PROBLEM TO BE SOLVED: To solve the following problem involved in a conventional cutting appliance for acetylene: it is necessary to grip a flexible rubber hose firmly because the rubber hose is bent by the weight of the cutting appliance and hung downward when griping the rubber hose, however the rubber hose is not easy to grip.SOLUTION: Hose nozzles 3a are lengthened long and are held from both sides with a plastic tool 1 so as to be easily held. The rubber hose 2 which is cut laterally is inserted into the hose nozzles so as to prevent play in a gap between the plastic tool and the hose nozzles. In this way, the hose is made easy to grip and held loosely. |
