Connect fixing axle, the fixing axle is plugged in the centralized positioning part of the housing and raised towards outer face, the rotating shaft it is interior
The inner chamber of the housing is stretched at end, and the inner interval of the rotating shaft is embedded with moveable magnet, the direction motion of the housing
The corresponding part of magnet is provided with fixed magnet, and the moveable magnet is identical with the quantity that the fixed magnet is arranged, the fortune
Gap is left between moving magnet and the fixed magnet.
It is further characterized by:
Preferably, the moveable magnet, arranged for interval on fixed magnet upper and lower end face;
The inner of the rotating shaft is specially the lower plane of annular, if the lower plane is furnished with by center of circle uniform ring of its center
Dry moveable magnet, now the corresponding installation end face of the housing towards the lower plane be provided with horizontal to the correspondence being circular layout
The fixed magnet of quantity;
Every piece of moveable magnet is pre-installed in the corresponding moveable magnet mounting groove of annular mounting structure, the annular installation
It is convex under structure to form overall structure in the lower plane, the annular mounting structure and the lower plane;
The fixed magnet is pre-installed in the corresponding fixed magnet mounting groove of lower annular mounting structure, the lower annular
Mounting structure is convex to form overall structure in the installation end face, the lower annular mounting structure and the installation end face;
Preferably, the moveable magnet, arranged for interval on anchor ring inside and outside fixed magnet;
The inner of the rotating shaft be provided with it is some under convex moveable magnet, every piece of moveable magnet is perpendicular to the rotating shaft
Lower surface arrangement, the outer ring surface that now housing is formed towards the moveable magnet is correspondingly arranged on pair being circular layout
The fixed magnet of quantity is answered, every piece of fixed magnet is vertically arranged;
The upper end of every piece of moveable magnet is installed in the corresponding card holding trough of the inner anchor ring of the rotating shaft respectively, described
Housing is embedded with fixed magnet mounting structure towards the outer ring surface of the lower surface of the rotating shaft, on the fixed magnet mounting structure
Fixed magnet embedding slot is preset with, the fixed magnet is correspondingly arranged in the fixed magnet embedding slot.
After structure using the present invention, rotating shaft connects with housing using only bearing, because power and moment of torsion are mutually inhaled by magnet
Offer is provided, upon rotation of the knob, the attraction between magnet will not produce frictional force, there will not be any noise and produce, this
Outside in operation, only rely on bearing and realize spinfunction, bearing technology is quite ripe at present, and it can be to greatest extent
The generation for preventing catching phenomenon, knob is greatly improved in performance;To sum up, its feel that magnetic force offer knob is provided,
Solve the noise as caused by contact principle, rock, the bad phenomenon such as clamping stagnation, improve the comfort of operating personnel so that knob
Can smooth work.

Embodiment
A kind of magnetic force provides the knob of feel, sees Fig. 1-Fig. 6:It includes the exposed part 1 of turn, housing 2, the exposed part 1 of turn
The outer face of housing 2 is exposed to, the bottom of housing 2 is fixed with base 3, and wiring board 4 is provided with base 3, the exposed part 1 of turn
The inner snaps connection rotating shaft 5, and rotating shaft 5 is loaded on the outer ring surface of bearing 6, and the inner ring surface of bearing 6 snaps connection fixing axle 7, fixing axle 7
It is plugged in the centralized positioning part of housing 2 and stretches into the inner chamber of housing 2 towards outer face projection, the inner of rotating shaft 5, rotating shaft 5
