1. A multi-diameter clipping mechanism, comprising:
an adhesive member, having an adhesive surface and a mount surface opposite to the adhesive surface, in which the adhesive surface is configured to be affixed to a nasal bridge of a patient in a reusable manner, the mount surface of the adhesive member is provided with a pivot seat;
a connecting member, having one end thereof connected to the mount surface of the adhesive member, in which the connecting member has one end thereof provided with a first ball head, so that the first ball head is rotatably received in the pivot seat;
a first clipping member, connected to the connecting member, the first clipping member being formed with a guiding trough at one side therethrough and being provided with a resilient arm that is near the guiding trough;
a second clipping member, having one end thereof pivotally connected to an opposite side of the first clipping member, and having an opposite end thereof provided with an engaging tongue that has an outer edge provided with a plurality of unidirectionally inclined teeth; and
an engaging member, pivotally connected to the side of the first clipping member that has the guiding trough and is opposite to the second clipping member, the engaging member having one end thereof provided with an engaging salient, and having an opposite end thereof provided with a press portion, in which when the second clipping member has entered the guiding trough by pivoting with respect to the first clipping member, one of the unidirectionally inclined teeth of the engaging tongue engages with the engaging salient, and when the press portion is pressed against the resilient arm by an external force, the engaging member pivots with respect to the first clipping member to disengage the engaging salient from the currently engaged unidirectionally inclined tooth, thereby making the second clipping member sway outward and leave the guiding trough.
