The crown portion of thebody 10 is provided with a generallyround crown opening 40. The sole portion of theclub head body 10 is provided with asole opening 50 correspondingly. Thesole opening 50 shares the same axis with thecrown opening 40. Thesole opening 50 and the crown opening are connected via apassage 60. Theclub head body 10 may be designed into different sizes and shapes if required. -
Club shaft 90 may also be designed into different lengths and shapes. One end of theexchangeable hosel 80 is aninsertion end 70 that inserts into thecrown opening 40 of the club head body. The position holding structure may be set as: theinsertion end 70 of the exchangeable hosel is provided with aflange 71 for positioning. Theflange 71 preferably contacts the top portion of thecrown opening 40 of the body to limit the up and down movements of theinsertion end 70 incrown opening 40. Theflange 71 may sink into thecrown opening 40, which contacts the step of thecrown opening 40 to limit the up and down movements of theinsertion end 70 incrown opening 40. Theinsertion end 70 is also provided with arotation detent 72. The position in thecrown opening 40 which corresponds to therotation detent 72 is provided with aslot 42 to embed therotation detent 72. Therotation detent 72 inserts into theslot 42 to limit the circumferential rotation of theexchangeable hosel 80. - The
crown opening 40 may be a counter bore. That is, the diameter of the crown opening is bigger than the diameter of the bottom portion of the crown opening, further; the diameter of the crown opening is bigger than the diameter of the passage. Thecrown opening 40 may also be a through opening, that is, the diameter of the crown opening is smaller than or equal to the diameter of the bottom portion of the crown opening; further, the diameter of the crown opening is smaller than or equal to the diameter of the passage. Thesole opening 50 may be a counter bore. That is, the diameter of the sole opening is bigger than the diameter of the bottom portion of the sole opening; further, the diameter of the sole opening is bigger than the diameter of the passage. The lockingmember 30 is sunk into thesole opening 50. The lockingmember 30 is connected durably with theinsertion end 70. The connection of the durable connection connects with thepassage 60 via theclub head body 10. Preferably, the durable connection is by threads connection, and preferably, the lockingmember 30 is a bolt. Theexternal thread 31 of the bolt is the connection portion of the durable connection.

As is same in the first and second embodiments, the crown portion of theclub head body 10 is provided with a generallyround crown opening 40, while the sole portion of theclub head body 10 is provided with asole opening 50 corresponds to thecrown opening 40. Thesole opening 50 shares the same axis with thecrown opening 40. Thesole opening 50 andcrown opening 40 is connected by a passage. But theposition holding structure 40 for holding the position of the exchangeablehosel insertion end 70 in the crown opening is different from those in the first and second embodiments: aninsertion end 70 is also provided with aflange 71 for preventing theexchangeable hosel 80 from up and down movement, and the limitation of circumferential rotation is realized byinner splines 43 andouter splines 73 between the wall of crown opening 40 of the club head body and theinsertion end 70 of the exchangeable hosel. Theinner splines 43 andouter splines 73 are preferably straight splines along the axis direction of thecrown opening 40. The sectional shape of the splines is rectangle preferably. When hitting the ball to cause impaction, the inner and outer splines joggled with each other, so that the position holding structure is with good durability. Therefore, theinsertion end 70 of theexchangeable hosel 80 is fixed inside thecrown opening 40 of theclub head body 10. Certainly, theinner splines 43 andouter splines 73 can also be bevel splines that joggle with each other, while the sectional shape may also be involute, trapezia etc. The position holding structure between the exchangeablehosel insertion end 70 and the body crown opening in the first and second embodiments may also be set as the inner and outer splines joggling structure in the present embodiment. - In this embodiment, the
sole opening 50 of theclub head body 10 and the passage that connects with the crown opening and thesole opening 50 incorporated to form a throughopening 2. That is, the passage expands downwards to the surface of the sole portion of theclub head body 10. Astep 3 is provided near the throughopening 2 of the sole portion of theclub head body 10. The lockingmember 30 is provided on thestep 3 to connect durably with the exchangeablehosel insertion end 70. The durable connection may be set as the threads connection or other durable connection as inembodiments embodiments -
FIG. 4 is the structure view of the forth embodiment of the present invention. The golf club comprises aclub head body 10, anexchangeable hosel 80 and a lockingmember 30. The crown portion of theclub head body 10 is provided with a generallyround crown opening 40, while the sole portion of theclub head body 10 is provided with asole opening 50 corresponds to thecrown opening 40. Thesole opening 50 shares the same axis with thecrown opening 40. Thesole opening 50 is connected with thecrown opening 40 via a passage. Theclub head body 10 is hollow, thecrown opening 40 is a counter bore, and thesole opening 50 is a through opening. The size of thesole opening 50 is greater than the size of the lockingmember 30, that is, the lockingmember 30 can pass through thesole opening 50 and enter into the cavity of theclub head body 10. The lower portion of thecrown opening 40 is provided with an upper connection opening 41 that connects thecrown opening 40 to the cavity of theclub head body 10. The passage is formed by theupper connection opening 41 and the cavity between thecrown opening 40 andsole opening 50. The crown opening can also be a counter bore opening. That is, the diameter of the crown opening is bigger than the diameter of the upper connection opening that set on the lower portion of the crown opening. At this point, the locking member is fixed on the wall of the lower portion of the crown opening in the club head body. The crown opening can be a through opening also, that is, the wall of the crown opening extends into the cavity of the club head body. At this point, the locking member can be fixed on the end of the wall of the crown opening by a washer or directly fixed on the end of the wall of the crown opening. - One end of the
exchangeable hosel 80 is aninsertion end 70. The positioning holding structure between the insertion end and thecrown opening 40 of the club head body may be the same configuration as inembodiments embodiments insertion end 70 and the lockingmember 30 is different: the lockingmember 30 passes through thesole opening 50 of the club head body, and set on the inner wall of theclub head body 10 that near aupper connection opening 41, to connect durably with theinsertion end 70 of theexchangeable hosel 80. The connection of the durable connection is implemented by the upper connection opening 41 as inembodiments embodiments member 30 may be a nut, and preferably a bolt. - As shown in
FIG. 4 , in the present embodiment, a tapering portion that cooperates with each other is set between theinsertion end 70 of the exchangeable hosel and thecrown opening 40 of the club head. While assembling, theexchangeable hosel 80 may insert into thecrown opening 40 easily, which makes the assembling quicker. The same tapering portion may also be applied inembodiments - When the tapering portion cooperates with the positioning holding structure between the
insertion end 70 of the exchangeable hosel and thecrown opening 40 of the club head body, the fifth embodiment of the present invention is constructed. As shown inFIG. 5 , at this point, the rotation detent structure of the circumferential rotation between thecrown opening 40 of the club head body and theinsertion end 70 of the exchangeable hosel is the inner and outer splines structure in the third embodiment. Theinner splines 43 and theouter splines 73 are taperingsplines 5 that joggle with each other. The tapering splines 5 may limit the circumferential rotation of theinsertion end 70 of the exchangeable hosel inside thecrown opening 40 of the club head body. It may also direct theexchangeable hosel 80 to insert into thecrown opening 40 easily. - In the first to fifth embodiments of the present invention, one end of the
exchangeable hosel 80 is theinsertion end 70 of the exchangeable hosel. The other end which shares the same axis with insertion portion of the exchangeable hosel fixes on one end of theclub shaft 90 by adhesive connection.
