[0002] During the steel rolling process in steel mills, high-pressure descaling nozzles have been widely used. After a period of use, the high-pressure nozzle core needs to be replaced. Due to the interference of slag, the nozzle is inconvenient to pull out or cannot be pulled out. Therefore, the design is carried out to address this situation.

Usually, the device needs to be disassembled. However, traditional disassembly tools are pulled out by hand, which is easy to hurt the hands and is laborious. Therefore, a pneumatic pulling device is proposed to solve the above problems. Utility Model Content

[0018] The utility model has the following beneficial effects:
[0019] 1. In the utility model, the cylinder is the power source of the pneumatic pulling device. When gas is fed into the cylinder, the piston in the cylinder moves under the pressure of the gas, and the nozzle core is pulled out by utilizing the cylinder's stretching force.
[0020] 2. In the utility model, the air exchange valve is responsible for regulating the gas flow direction, determining whether the gas enters the cylinder from the compressed air source or is discharged from the cylinder. By changing the gas flow direction, the movement direction of the cylinder can be controlled, thereby achieving a controllable stretching or pulling operation. BRIEF DESCRIPTION OF THE DRAWINGS
