The characteristics of the club body 12 can be adjusted according to the actual situation of the club 1 to meet different hitting needs. However, generally, the locking member 13 is locked in a direction perpendicular to the axis line of the rod body 12 as shown in FIG. 1 (that is, the angle between the locking member 13 and the axis line of the rod body 12 is 90 degrees). Or as shown in FIG. 2, the locking is performed along the radial direction of the rod body 12 (that is, the angle between the axis of the locking member 13 and the rod body 12 is 0 degrees), and the foregoing two are generated through the locking respectively. The forward force in the axial direction and the radial direction of the rod body 12, but this locking method has only a one-way forward force and has a problem of insufficient stability, so there is still room for improvement.

In addition, when the golf club 1 of FIG. 1 is locked, the lock hole of the club body 12 needs to be aligned with the lock hole of the club head 11, but the club head 11 only abuts against the club body 12 with the top edge. When the lever body 12 is too long due to tolerances, the lock hole of the lever body 12 will be located below the lock hole on the club head 11, causing the two to deviate, resulting in an error in the lock setting, and then affecting the tightness of the joint. Sex. On the other hand, in order for the golf club 1 in FIG. 2 to have sufficient space for the locking member 13 to move in the axial direction of the shaft 12, a part of the bottom of the club head 11 needs to be excavated for the purpose. The locking member 13 is inserted and passed. This design will greatly affect the structure of the golf club 1 and make its reverse effect greatly reduced.

Therefore, it is an object of the present invention to provide a golf club that is interchangeable and has high joint stability.

Therefore, the golf club of the present invention includes a club head, a club body detachably inserted on the club head, and a club head and the club body to pass through the club head to detachably fix the club body. A fixing member on the club head. The axis line of the fixing member intersects the axis line of the rod body, and an acute angle is interposed therebetween.

The effect of the present invention is that the fixing member detachably locks the rod body to the head in an oblique manner, so that the fixing member and the axis line of the rod body set an acute angle, compared with the conventional method. The golf club with an included angle of 0 degrees can additionally provide a radial fixing force and keep the fixing member away from the bottom of the club head without affecting the reverse effect of the shot. Compared with the conventional golf ball with an included angle of 90 degrees, For a golf club, the present invention can provide an axial fixing force, thereby increasing the stability of locking and improving the problem of insufficient stability of the conventional golf club.

Referring to FIG. 3, an embodiment of a golf club 2 according to the present invention. It should be noted that the directions of up and down and horizontal referred to in the following description are defined by the direction in which a general user holds the golf club 2 normally. For easy explanation. The golf club 2 includes a club head 3, a club body 4 detachably inserted downwardly on the club head 3, and a screw threaded through the club head 3 and the club body 4 in an oblique direction. Securing member 5.

The head 3 includes a ball striking portion 31 surrounding an inner space 310, and a club seat portion 32 connected to the ball striking portion 31 and defining an insertion hole 320. The insertion hole 320 extends in the up-down direction and communicates with the inner space 310. The rod seat portion 32 has an inner inclined surface 322 located in the inner space 310 and defining a through hole 321. The axis line A of the through hole 321 and the axis line B of the insertion hole 320 intersect but are not perpendicular to each other.

The shaft body 4 includes a shaft portion 41 extending in the up-down direction and held by a user, and a shaft sleeve portion 42 detachably disposed at the bottom end of the shaft portion 41 and inserted into the insertion hole 320. And an extending portion 43 extending downward from the rod sleeve portion 42 and extending into the inner space 310. The extending portion 43 has an outer inclined surface 432 forming a through hole 431 and facing the inner inclined surface 322. The through hole 431 is coaxially aligned with the through hole 321. The inner inclined surface 322 and the outer inclined surface 432 are parallel to each other. The extending portion 43 forms an internal thread that is located in the through hole 431 and can be locked by the fixing member 5.

The fixing member 5 passes through the through hole 321 and the through hole 431 obliquely and upwardly to lock the rod body 4 on the head 3. The axial line A of the fixing member 5 intersects the axial line B of the rod body 4, so that an included angle θ of not more than ninety degrees is set. The included angle θ is an acute angle and is 20 degrees to 70 degrees. In this embodiment, the included angle θ is preferably 60 degrees. The inner inclined surface 322 and the outer inclined surface 432 are parallel to each other, so that the axis line A of the fixing member 5, the through hole 321, and the perforation 431 are located on the same extension line, and the inner inclined surface 322 and the outer surface The normal of the inclined surface 432 extends in the same direction, so that the included angle θ can maintain an acute angle.

The head 3 and the rod body 4 are obliquely locked through the fixing member 5 so that the forward force F generated by the fixing member 5 extends along the axis A of the fixing member 5 and can be horizontally (here referred to as The radial direction of the shaft portion 41) and the up-and-down direction (here, the axial direction of the shaft portion 41) generate two positive component forces F1 and F2, compared with the conventional golf club with an included angle of 0 degrees This embodiment can additionally provide a radial fixing force and keep the fixing member 5 away from the bottom of the club head 3. In addition, the space required to be opened in the club head 3 can be greatly reduced, so as not to affect the impact of the ball. The reverse effect, compared with the conventional golf club with an included angle of 90 degrees, this embodiment can provide an axial fixing force. When the club body 4 is too long due to tolerances, the inner inclined surface 322 of the club head 3 It will resist the inclined surface 432 outside the rod body 4 to achieve positioning and improve the accuracy of the locking. This can improve the locking force of the fixing member 5 and make the rod body 4 more stably fixed to the head 3 On the other hand, when the rod body 4 needs to be replaced, the rod sleeve portion 42 can be taken out of the insertion hole 320 only by unscrewing and pulling away the fixing member 5 to achieve rapid The effect of changing rods.

In summary, the design of the oblique locking of the fixing member 5 can generate positive component forces F1 and F2 in the horizontal direction and the up-down direction, thereby improving the combination stability, and at the same time, it can also be used for users to quickly change the lever and improve the pan.
