The user presses his finger on the positioning shaft 3, which can effectively realize the positioning of the pitch on the position, making it convenient for the user to practice and use the erhu, and is conducive to adjusting each positioning shaft 3 to different positions on the support plate 1, thereby facilitating the adjustment of the position.

[0028] Reference Figure 1 , 4 And 6, this positioning device also includes a stopper 6, a positioning block 7 and a clamping plate 8. A positioning block 7 is arranged at one end of the support plate 1, and a positioning groove corresponding to the positioning block 7 is arranged on the stopper 6. Two clamping plates 8 are symmetrically arranged on both sides of the stopper 6. Through the setting of the positioning groove on the stopper 6, it is convenient to connect with the positioning block 7 to limit the position of the stopper 6 and the clamping plate 8. When in use, the stopper 6 and the clamping plate 8 are separated so that one end of the support plate 1 can pass through the jack position on the erhu (the jack is a device on the erhu used to fix and limit the strings, usually made of cotton thread, silk thread, organic glass, plastic and other materials), and then the stopper 6 and the positioning block 7 are matched so that the clamping plate 8 and the clamping plate 1 5 connect the support plate 1 and the stopper 6 with the erhu, which is convenient for connecting the support plate 1 and the erhu rod body, further improving the position of the connection, reducing the influence of the jack on the installation position of the support plate 1, and the position of the jack can be used to limit the position of the support plate 1.
