Abstract: An adjustable water pipe includes a connecting block, a conduit, a securing sleeve, and a metal wire. The conduit is flexible, and is firmly joined to the connecting block at a first end. The connecting block has a through hole and an outlet communicating with an inner space of the conduit. The securing sleeve is provided to press the first end of the conduit tightly against the block, preventing water from leaking through the joint. The metal wire has plasticity so that it can be bent into various shapes. The metal wire is placed along the inner space of the external conduit, and is firmly inserted into one end of the through hole of the connecting block, helping the conduit stay bent in conveying water after adjustment of position.

Abstract: A stop valve for water pipes includes a body, and a valve block. The body has a through hole extending from one end to other, and a cylindrical holding hole on one side to communicate with the through hole. The valve block has a transverse hole, and is disposed in the cylindrical holding hole so that water can flow through the through hole when the valve block is open where the transverse hole is aligned with the through hole of the body. In addition, the valve block is formed with a cylindrical shape so that it can be stably held in position by means of those portions of the body that define the cylindrical holding hole to secure a tight contact of the valve block with a leak-prevention ring equipped around one inner end of the through hole.

Abstract: An extensible cleaner rod includes an outer tube and an inner tube telescoped in the outer tube, and then a water guide tube of a smaller diameter than that of the inner tube is provided in the outer tube. Then the volume of water flowing through the cleaner rod is always definite, no matter how large the outer tube and the inner tube may be. So the extensible cleaner rod may be used easily not adding a large weight to the whole cleaner rod even by enlarging the diameter of the outer tube and the inner tube for strengthen it.
