The content of the invention
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of chalk sharpener, to solve above-mentioned technology
Problem.The utility model chalk sharpener is simple in construction, in that context it may be convenient to by chalk sharpener point, and can be by the chalk chipped away
Consider centralized collection to be worth doing, it is not only environmentally friendly but also hygienic.
The technical solution of the utility model is：Chalk sharpener, including sharpener body, the sharpener body are provided with
Some insert grooves, mother of the insert groove along the circular cone are uniformly provided with conical chalk hole, the hole wall in the chalk hole
Line is set, and blade is provided with the insert groove, and the knife back of the blade is located in the insert groove, one end of the blade with
The insert groove is hinged, and the screw at the angle of inclination of the regulation blade of other end connection one of the blade, the screw is worn
The screw hole being located on described this body sidewall of sharpener is crossed, the sharpener body bottom portion is provided with discharging opening, in the sharpener
Body bottom portion is used to collect the Integrated Chip cylinder that chalk is considered to be worth doing provided with one, is connected between the Integrated Chip cylinder and the sharpener body by screw thread
Connect.
Preferably, the adjustable range at the angle of inclination of the blade is 25-35 degree.Chalk can be whittled into different thicknesses
Degree.
Preferably, the inwall of the Integrated Chip cylinder is provided with internal thread, and the sharpener body bottom portion outer wall is provided with and institute
State the external screw thread of screw-internal thread fit.Sharpener body is connected by screw thread with Integrated Chip cylinder.
Preferably, the diameter of the Integrated Chip cylinder is more than the diameter of the sharpener, and the Integrated Chip cylinder bottom is a horizontal base
Seat, the Integrated Chip cylinder is made up of transparent material.Integrated Chip cylinder selects transparent material, in that context it may be convenient to the internal chalk bits of Integrated Chip cylinder seen
Collecting amount, easy cleaning.
Preferably, the tapping in the chalk hole is provided with a dismountable lid, the lid and sharpener top
It is connected through a screw thread.Chalk port lid is lived by lid when without using chalk sharpener, blade scratch can be prevented.
The beneficial effects of the utility model are：
1. the utility model chalk sharpener is simple in construction, in that context it may be convenient to which chalk is fined away.
2. chalk, can be whittled into different thickness journeys by the tilt adjustable section of the blade of the utility model chalk sharpener
Degree.
3. the utility model can consider the chalk chipped away to be worth doing centralized collection, not only environmentally friendly but also hygienic.
