Power tool with operation assembly

A tool comprising:

• a prime mover;
• a switch for driving the prime mover;
• an operation member configured to be displaceable between an OFF position of bringing the switch into an OFF state and an ON position of bringing the switch into an ON state;
• a first accessory;
• a second accessory;
• a first attachment portion configured to allow the first accessory to be detachably attached thereto;
• a second attachment portion configured to allow the second accessory to be detachably attached thereto;
• a first intermediate member configured to be displaced by the attachment of the first accessory to the first attachment portion;
• a second intermediate member configured to be displaced by the attachment of the second accessory to the second attachment portion;
• and
• a third intermediate member configured to be displaced along a displacement route between an OFF corresponding position corresponding to the OFF position and an ON corresponding position corresponding to the ON position in conjunction with the displacement of the operation member,
• wherein the first intermediate member is located at a first blocking position of blocking the displacement route of the third intermediate member in a state that the first accessory is not attached to the first attachment portion, and is located at a first non-blocking position of not blocking the displacement route of the third intermediate member in a state that the first accessory is attached to the first attachment portion,
• the second intermediate member is located at a second blocking position of blocking the displacement route of the third intermediate member in a state that the second accessory is not attached to the second attachment portion, and is located at a second non-blocking position of not blocking the displacement route of the third intermediate member in a state that the second accessory is attached to the second attachment portion,
• 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 from the OFF corresponding position to the ON corresponding position so that the operation member is permitted to be displaced from the OFF position to the ON position,
• when at least the first intermediate member is located at the first blocking position or at least the second intermediate member is located at the second blocking position, the third intermediate member is prohibited from being displaced from the OFF corresponding position to the ON corresponding position by at least one of the first intermediate member in the first blocking position or the second intermediate member in the second blocking position so that the operation member is prohibited from being displaced from the OFF position to the ON position,
• the prime mover is an electric motor,
• the tool is a grinder including a tool accessory configured to be rotated by the electric motor,
• the first accessory is a side grip, and
• the second accessory is a cover that partially covers the tool accessory,
• the first attachment portion includes at least two side grip attachment portions for selectively attaching the side grip,
• the first intermediate member is a single member provided in common for the at least two side grip attachment portions, and
• the first intermediate member includes at least one pressed portion configured to, when the side grip is attached to one side grip attachment portion arbitrarily selected from the at least two side grip attachment portions, be directly or indirectly pressed by the side grip, and the first intermediate member is configured to be displaced when the at least one pressed portion is pressed.

• a second attachment portion configured to allow the second accessory to be detachably attached thereto;
• a first intermediate member configured to be displaced by the attachment of the first accessory to the first attachment portion;
• a second intermediate member configured to be displaced by the attachment of the second accessory to the second attachment portion;
• a third intermediate member configured to be displaced along a displacement route between an OFF corresponding position corresponding to the OFF position and an ON corresponding position corresponding to the ON position in conjunction with the displacement of the operation member;
• and
• a single holding member that holds the first intermediate member and the second intermediate member,
• wherein the first intermediate member is located at a first blocking position of blocking the displacement route of the third intermediate member in a state that the first accessory is not attached to the first attachment portion, and is located at a first non-blocking position of not blocking the displacement route of the third intermediate member in a state that the first accessory is attached to the first attachment portion,
• the second intermediate member is located at a second blocking position of blocking the displacement route of the third intermediate member in a state that the second accessory is not attached to the second attachment portion, and is located at a second non-blocking position of not blocking the displacement route of the third intermediate member in a state that the second accessory is attached to the second attachment portion,
• 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 from the OFF corresponding position to the ON corresponding position so that the operation member is permitted to be displaced from the OFF position to the ON position, and
• when at least the first intermediate member is located at the first blocking position or at least the second intermediate member is located at the second blocking position, the third intermediate member is prohibited from being displaced from the OFF corresponding position to the ON corresponding position by at least one of the first intermediate member in the first blocking position or the second intermediate member in the second blocking position so that the operation member is prohibited from being displaced from the OFF position to the ON position.
