A clamping device for mounting a mobile terminal device to a hot shoe of an image photographing apparatus includes a quick release structure and a clamping assembly. The quick release structure includes a cold shoe fixing piece for connecting to a quick release interface of the hot shoe, and a first locking structure for selectively quickly locking the cold shoe fixing piece to the hot shoe, or quickly unlocking the cold shoe fixing piece from the hot shoe. The clamping assembly is configured to clamp the mobile terminal device, so that the mobile terminal device can be mounted, together with the quick release structure, to a quick release interface of the image photographing apparatus along with the clamping device. This facilitates quick and reliable mounting of the mobile terminal device to the image photographing apparatus, and quick removal of the mobile terminal device from the image photographing apparatus.

A gimbal device according to various embodiments of the present disclosure may include: a handle; a gimbal; a joint pivotably coupling one end of the gimbal to the handle; and at least one processor, wherein the gimbal includes: a holder configured to hold an electronic device including a camera; an angular velocity sensor disposed in the holder and configured to detect a movement of the holder; and a plurality of motors coupled to the holder and configured to pivot the holder in pitch, roll, and yaw directions according to the detected movement. The at least one processor is configured to identify a pivoting state of the joint, and to change axis information assigned to each of detection values of three axes obtained by using the angular velocity sensor, based on the identified pivoting state. Other embodiments are possible.

A rotationally limited connection system that includes a first mount to hold an object or couple with an object, a first ferromagnetic coupling element that includes a material attracted to a magnet or wherein the material includes the magnet, an a first mechanical coupling element. The first mechanical coupling element includes at least one protrusion to limit rotation of the first mount with respect to another object in 90 degrees increments. The first mount is coupled with the first ferromagnetic coupling element and the first mechanical coupling element.

The support device has a mount part 10 for mounting an electronic device, a pair of support leg parts 20, and a pair of cross brace parts 30. The electronic device 600 when mounted on the mount part 10 is supported so as to be slanted rearward. The two support leg parts of the pair of support leg parts 20 are each provided with multiple receiving seats capable of receiving an anchor part of a cross brace part 30 and multiple bowl-shaped hole parts corresponding to the multiple receiving seats. The two cross brace parts of the pair of the cross brace parts 30 are each provided with a biasing stud having a semispherical tip, and when an anchor part is received by any of the receiving seats of the pair of support leg parts 20, the stud enters the bowl-shaped hole part corresponding to the receiving seat. Furthermore, the two cross brace parts of the pair of cross brace parts 30 maintain the angle of the pair of support leg parts 20 with respect to the mount part once the biasing studs have entered the bowl-shaped hole parts as the anchor parts are received by the receiving seats, and the biasing studs in the bowl-shaped hole parts are pulled out as the anchor parts detach from the receiving seats 201 and slide on inner surfaces of the pair of support leg parts 20 when the support leg parts are turned with respect to the pair of cross brace parts 30.

A holder for holding a mobile electronic device to an object, the holder having two first openings, a first communication path, two second openings, and a second communication path. The two first openings form a first set of openings. The first communication path connects the first openings so a securing device can be fed into one of the first openings and out of the other of the first openings. The two second openings form a second set of openings. The second communication path connects the second openings so that the securing device can be fed into one of the second openings and out of the other of the second openings. The first openings are spaced apart from the second openings so the securing device can be secured to the holder at the first and second sets of openings, and additionally wrapped around the object to secure the holder thereto.

An adapter for releasably fastening a portable/compact unit or object to a holding device. The adapter comprises a base plate and two projections projecting away from one another in opposite directions and at a spacing from the base plate. The base plate has means for attaching the adapter to the unit or object or attached fixedly thereto or is configured in one piece with it. A guide disc is mounted on the base plate, is parallel to said base plate and can be rotated at least to a limited extent between at least one released position and at least one locked position. The guide disc has a middle opening, into which the two projections extend. The opening comprises two plug-in regions into which a holding device suitable for interaction with the adapter can be plugged in at least partially when the guide disc is situated in a released position.
