Abstract: A soft box includes a housing and a main body detachably connected to the housing by a connecting device. The connecting device includes a first locking portion and a second locking portion. An installing base is connected to the bottom of the housing and the main body is embedded in the installing base, thereby the housing can rotate around the main body. The first locking portion passes through the installing base and the main body to tightly fix with the second locking portion. The housing includes a snap-fitting member and a light passageway which is a cylindrical hole and a flash lamp cap fixing device formed therein. The flash lamp cap fixing device includes a supporting platform and a pressing plate opposite to the supporting platform and having an adjustable position relative to the supporting platform. The present disclosure can quickly disassembly and be easy to carry.

Abstract: An occlusion device comprises a distal end, a proximal end and an elastic braided body which is provided between the proximal end and the distal end and made of wires. The elastic braided body is composed of a multi-stage braided net, which comprises at least a first-stage braided net that is closest to the distal end and made of a plurality of first-stage wires, and a second-stage braided net which is braided by a plurality of first-stage wires and second-stage wires all together. The minimum cross-section area of the first-stage braided net after being compressed toward the direction perpendicular to an axis of the elastic braided body is less than the minimum cross-section area of any other-stage braided net after being compressed toward the axis. A method for manufacturing the occlusion device is also provided.

Abstract: Provided is a snap-fitting device for a softbox, comprising: a casing, on which a supporting member (6), a snap-fitting member and a light passage hole (4) are formed.
