A bracket for connecting a stair rail to a post comprises a base and a cover adapted to slide over the base. The base comprises a plate and two opposed sidewalls. The plate has first and second surfaces. The sidewalls extend from the first surface of the plate. Two plate protrusions are formed on the second surface of the plate, with the two plate protrusions extending for at least a portion of a height of the plate. The cover comprises a roof, two opposed cover walls extending from the roof, and two flanges. Each of the cover walls comprise a cover wall edge, with each of the flanges extend from the cover wall edge for at least a portion of a height of the cover wall. The flanges are adapted to engage with the plate protrusions when the cover is slid over the base.

A fitting assembly can include a socket fitting comprising an end wall and a substantially cylindrical sidewall extending from the end wall, the end wall and cylindrical sidewall defining a cylindrical interior recess, the cylindrical sidewall defining an open end opposite the end wall allowing access to the cylindrical interior recess, the cylindrical interior recess configured to receive a first end portion of a brace member, a bore formed through the end wall and a hole formed through the cylindrical sidewall; a first fastener engaged with the hole and extending into the cylindrical interior recess, the first fastener configured to couple the brace member to the socket fitting; and a second fastener defining a tail end engaged with the bore, the second fastener repositionable relative to the socket fitting to adjust a length of the fitting assembly, wherein the second fastener is oriented perpendicular to the first fastener.

A connection assembly for robot joints, including: a first joint provided with a first connection end, where a connection base is provided on the first connection end, and the connection base is provided with a first connection protrusion extending radially outward; a second joint provided with a second connection end, where a connector is provided on the second connection end, and an external thread is provided on an outer circumference of the connector; and a connection nut adapted to be rotatably sleeved on the connector, where an internal thread is provided on an inner circumference of the connection nut, a second connection protrusion extending radially inward is formed at an end of the connection nut facing the first connection end, and the second connection protrusion is sleeved on a radial outer side of the connection base, such that the first connection protrusion is accommodated in a space, facing the second joint, formed by the second connection protrusion. The problem of complicated assembly and disassembly of joints of a collaborative robot is solved.

A universal hub adapter for a portable display frame assembly, the hub adapter being configured to mount to an outer surface of a display hub of the frame assembly. The universal hub adapter is configured to adapt the display hub of the frame assembly between the mounting of a first graphics system including a plurality of stretched fabric panels and a second graphics system including a channeled sub-frame for mounting a larger fabric panel. The universal hub adapter can include a faceplate having a substantially planar outer surface and a concave inner surface configured to mate with the convex outer surface of the display hub and a threaded post having a threaded portion, a securement plate, a button shaft, and a button head, the threaded portion configured to pass through an aperture of the faceplate and couple to the display hub, such that the securement plate abuts up against the faceplate thereby securing the faceplate to the display hub, the button shaft and button head configured to operably couple to one of a stretched fabric panel or a sub-frame assembly.

A microphone holder includes a coupling seat and a holding seat having a lower end coupled to the coupling seat. The holding seat includes an adjusting portion above the lower end of the holding seat and a clamping portion located above the adjusting portion. A longitudinal groove extends from a top end of the adjusting portion and is defined by first and second actuating portions having first and second inclined guiding portions, respectively. The clamping portion includes first and second clamping pieces having lower ends connected to the first and second actuating portions, respectively. A clamping groove is defined between the first and second clamping pieces. An adjusting ring is disposed around the adjusting portion and includes a longitudinal hole. An upper end of the inner periphery of the longitudinal hole includes an abutting portion configured to abut against the first and second inclined guiding faces.

A lockable relative rotation device can comprise a first body including an outwardly extending inner flange having a first side, and a first interface feature associated with the first side of the inner flange. The lockable relative rotation device can also comprise a second body operable to rotate relative to the first body about an axis and to translate relative to the first body in first and second directions parallel to the axis. The second body can include an inwardly extending outer flange disposed proximate the first side of the inner flange, and a second interface feature associated with the outer flange. The first and second interface features can be operable to selectively engage and disengage one another upon relative translation of the first and second bodies in the first and second directions, respectively. When the first and second interface features are engaged, the first and second bodies can be maintained in a fixed rotational relationship with one another about the axis and, when the first and second interface features are disengaged, the first and second bodies can be free to rotate relative to one another about the axis. Additionally, the lockable relative rotation device can comprise a locking mechanism associated with the first body. The locking mechanism can have a barrier selectively movable in the first direction to maintain engagement of the first and second interface features, and movable in the second direction to facilitate disengagement of the first and second interface features.
