Abstract
A racket stringing machine utilizing an improved retaining standard for securing a racket to be strung in a fixed position. The retaining standard includes a vise portion and a clamp portion. The clamp portion has an attached rod that fits into a hole in the vise. The clamp portion serves to maintain the racket to be strung in a fixed position on the vise. The vise also includes a slot into which a dog is inserted. The dog bears against the clamp rod and fixes it in a particular location. A handle having a cam portion is also provided. The cam portion of the handle engages the dog so as to allow selective engagement with the clamp rod. Additionally, frame retainers of different sizes and shapes are provided that allow rackets of various configurations to be strung with the same stringing machine.
