The invention provides a low small shear type car lifter with an extensible approach bridge and a using method of the low small shear type car lifter. The low small shear type car lifter comprises two bases, two safety locks, two solenoid valves, an external shearing arm, an internal shearing arm, two supporting platforms, four creepers, two power-assisted arms, two power-assisted arm pulling plates and a control tank, wherein the two safety locks are arranged on the bases; the two solenoid valves are arranged on the bases; the external shearing arm comprises a straight tube and two supporting parts which are frame bodies; the internal shearing arm comprises a U-shaped supporting frame formed by a connecting tube and a supporting rod, and two straight rods; the supporting rod and the straight rods of the internal shearing arm are inserted into the supporting parts of the external shearing arm; slide paths are arranged on the bottom surfaces of the two supporting platforms, can be connected with the supporting parts of the external shearing arm in a sliding mode, and can be connected with the end parts of the supporting rod and the straight rods of the internal shearing arm in the sliding mode; two connecting lug rings are arranged at the two ends of each supporting platform in a width direction; the four creepers are connected with the connecting lug ring shafts by connecting shafts; and the two ends of each creeper are downwards extended in a width direction to form lap joint plates. The creepers of the lifter can rotate around the supporting platforms, so that the effective lengths of the supporting platforms are increased, and therefore, the low small shear type car lifter is suitable for cars with different lengths, the applicable range is expanded, and the market prospect is expanded.
