1. A spinning reel with variable gear ratio transmission, comprising:
a main reel body; a handle rotatably disposed at the main reel body; a rotary shaft extending along an axis and coupled to and driven by the handle to rotate about the axis; a worm unit including a tubular worm shaft that extends along a center line and that is disposed at an angle with respect to the axis, and a worm that is provided on and co-rotatable with the worm shaft; a reciprocating mechanism including a reciprocating shaft extending into the worm shaft, the reciprocating mechanism being coupled to and driven by the rotary shaft to result in back and forth movement of the reciprocating shaft with respect to the center line; a line guiding rotor coupled to and driven by the worm shaft to rotate about the center line; a spool connected to the reciprocating shaft for reciprocating movement with respect to the line guiding rotor; and a variable gear ratio device including an outer worm wheel and an inner worm wheel rotatably sleeved on the rotary shaft, the outer worm wheel having a ring of outer gear teeth meshing with the worm, the inner worm wheel being nested in the outer worm wheel and having a ring of inner gear teeth meshing with the worm, the outer gear teeth surrounding the inner gear teeth, the outer gear teeth and the inner gear teeth being disposed on a common plane, the outer worm wheel having a first gear ratio with the worm, the inner worm wheel having a second gear ratio with the worm, the second gear ratio being smaller than the first gear ratio, the variable gear ratio device further including an adjusting unit for enabling rotation of the rotary shaft to be transmitted to the worm unit via a selected one of the outer worm wheel and the inner worm wheel and for enabling idle rotation of the other one of the outer worm wheel and the inner worm wheel relative to the rotary shaft. |
