Lance for heating hand tool without temperature rises along the nozzle

Lance for a heating tool, comprising

• a nozzle (2) connected at a first of ends (21) thereof to a handle of the hand tool, the nozzle (2) comprising a combustible gas inlet (23) and a conductive wire (24) forming an electrode for the priming of a spark;
• a grid (25) arranged at a second end (22) of the nozzle (2) for holding a flame that ignites at the priming of the spark in a combustible gas flow, the conductive wire (24) extending through said grid (25) and outside the nozzle (2);
• a cup (4) for evacuating hot burned gas positioned at the second end (22), the evacuation cup (4) directing the hot burned gas so that it remains out of contact with the nozzle (2);
• and
• a component to be heated (5, 6, 7) positioned at the second end (22) of the nozzle (2);
• wherein the component to be heated that is a dehorning tip (5) forms a reversible tool comprising a body having two extremities, the two extremities each forming a working face (51, 52) and the two extremities each configured to be fixed to the second end (22) of the nozzle (2), and
• wherein each of the two working faces (51, 52) of the dehorning tip (5) comprises a concave housing (511, 521) for receiving a horn core, each concave housing (511, 521) having a circular outer edge (5111, 5211) corresponding to one face of the dehorning tip (5), the diameters of the circular outer edges (5111, 5211) of each of the concave housings (511, 521) being different,
• wherein the nozzle (2) extends between the first end (21) and the second end (22) along a longitudinal axis (AA), and
• wherein the cup (4) comprises a lower annular component (41) and an upper annular component (42), the lower (41) and upper (42) annular components being coaxial and form a conduit (43) for orienting hot air in a direction substantially perpendicular to the longitudinal axis (AA), the conduit (43) being spaced relative to the jet (27),
• wherein each of two working faces (51, 52) of the dehorning tip (5) comprises a concave housing (511, 521) for receiving a horn core, each concave housing (511, 521) having a circular outer edge (5111, 5211) corresponding to one face of the dehorning tip (5), the diameters of each of the circular outer edges (5111, 5211) of the concave housings (511, 521) being different.
