Referring to fig. 1 to 5, fig. 1 shows a schematic structural diagram of a tool according to an embodiment of the present utility model, fig. 2 shows a schematic structural diagram of another view of the tool according to fig. 1, fig. 3 shows a top view of the tool according to fig. 1, fig. 4 shows a front view of the tool according to fig. 2, and fig. 5 shows a state of use of the tool according to fig. 2 when the slip ring is detached, the tool 100 according to an embodiment of the present utility model is used for detaching and installing the slip ring 200, which improves the detachment efficiency of the slip ring 200, and achieves rapid detachment and installation of the slip ring 200. The tool 100 includes a base 300, a connector 400, and a knob 500. The connecting piece 400 penetrates through and is movably arranged on the base 300, and one end of the connecting piece 400 is used for fixedly connecting the collector ring 200. The knob member 500 is screw-coupled to the connection member 400 so as to be movable along the connection member 400, and the knob member 500 is positioned between the base 300 and the other end of the connection member 400.

In the tool 100 of this embodiment, the movable connecting piece 400 is disposed on the base 300, and the knob piece 500 in threaded connection is sleeved on the connecting piece 400, because one end of the connecting piece 400 can be fixedly connected with the collecting ring 200, when the collecting ring 200 tightly fitted on the rotating shaft 210 of the generator is disassembled, the knob piece 500 is screwed towards one end of the collecting ring 200, the knob piece 500 moves along the connecting piece 400 to apply a force to the base 300, the base 300 cannot move under the restriction of the rotating shaft 210 of the rotor to generate a reverse force, and the connecting piece 400 moves towards a direction away from the collecting ring 200 under the reaction force of the base 300, so that the collecting ring 200 is pulled out (pulled out) along the axial direction, and then the collecting ring 200 is removed from the rotating shaft 210 of the rotor. Therefore, when the tool 100 is used, after the collecting ring 200 and the connecting piece 400 are fixedly connected, the collecting ring 200 can be detached only by screwing the knob piece 500, so that the detaching efficiency of the collecting ring 200 of the generator is improved, and the requirement of quick detachment of the collecting ring 200 is met. In addition, the working mode of the tool 100 for installing the collecting ring 200 is opposite to the above-mentioned disassembling mode, and will not be described here again, the tool 100 also improves the installation efficiency of the collecting ring 200 of the generator, and meets the requirement of quick installation of the collecting ring 200.
