The main paddle rod (10) is connected to the detachable paddle rods (20, 30) by means of connecting portions (60, 70). The main paddle rod (10) is a hollow rod having a certain wall thickness and having a droplet-shaped cross-section. The detachable paddle rods (20, 30) having the same cross-sectional shape as the main paddle rod (10), and the detachable paddle rods (20, 30) can enter the main paddle rod (10), and fit with an inner wall of the main paddle rod (10) to move in an axial direction of the main paddle rod (10). The connecting portion (60) comprises a closed lantern ring (61) connected to the main paddle rod (10), a fastening device for fastening the detachable paddle rods, and a limiting device for limiting the detachable paddle rods.
