Abstract: A power tool includes an inner housing (50) at least partially housed within and spaced from an outer housing (30). The inner housing supports a tool (102, 302), such as a pair of shear blades, and houses a motor (80) that drives the tool. The outer housing includes a grip (14, 18) to be grasped by a user. At least one vibration insulator (71-75) can be disposed between the inner housing and the outer housing and in a manner such that the vibration insulator(s) is(are) protected by the outer housing. An intake opening (60a, 60b) and exhaust opening (64a, 64b) can be formed in the inner housing and can be shielded by respective portions of an inner surface of the outer housing.

Abstract: An operation switch device for use with a lawnmower includes a switch and a first operation member operably movable between an "ON" position and an "OFF" position. A second operation member is mounted on the first operation and is positionable in a first position where the switch is turned on and a second position where the switch is held off when the first operation member is in the "ON" position and the "OFF" position, respectively. A restraining member in a restraining position is operable to prevent the second operation member from moving from the second position to the first position. The restraining member in a releasing position is operable to permit the second operation member to move from the second position to the first position.
