A pluggable apparatus of a circuit board is provided, which solves the problem that hot plugging of a Peripheral Component Interconnect Express (PCI-E) card is difficult to implement. The pluggable apparatus of the circuit board includes a base plate, a pulling strip, a rotating member, and a carrier plate, where the pulling strip is movably connected to the base plate by using a transverse guide mechanism, sawteeth are formed on a body of the pulling strip, the pulling strip further includes a handle that extends out of the base plate; the rotating member is in a bending line shape; the carrier plate is movably connected to the base plate by using a longitudinal guide mechanism; and a clamping trough is disposed on the carrier plate and is configured to fasten the circuit board.
