The working process of the invention is as follows: as shown in fig. 9 and 10, in the initial state, four corners of the operating pedal 7 are supported by the swing plates 27 in the corresponding actuator unit 18, the swing plates 27 are in the horizontal state and supported by the support blocks 30, and the C-plate spring 24 is stretched. In a state where the actuator unit 18 of the operating pedal 7 is not supported, the piston 44 a abuts against the inner wall of the front end of the case 21, the B spring 46 is uncompressed, the C rack 22 and the C gear 34 are not engaged, the B gear 42 is located outside the actuator groove 17, the C leaf spring 24 is not extended, the swing plate 27 forms an acute angle of between 20 ° and 25 ° with the horizontal plane, and the upper end of the swing plate 27 does not protrude out of the actuator groove 17. The B guide block 14 is located at the front end of the B guide groove 15, and the B plate spring 13 is in a compressed state.

When the working pedal 7 needs to be lowered, the position enabling the swinging plate 27 to reset and swing into the execution groove 17 by the C plate spring 24 is manually lifted upwards, and then the working pedal 7 is manually and quickly pressed down; during which a plurality of execution units 18 are passed over, the actions in the passed execution units 18 are: the B rack 12 moves down rapidly along with the working pedal 7, and the B rack 12 is in strong impact engagement with the B gear 42; due to the pre-compression of the B plate spring 13, the good meshing of the B rack 12 and the B gear 42 is ensured; at the moment, the one-way clutch 41 plays a one-way driving role, the strong impact of the rack B12 is transmitted to the piston A44 through the gear B42, the one-way clutch 41, the shaft A40, the gear A43 and the rack A20, the piston A44 is subjected to strong pressure instantly, then according to the characteristics of the non-Newtonian fluid, the non-Newtonian fluid in the box shell 21 is basically in a solid state, the piston B45 basically cannot extrude the spring B46, and the gear B42 basically cannot rotate; because the gear B12 presses the gear B42 downwards, the box shell 21 and the mechanism arranged on the box shell 21 synchronously move downwards quickly, and the S spring 28 is compressed; when the box shell 21 moves downwards for a certain distance under the early strong impact of the rack B12, the impact of the rack B12 is gradually weakened, the pressure of the piston A44 on the non-Newtonian fluid is gradually weakened, and the non-Newtonian fluid is gradually liquefied from a solid state, so that the piston A44 can slowly push a part of the non-Newtonian fluid to pass through the round hole of the partition plate 37 to apply pressure to the piston B45, the spring B46 is compressed, and the piston B45 drives the rack C22 to slowly move towards the direction of the gear C34 through the slide strip 38; when the housing 21 moves downwards to the limit and the S spring 28 is compressed to the limit, the inclined surface of the B rack 12 is just contacted with the column 32, the C rack 22 pushed to move towards the C gear 34 does not reach the limit, and then the C rack 22 is not meshed with the C gear 34 and the C rack 22 passes over the C gear 34; with the continuous downward movement of the B rack 12, under the action of the cylinder 32 pressing the inclined plane of the B rack 12, the B rack 12 overcomes the pre-pressure of the B plate spring 13 through the B slider 10, the B rack 12 moves towards the B plate spring 13, and further the B rack 12 is disengaged from the B gear 42, so that under the reset action of the S spring 28, the mechanism arranged on the box shell 21 and the mechanism arranged on the box shell 21 synchronously move upwards to reset, under the reset action of the B spring 46, the B piston 45, the sliding strip 38 and the C rack 22 move to reset, and the B piston 45 pushes the non-Newtonian fluid to enable the A piston 44 to drive the A rack 20 to move to reset. After the B rack 12 completely passes through the column 32, the B rack 12 is moved and reset by the reset action of the B leaf spring 13.

