Be fixed with the upper end of the outer tube arm of force 39 at the right part of turning cylinder 45, one end of the lower end of the outer tube arm of force 39 and pipe link 38 flexibly connects, one end of the other end of pipe link 38 and the special-shaped ratchet arm of force 37 flexibly connects, and the other end of the special-shaped ratchet arm of force 37 is fixed on the following middle part of special-shaped ratchet 36.

Special-shaped ratchet 36 is fan-shaped, have three flank of tooth teeth, ratchet radius between second of its back and the 3rd tooth is maximum, the 3rd is contrary tooth 48, be provided with to stretch out on the first tooth right side of special-shaped ratchet 36 and be " L " type touching lever 35, special-shaped ratchet 36 fits on the vertical shaft 34 on the vertical shaft frame 42 by special-shaped ratchet hole 50, and fork 26 fits on the vertical shaft 34 by the fork axis hole 49 under it, and fit over the right side of special-shaped ratchet 36, and fit on the vertical shaft 34 fork 26 is moving with nut 43.

Vertical shaft frame 42 rectangular shapes, its vertical surface bottom is fixed with vertical shaft 34, and horizontal surface is fixed on the frame, and the contrary tooth papillae pawl slide bar 30 fixing at vertical shaft frame 42 end faces be crooked arcuation, and the arcuation of bending is towards opposite above the connector of its arcuation and fork 26; Be provided with two apertures above the contrary hock 25 in location, the aperture of its rear end is movably connected on the Connection Block of vertical shaft frame 42 tops, an end of being furnished with spring 6 in the aperture of its front end, on the fixing vertical shaft frame 42 thereunder of the other end of spring 6, the pawl point of the contrary hock 25 in location matches with the flank of tooth of special-shaped ratchet 36.

On fork 26 connectors, be provided with two holes up and down, the right side of fork 26 connectors is flexibly connecting the middle part of push rod 24 in its hole that has, the right-hand member of push rod 24 is fixed on fork 26 connectors of its top with spring 6, force the other end of push rod 24 to be pressed on the ratchet nose bar 33 fixing on special-shaped ratchet pawl 32 hook tips, it has seam 58 at the left end of push rod 24; The set hole, middle part of special-shaped ratchet pawl 32 is movably connected on the another hole of the fork 26 connector left sides on it, be fixed with an end of spring 6 at special-shaped ratchet pawl 32 other ends, on the other end side's fixed thereon of spring 6 fork 26 bodies, under the effect of elastic force, force the pawl point of ratchet pawl 32 to be crushed on all the time above the left side of push rod 24; When driving riding boogie board 27, push rod 24 underside of forward faces clash into the set touching lever 35 in the special-shaped ratchet 36 first tooth right sides, rotate counterclockwise thereby drive special-shaped ratchet 36; It above the connector of fork 26 aduncate arcuation riding boogie board power bar 28, be fixed with riding boogie board 27 at its top, the left side above the connector of fork 26 is fixed with and presses down nose bar 29, pressing down nose bar 29 is and colludes shape, collude on the contrary tooth papillae pawl slide bar 30 of vertical shaft frame 42 upper fixed, an end of being furnished with spring 6 at riding boogie board power bar 28 middle parts of fork 26, the other end of spring 6 are admittedly on thereunder the frame.

