Abstract: A drain plug linkage device comprising; a pull rod assembly including a pull rod and pull rod connector, a link rod having adjustment teeth and square spaces between them along its height, and a lever member having adjustment holes along its length. The link rod and lever member are connected through an adjustment mechanism which contains a push button lever adjustment mechanism by which a specific adjustment hole can be selected and locked into place, and a push button link rod adjustment mechanism by which a specific by space between the teeth may be selected and locked into place, whereby a user can easily select both the effective length of the lever member and the effective height of the link rod following installation of the drain plug linkage device and thereby optimize efficient operation of the linkage device.

Abstract: A quick installation and release nut for a faucet includes a main body, a receiving assembly on the upper portion of the main body, a press plate which is movably disposed on the receiving assembly, and at least two movable lock blocks disposed in the receiving assembly, is disclosed. The press plate comprises at least one vertically oriented diagonal slide for each of the movable lock blocks. The at least two movable lock blocks comprise an inner wall having internal threads corresponding to the threads of a threaded rod, and an outer wall having vertically oriented diagonal slide grooves for slidably receiving the vertically oriented diagonal slides of the press plate. When the press plate is depressed, the diagonal slides of the press plate, in conjunction with the diagonal grooves in the lock blocks cause the lock blocks to move inwardly towards the axis of the threaded rod until the lock blocks engage the external threads of the threaded rod.
