Abstract

PROBLEM TO BE SOLVED: To return a trigger valve to the initial state by releasing the push-up operation of a push lever in single driving by releasing only the push-up operation of the push lever after single driving is ended, so that an arm plate never interferes therewith. SOLUTION: When the pulling operation of a trigger 3 is released in the state there the push-up operation of a push lever 4 is released in a single driving, the engagement of the protruding part 7a of an arm plate 7 with the lower end part of a plunger 2 is released, and the arm plate 7 is slid on the push lever 4 side by a spring 8 so that the interference of the arm plate is eliminated, and laid in the initial state. Since a trigger valve 1 is returned to the initial state even in single driving by releasing the push-up operation of the push lever 4, a striking mechanism is returned to the initial state at the same time when a body is separated from a material subjected to driving after the driving is end, and exhaust of compressed air which is a returning process is performed.

2. Description of the Related Art An example of a conventional driving machine is disclosed in JP-A-7-23.
There is a driving machine described in Japanese Patent No. 7148, which can switch between single shot and continuous firing by changing the operation sequence of a trigger and a push lever. This means that if the push lever is operated after the trigger is pulled, the striking will be repeated, and if the trigger is pulled after the push lever is operated, the striking will be single-shot. In some cases, the trigger valve was locked in the operating state.

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 7-2
In the driving machine disclosed in Japanese Patent No. 37148, the trigger valve is locked in the operating state at the time of a single shot. Therefore, in the case of the single shot, the hitting mechanism is in the driving state after the end of the driving. Therefore, at the same time when the operation of the trigger is released, the trigger valve returns to the initial state, and the striking mechanism also returns to the initial state, and the compressed air is exhausted, which is the return stroke of the striking mechanism. After the driving is completed, the main body may be moved to check the driving condition.However, if the trigger operation is released at this time, there is a disadvantage that the driving mechanism suddenly returns to the initial state and the compressed air is exhausted. Was.
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide a driving machine in which a trigger valve returns to an initial state by releasing a push-up operation of a push lever even in a single shot.

The trigger valve 1 is operated by pulling the trigger 3.
When the push-up operation of the push lever 4 is released after the operation is performed and the push lever 4 is released, the plunger 2 descends with the depression of the push lever 4 and the trigger valve 1 returns to the initial state. Returns to the state.
When the plunger 2 is lowered, the trigger arm 5 and the arm plate 7 rotate downward by the amount of the lowering of the plunger 2. At this time, the projection 7 a of the arm plate 7 and the lower end of the plunger 2 abut by the action of the spring 8. The arm plate 7 keeps sliding to the trigger 3 side. In this state, even if the push-up operation of the push lever 4 is performed again, the upper end of the push lever 4 does not come into contact with the arm plate 7 as shown in FIG. For this reason, the push lever 4
Even if the push-up operation is performed, the driving is not performed. Reference numeral 3a denotes an abutting surface provided on the trigger 3 which abuts against the bottom of the trigger arm 5. When the push-up operation of the push lever 4 is released and the plunger 2 is lowered, the trigger arm 5 pivots downward and the arm plate is rotated. 7
The projection 7a is provided to prevent the engagement between the lower end of the plunger 2 and the projection 7a from being released.

As described above, when the push-up operation of the push lever 4 is released after the single hit, the upper end of the push lever 4 does not come into contact with the arm plate 7, so that the push-up operation of the push lever 4 is released. As a result, the trigger valve 1 returns to the initial state. As described above, even in the case of a single shot, since the trigger valve 1 returns to the initial state by releasing the push-up operation of the push lever 4, the main body is separated from the material to be driven after the completion of the driving, and the striking mechanism is in the initial state. And the compressed air, which is the return stroke, is discharged.
