please refer to Fig. 1, Fig. 2, Fig. 3 in conjunction with Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, sketch principle of work of the present invention: suppose that mounting hole on connecting panel 2 22 and the seat basin side plate 30 use bolts on seat fix, spanner 10 is connected with the spanner hole 63 of spanner case, so, under normal circumstances, 1) in the time will making the height of seat cushion suitably heighten, the end of spanner 10 is applied to a upward force, spanner 10 is done clockwise direction rotation by connecting screw together with spanner case 6, positioning boss 64 on spanner case 6 is made clickwise thereupon, drive ratchet 48 by positioning boss 64, drive successively pawl disk 47, fixed mount 46 rotates, ratchet 48 and ratchet 49 are in lockup state, now, because being equipped with separating sheet 461 between teeth groove 483 and gear ring 493, ensure that ratchet 48 and ratchet 49 only have locking on one side, thereby the ratchet 49 that rotarily drives of ratchet 48 rotates, ratchet 49 is coordinated and then is driven shifting block 44 to rotate by boss hole 492 and ratchet boss 442, shifting block 44 is by gear protruding 1, keep off protruding 2 444, keeping off protruding 3 445 promotion rollers 43 moves, roller 43 contacts and produces relative motion with the outer circumference surface of drive block 42 simultaneously, thereby drive drive block 42 to rotate, the splined hole 421 arranging in the middle of drive block 42 and spline 12 flush fits of center shaft 1, thereby drive center shaft 1 to rotate, output gear 11 on center shaft 1 is meshed with the tooth plate 20 on seat, thereby band moving tooth plate 20 opposite spins, seat is raise.When the upward force shedding on spanner 10, by the screen resilience of retracing spring 3, a pair of return spring on retracing spring 3 hooks the 31 return spring faces 472 that act on pawl disk 47, and then drive pawl disk 47 resiliences, thereby drive ratchet 48 returns, teeth 482 depart from gear ring 493, now, because having separating sheet 461 between teeth groove 483 and gear ring 493, ensure that teeth 482 do not contact with gear ring 493, simultaneously, a pair of return spring on retracing spring 3 hooks the 31 return spring grooves 65 that act on spanner case 6, thereby be with wrench 10 resiliences by spanner case 6, now, because roller 43 is when the interior rolling of raceway 422 of drive block 42, because lockstitching a border 423 for inclined-plane, can ensure to apply application force on center shaft 1 time, can not drive center shaft 1 to rotate, thereby ensure arrangement for adjusting height reliable lock.In the time that spanner case 6 goes to maximum position, the positive stop lug boss 61 arranging on spanner case 6 contacts with the position-limited edge 24 arranging on connecting panel 2, has ensured the upwards scope of rotational angle of spanner case 6.2) in the time will making the height of seat cushion suitably turn down, the end of spanner 10 is applied to a downward force, spanner 10 is done anticlockwise direction rotation by connecting screw together with spanner case 6, the corresponding left-hand revolution of doing of positioning boss 64 on spanner case 6, drive successively ratchet 48 by positioning boss 64, pawl disk 47, fixed mount 46 rotates, ratchet 48 and ratchet 49 are in lockup state, now, because being equipped with separating sheet 461 between teeth groove 483 and gear ring 493, ensure that ratchet 48 and ratchet 49 only have another side locking, thereby the ratchet 49 that rotarily drives of ratchet 48 rotates, ratchet 49 coordinates by boss hole 492 and ratchet boss 442, and then drive shifting block 44 to rotate, shifting block 44 is by gear protruding 1, keep off protruding 2 444, keeping off protruding 3 445 promotion rollers 43 moves, roller 43 contacts and produces relative motion with the outer circumference surface of drive block 42 simultaneously, thereby drive drive block 42 to rotate, the splined hole 421 arranging in the middle of drive block 42 and spline 12 flush fits of center shaft 1, thereby drive center shaft 1 to rotate, output gear 11 on center shaft 1 is meshed with tooth plate 20, thereby band moving tooth plate 20 opposite spins, seat is reduced.When the downward force shedding on spanner 10, by the screen resilience of retracing spring 3, a pair of return spring on retracing spring 3 hooks the 31 return spring faces 472 that act on pawl disk 47, and then drive pawl disk 47 resiliences, make ratchet 48 returns, teeth 482 depart from gear ring 493, now, because having separating sheet 461 between teeth groove 483 and gear ring 493, ensure that teeth 482 do not contact with gear ring 493, simultaneously, a pair of return spring on retracing spring 3 hooks the 31 return spring grooves 65 that act on spanner case 6, thereby be with wrench 10 resiliences by spanner case 6, now, because roller 43 is when the interior rolling of raceway 422 of drive block 42, because lockstitching a border 423 for inclined-plane, can ensure to apply application force on center shaft 1 time, can not drive center shaft 1 to rotate, thereby ensure arrangement for adjusting height reliable lock.In the time that spanner case 6 goes to maximum position, the positive stop lug boss 61 arranging on spanner case 6 contacts with the position-limited edge 24 arranging on connecting panel 2, has ensured that spanner case 6 rotates the scope of angle.
