The invention discloses an integral crimping tool for a PCB stamping part, which comprises a base, a press buckle, a positioning column, a movable limit upper cover and a steel sheet, wherein the press buckle and the positioning column are respectively arranged at the upper end of the base, the movable limit upper cover is arranged on one side of the upper end of the base, and the steel strip is detachably mounted on the bottom of the movable upper limit cover. Through the above, the integral crimping tool for the PCB stamping part of the present invention is used for brushing tin on connectors on the PCB board, and can sufficiently avoid components on the edge when brushing tin, so that the tension of the steel sheet subjected to tin brushing is ensured, the tin applying content of component pins of the connectors on the PCB board is ensured to be sufficient, no soldering flux is left, the product yield and the product efficiency are improved, the cost is lowered, and the batch replacement of intensive pin components is achieved.
