Description

The adjustable cleaning brush of a kind of thickness

technical field

The utility model relates to household cleaning and uses the object field, particularly the adjustable cleaning brush of a kind of thickness.

Background technology

When cleaning, usually run into some gap grooves, now due to narrow space, common cleaning brush is difficult to stretch into, will cause corner or spot as yet untouched by a clean-up campaign like this.If these corner or spot as yet untouched by a clean-up campaign are not cleared up for a long time, can cause very large hygienic issues, therefore need the adjustable cleaning brush of a kind of thickness, the thicker cleaning brush of every day use carries out normal cleaning, when needs are cleared up the health in narrow and small gap, can rotate brush holder and use thinner cleaning brush to be cleared up small space.

The utility model content

For above problem, the utility model is the adjustable cleaning brush of a kind of thickness, the thicker cleaning brush of every day use carries out normal cleaning as required, when needs are cleared up the health in narrow and small gap, can rotate brush holder uses thinner cleaning brush to be cleared up small space, for reaching this purpose, the utility model provides a kind of thickness adjustable cleaning brush, comprise brush holder, shell and inner casing, described brush holder one end is link, one ring annular groove is arranged on described link, there is protuberance described outer casing underpart inboard, described shell is installed on outside the link cannelure by the bottom protuberance, there is outer bristle described shell front end and side, link one end has connector, described inner casing is threaded connection mode and is arranged on connector, there is groove described inner casing end, in described inner casing end grooves, inboard bristle is arranged, described inner casing front end has outer bristle.

As further improvement of the utility model, there is the spacing groove described shell inboard, and there is distance screws in the described inner casing outside, described distance screws is stuck in the spacing groove, distance screws moves along the spacing groove, by spacing groove and distance screws combination, can limit the distance of stretch out and draw back of inner casing.

As further improvement of the utility model, there are 3 strip projections in the described inner casing outside, there is corresponding strip groove described shell inboard, and described inner casing is installed in the shell strip groove by strip projected parts, by strip projected parts and strip groove, matches and can make shell relative static when inner casing rotates.

The utility model is the adjustable cleaning brush of a kind of thickness, mainly by outer, inner casing, formed, when needs are cleared up the health in narrow and small gap, can rotate brush holder, the inner casing opposite shell be revolved and stretch out, because the diameter of inner casing is little, there is bristle its head and side, now cleaning brush attenuates, and therefore can extend into and be difficult to, in clean close gap, be cleared up.Inhour rotation brush holder again after clean, treat that inner casing is retracted in shell, and the cleaning brush chap, carry out normal cleaning.
