneumatic switch 1 2 of the air motor 13 via the control gas, the gas-driven air motor i 3 rotates, and the pneumatic grinder is driven. The grinding portion 14 of the front stage rotates, (4), the gas after the rotation of the driving air motor i 3 becomes the exhaust gas, which passes through the passage 4 7 200829366 at the bottom of the air motor 丨 3 , and then passes through the space 3 between the bearing housing 15 and the housing 1 . The exhaust ports 2 on both sides of the casing 1 are discharged to the outside. Therefore, it is not difficult to find that the main advantage of the present invention is that, by designing the exhaust ports 2 on both sides of the pneumatic grinder, when the amount of high-pressure gas exhaust is large, it can be discharged to the outside through the double exhaust port 2 to disperse Exhaust to reduce the noise generated by the exhaust and sharp squeaks. Of course, there are still many examples of the present invention with only minor changes in detail. Please refer to FIG. 5 to FIG. 6 , which are a second embodiment of the present invention, wherein the two exhaust ports 2 A are relatively perpendicular to the transmission axis 13 2 2 and are axially disposed on the channel 4 . Both sides of the casing 1 are so as to achieve the same effects as the first embodiment described above. The above description of the embodiments is intended to be illustrative of the invention, and is not intended to limit the scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects and is in accordance with the provisions of the Patent Law.
