Magnetic detection mechanism used for money

The invention discloses a magnetic detection mechanism used for money. The objective of the invention is to solve problems that it is hard to grasp money passing gaps, money can be easily clamped, money is easily damaged, the magnetic press wheel is quickly worn and the service lifetime of the press wheel is short of the current money magnetic detection mechanism. The mechanism comprises supports and a rotary core shaft. Two ends of the rotary core shaft are rotatably installed on the supports. One end of the rotary core shaft is connected with a transmission mechanism. A magnetic sensor is arranged under the rotary core shaft on the support. Multiple magnetic press wheels are installed on the rotary core shaft. Relief holes are arranged in connection positions of the supports and the rotary core shaft. Two ends of the rotary core shaft are capable of up-down swinging to be installed in the relief holes. Two ends of the rotary core shaft stretch out of the supports. End pars of the rotary core shaft are conne
