The invention discloses a device for detecting cigarette head dropping direction by utilizing a rotating mode. The device is characterized by comprising a base, a motor, a cigarette clamping mechanism driven by the motor to rotate and a safe protective cap, wherein the cigarette clamping mechanism is composed of a rotating arm and two cigarette clampers fixed on the two ends of the rotating arm, and the rotating arm is fixed on a motor shaft through a rotating arm support and a locking rotary knob; and the two ends of the rotating arm are provided with strip-shaped grooves, and the cigarette clampers are arranged in the strip-shaped grooves through a connecting piece and the positions of the cigarette clampers in the grooves ca be adjusted. The device provided by the invention tests a head dropping phenomenon of a cigarette combustion cone through a rotating mode, so that a novel detecting method by virtue of the combustion cone is created; statistical data for head dropping can be obtained through multiple times of detection, so that performance indexes for head dropping direction when a cigarette combusts are obtained. The device provided by the invention has the advantages that the rotational time and revolutions are controllable, and different detecting intensities can be applied aiming at different samples, so that the application range is wide; and the detection method is simple and convenient, the time is short, and the detection cost is low.
