A stand (100) is disclosed. The stand (100) may include a first connecting component and a second connecting component. The first connecting component may include at least one fixing element and a chamber. The chamber may have an opening. The second connecting component may include an insertion portion including at least one fixing element and a chamber. The chamber may have an opening. When the insertion portion of the second connecting component is inserted, along an axis in an insertion direction, into the chamber through the opening, the fixing element in the first connecting component may work in pairs with the insertion portion to cause the first connecting component to be connected with the second connecting component.

An apparatus for engaging equipment to a support includes a member defining a first channel having a first side wall capable of lateral movement with respect to a second side wall suitable for engaging the equipment therebetween. The member defines a pair of surfaces suitable for engaging equipment thereon. A movable member is capable of causing the lateral movement. A substantially compressible member is operably interconnected between the movable member and the first side wall. A pin is selectively raisable with respect to one of the surfaces within a peripheral area defined by the one of the surfaces.

A rotation bracket includes an L-shaped connecting rod, a rotation mechanism, and a stand base. The L-shaped connecting rod includes a vertical rod and a horizontal rod. The vertical rod is configured to connect to a communications device. The horizontal rod is fastened to the rotation mechanism, and the horizontal rod is a rotatable rod. The rotation mechanism is fastened to a top of the stand base, and the rotation mechanism is configured to drive the L-shaped connecting rod to rotate in a horizontal plane. The stand base is configured to fixedly connect to an inner surface of a wall or to a ground.

The present invention discloses a mobile device positioning structure including, a central magnetic portion on a mounting surface of a fixture for magnetically positioning the back of a mobile device and a ring-shaped magnetic portion formed by two curved clamp arms which are bilaterally symmetrical to each other, and separated and unfolded from each other. After the two curved clamp arms are unfolded relative to the mounting surface, the back of the mobile device is magnetically positioned by the central magnetic portion, and both sides of the mobile device are elastically abutted, clamped and positioned by the two curved clamp arms.

A carrying device is provided. The carrying device includes a stand, an upper clamp connected to the stand, a lower clamp assembled to the stand, a manipulation mechanism assembled to the stand and interlinked with the lower clamp, and a supporting column assembled to the lower clamp. The manipulation mechanism can drive the lower clamp to move relative to the upper clamp, and the upper clamp and the lower clamp jointly define a receiving space therebetween. The supporting column is movable relative to the lower clamp, so that the carrying device can be adjusted in a first clamping mode or a second clamping mode. When the carrying device is in the first clamping mode, the supporting column is located in the receiving space and faces toward the upper clamp, so that the supporting column and the upper clamp can jointly clamp a plate part of a first structure.

The present invention discloses a display stand has a mounting seat connected on a support structure, internally provided with an accommodating cavity and having a slot communicated with the accommodating cavity at the top in an open way, a supporting arm having an insertion end capable of being inserted into the accommodating cavity of the mounting seat from the slot of the mounting seat, and a locking mechanism disposed on the mounting seat or supporting arm, for locking or unlocking the insertion end of the supporting arm in the accommodating cavity. When the insertion end of the supporting arm is locked, the supporting arm is limited within the accommodating cavity of the mounting seat, and when the insertion end of the supporting arm is unlocked, the insertion end of the supporting arm may be taken out from the slot of the mounting seat.

A wind turbine blade apparatus comprising a root device including: a base having an upper surface with a radius of curvature and configured to receive a root portion of a blade, with housings disposed on lateral sides of the base. The housings including a groove configured to receive a bearing and a shaft extending at least partially through the base and housing. A tip device is also provided which includes a base, a rotatable support frame having: a first support configured to receive a pressure side of a wind turbine blade, a second support configured to receive a suction side of a wind turbine blade, and an opening, the opening configured to receive a portion of a wind turbine blade.

A mounting bracket assembly for an appliance, such as an over-the-range cooking appliance, for mounting to an underside of a wall cabinet, where the cooking appliance includes having at least a rear-facing side and a top-facing side. The assembly includes a wall bracket configured to be secured to the wall near the wall cabinet and configured to support the enclosure on a ledge. The assembly also includes a cam rotatably mounted to the housing to rotatably engage a surface of the ledge to raise the appliance.

A target stand having a base, a vertical beam extending upwardly from the base, a crossbeam, a locking and rotation assembly having a first portion engaged for vertical movement with the vertical beam and a second portion attached to the crossbeam, the first portion attached to the second portion with a pivot bolt, wherein the crossbeam is configured to be disposed in a first locked horizontal position using the locking and rotation assembly, and wherein the crossbeam is rotatable about the pivot bolt to move into a first non-horizontal position.
