A magnetic clamping apparatus includes a magnetic base, a handle, a grip, and a central axis. The magnetic base includes a magnet body and a mounting body. The handle and the magnetic base are concentrically positioned around the central axis. The mounting body is concentrically connected onto the magnet body thus allowing the magnet body to attach ferrous metals. The handle is terminally connected to the mounting body, and the grip is connected around the handle so that the user can easily grasp and control the magnetic clamping apparatus.

A chuck structure includes: a first chuck, provided with a seat slidable relatively thereto, the seat provided with a first stop; a limiting element, swingable relatively to the seat, and provided with a second chuck; and an operating element, respectively connected with the limiting element and a second chuck, and driving the second chuck to move relatively to the first chuck to form an accommodation space between the first chuck and second chuck, an elastic element configured between the operating element and limiting element, and the elastic element pressing against the limiting element to approach the seat, allowing the second and first stops to be in contact with each other. The present invention can use the operating element 3 to adjust the size of the accommodation space, and the second stop in contact with first stop to make the operating element can only be rotated in a single direction.

A method of creating a shear across a fastener for a tool collet being attached to a hand tool includes providing a tool collet having a collet body with a peripheral body surface and a collet through opening where the collet body is divided into a first body component and a second body component attachable to each other and where one of the first body component and the second body component has a first radial through aperture extending from the peripheral body surface to the collet through opening, providing a setscrew within the first radial through aperture, inserting a hand tool into the collet through opening, securing the first body component to the second body component, and tightening the setscrew against the hand tool sufficient to cause the first body component and the second body component to slide in opposite directions transversely to the portion of the hand tool.

The application is directed to a device for assisting individuals with the installation of one or more construction materials. The device is operationally configured to support construction materials at an elevated position. The device is also operationally configured to be attached to horizontal surfaces, vertical surfaces and angled surfaces.
