In order to achieve the above object, the utility model comprises sleeve, eccentric shaft, fluctuating sliding shoe, fluctuating shifting block and latch, the fluctuating pull plate, fluctuating pull bar screw is replied control setup, locating piece, wherein, offer eccentric through-hole on the sleeve, be provided with axial dead slot by the middle part of eccentric through-hole on the sleeve, the fluctuating sliding shoe is contained in the axial dead slot and flexibly connects with an end of fluctuating shifting block, eccentric shaft passes in the fluctuating sliding shoe and passes eccentric through-hole, be fixed with locating piece on the eccentric shaft, eccentric shaft is the pipe of hollow, and its middle part offers axial pass trough, be provided with the fluctuating pull plate in the groove, the extended groove in the both sides of fluctuating pull plate, fluctuating pull bar screw is contained in the pipe of eccentric shaft hollow, and the one end is connected with the fluctuating pull plate, the other end is connected with the answer control setup, and the middle part of fluctuating shifting block flexibly connects by latch and sleeve.
Further improve, described answer control setup comprises retracing spring, block and bolt and nut, block is fastened on the described fluctuating pull bar screw, retracing spring is enclosed within on the fluctuating pull bar screw, one end is spacing by link stopper, and the other end compresses by the bolt and the nut of hollow, and suitable gap is arranged in fluctuating pull bar screw and bolt and the nut.
Preferably, described eccentric shaft is connected together by bearing carrier ring with the fluctuating sliding shoe and passes eccentric through-hole on the sleeve.
As further improving, describedly be equiped with cover plate respectively at the sleeve two ends, on the cover board have and cooresponding hole, eccentric through-hole position.
Because the fluctuating shifting block can make wheel hub and eccentric shaft assembly relative fixed for axle rotates by latch, so the wheel shaft stress equalization.The present invention also has compact conformation, is easy to the beneficial effect of processing and assembling.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the eccentric assembly of eccentric shaft bicycle of the present utility model comprises sleeve 14, eccentric shaft 3, fluctuating sliding shoe 2, fluctuating shifting block 8 and latch 7, fluctuating pull plate 32, fluctuating pull bar screw 31 is replied control setup B, locating piece 6.
Wherein, as Fig. 6 and shown in Figure 2, offer eccentric through-hole 18 on the sleeve 14, middle part by eccentric through-hole 18 on the sleeve 14 is provided with axial dead slot 16, fluctuating sliding shoe 2 is contained in the axial dead slot 16 and by the ends of holding screw 13 with fluctuating shifting block 8 and flexibly connects, make fluctuating shifting block 8 can be with the slip of fluctuating sliding shoe 2 rotating certain angle.
Fluctuating pull bar screw 31 is contained in the pipe of eccentric shaft 3 hollows, and the one end is connected with fluctuating pull plate 32, and the other end is connected with answer control setup B.
