Problems solved by technology
[0002] In the prior art, manual continuous linkage lenses are widely used in various measurement environments, and the magnification value of the lens is mainly read manually. On the one hand, it is easy to misread the lens magnification value; on the other hand, when the lens needs to be adjusted, Manually read the current magnification value of the lens first, and then select the corresponding magnification parameter in the software. This operation method is not only low in work efficiency, but also prone to errors and low in accuracy.
Due to the large reflective surface of the existing reflective electronic feedback device, its accuracy cannot meet the needs of use, and the anti-electromagnetic interference is weak. However, the existing Hall induction type has misjudgment due to external magnetic field interference, resulting in a magnification recognition error

The invention discloses a magnification feedback lens based on a variable resistance form. The lens comprises an outer cylinder, an eyepiece assembly is fixed at the upper end of the outer cylinder; an objective lens assembly is fixed at the lower end of the outer cylinder; the ocular lens assembly and the objective lens assembly are fixedly connected through an inner lens cone. The inner lens cone is movably connected with a zoom linkage assembly, the zoom linkage assembly comprises a rotating assembly which is rotatably arranged outside the inner lens cone in a sleeving mode, a signal feedback assembly is arranged at the upper end of the rotating assembly, and the signal feedback assembly moves up and down to feed back and output the magnification of the zoom linkage assembly in a variable resistance mode. According to the invention, the multiplying power is fed back and output in a variable resistance form, and the multiplying power feedback precision and the anti-electromagnetic interference capability are improved.
