Description

本発明は、携帯用切断機などの電動工具に関する。 The present invention relates to a power tool such as a portable cutting machine.

上記課題を解決するために本発明は、被加工材を切断する切断刃と、該切断刃を回転駆動するためのモータを収納するハウジングと、前記ハウジングに固定され前記切断刃を覆うソーカバーと、前記モータの回転駆動を制御するトリガを有したハンドルと、を有する本体部と、前記ハウジングに接続され前記被加工材上を摺動し、前記切断刃が突出する開口部を有するベース部と、を備えた携帯用切断機において、前記本体部に設けられ、前記モータの駆動を可能にする位置と、前記モータの駆動を不可能にする位置とで移動可能な移動規制部材を備えた携帯用切断機を提供する。
または、モータと、前記モータの回転駆動を制御するトリガを有したハンドルと、を有する本体部と、を備えた電動工具において、略Ｕ字形状をし、フック端部、中間部、回動軸を有し、前記本体部に前記回動軸が回動可能に支持されたフック部材を設け、前記フック部材の回動位置に応じて、前記トリガの操作にかかわらず前記モータの駆動を不可能にする電動工具を提供する。 In order to solve the above problems, the present invention provides a cutting blade for cutting a workpiece, a housing for storing a motor for rotationally driving the cutting blade, a saw cover fixed to the housing and covering the cutting blade, A handle having a trigger for controlling the rotational drive of the motor; and a base having an opening that is connected to the housing and slides on the workpiece and from which the cutting blade protrudes. A portable cutting machine provided with a movement restricting member which is provided on the main body and is movable between a position where the motor can be driven and a position where the motor cannot be driven. to provide a cutting machine.
Alternatively, in an electric tool including a motor and a main body having a handle having a trigger for controlling rotation driving of the motor, the electric tool has a substantially U shape, and has a hook end, an intermediate portion, and a rotation shaft. A hook member rotatably supported by the rotation shaft is provided on the main body, and the motor cannot be driven regardless of the operation of the trigger according to the rotation position of the hook member. A power tool is provided.

なお、前記移動規制部材は、フック部材であることが好ましい。 The movement restricting member is preferably a hook member.

なお、前記フック部材は、切断方向後方であって前記本体部の前記モータ側の側面にフック回動軸を有し、該フック回動軸を中心に回動可能で、且つ前記フック回動軸方向に摺動可能に支持されていることが好ましい。 The hook member has a hook rotation shaft on a side surface on the motor side of the main body portion in the cutting direction, is rotatable about the hook rotation shaft, and the hook rotation shaft. It is preferably supported so as to be slidable in the direction.

なお、前記本体部はフック当接部を有し、前記フック部材が前記フック当接部と非当接状態のとき、前記モータの駆動を可能にし、前記フック部材が前記フック当接部と当接状態のとき、前記モータの駆動を不可能にすることが好ましい。 The main body portion has a hook contact portion, and when the hook member is not in contact with the hook contact portion, the motor can be driven, and the hook member is in contact with the hook contact portion. In the contact state, it is preferable that the motor cannot be driven.

なお、前記本体部内には前記移動規制部材に接続され前記トリガの操作を規制する規制部を有し、前記移動規制部材の回動動作に伴って前記規制部は規制回動軸を中心に回動されることにより、前記トリガ操作が規制され、前記モータの駆動を不可能にすることが好ましい。

The main body has a restricting portion that is connected to the movement restricting member and restricts the operation of the trigger, and the restricting portion rotates around a restricting rotation axis as the movement restricting member rotates. By being moved, it is preferable that the trigger operation is restricted and the motor cannot be driven.
