The control method for the distribution cabinet detection device as described in claims 1-9, characterized in that, Includes automatic wiring and manual wiring: The automatic wiring includes the following process: A00: Transmit control commands to the controller (62) via a remote control terminal; A01: The controller (62) controls the servo motor (4) to start according to the control command; A02: The servo motor (4) drives the vertical screw (31) to rotate, and the vertical screw (31) drives the horizontal connecting rod (33) and several insulating blocks (32) to move upward; the insulating blocks (32) drive the corresponding lower electrical post (22) to move upward and make contact with the energized plate (23); The manual wiring includes the following process: When the connecting assembly includes a sliding lock head (51) and a spring (52), the rotating column (5) is lifted upwards, and the sliding lock head (51) compresses the spring (52) into the annular groove (314). The tooth A (511) meshes with the tooth grooves between two adjacent teeth B (313). Then, the rotating wheel (54) is rotated to drive the rotating column (5) and the vertical screw (31) to rotate. The vertical screw (31) drives the horizontal connecting rod (33) and several insulating blocks (32) to move upwards. The insulating blocks (32) drive the corresponding lower electrical terminal (22) to move upwards and make contact with the energized piece (23). When the connecting assembly includes the limiting prism (53), the rotating wheel (54) is directly rotated to drive the rotating column (5) and the vertical screw (31) to rotate. The vertical screw (31) drives the horizontal connecting rod (33) and several insulating blocks (32) to move upward. The insulating block (32) drives the corresponding lower electrical post (22) to move upward and make contact with the energized piece (23).
