摘要:
本发明涉及一种柔性连接防振钻头机构,包括外管、内管、接头和钻头。外管由上下管体连接而成,内管安装在外管内。上管体内设有环形槽,内管的一端具有与环形槽相匹配的环形凸起,使凸起能够嵌入槽中并在其中移动。弹性元件放置在槽内,其两端分别抵靠在槽底和环形凸起的顶部。该防振钻头采用钻头与钻柱之间的柔性连接,有效防止在穿越硬层或软硬交错地层时因振动导致的切削齿损坏,从而延长钻头的使用寿命。

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
