Automobile MOS tube with anti-avalanche effect

The utility model discloses an automobile MOS tube with an anti-avalanche effect, and relates to the technical field of MOS tubes, the automobile MOS tube comprises a tube body, a first driving lever and radiating fins, one side of the tube body is fixedly connected with a pin, the bottom of the tube body is connected with a connecting plate, and one side of the first driving lever is movably connected with the tube body through a rotating shaft. According to the automobile MOS transistor with the anti-avalanche effect, a positioning block at the bottom of a transistor body is in butt joint with a mounting hole in a connecting plate, and when inclined surfaces of a first clamping block and a second clamping block on two sides of the positioning block are in contact with the connecting plate, the first clamping block and the second clamping block can move and extrude a first spring on one side, so that the first spring shrinks; and when the first clamping block and the second clamping block are in contact with
