sequence of mechanical actions of the whole device:

when the centrifugal wheel works, the shock absorption column 17 is pressed to move downwards, so that the shock absorption column push plate 15 is driven to move downwards, the primary shock absorption spring 13 is compressed, meanwhile, the push plate pull rope 18 is pulled, the wire wheel 31 is rotated, the wire wheel shaft 33 is driven to rotate, the reset torsion spring 45 is twisted, the driving friction wheel 34 is driven to rotate, the driven friction wheel 44 is driven to rotate, the driven friction wheel shaft 38 is driven to rotate, the spline sleeve 51 is driven to rotate, the centrifugal wheel shaft 70 is driven to rotate through the transmission belt 54, and the centrifugal wheel 55 is driven to rotate;

if the pressure on the shock absorption column 17 is small and the pressing speed is slow, the downward movement speed of the shock absorption column push plate 15 is small, so that the rotation speed of the wire wheel 31 is slow by pulling the push plate pull rope 18, the rotation speed of the centrifugal wheel 55 is small, the centrifugal force on the centrifugal block 47 is smaller than the pulling force of the centrifugal block spring 48, the centrifugal block 47 is still kept in the centrifugal block sliding cavity 49, the magnetic sliding plate 30 still keeps the initial position, and the downward movement of the shock absorption column push plate 15 only overcomes the elastic force of the primary shock absorption spring 13, namely the effect of buffering the pressure on the shock absorption column 17 can be achieved only by the elastic force of the primary shock absorption spring 13;

when the punching pressure on the shock absorbing column 17 is larger, the pressing speed is higher, the downward moving speed of the shock absorbing column push plate 15 is higher, so that the rotating speed of the centrifugal wheel 55 is increased, the centrifugal force on the centrifugal block 47 is increased to be larger than the pulling force of the centrifugal block spring 48, the centrifugal block 47 overcomes the pulling force of the centrifugal block spring 48 and moves outwards to touch the upper baffle 56 and the baffle 52, the upper baffle 56 and the baffle 52 are pushed, the baffle 52 moves downwards, the left slide plate pull rope 29 and the right slide plate pull rope 19 are loosened, the magnetic slide plate 30 moves towards the side close to the secondary shock absorbing cavity 21 under the elastic force of the magnetic slide plate spring 28 until the bayonet 24 is close to the secondary shock absorbing cavity 21 side, meanwhile, the upper baffle 56 moves upwards, the left bayonet pull rope 46 and the right bayonet pull rope 23 are loosened, and the bayonet 24 moves upwards to the magnetic slide plate cavity 27 under the elastic force of the bayonet spring 25, the bayonet 24 clamps the magnetic sliding plate 30 to prevent the magnetic sliding plate from moving in the direction far away from the secondary damping cavity 21, at this time, the repulsive force of the magnetic sliding plate 30 to the toothed magnet 63 enables the toothed magnet 63 to overcome the pulling force of the magnet sliding cavity 61 and move in the direction close to the push rod through cavity 65 to be meshed with the rack 12, so that the rack 12 moves downwards to drive the toothed magnet 63 to move downwards, the pressing block 60 is driven to move downwards, the secondary damping spring 20 is compressed, and the damping column pushing plate 15 moves downwards to overcome the elastic forces of the primary damping spring 13 and the secondary damping spring 20, so that the distance of the damping column 17 moving downwards is reduced;

