Abstract

A driving tool includes an electric motor, a battery mount that receives a battery for powering the electric motor, a flywheel that rotates by the electric motor, a magazine that loads a connected fastener rolled in a coil and including a plurality of fasteners temporarily connected in parallel, an impact driver that advances through a driving path with rotational power of the flywheel to drive the fasteners, and a feed mechanism that feeds the connected fastener by a pitch from the magazine toward the driving path.

First claim

What is claimed is:

1. A driving tool, comprising:
an electric motor;
a battery mount configured to receive a battery for powering the electric motor;
a flywheel configured to be rotated by the electric motor;
a magazine configured to contain a connected fastener rolled in a coil, the connected fastener including a plurality of fasteners connected in parallel;
an impact driver configured to advance through a driving path by rotational power of the flywheel to drive the fasteners of the plurality of fasteners;
a feed mechanism configured to feed the plurality of fasteners from the magazine to the driving path; and
an electromagnetic actuator that is configured to be a power source for the feed mechanism, wherein
the feed mechanism includes a feed tab that is configured to engage the plurality of fasteners individually and is reciprocally movable in a feed direction of the connected fastener and a reverse direction opposite the feed direction,
the feed mechanism includes a feed rod, and
the electromagnetic actuator and the feed rod are configured such that:
the electromagnetic actuator is turned off to advance the feed rod in the feed direction, and
the electromagnetic actuator is turned on to retract the feed rod in the reverse direction.

2. The driving tool according to claim 1 , wherein
the feed mechanism transmits power of the electromagnetic actuator to the feed tab using fluid pressure.

3. The driving tool according to claim 1 , wherein
the electromagnetic actuator is configured to be powered by the battery.

4. The driving tool according to claim 2 , wherein
the electromagnetic actuator is configured to be powered by the battery.

5. The driving tool according to claim 4 , wherein the feed mechanism is configured to transmit power of the electromagnetic actuator to the feed tab using oil pressure.

6. The driving tool according to claim 2 , wherein A driving tool, comprising:
an electric motor;
a battery mount configured to receive a battery for powering the electric motor;
a flywheel configured to be rotated by the electric motor;
a magazine configured to contain a connected fastener rolled in a coil, the connected fastener including a plurality of fasteners connected in parallel;
an impact driver configured to advance through a driving path by rotational power of the flywheel to drive the fasteners of the plurality of fasteners;
a feed mechanism configured to feed the plurality of fasteners from the magazine to the driving path; and
an electromagnetic actuator that is configured to be a power source for the feed mechanism, wherein
the feed mechanism includes a feed tab that is configured to engage the plurality of fasteners individually and is reciprocally movable in a feed direction of the connected fastener and a reverse direction opposite the feed direction, and
the feed mechanism is configured to transmit power of the electromagnetic actuator to the feed tab using oil pressure.
