Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment 1:

[0032] Please refer to Figures 1 - 3 , a composite material golf ball head, the structure of which includes a club 1, a golf ball head 2 and a connection cylinder 3. The bottom of the club 1 is connected to the golf ball head 2 through the connection cylinder 3, and the connection cylinder 3 and the golf ball head 2 are of an integrated structure.

[0033] In this embodiment, the golf ball head 2 is forged from titanium alloy material.

[0034] In this embodiment, a striking face 21 is compound-welded onto the golf club head 2. The striking face 21 is cast from aluminum alloy and inlaid with a stainless steel plate. By combining the advantages of high strength, corrosion resistance, and light weight of the aluminum alloy material with the high strength and long service life of the stainless steel, the striking face 21 on the golf club head 2 can be better used, increasing the service life and usage effect of the striking face 21.

[0035] In this embodiment, a top cover 22 is compound-welded onto the side of the golf club head 2 away from the striking face 21. The top cover 22 is made of magnesium alloy. By virtue of the advantages of light weight, high strength, and strong shock absorption performance of the magnesium alloy material, the golf club head 2 can reduce the transmission of vibration during hitting when in use, protecting the user's arm.

[0036] Working principle: This golf club head 2 has a striking face 21 that is compound-welded and cast from aluminum alloy and inlaid with a stainless steel plate. By combining the advantages of high strength, corrosion resistance, and light weight of the aluminum alloy material with the high strength and long service life of the stainless steel, the service life and usage effect of the striking face 21 can be increased. Then, a top cover 22 made of magnesium alloy is compound-welded onto the back of the golf club head 2. Due to the advantages of light weight, high strength, and strong shock absorption performance of the magnesium alloy material, the golf club head 2 can reduce the transmission of vibration during hitting when in use, protecting the user's arm.

[0037] Embodiment Two:

[0038] Please refer to Figures 4 - 8 , a composite material golf club head of the present utility model. Compared with Embodiment One, this embodiment further includes: The connecting tube 3 includes a through hole 31, a clamping groove 32, and a chamfer 33. A through hole 31 that penetrates the connecting tube 3 is provided on the connecting tube 3. A plurality of clamping grooves 32 are symmetrically provided on the inner wall of the connecting tube 3, and chamfers 33 are provided at both ends of the clamping groove 32.

[0039] In this embodiment, the golf club 1 includes a positioning member 11, a stopper 12, an installation groove 13, a rotating shaft 14, and a round hole 15. A round hole 15 is provided on the golf club 1, and a positioning member 11 is slidably fitted in the round hole 15. A plurality of installation grooves 13 are symmetrically provided on the golf club 1, and a rotating shaft 14 is installed in each installation groove 13. A stopper 12 is rotatably fitted on the rotating shaft 14, and the area of the installation groove 13 is larger than that of the stopper 12, capable of completely accommodating the stopper 12.

[0040] In this embodiment, the diameter of the round hole 15 is the same as that of the through hole 31, and when the golf club 1 is inserted into the connecting tube 3, the round hole 15 and the through hole 31 are on the same horizontal line.

[0041] In this embodiment, the positioning member 11 includes a plug 111, an external thread 112 and a fixing ring 113. One end of the plug 111 is provided with an external thread 112, and the plug 111 can be threadedly connected to the fixing ring 113 through the external thread 112 to fix the golf club 1 and the connecting cylinder 3.

[0042] In this embodiment, arc chamfers 121 are provided on both sides of the stopper 12. A rotation hole 122 that is rotationally matched with the rotating shaft 14 is provided on the stopper 12. A spring 123 is installed on one side of the stopper 12 close to the installation groove 13, and the other end of the spring 123 is connected to the installation groove 13.

[0043] Working principle: When the golf club head 2 is installed and used, the golf club 1 is inserted into the connecting cylinder 3 at the top of the club head. Then, the golf club 1 is rotated so that multiple groups of stoppers 12 installed on both sides of the golf club 1 are opposite to the engaging grooves 32 in the connecting cylinder 3. At this time, after the stoppers 12 lose the extrusion force of the connecting cylinder 3, they will be pushed out by the elastic force of the spring 123. The stoppers 12 rotate out under the rotation of the rotating shaft 14 and will be engaged with the engaging grooves 32, thereby fixing the golf club 1 and the connecting cylinder 3, so that the golf club 1 will not move up and down in the connecting cylinder 3. Then, the positioning member 11 is inserted into the through hole 31 and the round hole 15, and then the plug 111 is fixed through the threaded connection between the fixing ring 113 and the plug 111, so that the golf club 1 and the connecting cylinder 3 are fixed, and the golf club 1 will not rotate in the connecting cylinder 3, which is convenient for the installation and disassembly between the golf club head 2 and the golf club 1, so that the golf club head 2 can be replaced;

[0044] When it is necessary to disassemble the golf club head 2, after loosening the fixing ring 113, the positioning member 11 is removed from the golf club 1. Then, the golf club 1 is rotated. Through the cooperation of the arc chamfers 121 on both sides of the stopper 12 and the inclined chamfers 33 on both sides of the engaging groove 32, the stopper 12 can be moved out of the engaging groove 32 when the golf club 1 rotates and will come into contact with the inner wall of the connecting cylinder 3 again. Through the pressure exerted by the inner wall of the connecting cylinder 3 on the contact of the stopper 12, the stopper 12 is squeezed back into the installation groove 13 again, and then the golf club 1 is pulled out upward, so that the golf club head 2 can be replaced and maintained.
