The invention relates to a scissors fork lifting type auxiliary supporting mechanism capable of being locked at a random position. The scissors fork lifting type auxiliary supporting mechanism comprises a bracket and a top plate below the bracket. The bracket is fixedly connected with the top plate through two disc springs, a base plate is positioned below the top plate, a screw is horizontally arranged in the length direction of the base plate, a hand wheel is installed on the outer side of one end of the screw, and the middle of the screw is in threaded connection with a first sliding block and a second sliding block which are arranged at intervals. When the hand wheel is rotated, the first sliding block and the second sliding block can perform opposite-direction movements in the axial direction of the screw, four groups of linkage mechanisms are further arranged between the top plate and the base plate, the upper ends of the linkage mechanisms are hinged to the top plate, the lower ends of the linkage mechanisms are hinged to the first sliding block and the second sliding block respectively, and the first sliding block and the second sliding block can drive each group of linkage mechanisms to perform lifting movements when moving. The supporting mechanism can reliably support a product and have a large displacement lifting function, can perform fine adjustment of the vertical position, can be reliably locked at the random position, is small in vertical dimension and meets the installing space requirements.
