Mechanism for stably improving power supply of rectifier of crude foil engine

A mechanism for stably improving power supply of a crude foil engine rectifier relates to the field of industrial production, and comprises a movable plug-in and a static plug-in, the bottom of the movable plug-in is provided with three plug-in grooves with downward openings, the three plug-in grooves are uniformly distributed in a bilateral symmetry manner, and each plug-in groove is internally provided with two groups of plug-in clamping blocks; three first plug connectors are fixedly arranged on the top of the movable plug connector in a left-right symmetry mode, a first plug bolt is installed in each first plug connector, and after the static plug connector is inserted into the movable plug connector, the plug board is inserted into the limiting groove, so that the static plug connector is inserted into the movable plug connector, and the static plug connector is inserted into the limiting groove. The limiting insertion rod is inserted into the limiting sliding hole through the through hole in the limitin
