This utility model is further arranged to: described elastic salient point is set to two and centrosymmetry is arranged.

By using technique scheme, elastic salient point centrosymmetry is arranged, and the conflict to password circle is steady, so that Password circle by the power of disalignment, thus will not reduce abrasion when password circle rotates on female row, improves password circle Service life.

This utility model is further arranged to: is provided with boss inside described feel wheel, described female row is provided with and supplies The bar groove that boss slides.

By using technique scheme, boss is conflicted at bar groove, so that feel wheel will not rotate relative to female row, During regulation password circle, providing the feel rotated for password circle, help password delineation position, the processing of bar groove structure is simple.

This utility model is further arranged to: described feel wheel also includes the elastic arm connecting elastic salient point, described elastic arm edge The lateral wall of feel wheel extends, and described elastic salient point is arranged at the free end of elastic arm.

By using technique scheme, utilize elastic arm band dynamic elasticity salient point discrepancy bayonet socket, simple in construction, subtracted by elastic arm Friction at few elastic salient point, improves the service life of feel wheel.

This utility model is further arranged to: described feel wheel is plastic material.

By using technique scheme, the feel wheel of plastic material has only to make mold injection molding, adds Work is convenient, and low cost, it is simple to produce in enormous quantities.

This utility model is further arranged to: be provided with slide block outside described password circle.

By using technique scheme, password circle is conveniently adjusted by arranging of slide block, thus the most more Add conveniently, and password circle can be in order to recognize digit position, even if light is poor can also carry out unlocking operation.

This utility model is further arranged to: the end of described female row connects " M " the shape card preventing password circle from deviating from Circle.

By using technique scheme, the end of female row is provided with buckling groove, is snapped in by M shape collar, utilizes collar to support Touching password circle, be fixed on female row by password circle, low cost, easy to assembly, M shape collar is many with the contact point of password circle, fixing Effective.

This utility model is further arranged to: also include the union joint being arranged on two ends, described union joint include connector, Blind hole and through hole, described through hole and blind hole lay respectively at connector both sides, and pin arrives blind hole through through hole and fixes, and forms Guan Bi Structure is with connecting.

By using technique scheme, connector provides position for connecting other structures such as chain, and pin is through logical Hole is positioned blind hole, easy for installation, and pin passes in the hole of the chain link in chain, it is achieved the installation of chain, convenient accurate.

This utility model is further arranged to: be provided with the instruction salient point of instruction password on described female row.

By using technique scheme, arranging of salient point of instruction can preferably differentiate password, facilitates user of service to reconcile Password circle, it is thus possible to quickly open coded lock.

In sum, this utility model has the advantages that

1, the feel wheel utilizing plastic material replaces the rotation of feel pad regulation password circle, weares and teares little, uses comfortable；

2, reasonable in design, convenient installation.
