Abstract:
A support structure, which supports a driving shaft (10) performing reciprocating motion. The support structure (20) comprises an inner fixing ring (23) of the support structure, at least one elastic member (22) of the support structure, and an outer fixing ring (21) of the support structure; the inner fixing ring (23) of the support structure is fastened on the driving shaft (10); the outer fixing ring (21) of the support structure is fastened on an inner wall of a lower device housing; the elastic member (22) of the support structure is provided between the outer fixing ring (21) and the inner fixing ring (23) of the support structure; and on the cross section of the elastic piece (22) of the support structure perpendicular to the radial direction of the driving shaft (10), the width (b1) in the direction perpendicular to a driving force (F1) is three times larger than the thickness (t1) in the direction parallel to the driving force (F1). The support structure (20) has the advantages of being low in noise, low in energy loss, low in cost, simple in structure, and suitable for batch production.
