DISPLACEMENT APPARATUS AND VEHICLE MARKING DEVICE

The present application provides a displacing apparatus and an automobile calibration device. The displacing apparatus includes a guide rail and a displacing assembly. A first guide groove and a second guide groove are formed on a surface of the guide rail. The displacing assembly comprises a first rolling mechanism, a second rolling mechanism and a connecting portion. The first rolling mechanism and the second rolling mechanism are mounted to the connecting portion. The first rolling mechanism is rollably mated with the first guide groove and the second rolling mechanism is rollably mated with the second guide groove. The first rolling mechanism and the second rolling mechanism are jointly clamped on the guide rail and are rollable relative to the guide rail. In the technical solutions of the present application, the first rolling mechanism and the second rolling mechanism are jointly clamped on the guide rail and are rollably mated with the guide rail, so that the displacing assembly can be moved smoothly relative to the guide rail and the displacing assembly can be firmly assembled to the guide rail.
