A musical toy currently on the market, as shown in
FIG. 1
, comprises a spiral spring
12
linked to a spindle
11
, whereas by pulling a pulling ring

12
, when releasing the pull ring
10
, the restoring force of the spiral spring
12
rotates the spindle
11
to link a gear box
13
to activate a sound device
14
to broadcast sounds, thus attracts a user's attention. A later device is to install lighting devices, which requires a battery
16
and a switch
17
to operate its function, which device has increased cost and makes the structure complicated.
In view of this and many other shortcomings, the inventor has derived the present invention.
SUMMARY OF THE INVENTION
It is the primary object of the present invention to provide a self-electric power generator to activate the lighting devices of the toy.
It is another object of the present invention to provide a self-electric power generator, which uses mechanic movement to generate electric power, thus saves energy.
It is a further object of the present invention to provide a self-electric power generator, which is easy to install and safe in use.
