The local pulsar and its progenitor, SNR, can together accelerate thepositron, electron and nuclei to very high energy. The famous excesses ofpositron(nuclei) above $20$($200$) GeV possibly come from such kind of localsource. This hints that the primary electron should also hold "excess" above$200$ GeV, synchronously accelerated along with the nuclei. The recent precisemeasurement of sharp dropoff at 284 GeV of positron by AMS-02 experiment takeschance to study this expected electron excess. In this work, thespatially-dependent propagation with a local source is used to reproduce thespectrum of positron, electron and proton. When considering the dropoff at 284GeV of positron, a sharp bump structure for primary electron above 284 GeV isrequired to fit the total spectrum of positron and electron. Then wesystematically study the common origin of the excesses of positron, electronand nuclei from Geminga pulsar and SNR. Those excesses can be reproduced underthis unified single-source model. Lastly, we hope that the fine bump structurecan be observed to support our model by AMS-02 experiment in future.
