Abstract: Hanging hook structure including a hook body, two casings mated with each other, a press rod, a compression spring and a restoring spring. A slide stem downward extends from lower side of the hook body and is formed with a plane attaching face on one side. An upper rear side of the slide stem is formed with an escape recess. A stop block is formed under the escape recess. A front side of the slide stem is formed with an insertion notch. A lower end of the slide stem is formed with a restoring spring pushing cavity under the insertion notch. An inner side of each casing is cut with a slide channel and a push channel to form a cross shape. An upper end of one side of the slide channel is provided with a projecting stop block (or a dent). A lower end of the slide channel is formed with a restoring spring retaining section. A front section of the push channel is formed with a compression spring retaining section.

The hook section has a stem body a lower end of which is formed with an annular stop section. One side of the stop section is cut with a restricting split. The other side of the stop section is provided with a downward extending hook. An upper end of the stem body is pivotally connected with the ring body. An upper side of the latch member is formed with a receiving hole. A bottom face of the receiving hole is formed with a through hole. One side of the latch member is formed with a downward extending latch arm. A lower side of the restricting column is provided with a small diameter fitting post. A stop face is defined between the small diameter section and the large diameter section of the restricting column. The restricting column is formed with a central passage.
