Three-direction adjustable thermal-insulation blast burner applicable to OVD (outside vapor deposition) process

The invention discloses a three-direction adjustable thermal-insulation blast burner applicable to OVD (outside vapor deposition) process. The blast burner comprises a pole component, a blast burner body, a blast burner vertical lifting mechanism, a blast burner horizontal moving mechanism and a blast burner angle adjusting mechanism. The blast burner vertical lifting mechanism controls the pole component to rotate around a point to realize vertical lifting of the blast burner; the blast burner horizontal moving mechanism controls horizontal movement of the pole component to realize horizontal movement of the blast burner body; the blast burner angle adjusting mechanism changes an angle between a head base and the pole component to realize angle adjustment of the blast burner. The three-direction adjustable thermal-insulation blast burner has functions of vertical lifting, bilateral movement and rotation, and real-time thermal preservation of soot perform ends can be realized by oxyhydrogen flames of the ther
