Description

Set one's teeth on edge rotating knife

Technical field

The invention mainly relates to a kind of rotating knife, rotating knife of espespecially setting one's teeth on edge.

Background technology

Again to treat that locked assembly is sheathed on bolt and with nut after bolt, which is used, to be arranged on fixation kit When being screw-locked at the occupation mode of bolt, the end of bolt may get rusty, accumulation dirt, even be hit by foreign object Hit and recessed damage deformation, cause nut can not smoothly lock bolt, when meeting above-mentioned condition, the practice typically adopted It is that bolt is cut again using screw plate, to cut off the iron rust on bolt, dirt or recessed damage position.

However, when bolt produces above mentioned problem, can simply cause nut to be stuck in bolt end, its remaining part Position still is able to normally use, if being solved the above problems using screw plate, screw plate needs completely before cutting It is directed at the screw thread of bolt, it is ensured that cutting route is consistent with the screw thread of original presence, it is necessary to expend the more time, Inefficiency.

The content of the invention
