[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The heat generated by the servo motor body during operation can be conducted out through the provided heat sink. At this time, the guide seat and the guide plate conduct the cold source generated by the cooling end of the cooling plate to the cold liquid to cool the cold liquid, so as to utilize the contact between the cooled cold liquid and the heat sink that conducts the heat for cooling. At the same time, under the action of the expansion plate, the contact area with the cold liquid can be further increased to fully reduce the working temperature of the servo motor body, so that the servo motor body will not overheat when running for a long time in a high temperature environment, thereby extending the working time and improving the working efficiency.

[0016] 2. Through the provided agitator, the No. 1 push flow plate can be driven to rotate under the action of the rotating No. 1 shaft, so that the cooling liquid in the area between the heat sink and the expansion plate can be pushed forward by the No. 1 push flow plate rotating in the front to be discharged from the front. At this time, the No. 2 push flow plate and the No. 1 push flow plate on the No. 2 shaft rotate in opposite directions to push the cooling liquid in the area between the guide seat and the guide plate backward, and cooperate with the rotating No. 1 push flow plate at the rear to push the cooling liquid from the rear into between the heat sink and the expansion plate, so as to circulate and avoid the phenomenon of temperature increase of local cooling liquid due to long-term contact with the cooling fin and the expansion plate, so as to ensure the constant temperature of the cooling liquid.

[0017] 3. When the rotor of the servo motor body is rotating, it will drive the No. 1 shaft to rotate synchronously through the No. 2 synchronous belt, the transmission shaft and the No. 1 synchronous belt. At this time, the No. 2 shaft and the No. 1 shaft are driven to rotate in the opposite direction with the cooperation of the No. 1 gear and the No. 2 gear. This ensures that when the servo motor body is working, the No. 2 shaft and the No. 1 shaft are in operation to allow the cooling liquid to circulate, avoiding the phenomenon that the local cooling liquid temperature rises due to forgetting to start the No. 2 shaft and the No. 1 shaft due to the separate setting, thereby causing the cooling force of the heat sink and the expansion plate to decrease, thereby ensuring the cooling force during work. At the same time, the present application is also provided with a shock absorbing mechanism. When the servo motor body drives the related structures to operate and transmit, the setting of the shock absorbing mechanism can effectively reduce the vibration and noise problems caused by the operation of the servo motor and multiple transmission shafts, thereby improving the operation stability and safety performance of the device.

At the same time, when the servo motor body 1 is operating, the transmission shaft 11, the No. 1 synchronous belt 12, the No. 1 gear 12 and other related mechanisms inside the servo motor body 1 will generate vibration force when operating. The vibration force is transmitted downward through the placement plate 371, and drives the telescopic column 372 to move downward and squeeze the spring 373. While moving downward, it will drive the six connecting rods 377 to rotate slightly to disperse and offset the vibration force, so as to effectively reduce the vibration and noise problems caused by the operation of the servo motor body 1, and improve the operation stability and safety performance of the device.
