Kind Code:
A1
Abstract:
The present application relates to the technical field of lenses, and in particular to a focusing device, comprising: a lens assembly, a first motor, a second motor, and a motor control panel. The lens assembly comprises a lens; the first motor and the second motor are respectively provided on two opposite sides of the lens assembly; the motor control panel is fixedly provided on one side of the lens assembly. The motor control panel controls synchronous rotation of the two motors located on the two sides of the lens assembly, thereby increasing the thrust of the motors, keeping the lens stationary in motion, and avoiding tilting. Moreover, use of two small motors can effectively reduce the overall machine size.
