Adjustable net rack jacking support

The utility model belongs to the technical field of net rack jacking construction, and particularly relates to an adjustable net rack jacking support which comprises a supporting plate and further comprises a ball support, the ball support comprises at least one lateral limiting support set, and each lateral limiting support set comprises two lateral limiting supports which are oppositely arranged; the two lateral limiting supports are installed on the supporting plate in a relatively movable mode. Through relative sliding of the lateral limiting supports in the lateral limiting support sets, the supportable size of the ball support can be adjusted according to the size of a net rack ball needing to be supported, angle limitation existing between a jacked net rack and a jacking structure is reduced, the risk of deformation of the net rack in the jacking process can be reduced through the jacking supports with the proper size, and the jacking stability of the net rack is improved. And meanwhile, the efficiency
