SPIRAL TUBE FOR PRESSURE-SUPPORTING AND EASY PULL-OUT

摘要

A strip-connecting type spiral tube is configured so that strip members serving as segments are connected to each other. The strip-connecting type spiral tube for pressure-supporting and easy pull-out has a new-type connection structure of strip members, which allow easy and convenient pull-out of strip members adjacently connected and prevents an arrangement of strip members from collapsing due to an external pressure.
