Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wire protection nails, in particular to a badminton racket single grain nail. BACKGROUND

[0002] The badminton racket single grain nail is a small metal or plastic piece installed at the badminton racket string hole, mainly to protect the edge of the badminton racket string hole from being cut by the net string, prolong the service life of the badminton racket, and also help to maintain the stability and performance of the badminton racket. In addition, the single grain nail can also ensure the correct position and tension of the badminton racket string during threading.

[0003] Chinese patent publication No. CN221412169U discloses a single grain nail structure of a racket, comprising a nail body head, a nail body connecting part, and a threading hole. The utility model integrally forms the nail body connecting part at the bottom of the nail body head, and a threading hole for passing through the racket net string is provided inside the nail body head and the nail body connecting part. Two wire clamping grooves located on the same straight line are arranged in the convex ring on the top side of the nail body head, which facilitates clamping and positioning of the racket net string and prevents the net string from being worn when accidentally touching the ground. The reinforcing block is installed in the hollow middle part of the racket annular frame, and the supporting block abuts against the inner side of the racket annular frame to improve the stability of the pipe body installation, thereby improving the overall structural strength of the single grain nail structure and improving the practicality.
