DRIVING FASTENERS TOOL Russian patent published in 2022 - IPC B25C1/06 

FIELD: driving fasteners tool.

SUBSTANCE: invention relates to a tool for driving fasteners. The tool contains an energy storage mechanism (2), containing a cylinder (2-2) and a piston (2-1) in the housing (1), a clogging means (4), moreover, the piston (2-1) is connected to the clogging means (4), made with the possibility of passing into the nozzle (3) of the tool, the handle (5) with a battery pack located on one side of the cylinder (2-2), the drum (6) for nails located on one side of the nozzle (3) of the tool, and the lifting mechanism (7), located between the handle (5) and the drum (6) for nails, while the lifting mechanism (7) contains a driving means (4) having engagement teeth distributed at intervals along the length of the driving means, and a drive wheel (9) having engagement cylinders , distributed at intervals over a predetermined length, and the drive wheel is in gear connection with an electric motor (8), wherein the battery pack is configured to supply power to the electric motor (8). Moreover, the drive wheel (9) is equipped with gear shift fingers (9-3), which are made radially extending from opposite sides of the drive wheel (9) to a predetermined length, while the side surface of the driving means (4), located opposite the engagement teeth, is equipped with a retractable convex pin (4-1), made with the possibility of engagement with the fingers (9-3) of gear shifting, wherein the gearshift fingers (9-3) are made with the possibility, before the engagement cylinder enters the lifting engagement with the engagement teeth, to move to the engagement position and shift the gear in front of the retractable convex pin (4-1), moreover, the engagement cylinder is configured to lift the engagement with engagement teeth, and the shift fingers (9-3) are made with the possibility of transition to displace the retractable convex pin (4-1) to ensure that the engagement teeth are placed in the engagement position with the engagement cylinder.

EFFECT: providing a tool having a simple structure and effectively preventing interference between the engagement of the drive wheel and the engagement of the driving means at the time of re-lifting.
