Abstract
A reciprocating tool includes a housing, a spindle having an end configured to receive a saw blade, and a blade clamp mechanism supported on the spindle and configured to attach the saw blade to the spindle. The blade clamp mechanism includes a locking member movable relative to the spindle between a locked position and an unlocked position. The blade clamp mechanism also includes an actuating member that is rotatable relative to the spindle between an engaged position and a released position. The actuating member defines a gripping surface with ridges and includes a first tab and a second tab, each of the first tab and the second tab protruding radially from the outer gripping surface.
Claims14
A reciprocating tool comprising:
- a housing;
- a spindle mounted for reciprocating movement within the housing and having an end configured to receive a saw blade;
- a blade clamp mechanism supported on the spindle and configured to attach the saw blade to the spindle, the blade clamp mechanism including
- a lock movable relative to the spindle between a locked position that locks the saw blade to the spindle and an unlocked position that releases the saw blade;
- and
- an actuator supported adjacent the end of the spindle and rotatable relative to the spindle between an engaged position corresponding to the locked position of the lock, and a released position corresponding to the unlocked position of the lock, the actuator defining an outer gripping surface with ridges and including a first tab and a second tab, each of the first tab and the second tab protruding radially from the outer gripping surface;
- and
- a shoe assembly coupled to the housing and including a first bar and a second bar, each of the first bar and the second bar having a flat upper surface cooperatively defining an upper shoe plane and a flat lower surface cooperatively defining a lower shoe plane;
- wherein the first tab includes a first planar lateral surface, a second planar lateral surface located opposite the first planar lateral surface, and a tip end surface spaced from the gripping surface, the tip end surface extending an entire distance between the first planar lateral surface and the second planar lateral surface;
- wherein when the actuator is in the engaged position,
- the upper shoe plane intersects the first planar lateral surface and the tip end surface of the first tab but does not intersect the second planar lateral surface of the first tab,
- at least a portion of the first tab protrudes beyond the upper shoe plane, and
- at least a portion of the second tab protrudes beyond the lower shoe plane;
- and
- wherein when the actuator is in the released position,
- the first tab is positioned between the upper shoe plane and the lower shoe plane, and
- the second tab is positioned between the upper shoe plane and the lower shoe plane.
