In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

A heat dissipation port is provided on the heat dissipation shell, which can achieve the effect of rapid heat dissipation.

[0023] Wherein, a plurality of main heat dissipation fins 11 are fixed at intervals on both sides of the driving power source body.

The driving power supply body is placed in the placement area of ​​the heat dissipation shell, and the auxiliary heat dissipation fins are abutted against the upper and lower ends of the driving power supply body.

The thickness of the main heat dissipation fins is originally smaller than the width of the heat dissipation channel, so that the heat can be better discharged through the heat dissipation channel to the heat dissipation port, thereby accelerating the heat dissipation.

[0026] During implementation, the heat dissipation shell is fixedly installed with a limiting half cylinder and a supporting half cylinder 13 facing the connecting wire. The limiting half cylinder and the supporting half cylinder are fixedly installed on the upper shell and the lower shell respectively.

[0028] In this way, during installation, the driving power supply body is placed in the lower shell, the lower end of the driving power supply body is abutted against the auxiliary heat dissipation fins, and bolts are passed through the clearance holes on the lower mounting plate and connected to the lower internal threaded tube. Then, the upper shell is placed on the lower shell, and bolts are passed through the through holes and through holes and connected to the upper internal threaded tube for easy disassembly and assembly.

[0029] Specifically, a limiting rib is provided on the inner side of the lower shell, and a protrusion is provided on the outer side of the upper shell, so that the lower shell and the upper shell can be positioned.
