The present invention disclosed a paddle, which includes a blade and a hollow lower shaft that connects to the blade. The hollow lower shaft is capable of receiving a rod and an upper shaft capable of entering and moving within said lower shaft; with one end of the upper shaft connected to the rod and able to move simultaneously with the upper shaft within the lower shaft. Wherein, the material of the rod within the hollow lower shaft is different from that of the hollow lower shaft, and the paddle is less likely to break instantaneously.
