Working principle: the knife body 1 is internally provided with a hollow chamber 11, the interior of the hollow chamber 11 is provided with a metal foam material or a honeycomb metal or reinforcing rib structure, the inside of the honeycomb metal or the reinforcing rib structure is mutually communicated so as to facilitate the communication of gas, liquid and powder in the interior, the purpose of portability can be achieved, the hollow chamber of the metal foam material or the honeycomb metal or the reinforcing rib structure can effectively prevent the problem of stress deformation of the knife body, liquid such as ignition oil, water or the like or powder such as insect repellent powder, water purification powder or the like or cold medicine cough medicine, medicines such as anti-inflammatory medicine or the like or medicines such as cyanide and the like are hermetically stored in the hollow chamber 11 by using a leakage prevention plug made of rubber, paraffin or plastic film, and when the multifunctional mechanism 12 is a flame-initiating mechanism 121, a magnesium rod 1214 is arranged so as to facilitate field flame initiation; the push-pull inflating rod 442 injects gas into the hollow chamber 11 to increase the internal pressure of the hollow chamber 11, when danger is encountered, the threaded sealing button 142 is pressed, the therapeutic agent for treating diseases or the gas-liquid for attack defense stored in the hollow chamber 11 is ejected from the valve core 143 through the ejection hole channel 141 by utilizing the pressure, the ignition device 15 is arranged on the ejection hole, the percussion mechanism 151 is pressed to generate electric sparks, the attack-defense gas-liquid can be instantaneously ignited when being ejected, the attack force is increased, the defending effect is improved, and the sealing screw 145 is unscrewed to connect the inflating pipe push-pull inflating rod 442 to inflate objects needing to be inflated, such as inflatable boats, tire balls and the like.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The invention is not to be limited by the specific embodiments disclosed herein, and other embodiments are within the scope of the invention as defined by the claims of the present application.
