Abstract: A reciprocating cutting tool reduces deteriorating movement of an operating drum due to entry of chips between the operating drum and a housing. A reciprocating cutting tool includes a motor, a slider being rod-like and extending in a front-rear direction, a reciprocation converter that converts rotation of the motor to reciprocation in the front-rear direction and transmits the reciprocation to the slider, a power transmission housing accommodating the reciprocation converter, a tip tool holder at a front end of the slider to detachably receive a tip tool, and an operating drum operable to attach or detach the tip tool with the tip tool holder through rotation. The operating drum is rotatably held on the power transmission housing with one or more ring members.

Abstract: A jigsaw may include a housing, a control member, a shoe member and a keel. The housing contains a motor and include a handle. The control member is moveable relative to the housing between at least a first position that implements a curve-cutting mode and a second position that implements a straight-cutting mode. The shoe member is connected to the housing and includes a bottom surface facing away from the housing. The keel is operable in a deployed configuration in which the keel protrudes through the bottom surface of the shoe member and a stowed configuration in which the keel does not protrude through the bottom surface of the shoe member. Relative motion between the shoe and the keel allows the keel to be in the deployed configuration when the control member is in the second position and the stowed configuration when the control member is in the first position.

Abstract: The present invention provides a technique for achieving weight reduction of the counter weight while reducing vibration in a reciprocating power tool. A tool bit performs a predetermined operation by reciprocating. A slider reciprocates to drive the tool bit. A motion converting mechanism converts a rotating output of the motor into a reciprocating movement of the slider. A counter weight reciprocates in a direction opposite to the reciprocating direction of the slider to reduce vibration caused by the reciprocating movement of the slider. A component part includes component of motion in a direction parallel to the reciprocating movement of the slider to cooperate with the counter weight in reducing vibration caused within the power tool. Thus, the weight of the counter weight can be decreased.

Abstract: A support arrangement for a reciprocating tool comprises a first locking surface configured to engage a second locking surface in a locking engagement. The first locking surface is secured to the reciprocating tool. The second locking surface is provided on a support foot assembly. A shaft extends between the first locking surface and the second locking surface. The shaft defines a shaft axis that is oriented substantially orthogonal to the tool axis. An adjustment mechanism is positioned on the shaft. The adjustment mechanism is configured to move upon the shaft and clamp the first locking surface and the second locking surface together. In at least one embodiment, a ratchet arrangement is provided in the adjustment mechanism. The ratchet arrangement limits the extent that the adjustment mechanism may be tightened to clamp the first locking surface to the second locking surface.
