In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design one kind can improve the clock and watch hairspring of the precision of walking, including clock and watch hairspring body, clock and watch hairspring body includes the spring leaf, clock and watch hairspring body is the vortex structure that the spring leaf convolutes into the circle, the outer lane of spring leaf is the outer lane spring leaf, the inner circle of spring leaf is the inner circle spring leaf, the inboard fixed mounting of inner circle spring leaf has the collet, the epiboly is installed in the outside of outer lane spring leaf, the top of epiboly is seted up with outer lane spring leaf assorted recess, the outer lane spring leaf is located the recess, the recess intussuseption is filled with the photocuring adhesive, the outer lane spring leaf is fixed in the recess through the photocuring adhesive.

Preferably, the bottom of clock and watch hairspring body installs two discs, the central point of two discs puts to rotate and installs the balance staff, the balance staff runs through the collet, and rotates with the collet and be connected.

Preferably, the top of pendulum shaft rotates installs the disc, the epitaxy fixed mounting of disc has a plurality of linking arms, the linking arm is around disc evenly distributed.

Preferably, the outer end of the connecting arm is fixedly provided with a rim, and the rim and the disc form a concentric ring structure.

Preferably, a bridge plate is fixedly installed on the outer side of the bottom end of the double-disc.

Preferably, a rough surface layer is fixedly mounted on the inner side of the spring piece, and the rough surface layer is of a one-way sawtooth structure.

The utility model provides a pair of can improve clock and watch hairspring of precision of walking, beneficial effect lies in: the outer-ring spring leaf is fixed by means of a light-cured adhesive, the free end of which is slightly deformed by the weight of the light-cured adhesive, which causes undesirable mechanical stresses in the balance spring before hardening, the light-cured adhesive all having sufficient fluidity to enable the free end of the outer-ring spring leaf to spontaneously return to its rest position, the stresses induced in the balance spring thus self-eliminating when depositing drops of light-cured adhesive, reducing the inertia force of the balance wheel and the errors of the timepiece.
