The distance adjusting device comprises a rotating shaft and a sleeve, wherein the rotating shaft 13 is connected with an adjusting part, the sleeve 16 is connected with a fixing part, the adjusting part and the fixing part are not distinguished from each other in absolute position, and the adjusting part and the fixing part move oppositely during adjustment.
Wherein, the regulating part is located in the rotation of the one end of pivot 13, and the two axial joint is spacing, consequently at the pivot 13 in the rotation process for the regulating part, the two is relatively fixed in the axial of pivot 13, therefore pivot 13 can be used for driving the regulating part and carry out axial displacement.
The sleeve 16 is sleeved outside the rotating shaft 13 and can relatively rotate in the circumferential direction to form the sleeve cam mechanism 7. One end of the sleeve 16 is secured to the fastener to form a fixedly attached unitary structure. The sleeve 16 or the fixed member is provided with a rotation restricting portion 11 for restricting the relative rotation thereof with the adjusting member, for example, the sleeve 16 may be provided with an axially movable guide member for achieving the axial movement guide and restricting the relative rotation between the sleeve 16 and the adjusting member.
One of the sleeve 16 and the rotating shaft 13 is provided with a groove 131 which extends along the axial direction and is continuous along the circumferential direction, and the other one is provided with a convex part which is arranged in the groove 131 in a sliding way; when the rotating shaft 13 rotates unidirectionally, the sleeve 16 performs an axial reciprocating motion with respect to the rotating shaft 13.
Taking the sleeve 16 with the protrusion, the rotating shaft 13 with the groove 131 as an example, and the adjusting member as a reference of the spatial position, during the rotation of the rotating shaft 13, the rotating shaft 13 only rotates relative to the adjusting member, the protrusion slides in the groove 131, and since the groove 131 is circumferentially continuous, a closed loop is formed, and has an axial extension, the protrusion can move relative to the axial direction of the rotating shaft 13 when sliding in the groove 131. The protruding portion is fixedly connected with the sleeve 16, and the sleeve 16 is provided with the rotation limiting portion 11, so that the sleeve 16 and the rotating shaft 13 form a screw rod structure, the sleeve 16 can only move along the axial direction under the driving of the protruding portion, and then the fixing member fixedly connected with the sleeve 16 is driven to move relative to the adjusting member along the axial direction, so that the fixing member and the adjusting member move relatively in the axial direction, and the circumferential relative rotation is avoided.
The grooves 131 may be corrugated grooves or saw-tooth grooves arranged along the circumferential direction, and have at least one wave crest and one wave trough in the circumferential direction, because the grooves 131 are continuous in the circumferential direction, so that the rotating shaft 13 can be continuously rotated during operation, and after reaching the maximum position, the distance can be reduced by continuing to rotate. Moreover, the distance between the fixing piece and the adjusting piece can be adjusted to be larger or smaller in a clockwise or anticlockwise mode.
It should be noted that the range of the linear movement of the sleeve 16 depends on the maximum range of the fluctuation of the groove 131 in the axial direction.
