Abstract: A switchable high and low magnification lightweight microscope lens structure has a first microscope unit, a second microscope unit and a hinge. The first microscope unit has a first microscope lens having a first adhesive piece adhesively attached to an inner side of the first microscope unit with a hole formed through the first adhesive piece. The second microscope unit has a second microscope lens with a magnification higher than that of the first microscope lens having a second adhesive piece adhesively attached to an inner side of the second microscope unit. The hinge has two fixed arms, a pivoting block and a pivoting pin. The fixed arms are formed on and protrude from one edge of the first microscope unit. The pivoting block are formed on and protrudes from one edge of the second microscope unit, and mounted between the fixed arms.

Abstract: A movable and replaceable lens structure for electronic devices has a lens-mounting body mounted on and electrically connected with a electronic device, and a movable lens module mounted on the lens-mounting body and having a movable mechanism mounted on the lens-mounting body or a housing of the electronic device. The movable lens module has a movable mechanism mounted on the lens-mounting body or the housing of the electronic device. A lens is connected with the movable mechanism. An operation part is connected with the movable mechanism. The movable mechanism can be operated to move along a straight line, rotate or pivot, thereby moving the lens to align with an optical axis of the movable lens module and varying the focus of field of view of the movable lens module. Accordingly, the lens with different picture-taking effect can be provided, such as a wide-angle, microscopic or telescopic lens.

Abstract: A portable high-power microscope magnification lens structure, mainly comprises: a main body, a high-power lens being disposed on a middle part thereof which is passed through, an adhesive portion being disposed on a rear edge of the main body, LED lamps used for light compensating illumination being disposed around the lens on a front side of the main body; and a rear cover, one side thereof being pivotally connected to the main body, the rear cover being foldable to cover a rear side of the main body, and a hollow space for receiving batteries being disposed on the rear cover and connected to the LED lamps through a switch; whereby, the additional unit can be attached to the lens of a cellular phone, tablet or camera, used to shoot and observe high-power microscopically magnified images, used as the teaching assistance for the observation of organisms or physical objects, and used for the microscopic magnification photography of the details of other industrial product structures, and the pictures taken from
