Electronic circuit board etching device

The invention relates to an etching device, in particular to an electronic circuit board etching device. The invention provides the electronic circuit board etching device which can stir the acid solution and accelerate the reaction speed of the circuit board and the acid solution. The electronic circuit board etching device comprises a liquid storage tank, supporting legs, guide rails and a sliding plate, the supporting legs are fixedly arranged on the left side and the right side of the bottom of the liquid storage tank in a front-back symmetry mode, the guide rails are fixedly arranged on the left portion and the right portion of the liquid storage tank, and the sliding plate is arranged between the two guide rails in a sliding mode. Under the action of cooperation of a rack and a gear, a stirring rod can rotate to stir an acid solution in a liquid storage box, so that the reaction speed of the acid solution and a circuit board is increased, the circuit board moves upwards to make contact with a sponge rol
