Description of the invention: [Technical field to which the invention pertains] The present invention relates to a type of racquet, and more particularly to a racquet which can be combined with different softness and hardness to make a multi-stroke effect, and is suitable for different strengths. User's racket. [Prior Art] See the picture-like racket! The invention comprises: a ring frame 2, a grip 3 connected to the ring frame 2, and a _4 disposed on the ring frame 2. In the prior art, the badminton racket is taken as an example. The ring frame 2 has an arc-shaped bottom portion 21 and an arcuate top portion 22 with respect to the bottom portion η. The grip 3 is disposed at the bottom 21 of the ring frame 2, and has a grip, and a rod U disposed on the bottom 31 of the grip 31. The rod 32 is typically made of an alloy (e.g., titanium alloy, alloy) or a composite material (e.g., carbon fiber). The racquet net 4 includes a plurality of warp threads 41 extending from the bottom 21 of the ring frame 2 toward the top portion 22, and a plurality of weft threads 42 interlaced with each of the warp threads 41. The aforementioned warp and weft threads 41, 42 can jointly define a main ball striking portion c, and a second hitting portion Φ and a bit hitting ball portion located at the periphery of the main ball striking portion c and connected to the ring frame 2 C* is surrounded by two adjacent warp and weft lines 41, 42 == mother-mesh 40 is nearly equal in size, and the distance between the main hitting ball == neighboring weft line 42 is toward the bottom of the ring frame 2 21 Box 2: Guangqi gradually grows big, that is, each mesh 40 is directed toward the bottom of the ring. The direction of the 卩21 and the top 22 gradually increases. 200819169 The racquet 1 has the above-mentioned design, so that the surface tension and the elastic force of the central portion of the main ball striking portion c are larger, and the ball has a greater force at the moment of swinging the badminton ball. The sweet spot of the ball mainly falls in the central area of the main hitting portion C. When the hitter grasps the center of the ball on the main hitting ball C at the moment of hitting the ball, it can produce a good swinging force and achieve a strong hitting effect. In addition, under the same force, the larger the force arm is, the greater the torque is generated. When the badminton ball is hit by the upper portion of the main ball striking portion C, the force arm of the swipe is larger than the towel area. The hitting force of the created ^ will be larger, and the speed of the badminton flying will be faster; on the contrary, when the badminton is hit by the lower part of the main hitting portion C, the swiping force arm: short to the central area The resulting impact is less and the badminton is slower. However, with the design of the racket 1, if the hitter of the general strength fails to actually place the buff on the central area of the main hitting portion c, it will not produce a good swing force, and it is difficult to achieve Strong hitting effect. Furthermore, 'because the surface tension and elastic force of the upper part of the main hitting part c have gradually become less, the force exerted on the badminton during the swing will also shrink. The arm of the upper badminton ball in the upper portion of the main hitting portion C is used to extend the arm to achieve a strong hitting effect, which is also limited. For the general strength, for the general strength, if the ball is made with the lower hardness and the elasticity of the same body 32, although it can provide a more relaxed and comfortable swing, but Failure to grasp that the badminton ball is placed in the main hitting ball 40, and the product range day $ can not achieve a good hitting effect; in addition, for the strength of 200819169, if the hardness is higher, the elasticity is lower. Although the racket 1' made by the rod 32 can increase the speed of the swinging racket i, the speed and explosive force of the badminton flying are also limited. Therefore, the design of the racquet 1 is difficult to meet the needs of different strengths, whether it is made of a rod 32 having a lower hardness or a higher hardness. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a racquet which can be combined with different softness and hardness to make a multi-stroke effect, and is suitable for different strengths. The shot is a frame comprising a ring, a grip, and a net set on the ring frame. Each of the laps and the latitude lines jointly define a main ball striking portion, and a sub-ball striking portion located at the periphery of the main ball striking portion and connected to the ring frame, and located at the 5th main hitting portion and two The size of each mesh surrounded by adjacent warp and weft lines is gradually changed from the bottom of the ring frame toward the top. The invention is designed by the following, for example, when the mesh is gradually increased by the ring frame, the sweet spot of the hitting ball can be spread over the whole ball on average. "When the ball of the general strength is not at the moment of hitting the ball, It can also grasp the effect of brandanuo when it is placed on the main hitting point of the main ball striking part. At the same time, it can be matched with the rod with softer hardness and higher elasticity: white can provide A more relaxed and comfortable swing experience, in order to increase the direction of sports music gradually shrinking, such as each mesh is from the bottom of the ring frame toward the top 200819169 P Φ ξ: liter 4 surface tension and elasticity of the upper part of the main hitting ball, and It has a large impact force on the sphere. Therefore, when the better-performing player hits the brute force attack, he can choose to use the upper sphere of the main hitting ball to swipe the ball to extend the arm. Strong hitting force; at the same time, the racquet made by the harder and less elastic rod can increase the impact force generated by the badminton ball to greatly increase the swing racquet and the ball flight. The speed of the present invention The design can be combined with different softness rods to make a multi-stroke racquet for different strength users. