As the lock body 155 moves upward and downward by the link 184, the cambridge 152 provided in the lock body 155 also moves up and down and is formed at the front end of the cambridge 152 ( 159 is in the form of pressing the upper and lower portions of the concave portion 158 of the cam 157 inserted into the Cambridge 152 finely.

Therefore, since the cam 157 inserted into the cambridge 152 is retracted to the rear of the cam groove 156, the present fixed gear 164 can be engaged with the lock gear 151 to be engaged.

In the engaged state as described above, the present fixed gear 164 can move the string 105 in the tensioned state and relaxed state by moving in the same direction as the lock body 155 moving together with the base 181.

When the arm 195 is up and down as described above, the lock gear 151 and the present fixed gear 164 are engaged with each other in a spaced apart state at the time of full-tone operation. Since the string guide roller 187 fixed to the tip of the saddle 188 is moved to the front or rear of the string 105 in a state in which it is connected to the string 105, it does not cause a disturbance in the front sound.

When the arm 183 is returned to its original position after the up and down is completed, the base 181 and the lock body 155 are returned to their initial state by the self restoring force, and the fixed gear 164 is also the lock gear 151. Spaced back to the original state.

When the string fixed gear 165 is returned to its original state after the electric sound effect is generated, the tuned string 105 is held by the spring 167 connected between the string fixed gear 165 and the spring fixture 170. Because it is in the state, it is in the same state as the initial tuning.

This is because the tension of the spring 167 connecting the string fixing gear 164 and the spring fixture 170 in the state in which the string 105 is tuned is provided for each string 105, the string fixing gear This is because, even if 164 is rotated forward and backward, it is engaged in the tuned state by the lock gear 151, and each of the present fixed gears 164 does not move, but is rotated integrally and then returns to its original state.

In particular, if any of the strings are broken after the playing process or performance, only the broken string 105 needs to be replaced without the inconvenience of replacing the entire string as in the prior art, and the end of the string 105 is replaced when the string 105 is replaced. Discomfort such as having to cut the fixing portion provided in the can be eliminated.

Then, the height, height of the saddle 188 can be easily obtained by using one of the up and down adjustment bolt 186.

The present invention as described above has a spring with a different modulus of elasticity for each string so that the strings do not need to be stringed even after playing. If you want to get the sound effect by operating the arm, the lock gear and the string fixed gear are connected to each other so that the sine state is not changed, which can contribute to the user's convenience and the performance and quality of the string instrument.
