The utility model discloses a circuit board with a protective shell, which comprises a circuit board main body and a protective shell arranged above the circuit board main body, and the bottom of the protective shell is fixedly connected with a bottom frame along the edge of the protective shell. Two pneumatic buffer assemblies for supporting the bottom frame and the circuit board main body to a certain height are symmetrically arranged on the upper surface of the circuit board main body, and supporting assemblies for supporting and protecting the circuit board main body when the protective shell is pressed are arranged on the two sides of the pneumatic buffer assemblies. A bottom frame at the bottom of a protective shell pushes a first push rod to further compress a first spring, the first spring plays a buffering role, the first push rod pushes a first plug block to compress air in a first air cylinder, and after the air in the first air cylinder is compressed, the compressed air can be guided into a second
