A clamp for use with a cutting machine, the clamp comprising: a clamp frame; a low profile clamp head operatively connected to the clamp frame, wherein the clamp head has a clamping surface for pressing on a work surface of a work piece to hold said work piece; and a fixing element, operatively connectable to the clamp frame, for providing a clamping force to the clamp head by fixing the clamp to a support base for the work piece. In embodiments, the clamp head may have a low profile clamp head, made of plastic to prevent damage to a cutting bit.

An angle fixing fixture relates to the field of tooling fixtures and includes: a right-angled triangle shaped positioning block and clamping claws. Each the clamping claw is provided with a clamper, and a position of the clamper on the clamping claw is adjustable. Each the clamping claw is detachably connected to the positioning block. The clamper is located outside the positioning block, and a certain distance is left between the clamper and the positioning block. An end surface of an end of the clamper close to the positioning block is parallel to one of outer side surfaces of the positioning block. The number of the clamping claws is at least two. The angle fixing fixture can meet the need of 90 degrees connection of two plates as well as the needs of other angle connections, and has a simple structure and is easy to use.

A clamping device includes a cylinder, a base body, a movable plate, and holding pins. The movable plate is attached to the base body substantially parallel thereto via two pairs of link arms. The movable plate moves along the operating direction of the cylinder. The movable plate can abut against a width-direction side surface of a workpiece. The holding pins are attached to the movable plate. The holding pins abut against an upper portion of the workpiece.

Systems and methods for a dual sided clamp. More specifically, a clamp with a channel configured to receive a level on a first side of the clamp, and a triangular shaped cutout configured to receive a shaft associated with different sized valves on a second side of the clamp.

A system for preparing a harvested blood vessel for use as a graft during a coronary artery bypass procedure, which includes an elongated platform, a mounting flange extending upwardly from a top surface of the platform adjacent a proximal end thereof for supporting a syringe in a fixed position, and a pair of longitudinally spaced apart clamp holders operatively associated with the top surface of the platform, each clamp holder configured to support a respective vessel clamp, wherein the vessel clamps supported within the clamp holders are adapted to hold a harvested blood vessel immobile therebetween so it can be prepared for grafting.

Disclosed are a mould system and a clamping tong for securing a mould item part in a mould of a mould system. The clamping tong comprises: a primary tong segment comprising a primary clamping surface for applying clamping pressure on a clamping portion of a mould item part; a secondary tong segment coupled to the primary tong segment and comprising a secondary clamping surface for applying clamping pressure on a clamping portion of the mould. The clamping tong being configured to change between a clamping state and a release state, wherein the distance between the primary clamping surface and the secondary clamping surface in the clamping state is shorter than the distance between the primary clamping surface and the secondary clamping surface in the release state.

A clamp for laser level detectors release mechanism is provided. The clamp includes a body, a shaft slidably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. The clamp permits adjusting the position and orientation of the laser level detector while the clamp remains coupled to a work piece.

A bumper apparatus for securing a vehicle bumper during painting and repair is described herein. The apparatus includes a base support structure, a frame coupled to the base support structure, at least one rear coupler arm movably coupled to the frame, at least one front coupler arm movably coupled to the frame via a front coupler attachment, and a front coupler. The front coupler attachment includes a frame portion movably coupled to the frame, a ball portion fixedly coupled to the frame portion, a socket portion configured to receive the ball portion, and an arm portion movably coupled to the at least one front coupler arm. The front coupler is movably coupled to the at least one front coupler arm and is configured to be releasably coupled to the vehicle bumper.

A tool assembly includes a housing, a shaft, a spherical member, and a head. The housing defines a shaft channel. The shaft is rotatably disposed within the shaft channel and includes an exposed portion outside of the shaft channel. The exposed portion defines an engagement channel extending through an outer surface of the exposed portion. The spherical member is disposed within the engagement channel. The head is configured to be engaged with the exposed portion of the shaft. The head includes a detent configured to selectively engage the spherical member.

A system for spacing rafters can include an outer member, an inner member, jaws, and a handle. The handle can be movably connected to the inner member and the outer member. The jaws can be secured to the inner member or the outer member. The handle can be operable to move the jaws with respect to each other to equally space the rafters with respect to each other.
