れる。With the above construction, when the trigger lever 4 is rotated counterclockwise in FIG.
Is held in the first position, the valve stem 12 of the starting valve can be pushed and actuated by operating the trigger lever 4. When the fastener 7 in the magazine 3 is consumed little by little, the pusher 10 also moves forward by the amount consumed. When the remaining amount of the fastener 7 on the guide path 8 decreases in this way, the protrusion 16 of the pusher 10 engages with the piece 15b of the L-shaped lever 15 and rotates it as shown in FIG. When the remaining fasteners 7 become a few, the other piece 15a of the L-shaped lever 15
Engages with the lower end of the actuating member 14 and pushes it up
Move to the position. Therefore, even if an attempt is made to operate the trigger lever 4, its front end face engages with the upper end of the operating member 14 and cannot rotate, so that the operation is blocked.

よい。By the way, in the above example, the projecting portion 16 of the pusher 10 is engaged with the actuating member 14 via the L-shaped lever 15, so that the actuating member 14 is moved from the first position to the second position. However, the present invention is not limited to this, and the protrusion 16 of the pusher 10 may be directly engaged with the operating member 14. For example, as shown in FIG. 4, the front portion of the upper end of the protruding portion 16 of the pusher 10 is used as a slanted guide surface, and the number of fasteners 7 is reduced so that the protruding portion 16 of the pusher 10 moves forward to engage with the lower end of the operating member 14. The actuating member 14 that was in the first position when mated
The lower end of the guide 16 may be guided by the guide surface to move up to the second position as shown in FIG. 5, and contact the upper end of the protrusion 16.

することができる。When the number of fasteners in the magazine is reduced, the protrusion of the pusher is engaged with the actuating member to move the actuating member from the first position to the second position, thereby starting the nailing machine. The operation of the trigger lever can be locked to prevent damage to the driven material due to blank driving. Therefore, even a small nailing machine that cannot have a contact arm can be equipped with a mechanism for preventing blank driving.
