PNEUMATIC NAILING GUN WITH SAFETY DEVICE Russian patent published in 2022 - IPC B25C1/04 

FIELD: pneumatic nail guns.

SUBSTANCE: invention relates to a pneumatic nail gun. The gun contains a working piston (10) connected to a driving hammer (12) for driving the fastener and loaded with compressed air when driving the driving process, a trigger mechanism (26) and a contact sensor (28), the joint actuation of which initiates the driving process, safety a device having a control volume (72) and designed to automatically take safety measures when the threshold pressure is exceeded or lowered in the control volume (72), moreover, the control volume through the throttle has the ability to pressurize or bleed air from it so that the delay time, after which the threshold pressure is exceeded or lowered, is set by the volume of the control volume (72) and the flow area of ​​the throttle, while the control volume (72) has a volume in the range from 0.5 ml to 20 ml, and the throttle has a drilling (54) with a diameter in the range from 30 mcm to 95 mcm.

EFFECT: creating a pneumatic nail gun with a compact design and a simple, strong and reliable safety mechanism.
