Rotationally it is positioned above lower casing, the outside provided with jack 94.1 and connecting pole is provided with connecting pole 94, connecting pole in upper casing
It is additionally provided with slot 94.2, the connecting pole and center-wheel arbor, walks third wheel and coordinated by grafting by upper casing and quartz clock type timer
Movement is connected, and in the jack of the central shaft of center-wheel arbor insertion connecting pole and walks the projection insertion connecting pole of third wheel and inserts
(moment of torsion for being applied to upper casing can be transferred to center-wheel arbor) in groove.The outer circumference surface of the upper casing is carved provided with a circle countdown
Degree, 0 position of scale also illustrates that 60 minutes countdown positions.User when rotating upper casing manually can and meanwhile drive away third wheel and in
Heart wheel shaft rotates, and quartz cassette drives upper casing when passing by wheel rotation to be simultaneously rotated.
The relevant parameters such as the width by setting the swing angle of limited block, the width of limited block and shifting block, Ke Yibao
The rotation extreme position that card walks third wheel both direction is completely superposed (rotating range for walking third wheel is just 360 degree) so that set
The utility model can carry out complete timing in 60 minutes.Chip in pcb board can also be adjusted so that walk the rotation of third wheel
A length of 2 hours, 1 minute or other random times during the timing of three-sixth turn.
Mode of operation of the present utility model is：
1st, as shown in figure 5, now for zero position, walk third wheel rotate counterclockwise to extreme position (limited block be located at up time
The extreme position in pin direction), and walk third wheel spring leaf is squeezed on switch column；
2nd, countdown is set：Rotate clockwise away third wheel by the direction of arrow in Fig. 5, now travelling gear and center-wheel arbor it
Between frictional force be not enough to promote quartz cassette output gear, therefore center-wheel arbor occur skid (center-wheel arbor rotate but pass
Moving gear is motionless), simultaneously because after the driving lever for walking third wheel leaves, spring leaf departs from switch column by natural resiliency and recovers outstanding automatically
The chip of dummy status and pcb board sends signal enabling quartz cassette；
If as shown in fig. 6, walking when third wheel is clockwise to extreme position, (limited block is pushed to counterclockwise
Extreme position), the rotational angle for walking third wheel is 360 degree, and the setting time of countdown is 60 minutes；If walking third wheel by up time
Pin turns to optional position (rotational angle is less than 360 degree), and the setting time (being less than 60 minutes) of countdown is with walking turning for third wheel
Dynamic angle is related；
3rd, countdown starts, and quartz cassette exports wheel assembly by center and drives third wheel by the direction of arrow inverse time in Fig. 6
Pin is rotated (travelling gear drives center-wheel arbor to rotate simultaneously by frictional force, and center-wheel arbor drives wheel of passing by rotate again)；
4th, when wheel of passing by turns to position shown in Fig. 5, spring leaf, which is passed by take turns, bends and touches switch column, pcb board
Produce signal enabling sound horn prompting user and simultaneously close quartz cassette, sound duration can pass through the chip in pcb board
Setting.
