Infinite Gaussian normally-working SMR chip

The utility model belongs to the field of SMR chips, and particularly relates to an SMR chip with infinite Gaussian normal operation, which comprises a chip main body and a circuit board. The circuit board is provided with a fixing mechanism, the fixing mechanism comprises a long plate, the long plate is fixedly connected to the front side and the rear side of the chip body, a protruding block is fixedly connected to the side, away from the chip body, of the long plate, clamping grooves are formed in the left side and the right side of the protruding block, and trapezoidal clamping blocks are inserted into the clamping grooves. A spring is fixedly connected to one side of the trapezoidal clamping block, the side, away from the trapezoidal clamping block, of the spring is fixedly connected to the inner wall of a moving groove, and the moving groove is formed in the fixing plate; through the structural design of the fixing mechanism, the chip main body is additionally fixed, so that the fixing effect of the chi
