The clamping tool for SMT patch processing includes: a base frame, the top surface of which is provided with a threaded through hole; and a clamping assembly, which includes: a processing frame, a threaded rod, four guide rods and two clamping parts. The processing frame is arranged above the base frame, and the threaded rod is rotatably connected to the bottom surface of the processing frame. The clamping tool for SMT patch processing is fixed and installed through the base frame and the bottom support block, so that it is installed in the predetermined position. The threaded rod pushes the processing frame to move. When facing different PCB boards, slots can be opened on the top surface of the processing frame according to different situations to make them fit together to enhance the fixing effect. The cylinder clamping plate moves downward to position and clamp both sides of the PCB board. The processing frame can be adjusted to avoid errors caused by operation, reduce repair and maintenance time, and facilitate production use.

[0003] However, when the SMT patch processing clamping tool in the prior art is used, the clamping work is installed in a predetermined position only by cooperating with the base frame and the support block.
