Embodiment 3

Referring to FIG. 7 , and based on the first embodiment, the heat dissipation mechanism 4 further includes a vertical plate 47, the vertical plate 47 is fixedly connected to the top of the base 6, the top of the vertical plate 47 is fixedly connected to a fixed plate 44, both sides of the top of the fixed plate 44 are fixedly connected to limiting members 43, and the number of limiting members 43 is two. By setting the limiting members 43, since the limiting members 43 are fixedly connected to the surface of the fixed plate 44, the distance between the two limiting members 34 is the same as the distance of the frame 46, thereby achieving the purpose of preliminary limiting the frame 46.

Furthermore, a slide groove is provided on the surface of the limit member 43, and a connecting rod 41 is slidably connected in the slide groove. Two connecting rods 41 are provided, and a frame 46 is fixedly connected between the two connecting rods 41. A cooling fan 45 is provided in the frame 46.

After the rear cover 23 is installed on the surface of the motor body 1, the motor body 1 is placed on the surfaces of the two support plates 31. At this time, under the gravity applied by the motor body 1, the two support plates 31 can be driven to slide on the surface of the fixing rod 35 in directions away from each other, and the spring 32 is squeezed at the same time. At this time, the angle between the first support arm 33 and the second support arm 39 is continuously increased. The spring 32 is provided to weaken the impact force generated by the motor body 1, thereby achieving the purpose of buffering.

When the motor body 1 needs to dissipate heat after working for a long time, the cooling fan 45 can be placed between the two limit members 43. When the connecting rod 41 is fully inserted into the slide groove opened inside the limit member 43, the cooling fan 45 can be positioned by threading the second bolt 42 into the inside of the limit member 43 and the frame 46, thereby realizing the installation of the cooling fan 45.
