The invention provides a rapid ammeter detection device, belongs to the detection technology field and solves a problem of low efficiency of manual test in the prior art. The detection device comprises a conveyor belt, wherein probes used for being in contact electrical connection with wiring columns of ammeters are arranged along the direction of the conveyor belt, the probes are in units of sets, the quantity of the probes of each set is identical to the quantity of the wiring columns, intervals of the probes are identical to intervals of the wiring columns, the probes are arranged on a fixing block, the fixing block is arranged on a first gear capable of rotating freely, the conveyor belt is provided with a sliding groove perpendicular to the conveying direction of the conveyor belt, a sliding rod is arranged in the sliding groove in a sliding mode, a spring used for pushing the sliding rod out of the sliding groove is arranged between the bottom end of the sliding rod and the sliding groove, the top end of the sliding rod is fixed with a second gear, and a first gear can be engaged with the second gear for driving. The detection device is advantaged in that the ammeter wiring column probes arranged at two sides of the ammeter conveyor belt can conveniently detect the ammeters when the ammeters are conveyed through the conveyor belt.
