Righting mechanism for tree transplanting

The utility model provides a righting mechanism for tree transplanting. The righting mechanism comprises two righting units which are symmetrically arranged. The two righting units are arranged on the two sides of a tree respectively and used for righting the two sides of the tree respectively, and the two righting units form a supporting ring used for supporting the tree. Each centralizing unit comprises a fixing base and a main supporting assembly. The fixing base is fixedly installed on the ground through the positioning device, the main supporting assembly is arranged on the fixing base, the main supporting assembly abuts against the outer side wall of a tree, and the main supporting assembly can expand outwards in the radial direction of the tree to adapt to tree growth. The two righting units are used for righting a tree, the fixing bases of the righting units are fixed to the ground, then the main supporting assemblies can abut against the outer side wall of the tree to support the tree, and in additio
