Pressure pipeline detection auxiliary device

The utility model belongs to the technical field of auxiliary devices, and relates to a pressure pipeline detection auxiliary device which comprises a movable box, a pressure sensor is arranged in the movable box, a first movable bin is arranged in the movable box, and a first bearing is arranged on the surface of the first movable bin in a penetrating mode. When people need to maintain the pressure sensor, people only need to rotate a rotating disc, so that a first rotating shaft can be driven to rotate, meanwhile, a first bevel gear can be driven to rotate, and under the mutual meshing of the first bevel gear and a second bevel gear, a second rotating shaft can be driven to rotate; and meanwhile, a first threaded column can be driven to rotate, and a clamping rod can be driven to move under the interaction of the first threaded column and a threaded pipe, so that the clamping rod can be separated from the pressure sensor, the pressure sensor can be maintained, and people can maintain the pressure sensor mor
