The standard gear engagement has a certain gear clearance, which causes the pawl 3 to be difficult to lock due to the gear clearance when engaging with the gear rotating shaft 2 to lock the gear rotating shaft 2, and particularly causes a certain shaking between the first photographing part 4 and the second photographing part 5 when the camera equipment connecting module is applied. In order to solve the technical problem, in the present embodiment, the tooth portion of the gear shaft 3 has an abutment side surface for abutting the pawl 3, the abutment side surface is a concave arc surface, a curvature radius of the abutment side surface is gradually reduced from the tooth crest to the tooth root, and a claw portion rotation radius of the pawl 3 is smaller than a curvature radius of the abutment side surface at the tooth crest and larger than a curvature radius of the abutment side surface at the tooth root. When pawl 3 and gear shaft 2 meshing, the claw of pawl 3 closely supports with the butt side, eliminates the clearance to lock gear shaft 2, especially when setting up a plurality of pawls 3, locking effect is better. Furthermore, the claw part of the pawl 3 comprises a metal layer and a hard rubber layer wrapping the metal layer, the claw part is more safely abutted against the gear rotating shaft 2, and the claw part and the tooth part have larger contact area, so that the use safety is improved.
The invention further provides a photographic assembly, which refers to fig. 1, and comprises a photographic equipment connecting module, a first photographic element 4 and a second photographic element 5, wherein one end of a gear rotating shaft 2 is used for connecting the first photographic element 4, a shell 1 is used for connecting the second photographic element 5, when a pawl 3 and the gear rotating shaft 2 are in a disengaged state, the first photographic element 4 and the second photographic element 5 can rotate relatively, and when the pawl 3 and the gear rotating shaft 2 are in an engaged state, the first photographic element 4 and the second photographic element 5 are in a locked state.
Further, the first photographing part 4 is any one of a threaded interface, a slide bar interface, an alai interface and a cold boot interface for externally connecting other photographing parts, the second photographing part 5 is any one of a handle, a protective frame and a support, and the camera equipment connecting module is positioned inside or outside the second photographing part 5.
