  • Patent number: 9743945
    Abstract: A laparoscopic scissor instrument can include a scissor assembly pivotally coupled to an elongate shaft. The scissor assembly can be formed of scissor blades having pivot posts thereon. The pivot posts can engage apertures on the elongate shaft, thus eliminating the need for a through-pinned pivot connection of the scissor blades. The scissor blades can also include actuation posts thereon. An actuation mechanism can include a slot to engage the actuation posts and open or close the blades of the scissor assembly. The scissor assemblies described herein can have a relatively low operational height such that they do not extend beyond a diameter of the elongate shaft during opening and closing of the scissor assembly.

  • Publication number: 20130091713
    Abstract: A branch scissors structure with an adjustable structure includes a main body and an adjustable structure. One handle of the main body has a wedging opening at a front end near a blade, and a slot is recessedly formed at a bottom wall of the wedging opening. The adjustable structure located corresponding to the wedging opening has a connecting block, a restricting block, a pressing unit and a restricting unit. The position of the restricting block can be adjusted, so that the restricting block can protrude and lean against the outer periphery of the blade through the opening of the connecting block and forms a secure positioning when the restricting unit engages with the restricting slot. The blade can be restricted by the restricting block, and the angle between the handle and blade cab be further limited.

  • Patent number: 8393084
    Abstract: An adjustment device for manual cutting tools is provided. The cutting tool for which the device is intended takes the form of pruning shears having two arms with the respective cutting blades thereof hinged to one another by a transverse bolt forming the main element of the device. A tightened nut for locking the bolt is provided with a transverse hole into which a lateral locking screw is screwed, thereby enabling the hinge to be adjusted. The nut and the locking screw are positioned in a recess in the cutting blade such that the nut cannot rotate when the bolt is being manipulated using a protrusion of the nut housed in a cavity in the cutting blade. The through-hole provided in the cutting blade for the bolt includes a bushing which enables the bolt to be better adjusted in the hole.

  • Patent number: 8365418
    Abstract: A cable tie removal tool for cutting a cable tie off of an underlying structure with which the cable tie is engaged. The tool has an opposed pair of cutting members each having a cutting edge, the cutting members movable between an open position in which the cutting edges are spaced from one another and a cutting position in which the cutting edges are close together or touching. The tool also has a mechanical structure that holds at least one cutting member off of the underlying structure as the cutting members are moved from the open to the cutting position.

  • Patent number: 8327548
    Abstract: A multi-function blade-and-anvil type cutting tool that uses standard type razor blades includes a blade-and-anvil section connected to a first handle portion and a non-tool blade holder and a blade clamp assembly connected to a second handle portion. The standard blades are able to be changed with out tools when the first and second handle portions are moved from a first open position to a second open position to allow the blade holder and the clamp assembly to pivot with one another causing a screw and O-ring latch to move away from a latching slot in the second handle portion. This movement positions the razor blade between the screw and O-ring latch and a blade clamp guide element for easy removal. Each handle portion having a gripping cover disposed thereon. One of the handle portions has a sliding storage tray disposed therein for storing replacement razor blades.

  • Patent number: 8266804
    Abstract: A garden shears includes a pressing member, a holding member, a cutting member and a ratchet. An aperture of the cutting member combines with an aperture of the pressing member for a pivot. The holding member and the ratchet are assembled together at an assembling portion of the pressing member, and teeth of the ratchet engage with a pawl of the cutting member such that the pressing member, the holding member and the ratchet have different pivot points. An opening between the blade and the anvil is smaller than an opening formed between the handle and the holding member. Since the opening formed between the handle and the holding member is larger than the cutting opening between the blade and the anvil, a stronger cutting torque is applied to increase the clipping strength derived from the anvil and the blade.

  • Patent number: 8225513
    Abstract: A pair of gardening shears include a main cutter, a secondary cutter pivotally connected with the main cutter, a force arm pivotally connected with the main cutter and engaged with the secondary cutter to drive the secondary cutter to pivot relative to the main cutter, and a connecting plate mounted on the secondary cutter and the force arm. Thus, the secondary cutter and the force arm are sandwiched between the main cutter and the connecting plate so that the secondary cutter and the force arm are moved smoothly and stably by limit of the main cutter and the connecting plate so as to facilitate the user performing the pruning action.

  • Patent number: 8166659
    Abstract: A garden shears has a first shear, a second shear, a separator, an engaging member and two joined pressing arms. A cutting portion of the first shear is offset from the handle portion, and central portion has a centrally positioned first pivot hole and a first eccentric pivot hole. A central portion of the second shear has a second pivot hole. A side of the second shear has a strip-shaped extending portion with an end bent towards the other side of the second shear and having an engaging gear rack, which defines an escape region. An arcuate limiting guide groove is disposed between the second pivot hole above the escape region. The engaging member has an arcuate engaging tip edge with a protrusion. The pressing arms are bi-leveled with a beveled connection and have a handle at a lower portion and a second eccentric pivot hole at an upper portion.
