The utility model relates to the technical field of
drainage tubes in gynaecology and
obstetrics, in particular to a drainage tube angle adjusting device which comprises a heightening table, a connecting column is fixed to the middle of one side of a limiting plate, a fixing plate is fixed to the top of the other end of a supporting frame, and a
handle is inserted into the middle of the fixing plate in a sliding mode. Through cooperative use of the installation supporting frame, the limiting plate, the fixing plate, the
pipe supporting table, the
handle, the limiting column, the movable plate, the reset spring, the fluted disc clamping block, the connecting column, the limiting ring, the formed limiting groove and the formed positioning clamping groove, the angle of the
pipe supporting table can be rapidly adjusted, and the angle position of the
pipe supporting table can be rapidly fixed after the pipe supporting table is adjusted. Through the cooperative use of the pipe supporting table, the binding belt, the rotating
handle, the rotating rod and the rotating gear, the drainage pipe can be flexibly clamped and fixed according to the
diameter of the drainage pipe, and the drainage pipe is prevented from sliding randomly in the using process.
