However, when the golf club is actually used, the installation process of the club head connected by bolts and nuts is cumbersome, which is inconvenient for users to assemble or disassemble, and increases the installation time of users. In addition, when hitting the golf ball, the club head will be subjected to a large force and often subjected to impact and vibration. Since the bolts and nuts are threaded connections and may loosen, the club head will shake, making it difficult to control the hitting position of the club head when hitting the ball. Therefore, it is of great significance to study detachable golf clubs to solve the above problems. Utility Model Content
