Detection device for electricity meter

The detection device comprises a detection main body, patch boards are symmetrically arranged at the two ends of the upper surface of the detection main body, wiring holes are formed in one sides of two sets of storage shells, storage assemblies are arranged in the two sets of storage shells, and a lower pressing plate is rotationally connected to the upper end of the rear side of the detection main body. According to the technical scheme of the utility model, the other group of fixed semi-ring plates is fixedly connected with one side of the winding rod, and one end, close to the connection patch board, of the detection line can be placed between the two groups of fixed semi-ring plates. The rotating rod can drive the adjusting nut to drive the fixed semi-ring plate below to move upwards to get close to the other group of fixed semi-ring plates through the driven screw rod, and during use, the detection line can be directly dragged, so that the detection line storage device is convenient to carry, can store
