The nose clip as claimed in claim 1, wherein the distance between the two second respectively located on the two clipping arms is less than the distance between the two first ends respectively located on the two clipping arms so as to comfortably secure the nose clip onto the user's wings of the nose. 3. The nose clip as claimed in claim 1, wherein a pair of opposed rims are formed on each flexible pad with a locating groove that can be into by a rim formed along each sides of the assembling groove whereby in the assembling process, the flexible pad can slide onto the assembling groove of the clipping parts to be positioned effectively with cooperation between the rim of the assembling groove and the locating groove of the flexible pad, by actuating a pushing force on the flexible pad along the assembling groove on the clipping arms to reach the clipping part. 4. The nose clip as claimed in claim 3, wherein after the flexible pads are forced to reach the assembling groove of the clipping parts, on each of the positioning groove opposite to the assembling groove of the clipping arms is a stop salient designed to prevent the flexible pad from displacement. 5. The nose clip as claimed in claim 3, wherein the flexible pads are made of rubber material, and one side thereof in contact with the user's nose is slightly protruded out of the assembly groove in the clipping part to form an arched face. 6. A nose clip that is worn on a user's nose to prevent water from flowing into the user's nasal cavity, the said nose clip comprising: a main body which has two clipping arms and a clipping part at one end of each clipping arm, characterized in that: there is at least an assembling groove extended along said clipping arms to reach the clipping parts, and a pair of flexible pads each with opposite rims and a locating groove are respectively installed onto and then securely slide on along the assembling groove to reach the clipping part by means that the opposite rims of each pad are protruded out of the said assembling groove in different directions and the corresponding locating groove accommodates a rim formed with each side of the assembling groove to prevent the rim of assembling groove from displacing out where is between the opposite rims of the each pad to provide a comfortable clipping effect. 7. The nose clip as claimed in claim 6, wherein after the flexible pads are forced to reach the assembling groove of the clipping parts, on the positioning groove opposite to the assembling groove of the clipping arms are a stop salient to prevent the flexible pads from dislocating. 8. The nose clip as claimed in claim 7, wherein the said flexible pads are made of rubber material, one side of the flexible pad in contact with the nose being slightly protruded to become an arched face. on guidance appliance hanged beneath a top of said body prop, wherein said suspension guidance appliance has a distance from said outlet for extracting rising exhaust along said airstream baffles; an air-rotating device comprising two auxiliary bellows provided at said downside of said body prop, wherein each of said auxiliary bellows comprises an air inlet fan at a rear end thereof to inhale outer air into said two auxiliary bellows and has a plurality of air pipes thereon to produce raising air current for pushing exhaust forward to said suspension guidance appliance, so that said exhaust is gathered via said auxiliary bellows along said airstream baffles to an upper part and discharged by said suspension guidance appliance through said outlet; and a control panel provided at a side of one of said auxiliary bellows. 2. A jet airstream guidance device, as recited in claim 1, further comprising one or more suspension guidance appliances provided alongside. 3. A jet airstream guidance device, as recited in claim 1, wherein said outlet provided on said upside of said body prop is communicated with said suspension guidance appliance. 4. A jet airstream guidance device, as recited in claim 1, wherein each of said auxiliary bellows has a shape extended gradually from front to back for concentrating said exhaust. 5. A jet airstream guidance device, as recited in claim 1, further comprises a filter net provided at an underside of said suspension guidance appliance. y, No. 10, Oct. 1960, pp. 841-844.
