The retractable guide pipe tandem propeller comprises a tandem propeller body and an external guide pipe, the tandem propeller body comprises a tandem propeller body and a propeller shaft body connected with the tandem propeller body, the external guide pipe comprises a guide pipe body and a retractable mechanism connected with the guide pipe body, and the retractable mechanism comprises a guide pipe connecting rod piece and a transmission rotating mechanism. The end of the catheter body is connected with a catheter connecting rod piece through a transmission rotating mechanism, the input end of the catheter connecting rod piece is connected with a driving device, and the driving device can drive the catheter connecting rod piece to move horizontally. Through the guide pipe retracting and releasing system, the propelling efficiency of the propeller is improved under the condition that the diameter of the propeller is limited. Through horizontal movement and retraction cooperation of the tandem propellers and the guide pipe, the propelling efficiency of the propeller is improved, and different modes are adopted in different scenes, so that related requirements can be better met.
