Description

Chalk self-sharpening and dust collection environmental protection pen

The utility model relates to a kind of writing implement and a kind of chalk of chalk, the novel environment friendly pen and the novel chalk of especially a kind of energy automatic charging, self-sharpening and dust collection.

At present, known chalk two ends differ in size, writing of it wanted armrest to hold chalk to go to write, after having write, making the people expire hand is chalk dust, and What is more, chalk dust dyes on people's the head, face, clothes, thereby Writer's image caused certain infringement, and so both unhygienic, very easily the writer is gone down with again.In addition, because Hand writing, chalk is very easily fractureed, and many chalk heads are not used, and the writer is dyed dirty finger with a large amount of water flushings by chalk dust in addition, causes resource and waste of time.Moreover, when the writer will write very little word or paint the very thin figure of stroke, usually firmly the chalk head is gone to write again after levigate on the blackboard, make chalk dust waft in the chamber, both contaminated environment was lost time again and energy.In a word, above ways of writing, both unhygienic, contaminated environment again; Both inconvenient, cause the wasting of resources again; The energy of both having lost time, the physical and mental health to the people works the mischief again.

Order of the present utility model provides a kind of novel chalk and lettering pen thereof, it not only can protect the people hand, face, etc. the position be not subjected to being infected with of chalk dust, and can automatic charging, chalk one end of fining away is automatically stored chalk dust get off.Like this, not only hygienic and convenient, and energy-conserving and environment-protective; Not only save time energy and guarantor's physical and mental health.

The purpose of this utility model is achieved in that the chalk that at first designs big and even thickness such as a kind of two ends; Secondly in an outer gram of plastics that resembles pen, the cap for brush is connected with pencil sharpener, designs one and store the dirt storehouse in pen emits, a storage of design dirt Cang Gai directly over the pencil sharpener outside the cap for brush, storage dirt storehouse covers hook of design, and storage dirt Cang Gai is connected with the cap for brush, and hook is connected with storage dirt Cang Gai; Pole is connected with the cap for brush, cracking of design and than restraining longer other end barrel with cover outside the pole, barrel designs spring all over the body in a pole, and spring clip is in a pole shell and barrel, and like this, barrel is connected with a pole shell.When people need write chalk, open the lid of tail behind the barrel, the chalk of packing into is built lid, and with defeating the barrel afterbody, chalk one end just comes out from the barrel head end automatically, abandons pressure then, and chalk will be clamped by the apparatus for breaking of barrel head end firmly.After having write the chalk that has exposed as people, repeat above operation, till having write chalk.When people need chalk one end to fine away, press the barrel tail end earlier, the length that allows chalk expose to want, then the pencil sharpener in the cap for brush is enclosed within on the chalk, firmly rotate the cap for brush, chalk will be sharpened, and chalk dust falls in the storage dirt storehouse, after the dust in the storehouse is full, opens storage dirt Cang Gai and outwell chalk dust.At last, take down the cap for brush, just can write.Pass through aforesaid operations, avoided staff directly contacted, avoided with chalk chalk dust pollution, avoided chalk to be fractureed, avoided to have reached raising chalk utilization ratio, energy-conserving and environment-protective, hygienic and convenient and the able-bodied purpose of assurance writer because of need chalk taper makes the people take great energy effort, wards off unnecessary trouble such as exempted to wash one's hands.

Owing to take such scheme, can be when chalk be write, ward off and exempt from chalk and be infected with Writer's, can improve chalk and utilize degree, can carry out environmental protection, can guarantee Writer's physical and mental health.This use new function is numerous, and is simple in structure, easy to carry.
