The roller 5 is arranged between the radial outer side of the retainer 8 and the outer ring 1 at intervals and can rotate relatively; the roller 5 and the retainer 8 adopt a magnetic suspension type rolling matching mode, and can also adopt contact type sliding or rolling; the cage 8 is not in contact with the inner ring 9 on the radially inner side or is rotationally connected thereto, including but not limited to contact sliding, rolling with rollers or magnetic levitation with magnetic material. The double-link block 3 inclines towards the clockwise direction, and the radial size of the double-link block can be inversely related to the change of the included angle of the long axis of the double-link block relative to the radial direction; when the outer ring 1 rotates clockwise relative to the inner ring 9, the rollers 5 roll in the same direction, so that the double-link blocks 3 tilt clockwise and the radial size is reduced, when the outer ring reaches a limit position, the double-link blocks 3 and the outer ring 1 can be in non-contact or non-pressure contact because the rollers 5 bear the pressure of the outer ring 1, and the clutch is in an overrunning state, at the moment, the rollers 5 are limited by the double-link blocks 3 in the circumferential motion, but still rotate under the friction action of the outer ring 1; when the outer ring 1 rotates anticlockwise relative to the inner ring, the double-link block 3 tilts anticlockwise and the radial size gradually increases until the outer ring 1 and the inner ring 9 can be locked through two end points or the outer ring 1 and the inner ring 9 can be locked through one end point and the pin shaft 4 instead of the roller 5 bearing the pressure of the outer ring 1. The double-link block 3 can be one, or more than two blocks can be distributed in the circumferential direction, and the blocks are uniformly inclined towards one direction to realize unidirectional locking or separation, or the blocks are divided into two groups and are respectively inclined towards the opposite direction to realize bidirectional locking.

The double-link block 3 of the embodiment of fig. 1 is a friction type locking element, the outer ring 1 and the inner ring 9 are locked by two end points of a long shaft, or the outer ring 1 and the inner ring 9 are locked by one end point and a pin shaft 4, a tooth shape can be arranged on the end points, and meanwhile, racks which can be meshed with the outer ring 1, the clutch seat, the inner ring 9 or the middle shaft 10 for transmission are also arranged on the outer ring 1, the clutch seat, the inner ring 9 or the middle shaft 10.
Referring to the embodiment of fig. 4, a plurality of friction blocks 14 are provided, and both ends of each friction block are respectively and rotatably connected with the adjacent couple blocks 3, so that when the relative speed of the outer ring 1 and the inner ring 9 changes, the radial size of the couple blocks 3 also changes, and the friction blocks 14 are driven to approach or separate from the outer ring 1, thereby realizing the locking or the separation of the clutch. Referring to the embodiment shown in fig. 5, the flexible ring 15 is wound around the central shaft 10, and both ends of the flexible ring are respectively rotatably connected with both ends of the dual-linkage block 3, and the radial dimension change of the dual-linkage block 3 enables the flexible ring 15 to hold or release the central shaft 10, thereby realizing the locking or the separation of the clutch.

Referring to fig. 1 and 2, an elastic material is arranged between the far end of the oblong hole 2 and the pin shaft 11, so that the double-link block 3 is subjected to pre-pressure tilting towards the locking direction when in an overrunning state, and the pre-pressure is smaller than the force required for maintaining the overrunning state, thereby preventing the locking function from being failed when the roller 5 slips accidentally.
Refer to fig. 1 and 10. Fig. 10 shows an eccentric wheel type inclination adjusting mechanism, in which an eccentric wheel 25 is fixed on a pin 11, the eccentric direction of the eccentric wheel is changed to change the maximum sliding stroke of a duplex block 3 and the pin 11, and the acting point of the eccentric wheel 25 on the inner wall of the oblong hole 2 is in the radial position, and the eccentric direction of the eccentric wheel 25 is changed to enable the tilting degree of the duplex block 3 to have different sensitivities to the circumferential displacement of the pin 11, so that the tilting angle, namely the slip angle, of the duplex block 3 between a locking state and an overrunning state can be adjusted under the condition that the distance between the pin 4 and the pin 11 is determined, and therefore, the wear compensation or other functions of a transmission part can be adjusted. The technical type of tilt adjustment mechanism is not limited to eccentric circle mechanisms and may include, but is not limited to, rocker arms, linkages, pull wires, worms, threads, electrical, pneumatic, hydraulic or magnetic mechanisms.
