Abstract
The utility model relates to a sickle with an alarm function. The sickle comprises a blade, a sickle handle and a switch, a battery and a control circuit which are arranged on the outer surface of the sickle handle, wherein the blade is connected with one end of the sickle handle; the control circuit is arranged on the lower side of the connecting position of the blade and the sickle handle; the switch, the battery and the control circuit are connected by a wire; the control circuit consists of an infrared sensor, a control unit and a sound production unit; the infrared sensor is connected with the input end of the control unit by a transmission line; and the output end of the control unit is connected with the sound production unit. The sickle is simple in structure and reasonable in design; when the sickle is used by people, the infrared sensor judges whether fingers of the people cross the connecting position of the blade and the sickle handle or not, and once the fingers of the people cross the connecting position, the possibility of cutting the fingers occurs; and a signal is sent, and after passing through the control unit, the signal is outputted to the sound production unit, so that the sound production unit sends an acoustical signal to remind users of keeping hands away from the blade of the sickle, and the safety of the users is ensured.
