Abstract
A string adjustment apparatus includes an outer shell, an adjustment stem member, a winding shaft member and a base. The outer shell includes a housing recess and a recess opening. The adjustment stem member includes a stem and a turning peg. The winding shaft member includes a shaft, a worm gear portion and a string hole portion. The base includes a plate corresponding to the recess opening and a first tube extended from the plate towards a direction remote from the outer shell. The worm gear portion and the stem are located in the housing recess and coupled with each other. The shaft runs through the first tube to make the string hole portion to pass through the first tube and also make the plate to cover the recess opening. Thus, a simpler structure is formed to make assembly easier.
