Abstract
A driving tool includes a head-guide surface and a pair of leg-guide grooves, both are formed in a driving passage extending in a driving direction. The head-guide surface slidably guides a head of a U-shaped driving member. Each of the pair of leg-guide grooves is recessed from the head-guide surface toward a side of a first end surface of a tool main body. Legs of the driving member enter the leg-guide grooves. The driving member is driven in an inclined posture in which the legs enter the leg-guide groove, thereby avoiding a slipping off posture in which a driver is deviated from the driving member owing to a reaction force occurred when the driving member is driven by the driver.
Claims20
A driving tool comprising:
- a tool main body including a first end surface;
- a driving passage extending along the first end surface of the tool main body in a driving direction into which a U-shaped driving member having a head and two legs is supplied from a direction opposite to the first end surface;
- a driver configured to move along the driving passage for driving the driving member;
- a head-guide surface formed in the driving passage, the head-guide surface slidably guiding the head of the driving member;
- and
- a pair of leg-guide grooves, each of the pair of leg-guide grooves being configured to be recessed from the head-guide surface toward a side of the first end surface of the tool main body and extend parallel to the driving direction along an entirety of the driving passage such that the two legs of the driving member enter the pair of leg-guide grooves so as to be non-parallel to the driving direction.

A driving tool comprising:
- a tool main body including a first end surface and a base portion;
- a driver nose including a driver guide configured to connect a front surface of the base portion, the driver guide overlapping with the front surface of the base portion;
- a driving passage extending in a driving direction at which a driving member is provided in a direction opposite to the first end surface, the driving member further comprising a head and two legs;
- a pusher having a recessed portion configured to face the driving passage for preventing the head of the driving member from contacting the pusher;
- a driver configured to move along the driving passage for driving the driving member, the driver further comprising a plurality of engaged portions formed on a right side of the driver, each of the plurality of engaged portions being arranged at a specified interval in a longitudinal direction of the driver;
- a lifter arranged on a right side of the driver, the lifter comprises a plurality of engaging pins, each of the plurality of engaging pins is arranged at a specified interval along an outer peripheral portion of the lifter, the plurality of engaging pins covering three quarters of a circumference of the lifter;
- a head-guide surface formed in the driving passage, the head-guide surface slidably guiding the head of the driving member;
- a pair of leg-guide grooves, each of the pair of leg-guide grooves being configured to recess from the head-guide surface toward a side of the first end surface and extend parallel to the driving direction along an entirety of the driving passage, the two legs of the driving member entering the pair of leg-guide grooves so as to be non-parallel to the driving direction;
- and
- a driver-guide groove formed in the driving passage and allocated between the pair of leg-guide grooves.
