摘要： The invention discloses an X-ray zoom lens system (Transfocator) and a focus variation method. The system is characterized in that it includes a main frame, many switched arms arranged on one side of the main frame, and a driving component set at the top of the main frame, and a positioning groove set at the bottom of the main frame; For them, each switched arm is composed of successively connected a push rod, a push-push ratchet mechanism, a preload spring and a guide stick, two-dimensional flexible axis, and a CRLs holder from top to bottom; CRLs are stacked and arranged in the mentioned above CRLs holder; The push-push ratchet mechanism contains that an extension spring, a slider with ratchet guide slot, a guide baseplate, a C-shaped tie rod, in which the slider with ratchet guide slot and the guide baseplate form a linear guide motion pair by a linear groove and a guide structure. The upper end of the slider with ratchet guide slot is connected to the upper end of the guide plate by the extension spring; The lower end of the slider with ratchet guide slot is successively connected with the preload spring and guide stick, the two-dimensional flexible axis, and the CRLs holder; The upper end of the C-shaped tie rod is used to slide in the ratchet guide slot of the slider with ratchet guide slot, and its lower end is connected with the bottom end of the guide baseplate by an elastic clamping.
