running shaft 26, thus drive all clutch connecting lever foot pieces 28 and magnetic to scold block 25, when clutch connecting lever foot piece 28 is pulled up to several angle, the clutch connecting lever trundle 21 of scolding block 25 to be connected by clutch connecting lever 23 with magnetic has on the side of groove 20 side, passive free wheel side by abutting in passive free wheel 10, and clutch connecting lever trundle 21 is scratched rotation on passive free wheel 10 side, when clutch connecting lever trundle 21 be scratched rotate to passive free wheel side groove 20 time, magnetic repulsion one due to half drum magnetic shoe 16 reprimands the half magnetic that press against passive arbor wheel 8 excircle and scolds block 25 and make the rotation of clutch connecting lever trundle 21 snap in passive free wheel side groove 20, thus make passive free wheel 10 mesh together rotation with passive arbor wheel 8, because the outer gear teeth 19 of the passive free wheel of passive free wheel 10 engage with the outer gear teeth 17 of the driving wheel of the driving wheel 7 on driving shaft 2 always, passive free wheel 10 is rotated with linear velocity with driving wheel 7, passive arbor wheel 8 is then rotated with angular velocity with the spring force drive of right spring 12 by left spring 5 together with driven axle 1, due to the action character of spring force, the rotation of passive arbor wheel 8 has certain non-rigid feature, so, when the magnetic that the magnetic repulsion one of half drum magnetic shoe 16 reprimands the half quantity that press against passive arbor wheel 8 excircle is scolded block 25 and is made clutch connecting lever trundle 21 rotate to snap in passive free wheel side groove 20, the rotational speed of passive free wheel 10 and the rotational speed of passive arbor wheel 8 different, but under difference is no more than the condition of 25%, clutch connecting lever trundle 21 can be easily, snap in passive free wheel side groove 20 rapidly, thus make the rotational speed of passive free wheel 10 reach the same with the rotational speed of passive arbor wheel 8, realize the closure function in clutch process, at passive arbor wheel 8 with passive free wheel 10 closing course, namely move closer in the rotational speed of passive arbor wheel 8 in the rotational speed process of passive free wheel 10, and that make passive arbor wheel 8 on driven axle 1 do relative to driven axle 1 rotation different with driven axle 1 rotational speed because speed changes of passive arbor wheel 8, and by the left spring 5 on the left of force transmission to passive arbor wheel 8 and the right spring 12 on the right side of passive arbor wheel 8, the rotational speed of passive arbor wheel 8 is made to move closer to the rotational speed of driven axle 1, rotational speed and the rotational speed of passive arbor wheel 8 of passive free wheel 10 reach the same after, passive arbor wheel 8 overcomes making a concerted effort of the active force of the right spring 12 on the right side of the active force of the left spring 5 on the left of passive arbor wheel 8 and passive arbor wheel 8, on left buffering wheel 4 right flank that left accessory whorl 6 left surface on the left of passive arbor wheel 8 is abutted on the left of passive arbor wheel 8, thus make passive arbor wheel 8 relative fixing with driven axle 1 position, and then realize passive arbor wheel 8 and rotate with angular velocity with driven axle 1, or on right buffering wheel 13 left surface that right accessory whorl 9 right flank on the right side of passive arbor wheel 8 is abutted on the right side of passive arbor wheel 8, thus make passive arbor wheel 8 relative fixing with driven axle 1 position, and then realize passive arbor wheel 8 and rotate with angular velocity with driven axle 1, complete the closed synchronous overall process in clutch process thus, when the lower limb that half drum magnetic shoe 16 moves apart passive arbor wheel 8 to half drum magnetic shoe 16 is on the upside of passive free wheel 10, half drum magnetic shoe 16 pairs magnetic scolds the magnetic of block 25 to scold active force to disappear, make clutch connecting lever 23 because being arranged on the effect of the spring-return power of the clutch connecting lever lower spring 24 under clutch connecting lever 23, be returned to clutch connecting lever 23 and become a α horn shape state with passive arbor wheel 8 excircle, thus make clutch connecting lever trundle 21 leave passive free wheel side groove 20, and then passive free wheel 10 is only connected and each spinning by one group of bearing 18 with passive arbor wheel 8, complete the separation process in clutch process.
