Coupling wheel drawing device and coupling wheel drawing assembly

The utility model provides a coupling wheel drawing device and a coupling wheel drawing assembly, and belongs to the technical field of coupling wheel dismounting devices. The coupling puller comprises a puller body and at least two lead screws, the puller body is provided with a first plate surface and a second plate surface which are opposite to each other, and a plurality of first bolt holes penetrating through the first plate surface and the second plate surface are formed in the puller body; each lead screw is used for correspondingly penetrating through one bolt hole and a second bolt hole formed in a bearing of the to-be-detached coupling, and the two ends of each lead screw are used for being fixed to the first plate face and the surface of the side, away from the second plate face, of the bearing of the to-be-detached coupling correspondingly. The coupling wheel puller is simple in structure and convenient to use, not only can the coupling wheel be quickly disassembled, but also the coupling wheel ca
