The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "in communication" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 3, a round nut detacher, including expansion disc 1, expansion disc 1 has a plurality of draw-in grooves 2 towards the 1 centre of a circle of expansion disc, in this embodiment, is provided with four evenly distributed's draw-in grooves 2 on the expansion disc 1, installs in the draw-in groove 2 and can follow the gliding checkpost 3 of draw-in

groove
