Since the first telescopic taper head positioning pin and the second telescopic taper head positioning pin are both taper designed, the first telescopic taper head positioning pin and the second telescopic taper head positioning pin can be inserted into the positioning holes on the kayak paddle casting 24, so as to initially fix the position of the kayak paddle casting 24, and then the left end and the right end of the kayak paddle casting 24 are clamped by the first clamp and the second clamp respectively, so as to achieve the purpose of completely fixing the kayak paddle casting 24. Since the lower end of the top rod 17 is provided with the elastic member 19, after the kayak paddle casting 24 is placed, the top end of the top rod 17 can be abutted against the two ends of the kayak paddle casting 24, and then the two ends of the top rod 17 are fixed by the lock, so that the top rod 17 cannot move longitudinally. Since the elastic member 19 is arranged at the lower end of the top rod 17, after the lock locks the two ends of the top rod 17, the elastic member 19 loses the effect on the top rod 17, so that the top rod 17 cannot move.
