2nd, number of assembling steps：

（One）, mobile lock-bit component 90 assembles：

A, the logical block through hole 19 on through hole square 95 is inserted in into connecting shaft to lead in block 16, the shoulder block shrinkage pool 69 on through hole square 95 It is enclosed on connecting shaft shoulder block 15, logical block nut 17 and the cooperation of the logical screw thread of block stud 18 are limited in shoulder block shrinkage pool 69 is rotatable On connecting shaft shoulder block 15；

B, first the draw ring rotating shaft 96 for adjusting one end on draw ring 99 is inserted among the through hole of a handle hole seat 97, then by elasticity Regulation draw ring 99 is further bent made of material, and the draw ring rotating shaft 96 of the other end on regulation draw ring 99 is also inserted into another Among the through hole for hole seat 97 of shaking hands；

C, front and rear slider throughbores 26 are passed through into the blind termination of block 46 of connecting shaft on mobile link axle 91, in advance by self-locking spring 92 One end prop up on the baseplane of spring shrinkage pool 39, blind piece of through hole 49 on blind hole square 93 is inserted in the blind block 46 of connecting shaft, It is to be slidably matched between the surrounding outer rim of blind hole square 93 and the square hole periphery of square half-blind hole 29 4；

Blind piece of nut 47 and the blind screw thread of block stud 48 coordinate by the baseplane of spring shrinkage pool 39 tightly against mobile link axle 91 with Step surface between the blind block 46 of connecting shaft；The other end of self-locking spring 92 is propped up on the described baseplane of square half-blind hole 29.

（Two）, seat turns slide plate 80 and assembled with chair framework 70：

A, two sliding block screws 89 are taken to pass through to fix after the through hole of two ear 98 movable sliding block 94 is fixed on into seat lower plane 86 On；

B, the V-type protruding rail 77 of the rear end of chair framework 70 is engaged with the V-type groove 88 of the front end of seat lower plane 86；

C, hold regulation draw ring 99 with a finger and slightly rotate, blind hole square 93 is held and is retracted into the square bottom of half-blind hole 29 In plane, such as the state of accompanying drawing 12, further it is slidably matched between V-type protruding rail 77 and V-type groove 88, moves forward and backward 94 liang of sliding block Side is interspersed between through hole depth tooth 64 and blind hole depth tooth 67；

D, finger unclamps regulation draw ring 99, and such as the state of accompanying drawing 13, connecting shaft shoulder block 15 is limited in because shoulder block shrinkage pool 69 is rotatable On, maximum probability situation is：Through hole square 95 is blocked on the lateral surface of through hole depth tooth 64 and the shallow tooth 66 of through hole, in self-locking spring 92 Under the effect of reset itself power, certain frictional resistance is produced；Blind hole square 93 is still retracted within square half-blind hole 29, and V-type is convex It can continue to relatively move between rail 77 and V-type groove 88；Mobile link axle 91 now can be shallow from through hole symmetrical above and below It is without hindrance between tooth 66 to slide；

E, after the front and back position relation that seat turns between slide plate 80 and chair framework 70 is adjusted in place, V-type is relatively moved slightly Position and by adjusting the reversing reset rotating through hole square 95 of draw ring 99 between protruding rail 77 and V-type groove 88 so that through hole square Complete alignment orientation between 95 and through hole depth tooth 64, under the reset itself power of self-locking spring 92 further effect, blind hole square 93 Eject square half-blind hole 29 and more than half position is entered among blind hole depth tooth 67, such as the state of accompanying drawing 11, at the same time, through hole square 95 also completely among through hole depth tooth 64；Complete seat and turn the fast velocity modulation of front and back position between slide plate 80 and chair framework 70 It is whole, and through hole square 95 and blind hole square 93 combine lock-bit, and it is firm to consolidate.

（Three）, chair framework 70 assembles with crank throw lifting column 20

A, hinge pivot pin 30 passes through corner support hole 73 and holder through-hole 27 successively, and pivot pin nut 33 is matched somebody with somebody with the screw thread of pivot pin stud 31 Close, pivot pin block 32 is kept off on the alien invasion of corner support seat 74 of side, pivot pin nut 33 keeps off the corner support in opposite side On 74 alien invasions of seat；

B, corner regulation slash 50 is connected with crank throw lifting column 20, and low level supported hole 54 and one of corner lockhole 25 is right Standard, low pin stud 42 pass through low level supported hole 54 and corner lockhole 25 successively, and a hand pinches manual block 41, another hand Manual nut 43 is pinched, by manual nut 43 and the immovable fitting of low pin stud 42 so that manual block 41 is close to side On the alien invasion of low level support base 53, manual nut 43 is close on the alien invasion of low level support base 53 of opposite side；

C, corner regulation slash 50 is connected with chair framework 70, and high pin stud 62 is passed through into high-order supported hole 56 and skeleton successively Bore 65, by high-order pin nut 63 and the immovable fitting of high pin stud 62 so that high pin block 61 is close to a high position for side On the alien invasion of support base 57, high-order pin nut 63 is close on the alien invasion of high-order support base 57 of opposite side.

3rd, using process：In Fig. 1-5：

（One）, when adjusting seat and turning 80 height of slide plate, crank throw batter post 21 is inserted into the car on the bicycle rack 10 being engaged In seat mounting hole 11, vehicle frame seat trip bolt 12 is tightened, it is ensured that crank throw batter post 21 is located in vehicle frame seat mounting hole 11 Proper height；

（Two）, when adjusting seat and turning 80 front and back position of slide plate, hold regulation draw ring 99 with a finger and slightly rotate, hand push Seat turn slide plate 80 towards wanted adjustment direction relative to chair framework 70 move after；Finger unclamps regulation draw ring 99, and passes through tune Save the reversing reset rotating through hole square 95 of draw ring 99 so that complete alignment orientation between through hole square 95 and through hole depth tooth 64, The reset itself power of self-locking spring 92 is further under effect, blind hole square 93 ejects square half-blind hole 29 and more than half position enter it is blind Among hole depth tooth 67, through hole square 95 is also completely among through hole depth tooth 64；Complete seat and turn slide plate 80 and chair framework Front and back position quickly adjusts between 70.

（Three）, when adjusting seat and turning 80 angle of inclination of slide plate, a hand pinches manual block 41, and another hand, which is pinched, sets about Dynamic nut 43, manual nut 43 and low pin stud 42 are unclamped, and corner low level lock pin 40 are extracted, by selecting corner lock up and down Hole 25 is aligned again with low level supported hole 54, and corner low level lock pin 40 is passed through into low level supported hole 54 and corner lockhole successively again 25, manual nut 43 and low pin stud 42 are tightened again, finished.

4th, the essential characteristics of the above-mentioned protrusion of the present invention directly bring following significant progressive effect：

1st, seat turns that cooperation can be moved forward and backward with V-type groove 88 using V-type protruding rail 77 between slide plate 80 and chair framework 70, with reference to Mobile lock-bit component 90 realizes that convenient adjustment seat turns moving forward and backward between slide plate 80 and chair framework 70.The specific structure is not But meet public demand, and can allow trick special group out of proportion, easily adjust bicycle seat front and back position, really Guarantor rides more comfortable.

2nd, using the effect of the reset itself of self-locking spring 92 in mobile lock-bit component 90, with reference to blind hole square 93 and through hole square 95 coordinate with blind hole depth tooth 67 and the lock-bit of through hole depth tooth 64 simultaneously, and front and back position adjustment is quick, and firm firm.
