a connecting structure of a brush handle and a brush head comprises the brush head and the brush handle which are mutually connected, the brush head or the brush handle is arranged as a first connecting piece, the brush handle or the brush head is arranged as a second connecting piece, the first end of the first connecting piece is connected with the first end of the second connecting piece, the first section of the first connecting piece, which is close to the first end, is provided with an axial first blind hole, a first section of the second connecting piece close to the first end is provided with an axial second blind hole, the hole wall of the first section of the first connecting piece is provided with a radial buckling through hole, the hole wall of the first section of the second connecting piece is provided with a radially through U-shaped groove, an elastic sheet is formed in the U-shaped groove, a convex column is arranged on the end head of the elastic sheet, the first section of the second connecting piece is arranged in the first blind hole of the first connecting piece, and the convex column is arranged in the buckle through hole; the opening direction of the U-shaped groove is far away from the first end of the second connecting piece; the guide strip is axially and outwards protruded on the hole wall of the first blind hole of the first connecting piece, the guide groove which is axially and inwards concave is formed in the outer wall of the first section of the second connecting piece, and the guide strip is arranged in the guide groove.
Preferably, in order to enable the first end of the second connecting piece to enter the first end of the first connecting piece more smoothly and quickly, the distance between the end head, close to the first end of the first connecting piece, of the guide strip and the first end of the first connecting piece is 1-20mm, and one end of the guide groove is flush with the first end of the second connecting piece.
Preferably, in order to facilitate connection with other components, the second section of the second connecting member near the second end is provided with a blind mounting hole which is axial and used for connection with other components. The other component is generally a bristle holder for holding bristles, and the bristle holder is provided with a joint connected with the brush head.
Preferably, in order to connect the first connecting member and the second connecting member more smoothly, the circumferential outer wall of the first connecting member and the circumferential hole wall of the first blind hole thereof, and the circumferential outer wall of the second connecting member and the circumferential hole wall of the second blind hole thereof have a taper of 1-10 °, the first end diameter of the first connecting member is larger than the second end, and the first end diameter of the second connecting member is smaller than the second end.
Preferably, in order to adapt to the use habit of people, the brush handle is a first connecting piece, and the brush head is a second connecting piece.
The beneficial effects of the utility model reside in that:
the utility model changes the opening direction of the U-shaped groove, so that the first connecting piece and the second connecting piece are more smooth when being mutually inserted and connected, and the stability is better after the connection; through set up the gib block on first connecting piece, set up the guide way on the second connecting piece, not only do benefit to accurate direction, improve connection efficiency, guarantee moreover after connecting that can not relative rotation between first connecting piece and the second connecting piece, avoided first connecting piece and second connecting piece because of the problem that relative rotation breaks away from.
