Further, referring to fig. 8, the driving force output portion 40 further includes, for example: a driving force transmission surface 45. The driving force transmission surface 45 and the second anti-stop surface 44 are provided in the same plane, and the second anti-stop surface 44 is provided around the driving force transmission surface 45. A groove, namely a first matching position 46, is arranged on the driving force transmission surface 45 at a position corresponding to the first direction driving position 24; a groove, i.e., a second matching bit 47, is formed on the driving force transmission surface 45 at a position corresponding to the second direction driving bit 26. Preferably, the needle roller 23 is provided with a spherical structure, for example, and the first mating site 46 and the second mating site 47 may be concave cambered grooves matched with the spherical structure.
For example, when the needle roller 23 is located at the first direction disengaging position 25, the elastic member 42 is in an elastic stretching state, so that the second anti-stop surface 44 is also in an elastic stretching state and is in non-return fit with the first anti-stop surface 31 through the clamping groove, when the end of the driving force output portion 40 away from the driving force receiving portion 10 receives a driving force in any direction, for example, the first anti-stop surface 31 and the second anti-stop surface 44 are in non-return fit and fixed with each other, the driving force output portion 40 cannot rotate along with the driving force; when the needle roller 23 is located at the first direction driving position 24, that is, when the driving force receiving portion 10 obtains torque, the needle roller 23 is interposed between the first direction driving position 24 and the first mating position 46, the elastic member 42 is in an elastically compressed state, so that the second anti-stop surface 44 is also in an elastically compressed state, and at this time, the second anti-stop surface 44 is separated from the first anti-stop surface 31, so that the driving force output portion can rotate. The first direction driving position 24 and the first direction disengaging position 25 are both sinking grooves formed in one side of the control member 21 close to the driving force output part 40, and the depth of the first direction disengaging position 25 is greater than that of the first direction driving position 24; therefore, when the needle roller 23 is positioned at the first direction driving position 24, the check member 41, the control member 21 and the control sleeve 22 are matched to clamp the needle roller 23 between the first matching position 46 and the first direction driving position 24; when the needle rollers 23 are located at the first direction disengaging position 25, a gap is formed between the first matching position 46 and the needle rollers 23, that is, the check member 41 is not in contact with the needle rollers 23. Of course, the above function can be achieved when the needle roller 23 is located at the second direction driving position 26 or the second direction disengaging position 27, which is not described in detail herein.
