Automatic timing water bath oscillator internally coated with corrosion-resistant layer

The utility model discloses an automatic timing water bath oscillator internally coated with a corrosion-resistant layer, which comprises an oscillator body, four vibrating arms arranged on two sides of the oscillator body, a protective cover and an oscillation box, and support plates matched with the vibrating arms are symmetrically and fixedly mounted at the top ends of two opposite sides of the oscillation box. The inserting holes formed in the supporting plate are sleeved with the limiting rings fixedly installed at the top ends of the limiting columns, at the moment, the multiple movable plates are pushed towards the interior of the rectangular groove through the shifting rings, the limiting columns can slide into the sliding grooves formed in the supporting plate, the supporting plate can be limited and fixed through the limiting columns and the limiting rings, and therefore the supporting plate can be conveniently fixed. When the vibration box is disassembled, the vibration box can be taken out as long
