Summary of the invention

The utility model is at the prior art situation, steering gap was little when technical problem to be solved provided a kind of check, the double bird type back-stop mechanism that can bear big check moment of torsion is first purpose, provides a kind of simultaneously and need not to increase quiet mechanism and just can eliminate the double bird type back-stop mechanism that the tap-tap that sends under the non-return state is second purpose.

Technical problem of the present utility model is achieved through the following technical solutions:

Fishing lines reel double bird type back-stop mechanism, it includes main body, being located at the line shell of main body side and ratch is in transmission connection and is sleeved on the main shaft, can be around the main shaft rotating, be located at the back-stop mechanism in the line shell, the bottom internal circular surfaces of its line shell is a ratchet, the ratchet of disjunctor and bird sheet are movably connected on the main body by screw, effect has torsion spring on the bird sheet, guarantee the engagement of ratchet and ratchet, the shifting shaft of handling the rotation of bird sheet is installed on the main body to be stirred by coupled check button, the bird sheet and the ratchet that it is characterized in that described disjunctor are provided with two, form the double bird type structure, the C shape circular arc camber by the shifting shaft top promotes, and two ratchets that make that two bird sheets rotate and ratchet be engagement formation non-return state or out of mesh non-stop state alternately.

Described ratchet end is arranged with fixing silencing cover respectively.

The utility model is owing to adopted the back-stop mechanism of double bird type, under the certain condition of the ratchet number of teeth, two bird sheet ratchets replace and ratchet engaged, rotate a tooth engagement originally once, just mesh once and rotate half tooth now, therefore steering gap reduces half during check, and the check moment of torsion that can bear increases and is twice, conversely under the constant situation of check moment of torsion, hook tooth just can reduce one times, thereby improve the intensity of hook tooth, be not subjected to high low temperature effect, do not lose efficacy; Need not to increase quiet mechanism and make simple in structurely, realize quietly by silencing cover, can not send big sound.
