The invention relates to a carrying device of a throwing type fire-fighting grenade. The carrying device comprises, by weight, 100 parts of polyvinychlorid resin, 4 parts of dioctyl-phthalate, 2parts of MBS enhancement, 2.5 parts of stearic acid. A parathion method of the carrying device includes the following steps of adding the dioctyl-phthalate to the polyvinychlorid resin at the temperature of 38EDG C-42DEG C, evenly stirring and enabling the dioctyl-phthalate and the polyvinychlorid resin to coexist for 10 minutes, adding the MBS enhancement to mixture of the polyvinychlorid resin and the dioctyl-phthalate, evenly stirring and enabling the MBS enhancement and the mixture of the polyvinychlorid resin and the dioctyl-phthalate to coexist for 10 minutes, adding the stearic acid to mixture of the MBS enhancement, the polyvinychlorid resin and the dioctyl-phthalate, evenly stirring the stearic acid and the mixture of the MBS enhancement, the polyvinychlorid resin and the dioctyl-phthalate to coexist for 10 minutes, putting mixture of the MBS enhancement, the polyvinychlorid resin, the dioctyl-phthalate and the stearic acid in an extruder, heating the mixture to reach from 160 DEG C to 180 DEG C, plastify the mixture for one hour, and forming the carrying device in a granule-cutting mode. The carrying device of the throwing type fire-fighting grenade has the advantages of being abundant in number, favorable for taking of the throwing type fire-fighting grenade, easy to use and the like.
