Detection device convenient to carry

The utility model provides a portable detection device, relates to the technical field of medical detection devices, and aims to solve the problem that although an existing asthenopia detection device can emit infrared detection light to the eyes of a subject through an infrared emitter to detect and calculate the blinking frequency of the subject, the blinking frequency of the subject cannot be detected and calculated. However, when infrared detection light irradiates the eyes of the subject for a long time, the eyes of the subject are hurt. A window frame is installed on the upper end face of the base, a rotating connecting block is fixedly connected to the middle of the top end face of the window frame, a rotating rod is rotationally connected to the inner side of the rotating connecting block, and a limiting mechanism is installed on the right end face of the rotating connecting block. Through the cooperation of the camera and the touch screen computer, infrared detection light does not need to be emitted
