The invention discloses a conveying belt module disassembling and assembling clamp. The clamp comprises a bending piece, a tooth inserting piece and a pulling plate, wherein the bending piece comprises a bottom plate and a positioning plate extending upwards from the edge of the bottom plate, and the positioning plate is perpendicular to the bottom plate; the tooth inserting piece is assembled onthe positioning plate, the lower surface of the tooth inserting piece is provided with a plurality of vertical teeth in a downward extending mode, the thickness of the vertical teeth is smaller than or equal to the distance between balls and modules so that the vertical teeth can be inserted into the gaps between the balls and the modules; and one end of the pulling plate is vertically fixed on the positioning plate, and longitudinal pulling force is provided for the tooth inserting piece by the pulling plate after the pulling plate is subjected to external force. According to the clamp, pulling force between the adjacent modules and a penetrating shaft can be easily relieved, and the replacement efficiency of the modules is improved.
