The invention discloses a high-sensitivity no-driver weight measuring type resonator detection device. The high-sensitivity no-driver weight measuring type resonator detection device comprises a horizontal table and a movable plate, wherein the horizontal table is provided with a through groove; the side wall of the through groove is provided with a limiting base which is provided with a limitinggroove and a compression spring; a first electromagnet is arranged below the limiting base; a second electromagnet is embedded in the side wall of the side, away from the limiting base, of the throughgroove; one side of the movable plate is provided with a rotating shaft fixedly assembled with the movable plate; a locking block made from a ferromagnetism material is arranged on the side, away from the rotating shaft, of the movable plate; the movable plate is located in the through groove, and the lower plate face of the movable plate is fixed to the compression spring; when a compression value of the compression spring is smaller than a preset value of the compression spring, the first electromagnet is powered off, and the second electromagnetic is powered on; and when the compression value of the compression spring reaches the preset value, the second electromagnet is powered off, and the first electromagnetic is powered on. The high-sensitivity no-driver weight measuring type resonator detection device is sensitive in responding, high in detection efficiency, and little in energy consumption, and no drivers are needed by the whole device.
