The invention discloses a pull rod type lifting mechanism. The bottom end of a lifting oil cylinder of the pull rod type lifting mechanism is connected with a rear vehicle body, and the top end of a piston rod is connected with a front vehicle body. Fork legs are symmetrically arranged at the front end of the front vehicle body. U-shaped blocks are symmetrically arranged at the bottom of the rear vehicle body. Front swing arm plates and rear swing arm plates are symmetrically arranged on a rocking bar assembly. A first through hole is formed in one side of each rear swing arm plate. Second through holes and third through holes are formed in the other sides of the rear swing arm plates and the other sides of the front swing arm plates. The first through holes are hinged to the U-shaped blocks, and the second through holes are hinged to the fork legs. Front wheels are hinged to the front ends of front wheel supports, and the rear ends of the front wheel supports are hinged to the front ends of the fork legs. One end of a pull rod assembly is hinged to the rear portion of the corresponding front wheel support, and the other ends of the pull rod assemblies are hinged to the third through holes. Through work of the lifting oil cylinder, the front vehicle body is lifted, the pull rod assemblies are indirectly made to pull the front wheel supports to rotate, the front wheels are made to be grounded, and a supporting function is achieved.
