The rotation of the second shaft axis；Centrifugal-block is around the rotation of the second shaft axis by driving piece that corresponding triggering is driven to drive foreign steamer
Rotation；Triggering driving foreign steamer rotation drives corresponding 5th shaft rotation；The rotation of 5th shaft will pass through corresponding two lists
Corresponding two cams rotation is moved to annulus；Since two cams coordinate with triggering pressing plate respectively；In the initial state two it is convex
The side of protrusion is respectively facing the both sides of triggering pressing plate on wheel；So on the one hand two cam rotations will compress corresponding scrollwork
Spring；On the other hand the rotation of two cams will be made by the corresponding triggering pressing plate of one of cam extrusion triggering pressing plate to
Lower movement；Triggering pressing plate, which moves down, will compress corresponding compressed spring and make compressed spring stress；The compressed spring of stress
It will extrusion friction square plate；So that friction square plate becomes larger with the friction between corresponding first rack；Since centrifugal-block is upper
Driving one end on the outside of lubrication groove symmetrically to have in triggering, there are two arcwall faces；So when compressed spring to trigger pressing plate resistance and
The torsion that the sum of reaction force of two scroll springs pair, two cams is transmitted to centrifugal-block on triggering driving foreign steamer reaches flat
When weighing apparatus state, the driving piece on triggering driving foreign steamer will compress centrifugal-block so that centrifugal-block is moved in corresponding eccentric groove；
I.e. in this state, driving piece will skid with corresponding centrifugal-block；I.e. at this time by drive rack be transmitted to friction it is rectangular
Pressure on plate reaches a stable state；That is friction square plate reaches a stable shape to the frictional force of corresponding first rack
State；On the other hand drive rack, which moves up, simultaneously will drive corresponding first gear to rotate；First gear rotation will band
Dynamic corresponding first rack movement；First rack rubs in moving process with corresponding friction square plate；It is rubbed by this
The movement speed of the first rack can be reduced by wiping power；The speed that drive rack moves down can be reduced by the frictional force.
When drive rack stops mobile, triggering pressing plate returns to original position under the action of compressed spring
On；And two cams also return on original position under the action of corresponding scroll spring and continue to play corresponding triggering pressing plate
To position-limiting action；The effect of unidirectional ring is to prevent cam from being interfered with the 5th shaft in recovery process in the present invention.
Relative to traditional damper technology, the damper that the present invention designs is by rubbing between square plate and the first rack
Friction reduce the movement speed of drive rack；Damping is reached by the friction to rub between square plate and the first rack
Effect.
