Abstract: The present invention is to provide a eraser wheel for cleaning viscose, which comprises a eraser wheel body and a coupling member. The eraser wheel body has an axial hole and a plurality of slots thereon. The axial hole is located at a central portion of the eraser wheel body. The slots are located beside the axial hole. The coupling member includes a coupling axle and a plurality of coupling ribs. One end of the coupling axle is provided with a connecting unit, and another end of the coupling axle is connected with the coupling ribs. The coupling axle is inserted through the axial hole. The coupling ribs are positioned in the slots. Accordingly, it is only required to replace with a new eraser wheel, without making a replacement of the coupling member. Besides, the eraser wheel can be produced alone, which simplifies the production procedure.

Abstract: A tire-patching tool and its patching method includes a pneumatic tool for producing a rotation force with a preset rotating speed, and a tire-patching needle with a tire seal strip assembled on the pneumatic tool to be driven into a broken hole of a tire. In using, the pneumatic tool is started to transmit a rotation force to the tire-patching needle so that the tire-patching needle can be vertically driven into the tire in the direction of the broken hole to let the tire seal strip stuck in the broken hole of the tire, and then remove out the tire-patching needle to finish tire patching work. By the pneumatic tool driving the tire-patching needle to produce a rotation force, the tire seal strip can quickly and accurately be stuck in the broken hole of the tire, saving time and labor in carrying out tire patching work.
