[0003] The currently used wire harness terminal crimping detection device still has the following problems: 1. The electric telescopic rod can only detect one wire harness each time it is extended and retracted, and cannot detect two wire harnesses, which reduces the efficiency of the crimping detection of the wire harness terminals; 2.

Generally, the crimping effect of the wiring harness terminal is judged by observing whether the wire and the terminal are separated. When the terminal is crimped on the insulation layer of the wire, the wire and the terminal may not be separated, resulting in low detection efficiency. Summary of the Invention
