As shown in the attached figure 1, the strip-shaped object telescopic profiling system comprises a fluid passage, wherein a strip-shaped object 1, a reciprocating mechanism 4, a pressure proportional valve 2 and a flow proportional valve 3 are arranged on the fluid passage; the reciprocating mechanism 4 is controlled by the fluid of the fluid passage, the reciprocating mechanism 4 can be a device such as an air cylinder or a hydraulic cylinder, and the air cylinder or the hydraulic cylinder can adopt a single-pass or double-pass mode; the telescopic working end of the reciprocating mechanism 4 is matched with one end of the bar-shaped object 1, and the other end of the bar-shaped object 1 is fixed.
