[0042] Furthermore, the first quick-release part 1 may also include a cover plate 205, which covers the wire harness groove 204. The cover plate 205 can protect the wire harness groove 204 and the wire harness.

[0043] The process of using the quick-release structure of this robotic arm is as follows: First, the first quick-release part 1 is connected to the arm body 501 via a connector such as a fastening bolt. Since the first connection position 104 is a round hole, the first quick-release part 1 can cooperate with the arm body 501 and can move around the joint of the arm body 501. Then, the rotation limit block 302 is sleeved on the rod portion 305 of the rotating screw 303, and the rotating screw 303 is set on the connecting block 301. In the embodiment, the connecting block 301 may include upper and lower parts for easy assembly, and these two parts can be connected to each other via a connector such as a fastening bolt.

[0044] This robotic arm utilizes a quick-release structure, with the cooperation of a first quick-release section, a second quick-release section, and a locking section, enabling rapid assembly and disassembly. Due to its simple overall structure and few parts, the assembly and disassembly process is simple, convenient, efficient, and cost-effective. Furthermore, because the first and second quick-release sections are mechanically connected, disassembly can be performed at any time during production without damaging the existing production line or electrical system. The locking section requires the user to use an identification device to lock or unlock the locking assembly, thereby enabling the connection and separation of the first and second quick-release sections. This ensures that only authorized users can perform the disassembly, guaranteeing production safety.
