Problems solved by technology

The second-hand strings are at the other end away from the string head. Due to the long-term winding on the outer diameter end of the knob, a spiral string tail is formed, which is difficult to store after disassembly
If the existing plastic bag is used for storage, it is easy to aggravate the distortion of the second-hand strings

Abstract

The invention discloses a device facilitating storage of second-hand strings. The device comprises a cylinder and a sleeve. The right end of the cylinder is provided with an oblique circular concave hole. The outer diameter end of the right portion of the cylinder is provided with a circular check ring. The outer diameter end of the circular check ring is provided with anti-slip grains. The left end of the cylinder is provided with a circular concave hole in the axial direction. The left part of the cylinder is provided with an external thread. The wall thickness part, on the right side of the external thread, of the left portion of the circular concave hole is provided with a plurality of first circular through holes evenly distributed in the radial direction. A threaded hole is formed in the sleeve in the axial direction. An internal thread of the threaded hole is connected with the external thread of the cylinder in a matched mode. A second circular through hole is formed in the part, between the outer diameter end of the cylinder and the inner diameter of the sleeve, of the circular check ring. The device facilitates storage of the second-hand strings and cannot exacerbate distortion of the second-hand strings.

Description

technical field [0001] The invention relates to the technical field of musical instrument parts, in particular to a device for storing second-hand strings. Background technique [0002] The strings include a string head and a string body, and the string body is threaded on the string head through a string buckle. The second-hand strings are at the other end away from the string heads. Due to the long-term winding on the outer diameter end of the knob, a helical string tail is formed, which is difficult to store after being disassembled. If the existing plastic bags are used for storage, it is easy to aggravate the twisting and deformation of the second-hand strings. Contents of the invention [0003] The object of the present invention is to provide a device that facilitates the storage of second-hand strings without aggravating the distortion of the second-hand strings. [0004] The technical solution of the present invention is to design and manufacture a device for st...
