This design has the disadvantages of: the spin ball cannot be generated, the actual training is that the spin ball is very necessary, the timely coping strategy and action of the training players on the spin ball are one of the basic purposes of the training, and different spin can bring different track effects of the ball. When the ball flies forward without rotating, the air on the upper, lower, left and left surfaces of the ball flows backward at the same speed. If the ball body rotates upwards, air on the upper part of the ball is driven to flow forwards and is abutted against the air flowing backwards, so that the air flow rate on the upper part of the ball is reduced, and the pressure is increased; the upward rotation of the ball drives the air at the lower part of the ball to flow backwards, and the air flow velocity at the lower part of the ball is increased and the pressure is reduced. Thus, the ball is pressed down quickly in flight due to the large upper pressure and the small lower pressure of the ball, and a falling parabola track is formed. The faster the rotation, the faster the descent speed. Similarly, the downward rotating ball flies upward and the side rotating ball inclines. The hit ball cannot rotate, which is very different from the actual serving effect, and thus cannot adapt to the high-quality training effect.

(3) step S3, the blocking of the ball hitting rod is released, the ball hitting rod moves forward rapidly under the action of the power storage spring, the rotating pressure rod moves outwards relative to the radial direction of the ball at the same time, the lower end of the rotating pressure rod is separated from the surface of the ball, then the ball with spin is impacted by the ball hitting rod rapidly,
in step S2, the direction of spin is adjusted by adjusting the rotation of the rotary pressure lever with respect to the axis of the pusher cylinder.
2. The multi-angle adjustable serve method of sports apparatus of claim 1, wherein: in the step S3, after the lower end of the rotating compression bar is separated from the surface of the ball, at least two inner core rods are pushed on the surface of the ball, and the end faces of the inner core rods are hemispherical surfaces, so that the contact surface between the inner core rods and the ball is reduced, and therefore, the position deviation of the ball is not too large at the moment of separation of the rotating compression bar.
3. The multi-angle adjustable serve method of sports apparatus of claim 1, wherein: in the above step S3, the ball striking shaft passes through the middle of the feed cylinder. Therefore, the propelling uniformity is ensured in the process of propelling the ball by the propelling cylinder, the ball striking rod impacts from the middle, the contact surface is less, and the self-spinning influence on the ball is smaller.
