Stating fixed link can rotate in the movable chamber by axis of connecting rod.
Further, the movable chamber includes arc inner wall, and the inner wall is equipped with locating piece, the end of the fixed link
It is formed with and the matched locating slot of the locating piece.
Further, the locating piece is formed as hemispherical projections, and the locating slot is formed as hemispherical depression.
Further, the diameter of the fixed link is greater than the diameter of the notch of the locating slot, the end of the fixed link
Be formed as towards the inclined inclined-plane of the notch.
Further, the movable chamber is formed as 90 ° of sector.
Further, the surface of the slot is equipped with flexible rubber, and the connecting rod and the slot are interference fitted.
Further, the peripheral side of the brush head is equipped with the rubber for facilitating rotation brush head.
The utility model has the beneficial effects that: being arranged by the way that fixed link is arranged in the connecting rod of brush handle, and in brush head
Corresponding movable chamber, after so that connecting rod is fully inserted into the slot of brush head, fixed link can rotate in movable chamber, then pass through movable chamber
The locating slot of locating piece and fixed link on inner wall cooperates, and realizes that brush head is bonded with brush handle, clever structure, connection side
Just, it can effectively prevent brush head to loosen because of high-frequency vibration.
