  • Fastening device - tool holder
    Patent number: 5400844
    Abstract: The tool holder is designed to hold an object rigidly in place, at a strategic location, with the benefits of simplicity of placement and easy removal. There are two basic parts: base assembly and the tool mount assembly that mates with it. A spring loaded, cam activated piston locks the pieces together. A non-locking internal conical taper permits 360 degree rotation. A handle mounted on the side activates the camming mechanism to lock the tool or object rigidly in place, being secured to the tool mounting surface.
