CPC classification number: B24B23/022 , B24B49/10 , B25F5/026
Abstract: A tool includes a prime mover, switch, operation member for the switch, first accessory, second accessory, third intermediate member moved in conjunction with displacement of the operation member, first intermediate member configured to be displaced from a first blocking position of blocking a displacement route of the third intermediate member to a first non-blocking position of not blocking the displacement route by attachment of the first accessory, and second intermediate member configured to be displaced from a second blocking position of blocking the displacement route to a second non-blocking position of not blocking the displacement route by attachment of the second accessory. Only when the first intermediate member is located at the first non-blocking position and the second intermediate member is located at the second non-blocking position, the third intermediate member is permitted to be displaced so that the operation member is permitted to be displaced to the ON position.

IPC: B24B23/02
Abstract: A tool includes a first accessory, at least two first attachment portions for detachably and selectively attaching the first accessory, and a single first intermediate member provided in common for the at least two first attachment portions. The first intermediate member includes at least one pressed portion configured to, when the first accessory is attached to one first attachment portion arbitrarily selected from the at least two first attachment portions, be directly or indirectly pressed by the first accessory. The first intermediate member is configured to be displaced when the at least one pressed portion is pressed. The tool further includes a single first sensor configured to detect that the first intermediate member is displaced.

Abstract: An electric tool includes a motor, a first intermediate member configured to be displaced when a first accessory is attached to a first attachment portion, a second intermediate member configured to be displaced when a second accessory is attached to a second attachment portion, and a first interlock member. The first interlock member mechanically moves in conjunction with the respective displacements of the first intermediate member and the second intermediate member. The first interlock member is displaced in the same direction between when the first accessory is attached and when the second accessory is attached, and is cumulatively displaced when the first accessory and the second accessory are attached. The electric tool is configured in such a manner that power supply to the motor is permitted only in a state that the first interlock member is cumulatively displaced.

Abstract: A power tool includes a motor configured to provide driving force to a tool accessory, a braking mechanism disposed on a driving-force-transmission path from the motor to the tool accessory and configured to put a brake on driving of the tool accessory, at least one attachment portion configured such that an accessory is removably attachable thereto, and a restricting member configured to be directly or indirectly pressed and displaced by the accessory when the accessory is attached to any one of the at least one attachment portion. In a state in which the accessory is not attached to any of the at least one attachment portion, the restricting member is located at a preventive position at which between-members abutment prohibits releasing of a braked state effected by the braking mechanism.
