Claim:
A portable membrane packing apparatus comprising: a holding-and-drawing rod having a lengthwise holding rod, said lengthwise holding rod having its opposite ends respectively bent and formed with a transverse combining rod; two reel connectors respectively assembled at intermediate portions of said two combining rods, one of said two reel connectors able to be elastically moved inward at a preset distance, a membrane reel able to be respectively and movably assembled with said two reel connectors after said elastically contractible reel connector is moved inward, said membrane reel rotated to supply membrane for packing; a first roller unit having a first roller, said first roller having its opposite ends respectively fixed with a driven gear, said two driven gears respectively and axially assembled on the inner wall of the end of said combining rod; a second roller unit positioned beside said first roller unit and having a second roller, said second roller having its opposite ends respectively fixed with an actuating gear; a swaying plate having a preset portion of one side pivotally assembled between the first of said driven gears of said first roller unit and said combining rod by the same shaft of said first roller, said swaying plate having a preset portion of the opposite side pivotally assembled on the outer side of the first of said actuating gear of said second roller by the same shaft of said second roller, said actuating gears of said second roller respectively meshing with said driven gears of said first roller, said swaying plate having another side bored with a curved guiding groove at a preset portion, said reel connector having its shaft bolt inserted in said curved guiding groove of said swaying plate, said swaying plate restricted to move biasly by said curved guiding groove for said shaft bolt to move along therein; and a connecting plate having a preset portion of one side pivotally assembled between the second of said driven gears of said first roller and said combining rod by the same shaft of said first roller, said connecting plate having a preset portion of the opposite sides pivotally assembled at the outer side of the second of said actuating gear of said second roller by the same shaft of second roller, said driven gears of said first roller respectively meshing with said actuating gears of said second roller, said membrane moved out of said membrane reel to pass through between said first and said second roller, said membrane then compressed on said second roller to be drawn outward for carrying out packing around a loading plank and the articles piled thereon.
