Further, the middle rod is of a circular structure; the round edge is safer and smoother, protects, and increases safe usability.
Further, the middle rod is made of aluminum; low cost and good torsion resistance.
Further, the unidirectional composite material adopts a carbon fiber composite material; the carbon fiber has light weight and high strength, and the strength is increased under the condition of ensuring the light weight.
Further, the anti-torsion structure is an inward convex arc-shaped boss or square structural rib; the boss is arranged on the inner side of the rod wall to increase the torsional strength of the middle rod and prevent breakage.
Compared with the prior art, the utility model has the following advantages and effects: the internal structural ribs are arranged in the middle rod, so that the strength of the middle rod is enhanced, the batting force is transmitted more efficiently during batting, the batting hand feeling of the badminton racket is improved, the torsion resistance strength of the racket is enhanced, the weight reduction is ensured, the racket is effectively prevented from being broken, and the service life is prolonged.
