Each fine adjuster includes a string hook, a hook support, a double-thread sleeve, an external-screwing nut and a fine-adjustment screw. Each string hook is in the shape of an inversed L and includes a hook body and a hook handle. The hook bodies are hinged at the upper parts of the hook supports through hinge pins. One side of the bottom of each hook support is provided with the double-thread sleeve. The metal part of the substrate is provided with installation holes which match the double-thread sleeves. The external-screwing nuts are installed at the outer sides of the double-thread sleeves.
