Portable chest lead electrocardiogram collector

The invention provides a portable chest lead electrocardiogram collector, and relates to the technical field of medical instruments. The collector comprises a bracket made according to the shape of the chest of a human body and an electrode fixed on the bracket according to the chest lead position, and magic tapes connected with the arms of the human body are symmetrically arranged at the two endsof the bracket. Each electrode is slidably provided with a mounting base fixedly provided with the electrode, a compressed spring is arranged right opposite to the mounting base, the compressed springs are separated through a partition plate, whether the partition plate is opened or not is achieved through rotation of a center gear, and the electrode slice can abut against the skin of the human body by moving the partition plate away from the springs and popping up the springs; the electrode slice in each electrode is connected to the electrocardiosignal collecting unit through a wire, and the electrocardiosignal col
