This embodiment is provided to more completely explain the present invention to those of ordinary skill in the art.

Accordingly, the shape of the components expressed in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same components in each drawing are sometimes illustrated with the same reference numerals. In addition, detailed descriptions of functions and configurations of known technologies that may unnecessarily obscure the gist of the present invention may be omitted.

First, a configuration of a length-adjustable sports racket according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6 .

In the sports racket in this embodiment, a circular head part 20 provided with an elastic mesh 21 in the form of a net is configured on one side of the shaft part 10 forming a predetermined length, and the shaft part 10 is A badminton racket having a grip portion 30 for a handle is formed on the other side.

In particular, in the present invention, one end of the shaft portion 10 is inserted into the grip portion 30 to form a guide groove 31 for guiding so that the length can be adjusted, and the grip portion 30 has the shaft portion 10 . A control button 40 for adjusting fixing or insertion is provided, and the shaft portion 10 inserted into the guide groove 31 is made of a metal material and a guide long hole 11 of a certain length is formed through, The long hole 11 is provided with a magnet block 41 having a magnetic force.

At this time, the magnet block 41 forms a structure connected by the control button 40 and the connecting rod 42 , the magnet block 41 is elastically supported by the first elastic spring 43 inside, and the guide A second elastic spring 32 for elastically supporting the shaft portion 10 is configured in the groove 31 .

On the other hand, the control button 40 forms a flat surface of the same height as the grip part 30 to prevent external protrusion, and the guide long hole 11 and the magnet block 41 can make surface contact in the form of a predetermined inclined surface. It can be seen that the cross-sectional structure of the trapezoidal shape is formed so that the grip portion 30 is provided with a locking protrusion 33 for preventing the control button 40 from being separated.

In addition, it is preferable that a guide part (not shown) is provided inside the guide groove 31 to guide the linear flow of the magnet block 41 by interlocking with the adjustment button 40 .

In addition, as shown in the enlarged view of FIG. 1 on the surface of the control button 40, a trademark may be printed or a sticker attached method may be configured to improve visibility and appearance.

Let's take a look at the effect of the length adjustment operation of the sports racket of the present invention having such a configuration.

The sports racket in this embodiment can be adjusted and used according to the user's body characteristics through the length adjustment function, and the space occupied during storage can be minimized.
