During the maintenance of the machine tool, several countersink pins are often encountered at the same time, as shown in Figure 1. Usually, we use the pullout device of the disassembly tool as shown in Figure 2. When removing the pin, string the nut sleeve 1 on the screw (not shown), then screw it into the screw hole of the pin, and then screw the nut sleeve onto the tie rod. When disassembling another pin, it is necessary to pull the nut from the pull.
