A multi-functional clamping device is disclosed. The multi-functional clamping device includes a handle portion having a vice grip handle, and a clamping portion coupled to the handle portion. The clamping portion includes opposing clamps. The multi-functional clamping device also includes an accessory mount coupled to the clamping portion. The position of the accessory mount is adjustable or non-adjustable with respect to the clamping portion. Further, the multi-functional clamping device includes an accessory locking fixture coupled to the accessory mount.

A connector contains a body including: a first inserting orifice, a second inserting orifice, a first fixer, and a second fixer. The first inserting orifice is defined on a first end of the body, and the second inserting orifice is formed on a second end of the body opposite to the first end of the body, such that a connection rod for connecting two main woodworking clampers is inserted into the first inserting orifice and the second inserting orifice. The first fixer is inserted into the first inserting orifice from one side surface of the body to fix the connection rod, and the second fixer is inserted into the second inserting orifice from the one side surface of the body to position the connection rod more securely.

A work holding device that secures a workpiece includes a first support column, a second support column, and a plurality of part fixturing anchors. The first support column and the second support column are coupled to one another forming a longitudinal loading envelope having a width-wise dimension, a height-wise dimension, and a length-wise dimension. At least one of the support columns includes a plurality of part fixturing recesses passing through the support column in the width-wise dimension and arranged within the height-wise dimension and the length-wise dimension of the longitudinal loading envelope. The part fixturing anchors extend through the support column at the part fixturing recesses into the longitudinal loading envelope and couple the workpiece to the first and second support columns.

The present invention comprises an improved clamp for securing two members together. The invention includes a pair of clamp jaws that may be positioned in spaced relation to each another and adjusted in three dimensions.

This disclosure generally pertains to various accessories for use with bar clamps to enhance the capabilities and functionality of the bar clamps. The accessories described in detail herein include removable and replaceable bar clamp attachments, bar extenders, and stability stands for use with a bar clamp.

A hold-down clamping apparatus comprising a hold-down clamp with body having a top lip and pair of guide legs disposed between a central screw in the body and a support having holes in vertical alignment with the legs and the screw for securing and holding down a sheet material for processing. The screw is threaded through the support screw hole as the legs are inserted within support holes until the top lips contacts the sheet material to hold down the material and to prevent twisting of the hold-down clamp. Supports with clamps may be fastened to tools or supports. In one embodiment, the support has a grid of holes for securing a plurality of materials with hold-down clamps. In another embodiment, the hold-down clamp comprises a top lip and a guide beam slotted in a support and secured.

A device for connecting two clamps, each of which has a rail, including a housing that has two insertion openings, which point away from each other and each of which has an adjoining insertion channel, for inserting a respective rail. The device also includes at least one adapter piece which can be inserted into one of the insertion openings and which reduces the free opening cross section of the insertion channel in order to insert a rail with a different cross-sectional area. The adapter piece has a lining which adjoins a collar. The lining rests against the wall of the insertion channel at least in some regions and forms an insertion channel with a reduced cross section in the inserted state, and the collar rests on an end face of the housing.

A clamping system may include a bottom clamp bar with a top surface configured to interface with an object to be held. The clamping system may include a top clamp bar with a bottom surface configured to interface with the object to be held. The clamping system may include a fastening member that passes through a first hole in the top clamp bar and a second hole in the bottom clamp bar. The clamping system may include a pivoting receiving member coupled to a portion of the fastening member below the top surface of the bottom clamp bar. The clamping system may include a pivoting pin arranged below the top surface of the bottom clamp bar and engaged with a side of the pivoting receiving member to form a pivot point enabling the fastening member to pivot about the pivot point.

A mechanical clamp may include an actuator having an end that is movable. The mechanical clamp may include a base link with a first link end configured to be movably coupled to a link pivot point and with a second link end movably coupled to the end of the actuator. The mechanical clamp may include a clamp arm including: a clamp interface, a first arm coupling element, and a second arm coupling element mounted to a clamp pivot point, where the first arm coupling element and the clamp interface are configured to rotate about the clamp pivot point. The mechanical clamp may include a compressible link the couples the second link end with the first arm coupling element, where rotation of the second link end about the link pivot point causes the compressible link to exert force against the first arm coupling element.
