The fine tuning handle of piano, including adjusting rod, described adjusting rod one end are provided with handle, the setting of the adjusting rod other end
There is adjusting head, adjusts centriciput and offer the first matching hole, be provided with square block in the middle part of the adjusting rod, square block outer surface is set
It is equipped with connecting rod, and is in 90 ° between connecting rod and adjusting rod, the connecting rod outer surface is provided with fixing seat, and the connecting rod bottom end is fixed
Seat middle part is provided with the second matching hole.
The adjusting rod includes shell, and the shell integrated disc portions inner wall is provided with worm gear, and the shell cylindrical parts are set
It is equipped with worm screw, and the gear teeth of worm gear and worm wheel tooth engagement, the worm screw stretches out cylindrical parts and handle is fixedly mounted, the snail
Wheel middle part is provided with fixing axle, and fixing axle stretches out shell integrated disc portions and adjusts head and is fixedly mounted.
It is fixedly mounted between the connecting rod and square block by holding screw, passes through tightening between the connecting rod and fixing seat
Screw is fixedly mounted.
The length and width of first matching hole are 6.5mm.
Beneficial effects of the present invention, apparatus of the present invention structure is simple, and manufacturing cost is low, convenient and practical, while being suitable for industry
Remaining fan and professional；Apparatus of the present invention drive worm gear rotation by handle rotary worm, worm screw rotation of the present invention
Worm gear rotates a tooth within one week, realizes to the fine adjustment of concrete-steel silk string, avoids paino wire string excessive or excessively loose, influence piano
Using effect.
