<p>PURPOSE:To easily install a variety of desired water supply cocks by revolving a tightening piece screwed onto the upper surface of a body seat part and closely attaching the water supply cock with a water supply faucet by providing a necessary pressing force by increasing the outside diameter of an installation body installed on the outside of a screw. CONSTITUTION:A screw 3 is formed on the lower side of the seat part 2 of a body 1, and screwed with the screw 16 of a hose metal fitting 17 for connection. Then, a screw 5 is formed on the lower side of the seat part 8 of a tightening piece 4, and screwed with a screw part 6 formed at the center of the upper surface of the seat part 2 of the body 1. An installation body 10 consisting of an elastic body made of rubber is fitted onto the outside of the screw 5, and interposed between the seat part 4 of the tightening piece 4 and the seat part 2 of the body 1 through a seat metal 9. The tightening piece 4 is fitted into a water supply faucet 12, and the tightening piece 4 is revolved to press the installation body 10, which is allowed to contact the inside diameter side 13 of the water supply faucet 12 by increasing the outside diameter of the installation body 10, and tightened to provide a necessary pressing pressure, and then close attaching and fixation are carried out.</p> |
