A retainer is placed on a retainer holding portion formed on a sample chip worktable. With an operation of a button, a take-out support mechanism operates. That is, an upthrust pin moves upward. With this process, an orientation of a sample chip stored in the retainer is changed from a horizontal orientation to an inclined orientation. A plurality of openings through which the upthrust pin passes are formed in the retainer.

A tool cabinet includes a cabinet body, a hanging board having a plurality of hanging portions, two slide rail units, and at least one counterweight device. Each of the slide rail units is connected between the cabinet body and the hanging board and extends in an up-down direction, such that the hanging board is movable in the up-down direction relative to the cabinet body between a lifted position and a lowered position. The counterweight device includes a constant force spring having free and fixed ends that are respectively connected to the hanging board and the cabinet body, and providing a resilient force against the weight of the hanging board during movement between the lifted and lowered positions.

A modular, multi-functional, workbench is disclosed that is variable in height, width, and length in order to accommodate a wide variety of applications. The table top includes a plurality of rail pairs supported by leg stands. A rail pair is formed by two extrusions joined together by endplates that maintain a parallel orientation and prevent rotation of the rails. The extrusions are rectangular in cross-section and slotted on all four sides to allow the use of a variety of t-track fasteners. The leg stands support, constrain and locate the rail pairs along the width of the table. The rail pairs provide a table top surface that is generally flat and sturdy. The workbench can be used in an open-grid fashion or with solid top inserts. The modular nature of the workbench makes it easy to store and set up as well as highly versatile and easily transported to job sites.

A truss jigging system has an elongated table forming a support plane and formed with a plurality of parallel slots extending between the two long edges. The table has a plurality of the following: locating pins, carriages, endless belts, idler wheels, and, drive wheels. Each endless belt is strung around a respective one of the idler wheels and a respective one of the drive wheels to form a pair of elongated runs, one run being an elongated return run and the other run having a respective one of the carriages affixed thereto and coursing through a respective slot such that, driving the drive wheel moves the locating pin back and forth along the front to back axis of the respective slot.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

A table comprising a worktop including an axis of rotation, a perimeter, and an effective radius, the effective radius defined as the average distance between the axis of rotation and the perimeter; a frame; a rotational connection disposed between the worktop and the frame, the connection configured to allow the worktop to rotate about the axis of rotation; and a plurality of bearings disposed between the worktop and the frame to rollingly support the worktop on the frame, at least one of the bearings disposed more than half of the effective radius from the axis of rotation.
