    • A pipe boring device (1) including a housing (2)for receiving a self-tapping ferrule insert and a strap (3, 4) for securement around a pipe (10) to enable a hole to be bored into the pipe(10) by the ferrule insert. The strap (3, 4) includes first and second strap portions(3, 4) pivotally secured at a first of their ends (30, 40) by a connector (5). The first strap portion (3) includes a pair of slots (35a, 35b) along its length, which terminate at a second end (34) of the first strap portion (3) to form slot ends (36a, 36b). The second strap portion (4) includes three pairs of hooks (45a, 45b, 46a, 46b, 47a, 47b) along its length, which are receivable within the slots (35a, 35b) and configured to engage the slot ends (36a, 36b). The strap (3, 4) is configured to be wrapped around a pipe (10) with the first strap portion (3) overlapping the second strap portion (4) such that the second strap portion (4) is between the first strap portion (3) and the pipe (10) and one of the hook pairs (45a and 45b, 46a and 46b, 47a and 47b) is in engagement with the slot ends (36a, 36b). Each hook pair (45a and 45b, 46a and 46b, 47a and 47b) is spaced one from the next along the length of the second strap portion (4) such that the strap (3, 4) defines an opening for receiving the pipe (10) that is dependent upon which of the hook pairs (45a and 45b, 46a and 46b, 47a and 47b) is in engagement with the slot ends (36a, 36b).
    • 一种管镗孔装置(1),其包括用于接收自攻套管插入件的壳体(2)和用于固定在管(10)周围以使钻孔能够钻进管(10)中的带(3,4) 通过套箍插入。 带(3,4)包括通过连接器(5)枢转地固定在其第一端(30,40)处的第一和第二带部分(3,4)。 第一背带部分(3)沿其长度方向包括一对狭槽(35a,35b),终止于第一背带部分(3)的第二端部(34)以形成狭槽端部(36a,36b)。 第二带部分(4)沿其长度包括三对钩子(45a,45b,46a,46b,47a,47b),它们可容纳在槽缝(35a,35b)内并且构造成与槽缝端部(36a, 36B)。 带(3,4)构造成围绕管(10)缠绕,其中第一带部分(3)与第二带部分(4)重叠,使得第二带部分(4)位于第一带部分 3)和管子(10)以及钩对(45a和45b,46a和46b,47a和47b)中的一个与槽端(36a,36b)接合。 每个钩对(45a和45b,46a和46b,47a和47b)沿着第二带部分(4)的长度彼此间隔开,使得带(3,4)限定用于接收管的开口 这取决于钩对(45a和45b,46a和46b,47a和47b)中的哪一个与槽端(36a,36b)接合。