when the damper column push plate 15 moves downwards to stop, the push plate pull rope 18 is stopped to be pulled, the wire wheel 31 stops rotating, the centrifugal wheel 55 stops rotating, the centrifugal block 47 loses centrifugal force, the centrifugal block 47 moves towards the side close to the centrifugal wheel shaft 70 to the centrifugal block sliding cavity 49 under the action of the pulling force of the centrifugal block spring 48, the upper baffle plate 56 and the baffle plate 52 move towards the side close to the centrifugal wheel 55 under the action of the elastic force of the upper baffle plate spring 57 and the baffle plate spring 50 respectively, the bayonet pin 24 moves downwards slowly due to the action of the friction force of the one-way friction block 26, the magnetic sliding plate 30 is still clamped by the bayonet pin 24, the toothed magnet 63 is meshed with the rack 12, and when the damper column push plate 15 moves upwards under the action of the elastic force of the primary damper spring 13 and the secondary damper spring 20, the push plate pull rope 18 is loosened, thereby causing the reel shaft 33 to rotate reversely under the torsion of the reset torsion spring 45, and driving the centrifugal wheel 55 to rotate reversely, thereby causing the centrifugal block 47 to move outward again under the centrifugal force until touching the upper baffle 56 and the baffle 52, when the damper post push plate 15 moves upward to the initial position, the release of the torsion of the reset torsion spring 45 is completed, the reel 31 stops rotating, thereby causing the centrifugal wheel 55 to stop rotating, at this time, the magnetic slide plate 30 is still clamped by the bayonet 24, the toothed magnet 63 still keeps engaged with the rack 12, until the pressure on the damper post 17 is reduced, the downward movement speed of the damper post 17 is reduced, thereby causing the rotation speed of the centrifugal wheel 55 to be reduced, thereby causing the centrifugal block 47 to keep in the centrifugal block sliding cavity 49, thereby causing the bayonet 24 to move downward to the initial position, and the right bayonet 23 and the left bayonet rope 46 are loosened, thereby causing the upper baffle 56 to move downward to the initial position under the elastic force of the upper baffle spring 57, at this time, the magnetic sliding plate 30 moves to the initial position in the direction far away from the secondary damping cavity 21 under the elastic force of the magnetic sliding plate spring 28, so that the toothed magnet 63 loses the repulsive force, the toothed magnet 63 moves to the push rod through cavity 65 in the direction far away from the push rod through cavity 65 under the tensile force of the magnet sliding cavity 61, the toothed magnet 63 is disengaged from the rack 12, so that the rack 12 does not drive the pressing block 60 to move downwards due to the downward movement, and at this time, the damping column pushing plate 15 only needs to overcome the elastic force of the primary damping spring 13 due to the downward movement, so that the damping effect is ensured;

if the sensitivity of the adjustment of the damping stroke needs to be improved, that is, when the damping column 17 is subjected to a smaller pressure and the downward movement speed thereof is slower, the upward elastic force applied to the damping column pushing plate 15 is increased, the screw rod 41 is rotated to move the slider 37 leftward to drive the slide rod 69 leftward to move the friction wheel shaft seat 36 leftward to drive the driven friction wheel shaft 38 leftward to move the driven friction wheel shaft 38 leftward to abut against the large diameter portion of the driving friction wheel 34, at this time, the driven friction wheel 44 moves the driven friction wheel 44 downward due to the tapered side surface of the driving friction wheel 34 to drive the driven friction wheel shaft 38 downward to drive the friction wheel shaft seat 36 downward to compress the shaft seat spring 39, at this time, the transmission ratio between the driving friction wheel 34 and the driven friction wheel 44 is increased, that is, when the rotation speed of the driving friction wheel 34 is lower, the rotation speed of the driven friction wheel 44 can be increased from the rotation speed of the driving friction wheel 44 to the previous large pressure applied to the The rotation speeds are consistent, so that when the shock absorbing column 17 is subjected to small pressure, the downward movement of the shock absorbing column push plate 15 can be buffered by the elastic force of the primary shock absorbing spring 13 and the secondary shock absorbing spring 20.

The invention has the beneficial effects that: can be according to the shock attenuation post received pressure and its speed that moves down, the elasticity that the automatic adjustment shock attenuation post push pedal received, thereby make the shock attenuation post receive pressure when less, can guarantee its enough long buffer stroke, thereby ensure that the shock attenuation post can obtain sufficient buffering, and the shock attenuation post receives pressure when great, also can guarantee that the shock attenuation post moves down the distance and can not be too big, thereby avoid elementary damping spring to warp too big and damage, can change the sensitivity of shock attenuation stroke adjustment simultaneously, make the device can be applicable to the shock attenuation requirement under the different operation environment.
