Magnetic force measuring device

A magnetic force measuring device, comprising a measuring body and a pressure gage, wherein a center of the measuring body is provided with a longitudinal channel;

• a lifting system, an intermediate system, and a jacking block are arranged in the longitudinal channel from top to bottom;
• the pressure gage is associated with the intermediate system;
• a bottom surface of the measuring body and a bottom surface of the jacking block are flush to form a same contact surface in contact with a magnetic module;
• one of the measuring body and the jacking block is magnetically conductive, and the other is not magnetically conductive;
• when subjected to an external action force, the lifting system drives the intermediate system to move up or down in the longitudinal channel, so as to apply a force to the jacking block to lift the jacking block upward or push the jacking block to jack up the measuring body, and the pressure gage records a maximum stress value of the jacking block.
