1. A release mechanism for a toilet lid, comprising:
a shell, including a notch formed on the top of said shell; a fixed block, including a U-shaped recess corresponding to the notch on said shell and formed on a top end of the fixed block, a continuous U-shaped groove formed on a bottom surface and two sides of the U-shaped recess; a U-shaped clamping spring installed inside the U-shaped groove and configured to engage with the U-shaped groove; and a rotating shaft comprising a tail portion, a central portion, and a head portion; wherein said rotating shaft is configured to rest in the U-shaped recess on the fixed block, the tail portion of said rotating shaft extending out of the fixed block, the central portion and the head portion of said rotating shaft positioned in the U-shaped recess, an end surface of the head portion of the rotating shaft attaching to a side of the U-shaped recess, and the U-shaped clamping spring clamping the central portion of said rotating shaft; wherein said rotating shaft is in the shape of a screw, the tail portion and central portion of the rotating shaft forming a column structure, the head portion of the rotating shaft coaxial with the tail and central portions and forming the head portion of the screw shape; wherein the tail portion of the rotating shaft is formed by beveling two sides of a front portion of a cylinder, the un-beveled portion forming the central portion of said rotating shaft, and the head portion is formed by tangentially beveling two sides of a cylinder, the beveled surface of the head portion being parallel to the beveled surface of the tail portion of the rotating shaft; wherein a diameter of the head portion of the rotating shaft is greater than diameters of the tail portion and the central portion of the rotating shaft, such that the tail portion and the central portion of said rotating shaft form a step structure with the head portion of the rotating shaft, respectively; wherein the bottom surface of the U-shaped recess of said fixed block is a curved surface and is a stepped surface from an edge of the fixed block to an innermost portion of the fixed block.
