Description

Folding toothbrush with bidirectional limiting protective structure Technical Field The utility model relates to the technical field of toiletries, in particular to a folding toothbrush with a bidirectional limiting protection structure. Background The folding toothbrush is a toothbrush with a foldable handle. The existing folding toothbrush comprises a front handle and a rear handle, bristles are arranged on the front handle, the rear handle can be folded or unfolded in a rotating mode relative to the front handle, the rear handle is in a use state when unfolded, and the rear handle is in a storage state when folded. Because the rear handle can rotate relative to the front handle, the rear handle is easy to be closed (folded) by mistake during use in the unfolded state or easy to be opened (unfolded) by mistake during storage in the folded state. Disclosure of utility model The utility model aims to provide a folding toothbrush with a bidirectional limiting protective structure, so as to solve the problems of unstable unfolding state and unstable folding state of the existing folding toothbrush. The utility model is realized by the following technical scheme: The utility model provides a folding toothbrush with two-way spacing protective structure, includes front handle and back handle, the front handle with be equipped with on one of them of back handle and rotate the pivot of being connected with the other, the back handle is around the pivot axis is relative the front handle rotates folding or expansion, back handle periphery side is protruding to be equipped with folding damping piece and expansion damping piece, folding damping piece with expansion damping piece is the circular arc lug, expansion damping piece with the pivot eccentric setting, expansion damping piece when the back handle expand with the front handle offset restriction back handle rotates towards folding direction, folding damping piece with the pivot eccentric setting, folding damping piece when the back handle is folding with the front handle offset restriction back handle rotates towards expansion direction.
