Aiming at the problems in the prior art, the utility model provides a telescopic toothbrush, which has the following specific scheme:

the toothbrush comprises a toothbrush head, an upper section of a toothbrush handle, more than one section of middle section of the toothbrush handle and a tail section of the toothbrush handle, wherein the middle section of the toothbrush handle and the tail section of the toothbrush handle are both in a vertically through tubular shape;

the toothbrush handle comprises a toothbrush handle upper section, a toothbrush handle middle section and a toothbrush handle tail section, wherein the toothbrush handle upper section, the toothbrush handle middle section and the toothbrush handle tail section are of a structure with a narrow top and a wide bottom, inner cavities of the toothbrush handle middle section and the toothbrush handle tail section are also of a structure with a narrow top and a wide bottom, when the toothbrush is completely pulled out to the longest state, the lower end of the toothbrush handle upper section and the inner wall of the toothbrush handle middle section form interference fit, and the outer wall of the lower end of the toothbrush handle middle section and the inner wall of the toothbrush handle tail section form interference fit.

Preferably, the number of the middle sections of the toothbrush handle is one section.

Preferably, the lower end of the upper section of the toothbrush handle and the upper end of the middle section of the toothbrush handle are further prevented from being pulled out from the middle section of the toothbrush handle by a step limiting structure; similarly, the lower end of the middle section of the toothbrush handle and the upper end of the end section of the toothbrush handle are also prevented from being pulled out from the end section of the toothbrush handle through a step limiting structure.

Preferably, the toothbrush head is installed with the upper section of the toothbrush handle in an insertion manner.

Preferably, the retractable toothbrush further comprises a bottom cover for covering the lower port of the distal section of the toothbrush handle.

Preferably, the toothbrush head and the upper section of the toothbrush handle except the brushing part are just all positioned in the middle section of the toothbrush handle, and the middle section of the toothbrush handle is just all positioned in the tail section of the toothbrush handle, so that the highest expansion ratio is realized.

The telescopic toothbrush provided by the utility model has the following beneficial effects:

1. the structure is simple, the assembly is very convenient, the telescopic structure is telescopic, the occupied space is small, and the automatic vending machine is easy to place in;

2. adopt interference fit to guarantee the stable state when using for structural too much limit structure that does not need reduces the processing cost.

Detailed Description

The utility model is further described below with reference to the following figures and specific examples. The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", etc. are used in an orientation or positional relationship based on that shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example one

Referring to fig. 1 to 3, this embodiment provides a telescopic toothbrush, including toothbrush head 1, toothbrush handle upper segment 2, toothbrush handle interlude 3, toothbrush handle end segment 4 are upper and lower penetrating tubulose, toothbrush head 1 fixed mounting in the upper end of toothbrush handle upper segment 2, toothbrush handle upper segment 2 can be in the toothbrush handle interlude 3 downwards, toothbrush handle interlude 3 can be in the toothbrush handle end segment 4 downwards.
