The invention discloses a method for designing a playing mechanism of a mechanical music time-telling clock movement with a hammer (spring) supplying motive power, and relates to the technical field of timing instruments. According to the technical scheme, spring or hammer type mechanical energy serves as power of the mechanical clock movement, the movement formed by a power transmission mechanism, a traveling transmission mechanism, a traveling control mechanism and the playing mechanism is integrally designed, and various parts of the movement are independently designed. The method is characterized by sequentially including the steps of selection and orchestration of classical songs and design optimization of playing styles and the playing mechanism. Compared with the prior art, the method has the outstanding substantive features and remarkable progressiveness that Chinese national classical songs can be played in four periods through the mechanical music time-telling clock movement with the hammer (spring) supplying the motive power.
