A trundle device comprises a trundle unit, an assembly unit and a brake unit. The trundle unit comprises a trundle seat group, a trundle group pivoted to the bottom of the trundle seat group, and a protection seat group positioned in the trundle seat group and located between the trundle seat group and the trundle group. And the assembling unit is arranged on the wheel seat group and is suitable for being inserted and assembled in the foot tube. And the brake unit is inserted into the assembling unit, the wheel seat group and the protective seat group, and can move up and down relative to the assembling unit and the wheel seat group so as to be switched between a brake position and a preparation position. And at the brake position, the brake unit downwards protrudes out of the protective seat group and is propped against the trundle group so as to prevent the trundle group from rolling. And at the preparation position, at least one part of the brake unit retracts into the protection seat group and is separated from the trundle group. The hair brush has the characteristic that foreign matters such as hair are not easy to accumulate and clamp.
