  • Patent number: 7275323
    Abstract: A long-handled shears with a detachable connecting device has an operational grip stick with an elongated tube and a wire, a grass shears, and a connecting device attached between the grip stick and the grass shears. The ball is attached to the wire of the grip stick. The base is mounted on the elongated tube, allows the wire to extend through the base and engages the grass shears by a clamp. The engaging block is movably mounted inside a grip of the grass shears and has a ball recess. When the grip of the grass shears is compressed, the engaging block moves aside to reveal the ball recess to allow the ball to enter the ball recess. Then, the handle is released to lock the ball inside the ball recess. By engaging the ball and the engaging block, the grass shears detachably attaches to the grip stick conveniently.

  • Patent number: 7055245
    Abstract: A nail clipper for pets has a first semi-spherical or semi-elliptical part which is hollowed-out with a circular or elliptical hole with a blade formed on a rim of the hole, and a second semi-spherical or elliptical part having a shape matching the outside of the first part and a blade formed on a rim thereof. By placing the pet's nail in the hollowed-out hole of the first semi-spherical or elliptical part and rotating the second part along the outside of the first part, the blades of the first and second parts come together to cut the pet's nail, producing smooth nail edges cut in a semi-circular shape in a single cutting action.

  • Patent number: 6625888
    Abstract: A pruning device includes a blade mounting jaw and an opposing jaw. A blade is removably mounted on a blade mounting portion of the blade mounting jaw to cut vegetation positioned between the jaws as the jaws are closed. A blade retainer is movable between a blade retaining and blade releasing positions with respect to the blade mounting portion and has a forward blade engaging portion. In its blade retaining position, the blade retainer secures the blade to the blade mounting portion. A forward edge portion of the blade is received between the forward blade engaging portion and the blade mounting portion. A rearward blade engaging structure and the blade mounting portion support a rearward portion of the blade. In its releasing position, the blade retainer releases the blade for replacement. Grip portions are operatively connected to the jaws to open and close the jaws.

  • Patent number: 5950314
    Abstract: A step-separating shearing tool includes a first handle and a second handle. A first blade portion is connected to the first handle, and a second blade portion, which includes an L-shaped slot, is hinge-connected to the first blade portion and to the first handle. A rocker arm connects the second handle and the first blade portion. The step-separating shearing tool also includes an automatic step-separating mechanism. This mechanism includes: a double-oscillating rod, which is hinge-connected to the rocker arm; a slider on the double oscillating rod, which is received in the L-shaped slot of the second blade portion; and a torsion spring connected between the rocker arm and the double oscillating rod. When the shearing tool is used in a cutting operation for cutting items having a relatively small diameter, the slider is located in a short slot portion of the L-shaped slot during the entire cutting operation.
