Wearable electrocardio detector

The wearable electrocardio detector comprises a first connecting rod, a second connecting rod, a detection electrode, a conductive patch, a reference electrode and a signal processing circuit board, the detection electrode is arranged on the first connecting rod; the reference electrode is arranged on the second connecting rod; the signal processing circuit board is electrically connected with the detection electrode and the reference electrode respectively; the conductive patch is attached to the detection electrode and the reference electrode; and the first connecting rod is rotatably connected with the second connecting rod. According to the utility model, the first connecting rod and the second connecting rod are cooperatively used to form a detector structure which is simple in structure and convenient to carry, and the distance and angle between the detection electrode and the reference electrode can be changed by rotating the connecting rods; the reference electrode can conveniently fall at a proper de
