Description

Technical Field

[0001] This utility model relates to the field of photographic equipment, and in particular to a locking structure, cantilever and bracket. Background Technology

[0002] A support frame is a device used to support electrical components such as fan heads, lamps, shooting terminals, mobile phones, and tablets. The support frame typically includes at least two support rods connected by a rotating structure. Since users need to adjust the position of the electrical components, i.e., adjust the angle between the support rods, existing support frames generally use bolts and nuts to maintain the angle between the support rods while allowing relative rotation under external force. This locking structure relies entirely on the clamping force applied to the two support rods by the bolts and nuts, which is prone to loosening and inconvenient to use. Furthermore, the support rods are usually made of plastic, causing wear on the support rods after repeated friction between the bolt heads and the rods, further exacerbating the loosening of the support frame. Therefore, there is an urgent need for a locking structure, cantilever, and bracket to solve these problems. Utility Model Content
