Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular relates to a hinged and detachable connection structure for a machine arm. Background Technology

[0002] The arms of multi-rotor drones account for a large portion of their volume. Therefore, in production and use, clips are installed at the connection between the arms and the fuselage to allow the arms to be folded or disassembled directly, achieving a result that minimizes the volume during transportation and storage. However, existing structures can only be folded or disassembled. While quick folding is the most convenient for transportation, such structures are often fixed. If disassembly is required due to arm damage, the operation is cumbersome and requires special tools. Although disassembly structures are easy to replace, removing all arms is time-consuming when the drone needs to be folded and moved during use. Therefore, developing a connection structure that can both hinge and fold quickly has been a problem that those skilled in the art have been pondering. Utility Model Content

[0003] The purpose of this utility model is to provide a hinged and detachable connection structure for the arm, which solves the technical problem in the prior art that the arm of a drone cannot simultaneously achieve folding and quick disassembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is:
