Toothbrush

A toothbrush, comprising:

• a handle placed upright and whose long sides extend vertically;
• a head having bristles for brushing teeth;
• a connection structure comprising a first rotating disc and a second rotating disc which are arranged coaxially and rotatable relative to each other, the first rotating disc being connected to the head or handle and the second rotating disc being connected to the handle or head, and a rotation axis of the first rotating disc and the second rotating disc being perpendicular to an extension direction of the handle;
• and
• an elastic structure comprising a first elastic member and a second elastic member, both the first elastic member and the second elastic member are strip-shaped structures and integrally provided, wherein the first elastic member and second elastic member are connected to or abutted against the first rotating disc at their first ends, the first elastic member and second elastic member are connected to the second rotating disc at a connection of the first elastic member and the second elastic member;
• and
• when the first rotating disc rotates relative to the second rotating disc under an action of an external force, at least one of the first elastic member and the second elastic member elastically deform to generate an elastic restoring force that drives the first rotating disc to rotate reversely to return to its initial position after the external force is removed,
• the rotation axis is parallel to an extension direction of the bristles.
