Patent Images
1. A pneumatic tool driving assembly comprising:
- a valve housing defining first and second chambers and a valve opening that is disposed between said first and second chambers for fluid communication between said first and second chambers;
a valve mechanism including a valve actuator that extends into said valve housing, and a valve member that is disposed in said valve housing for closing said valve opening and that is actuated by said valve actuator to uncover said valve opening; and
a trigger mechanism pivoted to an exterior of said valve housing so as to be pivotably pressible relative to said valve housing between a non-pressed position and a pressed position, said trigger mechanism driving said valve actuator to move to actuate said valve member when moving from the non-pressed position to the pressed position, said trigger mechanism including a detachable wrench that is spaced apart from said valve housing, and a pivot joint that is pivoted to said valve housing and that brings said wrench to pivot relative to said valve housing between the non-pressed position and the pressed position.

Abstract
A pneumatic tool driving assembly comprises: a valve housing defining first and second chambers and a valve opening; a valve mechanism including a valve actuator that extends into the valve housing, and a valve member that is disposed for closing the valve opening and that is actuated by the valve actuator to uncover the valve opening; and a trigger mechanism pivoted to an exterior of the valve housing so as to be pressible relative to the valve housing. The trigger mechanism includes a detachable wrench that is spaced apart from the valve housing, and a pivot joint that is pivoted to the valve housing and that brings the wrench to pivot relative to the valve housing.
