The effect of the handle (or brush head) is improved. The conventional toothbrush has only a single type of bristles and a fixed length, which causes a lack of use and portability.

According to the above main structural features, the recess includes a shaft hole and an end groove communicated from the shaft hole to the end side of the handle, and the shaft portion is buckled into the shaft hole by the end groove.

According to the above main structural features, the first end of the handle is provided with a fixing hole, and the shaft portion is disposed in the fixing hole.

According to the above main structural feature, a receiving groove is disposed between the first end and the second end of the handle, the shaft portion is in the first end receiving groove, and the handle can be folded in the handle Set in the slot.

According to the above main structural features, the two sides of the second end receiving groove are respectively provided with an enlarged diameter edge portion corresponding to the brush head.

According to the above main structural features, the enlarged diameter edge portion is provided with a concave concave edge.

According to the above-mentioned main structural feature, a fastening portion is formed on the end side of the handle on the proximal side of the recess, and the receiving groove is formed at the first end with a buckle portion that can fasten the fastening portion.

According to the above main structural features, the fastening portion is a protrusion, and the buckle portion is an inner wall of the first end receiving groove.
