Tube Clamping Hand Tool

摘要

A handheld clamping tool is provided that is adapted to clamp to and secure rounded work pieces, including lengths of tubing without damaging the same. The tool comprises a locking clamp embodiment and a plyer clamp embodiment, whereby the tool includes a pair of jaws with one or more semicircular apertures therealong that align to form rounded openings when the jaws are brought together. In one embodiment, the tool includes a movable jaw and a fixed jaw, along with a handle and grip that are lockable in a static state. Along the upper portion of the locking embodiment is a vice block in which the locking clamp can be held by a bench vice and the tool can support a tube without interaction by the user. In another embodiment, the tool comprises a pair of handles, a pair of jaws, and a fixed pivot point between the handles.

1. A handheld clamping tool, comprising:
a handle having an elongated length, a proximal end, and a distal end; a grip having an elongated length, a proximal end, and a distal end; a fixed jaw extending from the distal end of the handle; a movable jaw pivotably connected to the handle between the distal end of the handle and the fixed jaw; whereby the movable jaw is pivotably connected to the distal end of the grip; an intermediate link having a first end and a second end; the first end of the intermediate link being pivotably and slidably connected to the handle at a position along the length of the handle; the second end of the intermediate link being pivotably connected to the grip along the length of the grip; a turn screw disposed within the handle, whereby a distal end of the turn screw is adapted to secure to the first end of the intermediate link when the grip is moved toward the handle; whereby the turn screw is adapted to adjust the position of the first end of the intermediate link along the length of the handle and operably lock the first end of the intermediate link to the handle when the grip is moved toward the handle; a bias spring disposed between the handle and the movable jaw; a release link pivotably connected to the grip, the release link being adapted to engage the intermediate link and release the first end of the intermediate link from the distal end of the turn screw; whereby the fixed jaw has a semicircular aperture adapted to receive a rounded work piece therein; whereby the movable jaw has a semicircular aperture adapted to receive a rounded work piece therein; whereby semicircular aperture of the fixed jaw and the semicircular aperture of the movable jaw align to form complimentary pairs of rounded openings when the movable jaw is pressed against the fixed jaw.
