Device and system for taking out dynamic penetrometer

The utility model relates to a device and a system for taking out a dynamic penetrometer, which are characterized in that in the process of taking out the dynamic penetrometer, one end of a lifting piece is connected to a sounding rod; the other end of the lifting piece is connected to the main shaft; and then, the handle is pressed down to drive the main shaft to rotate on the support, so that the lifting piece is wound on the main shaft to lift the sounding rod. Due to the fact that stress of the sounding rod is transmitted by the lifting piece, tensile force transmitted to the sounding rod is always kept or approximately kept vertically upward, and structural deformation caused by transverse stress of the sounding rod is effectively avoided. And meanwhile, the resistance during pulling is reduced, and the structural stability of the sounding rod is greatly ensured, so that the dynamic sounding instrument is taken out stably. In addition, in the taking-out process, an operator only needs to fix the lifting
