Environment-friendly epoxy resin closed high-pressure jet fuse

The invention relates to the technical field of jet fuses, in particular to an environment-friendly epoxy resin closed high-pressure jet fuse which comprises a column insulator body, connecting pieces are symmetrically and fixedly installed on the side wall of the column insulator body, two blocking covers are arranged on the right side of the column insulator body, and T-shaped grooves are formed in the two blocking covers. The two connecting pieces are slidably arranged in the two T-shaped grooves respectively, first screws are installed in the two blocking covers in a threaded mode, the surfaces of the two first screws are sleeved with internal thread rings in a threaded mode, and electrode connecting plates are arranged at the ends, away from each other, of the two blocking covers. The two electrode connecting plates and the two blocking covers are connected through the two first screws and the internal thread rings respectively, the sliding cylinder slides upwards in the annular groove, then the exhaust
