Pavement cold recycling machine for turning and milling old pavement

The invention relates to the technical field of pavement engineering, and discloses a pavement cold recycling machine for overturning and milling old pavements, the pavement cold recycling machine comprises a milling rotary drum, milling assemblies are uniformly distributed on the outer wall of the milling rotary drum, each milling assembly comprises a base, a tool apron and a tool, the bases are welded on the outer wall of the milling rotary drum, the tool aprons are fixedly sleeved in the bases, and the tool aprons are welded on the outer wall of the milling rotary drum. The cutter is movably sleeved in the cutter holder, and an elastic clamping sleeve is sleeved on the outer wall of the cutter. The paired direction adjusting assemblies are arranged in the tool apron, a strip block is made to move by introducing current into an electromagnetic coil and utilizing the repelling effect of an induced magnetic field on a fixed magnet, then the elastic clamping sleeve and the local position of the tool are pushed
