Positioning tool for explosion-proof plate welding and using method thereof

The invention relates to the technical field of explosion-proof plates, in particular to an explosion-proof plate welding positioning tool and a using method thereof.The explosion-proof plate welding positioning tool comprises a bottom frame, an adjusting device is arranged in the bottom frame, the adjusting device comprises an adjusting disc rotationally installed on the bottom frame, and an operating device used for driving the adjusting disc to rotate through self rotation is arranged on the bottom frame. According to the positioning tool designed by the invention, the hand wheel can be used for driving the adjusting disc to rotate by rotating the hand wheel, the adjusting disc can drive the rotating plate to rotate so as to determine whether the rotating plate is used for positioning the positioning clamping hook or not, and meanwhile, the adjusting disc can also control whether the clamping arm is fixed with the keel or not by rotating; and when the hand wheel rotates, the pressing block is driven to pre
