A guitar machine head string lock function includes a worm gear, a worm, a string post and a base. The worm gear and the string post are formed in an integrated manner, and are pivotally coupled on the base through a latch element. Assembly is simple and convenient and can achieve precise coupling. The worm is pivotally mounted on the base to engage with the worm gear and has a tuning peg to enable users to turn the worm gear and the string post to adjust the tension of a guitar string.
