Cutter adjusting device of small-breadth battery diaphragm splitting machine and splitting machine

The invention aims to disclose a small-breadth battery diaphragm splitting machine cutter adjusting device and a splitting machine. The small-breadth battery diaphragm splitting machine cutter adjusting device comprises an upper cutter shaft rotationally arranged between a first swing block and a second swing block and a supporting rod fixedly arranged between the first swing block and the second swing block. The supporting rod penetrates through the first swing block, and an angle adjusting assembly and a translation assembly are arranged at the end of the supporting rod. The angle adjusting assembly comprises a worm and a turbine, the turbine drives the supporting rod to rotate, the supporting rod drives the first swing block and the second swing block to swing, and therefore the upper cutter shaft can swing. The translation assembly comprises a handle and a screw rod, the handle is swung to drive the supporting rod to translate, and the technical effects are that the position of the cutter shaft of the upp
