High-precision cutting tool for civil air defense door production and machining

The invention discloses a high-precision cutting tool for civil air defense door production and machining. Limiting plates are installed on the edges of the top ends of the inner sides of a cutting table. Clamping grooves are formed between the limiting plates and a cutting carrier plate; connecting screw rods are mounted on the two sides of the interiors of the limiting plates; the bottom ends ofthe connecting screw rods are connected with fixed chucks at the positions inside the clamping grooves; fixing rotary knobs are connected to the positions, corresponding to the fixing chucks, of thetop ends of the connecting screw rods; according to the invention, through the limiting plates, the clamping grooves, the connecting screw rods, the fixing chucks and the fixing rotary knobs, a civildefense door plate to be cut and the cutting table can be rapidly clamped, so that the civil air defense door plate does not loosen in the actual cutting process, the cutting precision of the civil air defense door plate is gua
