[0028] Further, if Figure 1 and Figure 3As shown, the motor 5 is located in the middle of the base frame 1 , and the voltage adapter 3 is located on the outer side of the base frame 1 , so that a distance L is formed between the motor 5 and the voltage adapter 3 .

[0029] Specifically, the spacing reference of the motor 5 is the spacing L formed by the axis of the output shaft of the motor 5 and the voltage adapter 3; the distance between the voltage adapter 3 and the motor 5 is further increased, which reduces electromagnetic interference and improves the working stability of the motor 5 and the voltage adapter 3; the voltage adapter 3 is arranged on the outer side and uses natural convection or an external fan to dissipate heat, effectively preventing failures caused by high temperature; at the same time, it is also convenient for quick inspection and maintenance to ensure the long-term stable operation of the equipment.

[0041] Specifically, the box body 401 and the upper cover 402 are connected by a fastening structure, so that the upper cover 402 can be firmly fixed on the box body 401 to prevent loosening caused by external factors;

[0042] Alternatively, the box body 401 and the upper cover 402 are connected by a flip structure, so that the upper cover 402 can be flipped open and closed relative to the box body 401.
