[0026] The present application provides a badminton racket for swing correction, which solves the problems in the prior art. In order to better understand the technical scheme of the present application, the above technical scheme will be described in detail below in conjunction with the drawings and specific embodiments.

[0027] The present application discloses a badminton racket for swing correction, referring to Figures 1-8 The device comprises a racket assembly 3, a back surface 2 movably mounted on the upper end of the racket assembly 3, and a front surface 1 rotatably mounted on the back surface 2. A symmetric reset spring 4 is connected between the back surface 2 and the front surface 1. The racket assembly 3 comprises a rod body 31, a handle 32 rotatably mounted on the lower end of the rod body 31, and a hand holding groove 33 opened on the handle 32. The back surface 2 is movably mounted on the upper end of the rod body 31. In the present technical scheme, the handle 32 and the rod body 31 are detachable. Athletes can replace the handle 32 with different directions of the hand holding groove 33 according to their habits. The materials of the back surface 2 and the front surface 1 are both light weight materials, which can be used for normal training of badminton.

[0028] The racket assembly 3 further comprises a limiting plate 35 fixed on the upper end of the rod body 31, a hexagonal convex block 34 fixed on the limiting plate 35, and a fastening cover 36 movably sleeved on the rod body 31 upward. An internal thread 361 is further opened on the inner side wall of the fastening cover 36.

[0029] The sub-surface 2 comprises a sound producing assembly 21 installed on the upper end of the back of the sub-surface 2, a limiting groove 22 fixed on the lower end of the sub-surface 2, and a connecting column 23 fixed on the bottom surface of the limiting groove 22, and an outer thread 231 is formed on the outer side wall of the connecting column 23. A six-rib groove 232 is formed on the bottom surface of the connecting column 23, and the six-rib groove 232 is movably clamped on the six-rib convex block 34, and the outer thread 231 is connected with the inner thread 361. The sound producing assembly 21 comprises a sounder 211 penetrating through the upper end of the sub-surface 2, a sound cell 212 installed on the back of the sub-surface 2, and a metal sheet 213 symmetrically installed between the sounder 211 and the sound cell 212, and the metal sheet 213 is electrically connected with the sounder 211 and the sound cell 212 respectively.

[0030] The front surface 1 comprises an on-off block 11 arranged on the back of the front surface 1, a connecting block 12 fixed on the lower end of the front surface 1, and a limiting shaft 13 symmetrically installed on both sides of the connecting block 12, the on-off block 11 corresponds to the position of the metal sheet 213, the connecting block 12 is located in the limiting groove 22, and the limiting shaft 13 is rotatably penetrated through the limiting groove 22.

[0031] In the implementation of the device, the racket is adjusted according to the hand habit when the player holds the racket, when the right hand holds the racket, the hand is held in the hand holding groove 33, and the face 1 is in the front; when the left hand holds the racket, the face and the handle 32 are adjusted; in the adjustment, the handle 32 is first rotated and disassembled, then the handle 32 with different direction hand holding grooves 33 is replaced and installed, so that the hand holding groove 33 is suitable for left hand holding; then the fastening cover 36 is loosened to cancel the limiting of the connecting column 23, then the six-rib convex block 34 is moved out of the six-rib groove 232, then the vice face 2 and the racket rod assembly 3 are rotated to flip, then the six-rib convex block 34 is moved into the six-rib groove 232, then the fastening cover 36 is screwed, and the internal thread 361 is connected with the external thread 231, because the lower part of the six-rib convex block 34 is provided with a limiting plate 35 for limiting the fastening cover 36, so when the fastening cover 36 is rotated to adhere to the limiting plate 35, the connecting column 23 is tightened and limited and fixed on the rod body 31. After adjustment, the hand is held in the hand holding groove 33 on the handle 32, and then the racket training is carried out; in the process of the forehand racket, when the racket action and the force are correct, the face 1 will rotate under the action of inertia, and will press the reset spring 4 and gradually approach the back of the vice face 2 when rotating, until the on-off block 11 adheres between the metal sheets 213, at this time, the sound generator 211 and the sound generating battery 212 are electrified, and the sound generator 211 emits a sound; when the force is not in place or the racket action is not correct, the face 1 cannot completely overcome the elastic force of the reset spring 4, and the on-off block 11 cannot adhere between the metal sheets 213, and the sound generator 211 will not emit a sound; therefore, the player can judge whether the racket action and the force are in place according to whether the sound occurs on the racket during the racket, and corresponding correction and training are carried out. When the racket is finished, the reset spring 4 pushes the face 1 to rotate and reset, and reaches a balanced fixed state under the limiting of the limiting groove 22, and at this time, the on-off block 11 is away from the sound generating assembly 21, the sound generator 211 and the sound generating battery 212 are disconnected, and the sound generator 211 stops emitting a sound. In the technical solution, the sound generator 211 and the sound generating battery 212 are prior art, the working principle of the electrical connection therebetween is prior art, the electrification working function is realized, and the specific working principle is not described in the technical solution.
