Abstract:
1. A pivotally connected structure allowing lens replacement and lens angle adjustment, comprising: a positioning frame formed as a hollow circular frame, the positioning frame having an end provided with a positioning ring protruding in an axial direction of the positioning frame, the positioning ring having an outer periphery provided with threads threadedly connectable with threads provided on a front side of a camera lens, so as to position the positioning frame on the front side of the camera lens, the positioning frame having an inner periphery which is adjacent to an opposite end of the positioning frame and is provided with a pivotally connecting groove; a pivotally connecting frame formed as a hollow circular frame, the pivotally connecting frame having an end provided with a pivotally connecting ring protruding in an axial direction of the pivotally connecting frame, the pivotally connecting ring having an outer periphery provided with a pivotally connecting flange, wherein the pivotally connecting flange and the pivotally connecting groove are engageable, and pivotally connectable, with each other due to elasticity and deformability of the pivotally connecting frame and of the positioning frame, the pivotally connecting frame being provided therein with a receiving space corresponding in position to a hollow portion of the pivotally connecting frame, the receiving space being configured for receiving a lens mounted therein, the pivotally connecting frame having an opposite end provided with a first engaging ring protruding in the axial direction of the pivotally connecting frame, the first engaging ring having an inner periphery formed with a first curved surface extending in an axial direction of the first engaging ring, the first engaging ring having an inner diameter greater than an inner diameter of the pivotally connecting frame that corresponds to the receiving space; and an engaging frame formed as a hollow circular frame, the engaging frame having an end provided with a pressing ring protruding inward in a radial direction of the engaging frame, the engaging frame having an outer periphery formed with a second curved surface extending in an axial direction of the engaging frame, wherein the second curved surface and the first curved surface are engageable, and pivotally connectable, with each other due to elasticity and deformability of the engaging frame and of the pivotally connecting frame, so as for the pressing ring to directly press against a periphery of the lens or press the periphery of the lens indirectly, thereby positioning the lens in the receiving space, the engaging frame having an opposite end provided with a second engaging ring protruding outward in the radial direction of the engaging frame, the second engaging ring being configured for pressing against a periphery of the first engaging ring.
