The invention relates to a portable reflective film collector. The portable reflective film collector comprises a multistage stretchable rod and a plurality of grippers. An innermost-layer rod body is sleeved with a baffle ring, the end, close to the tail end of the innermost-layer rod body, of the baffle ring extends outwards to form a convex edge, and two opposite first threaded holes are formed in the convex edge; a plurality of T-shaped opening grooves are evenly formed in the tail end of the innermost layer rod body, and second treaded holes are formed between every two adjacent T-shaped opening grooves; the grippers comprise linear sections and bent sections tangent with the linear sections, cylindrical rotating shafts are arranged at the free ends of the linear sections, the width of the linear sections is smaller than or equal to the opening width of the T-shaped opening grooves, the height of the rotating shafts is smaller than or equal to the width of inner grooves of the T-shaped opening grooves, and the diameter of the rotating shafts is smaller than or equal to the length of the inner grooves of the T-shaped opening grooves; cover plates are fixedly arranged at the end of the innermost-layer rod body, two plate lugs are further arranged on the cover plates, through holes corresponding to the first threaded holes in position are formed in the plate lugs, and two inner hexagon screws can penetrate through the through holes and are matched with the first threaded holes. The portable reflective film collector is simple in structure and convenient to carry.
