Description
Extension Tool 1. Field of the Invention The present invention relates to an extension tool.
2. Description of the Related Art Referring to Taiwan Patent No.354003, a conventional bit A inserts in a chuck C of an power wrench B, and the chuck C drives the bit A to turn.
Sometimes, for adapting to various sizes of bits, another quick-release chuck would be installed.
However, when the drive shank 1 of the quick-release chuck is inserted in the chuck C, there will be an angle between the drive shank 1 and the axle of the chuck C. While turning the drive shank 1, the drive shank 1 would have a problem of swaying.
Summary of the Invention It is, therefore, the purpose of this invention to provide an extension tool including a shank body and a sleeve. The shank body includes a first end and a second end, wherein the first end thereof forms a working end provided for connecting the tool. The second end of the shank body defines a connecting end connecting to the power tool. A shank is formed between the first and second ends of the shank body. The sleeve is rotatably disposed on the shank of the shank body. While the shank body connects to a power tool and rotates with a power tool, a user could hold the sleeve and the sleeve would not rotate with the shank body. So that the user could be safe to operate the extension tool with a power tool in a high rotating speed and prevent from getting hurt.
