A device is configured to be mounted to a planar mounting panel, including, for example, a wall or ceiling of a home or other building. The device includes a housing, a fastener, a dogleg tab and a friction inducing member. The housing is configured to be received in an aperture in the mounting panel and includes a housing aperture. The fastener is disposed in the housing aperture. The dogleg tab is operatively coupled to one end of the fastener. The dogleg tab is configured to be disposed in a retracted position and to be disposed in an engagement position, in which engagement position the dogleg tab is disposed to engage an inside surface of the mounting panel. The friction inducing member is fixedly attached to the housing adjacent the housing aperture and friction-fit to the fastener.

A clamp includes a first clamp body portion arranged for removable coupling about a generally cylindrical support structure to a second clamp body portion. The first clamp body portion includes a first clamp structure containing a first generally semi-spherical floating bushing, the first generally semi-spherical floating bushing coupled to the first clamp structure. The second clamp body portion includes a second clamp structure containing a second generally semi-spherical floating bushing, the second generally semi-spherical floating bushing coupled to the second clamp structure.

Systems and methods directed to a steering column clamp for securing a steering column to a steerer tube are provided. The steering column clamp may include an internal clamp portion having longitudinal slot disposed at least partially between a first end of the internal clamp portion and a second end of the internal clamp portion. The steering column clamp may include a tightening mechanism, when engaged, causes the internal clamp portion to compress about a steerer tube placed in a first end of the internal clamp portion. The steering column claim may also include an exterior wall portion at least partially enclosing the internal clamp portion such that a hollow portion is between the internal clamp portion and an internal surface of the exterior wall portion of the steering column clamp.

The present disclosure provides a quick release and assembly connecting member and a shooting device. The quick release and assembly connecting member includes a connecting cover, a mounting seat, and a fixing mechanism, the connecting cover includes an inserting portion; the mounting seat includes a mounting and locking mechanism; the fixing mechanism is arranged on the connecting cover and/or the mounting seat, and configured for mounting and fixing the quick release and assembly connecting member with a device; the mounting and locking mechanism includes a clamping and locking sleeve and a locking member; the clamping and locking sleeve is configured to enclose a mounting space for mounting the inserting portion; the locking member is capable of switching between a first position and a second position, so that when the inserting portion is mounted in the mounting space, the locking member is capable of locking or unlocking the inserting portion.

A vehicle air vent clamping device is disclosed. The vehicle air vent clamping device includes a base, a supporting arm, a hook for hooking a blade of a vehicle air vent, and an adjustment mechanism for driving the hook to move. The rear end of the supporting arm is connected to the base, and a blocking portion is disposed at the front end of the supporting arm. The hook can be located on the supporting arm in a front-rear movement manner, and when the hook moves to the position of the blocking portion, the hook is hidden in the blocking portion. The adjustment mechanism is connected between the base and the hook.

A mounting device for easy mounting of a wireless device includes a clamping structure configured to clamp a support frame. The clamping structure includes a base including an upper surface and a lower surface, a first clamping part rotatably connected to the base, a second clamping part rotatably connected to the base, and a connection portion connected to the lower surface of the base. The wireless device is thus supported. The support frame is clamped between the upper surface and the first clamping part, and the support frame is clamped between the upper surface and the second clamping part.
