Abstract: An electric cable cutter used with a hand-held tool includes a housing; a pair of cutting blades supported by the housing; a pair of orthogonal gears; a drive shaft with an eccentric shaft portion attached to an output gear of the pair of orthogonal gears; a differential gear mechanism which decelerates a rotation of the drive shaft; and an Oldham coupling which corrects an eccentric rotation of an output gear of the differential gear mechanism. A circular-arc-shaped outer surface of the one cutting blade is supported by the other cutting blade so as to be openable and closable. The pair of cutting blades is provided with an outer toothed portion engaging with an output gear of the Oldham coupling. An input gear of the pair of orthogonal gears is connected through an adapter pin to the hand-held tool attachable and detachable through a one-touch operation.

Abstract: A manual cable cutter in which a fulcrum of at least one handle is set to a projecting piece provided to a cutting blade connected to the other handle; a middle portion of the one handle and a rear end portion of the cutting blade are connected through a slider mechanism, and a point of the connection is set as an action point of the handle; an angle between the fulcrum of the handle, and a contact point between the cutting blades is set in an appropriate range; and a ratio among a length between the center of the support shaft and the fulcrum of the handle, a length between the fulcrum and the action point of the handle, and a length between the action point of the handle and the center of the support shaft is set in an appropriate range.

Abstract: Provided is an electric cable cutter that easily cuts a cable.

Abstract: A manual cable cutter includes a pair of handles linked to each other in upper parts thereof with two frame plates, one of the pair of handles being adapted as a stationary handle and the other as a rocking handle; a stationary cutting blade having a basal terminal part fixed, with soft bolts capable of being sheared, onto one of the two frame plates in a state superposed on the one frame plate; a rotary cutting blade furnished on an arcuate outer surface thereof with a continuously formed toothed part and pivotally supported rotatably on the stationary cutting blade; a first energizing spring and a second energizing spring disposed between the two frame plates; and a backstop claw meshed with the toothed part of the rotary cutting blade under pressure of the first energizing spring, and a feed claw meshed with the toothed part of the rotary cutting blade under pressure of the second energizing spring and disposed in an upper part of the rocking handle, the backstop claw and the feed claw both being disposed

Abstract: A reinforcing steel bar cutter includes a base, a pair of bearing plates erected on the base, a handle shaft pivotally attached to one of the pair of bearing plates, a stationary blade and a movable blade provided with depressed parts and interposed between the pair of bearing plates, and a posture-retaining wall formed on at least one of the pair of bearing plates for preventing the reinforcing steel bar inserted into the depressed parts from warping while the reinforcing steel bar is being cut. The stationary and movable blades have opposed cutting blade parts to each of which a relief angle is imparted. The movable blade is connected to the handle shaft and rotated relative to the stationary blade by rocking motion of the handle shaft to cut the reinforcing bar.
