Benefits of technology

"The present invention provides a golf club head with adjusting grooves that can relieve stress concentration during angle adjustment, reducing the occurrence of wrinkles, structural deformation, or residual stress concentration. The adjusting grooves can be formed around the peripheral surface of the neck portion or the hosel, and can be a plurality of square grooves or other shapes. The depth of the adjusting groove is based on the yield strength of the golf club head, and does not affect the structure security of the golf club head. The angle adjustment of the golf club head becomes easier and does not need to be done by a professional club adjuster."

Problems solved by technology

However, after the angle adjustment, the club head is susceptible to forming wrinkles, residual stress concentration or other defects caused by external force applied, especially on the area between the hosel of the golf club head and the neck portion of thereof, thus greatly affecting the structural security and appearance of the golf club head, further influencing the striking efficacy and stability of the golf club.
