The two-valve system is sleeved on the outside of the first valve body and communicates with the cylinder block, and the driving rod is driven to rotate the first intermediate body relative to the second intermediate body. Change; the flow into the side of the cylinder group - '丄, 瑕 * - switch the rotor to turn into the second: = airflow direction, although the group of components can be provided more and more complex: = the effect of the locking operation 'but the switching time And the difficulty of the cause; and the "cost of manufacturing" will also increase the group skirt. In addition, as shown in the national switch No. 319346, the rotating structure of the κ κ moving tool and the commutation room: Γ: The structure is connected to the pneumatic tool, wherein the control handle is laterally movable to be rotatable relative to the housing, and the control cylinder is coupled with the control handle. The outside of the moving barrel and the gas, the 纟 are set at the turn f, so that the turn The cylinder can be opposite to the direction of the square air cylinder group of the control== control lever, although the effect of switching the rotor i?夂"1 flow into the operation can be provided, but the rotation is turned to retract or lock Will increase the cost of manufacturing, it will increase by two more and more complex, not only the improvement.,, loading time and difficulty, sincerely f content of the invention J in order to improve the above (4) tool structure and operational defects and no 201236825 Foot, the object of the present invention is to provide a pneumatic work that is easy to assemble and reduce cost and:::: exchange, accurate operation 'based on the above purpose, the direction switching device of the present invention. It is provided that the inner=:Γ switching device is installed in the housing of the pneumatic tool and is in the position of the side; the lower side of the cylinder group, the switching handle and a reversing room, wherein: the gas direction switching device is provided with a cylinder (four) :=The handle k can be horizontally movably sleeved in the housing and located in the cylinder group. The two ends of the switching handle respectively extend out of the housing, and the switching handle is disposed on the rear side of the housing. In the middle section, there is a card arm in the direction of the gas red group. The clamping arm is provided with a hole at a rear end different from the switching handle; and the D-switching valve is detachably coupled with the switching handle and rotatably disposed in the housing of the pneumatic tool and The cylinder group is in communication, the reversing chamber is a hollow cylinder. The reversing chamber is disposed in the intake pipe of the casing and is in the position of the casing. Above the inlet valve, the reversing valve is on the outer surface. The middle portion is eccentrically provided with a coupling column combined with the material arm opening hole, and the reversing portion is convexly provided with a valve i located below the cylinder group, and the valve seat is provided with a valve The cylinder block is rotating the air passage or reversing the valve hole through which the air passage communicates. Progressively, the Leica arm is integrally formed at the middle of the rear side of the switching handle. Further, the switching handle is provided with a coupling hole at the middle portion of the rear side, and the locking arm is detachably coupled to the coupling hole. Preferably, the 忒 设 arm arm is provided with a coupling rod, a connecting rod and a 桴 桴, wherein the coupling rod is combined with the switching shank coupling hole, and the connecting rod and the coupling rod are different from the connecting handle One end of the combination, and the card set 201236825 Fen and the 5 Hai connecting rod to meet people, and the gentleman & ^ ° eighty of the card arm of the card hole hole on the ^ ^ set the rod different from the connection On the end of the rod.

The reversing valve 2〇, the valve seat 22卩卩a 99' A Α Μ 22 holes 221 and the reverse air passage 422 enter the cylinder group 42 to make the rotor 4+ 浐妯 浐妯 卞 ~ d counterclockwise red rotation with respect to the rolling cylinder group 42, so that the pneumatic work can be retracted. /, U for the nut or bolt loosening by the above technical means, the original "moving tool into the I direction switching clothes Mainly through the switching handle 1 〇盥 拖 θ U U U U U U U U U U U U U U ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The cylinder group 42 generates clockwise or reverse time M & , , ^ stylus rotation, accurate forward rotation of the cylinder group 42, μ, 1 time extension of the rolling pass 422, that is, Τ transmission switching The pneumatic H1 type 髟, PU counterpart; the nut or bolt produces a lock or U operation, and only requires the body 41 when assembling. The money valve 20 is disposed in the shell 411 and located in the shell 411 After the cylinder group is cut and dragged, η ^ is lower, and then the clamping arm η, 11 Α of the switching handle 10 is clamped, and then the work is carried out. The assembly of the assembly, and then the m ^ ilS capture - can be easily switched, the dry operation is easy, the assembly is easy, and the cost is reduced. The pneumatic w ^ u tool has the air intake direction switching. The summer has 0 201236825 The above is only the invention. The preferred embodiments are not to be construed as limiting the scope of the present invention, and any one of ordinary skill in the art may be modified or modified without departing from the scope of the invention. Modifications of the equivalent embodiments, and without departing from the technical scope of the present invention, are still within the scope of the technical solutions of the present invention.