When motor bike is parked on the ground, left and right outer tube 41 is in plumbness, landing wheel 1 by two lands and is supporting, this moment, contrary tooth papillae pawl 25 was assigned in location (as shown in Figure 7) on the contrary tooth 48, when needs travel, only need pin riding boogie board 27 twice, 28 drivings of riding boogie board power bar press down the contrary tooth slide bar 30 of nose bar 29 compressings and press down, force contrary tooth papillae pawl 25 to break away from contrary tooth 48, and special-shaped ratchet pawl 32 just in time fall into first tooth (as shown in Figure 6) of special-shaped ratchet 36.Push rod 24 in the driving process on the fork 26 just is provided with to stretch out with the first tooth right side at special-shaped ratchet 36 and is " L " type touching lever 35 and collides, make special-shaped ratchet 36 gaps turn over bidentate to turn over≤90 °, along with 6 effects of the big extension spring spring on the fork 26, with fork 26 together with special-shaped ratchet pawl 32 arrive second with the 3rd against the ratchet radius maximum between the tooth 48, make when special-shaped ratchet pawl 32 is elevated and to be locked (as shown in Figure 5) by 58 jack-up of the seam on the push rod 24, meanwhile because the special-shaped ratchet arm of force 37 of special-shaped ratchet 36 rotating drive, pipe link 38, the outer tube arm of force 39 makes a left side, right outer tube is turned back to parastate and is locked from plumbness.If navigating mate is stepped on second and third pin driving by mistake,, and, special-shaped ratchet pawl 32 lays the foundation owing to being elevated to special-shaped ratchet 36 cws turn round because special-shaped ratchet pawl 32, can not promote special-shaped ratchet 36 runnings by the locking of 58 jack-up of the seam on the push rod 24.The simultaneously blocked expansion link 2 that also has left and right outer tube 41 has been promoted by last lower connecting rod and has been colluded arm 16 and collude and do.

When need stop in the arrival destination of travelling, sole 40 is stepped on the right side that the navigating mate only using foot is stepped on earlier on the tee T riding boogie board 10, the right side step on sole 40 depress in string thimble 31 near ending jack panel 43, string core bar 56 pulling detents 12 break away from stop gear 17 in forcing, on go here and there core bar 52 and slide.This moment, outer tube 41 changed plumbness into from parastate, 1 did not land but land wheel, because outer tube 41 is from vertically to parallel process, the expansion link 2 of outer tube 41 has been promoted by last lower connecting rod and colluded arm 16 and collude and do.Meanwhile in its process, special-shaped ratchet 36 is clockwise rotated by pipe link 38, at this moment special-shaped ratchet pawl 32 maintains static with fork 26, because special-shaped ratchet pawl 32 is elevated, so special-shaped ratchet 36 rotates smoothly, forward position near first tooth, just in time contrary tooth papillae pawl 25 falls into contrary tooth 48 location, and as shown in Figure 7, the support 21 that the stop bar 57 on the while turning cylinder 45 is fixed on the crossbeam 18 blocks the location.Navigating mate is formerly stepped on the right side on the tee T riding boogie board 10 and is stepped on and step on a left side again behind the sole 40 and step on sole 11, a left side is stepped on sole 11 and is depressed string thimble 53, last string thimble 53 is near ending jack panel 43, forcing the pulling of string core bar 52 to collude lower end that arm deciliter control stalk 54 colludes arm 16 by its connecting rod mechanism pulling makes and colludes preceding nose bar 15 other ends (as shown in figure 12) that arm 16 tops break away from " fourth " word shape, under the effect of outer tube 41 upper springs 6 elastic force, expansion link 2 and on land the wheel 1 rapid bullet earthward.The meanwhile moving shrinkproof ratchet 5 that fits on the nose bar 44 of back, because shrinkproof ratchet 5 rear ends are fixed on down on the string core bar 3, in the process of 2 times bullets of expansion link, connecting rod mechanism is in shrinkproof ratchet 5 when parallel breaking away under ratchet sheet 8 states with outer tube 41, and shrinkproof ratchet 5 is close to rapidly on the ratchet sheet 8.Because shrinkproof ratchet 5 is close on the ratchet sheet 8, make that the wheel 1 that lands on the expansion link 2 can only stretch into downwards, can not can adapt to the different requirement of ground height to top offset.

As shown in Figure 2, the utility model is when being used for not being with pedal motorcycle, remove the special-shaped ratchet arm of force 37, pipe link 38, the outer tube arm of force 39 under the special-shaped ratchet 36, with special-shaped ratchet 36 and on match mechanism, directly be fixed on the right-hand member of turning cylinder 45 by special-shaped ratchet 36.
