As preferably, cutting torch described in the utility model also comprises valve rod, and described valve rod comprises valve rod main body and end socket, and valve rod main body and end socket are for being fixedly connected with, and valve rod one end connects handwheel, and the other end is connected with mid-section body by end socket, the formation air circuit breaker.
As preferably, between described mixture pipe and the mid-section body injecting tube is set, described injecting tube outer setting overcoat, injecting tube one end is connected with mixture pipe silver soldering, and the other end is fixedly connected with mid-section body by nut.
As preferably, fireproof tempering device described in the utility model and mixture pipe are connected with cutting head joint and are connected to silver soldering and are connected.
As preferably, spiral bar described in the utility model is that torsional mode is wiped rope shape spiral bar.
As preferably, spiral bar described in the utility model is more than one.
As preferably, the parameter of spiral bar described in the utility model is: helical pitch is 4～12mm, and external diameter is 3～8mm, and thickness is 0.5～1.5mm.
As preferably, end socket described in the utility model is the stainless steel end socket.
The beneficial effects of the utility model are, fireproof tempering device is arranged between cutting head joint and the mixture pipe, prevent that effectively tempering from occuring, simultaneously, spiral bar makes the preheat flame of cutting torch more stable, concentrated, improve preheating speed and cutting speed, used safety, the back draft accident of effectively avoiding a variety of causes to cause.
