Further, in order to avoid that the output rotation body 5 collides with the casing when moving on the output shaft 4 due to being screwed out of the range of the spiral groove, the third limiting structure 43 may further include another snap spring disposed at a joint of the output shaft 4 located in the casing and close to the casing, and the snap spring may also be fastened and fixed by a snap groove formed on the output shaft 4, it can be understood that the specific form of the third limiting structure 43 may also be other, for example, a protruding structure formed on the output shaft 4, and the protruding structure may be integrally formed with the output shaft 4, or may be fixed together with the output shaft 4 by welding or the like, or may be detachably connected by screwing, inserting or the like.

Further, with reference to fig. 1 to 4, in order to enable the driven rotation body 7 to achieve different operating states of the output shaft 4 according to different steering engagements. The driven rotor 7 includes a first sub-driven rotor 71, and the first sub-driven rotor 71 is always drive-coupled to the input rotor 3. The driven rotary body 7 needs to be moved along the driven shaft 6 to be coupled with or decoupled from the output rotary body 5 to achieve operation of the output shaft 4 in different operating states. In the present embodiment, the first sub-driven rotation body 71 is coupled by transmission with the input rotation, and thus can change the operation direction synchronously when the input shaft 2 operates in the first direction or in the reverse direction opposite to the first direction. In one embodiment, the first sub-driven rotator 71 can have a length that ensures the driving force transmitted by the input rotator 3 that is always received when moving on the driven shaft 6 to be separated from or coupled to the output rotator 5.

The first sub-driven revolving body 71 is always in transmission coupling with the input revolving body 3, so that the driven shaft 6 can run along with the running direction of the input shaft 2, and the second sub-driven revolving body 72 can move up or down along the driven shaft 6 to be coupled with or separated from the output revolving body 5 when the driven shaft 6 rotates in different directions, so that the output of the output shaft 4 along the paths of the input shaft 2, the input revolving body 3, the first sub-driven revolving body 71, the driven shaft 6, the second sub-driven revolving body 72, the output revolving body 5 and the output shaft 4 is realized; or, the input shaft 2, the input rotator 3, the first sub-driven rotator 71, the driven shaft 6; and a path output of the input shaft 2, the input rotator 3, the first coupling part 32, the second coupling part 52, and the output shaft 4.

Alternatively, the transmission effect is good for the driven rotation body 7. The first sub driven rotation body 71 is fixedly connected to the second sub driven rotation body 72. The second sub-driven revolving body 72 and the first sub-driven revolving body are fixed or arranged in a separated mode, so that the second sub-driven revolving body 72 can move along the driven shaft 6, but it is understood that under the condition that the first sub-driven revolving body 71 and the second sub-driven revolving body 72 are fixed, the second sub-driven revolving body 72 can be driven by the first sub-driven revolving body 71 to be stable and ensure the coupling and separation processes regardless of the transmission coupling with the output revolving body 5 or the separation with the output revolving body 5. The first sub driven rotation body 71 and the second sub driven rotation body 72 can be fixed in various ways, for example, the first sub driven rotation body 71 and the second sub driven rotation body 72 are integrated, or the first sub driven rotation body 71 and the second sub driven rotation body 72 are connected by welding, or the first sub driven rotation body 71 and the second sub driven rotation body 7 are fixed by fasteners, etc.

As shown in fig. 5 to 7, in the embodiment where the driven rotation body 7 is a gear, the driven rotation body 7 may be a structure of a driven double gear and a one-way gear 8, that is, a double driven gear has a lower gear 73 and an upper gear 74, the lower gear 73 is fixed with the upper gear 74 or is connected with the one-way gear 8, for example, the fixing is realized by a way of an elastic pressing sheet in a one-way tooth slot in the middle of a disk, so as to avoid the locking when being coupled with the output rotation body 5.

Alternatively, in order to realize the movement of the driven rotation body 7 on the driven shaft 6, one of the driven shaft 6 and the driven rotation body 7 is formed with a third spiral groove 61 extending in the axial direction thereof, and the other of the driven shaft 6 and the driven rotation body 7 is formed with a third guide projection fitted into the spiral groove, the third guide projection interacting with the third spiral groove 61 to drive the driven rotation body 7 to move in the axial direction of the driven shaft 6. In one arrangement mode, the driven shaft 6 is provided with the third spiral groove 61, and the inner wall of the output revolving body 5 is provided with a third guide protrusion, wherein the third spiral groove 61 extends in the axial direction of the driven shaft 6 for a certain length, the third guide protrusion can also be spiral and provided with multiple sections, during the operation process, when the input shaft 2 rotates in the first direction, the input revolving body 3 rotates along with the input shaft 2, the input revolving body 3 drives the driven revolving body 7 to rotate and move along the driven shaft 6 because of being in transmission coupling with the driven revolving body 7, and when the driven revolving body 7 is in transmission coupling with the output revolving body 5, the driven revolving body 7 drives the output revolving body 5 to rotate, so that the output revolving body 5 can drive the driven shaft 6 to rotate; when the input shaft 2 moves in the opposite direction of the first direction, the driven rotating body 7 moves in the opposite direction of the driven shaft 6, and the driven rotating body 7 drives the output rotating body 5 to move along the output shaft 4, so that the first coupling part 32 and the second coupling part 52 are coupled.

