Zusammenfassung:	The utility model relates to an enlarging and contracting machine for shoe patterns, which is provided with a working bench, a dash receiver, a vertical large car, an input car, an output car, etc. The middle part of a rod is hinged on the vertical large car. Both ends of the rod respectively pass through another two rods and are hinged with the output car and the input car, and two lateral input and output similar triangles are formed. The middle part of another rod is hinged on a machine base. Both ends of the rod respectively pass through other two rods and are connected with the vertical large car and the dash receiver, and two longitudinal input and output similar triangles are formed. Besides, longitudinal and lateral two mechanisms are respectively provided with a movable hinge. The utility model has the advantages of simple structure, high precision and low cost. The enlarging and contracting error is less than (+/-) 0.2 mm.
