Abstract:
1. A hot air generator device comprising an injection device capable of producing a flow of combustible gas mixture at high velocity, said injection device including tubing comprising a convergent back section, a divergent front section, an injection nozzle mounted in the convergent section and connected to a source of pressurized gas, an opening for letting through air located in an annular area comprised between said nozzle and said back section, and a first handle mounted on said tubing and a burner head, in which said flow is injected via a tubular extender connecting said injection device to said head, said device further comprising an extractable and/or retractable holding device, mounted on the injection device, said holding device being intended to be supported on the forearm of the operator when the latter holds the device with the first handle with which the injection device is equipped, the holding device being formed by a rod having a rectilinear portion, extending on one side with a bent portion in a plane perpendicular to the axis of the rectilinear portion and wherein the rectilinear portion engages into a sliding bearing provided on the injection device and with an axis parallel to the latter, said sliding bearing being equipped with a device for axially and rotatably blocking the rod.
