A wind turbine blade handling apparatus for rotating and lifting a blade. The apparatus includes a root device having a root support member with a concave upper surface and rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; a base, and a scissor-lift mechanism with intersecting struts which converts from a lowered position wherein the struts are disposed in a generally coplanar configuration, to an elevated position wherein the struts are disposed in an angled configuration.

A swivel mechanism (200) for orientating a camera includes a base (8) configured to attach to a support structure; a wedge mechanism comprising a first wedge (5) and a second wedge (6) each having an inclined surface (5d, 6b) on one side, wherein the inclined surface of the first wedge (5d) is arranged on the inclined surface of the second wedge (6b), a back cover (1) configured to receive a camera head (100), the back cover (1) arranged at a side of the swivel mechanism (200) opposite to the base (8) in a direction of a pan axis (A1), wherein the back cover (1) comprises a joint member (1a) connected to the wedge mechanism; a housing (40), arranged in the direction of the pan axis (A1) between the base (8) and the back cover (1), wherein the housing (40) encloses the joint member (1a) and the wedge mechanism.

An adjustable mounting apparatus for electronic devices is configured to be adaptable to various support structures, and to facilitate a customized mount orientation for the electronic devices through several degrees of pivot freedom. The mounting apparatus is particularly adaptable to outdoor or industrial environments in which standard support structure modalities may not be available.

Disclosed is a display stand including a first rotational coupling unit, and the first rotational coupling unit includes a coupling member installed in a central part of a first link and configured to pass through the first link and a second link so as to allow the first link and the second link to be rotatable in leftward and rightward directions, metal bushes installed on an outer surface of the coupling member so as to surround the coupling member and inserted into the first link so as to press the first link, and first toothed lock washers installed on the outer surface of the coupling member so as to surround the coupling member, disposed on outer surfaces of the metal bushes, and configured to have connection members provided towards an inner surface of the first link so as to be pressed against an inner surface of the second link.

Support systems and stands for electronic devices include tilt hinges, lift arms, and their component parts. Some tilt hinges include assemblies for guiding and retaining bars or protrusions into preferred positioning within receiver openings to unify the parts, particularly as they move, and to reduce wobble or slop in the joints. Lift arms provide simplified and low-cost guidance and counterbalance mechanisms for controlling movement of the electronic device relative to the base of a stand. In some cases, the lift arms have sheaths to help protect or cover mechanisms while allowing additional space for the mechanisms within the lift arm. Other interconnection systems hide and protect a connector interface between the stand and the electronic device within a housing until unlocked and the connector is moved into an exposed position. These systems improve efficiency, comfort, ergonomics, accessibility, and user satisfaction of the electronic devices and their supports.

An angle-adjustable supporting mechanism that includes a knob-type locking mechanism and a rotatable holder is provided. The knob-type locking mechanism has a base, a knob, and a latch member. The base has a receiving space and a supporting portion. The knob is rotatably received in the receiving space. The latch member is movably received in the supporting portion in a linear direction. The latch member has a bolt, a first stressed part, and a second stressed part. The bolt is disposed at one side of the first stressed part. The first stressed part is disposed between the bolt and the second stressed part. When the knob is rotated in different directions, the bolt of the latch member is drove to lock or release.

A coupling for swivably coupling an arm to a post, the coupling in use cooperating with the post as an engaged element via a post interface, and with the arm as an engaged element via an arm interface, wherein the coupling including its interfaces provides limited relative rotational movement between the arm and the post about a swivel axis extending along a longitudinal axis of the post, wherein the limited rotational movement is provided in a rotational zone that corresponds to a single revolution about the longitudinal axis. The disclosure further relates to a coupling system, and to a monitor support.

An angle adjustment apparatus is provided, and includes a fastening component and an angle adjustment component rotatably connected to the fastening component. At least a part of the angle adjustment component is located in the fastening component, and the angle adjustment component can rotate in a horizontal direction and a vertical direction relative to the fastening component. In this way, angle adjustment efficiency is improved. In addition, a communication device can be prevented from being oblique after angle adjustment, thereby preventing a signal coverage function of the communication device from being affected.

A wall-mounted holder is used to fix a photographic equipment to a wall. The wall-mounted holder includes a seat, a cover, and a connecting member. The seat is fixed to the wall. The cover is engaged with the seat in a manner that allows the cover to be movable along an axis relative to the seat. The connecting member has a ball joint that is clamped between the cover and the seat. The connecting member has a shaft that is connected to the ball joint. A part of the shaft protrudes out of the cover, so that the photographic equipment could be mounted to the shaft. Thus, by adjusting the swinging position of the shaft, a camera shot angle of the photographic equipment could be changed.

A selectively adjustable and lockable utility mount is used to mount a device to a stable structure. The utility mount includes a hydraulic lock that applies the locking force that maintains the locked condition of the utility mount. Mounting brackets for utility mounts have spaced-apart mount elements that engage a surface of a stable structure. Some configurations of mounting bracket include mount elements that are movable between stored conditions and deployed conditions. The stored conditions reduce the size of the device to make it more convenient to pack. A climbing stick uses the storable mount elements.
