The convex groove portion 510b may be provided on both sides with the concave groove portion 410b interposed therebetween. The outer surface of the convex groove portion 510b may be in contact with the first roller 521b of the bending member 220b for switch connection.

The protruding step 520b has a circular vertical cross-sectional shape, and a first roller 521b may be provided on an outer surface of the protruding step 520b. In addition, the first roller 521b may be in linear contact with the convex groove portion 510b and may be slidlessly sliding.

When the folding member 220b for connecting the switch is folded, the protruding step 520b may be partially line-contacted to the round bending surface 530b. Accordingly, the first roller 521b is rotated on the round bending surface 530b at a time when the pole-to-connection member 110b is folded approximately 50-60 degrees, so it can be rotated in a state in which the lifting and lifting force is reduced compared to the conventional one. .

Through the load reducing portion 500b, even when the one-touch switch portion 300b is pressed with less force than the conventional one when folding, the first roller 521b slides while being in contact with the cloud, so that the folding of the pole connecting member 110b can be easily performed. It can be easily and conveniently folded and unfolded to the user.

In addition, in the unfolding state, that is, in the state in which elasticity is applied to the pole, the curved surface portion 420b is inserted into the concave groove 410b of the locking portion 400b so that the elasticity applied to the pole is continuously connected to the speed ring. And can firmly support the softbox.

As described above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to specific embodiments, and should be interpreted by the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
