Description

Single-shot or burst-firing nailer trigger

technical field

The utility model relates to a nailing gun trigger, in particular to a nailing gun trigger with adjustable single-shot or continuous firing.

Background technique

Please refer to China Taiwan Patent Application No. 92215992 for an improved structure patent for a nail gun trigger, which includes a trigger 40 , a rotating block 50 , a pressing piece 60 and a rotating part 70 . The trigger 40 is provided with a housing portion 41, and one end of the trigger 40 is provided with a perforation 42, the eccentric rotating block 50 is arranged in the perforating hole 42, and the position of the eccentric axis of the rotating block 50 is set There are internal threads 51, the pressing piece 60 is set in the accommodating portion 41, and the pressing piece 60 has a height difference, the rotating portion 70 is provided with a toggle block 71, and a screw The fastener 72 , the screw 73 is matched with the internal thread 51 of the rotating block 50 . When the toggle block 71 of the rotating part 70 is pulled to drive the trigger 40 and the pressing piece 60 to move forward, the high part 61 of the pressing piece 60 can be made to contact the touch switch 80 to generate a click action. And when the toggle block 71 of the turning part 70 is driven to move the trigger 40 and the pressing piece 60 backward, the lower part 62 of the pressing piece 60 can be made to contact the touch switch 80 to generate bursts of action.

The existing structure still has many disadvantages in practice, because when turning the toggle block 50, it is necessary to make the turn block 50 drive the trigger 40 and the pressing piece 60 to face forward or backward. Generate single-click or burst actions. If the toggle block 50 is rotated at other positions, the eccentric turn block 50 will drive the trigger 40 and the pressure piece 60 to move upward or downward, and if the trigger 40 is pressed at this time, it is easy to cause improper There is a safety hazard due to the action of nailing.

In addition, the rotating block 50 and the through hole 42 of the trigger 40 are in a circular pivot fit, and under the vibrations generated by multiple staples, it is easy to make the rotating block 50 and the trigger 40 generates relative rotation, causing the displacement between the pressing piece 60 and the touch switch 80, and incorrect nailing action occurs, which is quite impractical.

In addition, the rotating part 70 and the toggle block 71 are arranged on the outside of the trigger 40, so it is easy to change its position due to unintentional touch, and it will also cause incorrect nailing action. This kind of design that does not conform to industrial utilization is very impractical, so there is a need for improvement.