When the working pedal 7 is quickly pressed down to the position with the required height, the working pedal 7 is placed on the upper side of the execution groove 17 with the required height, the external force on the working pedal 7 is removed, the working pedal 7 falls under the self gravity of the working pedal 7, the B rack 12 falls to the execution groove 17 with the required height along with the working pedal 7, and the execution unit 18 acts: the B rack 12 is in weak impact meshing with the B gear 42, at the moment, the one-way clutch 41 plays a one-way driving role, weak impact of the B rack 12 is transmitted to the A piston 44 through the B gear 42, the one-way clutch 41, the A shaft 40, the A gear 43 and the A rack 20, the A piston 44 is subjected to weak pressure, then according to the characteristics of non-Newtonian fluid, the non-Newtonian fluid in the box shell 21 is still in a liquid state, the A piston 44 can slowly push the non-Newtonian fluid, the B gear 42 can slowly rotate, finally, the B rack 12 pushes the A piston 44 through the B gear 42, the one-way clutch 41, the A shaft 40, the A gear 43 and the A rack 20, the A piston 44 can slowly push a part of the non-Newtonian fluid to pass through a round hole of the partition 37 to pressurize the B piston 45, the B spring 46 is compressed, and the B piston 45 drives the C rack 22 to; because the gear B42 rotates slowly and the gear B rack 12 presses the gear B42 downwards, the box shell 21 and the mechanism arranged on the box shell 21 synchronously move downwards slowly, the downwards moving speed is slower and slower, and the S spring 28 is compressed; when the box shell 21 moves downwards for a short distance due to early weak impact of the rack B12, the impact of the rack B12 is gradually weakened, the pressure of the piston A44 on the non-Newtonian fluid is gradually weakened, the flow speed of the non-Newtonian fluid is accelerated, further, the displacement of the piston A44 pushing the non-Newtonian fluid reaches the limit in a short time, the compression amount of the spring B46 reaches the maximum, the piston B45 drives the rack C22 to move to the limit in the direction of the gear C34 through the sliding strip 38, at the moment, the rack C22 and the gear C34 are in a tangent state, and the gear B42 and the gear A43 can not be driven to rotate any more; during the period that the C rack 22 moves to the limit towards the C gear 34, the downward displacement of the casing 21 does not make the C rack 22 pass over the C gear 34, and the C rack 22 is meshed with the C gear 34, and the height of the working pedal 7 is higher than that of the swinging plate 27. When the working pedal 7 continuously falls down by self weight, the gear B42 is not driven to rotate any more, the gear B12 only enables the box shell 21 and the mechanism arranged on the box shell 21 to synchronously move downwards continuously, then the gear C22 drives the swinging plate 27 to swing downwards through the gear C34, the gear D33, the gear D35 and the shaft D36, and the plate spring C24 is stretched; the downward swing of the swing plate 27 causes the upper end of the swing plate 27 to swing out of the execution slot 17, and the working pedal 7 is still positioned at the upper end of the swing plate 27 in the process; with the synchronous downward continuous movement of the case shell 21 and the mechanism arranged on the case shell 21, the C rack 22 is disengaged from the C gear 34, the swinging plate 27 swings upward and resets under the reset action of the C plate spring 24, but the downward movement of the working pedal 7 limits the swinging and resetting of the upper end of the swinging plate 27, and the upper end of the swinging plate 27 contacts with the lower surface of the working pedal 7; when the working pedal 7 continuously falls down by self weight, the above-described C rack 22 and the column 32 are repeatedly pressed to move and reset the casing 21 and the mechanism mounted on the casing 21, the working pedal 7 presses the swinging plate 27 to continuously move downwards until the swinging plate 27 swings to the horizontal position and is supported by the supporting block 30, so that the swinging plate 27 can limit the downward movement of the working pedal 7 and can well support the swinging plate 27. The action of adjusting the height of the operating pedal 7 downward is finished.

When the working pedal 7 needs to be adjusted upwards, the position enabling the swinging plate 27 to reset and swing into the execution groove 17 by the C plate spring 24 is manually lifted upwards, and then the working pedal 7 is manually lifted upwards; during which a plurality of execution units 18 are passed over, the actions in the passed execution units 18 are: the B rack 12 passes through the cylinder 32 by means of the extrusion of the upper end inclined plane and the cylinder 32, the B rack 12 is meshed with the B gear 42, but under the overrunning action of the one-way clutch 41, the B gear 42 rotates and cannot drive the A shaft 40 to rotate through the one-way clutch 41; the B rack 12 will pass over the B gear 42; the wobble plate 27 is not actuated during the entire period.

When the working pedal 7 is quickly adjusted to the position with the required height, the working pedal 7 is manually and quickly placed on the upper side of the execution groove 17 with the required height, the external force on the working pedal 7 is removed, and the process that the working pedal 7 falls down by the gravity of the working pedal 7 so that the swinging plate 27 of the execution unit 18 in the execution groove 17 supports the working pedal 7 is repeated. The action of adjusting the height of the operating pedal 7 upward is finished.
