Mechanical arm quick release structure

The utility model discloses a mechanical arm quick release structure, which comprises a mechanical arm mounting part and a mechanical arm main frame, the mechanical arm mounting part and the mechanical arm main frame are respectively provided with a first mounting surface and a second mounting surface, and the second mounting surface is provided with a plurality of longitudinal mounting holes with narrow upper parts and wide lower parts. And the mechanical arm mounting piece and the mechanical arm main rack are assembled and connected through a fastener penetrating through the first mounting surface and the mounting hole. Through the structural design of the mounting hole in the main frame, the locking part of the fastener can directly pass through the lower half part of the mounting hole, so that the whole fastener can directly enter the narrow upper half part from the lower half part of the mounting hole along with the gravity trend of the main frame of the mechanical arm, and high-efficiency disassembly an
