<p>PURPOSE:To facilitate fitting work at a high place, by fitting a headless bolt spirally on the screw hole of a flat plate section connected to a circular rod, and by tightening fitting pieces for fitting the hexagonal section of an anchor clamp on both the sides of the flat plate section, with the flat plate section and nuts. CONSTITUTION:At the tip of a circular rod section 1b constituting a holding rod 1, a flat plate section 1a is integrally formed. On the flat plate section 1a, a screw hole is set and a headless bolt 2 is spirally fitted, and on the one side surface of the flat plate section 1a, a projected section 1c is set. A fitting piece 3 consisting of a plane section 3a having a hole on the center, and a curved section 3b having a triangular slit inside, and a fitting piece 4 with the same mechanism are butted to both the sides of the flat plate section 1a, and are tightened with nuts 5 and 6. Then, the hexagonal section of a clamp is easily tightened and it is suitable for work at a high place. The fitting pieces are have a symmetrical form, and the production and management are rationalized.</p> |
