Pneumatic dismantling device

A pneumatic dismantling device, including:

• a main body, including a compartment space, a chamber, an air intake portion and an assembling portion, a first end of the compartment space being closed by a radial wall, the radial wall and the main body being integrally formed of one piece, the chamber being located between and in communication with the compartment space and the assembling portion, an end of the chamber opposite to the radial wall being closed by the assembling portion, a hammer block being slidably received in the compartment space, a valve body being disposed in the chamber, the air intake portion being in communication with the chamber, the air intake portion being configured to be in communication with a high pressure gas source to make the valve body on or off reciprocatingly so that the hammer block is driven by the high pressure gas source to reciprocate in the compartment space;
• a disassembling assembly, including a position-limiting member and a connection member, the connection member being rotatably assembled to the assembling portion and isolated from the chamber by the assembling portion, the position-limiting member being assembled to the assembling portion and blocking the connection member, the connection member being configured to be assembled with a dismantling tool.
