[0028] Before using the motor, first install the mounting mechanism 5 at an appropriate position, and then install the motor body on the mounting mechanism 5 through the connecting component 6 to fix the motor body, or directly remove the mounting mechanism 5 and use the connecting component 6 to directly fix the motor body at an appropriate position, so as to better install the motor body, and then the motor can be used;

[0029] The motor body is equivalent to the brushless motor in the prior art, and is composed of a shaft 1, a motor lower shell 2, a motor upper shell 3, a hexagon socket screw 4, a bearing 7, a magnet 8, and a stator 9.

[0030] like Figure 3 As shown, the mounting mechanism 5 includes a U-shaped plate 59 and a mounting positioning plate 51. The left side of the U-shaped plate 59 overlaps with the right side of the motor lower shell 2, and the bottom of the U-shaped plate 59 is fixedly connected to the right part of the mounting positioning plate 51. A through groove body 54 is opened in the middle of the mounting positioning plate 51.
