[0006] The technical solution of the utility model is: a flame knife for performance with rapid powder filling, comprising a knife tip, a blade, a grip, a feeding assembly, an ignition assembly, and a cotton rope; the blade tip is fixedly connected to the blade body at the rear side, a grip with a hollow structure is sleeved on the outer side of the bottom end of the blade body, a feeding assembly for transporting fuel is installed in the grip, a notch is opened on the right side of the grip, an ignition assembly is installed on the inner side of the grip, and a cotton rope is arranged on the front side of the feeding assembly and is wound around the blade body and the knife tip.

[0007] Preferably, by replacing the oil fuel with powdered fuel, the powdered fuel is transported to the cotton rope wrapped around the blade and the tip of the blade through the loading assembly, and the ignition assembly uses electric sparks to ignite the powdered fuel and the cotton rope, thereby achieving the effect of wrapping the blade with flames, thereby improving the aesthetics of the finished film.

[0008] Preferably, the feeding assembly includes a powder bottle and a copper tube; a powder bottle is arranged in the handle, and a powder fusion as fuel is placed in the powder bottle. A copper tube is inserted into the front side of the powder bottle, which is close to the right side of the blade and 8-15 cm away from the tip of the blade. The powder in the powder bottle can be selected according to the desired effect. Ordinary flames use flour and cornstarch, etc., and flame color changing effect can be achieved by adding flame color changing powder to the powder bottle. When an active effect is required, fruit charcoal powder can be added to the powder bottle, and the copper tube transfers the powder in the powder bottle to the cotton rope wrapped around the performance knife.

[0009] Preferably, the feeding assembly further includes a high-pressure gas tank and an electronic valve; the high-pressure gas tank is arranged in the handle, a hose is connected between the high-pressure gas tank and the powder bottle, an electronic valve with a built-in battery is installed on the hose, and the electronic valve is opened to provide the hose with flow capacity, so that the gas in the high-pressure gas tank can flow into the powder bottle through the hose, blowing the powder in the powder bottle into the copper tube.

[0010] Preferably, the loading assembly also includes a movable groove and a switch; a movable groove is opened on the left side of the handle, and the switch of the electronic valve is inserted into the movable groove. The electronic valve is switched on or off by the switch to achieve the effect of opening or closing the high-pressure gas cylinder.
