Quartz clock type timer movement

A quartz clock-type timer movement, characterized by comprising a shell, wherein a quartz movement body (1), a sound component (9) and a central output wheel assembly driven by the quartz movement body are disposed in the shell, a PCB (2) and a traveling wheel (3) driven by the central output wheel assembly are disposed at a top of the shell, and a battery compartment is disposed at a bottom of the shell;

• wherein the quartz clock-type timer movement is configured such that the traveling wheel (3) can rotate so as to set a timing duration, and in a countdown state, power provided by the quartz movement body can be transmitted onto the traveling wheel (3) through the central output wheel assembly;
• and when the set timing duration is reached, the sound component is started at the moment the traveling wheel (3) triggers an internal switch;
• wherein a leaf spring (21) and a switch pillar (22) are disposed on the PCB, and a toggle rod (31) forcing the leaf spring to bend so as to touch the switch pillar is disposed on the traveling wheel,
• wherein the central output wheel assembly comprises a central wheel axle (4) rotatably positioned on the quartz movement body and connected with the traveling wheel, a transmission gear (5) rotatably positioned on the central wheel axle and engaged with an output gear of the quartz movement body, and a spring pressing sheet (6) used for tightly pressing the transmission gear and the central wheel axle together to generate a driving frictional force between the transmission gear and the central wheel axle;
• wherein the transmission gear is provided with a central hole (51) matched with a central shaft, and a concave hole (52) matched with a pressing disc (42) of the wheel axle is formed in a bottom surface of the transmission gear.
