When the adjusting gear 24 is rotated manually, the rotation of the adjusting gear 24 drives the outer cylinder 26 to rotate. Elastic blocks 29 are fixedly connected to the base 10 at positions corresponding to the respective adjusting gears 26 one by one, and each elastic block 29 abuts against the teeth of each adjusting gear 26 one by one. Through the cooperation of the adjusting gear 24 and the elastic block 29, a sound will be generated when the adjusting gear 24 is rotated and the rotation feel is better. Windows are respectively formed in the base 10 at positions corresponding to the respective outer cylinders 26 one by one. Digital markings are arranged on the outer peripheral surface of each outer cylinder 26 along its circumferential direction. In this embodiment, there are four outer cylinders 26, and the cooperation of the four outer cylinders 26 and the windows imitates the time display of an electronic clock.

[0052] In the same support assembly, two windows communicate with each other to form a display window 57. Unit identifiers are respectively marked on the base 10 at positions corresponding to each display window 57. The corresponding unit identifiers (hour, minute) are marked on the base 10, so that primary school students can clearly know the unit mark corresponding to each display window.

[0053] When in use, one of the adjustment gears 24 is manually rotated, so that the rotation of the adjustment gear 24 drives the corresponding outer cylinder 26 to rotate, thereby determining the time displayed on the electronic clock, and then adjusting the hour hand 31, minute hand 32 and second hand 33 on the clock dial according to the time of the electronic clock. The second hand 33 can be rotated by hand, and the rotation of the second hand 33 drives the second hand linkage gear 39 to rotate, and the rotation of the second hand linkage gear 39 drives the first large gear 40 to rotate, and the rotation of the first large gear 40 drives the first small gear 41 fixedly connected to the first large gear 40 to rotate, and the rotation of the first small gear 41 drives the second large gear 42 to rotate, and the rotation of the second large gear 42 drives the second small gear 43 fixedly connected to the second large gear to rotate, and the rotation of the second small gear 43 drives the third large gear 44 to rotate, and the rotation of the third large gear 44 drives the first large gear 44 connected to the first large gear 40 to rotate. The third small gear 45 fixedly connected to 44 rotates, and the third large gear 44 rotates and drives the minute hand 32 to rotate at the same time. The third small gear 45 rotates to drive the hour hand linkage gear 34 to rotate, and the hour hand linkage gear 34 rotates to drive the hour hand 31 to rotate. In this way, the hour hand 31, the minute hand 32 and the second hand 33 can be driven to rotate by hand dialing, so that the time displayed on the clock dial is consistent with the time displayed on the electronic clock. Of course, you can also adjust and determine the time displayed on the clock dial first, and then adjust the time displayed on the electronic clock to make it consistent with the time displayed on the clock dial. Through conversion, you can further understand the time and increase the fun. The utility model cooperates with the adjusting gear 24 and the elastic block 29, and a sound will occur when the adjusting gear 24 is dialed, so that primary school students can feel that they are dialing the adjusting gear 24, and the rotation feel is relatively good.
