具有磁控预载力的切割工具
摘要：
本公开涉及一种切割工具(100)，包括：外管状部件(101)，具有第一磁体(110)；以及内管状部件(103)，具有第二磁体(111)，其中，内管状部件可滑动地布置在外管状部件内。在第一磁体和第二磁体之间产生诸如吸引力的力。吸引力产生内管状部件和外管状部件之间的预载力。还公开了一种在内管状部件和外管状部件之间产生力的方法。
摘要（英）：

A cutting tool includes an outer tubular member having a first magnet and an inner tubular member having a second magnet wherein the inner tubular member is slidably disposed within the outer tubular member. A force, such as an attractive force, is created between the first magnet and the second magnet. The attractive force creates a preload force between the inner tubular member and the outer tubular member. A method of creating a force between an inner and outer tubular member is also disclosed.
