In this embodiment, the both ends of umbrella cloth can be dismantled with chuck 1 and many ribs respectively and be connected, can conveniently change. Specifically, the chuck 1 can be provided with a cloth pressing cover to be connected with the chuck 1 through the cloth pressing cover, so as to press and clamp one end of the umbrella cloth, and fix one end of the umbrella cloth on the chuck 1. And the other end of the umbrella cloth can be correspondingly provided with a plurality of plug connectors, and a plurality of umbrella ribs are correspondingly spliced and fastened on the plug connectors one to one so as to connect the umbrella cloth. Wherein, one end of the umbrella cloth is the central end thereof, and the other end is the peripheral end thereof. Optionally, a plurality of rod sleeve sets are arranged on the umbrella cloth corresponding to a plurality of umbrella ribs. A plurality of pole covers in the pole cover group are located on the rib along the length direction of rib in proper order to realize binding with the connection of rib. Wherein, the manufacturing material of the rod sleeve is selected according to the actual situation.

In summary, when the soft light box is in the open state, the limiting member abuts against one side of the first operating handle opposite to the first direction, each umbrella rib is in the open state, and the abutting member of each driving member is located at one end of the inclined groove close to the central axis of the chuck base; after the locating part is pressed manually, move first operating handle along with first direction antiport, hold the locating part and slide from its surface from pressing, the piece that supports of each driving piece slides along chute and injecing the groove, make the chute rotate to drive to support and slide in injecing the inslot, thereby driving piece drive umbrella bone seat extending direction changes, the articulated shaft slides in the spacing inslot, thereby realize that the umbrella bone pole draws close each other, later folding umbrella bone pole, further realize accomodating of soft case.

When the soft light box needs to be used, the umbrella rib rod in the folded state is opened, and then the first operating handle is moved to rotate along the first direction to slide on the surface of the limiting piece, so that the soft light box is opened.

What just go up be the utility model discloses a part or preferred embodiment, no matter be characters or the drawing can not consequently restrict the utility model discloses the scope of protection, all with the utility model discloses a holistic thought down, utilize the equivalent structure transform that the contents of the description and the drawing do, or direct/indirect application all includes in other relevant technical field the utility model discloses the within range of protection.
