Power tool
First Claim
1. A power tool comprising:
- a base having a sliding surface slidable on a workpiece, another surface opposite to the sliding surface, and an opening provided through the base between the sliding surface and the another surface;
a main unit supported on a first side of the another surface and movable in a first direction substantially perpendicular to the sliding surface, the main unit including an electric motor; and
a cutter driven by the electric motor, the cutter being capable of protruding through the opening from the sliding surface when the main unit is moved to the base;
a bolt having a longitudinal axis and extending in the is first direction on the first side, the bolt having a first male thread portion and one end supported by the base, the bolt being rotatable about the longitudinal axis;
an engagement member related with the main unit and having a first female thread portion threadably engaged with the male thread, the engagement member being movable between an engaged position and a disengaged position, the engaged position being a position at which the first male thread portion is engaged with the first female thread portion, the disengaged position being another position at which the first male thread portion is disengaged with the first female thread portion; and
a unit for maintaining the engagement member at the disengaged position.

Abstract
A power tool has a base, a main unit, a cutter, a bolt, an engagement member, and a unit. The base has a sliding surface slidable on a workpiece, another surface opposite to the sliding surface, and an opening in the base. The main unit is movable in a first direction substantially perpendicular to the sliding surface. The cutter is driven by a electric motor in the main unit to protrude through the opening from the sliding surface during an operation. The bolt extends in the first direction on the first side, a first male thread, and one end supported by the base. The bolt is rotatable about the longitudinal axis. The engagement member has a first female thread threadably engaged with the male thread. The engagement member is movable between an engaged position with the boot and a disengaged position therewith. The unit maintains the engagement member at the disengaged position in a second direction. The rotation of the bolt causes the first male thread portion to thread with respect to the first male thread portion, thereby moving the main unit in the first direction and adjusting a distance of the main unit to the sliding surface.

10. A power tool comprising:
-
a base having a sliding surface slidable on a workpiece, another surface opposite to the sliding surface, and an opening provided through the base between the sliding surface and the another surface;
a main unit supported on a first side of the another surface and movable in a first direction substantially perpendicular to the sliding surface, the main unit including an electric motor; and
a cutter driven by the electric motor, the cutter being configured to protrude through the opening from the sliding surface;
a bolt having a longitudinal axis and extending in the first direction on the first side, the bolt having a first male thread portion and one end supported by the base, the bolt being rotatable about the longitudinal axis; and
an engagement member provided in the main unit and having a first female thread portion threadably engaged with the male thread, the engagement member being movable between an engaged position and a disengaged position, the engaged position being a position at which the first male thread portion is engaged with the first female thread portion, the disengaged position being another position at which the first male thread portion is disengaged with the first female thread portion, wherein rotation of the bolt causes the first male thread portion to thread with respect to the first female thread portion when the engagement member is at the engaged position, thereby moving the main unit in the first direction and adjusting a distance of the main unit to the sliding surface, and the engaged member is maintained at the disengaged position without any external force when the engaged member is at the disengaged position.
