A siding straightening tool includes two arms engaged with one or more ratchets; one or more spikes extending from the one or more ratchets; a release engaged with one of the two arms and to allow the arms to release; and a mold extending from the one or more arms, the mold having a groove; the two arms clamp together, thereby bringing the spikes toward each other; the mold is ratcheted down to straighten a piece of siding; and the two arms pivots via the one or more ratchets thereby engaging the mold and disengaging the mold with the siding.

A workholding clamp for securing a workpiece to a work surface comprised of a fixed body secured to the work surface and having a first inclined surface; a sliding jaw having a second inclined surface residing against and parallel to the first inclined surface, a clamp face and at least one obround opening; and at least one clamping fastener residing within the at least one obround opening and being tightened to cause the second inclined surface to slide against the first inclined surface. A workholding pivot clamp for securing a workpiece to a work surface, and a work stop for reliably locating a workpiece relative to a work surface are also described.

A fixing device adapted to fix at least one needle-shaped member comprises a fixing base and a fixing mechanism. The fixing base has at least one positioning groove disposed at a front end of the fixing base. The needle-shaped member is adapted to be positioned in the positioning groove. The fixing mechanism has at least one pressing protrusion at a front end of the fixing mechanism. The pressing protrusion is adapted to press and hold the needle-shaped member in the positioning groove.

A clamping device includes a first clamping segment which has a first mounting flange and a tubular member extending axially away therefrom. A first bore extends through the first mounting flange and the tubular member. The first mounting flange is configured for attachment to a rotatable spindle of a machine tool. The clamping device includes a draw bar assembly which has an axially extending elongate shaft. The elongate shaft extends through the first bore of the first clamping segment. A biasing unit is mounted on or in the tubular member. A locking member is removably secured to the elongate shaft such that the biasing unit is compressed between the locking member and a portion of the first clamping segment. The biasing member remains compressed when the first clamping segment is separated from the spindle of the machine tool.

Pressing jaws for opposite arrangement in crimping pliers, the pressing jaws having ribs, which extend in a rib longitudinal direction and move into each other during pressing. A guide surface extending transversely to the rib longitudinal direction outside of a working region of the ribs is formed, which guide surface interacts with a guide protrusion extending from the opposite pressing jaw. In another version, the pressing jaws have ribs, which are designed to mesh with each other and which have a rib longitudinal direction. Crimping pliers comprise two plier jaws, which are provided with oppositely arranged pressing jaws having ribs, which extend in a rib longitudinal direction and which, during pressing, move into each other and delimit a pressing jaw opening.

A frame block clamp includes first and second block portions dimensioned and configured to provide first and second tube receiving apertures for snugly receiving a predetermined tube; and to provide first and second “V” configured recesses in respective first and second side portions when portions of said first and second block portions are cooperatively engaged. The frame block clamp further includes a retaining spring dimensioned and disposed to urge together predetermined portions of the first and second block portions to ultimately secure a tube in the first or second receiving apertures. The frame block clamp is ultimately secured in a vise to allow a person to service the tube secured in the first or second receiving aperture.

An apparatus configured to assist an operator in connecting electrical connectors. The apparatus includes a first U-shaped cradle and a second U-shaped cradle. Each of the cradles has a contact surface on a front side that is configured to contact a flange on an electrical connector. Each of the cradles also includes a jaw mount configured to mount on a jaw member of a bar clamp.

A locking assembly for locking a portable electronic device to a work surface. The locking assembly comprises a clamp assembly including an elongated bar that extends between a first end and a second end. The clamp assembly further includes a first jaw and a second jaw moveable along the elongated bar for clamping to a work surface between the first and second jaws. A connector extends from a first connector end that is pivotally connected to the locking assembly to a second end that can be connected to the portable electronic device. The connector securing the portable electronic device to the work surface while permitting it to pivot with respect to the locking assembly.

A clamp head adapter (100), including: an adapter body (102); a slot (104) disposed on a first side (106) of the adapter body and configured to receive and secure therein a clamp head (24); and a groove (110) recessed into a body surface (112) of the adapter body opposite the first side. The groove includes a vertex (130); a first bevel angle (132) between a normal line (134) normal to the body surface and a first line (136) between the vertex and a first corner (138) of the groove, and a second bevel angle (150) between the normal line and a second line (152) between the vertex and a second corner (154) of the groove. The first bevel angle and the second bevel angle together form a groove angle (156) that is less than 90 degrees.

Certain exemplary embodiments can provide a system that comprises a bar and a pair of clamps. The bar defines a set of spaced apertures. The pair of clamps comprises a first clamp and a second clamp. Each of the first clamp and the second clamp comprises a first portion and a second portion.
