Embedded type controllable unloader
The invention discloses an embedded type controllable unloader. The embedded type controllable unloader comprises a bottom plate, wherein a hollow pipe is arranged in the center of the bottom plate; a screw rod is inserted into the hollow pipe and sleeved with a thrust bearing and a first nut; the thrust bearing is propped against the hollow pipe; the first nut spins the thrust bearing; a top plate is arranged at the upper end of the screw rod. The embedded type controllable unloader has the advantages as follows: 1), the first nut is pulled by a torque wrench, and required jacking force can be obtained through torque force by inquiring a relation table of torque force and the jacking force; 2), once the required jacking force is obtained, the first nut is locked after the torque wrench is removed, and jacking force attenuation can be prevented; 3), the wall blocking is not influenced when the unloader is put in the wall.
