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.

A spring clamp for removably attaching a camera, decoy or other device to a structural support. The clamp includes two opposing arms, each including a handle component and a jaw component. The clamp can be attached to an apparatus when the two jaw components including Inward facing arcuate jaws with gripping teeth and notches are closed around the apparatus. The clamp is provided with a plurality of threaded inserts at selected positions for supporting a device such as a camera. An adjustable and positionable extension may be removably fastened to the camera mount and the camera is detachably coupled to the extension. This allows an article such as a camera to be situated at any desired angle for taking photographs.

A 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, 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 upper and lower combination of the two structures strengthens the swing ability of the top of the pan-tilt in the limited size. The structure is able to be aimed at the subject through the rotating base, and leveled the left and right, and determined the pitch angle.

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 display device comprises: a display module including a display panel; at least one pair of first and second spacers positioned behind the display module and fixed to the display module; and a wall-mountable assembly which is positioned behind the back cover and fastened to the first and second spacers, and which allows the first and second spacers to move. The wall-mountable assembly includes: a fixing part fixed to a stationary object; a frame part having a pair of first and second tilting holes into which the first and second spacers are inserted, respectively, and which guide the movement paths of the first and second spacers; a link part connecting the fixing part and the frame part to each other; and an auxiliary locking part fixed to the fixing part and having at least one magnet attachable to at least a portion of the frame part by magnetic force.

An X-ray detector holder stand maintaining the position of a detector is proposed. A pillar erected on a base has a sliding window formed on the front surface of a pillar housing to extend upwards/downwards. A rack is fixed inside the pillar housing to extend perpendicularly. A wire is wound around multiple pulleys to extend perpendicularly to the front/rear side of the rack. A balance weight is coupled to the wire behind the rack inside the pillar housing. An arm includes a sliding block guided along the sliding window, a stopper gear coupled to the sliding block to rotate between a locking position and an unlocking position, an elastic pressurizing means for pressurizing the stopper gear to rotate to the locking position, and a lever means for rotating/operating the stopper gear to the unlocking position. A holder is coupled to an end portion of the arm to enable rotational manipulation.

The present application discloses an articulating support arm with improved friction joint designs that are facilitated by the use of a non-annular bushing. In particular, the bushing is designed to interact with another portion of the friction joint to prevent rotational movement of the bushing, thereby minimizing the risk of joint malfunction. A bushing that interacts with a larger percentage of the width of a friction cylinder as compared to prior art devices, thereby improving the performance of the joint, is also disclosed. The improved friction joint according to the present invention may comprise an arm joint and/or tilter joint.

An electronic device is provided. The electronic device includes a rotation support member; a support member configured to support the rotation support member; a rotation member movably coupled to the rotation support member; a display movably coupled to a surface of the rotation member; a driving device configured to drive the display; a memory; and a processor, wherein the processor is configured to control, if input information is received, driving of the rotation member to make the display corresponding to the received input information face a first direction, control, if the display moves to face the first direction, driving the rotation member to face a second direction for identify an external object, identifying, if the display is located to face the external object in the second direction, the external object, and display information on at least one function executed in connection with the identified external object on the display.

A camera mount assembly for holding a camera or other perception sensor that may be fixed with respect to a ground plane and used for incremental angle measurement of the camera or other perception sensor in three axes, such that the precise spatial relationships of imaged objects with respect to the orientation/position of the camera or other perception sensor may be determined. A base structure of the camera mount assembly may be affixed to a fixed or moveable support structure and multiple leveling devices and/or laser devices are provided to establish a reliable reference relative to the ground plane. Thus, the exact orientation of the camera or other perception sensor in space may be determined frame to frame, such that the precise orientation of imaged objects with respect to the orientation/position of the camera or other perception sensor relative to the ground plane may be determined over time.

A laser level assembly including a mounting bracket and a laser level. The mounting bracket includes a mounting portion and a base portion transverse to the mounting portion. The laser level assembly also includes a first motor that drives vertical translation of the laser level relative to the mounting portion of the mounting bracket. The laser level assembly also includes a second motor configured to drive rotational motion of the laser level about a vertical axis.
