Fishing reel with a unidirectional control device

A fishing reel comprising:

• a spool base adapted to be detachably secured on the fishing rod and having multiple limit holes defined in the spool base;
• a rotating plate rotatably engaged with the spool base and having a plurality of concavities defined around a peripheral edge of the rotating plate;
• a spool sandwiching the rotating plate with the spool base and having a handle firmly connected to one side of the spool;
• a limiting wheel rotatably engaged with the rotating plate and having:
• a driving roller recess defined in the limiting wheel at a first side facing the spool;
• a plurality of first guide trenches defined in the limiting wheel to communicate with the driving roller recess and inclinedly extending from the driving roller recess in a first direction;
• a plurality of second guide trenches defined in the limiting wheel to communicate with the driving roller recess and inclinedly extending from the driving roller recess in a second direction opposite to the first direction of the first guide trenches;
• a biasing member deformably received in each respective first guide trench;
• a brake block movably received in each respective first guide trench to be selectively engaged with a corresponding one of the biasing members;
• and
• a plurality of springs secured on a second side of the limiting wheel to contact with the rotating plate, wherein the springs provide a resistance for actuating of the unidirectional rotation of the fishing reel;
• a driving roller received inside the roller recess and synchronously rotatable with the spool to engage with the brake blocks;
• a locking device mounted on the spool base to selectively limit the rotating of the limiting wheel;
• and
• an assembling means for keeping the spool base, the rotating plate, the spool, the driving roller, and the limiting wheel assembled together,
• wherein each guide trench is particularly defined to allow the brake block to freely rotate and move close to the biasing member when the driving roller rotates in one direction, but to limit the brake block from rotation and leave the biasing member to perform unidirectional rotating status of the spool;
• and
• the second guide trenches are kept empty.
