The movable clamping block 3 can be far away from or close to the fixed clamping block 2 by sliding so as to adapt to PCBs with different sizes. Decide clamp splice 2 and move clamp splice 3 and be provided with draw-in groove 5, the extending direction of draw-in groove 5 and the slip direction mutually perpendicular of cutter 4, decide clamp splice 2 and move and be connected with holding screw 6 on the clamp splice 3, holding screw 6's one end extends in draw-in groove 5. The two sides of the PCB to be processed extend into the clamping grooves 5, and the PCB can be pressed and fixed by the set screws 6.

The bottom plate 1 is provided with a guide rail 17, and the guide rail 17 extends along the sliding direction of the movable clamping block. The guide rail 17 is arranged parallel to the slide groove 16. The cutter 4 is connected with the guide rail in a matching mode, the cutter 4 is connected between the fixed clamping block 2 and the movable clamping block 3 in a sliding mode, and the cutter 4 is arranged in parallel with the fixed clamping block 2. The PCB cutting machine is characterized in that scale marks are arranged on the bottom plate 1 along the sliding direction of the cutter 4, marks 10 are arranged on the cutter 4, and the scale marks can assist the specific distance of the cutter in moving so as to guarantee the accuracy of PCB cutting.
