Abstract

A golf club has a shaft, a connecting pin, a pin and a nut. One end of the connecting pin is securely inserted into the shaft, the other end of the connecting pin is threaded and is exposed from the shaft. The head is mounted on the shaft and has a neck with a passage for the shaft inserting into the passage in the neck. A baffle formed in the passage in the neck and has a through hole for the connecting pin extending through the through hole. The nut is screwed with the thread on the connecting pin and abuts the baffle. Consequently, the head is securely attached to the shaft with the connecting pin and the nut. With such an arrangement, the head is adjustable relative to the shaft prior to an adhesion process.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A golf club comprising: 
 a shaft with a first end and a second end, and a grip formed on the first end;    a connecting pin having a first end securely inserted into the second end of the shaft and a second end with thread exposed from the second end of the shaft;    a head mounted on the second end of the shaft and having a neck with a passage for the second end of the shaft inserting into the passage in the neck;    a baffle formed in the passage in the neck and having a through hole defined through the baffle for the second end of the connecting pin extending through the through hole; and    a nut screwed with the thread formed on the second end of the connecting pin and abutting the baffle to securely attach the connecting pin to the neck of the head, wherein before the shaft is fixed relative to the head, the head is rotatable relative to the shaft.    
     
     
         2 . The golf club as claimed in  claim 1 , wherein a flange is formed on the connecting pin near the second end of the connecting pin and abuts the bottom of the shaft to position the head relative to the shaft.  
     
     
         3 . The golf club as claimed in  claim 2 , wherein a thread is formed on the connecting pin at one side of the flange far away from the second end of the connecting pin; and 
 an inner thread is formed on an inner surface of the second end of the shaft to screw with the first thread on the connecting pin.    
     
     
         4 . The golf club as claimed in  claim 1  further comprising a ferrule secured on the shaft to abut the top of the neck so as to position the head relative to the shaft.  
     
     
         5 . The golf club as claimed in  claim 1  further comprising a layer of glue arranged between the neck and the shaft to increase fixation between the head and the shaft.  
     
     
         6 . The golf club as claimed in  claim 1  further comprising an elastic material applied in the second end of the shaft and surrounding the first end of the connecting pin to secure the connecting pin to the shaft.  
     
     
         7 . The golf club as claimed in  claim 6  further comprising a plug received in the shaft to keep the elastic material from filling in entire shaft.  
     
     
         8 . The golf club as claimed in  claim 6 , wherein at least one groove is defined in an outer surface of the connecting pin to receive the elastic material.  
     
     
         9 . The golf club as claimed in  claim 6 , wherein at least one bore is defined in the shaft for excess of the elastic material discharging from the at least one bore as the connecting pin is inserted into the shaft.
