A gate apparatus that includes a gate, an elongate member or gate base for the ends of the gate, and a stairway post adapter such that a wooden stairway post can serve as a base for a gate without harming the wood of the stairway post. The stairway post adapter includes a vertical or longitudinally running channel for receiving the gate base, a horizontally or laterally extending channel for receiving a strap, and a recess or receptor or face for confronting a section of a stairway post. The gate base includes an upper and lower eyelet. Each of the ends of the gate includes upper and lower pins for engaging the upper and lower eyelets of the gate bases. On the hinge side of the gate, the pins are relatively long and remain in the eyelets as the gate is lifted and swung. On the latch side of the gate, the pins are relatively short such that that latch side of the gate can be lifted and disengaged from the eyelets and then swung open. The gate is extendable and retractable in length, and is reversible.

Disclosed is a locking device, comprising an outer sleeve (1) and at least one locking unit (2) located in the outer sleeve (1), wherein the locking unit (2) is formed by connecting a plurality of pressing blocks (3), a gap (5) is provided between two adjacent ones of pressing blocks (3), a rod locking hole (6) is provided in the gap (5), and a set screw hole (7) is provided on the outer sleeve (1) at a position corresponding to the locking unit (2); and when a set screw is screwed into the set screw hole (7) to directly or indirectly press the locking unit (2), the locking unit (2) deforms and drives the pressing blocks (3) to tightly press rods (8, 9) mounted in the respective rod locking holes (6) at the same time.