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are combined in the following The detailed description of the two preferred embodiments of the drawings will be clearly described. Before the present invention is described in detail, it is noted that in the following description, like elements are Referring to FIG. 2 and FIG. 3, the racket 5 of the present invention comprises: a ring frame 6, a grip 7 connected to the ring frame 6, and a net 8 disposed on the ring frame 6. In this embodiment In the example, the badminton racket is taken as an example. Of course, the present invention can also be designed to make a tennis racket, or a racquet, which is not limited to the badminton racket of the embodiment. 6 has an arc-shaped bottom portion 61, and an arcuate top portion 62 opposite to the bottom portion 61. The grip rod 7 is provided at the bottom portion 61 of the ring frame 6. The grip rod 7 has a grip 71 And a rod disposed at the end of the grip 71 and connected to the bottom 61 200819169 Body 72. The web 8 includes a plurality of warp threads 81 extending from the bottom 61 of the ring frame 6 toward the top q, and a plurality of weft lines interlaced with each warp line 81. The aforementioned warp and weft lines 81 and 82 are defined together. a main hitting portion A (the range surrounded by the imaginary line of 82 3), and a hitting portion B connected to the ring frame 6 at the main hitting portion a ° and located at the main hitting ball The portion a and the two adjacent warp and weft lines 81, 82 are surrounded by each of the meshes 8 is gradually increased from the bottom 61 of the two frames toward the top 62. In this embodiment, the net 8 is located The interval 15 between the two weft lines 82 of the main ball striking portion is gradually increased from the bottom 61 of the ring frame 6 toward the top 62; further, the net 8 is located adjacent to the main ball portion The spacing of the holes 81 is also from the bottom 62 of the ring frame 6 toward the top 61. The racket 5 of the present embodiment is designed such that the sweet spot of the hitting ball is spread over the entire main ball striking portion A. The reason is that each mesh (10) is gradually increased from the bottom 61 of the ring frame 6 toward the top 62, and the surface tension and the elastic force are gradually reduced relative to each other; Under the force of force, the greater the force of the arm, the greater the moment, so the moment generated by the ball will gradually increase from the bottom 61 of the ring frame 6 toward the top 62, thus reducing the surface tension and the elastic force. The effect of the increase in torque is 17 so that the force exerted by the main ball hitting portion A on the badminton ball tends to be averaged, so that the sweet spot of the hitting ball is spread over the entire main hitting portion A. When the player of the general strength fails to grasp the ball at the moment of hitting the ball; when hitting the preset hitting point on the East A, the force generated by the entire main hitting part a 200819169 tends to average, Therefore, it is possible to achieve a solid and ideal #球放果. In addition, the racquet 5 made of the rod body μ with softer hardness and higher elasticity can provide a more relaxed and comfortable swinging feeling. Therefore, the racket 5 of the present embodiment is more suitable for the general hitter. = Fig. 4 and in conjunction with Fig. 5, the second preferred embodiment of the racket 5 of the present invention also includes: a ring frame 6, a grip 7 connected to the ring frame 6, and a tennis racket or a squash racket The badminton racket that is not used in the embodiment is: the net 8 provided on the ring frame 6. In the present embodiment, the badminton racket is still taken as an example. #然,本发(四) may be one of the above-mentioned beats, A - hour 1 ^ ^ is different from the foregoing first preferred embodiment in that it is located in the main hitting portion and is adjacent to the two The mesh 8 around each of the wefts 81, 82 is gradually reduced from the bottom 61 of the ring frame 6 toward the top 62. In this embodiment, the spacing of the web 8 at the adjacent wefts 82 of the main ball striking portion A is gradually reduced from the bottom 61 of the ring frame 6 toward the top μ direction; The pitch of the two adjacent warp threads 81 of the main ball striking portion A is also gradually reduced from the bottom 61 of the ring frame 6 toward the top portion. The racket 5 of the embodiment can be designed such that the surface tension, the elastic force and the maximum torque generated are concentrated on the upper portion of the main ball striking portion A. The mouthpiece 80 is the ring frame 6 The bottom Μ gradually shrinks toward the top , direction, and its surface tension and elastic force will gradually increase. And under the same force of swinging the racquet 5, the greater the force of the arm, the greater the moment, so the hitting place The generated torque will gradually increase from the bottom Η 10 200819169 of the ring frame 6 toward the top 62; thus, in the case where the surface tension, the elastic force and the torque are increased, the upper portion of the main ball striking portion A can be made. Great impact on the badminton. Although the better-performing hitter is in the moment of hitting the ball, if you want to carry out a strong smash attack, you can choose to use the badminton ball in the upper part of the main hitting ball A to extend the arm, which can produce a larger hitting effect. force. In addition, the hardness is harder? The racquet 5 made of the lower-lower pole 72 can increase the impact force generated by the badminton ball to greatly increase the speed of the racquet 5 and the badminton, and achieve a strong attack. effect. Therefore, the racket 5 of the present embodiment is more suitable for the player who is better in strength. In summary, the present invention can be designed to match the rod body 72 of the ball 7 of different hardnesses to form a multi-bar shot racquet 5, which is suitable for users of different strengths. The purpose of the present invention is achieved by selecting the appropriate hitting point for the buff to fall on the main hitting ball A to produce a different hitting force on the badminton. However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the practice of the invention, that is, the simple variations and modifications made by the invention according to the invention and the scope of the invention. All remain within the scope of the invention patent.
