Fine piano tuning handle

Abstract

The invention discloses a fine piano tuning handle, and belongs to the technical field of auxiliary adjusting tools of musical instruments. The fine piano tuning handle comprises an adjusting rod, wherein a handle is arranged at one end of the adjusting rod; an adjusting head is arranged at the other end of the adjusting rod; the middle part of the adjusting head is provided with a first matchinghole; a square block is arranged on the middle part of the adjusting rod; the outer surface of the square block is provided with a connecting rod; an angle of 90 degrees is formed between the connecting rod and the adjusting rod; the outer surface of the connecting rod is provided with a fixing base; a second matching hole is formed in the middle part of the fixing base at the bottom end of the connecting rod. The fine piano tuning handle is simple in structure, is low in manufacturing cost, is convenient and practical, and is suitable for hobbyist and professional. A worm is driven to rotatethrough the handle in order to drive a worm gear to rotate. When the worm rotates for one circle, the worm gear rotates for one tooth, so that the fine adjustment for piano is realized, and the influence of over-tightness or over-looseness of the strings on the using effect of the piano is avoided.
