[0029] Referring to the above, when in use, the winding roller 3 is moved in the horizontal direction, the convex strip 7 corresponds to and is completely inserted into the groove 6, the winding roller 3 is completely located on the rotating rod 2, and finally the locking nut 8 is tightened and contacted with the winding roller 3 to complete the installation of the winding roller 3.
