Dual-directionally operated dynamo set

A dual-directionally operated dynamo set, comprising a housing, an actuating mechanism slidably mounted in the housing in a reciprocal manner, a dual-motion structure mounted in the housing and driven by the actuating mechanism, and a dynamo device mounted in the housing and driven by the dual-motion structure, wherein:

• the dual-motion structure includes a positioning plate mounted in the housing, the positioning plate is formed with formed with an oblique first slide slot and an oblique second slide slot;
• the dual-motion structure further includes a drive gear rotatably mounted between the positioning plate and a bottom of the housing and driven by the actuating mechanism;
• the dual-motion structure further includes a first driving gear and a second drive gear each rotatably mounted between the positioning plate and the bottom of the housing and each meshing with the drive gear, the first driving gear may slide in the first slide slot of the positioning plate and may be rotated and moved by the drive gear to operate the dynamo device, the second drive gear may slide in the second slide slot of the positioning plate;
• the dual-motion structure further includes a torsion spring mounted on the drive gear and having a first end urged on the first driving gear and a second end urged on the second drive gear;
• and
• the dual-motion structure further includes an idler rotatably mounted between the positioning plate and the bottom of the housing, so that the second drive gear may be rotated and moved by the drive gear to mesh with the idler to operate the dynamo device.
