[0031] Reference Figure 3 and Figure 4When the rear Yueshan 15 needs to be installed, the locking mechanism 5 is first aligned with the installation groove 113, so that the receiving dew 18 is clamped in the installation groove 113, and the locking mechanism 5 passes through the installation groove 113. The first locking rod 51 and the second locking rod 53 have a certain elasticity. When the receiving dew 18 is pressed, the two second locking rods 53 can be deformed in the direction facing each other, so that the second locking rod 53 and the second locking rod 53 can enter the fixing groove 131. When the receiving dew 18 conflicts with the groove bottom of the installation groove 113, the second locking rod 53 restores its original shape under the action of its own elasticity and contacts the groove wall of the fixing groove 131. 2 and the second locking block 54 descend, the reinforcing rod 632 and the positioning rod 61 are squeezed, so that the positioning spring 62 is compressed, and then the positioning rod 61 can be driven to retract into the slide groove 132. When the bearing 18 is installed in place, and under the action of the positioning spring 62, the end of the positioning rod 61 is extended and abuts against the upper end surface of the first locking block 52, so that the first locking block 52 and the positioning rod 61 are interlocked. In addition, when the positioning rod 61 is extended, it drives the reinforcement rod 632 to extend in the direction close to the second locking block 54, so that the end of the reinforcement rod 632 is inserted into the card slot 55, forming a double lock, thereby improving the installation stability of the rear mountain 15.

[0034] The working principle of the embodiment of the present application is: the first string 2 and the second string 3 are set, and the fusion of different temperament systems is realized through the combination of frets and no frets. Specifically, the five first strings 2 correspond to a row of frets 111, and the four second strings 3 correspond to frets 112. It can be like the guqin, according to the effect of the overtones played by the frets 111, satisfying the various techniques of the guqin such as wiping, picking, hooking, picking, hitting, and picking, moving back and forth on the first string 2 to cut the string, and it can also play a fixed pitch by pressing the frets on the second string 3. The nine-string zither of the present application can realize the playing method of double plucking of the right hand. That is, when the left hand cuts the strings, the right hand plucks the strings. When the left hand presses the fixed fret 112, the right hand can also pluck the strings, achieving the playing method of double plucking, solving the problem that single plucking cannot solve, greatly enriching the playing techniques, being able to produce different timbres, and greatly expanding the range of sound. At the same time, it can also satisfy the pitch changes within semitones, and the timbre changes are rich.
