[0034] Working principle: When turning pages of the perpetual calendar, the spur gear 3 is first manually rotated. The rotation of the spur gear 3 drives the roller 4 to rotate synchronously. The rotation of the roller 4 further drives the connecting block 5 and the connecting block 6 to rotate. The page turning operation of the perpetual calendar is realized through the linkage of the connecting block 5 and the connecting block 6, thus achieving a stable page turning effect. This solves the problems of unstable gear meshing, asynchronous page turning, and jamming, which helps to improve the transmission reliability and service life of the perpetual calendar. When inserting fixing block 1, fixing block 2, connecting block 5, and connecting block 6 into the inner walls of embedding slots 11, 10, 12, and 13 respectively, first manually insert fixing block 1, fixing block 2, connecting block 5, and connecting block 6 into the inner walls of the corresponding embedding slots 11, 10, 12, and 13. By limiting and constraining them through embedding slots 11, 10, 12, and 13, a stable installation of fixing block 1, fixing block 2, connecting block 5, and connecting block 6 is achieved, thus achieving a stable nesting effect, which helps to ensure the reliability and durability of the device. In actual use, this perpetual calendar with gear transmission not only achieves stable page turning, but also provides a secure nesting effect.
