    • A pre-bracing tube of a cold shrinking sleeve includes a tubular body made integrally of plastic. The tubular body has its outer circumferential wall forming a spiral and successive tearing groove and a spiral and successive belt body between every two tearing grooves when the tubular body is shaped. Thus, when the tubular body is torn along the tearing grooves, the belt bodies can be drawn and takes advantage of an opportunity to draw the torn portion out of the tubular body. The tearing groove of the tubular body is formed when the tubular body is injection molded so it is needless to carry out any processing to the tubular body for obtaining a finished product, easy in manufacturing, convenient in production and able to lower cost. In addition, various molds can be made for matching with requirements of different diameters or lengths.
    • 冷收缩套管的预支撑管包括由塑料制成的管状体。 当管状体成形时,管状体的外周壁形成螺旋状和连续的撕裂槽,并且在每两个撕裂槽之间形成螺旋且连续的带体。 因此,当管状体沿着撕裂槽撕开时,可以拉动带体并利用机会将撕裂部分拉出管状体。 当管状体注射成型时,形成管状体的撕裂槽,因此不需要对管状体进行任何加工以获得成品,制造容易,生产方便且能够降低成本。 此外,可以制造各种模具以匹配不同直径或长度的要求。
