The pressing type telescopic pen is characterized in that a drive rod and a driven rod are arranged in the upper penholder and the middle penholder, one end ofthe drive rod is fixedly connected with the upper penholder and the pen clamp, the other end of the drive rod is provided with saw teeth which are arranged in a ring shape, and drive rod lugs which are arranged in the ring shape at intervals are arranged on the inner side wall of the drive rod; one end of the driven rod is provided with a boss, saw teeth which are matched with the drive rod are arranged on the inner side surface of the boss, positioning steps are arranged on the side wall of the boss, and driven rod lugs which are arranged in the ring shape at intervals are arranged at the other end of the driven rod; a spring is arranged between the end part of the driven rod and the pen clamp; and grooves which are matched with the positioning steps on the driven rod and circumferentially arranged are arranged in the middle penholder, and the driven rod is movably connected with the middle penholder through the positioning steps and the grooves.
Description
Technical field
The invention belongs to flexible pen device field, especially a kind of pressing type telescopic pen.Should flexible pen regain in the non-nib of writing under the state, a body is retractable into short body, and behind pressing type telescopic, nib is stretched out, and a body elongation is fit to the not consumer's of homochirality, all ages and classes use very much.
Background technology
Existing pressing type telescopic formula pen is to finish telescopic action in penholder inside by increasing special-shaped slide rail and steel ball, structure is very complicated, assembling is very difficult during production and assembly, because steel ball and plastics slide rail Long contact time, break-in, thereby be easy to cause the wearing and tearing of plastics slide rail to cause flexible having some setbacks.
In addition, a body of existing pressing type telescopic pen cannot freely stretch, so handwriting or oversize or too short, oversizely then carries and preserve inconvenience, and is too short hand-held inconvenient when then writing.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy to assembly, quick, the pressing type telescopic pen smoothly forever that wear problem can not appear in parts, can guarantee to stretch.
Technical scheme of the present invention is: pressing type telescopic pen, comprise pen clip, last penholder, middle penholder, following penholder, nib, nib, time penholder, middle penholder, last penholder are linked in sequence, it is characterized in that being provided with drive rod (being fixed wheel) and follower lever (being driving wheel) at last penholder and middle penholder inside, be provided with the pencil lead passage in drive rod and the follower lever, one end of drive rod is fixedlyed connected with pen clip with last penholder, the other end at drive rod is provided with the sawtooth that goes in ring and distribute, and the madial wall of drive rod is provided with the drive rod projection that annular space distributes; One end of follower lever is provided with boss, and the sawtooth that is complementary with drive rod is set on the medial surface of described boss, and the sidewall of described boss is provided with positioning convex, and the other end is provided with the follower lever projection that annular space distributes; Follower lever and drive rod connect together by drive rod projection and follower lever projection, and the drive rod sawtooth touches mutually with the follower lever sawtooth is staggered, is provided with spring between follower lever end and pen clip; The inside of middle penholder have with follower lever on the groove of the circle distribution that is complementary of positioning step, follower lever is moving to flexibly connect by positioning convex and groove with middle penholder, the top of middle penholder inner groovy is provided with the inclined-plane, is provided with spring between nib and middle penholder.
The inner side end of penholder is the inclined-plane in described.
Effect of the present invention is: pressing type telescopic pen, be provided with drive rod and follower lever at last penholder and middle penholder inside, be provided with the pencil lead passage in drive rod and the follower lever, one end of drive rod is fixedlyed connected with pen clip with last penholder, follower lever and drive rod connect together by drive rod projection and follower lever projection, the drive rod sawtooth touches mutually with the follower lever sawtooth is staggered, is provided with spring between follower lever end and pen clip; The inside of middle penholder have with follower lever on the groove of the circle distribution that is complementary of positioning step, follower lever is moving to flexibly connect by positioning convex and groove with middle penholder.
The present invention is on the basis of existing common pressing tool, between plastics drive rod and plastics follower lever, increase the projection hook that cooperatively interacts, had simple in structure, easy to assembly, characteristics efficiently, wearing and tearing can not appear in parts, and what can guarantee to stretch is forever smooth and easy.
The present invention is described further below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of penholder among Fig. 1;
Fig. 3 is the structural representation of drive rod and follower lever among Fig. 1.
The specific embodiment
Among Fig. 1, pressing type telescopic pen comprises pen clip 1, goes up penholder 2, middle penholder 3, penholder 4, nib 5 down, nib 5, down penholder 4, middle penholder 3, go up penholder 2 and be linked in sequence, following penholder 4 is provided with holds glue 6.Be provided with drive rod 7 and follower lever 8 at last penholder 2 with middle penholder 3 inside, be provided with the pencil lead passage in drive rod 7 and the follower lever 8, one end of drive rod 7 is fixedlyed connected with pen clip 1 with last penholder 2, between follower lever 8 ends and pen clip 1, be provided with spring 14, the other end at drive rod 7 is provided with the sawtooth that goes in ring and distribute, and the madial wall of drive rod 7 is provided with the drive rod projection 9 that annular space distributes; One end of follower lever 8 is provided with boss 10, and the sawtooth 11 that is complementary with drive rod is set on the medial surface of boss 10, and the sidewall of boss 10 is provided with positioning convex 12, and the other end is provided with the follower lever projection 13 that annular space distributes; Follower lever 8 and drive rod 7 connect together by drive rod projection and follower lever projection, drive rod sawtooth and staggered touch mutually (referring to the Fig. 3) of follower lever sawtooth.The inside of middle penholder 3 have with follower lever on the groove 15 of the circle distribution that is complementary of positioning convex, follower lever moving 8 flexibly connects by positioning step and groove with middle penholder, the top of middle penholder 3 inner groovies is provided with inclined-plane 16, and the inner side end of middle penholder 3 is inclined-plane 17.(referring to Fig. 2) is provided with spring between nib 5 and middle penholder 3.
Operation principle of the present invention is: cooperate the angle that reaches middle penholder inside groove top by the sawtooth on drive rod, the follower lever, can be whenever once by last penholder, and the driving wheel tooth will rotate to an angle, and once press thereby form.Because the difference of middle penholder inside groove height is pressed 2 continuously and will be formed a knockout of pen core and the circulation of the core that contracts.
The tail end of follower lever has projection, and also there is projection drive rod inside, and when penholder was not flexible, the projection of drive rod will tangle mutually with the projection of follower lever inside.When pressing penholder, follower lever rotates to an angle, and the projection that this moment, follower lever was taken turns rotates to an angle and can avoid the projection of drive rod inside, and under the elastic force effect of spring, drive rod will move thereby formed elongation along moving on the penholder direction.Otherwise when pressing once more, the projection of follower lever will be linked up with the projection formation of drive rod inside once more, and penholder and pen clip just can shrink on this moment.
