Abstract

A quick-release assembly, a photography kit, and a quick-release rotary support. The quick-release assembly comprises a rotating shaft (11) and a locking assembly (20) used to clamp the rotating shaft (11). The locking assembly (20) comprises rotating members (23, 24), at least one clamping member (21) and at least one elastic member (22), wherein the elastic member (22) is used to push the clamping member (21) to clamp an outer peripheral surface of the rotating shaft (11). The rotating members (23, 24) rotate to drive the clamping member (21) to release the rotating shaft (11). The quick-release assembly achieves the locking of the rotating shaft (11) by using the elastic member (22) to exert an acting force on the clamping member (21) to clamp the rotating shaft (11), and the rotating shaft (11) is released by means of actuating the rotating members (23, 24) to drive the clamping member (21). Upon the release of the rotating members (23, 24), the elastic member (22) drives the clamping member (21) to reset so as to clamp the rotating shaft (11) again, thereby locking or unlocking the rotating shaft (11). Thus, an angle of a first external connecting assembly connected to the rotating shaft (11) can be adjusted. If the first external connecting assembly can be mounted with a photographing device, a photographing angle of the photographing device can be adjusted. The quick-release assembly is simple and quick to operate.

When the rotating shaft 11 needs to be unlocked, the unlocking portion 251 slides along the inclined surface of the first lug portion 233 and the second lug portion 243 facing each other when the hand-held portion 252 is pulled outward to drive the sliding portion to slide, so that the first lug portion 233 and the second lug portion 243 rotate in opposite directions. When the first lug portion 233 rotates to drive the first annular portion 232 to rotate, a first limiting portion 231 pushes a clamping member 21 to slide. When the second lug portion 243 rotates to drive the second annular portion 242 to rotate, a second limiting portion 241 pushes another clamping member 21 to slide.

The locking control of the clamping assembly 10 and the locking assembly 20 can be performed separately without affecting each other. The number of the clamping jaws 14 is set according to personal use requirements, such as three or four, and the intervals can be the same or different.

Its kinematic pair is similar to the threaded pair form of threaded connection, and the spiral teeth formed by the thread line and the fixed teeth on the clamping jaw 14 constitute a structure similar to the threaded pair.

When the threaded disk 13 rotates forward, the thread line on the threaded disk 13 and the fixed teeth on the clamping jaw 14 move relative to each other. Under the restriction of the limiting groove 121 on the fixing seat 12, the clamping jaw 14 moves relative to the threaded disk 13 in the radial direction. The two clamps 14 are close to each other to achieve the clamping of photographic accessories such as quick-release plates of different sizes. After clamping, there is no need to further lock with the help of locking structures such as the locking assembly 20. The structure is compact and simple, and the operation is convenient.
