Description

Technical Field

[0001] The utility model relates to the technical field of supporting frames, and more specifically, to a supporting frame for camera shooting. Background Art

[0002] When taking long-term photos with a camera, in order to improve shooting stability, the camera is generally mounted on a support frame, and then the camera is used to take photos. Most of the current camera support frames are in the form of a tripod, with three support legs folded together when not in use, and unfolded and supported on the ground when needed to improve support stability. The current support legs are generally fixed by tightening bolts after being unfolded. This method requires tightening three bolts, which is time-consuming and laborious. When one or more of the bolts are not fully tightened, the support leg is prone to rotation, causing the support frame to topple over, which in turn causes the camera to break, increasing costs. In addition, the length of many of the support legs in the current support frame can be adjusted according to usage requirements, but the adjustment method is generally by turning the screw to drive the support leg to retract. This method is difficult to achieve long-distance rapid adjustment and has a slow adjustment speed. Utility Model Content
