Abstract
A self-releasing and self-locking string locking mechanism for adjusting a string includes a fixed seat mounted on a stringed instrument, a worm shaft, a worm gear, a rotating shaft and a sleeve. The worm shaft drives and rotates the worm gear, and is installed on the fixed seat. The rotating shaft, pivotally connected on the fixed seat and secured on the worm gear, includes a self-releasing thread having a pitch thread between 1.25 mm and 1.6 mm and applied with a lubricant, and a locking pin. The sleeve is for the locking pin to be inserted therein, and internally includes an inner thread corresponding to the self-releasing thread and a lower surface for the locking pin to abut against. The sleeve is further provided with a through opening for the string to pass through near the lower surface.
