Abstract
A telescopic ground writing pen relates to a special ground writing pen with a telescopic penholder. The telescopic ground writing pen comprises an upper pull rod, a lower pull rod, a pen point, a connecting piece, and an elastic body, wherein the connecting piece is fixed at the other end of the lower pull rod, is provided with a groove and matched with the inner diameter of the upper pull rod; and the elastic body is positioned at the outer edge of the connecting piece and is provided with an opening. The lower pull rod is rotated to lead the groove on the connecting piece and the opening on the elastic body to be positioned on a same straight line; the lower pull rod is further pushed upwards, so that air inside the upper pull rod can be discharged to the outside atmosphere along the groove on the connecting piece and the opening on the elastic body; or the lower pull rod is further pulled downwards. Air is sucked into the upper pull rod from the outside atmosphere so as to adjust the length of the penholder, thus being beneficial to writing. After the writing is finished, the ground writing pen can become a short bar convenient for carrying or a crutch favorable for people to walk. The ground writing pen can be repeatedly used, thus saving manpower and resources.
Description
Technical field
The utility model relates to writing implement, specially refers to the pen of book exclusively that penholder can stretch.
Background technology
Before the utility model proposes, along with the sustainable development of economic civilization, people, particularly the elderly like being engaged in various stress-relieving activities in the park, forge white silk near the greenery patches.Also have many people to like practicing calligraphy, they utilize branch to write on the ground, have perhaps bundled the sponge nib with wooden stick, bamboo pole, write on the ground and handwriting practicing after having dipped in water.These instruments are often all write with facility, so extremely simple and crude.The connection of nib is also very insecure, let alone with adjusting the requirement that penholder length satisfies handwriting practicing.In addition, these instruments are then abandoned it with after crossing, and select new apparatus again during next handwriting practicing, have both expended manpower, have also wasted resource.
The utility model content
The technical problems to be solved in the utility model is to overcome deficiency of the prior art, proposes a kind of ground book pen that can regulate penholder length arbitrarily, both can satisfy when writing the requirement highly that holds a pen; And nib firmly is connected with penholder, and people needn't worry in writing process written coming off; Ground book pen can use repeatedly, has saved manually, has saved resource.
The utility model is to realize by following technical measures.A kind of telescopic ground book pen comprises upper connecting rod; Insert the lower link of upper connecting rod; Be connected the nib of an end of described lower link; Be fixed on the connector that has groove and match of the other end of described lower link with the internal diameter of upper connecting rod; Be positioned at the elastomer with opening of described connector outer rim.
The middle part of described connector is the cylinder that matches with described elastomer.
At described cylinder root, on the position relative spacing square is arranged with the groove of connector.
Described elastomeric end face has the arc gap that matches with described spacing square.
Described arc gap has 20 °～180 ° radian.
Described arc gap has 90 °～120 ° radian.
The connector of described lower link and described nib is a threaded connector.
The material of described nib is softness and absorbent material.
The outside of described nib that is connected an end of described lower link is a protective sleeve.
A kind of telescopic ground book pen comprises upper connecting rod; Can insert the lower link of upper connecting rod; End at described lower link is the nib made from softness and absorbent material, and written afterbody has screw thread, and is meshing with each other and becomes fastening being connected with screw thread on the lower link.The other end that sticks to described lower link is a connector, and described connector inserts upper connecting rod and matches with the internal diameter of upper connecting rod, and generally speaking, the external diameter of connector is a bit larger tham the internal diameter of upper connecting rod.The middle part of described connector is inside recessed cylinder, has groove on the described connector of described cylindrical both sides.Described cylindrical outer rim on described connector is the elastomer with opening.Described cylindrical root on described connector has a spacing square, and described elastomeric end face has an arc gap to match with described spacing square.Described arc gap has 20 °～180 ° radian, and best arc gap has 90 °～120 ° radian.
In use, described lower link is inserted described upper connecting rod simultaneously together with described connector that sticks to described lower link and the elastomer that is positioned at described connector outer rim.Rotate described lower link then, groove on the described connector and the opening on the described elastomer are on the same straight line.Further promote described lower link to the inside of described upper connecting rod, the air of described upper connecting rod inside will be discharged in the ambient atmosphere along the opening on groove on the described connector and the described elastomer.In case meeting, the length of penholder writes when requiring, as long as with angle of described lower link rotation, groove on the described connector just can not be on the same straight line with the opening on the described elastomer, even continue inwardly to promote described lower link, the air of described upper connecting rod inside can't be discharged in the ambient atmosphere, and the length of penholder just is fixed up thereupon.When writing when finishing, the described lower link of repeated rotation, groove and the opening on the described elastomer on the described connector are on the same straight line, the air of described upper connecting rod inside continues to be discharged in the ambient atmosphere, till the upper end of described connector and described upper connecting rod the inner are very approaching, at this moment writing pen becomes a stub, carries very convenient.
In addition, write finish and cleared up nib after, put protective sleeve in the nib outside, adopts above-mentioned method to write the length of pen with adjusting, ground is write and can be become the crutch that people walk again.
After the utility model adopted abovementioned technology, ground was write the penholder of pen and can highly be regulated according to user's custom, had satisfied when writing the requirement highly that holds a pen; Nib firmly is connected with penholder, and nib can not come off in the writing process; Write finish after, ground book pen can shorten stub into, carries easily, also can put protective sleeve in the nib outside becomes the crutch that people walk, ground book pen can use repeatedly, has saved manually, has saved resource.
