As a further improvement, the material piece of should moving away to avoid possible earthquakes mechanism for having the shockproof, this material piece upper end is fixed in this well bottom pipe end through holding the ring tightly, and this material piece lower extreme supports in this back tripod stationary plane.

As the utility model discloses a further improvement, be equipped with the stop gear who prescribes a limit to well pipe range of beating between this holding ring and this back tripod stationary plane, this stop gear is equipped with a spacing groove including this holding ring, still includes that one end is fixed in this back tripod stationary plane and the other end card goes into the spacing of this spacing inslot all the time to this spacing one end becomes the T structure, is convenient for prescribe a limit to this back tripod stationary plane through this holding ring with this well pipe.

As a further improvement, one end of the limiting strip is fixed on the fixing surface through a screw and a group of washers, so that the height of the limiting mechanism can be adjusted conveniently.

The utility model has the beneficial technical effects that: front tripod is by well pipe in the bicycle frame with mechanism of moving away to avoid possible earthquakes, headstock pipe and both ends are constituteed with the connecting pipe that this headstock pipe and well union coupling are fixed respectively, this back tripod rotates through this axis subassembly and this connecting pipe middle part to be connected, this well bottom of pipe supports in this back tripod stationary plane through the mechanism of moving away to avoid possible earthquakes, this mechanism of moving away to avoid possible earthquakes is for having the material spare of moving away to avoid possible earthquakes, this material spare upper end is fixed in this well bottom of pipe through holding the tighting ring, and this material spare lower extreme supports in this back tripod stationary plane, design simple structure like.

Furthermore, a limiting mechanism for limiting the jumping amplitude of the middle pipe is arranged between the tightening ring and the fixing surface of the rear tripod, the limiting mechanism comprises a limiting groove, one end of the limiting mechanism is fixed on the fixing surface of the rear tripod, the other end of the limiting mechanism is clamped into a limiting strip in the limiting groove all the time, one end of the limiting strip is of a T-shaped structure, the middle pipe is limited on the fixing surface of the rear tripod through the tightening ring, one end of the limiting strip can be fixed on the fixing surface through a screw and a group of gaskets, the height of the limiting mechanism can be adjusted conveniently, the middle pipe can be limited, and the vibration amplitude can be adjusted.
