All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

In the following description, the terms "left", "right", "upper", "lower", "front", "rear", "inner" and "outer" are relative terms, and are not intended to be exhaustive.

A brake for ease of maintenance, referring to figure 1, comprises a mounting disc 1. An opening is arranged at the center of the mounting plate 1. The mounting disc 1 is rotatably provided with a mounting ring 3 on an opening. The mounting plate 1 is provided with a cover 4. The mounting plate 1 is provided with fixing bolts 44 on both left and right sides. The fixing bolts 44 are used to connect the mounting plate 1 and the cover 4. The number of the fixing bolts 44 may be three, four, etc. as long as it does not affect the removal of the limiting plate 6 and the friction plate 2, for those skilled in the art.
