[0080] There will be a certain gear gap in the standard gear meshing, which will make it difficult to lock the gear shaft 2 when the pawl 3 is meshed with the gear shaft 2 to lock the gear shaft 2 due to the gear gap. Specifically, when the photographic equipment connection module is used, there will be a certain degree of shaking between the first photographic member 4 and the second photographic member 5. In order to solve this technical problem, the tooth portion of the gear shaft 3 in this embodiment has an abutting side surface, which is used to abut the pawl 3. The abutting side surface is a concave arc surface, and the curvature radius of the abutting side surface gradually decreases from the tooth top to the tooth root. The rotation radius of the pawl portion of the pawl 3 is smaller than the curvature radius of the abutting side surface at the tooth top, and larger than the curvature radius of the abutting side surface at the tooth root. When the pawl 3 is meshed with the gear shaft 2, the pawl portion of the pawl 3 is tightly abutted against the abutting side surface, eliminating the gap, thereby locking the gear shaft 2. In particular, when multiple pawls 3 are provided, the locking effect is better. Furthermore, the claw portion of the pawl 3 includes a metal layer and a hard rubber layer wrapping the metal layer. The abutment between the claw portion and the gear shaft 2 is safer, and there is a larger contact area between the claw portion and the tooth portion, which is beneficial to improving safety in use.
