Rubber roller

The utility model discloses a rubber roller which comprises clamping devices, an outer shaft sleeve and a combination shaft, the outer shaft sleeve is connected outside the combination shaft in an embedded mode, and the clamping devices are arranged at the two ends of the combination shaft. When the main telescopic clamping shaft is compressed by the connecting clamping shaft above, the connecting clamping shaft is pulled to enter the base clamping shaft in a matched mode, so that the overall contraction work of the clamping device is completed, at the moment, the clamping device and the combined shaft connected with the outer shaft sleeve can be placed into film pasting equipment, and therefore the replacement work is rapidly completed; the problem that the rubber roller is troublesome to replace is avoided, when the outer shaft sleeve outside the rubber roller needs to be replaced, only the outer shaft sleeve needs to be pulled out of the combined shaft, the extending clamping strips at the two ends of the
