The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The stop assembly has a locking assembly that allows it to be locked to the straight edge. The straight edge clamp body can include sections that are adapted to be connected together to form the overall length of the straight edge clamp.

A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.

An air chuck includes: a finger support part including a pair of fingers and a pair of lock shafts; a chuck main body part including an operation mechanism operable to open and close the fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part.

A method and apparatus for maintaining a fixed distance between two cabinets during installation are provided. An elongated rail with two stops and two clamps are used. The stops are fixed to the elongated rail with opposing faces placed the fixed distance apart. The assembly is placed between the cabinets and a clamp is used to pinch a cabinet wall of each cabinet against a stop. The cabinets are installed and the apparatus is removed. In some embodiments a second apparatus may be used, one at the top of the cabinets and one at the bottom.

The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The straight edge clamp body includes at least two sections that are hinged together to allow the sections to be folded upon one another when not in use and unfolded when in use.

A clamping tool of the type including a C-shaped body and a drive screw with a threaded portion in mechanical communication with a threaded receiver in one end of the C-shaped body and including at least two threaded receivers in one end of the C-shaped body, each adapted to separately and independently receive and support the threaded portion of the drive screw. A backstop may be included with a backstop pin extending from a surface of the backstop and at least two non-collinear backstop bushings in a second end of the C-shaped body. The at least two non-collinear backstop bushings may each be adapted to receive and support the backstop pin of the backstop, thereby providing more than one position of the backstop on the C-shaped body.

A pallet, manufacturing system, and method for transporting and assembling different electrical connectors are provided. The pallet includes first and second jaw assemblies spaced apart from a connector support. The jaw assemblies include jaw plates with gripping edges that form a contoured opening therebetween. As the jaw assemblies move toward one another, dimensions of the contoured opening decrease such that the gripping edges contact and grip an electrical connector placed in the contoured opening. The jaw assemblies are connected to each other by a synchronization device that synchronizes motion of the jaw assemblies and centers the jaw assemblies about an alignment point on the pallet. The pallet accommodates a number of different sizes and/or types of electrical connectors.

The present invention provides an improved release mechanism for clamping tools where problems of thread slipping due to worn out thread can be reduced by the structure of a plunger with a small diameter section and the engagement of the thread shaft is made more secure by the cam action on account of the shape of the plunger. A protrusion extends from a push button on a top portion of the half-threaded nut. Threads are formed on an upper portion of the hole for engaging the threaded shaft. The middle portion of the plunger is made to have a section of small diameter allowing the protrusion to be pushed downward in a normal position and allowing the protrusion to rely on the resilient power of the helical spring to push it upward into the small diameter section.

A centering clamping apparatus has a housing (1) with a centering element (2) mounted to be displaceable along a longitudinal axis between an open position and a clamping position. A finger element (3), mounted with centering element (2), is displaceable transversely to the longitudinal axis between a retracted position and an extended position. The finger element (3) is operatively connected to an adjusting member (4). The adjusting element (4) is mounted to be displaceable in the centering element (2). A blocking device (5) is provided on the centering element (2). The blocking device (5) either precludes a relative movement between the housing (1) and the centering element (2), with the finger element (3) fully retracted, or precludes a relative movement between the centering element (2) and the adjusting member (4), with the finger element (3) fully extended.
