Abstract
An interlocking rotatable assembly includes multiple interlocking pieces. Each of the interlocking pieces has a disk, a center hole formed through a center of the disk, a mounting slit radially formed in a peripheral edge of the disk, two arms, and two engaging protrusions. The arms parallelly protrude from the peripheral edge of the disk and are oppositely disposed beside the mounting slit. The engaging protrusions protrude from the arms respectively. No undercut is formed on each of the interlocking pieces. Therefore, only a female die and a male die are needed when manufacturing the interlocking pieces by injection molding process. Molds and manufacturing process for manufacturing the interlocking piece are simplified. Accordingly, mold cost and manufacturing cost of the interlocking piece are reduced, and defect-free rate of the interlocking piece can be increased.
