Background technology

The fish device that slips is a kind of fishing accessory, slips stretch cord one end of fish device to be connected to fishing rod afterbody, and the fish device that slips is fixed on the position of the convenient fishing of fisherman.When occurring large fish in fish process in lifting, fishing rod and fishing line will reach capacity degree time, for preventing folding pole, breaking makes large fish run away, fishing people generally unclamps fishing rod, at this moment stretch cord pulls out from slipping fish device, start to slip fish, when the unable resistance of fish, elastic thread is recovered to and slips in fish device thus fishing rod and fish retracted.

Through retrieval, find two sections and the akin Chinese patent open source literature of present patent application:

1, a kind of hand lever rope of accidentally dropping, publication number is: CN201557472U, comprises rubber band line, is characterised in that and also comprises housing and line wheel, housing arranges fixed axis, offers line outlet; Line wheel is inserted on the fixed axis in housing, and rubber band line one ends wound is taken turns online, and the other end is drawn from line outlet; Connected by torsion spring between housing and line wheel; Housing is arranged anti-down card, online wheel arranges sour jujube groove, and anti-down card inserts in sour jujube groove, line can be stoped to take turns reversing take-up, but do not hinder line to take turns unidirectional rotating forward outlet.

2, box type losing grip can be fixed, publication number: CN203968995U, comprise: shell (1), the center of described shell is connected central fixed shaft (4) by nut (9) with buckle (8), described shell shape is disc and there is arc groove at edge, described buckle is connected to outer side by central fixed shaft, described central fixed shaft connects wind spring (3), the outer end of described wind spring connects drum (2), there is seal gasket (10) at described drum and central fixed shaft two ends, described drum connects losing grip (6), the line outlet place of described shell connects active card (5), described shell is fastening by screw (7).

Through reading over above-mentioned two sections of documents, Problems existing is as follows:

1, in documents 1, fixed axis and housing are solidly installed, and during unwrapping wire, wind spring is entangled on newel, and during take-up, wind spring opens, and can only move anti-down card by fishing people, are difficult to the opportunity grasping reverse take-up.

2, in documents 2, central fixed shaft is same with shell to be solidly installed, and because accidentally dropping, rope mostly is elastica, and stretching after-contraction length is subject to the factor impacts such as Rabi oscillatory, time, temperature, pulling force.In the process of take-up, if do not regained completely when wind spring opens elastic thread completely, when drum is because of inertia continuation rotation, drum drives wind spring reverse-winding in central fixed shaft, at this moment wind spring will fracture or occur irregular winding, and now damaged can not unwrapping wire or take-up for wind spring.

Another problem that this documents exists is, the rope of fish device of slipping mostly is stretch cord, and the length that stretching after-contraction is wound around affects by the factor such as Rabi oscillatory, pulling force, and length be can not determine, therefore there is the halfway problem of take-up.In order to solve the halfway problem of take-up, generally in assembling process, certain pretightning force is applied in advance to wind spring, but this pretightning force is only according to the experiential operating of operator, not unified standard, not only reduce installation effectiveness like this, do not solve the halfway problem of take-up completely simultaneously.

The central shaft of above-mentioned two sections of documents is all solidly installed with shell, there is relatively big difference with present patent application in technical scheme.
