Shearing tool
First Claim
Patent Images
1. A method for operating a shearing tool comprising:
- providing a shearing tool with a housing with a blade set having first and second blades, a motor drivingly coupled to the blade set so that at least one of the first and second blades move in reciprocal motion, the motor having an output shaft that is rotatable in a first rotary direction and a second rotary direction that is opposite the first rotary direction, a first switch positioned on the housing and a second switch positioned in close proximity to the first switch so that both switches are operable using a single hand, and a controller configured to operate the motor in response to a state of the first switch and the second switch;
actuating the first switch to rotate the motor in the first rotary direction; and
actuating the first and second switch to cause the motor to enter an anti-bind mode where the motor alternatively rotates in the first and second rotary directions, and the anti-bind mode is only entered upon simultaneous actuation of the first and second switch.

Abstract
A method for operating a shearing tool that includes: operating a first switch to control a drive unit to drive a blade of a blade set; and operating a second switch to cause the drive unit to operate in an anti-binding mode in which a direction of an input to the drive unit is alternated at least twice. A shearing tool is also provided.

6. A method for operating a shearing tool comprising:
-
providing a shearing tool having a housing, the housing having a handle thereon, a first switch located on a first side of the handle, and a second switch located on a second side of the handle, a first blade and a second blade extending out from a front portion of the housing, and a motor operatively connected to at least one of the first blade and second blade; actuating the first switch to rotate the motor in a first direction; and actuating the second switch, while continuing to actuate the first switch, to cause the motor to operate in an anti-binding mode and rotate the motor in a second direction opposite the first direction, wherein the anti-bond mode is only actuated when both the first switch and the second switch are simultaneously actuated. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
