The switch mechanism for the reversible control valve of the pneumatic tool focuses on the switchover bar because of the users' right handed and left-handed issues. The primary feature is to make the switchover bar of the reversible control valve and the speed-adjusting valve to roll in the axial direction, and use the combination of the elastic component to make the combination and position section of the connecting section to position with the valve bar positioning section of the reversible control valve. When force of the connecting section of the switchover bar is pulled toward external trigger, it can release the combination and position section and the toggle switch of the switchover bar can achieve switching. When the toggle switch is adjusted, the repositioning may be restored by using the combination and position section and valve bar positioning section without having to take the parts apart.

We claim: 1. An apparatus comprising: a pneumatic tool having a reversible control valve, said pneumatic tool having an air inlet channel, said reversible control valve having a center and an outside and an inside and an external end, said center having a through slit formed therein, said reversible control valve being turnably positioned on said air inlet channel, said reversible control valve having an air hole therein, said reversible control valve having a handle with a protruding tube on an external side thereof, said reversible control valve having a valve bar positioning section positioned thereon; a switchover bar having a connecting section and a toggle switch, said connecting section positioned on said outside of said reversible control valve, said connecting section having a combination and position section positioned with said valve bar positioning section on said external end of said reversible control valve, said toggle switch extending toward one side of said connecting section; a trigger bar having stick rolls extending through said through slit of said reversible control valve, said trigger bar having a limit block positioned therein so as to block said inside of said reversible control valve such that said trigger cannot roll outwardly, said trigger bar having an external side protruding outwardly so as to form a trigger connector; a trigger connected to said trigger connector; and an elastic component positioned in an area of said switchover bar so as to urge said switchover bar to a position. 2. The apparatus of claim 1, said valve bar positioning section and said combination and position section being a concave slot and a protruding block. 3. The apparatus of claim 2, further comprising: a speed-adjusting valve attached to said through slit of said reversible control valve, said speed-adjusting valve turnable and rollable in an axial direction, said speed-adjusting valve having a control wheel on an external end thereof urging against the external side of said connecting section of said switchover bar. 4. An apparatus comprising: a pneumatic tool having a handle with an air inlet channel, said air inlet channel having a horizontal slot thereon; a reversible control valve formed of a hollow cylinder with a through slit in a center thereof, said reversible control valve positioned in said horizontal slot, said reversible control valve having an axle positionable by bolt bolted horizontally to said handle, said reversible control valve having an air hole in an inner wall thereof, said reversible control valve being a protruding tube at an external end thereof, said protruding tube extending to an external side of said handle, said reversible control valve having a valve bar positioning section positioned on an external side thereof a switchover bar having a connecting section and a toggle switch, said connecting section being a round cylinder connected to said protruding tube, said connecting section having a combination and position section on an inside thereof, said combination and position section being positioned with said valve bar on an outside of said reversible control valve, said toggle switch facing one side of said handle, said toggle switch being switchable so as to turn with said reversible control valve so as to change a relative angle of said air hole; a speed-adjusting valve of a hollow cylindrical shape, said speed-adjusting valve positioned in said through slit so as to turn and roll in an axial direction, said speed-adjusting valve having a control wheel on an external side thereof, said control wheel having an expanded outer diameter, said control wheel positioned on an outside of said connecting section of said switchover bar so as to prevent said speed-adjusting valve from rolling inwardly and to limit a movement of said switchover bar, said speed-adjusting valve having a through hole in a center thereof, said through hole having a section of expanded diameter on an outside thereof, said section of expanded diameter defining a shoulder; a trigger bar having stick rolls extending through said through hole of said speed-adjusting valve, said trigger bar having a limit block positioned therein so as to block said through slit of said reversible control valve so as to prevent said trigger bar from rolling outwardly, said trigger bar having an external side protruding outwardly from an outside of said handle so as to form a trigger connector; a trigger having a button-shaped body, said trigger having an inside connected to an external end of said trigger bar, said trigger and said control wheel having a space therebetween; and an elastic component positioned between said shoulder and an internal surface of said trigger so as to urge said trigger outwardly, said elastic component pushing said speed-adjusting valve inwardly such that said control wheel pushes against said connecting section, said combination and position section being positioned with the valve bar positioning section. 5. The apparatus of claim 4, said valve bar positioning section having a pair of concave slots positioned on an opposite sides of said protruding tube, said combination and position section being protruding blocks positioned on opposite sides of said connecting section. 6. The apparatus of claim 4, said limit block being an expanded round ball. 7. The apparatus of claim 4, said elastic component being a spiral spring. 8. An apparatus comprising: a pneumatic tool having an air inlet channel; a reversible control valve positioned on said air inlet channel, said reversible control valve having an axle, said reversible control valve having a through slit positioned in a center thereof, said reversible control valve having an air hole positioned therein, said reversible control valve having a handle extending therefrom, said handle having a protruding tube positioned on an external side thereof, said external side having a valve bar positioning section placed thereon; a switchover bar having a connecting section and a toggle switch, said connecting section positioned on an outside of said reversible control valve, said connecting section having a combination and position section positioned with said valve bar positioning section on an external end of said reversible control valve, said toggle switch extending toward one side of said connecting section; a positioning shaft placed in said through slit of said reversible control valve so as to limit a movement of said switchover bar; and an elastic component positioned in an area of said switchover bar so as to urge against said switchover bar. 9. The apparatus of claim 8, said valve bar positioning section and said combination and position section being a concave slot and a protruding block. 10. The apparatus of claim 8, further comprising: a speed-adjusting valve positioned in said through slit, said speed-adjusting valve being turnable and rollable in an axial direction, said speed-adjusting valve having a control wheel on an external side thereof, said control wheel pushing against an outside of said connecting section of said switchover bar so as to limit a movement of said speed-adjusting valve and said switchover valve. 11.
