There is provided a driving tool for driving a fastener to a fastening target object including: a contact arm capable of moving in a first direction by being brought into contact with and pressed against the fastening target object; a driving portion configured to start a driving operation of the fastener on condition that the contact arm moves by a predetermined amount in the first direction; and a restricting portion configured to restrict the driving operation performed by the driving portion when an inertial force is generated in the first direction.

Driving tool

A pneumatic tool includes a trigger configured to perform a first operation of operating a drive part, a contact member configured to perform a second operation of operating the drive part, a timer configured to measure the time during which the drive part can be operated by the second operation of the contact member and to switch the operation mode of the drive part after the time has elapsed, and a timer switch configured to control the operation of the timer. The first operation of the trigger is transmitted to the timer switch using a transmitting member.

Pneumatic tool

A pneumatic tool includes a drive part configured to be driven by compressed air, a control valve configured to switch the presence or absence of operation of the drive part, and a timer part configured to switch the presence or absence of operation of the control valve after a lapse of a predetermined time. The timer part includes a timer piston configured to move in one direction, a timer piston cylinder configured to support the timer piston such that the timer piston can slide, and an on-off valve part configured to switch the presence or absence of operation of the control valve in conjunction with the timer piston. The on-off valve part includes a shaft portion configured to move in conjunction with the timer piston, and compressed air flowing into the on-off valve part presses the shaft portion in the one direction.

A pneumatic tool includes a drive part configured to be driven by compressed air, a control valve configured to switch the presence or absence of operation of the drive part, an on-off valve part configured to switch the presence or absence of operation of the control valve, and a timer part configured to control the operation of the on-off valve part and switch the presence or absence of operation of the control valve after a lapse of a predetermined time. The timer part comprises a timer piston configured to move in one direction and perform timekeeping, and a timer piston housing configured to support a shaft of the timer piston. The timer piston housing is provided with a groove on a guide surface of the shaft of the timer piston, the groove being configured to expand a flow path formed between the shaft and the guide surface.

A pneumatic tool includes a drive part configured to be driven by compressed air, a control valve configured to switch the presence or absence of operation of the drive part, an on-off valve part configured to switch the presence or absence of operation of the control valve, and a timer part configured to control the operation of the on-off valve part and switch the presence or absence of operation of the control valve after a lapse of a predetermined time. The timer part comprises a timer piston configured to move in one direction, and a timer piston cylinder configured to support the timer piston. The pneumatic tool comprises a throttle part configured to throttle the flow rate of air flowing into or flowing out from the timer piston cylinder, and an adjustment part configured to adjust an operating time of the timer piston.

A fastener driving tool includes a nose portion, a supply passage and a fastener supply mechanism. The nose portion includes an injection passage for injecting a fastener. The supply passage is connected to the injection passage. The fastener supply mechanism feeds connected fasteners to the injection passage. The fastener supply mechanism includes a feed member which advances and retreats in a feed direction and which oscillates in a direction to retreat from the supply passage. The feed member includes a feed tooth which feeds the fastener to the injecting passage by engaging with a rear portion of the fastener and an auxiliary tooth which is disposed on a foot side of the fastener to prevent the fastener from deviating from the injection passage. When the feed tooth of the feed member projects into the supply passage, the auxiliary tooth projects into the supply passage longer than the feed tooth.

Fastener driving tool

A fastener driving tool injects a fastener from an injection passage formed in a leading end of a tool main body. The injection passage includes therein a guide portion formed along a driving direction of the fastener for guiding the fastener. The guide portion is formed by providing contours having mutually different distances from a center of the injection passage in a cross-section of the injection passage.
