1. Field of the Invention
The present invention relates to a golf club interchanging connection structure, and more particularly to an interchanging connection structure for interchanging a club head and a shaft of a golf club.
2. Related Art
As the golf sport develops vigorously, the structure and material of the golf club have also developed accordingly. In order to cater to each golfer, and to enable the golfer to select a suitable combination of a club head and a shaft according to the specific state during striking, golf-club manufacturers exert their efforts in developing a golf club with a quick head-shaft interchanging function.
Referring to FIG. 1, it is a schematic view of a conventional golf club interchanging connection structure. In U.S. Pat. No. 7,083,529, a golf club 10 with a quick interchanging function is proposed, which includes a club head 12 and a shaft 14, and the club head 12 and the shaft 14 are interchanged quickly through an interchanging connection structure 16. The interchanging connection structure 16 includes a club sleeve 18, a tube seat 20, and a screw 22. One end of the club sleeve 18 has an opening 24, the shaft 14 is placed into the opening 24 and bonded in the club sleeve 18. The tube seat 20 is embedded into the club head 12 and bonded in the club head 12. After the club sleeve 18 is placed into the tube seat 20, the screw 22 is used to lock the club sleeve 18 to the tube seat 20, so as to quickly interchange the club head 12 and the shaft 14.
However, when the internal portion of the tube seat 20 becomes deformed since the club head 12 is influenced by the outside force, such as collision, the club sleeve 18 may be hard to be placed into the tube seat 20. Since the tube seat 20 in the conventional art is embedded in the club head 12 and fixed by bonding, it will be very difficult to repair or replace the tube seat 20.
