The present invention discloses a foldable mechanism and an infant carrier thereof. The foldable mechanism includes a first mount, a second mount and a locking member movably disposed between the first mount and the second mount. The first mount is pivotally connected to the second mount. The infant carrier is locked in the folded state when the first mount rotates to a first rotating position relative to the second mount. The infant carrier is locked in the expanded state when the first mount rotates to a second rotating position relative to the second mount. The first mount is locked at the first rotating position or the second rotating position via movement of the locking member, so as to make the foldable mechanism have a simple folding mechanical design and improve folding stability of the foldable mechanism.

A tool holder comprises a cage assembly having a pair of axially spaced hollow members with axially aligned through openings sized for axial extension of tool handles of different sizes and shapes through both of the aligned openings. A cradle member is transversely movable in opposite directions between the hollow members toward and away from respective inwardly facing wall surfaces of the hollow members for releasably clamping tool handles extending through both aligned openings against the inwardly facing wall surfaces.

A foldable mechanism is applied to locking an infant carrier and includes first and second mounts and a locking member. The second mount is pivoted to the first mount and has first and second mating portions. The infant carrier is locked in the folded state when the first mount rotates to a first rotating position, and is locked in the expanded state when the first mount rotates to a second rotating position. The locking member is movably disposed between the first and second mounts and has a positioning portion and a locking portion. The positioning portion is engaged with the first mating portion to lock the first mount at the first rotating position. The locking portion is engaged with the second mating portion to lock the first mount at the second rotating position. A depth of the first mating portion is shallower than a depth of the second mating portion.

A rotational coupler in one aspect of the present disclosure includes a plate-shaped first member, a plate-shaped second member, a tapered portion, and an outer circumferential ring. The outer circumferential ring includes a first ring flange configured to externally come into contact with the first member. The outer circumferential ring includes a bent portion in a middle part of the second ring flange in an extending direction. The bent portion is bent to protrude toward the first plate of the first member.
