See Fig. 2, between handle bar 9 and sleeve pipe 91, be provided with elastic adjusting mechanism 8.Elastic adjusting mechanism 8 includes base tube 81, holding sheet 82 and pretightning force adjustment structure 83.Base tube 81 is set in outside handle bar 9.Base tube 81 is located in sleeve pipe 91.Holding sheet 82 is made up of some pieces of fricting strips 821.Fricting strip 821 is circumferentially distributed along base tube 81.Fricting strip 821 is provided with some slide bars 822 radially extending axial distribution along base tube.Slide bar 822 slides and is arranged in base tube 81.The inner of slide bar 822 is provided with the 3rd spring 823.3rd spring 823 drives fricting strip to be connected to together with sleeve pipe 91 by slide bar.The pretightning force adjustment structure 83 of outer shifting includes two conical heads 831 and some push rods 832.Conical head 831 is tubular structure.Base tube 81 is linked together in being set on handle bar 9 and be located in base tube 81 by conical head 831 with handle bar 9.Conical head 831 is only slidably connected in base tube 81.Circumferentially distributed axially extending along base tube 81 of push rod 832.The all of slide bar 822 of same fricting strip 821 is supported on same push rod 832 by the 3rd spring 823, and the slide bar of each piece of fricting strip is respectively supported by a push rod.

Seeing Fig. 3, two conical heads 831 are slidably connected in the two ends of base tube 81 in the way of miner diameter end is arranged oppositely.The two ends of push rod 832 are shelved on the conical surface of two conical heads 831.Pretightning force adjustment structure 83 also includes driving structure 833.Jacking block 8331 in driving structure 833 to include two two ends being threaded in base tube 81.Jacking block 8331 is set on handle bar 9.Two conical heads 831 are between two jacking blocks 8331.

See Fig. 1, during use, amortisseur designs threaded rod, links together with this utility model in threaded rod is threaded in screwed hole 4.It is connected in the connecting pin of vehicle frame realize amortisseur is fixed on vehicle frame by connecting ring 1.It is held on sleeve pipe 91 by hands and moves.

See Fig. 2 and Fig. 3, the process of the elastic effect adjusting sleeve pipe is: drive conical head 831 axially moving along base tube 81 by rotating jacking block 8331, conical head 831 drives push rod 832 moving radially along base tube 81, and push rod 832 extrudes the 3rd spring 823 and changes pretightning force.

Embodiment two, with the difference of embodiment one be:

See Fig. 4, in connecting ring 1, be equipped with internal ring 5.Internal ring 5 is iron structure.Internal ring 5 is linked together with connecting ring 1 by rubber ring 7.

The inner peripheral surface of rubber ring 7 is provided with several circumferentially distributed blind holes 71 (outer peripheral face that blind hole is arranged on rubber ring is also possible) along rubber ring.Division board 72 it is provided with in blind hole 71.Blind hole 71 is divided into two cavitys i.e. inner chamber body 711 and outer chamber 712 by division board 72.The flexible lid of open end cap 73 of blind hole 71.Elastomeric cap 73 is towards the internal bowl-type arched upward of blind hole 71.

Seeing Fig. 5, division board 72 is provided with some main friction passage 75.Main friction passage 75 communication with cavity body 711 and outer chamber 712.It is provided with friction plate 76 in main friction passage 75.

See Fig. 6, friction plate 76 is equipped with some can along the distribution arrangement of inner chamber body and outer chamber i.e. figure above-below direction slide friction lever 77.Friction lever 77 is cylindrical.Friction lever 77 is provided with a friction passage 78.Prop up friction passage 78 and connect the space (i.e. outer chamber in connection) of friction plate 76 upper and lower.Two axial ends 771 of friction lever 77 are all sphere.

See Fig. 7, two axial ends 771 of friction lever 77 are designed with some grooves 772.Groove 772 is circumferentially distributed along friction lever 77.

The absorbing process of rubber ring is, see Fig. 4 to Fig. 7, all fill in inner chamber body 711 and outer chamber 712 liquid (can certainly make this utility model time filling liquid), when panel and horizontal fixed plate produce vibration and are expressed to rubber ring 7 and cause blind hole 71 to deform, flowing, friction plate 76 and friction lever 77(see Fig. 5 back and forth between inner chamber body 711 and outer chamber 712 to make liquid) produce and rock, vibrational energy is changed into heat energy during rocking and consumes by liquid flowing and friction plate and friction lever.If vibrate less and when being not enough to promote blind hole to deform, the most only the rocking of liquid, during liquid sloshing, friction lever produces and rocks and energy-absorbing

Embodiment three, with the difference of embodiment two be；

See Fig. 8, also include drive mechanism 6.Internal ring 5 is rotatably connected in rubber ring 7, and rubber ring 7 is fixed together with connecting ring 1.

Drive mechanism 6 includes ratchet 61, the ratchet 62 of driving pawl and drive rod 63.Ratchet 61 is coaxially connected together with internal ring 5.Ratchet 61 is structure as a whole with internal ring 5.Ratchet 62 is fixed in one end of drive rod 63.Connect seat 3 and be provided with slide opening 31.The other end of drive rod 63 can be located in slide opening 31 in two dimension slip.Drive rod 63 is provided with deposits hole 64.Deposit hole 64 and have two.Deposit and hole 64 is equipped with engagement spring 65.Engagement spring 65 is extension spring.One end of engagement spring 65 links together with drive rod 63, and the other end links together with connecting seat 3.When engagement spring 65 is in free state, under the effect of engagement spring 65 spring, ratchet 62 can be engaged in ratchet 61.

During use, connect seat 1 and be connected to one end of amortisseur, drive rod 63 along the radial direction slidably clasp joint other end (two ends of amortisseur are can relatively to draw close i.e. to stretch with separating) in amortisseur connecting ring.When amortisseur receives vibration and produces contractile motion, drive rod 63 translates (i.e. top in Fig. 6 is moved), now ratchet 62 towards connection ring 1 and can rotate clockwise by driving pawl 61, ratchet 61 drives inner ring 5 to rotate clockwise, when amortisseur extends, drive rod 63 moves down, now ratchet 62 can not driving pawl 61 rotate and when ratchet 62 touches the tooth on ratchet 61, drive rod 63 makes drive rod 63 to reset away from ratchet 1, when ratchet 62 does not touch the tooth on ratchet 61, under the effect of engagement spring 65, ratchet 62 moves to right and resets.So that during each vibration period, the impact site suffered by internal ring 5 is different, and internal ring 5 is shifted one's position continuously in a circumferential and is withstood shocks thus be not easy to be deformed and become oval.
