Embodiment 1
[0040] In the handle of the racket according to the present invention, the surface of the handle is provided with a plurality of protruding structures for positioning the starting position and the ending position of the gripping finger and / or for guiding the gripping finger to slide from the starting position to the ending position boot surface. There are multiple raised structures, because it is necessary to provide support points for multiple fingers, that is, to provide support for the two main fingers of the thumb and index finger and the three auxiliary fingers of the middle finger, ring finger and little finger. point. In addition, the shape of the backhand and the forehand are different, and the positions where the fingers touch the handle are different, so corresponding support points need to be provided.

Embodiment 2
[0057] Such as Figure 10 As shown, the difference between Embodiment 2 and Embodiment 1 is that the second guide surface of the first protrusion 3 is stepped, that is, includes a first surface 3001 and a second surface 3002, wherein the second surface 3002 near the tail end It is concave relative to the first surface 3001 . In the starting position of the backhand grip, the stepped surface matches the length of the middle finger and ring finger, making it easier to hold.
[0058] In order to clearly show the distribution of the stress points of the handle or the handle of the second embodiment in the case of a forehand or a backhand, Figure 11 The settings of the force points in various situations are listed separately in , and these force points are the force points of the fingers. There are nine force points (force points) in total, and their specific distribution is also shown in Table 1. As shown above, the difference between the second embodiment and the first embodim...
