Please refer to the first to third figures, the creation of the "electromagnetic fishing teaching aid device", which comprises a fishing rod (10), and a power generating unit (20) and a metal fishing line (shown on the fishing rod (10)). 30), where:

The fishing rod (10) is a generally telescopic or fixed length rod having a grip (11) for the user to hold at one end and a positioning portion (12) at the other end for the metal fishing line ( 30) Support the fixed position in the middle section.

The power generating unit (20) is disposed at a suitable position of the grip portion (11), and is provided with a generator (22), a gear set (23) and a bulb (24) on the inner edge of the outer casing (21); the generator ( 22) A drive shaft (221) is protruded from one end, and the drive shaft (221) can be directly or indirectly combined with the rocker (25) provided on the outer side, and a positive guide piece (222) and a negative electrode guide are protruded from the other end. Tablet (223).

Next, the gear set (23) is disposed between the generator (22) and the crank handle (25), and is configured to include a first large gear (231) driven by the crank handle (25), and the first gear (231) a first pinion (232) driven by a large gear (231), a second large gear (233) rotating coaxially with the first pinion (232), and a set of transmissions disposed on the generator (22) The shaft (221) is engageable with the second large gear (233) by the second large gear (233), and the gear set (23) is arranged to enable the user to accelerate the rotation when the crank (25) is rotated. The generator (22) rotates to generate electricity.

Furthermore, the bulb (24) is disposed on the side of the outer casing (21) corresponding to one of the positive and negative guide plates (222, 223), one end of which is outwardly convex, and the other end is electrically connected to a circuit. The board (241), the circuit board (241) is electrically connected to the positive and negative guide sheets (222, 223).

The metal fishing line (30) is composed of a positive wire (31) and a negative wire (32), and can be an enameled wire generally having a conductive property, and one end of the positive wire (31) is electrically connected to the positive electrode guide (222). And the negative electrode lead (32) is electrically connected to the negative electrode guide (223), and the other ends of the positive and negative conductive wires (31, 32) are guided through the positioning portion (12) and then vertically extended. And a metal fishing lure (33) is fixed at the end.

Thereby, by the arrangement of the power generating unit (20) and the metal fishing line (30), when the power generating unit (20) generates a current due to the rotation of the crank (25), the metal fishing lure (31) can be made electromagnetic. Suction, the user can carry out the use of magnetic fishing metal fishing fish, showing different fishing play, and can be used as a teaching tool of electromagnetic principle to achieve educational and musical purposes. In summary, this creation has its excellent progress and practicality in similar products. At the same time, it has not been found in the technical materials of such structures at home and abroad, and the same structure exists in the literature. The creation already has new patent requirements, and the application is filed according to law. The above embodiments are intended to exemplify the present invention, and various modifications, modifications, and applications to those skilled in the art are intended to be included in the scope of the present invention.
