The surface of the threaded clamping rod is threadedly connected to a threaded sleeve, and the top of the threaded sleeve is fixedly connected to the bottom of the roller.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model can conveniently separate the shaft head from the roller. When separating, it is only necessary to rotate the handle counterclockwise, so that the threaded clamping rod moves to the right side in the threaded sleeve, so that the threaded clamping rod disengages from the clamping slot, and then pull the baffle upward to drive the limit block to move upward, so that the limit block disengages from the second through slot, the limit opening and the first through slot, so that the limit block is removed, and then pull the shaft head to the left, so that the insert block disengages from the slot, so that the shaft head and the roller can be separated.
