Manipulation, and the setting of location hole and locating slot are greatly improved the accuracy of pressing, less mistake by the case where occur.
3, the utility model limits transfer part by setting, and the rotation of cam can be made to be limited in certain range, compression bar
It lifts and declines and be always to maintain same position, operated convenient for player.
4, the utility model can make the movement between cam and mandril become rolling by the way that runner is arranged in mandrel ends
Friction ensures the flexibility of cam rotation, meanwhile, it also can avoid sliding friction and issuable noise.In addition, runner is straight
Diameter is set greater than the internal diameter of body, and the limit of mandril is realized using the outer profile of runner, ensures that mandril will not skid off, together
When, the slewing area that also can avoid cam is excessive.
5, the body of the utility model can be directly embedded into qin body, be may also set up connection screw thread and connect with qin body, pass through company
The mode for connecing screw thread connects, and can avoid leading to the problem of loosening between body and qin body.
6, spring card is arranged in ram surface in the utility model, can be arranged between spring card and qin body and reset bullet
Spring consequently facilitating the return of mandril, ensures that the post to which the strings of a musical instrument are attached that cuts on mandril is detached with string, and then ensures that cutting the post to which the strings of a musical instrument are attached does not interfere with string
Pronunciation.
7, double chord an ancient plucked stringed instrument is routinely played, and the head of people is to can't see right side sound-changing device in the left side of qin, can only left side
It is conveniently operated, the corresponding string in right side, which can be simultaneously reached, when operating sound-changing device cuts a string and change voice effect.It can ensure to play not in melody
The performance of required variation sound in music is completed in the case of intermittent.If someone's custom is played, head is on the right side of qin
It plays, that is reversed in installation sound-changing device.
