The force is concentrated on the line connection part between the short shaft of the coupling frame and the outlet pipe seat, and the center of gravity is relatively high. Due to the excessive concentration of force, the automatic coupling device is easily damaged.

The coupling device includes an outlet pipe seat and a sewage pump, a sewage pump is arranged on one side of the outlet pipe seat, a guide rod is connected to the upper surface of the outlet pipe seat, a fixing mechanism is arranged on the top of the guide rod, and a coupling frame is sleeved on the top of the outlet pipe seat. In this coupling device, pulling the sewage pump can generate a pulling force on the coupling frame, and the coupling frame can drive the guide slide to slide on the surface of the guide rod under the pulling force, so that when the sewage pump moves upward to the water surface, the sewage pump can be removed and repaired at this time. Through this structure, the sewage pump is evenly stressed when pulled and is more stable.

[0004] Although the above patent improves stability, the flange of the sewage pump cannot be quickly positioned when connected to the screw hole of the outlet pipe, which affects the installation efficiency. In addition, the limiting mechanism of the coupling frame is provided, so that the stability of the operation of the device as a whole will be affected when it is impacted by the outside world.
