CUTTING TOOL
A cutting tool includes a housing; a motor; a plunger; a base; and a plate. The motor is accommodated in the housing. The plunger has an end portion to which a blade is attachable. The plunger is configured to be reciprocated by the motor. The base is attached to the housing. The base is configured to slidingly move along with the housing over a workpiece. The base has a base surface at a side opposite to the housing. The plate is detachably mounted on the base at a position on the base surface for facilitating a curved cut. The plate is formed of a resin. The plate has a length shorter than a length of the base surface in a cutting direction. The plate has a pawl for engagement with the base.
1 . A cutting tool comprising:
a housing;
a motor accommodated in the housing;
a plunger having an end portion to which a blade is attachable, the plunger being configured to be reciprocated by the motor;
a base attached to the housing, and configured to slidingly move along with the housing over a workpiece, the base having a base surface at a side opposite to the housing; and
a plate detachably mounted on the base at a position on the base surface for facilitating a curved cut, the plate being formed of a resin and having a length shorter than a length of the base surface in a cutting direction, the plate having a pawl for engagement with the base.
2 . The cutting tool according to claim 1 , wherein the plate has a rear edge portion in the cutting direction, the rear edge portion being disposed below a gravitational center of a tool body assuming that the cutting tool is postured such that the base is disposed below the housing.
3 . (canceled)
4 . The cutting tool according to claim 1 , wherein the base has a front edge portion in the cutting direction; and
wherein the plate has a front edge portion in the cutting direction at which the pawl is provided to engage with the front edge portion of the base so as to detachably fix the plate to the base.
5 . The cutting tool according to claim 1 , wherein the base has a side surface; and
wherein the plate has a rear edge portion in the cutting direction at which the pawl is provided to engage with the side surface of the base so as to detachably fix the plate to the base.
6 . The cutting tool according to claim 5 , wherein the side surface of the base is formed with a groove for engagement with the pawl.
7 . The cutting tool according to claim 1 , wherein the plate is fixed to the base with a screw.
8 . The cutting tool according to claim 1 , wherein the base has a front portion in the cutting direction formed with an insertion space for allowing passage of the blade, the insertion space being generally U-shaped opened at the front edge portion; and
wherein the plate is formed in generally U-shape for covering the front edge portion of the base surface.
9 . The cutting tool according to claim 1 , wherein the plate comprises a plate body, and a pair of protruding parts which is extendible rearward from the plate body in the cutting direction and retractable into the plate body.
10 . The cutting tool according to claim 1 , wherein the base is formed of a steel material.
11 . (canceled)
12 . The cutting tool according to claim 1 , wherein the plate has a contact surface configured to contact the workpiece, the contact surface being coated with a friction-reducing agent.
13 . The cutting tool according to claim 1 , further comprising an antislip part provided on a front edge portion of the plate.
14 . (canceled)
15 . The cutting tool according to claim 13 , wherein the antislip part has a slope portion protruding from the front edge portion of the base toward the housing and sloping rearward in the cutting direction.
16 . The cutting tool according to claim 13 , wherein the antislip part is formed of an elastically deformable material.
17 . (canceled)
18 . The cutting tool according to claim 13 ,
wherein the plate has a front edge portion in the cutting direction, the antislip part being provided on the front edge portion of the plate.
19 . The cutting tool according to claim 18 , wherein the plate has a plate surface at a side opposite to the housing, the antislip part providing a coefficient of friction higher than that of the plate surface.
