The central axle comprises a bottom pressure plate 42 and a central shaft 41 fixed on the pressure plate, and the upper part of the central shaft is provided with an assembly notch 46. The central wheel shaft is rotatably positioned on a support column 11 of the quartz movement (the bottom surface of the pressure plate is provided with a shaft hole matched with the support column), and the central shaft upwards extends out of the core shell through a through hole of the upper cover.

The transmission gear is respectively provided with a central hole 51 for the central shaft to pass through, a concave hole 52 positioned on the bottom surface and a transmission gear 53 positioned on the outer circumferential surface. The transmission gear is rotationally positioned on the central wheel shaft, the concave hole of the transmission gear covers the pressure plate of the central wheel shaft (the inner diameter of the concave hole is larger than the outer diameter of the pressure plate), and the transmission gear of the transmission gear is meshed with the output gear 12 of the quartz movement. The transmission gear and the spring pressing piece are sequentially sleeved on the central shaft, the edge shape of a pressing piece central hole 61 on the spring pressing piece is suitable for the position of a central shaft plane 43 (the spring pressing piece and the central shaft cannot rotate relatively), and the spring pressing piece is firmly fixed on the central shaft by the deformation generated after the riveting point 45 on the central shaft is riveted, and suitable axial pressure is applied to the transmission gear. The central wheel shaft and the transmission gear are pressed tightly by the axial pressure, so that the power of the quartz movement can be transmitted to the central wheel shaft through the transmission gear (a friction material can be arranged between the top surface of the pressure plate and the bottom surface of the concave hole to ensure enough friction force). The quartz movement, the PCB and the central output wheel assembly can also be obtained by outsourcing.

The utility model discloses an operation mode is:

1. as shown in fig. 5, in this case, the return-to-zero position is obtained, the over wheel rotates counterclockwise to the limit position (the limit block is located at the limit position in the clockwise direction), and the over wheel presses the spring piece on the switch post;

2. setting a countdown: rotating the knob 24 clockwise according to the arrow in fig. 5 to rotate the over wheel, at this time, the friction between the transmission gear and the central wheel shaft is not enough to push the output gear of the quartz movement, so that the central wheel shaft slips (the central wheel shaft rotates but the transmission gear does not move), and meanwhile, after the deflector rod of the over wheel rotates away, the spring piece is separated from the switch column by the elasticity of the spring piece to automatically recover the suspension state and the chip of the PCB board sends a signal to start the quartz movement;

as shown in fig. 6, if the passing wheel is rotated clockwise to the limit position (the limit block is pushed to the limit position in the counterclockwise direction), the rotation angle of the passing wheel is 360 degrees, and the set time for countdown is 60 minutes; if the passing wheel is clockwise rotated to any position (the rotating angle is less than 360 degrees), the set time (less than 60 minutes) of countdown is related to the rotating angle of the passing wheel;

3. when the countdown starts, the quartz movement drives the passing wheel to rotate anticlockwise according to the arrow direction in the figure 6 through the central output wheel component (the transmission gear drives the central wheel shaft to rotate simultaneously through friction force, and the central wheel shaft drives the passing wheel to rotate again); meanwhile, the display module also displays the running time by using numbers according to the signals provided by the PCB;

4. when the walking wheel rotates to the position shown in fig. 5 (the timing time is up), the spring piece is bent by the walking wheel and touches the switch column, the time displayed by the display module is the set time, and the number of the pointer opposite to the display panel is 0; the PCB generates a signal to start the loudspeaker to sound to prompt a user, and simultaneously the quartz movement is closed, and the sound production time can be set through a chip in the PCB.
