The hanging arm has main mechanical connectors that demarcate main slide to transverse direction. The main electricity plug is reversed in main housing to engage main housing and sub-mechanical connector at backward position and is protruded to main front opening at advance position. A plug is extended by guidance finger extending in right angle direction with respect to longitudinal direction shaft. The main electricity plug is moved between backward position and advance position by moving inside of groove in cam that is turned with respect to main case. |
