  • Patent number: 9604378
    Abstract: A cutting tool includes a fixed blade having a cutting surface and a movable blade having a cutting surface. The movable blade is rotatable between a receiving position in which the cutting surfaces are spaced and a cutting position in which an object disposed between the fixed and movable blades is cut by the cutting surfaces. A return spring member is connected to the movable blade. The spring member stores energy when the movable blade is rotated from the receiving position to the cutting position. The spring member returns the movable blade to the receiving position when the stored energy is released.

  • Patent number: 8024864
    Abstract: A ratcheting cutting tool for plastic pipes having first and second, elongated rigid members pivotally mounted to each other. Each rigid member has a handle and the first rigid member additionally has an anvil at an end opposite from its handle. A spring-biased, knife blade member with a cutting edge and with a plurality of ratchet teeth is pivotally mounted to the first member. The tool further includes drive and catch pawls pivotally mounted to the respective rigid members. In operation, the handles of the rigid members can be repeatedly squeezed together to progressively move the cutting edge of the knife blade member in a step-by-step manner toward the anvil to cut through a plastic pipe positioned therebetween.

  • Publication number: 20110219626
    Abstract: A drill cutting attachment for severing an electrical conductor includes a housing, a stationary cutting blade connected with the housing, a movable cutting blade pivotally connected with the stationary cutting blade for displacement about a given cutting pivot axis between open and closed positions relative to the stationary cutting blade, and a pawl and ratchet arrangement for displacing the movable cutting blade from the open position toward the closed position, thereby to sever an electrical conductor positioned between the blades. The pawl and ratchet arrangement includes a transport pawl member that is longitudinally reciprocated by a rotary drive shaft via either an eccentric and crank arm drive arrangement, or a cam and follower drive arrangement. The drive shaft has a free end with a hexagonal cross-sectional configuration for connection with the chuck of an electric drill, and an attachment sleeve connects the housing with the electric drill body.

  • Publication number: 20110185577
    Abstract: An improved hand-held cutting tool includes a first double-sided handle member having a front open cavity for receiving an anvil member. A second double-sided handle member having an upper open cavity for receiving a biased auxiliary handle therein and a front open cavity for receiving a blade holder therein. The first and second handle members are pivoted between a first open work piece placement position and a second open blade replacement position. The first open position allows a work piece to be placed on the anvil member to be cut and the second open position allows access to the blade holder for blade replacement without using tools. The auxiliary handle is biased out of the upper open cavity in the first open position to allow a user to grasp the auxiliary handle and the first handle member with one hand to easily achieve an initial cutting operation.

  • Patent number: 7966681
    Abstract: A multi-function pipe cutting and fitting tool includes a spring biased connecting rod, a pair of plier teeth and a pair of friction teeth. The spring biased connecting rod improves the pipe cutting function of the tool by improving the operation of a movable jaw toward engagement of a fixed jaw. The pair of plier teeth positioned on one side of the tool allows a user to firmly grip a pipe or other object to be held in place. The pair of friction teeth positioned on an opposite side of the tool allows a user to more reliably engage an object such as a cap on a can of glue. The inclusion of all of these features in the same tool allows a user to perform multiple functions easily and more rapidly.

  • Publication number: 20110126414
    Abstract: A tool for cleaving a plastic optical fiber has a body with a cleaving aperture at the insertion face of the body and through which the termination end section of the plastic optical fiber is inserted and in which an operative section is positioned upon inserting the plastic optical fiber into the tool. A cutting blade has a cutting edge and is moveable along a cutting path between a first operative position at which the cutting edge is spaced from the cleaving axis and a second operative position at which the cutting edge intersects the cleaving axis to cleave the plastic optical fiber to create an optical finish on an end surface of the operative section of the plastic optical fiber. A clearance region is located at the termination face of the body and generally aligned with the cleaving aperture and in which the termination end section may deflect upon engagement of the cutting blade with the plastic optical fiber.

  • Patent number: 7886446
    Abstract: A pair of pipe cutting pincers includes a pincers body having a first handle and a second handle pivotally assembled together. The first handle has its front end pivotally combined with a pipe-cutting member disposed with a cutting blade and its rear end bent toward a second receiving groove to form a pivotally driven member. An elastic member positioned between the first and the second handle has one end hooked on the first handle and the other end hooked with the rear end of the pivotally driven member for pulling the pipe-cutting member to carry out reciprocating shifting. A pivotal actuating member is rotatably assembled in the second handle to resist against the lower end of the pivotally driven member. In using, the pivotally driven member is actuated by the elastic member to move and make the pivotal actuating member rotate and drive a cutting edge to cut off a pipe.
