[0003] When controlling the extension and retraction of the hook of the EMU, there are usually three buttons that need to be turned manually. The operator needs to control the rotation of the three buttons in sequence. However, the positions of these three buttons are usually relatively inside, which is not conducive to direct operation by the operator. In addition, the brightness inside the EMU is low, which is not conducive to observation.

[0004] Therefore, it is necessary to design a coupler telescopic auxiliary tool. Utility Model Content

[0012] This technical solution elaborates the structure and composition of the marking component.

[0013] As a further solution of the present invention: the transmission assembly includes a knob rotatably arranged at one end of a long tube, a rotating shaft is fixedly mounted on the knob, the rotating shaft is rotatably arranged in the long tube, and the rotating shaft is rotatably connected to the adapter assembly at one end away from the knob.

[0014] This technical solution elaborates the structure and composition of the transmission assembly in detail.

[0015] As a further solution of the present invention: the adapter assembly includes an adapter shell fixedly mounted on the other end of the long tube, one end of the rotating shaft is rotatably connected to the inside of the adapter shell, a bevel gear 1 is fixedly connected to the rotating shaft, a bevel gear 2 is rotatably provided in the adapter shell and meshes with the bevel gear 1, a rotating head is fixedly mounted on the lower side of the bevel gear 2, and the rotating head is rotatably connected to the adapter shell.

[0017] As a further solution of the present invention: a handle is fixedly mounted on the outer side of one end of the long tube close to the knob.

[0018] In summary, the beneficial effects of the utility model are as follows: by setting the lighting, the internal structure can be observed more clearly; by setting the mounting assembly to stabilize the position of the long tube, by using the marking assembly to control the extension length of the long tube, by setting the transmission assembly and the adapter assembly to cooperate, the twisting of the knob is converted into the rotation of the rotating head, thereby realizing remote operation; by setting the marking line 2, the rotation angle of the rotating head can be more accurately judged.
