Description

Technical Field

[0001] The utility model relates to an auxiliary tool which is convenient for manually rotating a workpiece after clamping. Background Art

[0002] There are two main methods for disassembling threaded parts on ordinary lathes or CNC lathes in the existing technology:

[0003] The first method is the manual tightening method, in which the operator holds the mating part with his hand and loosens the threaded fitting by the strength of his palm, thereby disassembling the mating threaded workpiece. However, it is difficult for the operator to tighten it by hand.

[0004] The second method is the knocking method, which uses a copper rod or plastic rod to knock on the end face of the mating part to achieve the effect of loosening the threaded fit, and then loosen and disassemble the mating threaded part by hand. There is a problem that light knocking will not loosen it, but strong knocking will easily cause damage to the threaded fit. Utility Model Content
