The clamping block on the outer wall of the elbow cutting nozzle body will first squeeze the clamping plate, so that the clamping plate is displaced on the inner wall of the slide groove provided on the sleeve. When the clamping plate is displaced, the spring is squeezed to form a compressed state. At this time, the telescopic rod and the telescopic cylinder supporting the spring also change, and the telescopic rod retracts into the telescopic cylinder. When the clamping block completely enters the interior of the shell, the elastic force of the spring resets the clamping plate, so that the clamping block cannot be pulled out inside the shell. Through this design, the elbow cutting nozzle can be quickly replaced and installed, without the staff having to twist the elbow cutting nozzle several times to complete the installation, which greatly reduces the time for replacing the elbow cutting nozzle to the cutting torch head and also reduces the labor intensity, with good use effect.

[0019] 2. In the utility model, a quick-release assembly is provided. When replacing a new elbow cutting nozzle body, it is necessary to pull the pull block first. The pull block drives the pull rod to move. The pull rod runs through the inside of the telescopic rod and the telescopic cylinder. When the pull rod moves, it drives the snap plate to move. The snap plate squeezes the spring to form a compressed state. The telescopic rod retracts into the inside of the telescopic cylinder, so that the snap block has enough space to be pulled out from the inside of the shell. Through this design, the old elbow cutting nozzle can be quickly removed from the cutting torch, which further improves the convenience of replacing the elbow cutting nozzle and has a good use effect.
