The present invention discloses a retractable electric toothbrush. The present invention discloses a retractable electric toothbrush, includes a columnar body, and a storage chamber is installed in the columnar body, and slide block chambers are provided on both upper and lower end walls of the storage chamber. The expansion/contraction mechanism can store the expansion/contraction rod, and the expansion/contraction mechanism of this device can store the expansion/contraction rod in the storage chamber, which reduces the space occupied by the toothbrush and is convenient for storing the toothbrush. Since the large pulley has a larger diameter than the small pulley, it can be rotated at a high speed by the small pulley, that is, it can be rotated at a high speed by the brush plate, improving the brushing efficiency, and this device has an excellent design. However, the transmission structure is simple and it is difficult for failures to occur. [Selection diagram] Figure 1【課題】本発明は収納可能の電動歯ブラシを開示した。【解決手段】本発明は収納可能の電動歯ブラシを公示し、円柱体を含み、前記円柱体の中には収納チャンバが設置され、前記収納チャンバの上下両側の端壁にはいずれもスライドブロックチャンバが設置され、前記伸縮機構は伸縮棒を収納でき本装置の伸縮機構は伸縮棒を収納チャンバの中に収納でき、歯ブラシの占有空間を減らし、歯ブラシの収納に便利であり、また、動力機構において、大型プーリは小型プーリより直径が長いため、小型プーリに高速回転させることができ、すなわちブラシ盤にも高速回転させることができ、歯磨きの効率を上げ、さらに、本装置は優れた設計を有し、伝動構成が簡単で、故障が発生しにくい。【選択図】図１
