Abstract
A quick-release hook comprising a latching hook locker, a spring, a pair of latching hooks, a pull lever and a main body. One end of the latching hook locker is shaped into a cylinder and the other end is shaped into a frustum. The latching hook locker also has a groove slot on the side of the cylinder section close to the frustum. The spring is fastened to the cylindrical end of the latching hook locker. The two latching hooks each has a U-shaped profile and is in contact with the frustum of the latching hook locker. One end of the pull lever has a protruding section for inserting into the groove slot of the latching hook locker. The main body encloses the latching hook locker, the spring, the pull lever and the two latching hooks but exposes a portion of the two latching hooks and a portion of the pull lever. The pull lever has a protruding section that links up with the main body. The other end of the pull lever remains outside the main body and is free to rotate in an arc. One end of each latching hook is enclosed and attached to the main body. The other end of the latching hook remains outside the main body and is free to rotate in an arc.
