AI Technical Summary
Existing string tension testing devices have a limited range of applications, are cumbersome to operate, are not suitable for stringed instruments such as guitars, violins, and guzheng, and are inconvenient to use.
A string tension detection device was designed, comprising an adjustment component, a transmission component, and a bubble level. The device drives the connecting frame to move via an adjustment disc and a threaded connection, adapting to the tension requirements of different musical instruments. The transmission block is designed with an arc-shaped groove and a protrusion structure to accommodate different string diameters. A limit block and support rod stabilize the device, the bubble level is quickly calibrated, and the pressure sensor automatically collects data.
The device's applicability has been expanded, the operation process has been simplified, and the convenience and accuracy of testing have been improved. It is suitable for a variety of stringed instruments and requires no additional fixed carrier or manual reading.
