に支障をきたしているのが実状である。 Conventionally, when using pneumatic tools such as air drills and air wrenches when performing sheet metal work on automobiles, it was often the case that the pneumatic tools were inserted into narrow spaces on the car body. Since the blowing direction of the exhaust air of the pneumatic tool in use cannot be adjusted, the actual situation is that dust, mud, etc. blown away by the exhaust air are sprayed onto the operator, causing trouble in the work.

に案出したものである。 In order to eliminate the above-mentioned disadvantages, the present invention has been developed to close the air outlet of a pneumatic tool with a closing fitting that is airtightly fixed to the tool body in an adjustable position, and to open a part of the closing fitting in a predetermined direction. The exhaust air is blown out to the outside through the blown-out nozzle,
An exhaust air jet direction adjusting device has been devised here, which allows the exhaust air jet direction to be adjusted in a desired direction according to the working posture by adjusting the fixing position of the closing fitting.

向にのみ噴出させることができる。 An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows an example in which the present invention is applied to a known air drill. A cylindrical closing fitting 12 with one end closed is screwed onto the air outlet 11 in an airtight manner. This closure fitting 1
2 has a plurality of jet holes 12a drilled in the radial direction only in a part of its peripheral wall, and one end is connected to the handle part 1.
It is biased outward by a coil spring 13 that is engaged with the lower end of the tool body 10, and is elastically fixed to the tool body 10 so that its position can be adjusted. In the figure, P 1 indicates an air supply passage, and P 2 indicates an exhaust passage. When using an air drill equipped with such a closing fitting 12, the opening direction of the nozzle hole 12a is adjusted as appropriate by screwing the closing fitting 12 forward and backward.
The exhaust air ejected from the air outlet 11 can be ejected only in a desired direction.

An annular closing fitting 22 with both ends 22b closed is fitted into an annular groove 21 provided at Oa so that its position can be adjusted in the rotational direction by its own elasticity. The closing fitting 22 has a plurality of ejection holes 22a radially bored in only a part of its peripheral wall, and covers an air outlet 23 opening in a part of the annular groove 21. In the figure, P 1 indicates an air supply passage, and P 2 indicates an exhaust passage. When using the air trench trench fitted with such a closing fitting 22, the nozzle hole 2 is closed by rotating the closing fitting 22.
Adjust the opening direction of air outlet 2a appropriately.
The exhaust air that is blown out from 3 can be blown out only in a desired direction.

高めることができる。 In summary, in the present invention, as exemplified in the above embodiment, the air outlet of a pneumatic tool such as an air drill or an air wrench is closed by the closing fittings 12 and 22 airtightly assembled to the tool body so that the position can be adjusted. The structure is characterized by the fact that exhaust air is blown out from a blowout hole opened in a predetermined direction in a part of the peripheral wall of the metal fitting, which allows the worker to fix the blocking metal fitting according to his or her working posture. By adjusting the position and freely changing the ejection direction of the discharged air, work can be easily performed and work efficiency can be improved.
