In the detachable toothbrush head structure, the coupling part of the coupling rod further includes two coupling grooves, and the two coupling grooves are respectively provided with an O-ring.

In the detachable toothbrush head structure, the flange of the connecting part of the connecting rod is provided with a pair of parallel planes.

In the detachable toothbrush head structure, the tail end of the coupling rod is sleeved on a multi-folded end of a handle.

Another detachable toothbrush head structure of the present invention includes: a toothbrush head. The back of a body is provided with a combined hole groove body, and the combined hole groove body is provided with a pair of vertical through holes and a pair of horizontal through holes And a connecting rod, one end of a rod body is provided with a connecting part, and the connecting part is provided with a pair of integrally formed arc bodies and a positioning and bending connecting body, wherein the positioning and bending connecting bodies are connected to each other The pair of arc-shaped bodies are back to back to provide a combined hole and groove body that is clamped to the toothbrush head.

In the detachable toothbrush head structure, the tail end of the coupling rod is connected to a handle.

With the above technical means, the following effects can be achieved:

1. In the new model, the revolving cross bar, the O-ring and the flange in the multi-step rod body are inserted into the combing hole groove of the toothbrush head through the rotating cross bar, The flange is clamped into the fitting groove on the back of the toothbrush head, so that the toothbrush head and the coupling rod can be firmly combined.

2. This new model uses the two-arc body formed integrally with back-to-back and its positioning and bending connecting body set in the connecting part of the connecting rod to be inserted into the vertical through hole and the transverse through hole in the groove of the connecting hole. The purpose of firmly combining the toothbrush head and the combining rod can be achieved.
