The implementation conditions adopted in the embodiments can be further adjusted as the specific manufacturer's conditions, and the implementation conditions not mentioned are usually the conditions in the conventional experiments.

[0040] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood as the common meanings understood by the persons with ordinary skills in the art to which the present application belongs.

[0041] In the present application, the orientations or position relationships indicated by the terms "upper", "lower", "inner", "middle" and the like are based on the orientations or position relationships shown in the drawings. These terms are mainly used for better describing the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0042] The application discloses a portable electric rubber tapping machine, which comprises a shell, a connecting component arranged at one end of the shell, a rubber knife arranged at the side of the shell away from the connecting component, an output shaft connected with the rubber knife, the output shaft being arranged in the shell, a driving component arranged in the shell, an output end of the driving component being connected with a speed change mechanism, the speed change mechanism being connected with a conversion assembly, and the conversion assembly being connected with the output shaft. The portable electric rubber tapping machine further comprises a cable and a power supply module. In use, one end of the cable is connected (for example, by being quickly inserted into a connecting terminal on the shell through a terminal) and the other end of the cable is connected to the power supply module (for example, a battery pack). The connecting component forms a locking structure of the cable, so that the cable can be quickly fixed and connected to the connecting terminal on the shell. An adding opening is arranged on the shell, and lubricating oil is directly added to the speed change mechanism through the adding opening, so that the shell does not need to be opened, and the complexity of maintenance is reduced (at present, the shell of the rubber tapping machine needs to be opened for adding lubricating oil during maintenance, and the lubricating oil needs to be added every 2-3 days during normal use, so that the operation is relatively complicated).

[0043] Next, the portable electric rubber tapping machine provided by the embodiment of the application will be described. Figures 1-12
