Abstract
A rechargeable shear (1) includes: a motor (5) having a rotor (21) that is rotatable relative to a stator (20); a motor housing (4), which houses the motor (5); a grip housing (8) connected to the motor housing (4); a battery-holding housing (9) connected to the grip housing (8); and a shear part (3) disposed forward of the rotor 21 and operably driven by the rotor (21). The motor (5) may be brushless. The shear part (3) may be rotatable relative to the motor housing (4) using a manipulatable ring (85) and a detent system (89, 92-94). A light (48) for illuminating the shear part (3) and a workpiece being cut thereby may be provided on the grip housing (8) or the battery-holding housing (9).
Claims20
A rechargeable shear comprising:
- a brushless motor having a rotor that is rotatable relative to a stator and that rotatably drives a rotary shaft;
- a fan disposed on the rotary shaft forward of the rotor;
- a sensor circuit board disposed rearward of the rotor;
- a housing including:
- a motor housing, which houses the brushless motor;
- a grip housing having a loop shape and being connected to a rear part of the motor housing;
- and
- a battery-holding housing connected to a lower part of the grip housing;
- a shear part disposed forward of the rotor and configured to perform a shearing operation in response to rotation of the rotor;
- a control circuit board disposed inside the grip housing and configured to control energization of the brushless motor;
- and
- a light provided on an upper surface of the housing rearward of the fan and oriented to illuminate an upper side of the shear part.
A rechargeable shear comprising:
- a housing including a motor housing, a grip housing and a battery-holding housing;
- a brushless motor disposed in the motor housing and having a rotor that is rotatable relative to a stator;
- a shear part disposed forward of the rotor and configured to perform a shearing operation in response to rotation of the rotor;
- and
- a light provided on an upper surface of the housing rearward of a forward end of the brushless motor and oriented to illuminate an upper side of the shear part;
- wherein:
- the grip housing has a loop shape and is connected to a rear part of the motor housing;
- and
- the battery-holding housing is connected to a lower part of the grip housing.
