A placement groove is opened inside the workbench. A middle groove in the front-back direction is opened in the middle of the placement groove. A clamping structure is arranged in the middle groove to adaptively clamp the circuit board placed in the placement groove, and at the same time, the circuit board can be manually pushed along the placement groove. The clamping structure does not affect the left-right movement of the circuit board. An outlet is opened on the right side of the workbench, which is communicated with the placement groove. The cut circuit board is transferred to the right side from the outlet and manually taken out. The lead screw is rotatably installed in the front-back direction on the right side of the placement groove, and the guide shaft is fixedly installed. The lead screw is driven by a driving motor, and this driving motor is powered by an external power supply.
