A small cylinder inner chamber and a large cylinder inner chamber which are communicated are coaxially formed in a cylinder body, the small cylinder inner chamber is communicated with the upper end surface of the cylinder body, the large cylinder inner chamber is communicated with the lower end surface of the cylinder body, the lower end of a rotary rod is rotationally inserted in the cylinder body, a string penetration hole is formed in the upper end of the side wall of the rotary rod, a positioning wheel is arranged in the large cylinder inner chamber, teeth are manufactured on the circumferential surface of the positioning wheel, the positioning wheel is coaxially and fixedly connected with the lower end surface of the rotary rod, a positioning groove is formed in the upper surface of a bottom plate, the upper surface of the bottom plate is fixedly connected with the lower end surface of the cylinder body, a fastening tube is provided with an external thread and coaxially fixed on the upper end surface of the cylinder body, a fastening cap is in fastening connection with the fastening tube through threads, and an opening I and an opening II are formed in the side wall of the fastening cap. A piano string mounting position is fixed in a wrapping and fastening manner, the structure is novel and practical, and string replacement and tuning are more convenient.

Description

technical field [0001] The invention relates to a piano string locking device, in particular to a piano string locking nail which is convenient for string changing and tuning. Background technique [0002] At present, pianos generally use screw-fastened pegs to fix the strings. Specifically, the strings are wound on the pegs, and then the pegs are rigidly tightened to fix the strings. When it is necessary to replace the strings or tune the strings, it is very laborious, especially after the piano has been used for a long time, the pegs are easy to rust, which increases the difficulty of disassembly, and it is easy to damage the tightness of the connection parts, causing the pegs to loosen. use. Contents of the invention [0003] In order to solve the above-mentioned disadvantages existing in fixing the strings by pegs at present, the present invention provides a piano string locking nail which is convenient for string changing and tuning. [0004] To achieve the above ob...
