[0004] This device uses a lubricating oil-soaked cotton layer to apply lubricating oil to the outer wall of the tool. However, the lubricating oil-soaked cotton layer will age after a period of use, making it impossible to restore its original shape. As a result, after the tool is inserted into the support cylinder of the lubricating oil layer, the lubricating oil-soaked cotton layer cannot contact the surface of the tool, which will affect the lubrication effect of the tool.

[0005] Therefore, in order to solve the above problems, a cemented carbide single-blade tool with a self-lubricating groove structure is proposed. Utility Model Content

However, the lubricating oil soaking cotton layer will age after a period of use, making the shape of the lubricating oil soaking cotton layer unable to be restored. As a result, after the tool is inserted into the soaking cotton layer support cylinder, the lubricating oil soaking cotton layer cannot contact the surface of the tool, which will affect the lubrication effect of the tool.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cemented carbide single blade with a self-lubricating groove structure, comprising: a base, a bracket mounted on the top surface of the base, a guide rod mounted on the inner side of the bracket, a threaded rod movably mounted on the inner side of the bracket via a thread, a motor mounted on the top surface of the bracket, and a lifting block slidably mounted on the outer side of the guide rod; The lifting block is equipped with a positioning structure, which includes a fixing rod.
