The quick connection assembly for photographic equipment includes a connecting sleeve having a first locking member and at least one second locking member; and a connecting head capable of being detachably connected with the connecting sleeve. The first locking member being configured to prevent an axial movement of the connecting head relative to the connecting sleeve, and the at least one second locking member being configured to prevent a rotation of the connecting head relative to the connecting sleeve. The first locking member can be rotated relative to the connecting sleeve to axially lock the connecting head in the connecting sleeve in an axial direction of the connecting sleeve, and release an axial locking of the connecting head in the connecting sleeve. ## Claims ### Claim 1 A quick connection assembly for photographic equipment, comprising: a connecting sleeve, comprising a first locking member and at least one second locking member; and a connecting head capable of being detachably connected with the connecting sleeve, wherein the first locking member is configured to prevent an axial movement of the connecting head relative to the connecting sleeve, and the at least one second locking member is configured to prevent a rotation of the connecting head relative to the connecting sleeve; and wherein the first locking member is rotatable relative to the connecting sleeve to axially lock the connecting head in the connecting sleeve in an axial direction of the connecting sleeve, and release an axial locking of the connecting head in the connecting sleeve, wherein when the connecting head is inserted into the connecting sleeve, the first locking member rotates relative to the connecting sleeve under an action of the connecting head, and then automatically engages with the connecting head, so that the connecting head is locked in the connecting sleeve in the axial direction of the connecting sleeve. ### Claim 2 (depends on 1) The quick connection assembly according to claim 1, wherein the connecting sleeve comprises a connecting section and a sleeve perpendicular to the connecting section, the connecting section at least partially covers an axial end of the sleeve, and the connecting head is receivable in the sleeve. ### Claim 3 (depends on 2) The quick connection assembly according to claim 2, wherein the first locking member is mounted in the sleeve and is able to partially enter into an inside of the sleeve to engage with the connecting head. ### Claim 4 (depends on 3) The quick connection assembly according to claim 3, wherein the connecting head comprises a main body having a substantially cylindrical shape with a annular groove arranged in a circumferential direction thereof, and a connecting plate arranged at an axial end of the main body; the first locking member partially enters into the annular groove in order to prevent the axial movement of the connecting head relative to the connecting sleeve, and the at least one second locking member cooperates with the connecting plate to prevent a rotation of the connecting head relative to the connecting sleeve. ### Claim 5 (depends on 4) The quick connection assembly according to claim 4, wherein the first locking member is rotatably mounted on the sleeve of the connecting sleeve through a first connecting member. ### Claim 6 (depends on 4) The quick connection assembly according to claim 4, wherein the first locking member comprises a tail that can be pressed by a user, a head that is pressed against the sleeve and is integrally formed with the tail, and a locking section extending from the head toward an inside of the sleeve, the locking section can enter the annular groove of the connecting head. ### Claim 7 (depends on 6) The quick connection assembly according to claim 6, wherein the tail is provided with a plurality of mounting sections extending toward the sleeve, a first elastic member is arranged between the plurality of mounting sections and presses the locking section into the sleeve. ### Claim 8 (depends on 6) The quick connection assembly according to claim 6, wherein the locking section has a first locking surface perpendicular to the head and a first slope extending from the head to the first locking surface, the first locking surface is arranged between the connecting section and the first slope. ### Claim 9 (depends on 8) The quick connection assembly according to claim 8, wherein the annular groove has a second locking surface capable of abutting against the first locking surface and a second slope capable of abutting against the first slope. ### Claim 10 (depends on 4) The quick connection assembly according to claim 4, wherein the at least one second locking member is fixed in the connecting portion and facing the sleeve, the connecting plate is provided with at least one location hole which is engagable with the at least one second locking member. ### Claim 11 (depends on 10) The quick connection assembly according to claim 10, wherein the at least one location hole comprises three location holes, and the at least one second locking member comprises three second locking members. ### Claim 12 (depends on 1) The quick connection assembly according to claim 1, wherein a buckle is provided on the connecting sleeve, a radial size of the connecting sleeve is variable by means of the buckle to clamp the connecting head in the connecting sleeve. ### Claim 13 (depends on 1) A photographic equipment assembly, comprising: a first photographic apparatus; and a second photographic apparatus; wherein the photographic equipment assembly further comprises the quick connection assembly according to claim 1, and the first photographic apparatus is connected to the second first photographic apparatus by the quick connection assembly.
