Clutch external operation (clutch in non-clutched state):
when the clutch base rotates clockwise, four contacts on the base are in contact with the upper shifting fork to enable the clutch base to rotate clockwise, the upper shifting tooth sheet, the lower shifting fork and the contacts on the clutch base have rotation angle difference and cannot rotate, after the clockwise work is finished, the upper shifting fork returns to the initial position due to the action of a spring on the latch bolt component, and the upper shifting fork in the return state drives the clutch base to return to the reference position;
when the clutch base anticlockwise rotates, the contact on the base simultaneously contacts with the upper shifting tooth piece and the lower shifting fork, so that the upper shifting fork and the lower shifting fork simultaneously anticlockwise rotate, the contact on the upper shifting fork and the clutch base is rotated by a rotating angle difference, the contact on the upper shifting fork and the contact on the clutch base can be kept static, and after the anticlockwise operation is finished, the lower shifting fork and the clutch base can return to the initial reference position under the action of the lower shifting fork reset tension spring.
Therefore, the clutch base can always be ensured to return to the reference position by rotating.
Clutch inner operation (second step on outer turntable on right side of slope):
when the outer rotating disc rotates anticlockwise, the outer rotating disc is contacted with the clutch base, and the clutch base and the outer rotating disc rotate anticlockwise together; when the outer rotating disc rotates clockwise and the clutch pin is not retracted into the clutch base, the outer rotating disc idles, and because the slope surface on the clutch base is lower than the step surface of the second step of the outer rotating disc, the outer rotating disc rotates clockwise, moves outwards for a certain stroke along the axial direction and then continuously idles; when the outer rotating disc rotates clockwise and the clutch pin retracts into the clutch base under the action of the driving part, the clutch base and the outer rotating disc rotate together in the same direction; the four convex steps of the inner rotary disc are positioned together with the four grooves in the clutch base, so that the clutch base always keeps rotating in the same direction as the inner rotary disc.
When the inside and outside direction of the clutch needs to be changed, the inside and outside direction can be changed only by directly adjusting the positions of the outer rotating disc and the inner rotating disc.
At the moment, when the outer rotating disc rotates anticlockwise, the outer rotating disc is in contact with the clutch base, and the clutch base and the outer rotating disc rotate anticlockwise together; when the outer rotating disc rotates clockwise and the clutch pin is not retracted into the clutch base, the outer rotating disc idles, and then the outer rotating disc rotates clockwise while moving outwards for a certain stroke along the axial direction and then continuously idles because the slope surface on the clutch base is lower than the step surface of the second step of the outer rotating disc; when the outer rotating disc rotates clockwise and the clutch pin retracts into the clutch base under the action of the driving part, the clutch base and the outer rotating disc rotate together in the same direction; the four convex steps of the inner rotary disc are positioned together with the four grooves in the clutch base, so that the clutch base always keeps rotating in the same direction as the inner rotary disc.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
