The content of the invention
The purpose of this utility model is to provide a kind of blackboard writing chalk clamp device, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of blackboard writing chalk clamp device, including
Apparatus main body, described device body side slide and are provided with push handle, and described device main body opposite side is fixedly installed fingerstall, described
Cavity is offered in apparatus main body, chalk is provided with the cavity, described device body front part is fixedly installed dust block board, institute
The front end for stating apparatus main body is provided with collet chuck, and the collet chuck coordinates with the chalk, spiral shell outside the collet chuck
Tapered cup nut is connected to, the rear end of described device main body is provided with link, and the push handle is connected by sliding block with bottom plate, the sliding block
Coordinate with the slide that described device body side opens up.
Preferably, the bottom plate offsets with described chalk one end.
Preferably, described device body side is provided with connecting seat, and the fingerstall is arranged on the connecting seat.
Preferably, car has screw thread outside the collet chuck, and the screw thread is adapted to the tapered cup nut.
Compared with prior art, the beneficial effects of the utility model are：The blackboard writing chalk clamp device is in use, teacher
Can be by tapered cup nut outward turning so that collet chuck loses the extruding force of tapered cup nut and opened, at this moment by chalk from collet chuck
Place is inserted into the cavity in apparatus main body, and after chalk touches base, teacher can adjust chalk from collet chuck by push handle
The length that end is stretched out, after length adjustment satisfaction, then teacher is by tapered cup nut inward turning so that tapered cup nut is thicker to collet chuck
One end movement so that collet chuck is compacted contraction, and at this moment chalk is clamped and immovable, and teacher can hand-held electronic device main body
Write, during writing, forefinger or middle finger can be inserted into fingerstall by teacher, and fingerstall plays good fixation supporting role, makes
It is more comfortable when being affectedly bashful apparatus main body to obtain teacher, link can be used for hanging up the present apparatus, and dust block board can prevent that chalk dust is direct
Fly to the facial direction of teacher, under the barrier effect of dust block board, chalk dust has most to be all blocked and fall, be not easy by
Teacher sucks, and is advantageous to the health of teacher；The present apparatus is simple in construction, easy to operate, teacher can be avoided to be write on blackboard
Finger contacts with chalk and causes body skin uncomfortable phenomenon occur for a long time during content, protects the hand skin of teacher, while conveniently
Carry, have and keep off grey effect.
