Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

The utility model relates to an improved generation antitorque racket, as shown in fig. 1-3, including frame 01, triangle position, racket shaft 02, net twine and handle section 03, the net twine is woven in frame 01 inside formation batting face, triangle position is connected between frame 01 and racket shaft 02, and handle section 03 is connected in the one end that frame 01 was kept away from to racket shaft 02. The triangular portion is substantially an inverted triangle, and includes a header 04 at the bottom and a yoke 05 at two oblique sides, the opposite sides of which are the inner sides.

The inner side surface of the yoke 05 is a plane 06 which is convenient for air to penetrate through so as to reduce wind resistance, the outer side surface of the yoke 05 is an outward convex arc surface 12, the plane 06 and the convex arc surface 12 are connected together smoothly, the circumferential section of the yoke 05 is of an axisymmetric structure, the symmetry axis of the axisymmetric structure is parallel to the striking face, and preferably, the symmetry axis is located in the plane where the striking face is located. The design that yoke portion 05 adopted "interior flat outer arc" is convenient for increase the frequency that the user rotated the racket before the batting at will, and then reduces muscle fatigue degree.

The circumferential cross-section of the racket shaft 02 is H-shaped. Which is helpful for improving the torsion resistance of the racket frame 01 when hitting the ball. Meanwhile, the stability of hitting the racket frame 01 can be enhanced, the handfeel of holding the racket by hands can be enhanced, the holding manner can be changed rapidly, and the muscle fatigue of a user can be reduced.

The frame 01 is substantially elliptical, and the extreme end position of the frame 01 away from the shaft 02 is twelve o 'clock, and the determination of the o' clock direction is a position determination method commonly used in the art and will not be described in detail herein. The racket frame 01 is provided with a threading hole for weaving a net thread, and the axis of the threading hole and the hitting surface are positioned in the same plane. The through wires hole includes conventional hole 07 and hole enlargement 08, and hole enlargement 08 is located racket frame three point and nine point positions, the utility model discloses in, the position of seting up of through wires hole with lay density etc to and the weaving mode of net twine is the known technique in the trade, do not give detailed description here. Preferably, the diameter-expanding hole 08 is an inner diameter-expanding hole, and the threading hole on the inner side wall of the racket frame 01 is designed to be expanded. The racket frame is provided with 6 inner diameter expanding holes which are uniformly distributed at three points and nine points respectively, and the aperture of the diameter expanding hole 08 is larger than 4.5 mm. The threading holes at three points and nine points of the racket frame 01 are designed in an inner expanding mode, so that the fault tolerance of the string bed is higher, a sweet area (namely an optimal hitting area) is enlarged, the threading mode can be contracted more freely by increasing the diameter of the string hole, the hitting is smoother, and clear hitting feeling can be transmitted.

The racket frame 01 adopts an inward convex thickening design at two points and ten points to form a reinforcing part 09. The reinforcing portion 09 increases the impact strength of the racket, thereby increasing the lifespan of the racket, since the racket is likely to hit the ground, etc. when in use.