It should be noted that, other embodiments can be adopted to realize the movement of the input revolving body 3 on the input shaft 2, the movement of the driven revolving body 7 on the driven shaft 6, and the movement of the output revolving body 5 on the output shaft 4, for example, in one embodiment, the movement purpose can be realized by means of an electromagnet, and the movement target can be realized according to the requirement, for example, an electromagnet is installed on the surface of one end of the driven shaft 6 or the casing, or the driven revolving body 7, so that under the condition of the connection of different currents, the electromagnet generates forces in different directions to realize the effect of repulsion and attraction on the driven revolving body 7, and drives the driven revolving body 7 to move between the first position and the second position on the driven shaft 6. It is understood that in the case of such a structural arrangement, the cross-sectional shape of the portion of the driven shaft 6 to which the driven rotator 7 is attached should be such as to limit the driven rotator 7 to be movable only in the axial direction of the driven shaft 6, and not to allow the driven rotator 7 to rotate in the circumferential direction relative to the driven shaft 6, and for this reason, the cross-sectional shape of the portion of the driven shaft 6 to which the driven rotator 7 is attached may be provided in a D-shape, a polygonal shape, or a special-shaped structure, for example. In another structure, the moving mode of the driven rotator 7 on the driven shaft 6 may be a shifting lever structure installed on the housing, the shifting lever structure has a driving end protruding out of the housing and an actuating end contacting with the driven rotator 7, a user can manually press the driving end, so that the shifting lever structure transmits power to the actuating end in a lever principle mode to shift the driven rotator 7 to move along the driven shaft 6, of course, the power source of the driving end may also be provided by other electrical components, such as driving by other motors, or driving by an air cylinder, and the like, and similarly, in the case of adopting the shifting lever structure, the cross-sectional shape of the part of the driven shaft 6 where the driven rotator 7 is installed should be such that the driven rotator 7 can only move along the axial direction of the driven shaft 6, but cannot make the driven rotator 7 rotate in the circumferential direction relative to the driven shaft 6, it is to be understood that the form of the present application in which the input rotary body 3 moves on the input shaft 2, the driven rotary body 7 moves on the driven shaft 6, and the output rotary body 5 moves on the output shaft 4 is not limited to the two forms listed above, and a non-contact driving form in which the driven rotary body 7 slides along the driven shaft 6 by blowing air, for example, or other feasible forms may be adopted. Accordingly, please refer to the above contents for the specific manner of the input rotator 3 moving on the input shaft 2 and the output rotator 5 moving on the output shaft 4, which will not be described herein. That is, in the present embodiment, the idea of moving the input rotary body 3 on the input shaft 2, moving the driven rotary body 7 on the driven shaft 6, and moving the output rotary body 5 on the output shaft 4 is that the stroke is more easily controlled by driving the driven rotary body 7 in the axial direction of the driven shaft 6 by applying an external force by the driving member as a driving member of a third party.

Alternatively, referring to fig. 1 to 4, in order to improve structural stability, the driven shaft 6 is provided with a first stopper structure 62 at a first position, the first stopper structure 62 being for preventing the second sub driven rotation body 72 from being rotated out of the third spiral groove 61. The first limiting structure 62 is disposed at an end of the driven shaft 6 close to the output shaft 4, wherein the specific form of the first limiting structure 62 may refer to the form of the third limiting structure 43, and will not be described herein again.

Alternatively, the driven shaft 6 is provided with a second stopper structure 63 at the second position, the second stopper structure 63 being for preventing the first sub driven rotation body 71 from being unscrewed out of the third spiral groove 61. The second limiting structure 63 is disposed at an end of the driven shaft 6 close to the input shaft 2, wherein the specific form of the second limiting structure 63 may refer to the forms of the second limiting structure 63 and the third limiting structure 43, and details are not repeated here.

Alternatively, the rotational speed at which the output shaft 4 operates in the first state is lower than the rotational speed at which it operates in the second operating state, and the torque at which it operates in the first state is higher than the torque at which it operates in the second operating state. The output shaft 4 operates in a first state at a lower speed than in a second state, and the first state operates at a higher torque than in the second state. Thus, when the output shaft 4 is operated in the second state, the output shaft outputs at a lower rotating speed and a larger torque, and the output with different transmission ratios can be realized, and different scenes can be applied due to different rotating speeds and torques.
