Compared with the prior art, the present utility model has the following advantages:

1. 1. The brush handle and the brush head are detachably connected to each other, through the threaded connection portion a tightly rotating connection is performed, and by the elastic clamping buckle and the through hole of the clamping buckle locking is realized, thereby an axial sliding and a radial rotation are effectively prevented, thereby a convenience of disassembly and stability of use realized simultaneously.
2. 2. When firmly rotating connection and dismantling of the brush handle and the brush head only the pressing Entsperrvorsprung pressed, then the elastic clamp buckled into the discharge space of the brush handle, the fingers come with the connection point not in touch, so that the operation is safe and easy ,
3. 3. After tightly connecting the brush handle and the brush head, the brush handle and bristles make a certain angle to facilitate exertion of the force and thus improve the working efficiency of the dead zones.

Detailed embodiments

In the context of figures in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model are explained clearly and completely below. Obviously, the illustrated embodiments do not represent all embodiments, but only a part of the embodiments of the present utility model. All other embodiments obtained by one of ordinary skill in the art based on the embodiments herein without creative work should be considered to be within the scope of the present utility model.

embodiment

As shown in figures, the present embodiment discloses a detachable elbow brush comprising a brush handle 1 , a brush head 2 and bristles 3 , wherein at one end of the brush handle 1 a threaded connection section 6 is arranged, wherein at one to the threaded connection portion 6 adjacent side wall of the brush handle an elastic clamp buckle 4 is arranged, and being on the brush handle 1 Furthermore, a discharge space for the radial deformation of the elastic clamp buckle 4 is provided; and wherein inside the brush head 2 an open receiving chamber 7 is provided, and wherein in the open receiving chamber 7 a threaded connection section 6 is arranged, and wherein on a side wall of the open receiving chamber 7 a through hole of the clamp buckle 8th is provided;
the brush handle 1 is through its threaded connection section 6 removable to the inside of the open receiving chamber 7 connected, wherein during the firmly rotating entry of the brush handle 1 in the open receiving chamber 7 the elastic clamp buckle 4 in the through hole of the clamp buckle 8th is clamped; at this time, the relative positions are in the axial and radial directions of the brush handle 1 and the brush head each firmly locked to ensure the stability of the use of the brush.

On a side wall of the brush handle 1 is still a pressing Entsperrvorsprung 5 arranged, wherein the pressing Entsperrvorsprung 5 with the elastic clamp buckle 4 is integrally connected, and wherein the pressing Entsperrvorsprung 5 and the elastic clamp buckle 4 along the axial direction of the brush handle 1 arranged one behind the other. When pressing the pressing unlocking projection 5 it can be fed into the relief room, now becomes the flexible tab 4 subsequently retracted into the relief space to unlock the brush handle 1 and the brush head 2 complete, there is a simple operation, and a replacement of the brush handle 1 or the brush head 2 can be realized quickly.
