Two threading holes are symmetrically arranged at the 12 o ' clock position of the racket frame, the threading hole positioned at the left half part of the racket frame is defined as a left first hole at the 12 o ' clock position, other threading holes positioned at the left side of the left first hole are sequentially defined as a left second hole, a left third hole and a left fourth hole … …, the threading hole positioned at the right half part of the racket frame is defined as a right first hole at the 12 o ' clock position, and other threading holes positioned at the right side of the right first hole are sequentially defined as a right second hole, a right third hole and a right fourth hole … …

2. The threading pound number of the racket is set according to the requirements of a user or the application scene of the racket, wherein the pound numbers of the transverse lines and the vertical lines are set to be the same value.

3. The badminton line is not cut off, the badminton line is divided into two sections only by measuring the length, so that the first section of the badminton line is shorter than the second section, and preferably, the first section is shorter than the second section by 2.5M-3M; wherein, the first section is used for wearing the vertical line of the left half of the racket frame, and the second section is used for wearing the vertical line of the right half of the racket frame and all the transverse lines of the racket frame.

4. The vertical lines of the badminton racket penetrate through the racket frame. During threading, starting threading by taking the 12 o ' clock position of the racket frame as a thread starting point, enabling a first section of a badminton thread to penetrate through a first left hole 41 at the 12 o ' clock position, penetrate out of a first left hole at the 6 o ' clock position, penetrate through a second left hole at the 6 o ' clock position, penetrate out of a second left hole at the 12 o ' clock position, and repeatedly penetrate through a vertical line on the left half part of the racket frame; after the first section of the badminton line passes through the ninth hole 61 at the left side at the 6 o 'clock position, the tenth hole and the eleventh hole at the left side at the 6 o' clock position are skipped, and the first section of the badminton line passes through the twelfth hole 62 at the left side at the 6 o 'clock position and passes through the eleventh hole 42 at the left side at the 12 o' clock position; then the thread is penetrated through the tenth hole on the left side at the 12 o ' clock position and is penetrated out through the tenth hole on the left side at the 6 o ' clock position, and the knotting treatment is carried out at the eighth hole 63 on the left side at the 6 o ' clock position.

Referring to the method for threading the vertical line on the left half of the racket frame, threading is started by taking the 12 o ' clock position of the racket frame as the starting point, the second section of the badminton line penetrates through the first hole 51 on the right side of the 12 o ' clock position, penetrates out from the first hole on the right side of the 6 o ' clock position, penetrates through the second hole on the right side of the 6 o ' clock position and penetrates out from the second hole on the right side of the 12 o ' clock position, and the vertical line on the right half of the racket frame is threaded in a reciprocating manner; after the second section of the badminton line passes through the ninth hole 71 at the right side at the 6 o 'clock position, the tenth hole 72 and the eleventh hole 73 at the right side at the 6 o' clock position are skipped over, and the twelfth hole 74 at the right side at the 6 o 'clock position penetrates through the eleventh hole at the right side at the 12 o' clock position and passes through; and then through the tenth hole on the right at 12 o 'clock and out through the tenth hole 72 on the right at 6 o' clock.

5. The racket frame is provided with a horizontal line of the badminton racket in a penetrating way. After the vertical line on the right half part of the racket frame is arranged in the second section of the badminton line in a penetrating manner, the second section of the badminton line penetrates out of the tenth hole 72 on the right side at the 6 o ' clock position, and then the second section of the badminton line penetrates in from the ninth hole 71 on the right side at the 6 o ' clock position and penetrates out of the ninth hole 61 on the left side at the 6 o ' clock position; then the badminton thread penetrates through the tenth hole on the left side at the 6 o 'clock position and penetrates through the tenth hole on the right side 72 at the 6 o' clock position, so that the badminton thread is penetrated through the threading holes on the left half part and the right half part of the racket frame in sequence along the direction from the 6 o 'clock position of the racket frame to the 12 o' clock position of the racket frame in a reciprocating manner to form a transverse line on the racket frame until the second section of the badminton thread penetrates through the seventh hole 52 on the right side at the 12 o 'clock position, and the knotting treatment is carried out at the sixth hole 53 on the right side at the 12 o' clock position.

Preferably, in the process of passing through the vertical lines, the vertical lines of the left half and the right half of the racket frame are alternately passed through. For example, first, a first section of the badminton line is used for penetrating a first vertical line on the left half part of the racket frame, then a second section of the badminton line is used for penetrating the first vertical line on the right half part of the racket frame, then a second section of the badminton line is used for penetrating a second vertical line on the left half part of the racket frame, and a second section of the badminton line is used for penetrating the second vertical line on the right half part of the racket frame in a reciprocating and alternating way; alternatively, the alternate threading may be performed in such a manner that two or three threads are alternately passed in a reciprocating manner. The alternate penetrating mode can enable the left half part and the right half part of the racket frame to be more balanced in tension from the ball line, so that the overall stress of the racket is more balanced, and the stability and the use experience of the sports performance of the racket are improved.

Preferably, in the process of threading the transverse line, the threading can be carried out in a mode of pulling the badminton line and simultaneously shifting the badminton line up and down. Because the badminton line is directly and quickly drawn, relatively violent friction is generated between the transverse line and the vertical line which is already drawn, and then a large amount of heat is generated, and the heat can cause the badminton line made of nylon or other heat-labile materials to generate dents, thereby influencing the motion performance of the badminton line. And the line-shifting mode can reduce or lighten the friction between the transverse lines and the vertical lines, thereby prolonging the service life of the wire rods and ensuring the sports performance and the use experience of the badminton racket.

Of course, the method of inserting the left half and the right half of the racket frame can be changed, that is, the first section of the badminton thread is inserted into the right half of the racket frame to form the vertical line of the right half of the racket frame; the second section of the badminton thread is arranged on the left half part of the racket frame in a penetrating way to form a vertical line of the left half part of the racket frame, and then the vertical line is arranged on the whole racket frame in a penetrating way to form all transverse lines of the racket frame.

By adopting the badminton racket threading method, each ball line can enjoy independent tension, the pound number of the racket is more accurate, the racket frame can be uniformly stressed, and the hand feeling and the accuracy of the ball falling position during ball hitting are improved.
