It is fluted, it is equipped with rotating hub in groove, rotating hub is connected with supporter by bearing, and supporter is U-shaped structure, and the end of supporter
Limiting plate is equipped on the inside of mouthful, fixing bracket is extended, and support bracket fastened bottom is equipped in the top both sides of pedestal respectively inwards
Limited block.
Preferably, the structure of the brake bar is T fonts, and the short side of brake bar passes through pedestal, the long side position of brake bar
In the outside of pedestal.
Preferably, the bottom wall of the pedestal is equipped with circular groove, long straight through-hole is equipped in circular groove, and in through-hole
Brake bar is placed with, and the diameter of circular groove is more than the long edge lengths of brake bar.
Preferably, sliding rail on the side wall of the supporter is installed, fixed link is installed on the side wall of supporter, fixed link
Both ends are respectively placed in the sliding rail of both sides, and one end of fixed link passes through the side wall of supporter to extend to outside, and in fixed link
Equipped with handle.
Preferably, support plate is placed on the supporter, the side of support plate is hinged with movable pressing board, pacifies in support plate
Equipped with second spring, the bottom of movable pressing board is fixed in the one end of second spring far from support plate, and hairbrush is placed in support plate
Item is placed with fixed link on hairbrush item.
Preferably, there are gaps between the limited block and limiting plate.
Preferably, the bottom wall of the limiting plate is equipped with rubber pad.
The beneficial effects of the invention are as follows：
When the 1st, needing replacing hairbrush, it is straight to be turned to the length set in circular groove by rolling brake bar for the long side of brake bar
In through-hole, supporter then is pressed from front, supporter acts on the first spring, and supporter moves downward, and will be put by rotating hub
Rack goes to vacancy, so that the space of more Brusher being able to change bristles item becomes larger.
2nd, old hairbrush item is split away, can be by mobile fixed link, by fixed link scraping on sliding rail, can be with
Further chalk dust is removed.
3rd, new hairbrush item is positioned in support plate, is moved on hairbrush item by fixed link, fixed link movement
To movable pressing board, movable pressing board is pressed downwards, hairbrush item is fixed on to the lower section of fixed link, simultaneously because second spring is returned
Multiple effect, can up lift hairbrush item, and fixed link is by the position-limiting action of limiting plate, can be to hairbrush row replacement plus-pressure, in this way
Both sides simultaneously act on hairbrush item, it is ensured that it is firm, finally rotates entire supporter, is put into bottom plate, entirely
Replacement process finishes, and the present invention realizes the easy to change of hairbrush item, while of low cost by structure, and being convenient to teaching makes
With.
