The diameter of the outer cylinder of the air guiding device 9 and the piston column 905 is the same as that of the inner channel of the first connecting rod 2.

The working principle is as follows:

when the tennis racket is used, the hollow cavity support cavity 402 is formed in the three supports 401, when a tennis ball is impacted on the racket screen 503 of a player, vibration of the tennis ball on the ball surface frame 501 is firstly transmitted into the fixed frame 4 through the surface of the racket screen 503, at the moment, the three air bags 403 in the support cavity 402 are impacted and shaken in the support cavity 402, when the support cavity 402 shakes, water solution vibration in the support cavity 402 generates disordered rebound to drive the air bags 403 to impact the support cavity 402 and then reversely push the elastic T-shaped rod 504 to be extruded towards the direction of the racket screen 503, and the buffering force of the tennis ball impacting on the surface of the racket screen 503 on a holding part of the player at the racket handle 1 behind the fixed frame 4 is reduced.

Meanwhile, the support cavity 402 pushes the elastic T-shaped rod 504 to extrude the racket screen 503, at the moment, the tennis ball impact force on the net surface of the racket screen 503 restores the elastic deformation, the support cavity 402 pushes the elastic T-shaped rod 504 to extrude the side edge of the racket screen 503, the elastic T-shaped rod 504 accelerates the restoration time of the deformation of the net surface of the racket screen 503, the impact force on the surface of the racket screen 503 plays a role in protecting, and the service life of the racket screen 503 severely impacted by the net surface is shortened.

Meanwhile, the three fan-shaped cambered surfaces of the three supports 401 are welded and fixed with the outer surface of the spherical frame 501, the supporting effect between the fixing frame 4 and the racket surface 5 is enhanced, three triangular grooves are formed in the surfaces of the three supports 401, two bilaterally symmetrical triangular cavities are formed between the outer wall surfaces of the spherical frame 501, the triangular mechanism has stability, two triangular supporting points which correspond to each other are formed between the fixing frame 4 and the racket surface 5, and the stability of the fixed connection between the fixing frame 4 and the racket surface 5 is enhanced.

When a player swings the racket handle 1 back and forth, the racket handle 1 drives the supporting arc-shaped block 603 to swing back and forth, the supporting arc-shaped block 603 swings back and forth to drive the fan blade 605 to rotate back and forth on the supporting arc-shaped block 603, wind generated by the fan blade 605 rotating back and forth flows to the racket handle 1 in the inner part of the hemisphere of the supporting ball 601, the wind flowing to the outer wall surface of the racket handle 1 flows towards the movable groove 101 along the gap of the guide groove 102 on the racket handle 1, and the wind blown out from the guide groove 102 blows towards the palm center from the wrist of the player and blows towards the wrist of the player to perform the cooling effect.

When a player receives a long-time fatigue of a round-trip ball, when the player receives a violent impact ball, the wrist of the player falls off from the movable groove 101, the palm of the player slides downwards onto the guide groove 102, and a sliding friction is formed between the palm and the triangular groove of the guide groove 102, so that the holding force of the player on the racket handle 1 due to fatigue is avoided, when one side of the palm continues to slide backwards from the guide groove 102, the four semicircular support columns 602 are abutted against the joint of the downward sliding palm and the wrist, and the phenomenon that the racket falls off from the palm of the player is prevented for the second time.

By sleeving the protective sleeve 701 on the movable groove 101, when an athlete holds the air duct 702 from one side of any protective sleeve 701, the corresponding air injection holes 703 face the side of the palm of the athlete holding the palm of the athlete, meanwhile, the air duct 702 is wound in a staggered manner to be tightly attached to the contact surface of the palm and increase the friction force with the palm surface, so that the clamping degree of the athlete on the tennis racket is improved, when the athlete vigorously swings the tennis racket in a competitive game, the marbles 903 are collided in the second rod body 301 in a reciprocating manner, when the marbles 903 are collided towards the rear side, the marbles 903 are collided with the air guide slider 901 to squeeze the springs 904, the springs 904 squeeze the piston columns 905, the piston 905 compresses the air in the first connecting rods 2 from the abutting holes 802 to the corresponding air duct 702, then blows the air from the corresponding air injection holes 703 to the inner side of the palm on the sliding groove 302, and the palm blows air back to the place to lower the temperature of the athlete frequently, meanwhile, the phenomenon that sweat is easily caused by the sweating of the palm of the hand to reduce the frictional resistance between the palm of the hand and the air duct 702 and the protective groove 704 is avoided, and the phenomenon that the tennis racket falls off due to the fact that the racket is severely impacted by receiving a service ball is avoided.

When a player swings a tennis racket to discharge a ball, inertia generated when the player swings the racket handle 1 drives the three marbles 903 to roll towards the direction of the fixing frame 4 to strike the inner wall surface of the second rod body 301, at the moment, the impact force of the marbles 903 on the inner part of the second connecting rod 3 is transmitted to the spherical frame 501 and the racket filter screen 503 along with the three supports 401, the impact force of the marbles 903 accelerates to extrude the tennis outwards with the wall surface of the racket filter screen 503, the ball discharging speed is increased, meanwhile, the three marbles 903 pull the piston column 905 to pull towards the three supports 401 in the first connecting rod 2, at the moment, the air jet holes 703 on one side of the palm of the protecting sleeve 701 are tightly held, palm skin is sucked inwards, the holding force on the palm and the air guide tube 702 is enhanced, and the anti-slip effect is achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
