The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Referring to Fig. 1～Fig. 5, cutting torch connector of the present utility model, it comprises: rotating main body 10 and rotation core 20.
Described rotating main body 10 has a combustible gas interface 12, an oxygen interface 11 and jatharapanvartanasana inner chamber 13.
Described rotation core 20 rotatably places among the described jatharapanvartanasana inner chamber 13 and has flammable air cavity 22 and oxygen chamber 21.
Between described rotating main body 10 and rotation core 20, be provided with isolated each other combustible gas passage 40 and oxygen channel 30, described combustible gas interface 12 and flammable air cavity 22 are communicated with described combustible gas passage 40 respectively, and described oxygen interface 11 and oxygen chamber 21 are communicated with described oxygen channel 30 respectively.
