A dual compression and distraction tool for surgical operations, the tool including a first arm having a first pivot axis, a second pivot axis, a first lever, and a first dual purpose jaw, a second arm having a third pivot axis, a fourth pivot axis, a second lever, and a second dual purpose jaw, wherein, in a first position, the first arm is pivotably connected to the second arm such that the first pivot axis is merged with the third pivot axis, to form an distraction tool, and wherein, in a second position, the first arm is pivotably connected to the second arm such that the second pivot axis is merged with the fourth pivot axis, to form a compression tool.

The invention relates to a manually actuated hand tool (2) which might e.g. be embodied as pliers (1). According to the invention, the hand tool (2) comprises a display device (13) by which it is possible to display a hand tool identification (16). It is possible to electrically modify the displayed hand tool identification (16). It is possible to permanently display the hand tool identification (16) without electric powering. Preferably, for this purpose the display device (13) comprises a so-called electronic paper.

A pliers includes a first member and a second member pivotally coupled to the first member. The first member and the second member each include a head and a handle having a recessed area with a non-circular cross-sectional shape and an exposed end portion adjacent the recessed area. The recessed area is bounded by a forward lip and a rear lip. The forward lip has a cross-sectional area not greater than a cross-sectional area of a portion of the handle adjacent the forward lip and opposite the recessed area. The pliers also includes a first grip positioned on the recessed area of the handle of the first member and a second grip positioned on the recessed area of the handle of the second member. The end portions of the handles are made of metal.

A device for installing an elastic sealing ring on an electronic device includes a clamp module and a pressing module. The clamp module includes a sliding column defining two grooves, two linkage plates, and two pins secured on the bottom end of the linkage plates. The pressing module includes a bracket and a knockout plate. The linkage plates are rotatably installed on the bracket and the sliding column can slide relative to the bracket. The knockout plate can slide relative to the bracket, to install the sealing ring on an electronic device.

Disclosed herein is a grip comprising an internal bore with an opening having an internal tapered edge. The grip can engage with a tool or a piece of sports equipment. Further disclosed herein is a method of installing a grip onto a tool or piece of sports equipment, including providing a grip having a tubular body; grinding an open first end of the body, wherein the open first end comprises a greatest diameter closest to the exterior of the bore and tapers internally at an angle towards the interior of the bore; providing a shaft or handle; applying an adhesive to a top portion of the handle; sliding the handle into the grip bore until the shaft contacts the a capped second end of the grip; and coupling a surface of the bore to the handle by allowing the adhesive to dry.

Two-stage pincers as hand-operated tools, especially multifunctional wrenches automatically switching between two stages and having a large-opening jaw and a high clamping force, comprising: a first main structure (1), a second main structure (2), a handle (3), a pawl (4), a first pin (5), a second pin (6), a first connecting rod (7), a second connecting rod (8), a first stop nut (9), a second stop nut (10), a first preloaded spring (11), a second preloaded spring (12), a supporting spring (13), a small pin (15), a second small pin (14), a third pin (18), a fourth pin (16) and a fifth pin (17). The two-stage pincers overcome problems of the existing hand-operated tools, i.e. wide varieties, inconvenience to carry and low efficiency.
