Abstract
A multi-stage positioning rotary disk includes an inner disk and an outer disk hinged on the inner disk and turnable thereon. The inner disk has at least one latch cavity to hold a latch member elastically extended outwards from the latch cavity. The outer disk has a plurality of positioning slots latched with the latch member. Each positioning slot is formed from a greater depth to a smaller depth according to turning direction of the outer disk. Hence the latch member is latched sequentially on the positioning slots during relative turning between the outer disk and inner disk to allow the outer disk to provide staged positioning function. The structure is simpler and staged positioning is easy to operate when in use, and durability is enhanced and production cost is lower.
