That is, the first link 3221 and the second link 3222 are relatively rotatable, so that the driving rod 321 is movably connected to the frame 10 and can move linearly with respect to the frame 10.

Specifically, the second link 3222 is formed with the handle portion 322a and the range-limiting portion 322b, i.e., the driving rod 321 is driven to perform linear motion and the first link 3221 is driven to perform rotational motion by rotating the handle portion 322 a.

In another embodiment, the driving rod 321 is provided with a stroke port along the length extending direction thereof; one end of the rotating rod 322 is rotatably connected with the fixed rod 323, and the other end of the rotating rod 322 is limited in the stroke opening and moves along the extending path of the stroke opening. When the rotating rod 322 moves along the extending path of the stroke opening, the included angle between the rotating rod 322 and the driving rod 321 changes, and the supporting height of the rotating rod 322 relative to the driving rod 321 changes along with the change of the included angle, that is, the linear motion of the driving rod 321 is ensured by changing the supporting height of the rotating rod 322 relative to the driving rod 321.

Referring to fig. 2, the frame 10 includes an upper-row peg 20 plate 11, a lower-row peg 12, a pillar 13, a partition pillar 14, and a cavity plate 15; the first end of the upper chord 20 plate 11 is connected with the first end of the lower chord 12 plate; the first end of the upright column 13 is connected with the second end of the upper-row peg 20 plate 11, and the second end of the upright column 13 is connected with the second end of the lower-row peg plate 12; the first end of the separation column 14 is connected with the first end of the upper row chord shaft 20 plate 11, and the second end of the separation column 14 is connected with the middle part of the upright column 13; therefore, the upper chord 20 plate 11, the upright column 13 and the partition column 14 surround together to form the first opening 10a, the lower chord 12 plate, the upright column 13 and the partition column 14 surround together to form the second opening 10b, the number of the cavity plates 15 is two, and the two cavity plates 15 cover both ends of the second opening 10b to form the resonance cavity.

Specifically, the upper chord 20 is mounted on the upper chord 20 plate 11, the lower chord is mounted on the lower chord plate 12, and the pitch mechanism 30 is disposed on the upper chord 20 plate 11 and between the upper chord 20 and the lower chord.

In an embodiment, referring to fig. 1-3, the konghou 100 further includes a buffer rod 40 fixed on the plate 11 of the upper chord 20 and located between the upper chord 20 and the pitch-adjusting mechanism 30, and after the string is led out from the upper chord 20, the string is wound around the buffer rod 40 and then passes through the moving rod assembly 31 to buffer the traction of the string.

In some specific embodiments, the peripheral side of the buffer rod 40 is formed with a first annular groove 41, and the first annular groove 41 is used for limiting the passing direction and the passing range of the string relative to the buffer rod 40.

Referring to fig. 3, the upper row pin 20 plate 11 is further formed with positioning holes; the konghou 100 further comprises a positioning cylinder 51 and a fixing piece 52, the positioning cylinder 51 is fixed in the positioning hole, and a first fixing hole is formed in the positioning cylinder 51 in a penetrating mode; the upper row tuning peg 20 has a first fixing portion for fixing the strings and a second fixing portion for extending into the positioning tube 51, and a second fixing hole is formed on the second fixing portion, the fixing member 52 sequentially passes through the first fixing hole and the second fixing hole, and the upper row tuning peg 20 is mounted on the musical instrument frame 10.

The structure of the lower chord can be referred to the structure of the upper chord 20, and will not be described herein.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims. The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
