In the past, when reinstalling the oil nipple, the oil nipple was easy to take off the tool, and it was not easy to lock the oil nipple back. With the improvement of the new style tool, there is a fixing screw on the upper side of the front of the tool, which can be locked once after the oil nipple is installed with the tool. Then lock back.
