发明名称 Apparatus for holding and positioning a measuring tape
摘要 The holder of the present invention is comprised of a clamp for receiving and securing a measuring tape with its zero end being located at a known position. The clamp is pivotally joined to a base which contains a magnet for attaching the base to a ferro-magnetic surface. The apparatus is attached to the surface by positioning the base in a manner such that the zero end of the tape is located at a first meausring point. The tape is then extended by the user to measure the distance from the first measuring point to a second measuring point, which is remote from it, without the necessity of having a second person to hold the zero end of the tape.
