The invention provides an anti-pinch device for a door suit. A base plate is arranged in a mounting groove, a compression spring is arranged between the base plate and the bottom of the mounting groove, and a baffle plate is arranged above the base plate, penetrates through an opening formed in a floor and comprises an inclined surface facing the door suit and a blocking surface turning the back to the door suit. The baffle plate is fixed to the base plate, the base plate is arranged in the mounting groove, and the base plate can perform telescopic movement in the mounting groove under the effect of the compression spring. Due to the fact that the baffle plate comprises the inclined surface facing the door suit and the blocking surface turning the back to the door suit, when a door leaf is opened, the bottom of the door leaf extrudes the inclined surface and downwards presses the baffle plate into the mounting groove, and accordingly the door leaf can be smoothly opened. When the door leaf is required to be closed, the base plate rebounds under the effect of the compression spring and enables the baffle plate to re-extend out of the floor. Due to the fact that the back surface of the baffle plate is the blocking surface, when the door leaf is closed, the door leaf hits against the blocking surface, and accordingly the door leaf is not directly closed. Therefore, the safety accident of hand pinching does not occur.
