Toothbrush

A toothbrush, comprising:

• a head, a handle, and a first rotating structure, wherein the head has a rotation axis extending in a length direction;
• the first rotating structure comprises a rotating member connected to the head and a connecting member connected to the handle, a surface of the connecting member facing the head is provided with an insertion groove extending along the rotation axis, and an end of the rotating member facing away from the head is inserted into the insertion groove and is rotatably connected to the connecting member;
• the rotating member is provided with a first snap-fit member, and the connecting member is provided with a plurality of second snap-fit members, the first snap-fit member is capable of passing over each second snap-fit member in sequence while rotating along with the rotating member, and is snap-fitted with any one of the second snap-fit members to limit the rotation of the rotating member when opposite the second snap-fit member;
• or the rotating member is provided with a plurality of first snap-fit members, and the connecting member is provided with a second snap fit member, the first snap-fit members are capable of passing over the second snap-fit member in sequence while rotating along with the rotating member, and any one of the first snap-fit members is snap-fitted with the second snap-fit member to limit the rotation of the rotating member when opposite the second snap-fit member,
• said toothbrush further comprising a second rotating structure and an elastic structure, wherein the connecting member is connected rotatably about a bending axis to the handle via the second rotating structure, the bending axis is perpendicular to the rotation axis, and the elastic structure is configured to be elastically deformed when the connecting member rotates about the bending axis;
• wherein the second rotating structure comprises a first rotating disk connected to the connecting member and a second rotating disk connected to the handle, and the first rotating disk and the second rotating disk are coaxially arranged and are rotatable relative to each other along the bending axis;
• the elastic structure comprises a first elastic member formed by connecting a first arm to a second arm, ends of the first arm and the second arm that are connected to each other are fixed-ends connected to the first rotating disk, free ends of the first arm and the second arm both abut against or are connected to the second rotating disk, and when the first rotating disk and the second rotating disk rotate, the elastic structure is elastically deformed.
