An opening structure of a tool grip includes a left grip and a right grip that are intersected and pivoted. An elastic connecting strap is provided between the left and right grips. The left grip has at least two left studs. The right grip has at least two right studs. The connecting strap has a length greater than a distance between the left and right grips. One end of the connecting strap has at least two left recessed portions for engagement of the left studs. Another end of the connecting strap has at least two right recessed portions for engagement of the right studs. By selecting the position where the left recessed portions are engaged with the left studs and the position where the right recessed portions are engaged with the right studs, a force that the connecting strap pushes against the left and right grips to open is adjustable.

The present invention provides a blade-replaceable cutting tool, which includes: a first handheld portion and a second handheld portion; the second handheld portion is rotatably connected to the first handheld portion; and further includes a blade mounting plate and a blade, the blade mounting plate is rotatably mounted to the first handheld portion; the blade is detachably mounted to the blade mounting plate. Wherein, the blade mounting plate and the blade may be replaced with a ratchet blade which is detachably and rotatably mounted to the first handheld portion.

An implant extractor including a shaft body and a telescoping push rod extending from the shaft body. An adjustor is engaged with the telescoping push rod for adjusting a length of the telescoping push rod. A support arm extends laterally away from the shaft body and a jaw assembly extends from the support arm. The jaw assembly includes a jaw moveable between a locking position and an unlocking position, and a rocker arm operatively engaged with the telescoping push rod and the jaw. The implant extractor provides a line of force spaced from and substantially parallel to an implant to be extracted. As a consequence, there is substantial clearance for an extension handle such as a C-frame or the like which is oftentimes needed to dislodge the implant from surrounding bone. In addition, the implant extractor is capable of gripping a wide range of sizes of hip stem implant trunnions.

The main fixed handle optionally incorporates two swivel out arms, which can form part of a three-legged base. When operated thus, the jaws and moving handle point generally upwards from the formed base, the moving handle can now be operated by one hand leaving the other free to position the workpiece. The moving handle can incorporate a further locking switch that can be utilised in both a switchable locking position or non-locking position upon a sprung toothed strut between the handles, at least one of which further incorporates a curved resilient portion in order to provide useful sprung closure of the parallel moving jaws upon the workpiece in the locking method. A lanyard can be optimally attached to the swivel out arm ends to provide the user with a chest mounted portable vice.

A hand operated gripping tool has a first handle (301), a first jaw (201) connected with the first handle, a second handle (302) pivotably connected with the first handle to permit relative pivoting movement of the second handle with respect to the first handle and a second jaw (202) connected with the second handle. One of the first jaw and second jaw is a removable jaw and the removable jaw is push-fit attachable to the respective handle.

A pot gripper comprises a first lever and a second lever joined at a fulcrum. The first lever has a first jaw extending from the fulcrum, and the second lever has a second jaw extending from the fulcrum. The first jaw and the second jaw define a clamping area for a pot when the first lever and the second lever are rotated from an open position into a closed position. The first jaw has at least one support slot, the support slot being shaped to fit to the contour of a gripping area of the pot to be held in the clamping area. The first lever has a first locking feature and the second lever has a second locking feature. The first locking feature engages with the second locking feature in the closed position so that the first lever and the second lever are locked in the closed position.
