Tool and method for pressing and shortening heavy telescopic rod of protective cover

The invention discloses a tool and method for pressing and shortening a heavy telescopic rod of a protective cover, solves the problem that in the prior art, the telescopic rod still has supporting elasticity in the dismounting process, and has the beneficial effects that the length of the telescopic rod can be effectively kept, and the telescopic maintenance efficiency is improved. According to the specific scheme, the tool for pressing and shortening the heavy telescopic rod of the protective cover comprises a main base plate and a clamping piece, the main base plate and the clamping piece clamp an upper connecting column of the telescopic rod, the upper connecting column is connected with an upper mounting block connected with the protective cover, and the main base plate movably supports a torsion gear assembly; the torsion gear assembly can rotate relative to the main base plate under the action of external force and is meshed with the screw hole gear assembly through the transition gear assembly, the sc
