The specific embodiment

Below in conjunction with drawings and Examples, the present invention is further described:

Embodiment mono-:

In the embodiment mono-shown in Fig. 1, Fig. 2, this rotary tooth-brush comprises brush body 1, and brush body 1 front end is head toothbrushes 10; Described head toothbrushes surface is provided with fasten bristles 6, and described fasten bristles 6 is surrounded a spill spin block 400, on described spill spin block 400, is also provided with bristle; Described spill spin block 400 is driven by the gear mechanism of brush body inside, described gear mechanism is engaged in a toothed rack 21, described tooth bar 21 is connected to one can be at the slide block 2 of described brush body 1 inner longitudinal sliding motion, this slide block 2 is laterally outward extended with the grip part 22 that can be gripped by palm, and stretch out outside brush body 1 through the chute (not shown) that is opened in described brush body sidewall described grip part 22; Described slide block 2 is connected by back-moving spring 5 with the terminus inner of brush body 1.

In embodiment mono-, described gear mechanism comprises a gear wheel 3 meshing with described tooth bar 21, and a pinion 4 meshing with this gear wheel 3, and described pinion 4 coaxially joins with described spill spin block 400; When gear wheel 3 turns over the less number of degrees, pinion 4 just can turn over the more number of degrees.
