The invention discloses a sectional type thrust lifting mechanism which comprises an upper supporting beam, a lower supporting beam, a left supporting arm, a right supporting arm, a left support, a right support, a pre-thrust air cylinder and a main thrust air cylinder. The two ends of the left supporting arm and the two ends of the right supporting arm are hinged to the upper supporting beam and the lower supporting beam respectively. A parallelogram connection rod mechanism is formed by the upper supporting beam, the lower supporting beam, the left supporting arm and the right supporting arm. The left supporting arm and the right supporting arm are hinged to the left support and the right support respectively. The pre-thrust air cylinder is vertically arranged below the upper supporting beam to be used for thrusting the upper supporting beam upwards to reach the preset first height. The main thrust air cylinder is transversely arranged below the upper supporting beam to act on the parallelogram connection rod mechanism so as to drive the left supporting arm and the right supporting arm to thrust the upper supporting beam upwards to reach the preset second height. Compared with the prior art, the sectional type thrust lifting mechanism uses two groups of air cylinders to thrust the upper supporting beam upwards to reach two segments of heights and has the advantages of being compact in structure, small in shape, simple in structure and capable of meeting the requirement for the small size of the lifting mechanism of industrial production.
