Abstract: A plugging rod connector includes a long plugging rod and a buckle device configured on the plugging rod. The buckle device has a positioning component on the top of the plugging rod. A crevice is formed between the positioning component and plugging rod. The two sides of the positioning component are respectively configured with a first locking component. An operation component having an operational portion is pivoted on the positioning component. The two sides of the operational portion are respectively configured with two parallel extension rods. A pivot shaft has its two ends being respectively perpendicular to the corresponding extension rods, making the operation component into a square-mouth shaped structure. The inner sides of the extension rods are respectively configured with a second locking component. The two second locking components are locked onto the corresponding first locking components, so that the operation component is temporarily unable to rotate or swing.
