A pneumatic tool includes a housing that contains an installation tunnel, an air supplying channel and first and second air inlets, a control valve installed in the installation tunnel for shifting among first, second and third positions; a controller that is mounted on the control valve and has two paddles; a pushing rod that passes through the controller and the control valve; and a trigger that is attached to the pushing rod. The pneumatic tool provides the controller for a user to selectively operate with his/her left hand or right hand to perform forward/reverse switching and speed adjustment.

1. A pneumatic tool using a single controller for both forward/reverse switching and speed adjustment, the pneumatic tool comprising: a housing, having an installation tunnel, an air supplying channel communicated with the installation tunnel, a first air inlet, and a second air inlet;a control valve, being such installed in the installation tunnel that the control valve is allowed to shift among a first position, a second position and a third position, wherein the control valve has an air incoming channel communicated with the air supplying channel, and an air supplying hole communicated with the air incoming channel, and the air supplying hole has an opening facing the housing;the controller, having a main body deposited in the control valve, and two paddles extending outward from two opposite sides of the main body, respectively, wherein the two paddles are exposed outside the housing for a user to operate one said paddle in order to rotate the controller and the control valve;a pushing rod, such passing through the controller and the control valve that the pushing rod is allowed to move along an imaginary axis, wherein the pushing rod has an inner end located in the air supplying channel, and an outer end opposite to the inner end; anda trigger, being deposited at the outer end of the pushing rod,wherein, the air supplying hole is communicated with the first air inlet when the control valve is at the first position, and is communicated with the second air inlet when the control valve is at the second position and the third position, and corresponding areas between the opening of the air supplying hole and the second air inlet formed when the control valve is at the second position and at the third position are different; andwherein the control valve has a rear section, a middle section, and a front section, in which the air supplying hole is located in the rear section, and the controller is located in the front section, and the middle section has an exhausting trough, while the housing further comprises an exhausting channel and an air outlet that are communicated with the exhausting trough. 2. The pneumatic tool of claim 1, wherein the housing further comprises a groove that is parallel to the imaginary axis, and the trigger has a main body for the user to operate and a bump such raised from the main body that the bump is received in the grooved of the housing. 3. The pneumatic tool of claim 1, wherein the housing further comprises a guide that is parallel to the imaginary axis, and the trigger has a guiding groove that matches the guide. 4. The pneumatic tool of claim 1, wherein the installation tunnel of the housing has an inner wall and a first positioning recess, a second positioning recess and a third positioning recess that are depressed from the inner wall, and the controller has a socket that receives therein a spring member and a ball propping up by the spring member, in which the ball is retained by the first positioning recess, the second positioning recess, and the third positioning recess, respectively, when the control valve is at the first position, the second position, and the third position. 5. The pneumatic tool of claim 4, wherein the control valve has an engaging notch, and the controller has an outer periphery, an inner periphery, and an engaging block that is raised form the inner periphery and receiving in the engaging notch, in which the socket is depressed form the outer periphery and extends to the engaging block. 6. The pneumatic tool of claim 1, wherein the control valve has an outer surface on which the opening of the air supplying hole is located, and the exhausting trough of the middle section is depressed from the outer surface. 7. The pneumatic tool of claim 1, wherein a seal ring is provided between the pushing rod and the control valve, and the air supplying hole of the control valve is located between the seal ring and the air supplying channel. 8. The pneumatic tool of claim 1, wherein the housing further comprises an exhausting channel and an air outlet that are communicated with the installation tunnel, and the control valve has an outer surface and an exhausting trough that is depressed form the outer surface and is communicated with the exhausting channel and the air outlet, while the outer surface is further provide with a seal ring, so that the seal ring is located between the exhausting trough and the controller.
