Claim:
A foldable toothbrush comprising: a shell being hollow and having a top opening; a front opening; a pivoting sidewall having an inner surface and an outer surface; a holding sidewall having an inner surface and an outer surface; and a holding segment being formed on the holding sidewall near the top opening; a cover being mounted pivotally to the pivoting sidewall of the shell, selectively covering the top opening of the shell and having a bottom surface; a distal side; and a holding segment being formed on the distal side and selectively engaging the holding segment of the shell; a mounting sleeve being hollow, being connected pivotally in the front opening of the shell and having a pivoting end; a distal end; and an outer wall; a handle being mounted in the distal end of the mounting sleeve, being selectively rotatable and slidable in the mounting sleeve and having a head; and multiple bristles being attached to the head of the handle; wherein the mounting sleeve has an inner sleeve being mounted pivotally in the front opening of the shell, being hollow and having an outer diameter; an inner diameter; a front end; an inner sidewall; and an elongated limiting recess being formed transversely in the inner sidewall of the inner sleeve; an outer sleeve being mounted securely around the inner sleeve, being hollow and having a rear passage being adjacent to the front end of the inner sleeve, communicating with the elongated limiting recess of the inner sleeve and having an inner diameter being larger than the inner diameter of the inner sleeve; a front passage communicating with the rear passage and having an inner sidewall and an inner diameter being smaller than the inner diameter of the rear passage; a limiting recess being formed transversely in the inner sidewall of the front passage of the outer sleeve, being adjacent to the rear passage and misaligning with the elongated limiting recess of the inner sleeve; and a shoulder being formed between the rear and front passages; wherein the handle has a mounting end; an outer wall; an actuating protrusion being formed on and protruding transversely out from the mounting end of the handle, selectively protruding into the limiting recess and the elongated limiting recess and selectively abutting the shoulder; and an elongated recess being formed transversely in the outer wall of the handle.
