In this embodiment, the limiting member 10 includes at least two limiting arms 12 and a blocking member 13 connected to the two limiting arms 12, and each limiting arm 12 is provided with a set of adjustment holes 11.

Specifically, the limiting arms 12 may be, but not limited to, made of carbon steel or stainless steel, the number of the limiting arms 12 is preferably two, and two sides of the output end of the motor 101 at the position of the two limiting arms 12 are symmetrically arranged, the baffle 13 is located in front of the output end of the motor 101 and keeps a certain distance, two ends of the baffle 13 are fixedly connected with the two limiting arms 12 respectively, the baffle 13 can be used as a supporting and stabilizing structure of the limiting arms 12, and can also be used as a reference object of the cutting depth of the grinding disc 102, because the positions of the baffle 13 and the limiting arms 12 are fixed, the center of the baffle 13 and the far end of the grinding disc 102 are located on the middle interface of the angle grinder, and the distance is easy to measure. Of course, in some embodiments, the number of spacing arms 12 may be 3, 4, or more, with the number of holders 20 and fasteners 30 corresponding to the number of spacing arms 12.

In this embodiment, the limiting member 10 further includes a roller 14 disposed at an end of the limiting arm 12.

Specifically, the number of the rollers 14 is preferably 2, the rollers 14 are respectively connected to the end parts of the limiting arms 12 in a centering and rotating manner, and move along the surface of the workpiece when the angle grinder cuts, and the rollers 14 roll on the surface of the workpiece at this time, so that the resistance can be reduced, and the labor can be saved.

In this embodiment, referring to fig. 3, the blocking member 13 includes a middle straight section 131 and two connecting sections 132 bent to one side, and the two connecting sections 132 are fixedly connected with the two adjacent limiting arms 12 respectively.
