Badminton racket and its handle

This creation is about a badminton racket, especially about the grip of a badminton racket.

The badminton competition is a common and popular ball sport. The hitter uses badminton racket to fight badminton as a competition. The main structure of the badminton racket includes a frame, a middle tube and a grip, and the frame and the handle are connected by a middle tube. In general, the grip of a badminton racket can be divided into a wooden grip and an artificial grip depending on the material, and the artificial grip is often made of carbon fiber.

When hitting the ball, a wooden handle can be used to achieve a better hand feeling, hereinafter referred to as a hitting feeling. However, the weight of the wood is unstable, and the yield is also unstable, and it is easy to have a shortage of materials. Therefore, the artificial grip is born. At present, the most common artificial grip is made of carbon fiber, and in order to achieve a lightweight effect, the frame, the middle tube and the grip are formed in one piece. Since the middle tube and the grip are integrally formed, the performance of the middle tube cannot be exerted, the hitting feeling is deteriorated, and the structural strength is poor.

Therefore, there is a need for a badminton racket with an artificial grip to solve the problem of the weight of the wood faced by the wooden grip, the unstable production, and the fact that the artificial grip cannot exert the performance of the middle tube, thereby deteriorating the hitting feeling and structural strength. Poor question.

In view of the above problems, the main purpose of the present invention is to provide a badminton racket and a grip thereof, which can be solved by inserting a fixing member inside the grip and allowing the middle tube to be inserted from the opening of the front sleeve to the fixing member. The artificial grip cannot exert the performance of the middle tube, which in turn deteriorates the hitting feeling and the structural strength is poor.

To achieve the above object, the present invention provides a badminton racket that includes a frame, a middle tube, and a handle. One end of the middle tube is connected to the frame, and the handle is connected to the other end of the middle tube. The handle includes a front sleeve, a hollow portion and a fixing member. The front sleeve is located at the front end of the handle and has an opening. The hollow portion is located inside the grip. The fixing member extends from the opening to the hollow portion, wherein the middle tube is inserted from the opening to the fixing member.

In order to achieve the above purpose, the present invention further provides a grip connected to one of the tubes of a badminton racket. The handle includes a front sleeve, a hollow portion and a fixing member. The front sleeve is located at the front end of the handle and has an opening. The hollow portion is located inside the grip. The fixing member extends from the opening to the hollow portion, wherein the middle tube is inserted from the opening to the fixing member.

According to an embodiment of the present invention, the fixing member has a bottom portion, and the middle tube has a predetermined distance from the bottom portion.
