Vacuum pump for cell room

The invention discloses a cell room vacuum pump, and relates to the field of vacuum pumps, the cell room vacuum pump comprises a base, the top side of the base is movably provided with a bottom plate and a driving motor, and the top side of the bottom plate is movably provided with a rotary vane type vacuum pump body. When a driving motor breaks down, two adjusting motors are started to enable a limiting lantern ring to be separated from a vacuum pump shaft and a connecting rotating block, at the moment, an arc-shaped clamping block is overturned to be separated from the vacuum pump shaft, connection between the driving motor and the vacuum pump shaft can be disconnected, and then a pushing air cylinder is started to control a linkage rotating ring to move; the movable clamping block is turned over and clamped into the connecting clamping groove, then the standby motor is started, the standby motor drives the vacuum pump shaft to rotate through cooperation of the linkage rotating ring and the movable clamping
