Due to different product models, the deflection angle of the eccentric shaft is different. In the mass production process, this step is completed by positioning tooling. However, in the trial production stage, on the one hand, the cost of customized tooling is high, and on the other hand, during the trial production process, the eccentric shaft angle may need to be adjusted. The current general method is to manually combine the eccentric shaft and the rotor, and then use a measuring tool to measure it, and then adjust it. Since the angle is not measured directly, the measurement error is large and the installation accuracy is very low.

[0033] The surfaces of the upper cover 3 and the lower cover 4 are both provided with a dial 5 for indicating the installation angle of the eccentric shaft 22 .

[0034] Specifically, in this embodiment, the scale plate 5 is a circular scale plate 5. The circular scale plate 5 is distributed on the surface of the upper cover 3 and the lower cover 4. The actual deflection angle of the eccentric shaft 22 is uncertain. No matter how large the deflection angle is, the 360° circular scale plate 5 can indicate the installation angle of the eccentric shaft 22.

[0035] Specifically, in this embodiment, the scale plate 5 includes a plurality of indicator lines and digital marks corresponding to the indicator lines, and the indicator lines and digital marks are convex structures, concave structures or laser engraving mechanisms.

[0036] Specifically, in this embodiment, the eccentric shaft 22 is parallel to the central axis of the transmission shaft 21 and does not overlap.

[0037] Specifically, in this embodiment, the transmission shaft 21 and the eccentric shaft 22 are an integrally formed structure.

In actual implementation, the upper cover 3 and the lower cover 4 both have a dial 5 indicating the installation angle of the eccentric shaft 22.
