The invention relates to a compact oil pipe protecting device for an operating table. The compact oil pipe protecting device comprises a metal protecting hood, wherein an oil pipe inlet groove and an oil pipe outlet groove are respectively formed on two sides of the metal protecting hood, and hairbrushes are arranged on the oil pipe inlet groove and the oil pipe outlet groove; an integrally-designed rear baffle is arranged at the rear end of the metal protecting hood; a detachable front baffle is arranged at the front end of the metal protecting hood; and at least one strut member, particularly, three strut members are arranged inside the metal protecting hood. With the protecting hood structure, in the motion process of the operating table, the oil pipe can move in the enough space so asnot to collide other parts on the operating table and avoid the damage; the hairbrushes are arranged at the oil pipe inlet groove and the oil pipe outlet groove and can be convenient for the oil pipeto move in the grooves; moreover, when fingers of workers extend into the oil pipe inlet groove and the oil pipe outlet groove, the hairbrushes can remind the workers.
