The present invention relates to the technical field of photography and videography, in particular to a gear fine-tuning pan-tilt. The gear fine-tuning pan-tilt includes a rotating base, a roll worm support seat, a roll adjusting assembly, a pitch adjusting assembly, and a bearing seat arranged in sequence from bottom to top; the pitch adjusting assembly of the complete gear structure is located on the above, providing large-angle pitch ability, and the roll adjusting assembly located below adopts an arc-shaped rack structure, which reduces the interference to the pitching movement of the upper assembly and makes the height of the pan-tilt smaller. The arc opening of the arc-shaped rack faces upwards, so that the rotation axis is closer to the center axis of the lens, the camera displacement is small during the leveling process, and the unintended picture movement is small. The upper and lower combination of the two structures strengthens the swing ability of the top of the pan-tilt in the limited size, and is therefore more convenient to use: firstly aiming at the subject through the rotating base, and then leveling the left and right, and then determining the pitch angle. The camera always maintains the left and right level during pitching process. There is no need to level the left and right again after the pitch angle is changed, and roll deviation will not occur when the camera pitches and the lens is moved.

The present application disclosed a pan-tilt structure and a lighting device, and the pan-tilt structure includes a base, a ball, a ball sleeve, and a locking mechanism, a side of the base is provided with a support surface; the ball is arranged on the support surface; the ball sleeve includes a locking member connected to the base, the locking member is arranged around the ball, and the locking member is provided with a first locking portion and a second locking portion that are arranged in an extending direction along the locking member, and an adjustment gap is provided between the first locking portion and the second locking portion and configured for disconnecting the locking member; an adjustment assembly of the locking mechanism is connected to the first locking portion and the second locking portion.

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.

An apparatus (10) for holding and supporting articles including support means (20) having receiving means (25, 26, 27), one or more elongate members (30, 32, 34) each having a first end adapted to fit into said receiving means (25, 26, 27) of the support means (20), connector means (40) adapted to fit to a second end of any one or more elongate members (30, 32, 34) for releasably engaging a respective article.

A mounting member for mounting a mobile device and a mobile device accessory of being fixed to one face of the mobile device and having a ring on an object, the mounting member includes a body, a slot portion being formed in a part of the body and having a receiving groove for receiving the ring and a pressing portion disposed inside the receiving groove and configured to elastically press the ring to be located in the receiving groove.

Mounting apparatus is used for supporting an accessory device, e.g., a sensor, in a manner permitting adjustment. An accessory device-receiving mount is fixable to the accessory device and has at least one surface forming a cross-section permitting adjustment in at least one degree of freedom. A clamp ring engages the device-receiving mount at the surface, so that the cross-section permitting adjustment. A clamping mechanism selectively clamps the clamp ring and includes a manually threaded fastener and a lever-operated clamp tightener. The lever-operated clamp tightener acts on the manually threaded fastener to releasably tighten the clamping mechanism beyond that achieved by manually threading the manually threaded fastener, permitting manually threading the clamping arrangement at a maximum tension less than a full tension applied by the lever-operated clamp tightener.

A clamp sleeve, including: a body and a first fastening assembly. The body has first and second ends, and includes a receiving portion therein. The receiving portion has first and second openings at the first and second ends. The body is provided with a gap, the gap has two ends extending to the first and second openings, and the gap is communicated with the receiving portion. The body is provided with first extending portions at two sides of the gap along a longitudinal direction, the first extending portions is provided with a first connecting sheet near the first opening, and the first connecting sheet is connected to each of the first extending portions and connected with the first opening. The first connecting sheet is provided with a first thin thread intersecting with the gap. The first fastening assembly is disposed on the first extending portions.

Adjustment of a posture of a ball joint is facilitated. A support device includes a pan head unit, a ball joint having a first end to which the pan head unit is attached and a second end provided with a ball portion, a ball holder configured to selectively fix the ball portion, a ball fixing screw connected to the ball holder and configured to move the ball holder between a locked position at which the ball portion is fixed and an unlocked position at which the ball portion is freely rotatable, and an elastic member configured to urge the ball holder toward the ball portion. The ball holder and the ball fixing screw are connected to each other so as to be strokable with a predetermined stroke amount. The predetermined stroke amount is smaller than a movement amount of the ball fixing screw between a first position corresponding to the locked position and a second position corresponding to the unlocked position.

A triaxial spherical universal joint structure includes: a body; a sphere; and a rotating shaft, wherein the body is provided with a sphere accommodating part and a rotating shaft accommodating part adjacent to each other in up-and-down directions, the sphere accommodating part extends upward to form an opening of the sphere accommodating part, the rotating shaft accommodating part extends downward to form an opening of the rotating shaft accommodating part, the body is provided with a notch extending from the opening of the sphere accommodating part to the opening of the rotating shaft accommodating part, the sphere accommodating part and the rotating shaft accommodating part are communicated with the external space via the notch, a fixing assembly is provided on the body at a position close to the notch and the opening of the sphere accommodating part, the rotating shaft may rotate horizontally in the rotating shaft accommodating part.

Disclosed is a display stand, including a moving unit configured to extend in a direction perpendicular to a first link configured to extend from one side of a monitor fixing unit, and an elevating unit including a housing configured to have an elevating hole formed therein so that the moving unit is inserted into the elevating unit therethrough, a support member installed in the housing so that the moving unit is movable in a lengthwise direction of the housing and configured to extend in a direction perpendicular to a floor surface, and friction units configured to surround the support member, to have one surface coupled to the moving unit and a plurality of friction members, and to come into contact with an inner surface of the housing.
