Point cylinder arrange in two grades of cylinder step bathtub constructions, the cylindrical base of spring base is opened at two breach and is had centrosymmetric
Outside two pawl；Inside two claw on the cover plate covers outside two pawl on spring base；Outside two pawl and rotor pit
Interior two projection offsets, and by spring base drive plane scroll spring inner ring hook rotate counterclockwise together snap in cover plate to
In interior two claw；The inner ring hook of the plane scroll spring catches on the varus hook on the cylinder of spring base, plane scroll bullet
The outer ring hook of spring catches on the cylindrical positioning pins of insertion stator pin-and-hole.
After above-mentioned technical proposal, the present invention has following positive effect：
（1）Present invention saves spring retainer ring（Or cylindrical positioning pins）, spring base limit two parts of shield, simplify cam
The structure of phaser and part, reduce cost, simplify assembly process.
（2）Present configuration is simple, reasonable in design, and fixed pan scroll spring is more reliable, and more simple when assembling
It is single, moreover it is possible to ensure that plane scroll spring does not operationally axially jump circle, plane scroll spring force value stabilization can be effectively ensured, improve
Phaser governing speed, control stability and realize knock-off cam axle return.
（3）The present invention increases by a pair of raised steps on rotor, and pawl in increase by a pair on cover plate, by fixed pan scrollwork bullet
The device of spring is fixed and is limited on rotor, and axially and radially all fixes spacing to which so as to fixed reliable；Plane scroll spring
Axial space is limited in certain space by fixing device, and plane scroll spring will not jump circle or doubling-up, and spring force value is steady
It is fixed.

Specific embodiment
（Embodiment 1）
See Fig. 1 to Fig. 8, the present invention has the cover plate 3 and stator 5 fixed by 4 force fit of cylindrical positioning pins；Above cover plate 3
It is provided with spring base 1；Rotor 6 is placed with inside stator 5；It is characterized in that：Between spring base 1 and cover plate 3, winding is provided with plane whirlpool
Coil spring 2, spring base 1 are arranged in two grades of cylinder step bathtub constructions by plane 1-1 of upper part and the cylinder 1-2 of lower part,
Open at two breach 1-3 and there is centrosymmetric outside two pawl 7 in the cylinder 1-2 bottoms of spring base 1；Inside two card on cover plate 3
Pawl 8 covers outside two pawl 7 on spring base 1；Outside two pawl 7 is offseted with two projections 11 in 6 pit of rotor, and passes through spring base 1
