5 . The quick-release assembly according to claim 4 , wherein,

the at least one slant groove is defined in the driving member; and

the at least one driving part is provided on a side surface of the sliding member away from the avoidance groove;

wherein when the driving member slides, the at least one driving part slides along an inner wall of the at least one slant groove to push the sliding member to slide.

6 . The quick-release assembly according to claim 5 , wherein the driving member extends along a front-rear direction of the mounting base, a sliding direction of the sliding member is substantially perpendicular to a sliding direction of the driving member, an extending direction of the at least one slant groove is at an included angle with the sliding direction of the sliding member, and the extending direction of the at least one slant groove is also at an included angle with the sliding direction of the driving member.

7 . The quick-release assembly according to claim 5 , wherein the sliding member is one of two sliding members, the two sliding members are arranged in parallel and spaced apart, each sliding member is elongated, and the driving member simultaneously drive the two sliding members to slide.

8 . The quick-release assembly according to claim 7 , wherein each sliding member is provided with two driving parts spaced apart, the driving member is defined with four slant grooves arranged at intervals, and the four slant grooves extend in a same direction.

9 . The quick-release assembly according to claim 7 , wherein,

the avoidance groove is transversely formed in the sliding member, and two ends of the avoidance groove define openings; and

the sliding member is provided with at least two avoidance grooves, one of the at least two avoidance grooves is formed at an end of the sliding member; the avoidance groove at the end of the sliding member is defined by an arc side wall and a bottom wall, and the bottom wall extends out of the end of the sliding member.

10 . The quick-release assembly according to claim 1 , wherein the fixing slot is defined by a first side plate and a second side plate facing each other;

wherein one of the first side plate and the second side plate is movable, or both the first side plate and the second side plate are movable.

11 . The quick-release assembly according to claim 10 , wherein the first side plate is movable relative to the second side plate, a side wall of the first side plate is mounted with an adjustment screw rod, the adjustment screw rod passes through the first side plate and is threadedly connected with the mounting base, and a head portion of the adjustment screw rod is exposed on an outer surface of the first side plate.

12 . A photography accessory, comprising:

an accessory body; and

the quick-release assembly of claim 1 ; wherein,

the mounting base of the photography accessory is connected with the accessory body.

13 . A quick-release kit, comprising:

a structural member; and

the photography accessory of claim 12 , the quick-release assembly of the photography accessory being detachably connected with the structural member;

wherein the structural member comprises a first frame, the first frame is defined with a plurality of engaging grooves arranged in parallel and at intervals; and

after assembly, one end of the resisting member extends out of the bottom wall surface of the fixing slot, to abut against an inner surface of one of the plurality of engaging grooves.
