Embodiment

[0036] see Figure 1-3 , The invention provides an adjustable piano strike point positioning tool for positioning the height position and depth position of an upright piano strike point. The detection tooling includes a bottom resting plate 1 , a movable slider 3 , a first locking member 4 , a movable caliper guide rail 5 , a movable caliper 6 and a second locking member 7 .

[0037] Such as Figure 1-2 As shown, the bottom resting plate 1 is a rectangular parallelepiped arranged longitudinally, and is used to abut against the middle panel of the piano during measurement. The movable slider guide rail 2 arranged along the lengthwise direction is installed above it. The movable slider guide rail 2 includes two limit strips 21 respectively extending to the front end of the bottom resting plate, and the two limit strips are fixed on the left and right sides of the movable slider to limit the moving direction of the movable slider and Prevent the movable slider from breaking away
