Claims

[Claims for Utility Model Registration] 1. A mounting tube 1 made of a hollow cylinder; a push-in tube 2 made of a hollow cylinder externally fitted onto the mounting tube 1 so as to be movable in the axial direction; and the mounting tube 1. It is inserted into the hollow part of the push-in tube 2 while keeping watertight, and the push-in tube 2 is inserted in the upper part.
a hollow operation shaft tube 3 that is engaged with the operation shaft tube 3 and has a rust-proof tube attachment part at its lower end; and a hollow operation shaft tube 3 that is inserted into the hollow portion of the operation shaft tube 3, with its upper and lower ends protruding beyond the operation shaft tube 3. an operating shaft 4 disposed in the direction of the operating shaft 4; a lifting mechanism for lifting the operating shaft 4 up and down in the axial direction by applying a reaction force to the pushing tube 2; and a lifting mechanism fixed to the lower end of the operating shaft 4; a clamping pressure body 6 having an inclined surface formed on its upper surface facing the lower end surface of the operating shaft cylinder 3; disposed between the lower end surface of the operating shaft cylinder 3 and the inclined surface of the clamping pressure body 6; and a rolling pressure member 7 made of a hard body which is interposed around the operating shaft 4 in a biased state in the diametrical direction and rolls outward when the clamping pressure body 6 is lifted up. A device for attaching a rust-proof tube to the branch port of a fluid pipe. 2. The fluid according to claim 1, wherein the lifting mechanism is an operating rod 5 having a cam surface 30 that comes into contact with the upper surface of the pushing tube 2, and the rotational center position of the cam surface gradually changes. Anti-rust tube device for pipe branch opening. 3. The apparatus for attaching a rust-proof tube to a branch port of a fluid pipe as set forth in claim 1, wherein the lifting mechanism is a hydraulic cylinder.
