Accompanying drawing explanation

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is another kind of structural representation;

Fig. 3 is the use state diagram of Fig. 1.

The specific embodiment

As shown in Figure 1, this novel ball-point pen comprises by montant 11 and is screwed onto the penholder 1 that the nut 12 on montant 11 forms, and in penholder 1, be set with pen core 2, the top slide of montant 11 is connected with the cap for brush 15 that is sleeved on pen core 2 and stretches out montant 11.The back-moving spring 7 being sleeved on pen core 2 is installed in penholder 1, the low fastening station 13 of stretching in being equipped with on the inwall of nut 12, the bottom of pen core 2 is equipped with the top fastening station 14 of evagination, and back-moving spring 7 is arranged between low fastening station.The top of pen core 2 is provided with the card base 3 that stretches out obliquely montant 11, and the sidepiece of montant 11 is provided with the upper fixing hole corresponding with card base 35 and is positioned at the lower fixed hole 6 of upper fixing hole 5 belows.Distance between upper lower fixed hole equals the length that nut 12 is stretched out in pen core 2 tips.

The mounting means of card base 3 has multiple, as shown in Figure 1 a kind of embodiment: card base 3 is fixed on the collar 8, and the collar 8 clamps or is sleeved on pen core 2, and the end of card base 3 is provided with the fixture block 9 that stretches out locating hole 5.The second embodiment as shown in Figure 2: card base 3 is one-body molded with pen core 2, and the end of card base 3 is provided with the fixture block 9 that stretches out locating hole 5.In two kinds of embodiment, fixture block 9 is right-angled trapezium, the inner surface of fixture block 9 is than its appearance face length, the long limit and the card base 3 that are right-angled trapezium two parallel edges are affixed, the upper surface of fixture block 9 is parallel with the roof of upper fixing hole 5, the lower surface of fixture block 9 is inclined-plane, and the angle between the lower surface of fixture block 9 and upper fixing hole 5 diapires is acute angle.Montant 11 is provided with pen clip 4 corresponding with upper lower fixed hole, that can make card base 3 reset, and inner surface, the position corresponding with lower fixed hole 6 of pen clip 4 are provided with jacking block 10, between pen clip 4 and montant 11, are also provided with reinforcement, make pen clip 4 more firm.Pen clip 4 can also facilitate depositing of penholder 1.

The utility model is to use like this: as shown in figures 1 and 3 with hand by the cap for brush 15, pen core 2 is moved down, now pen core 2 drives card base 3 to move down, after departing from upper fixing hole 5, fixture block 9 on card base 3 power that is squeezed also moves down with pen core 2, in the time that fixture block 9 arrives lower fixed hole 6, extruding force disappears, and fixture block 9 is stuck in lower fixed hole 6, and back-moving spring 7 is in compressive state, now nut 12 is stretched out in the tip of pen core 2, can write; After use finishes, extruding pen clip 4, make the jacking block 10 of pen clip 4 inner sides push fixture block 9, make fixture block 9 depart from lower fixed hole 6, now back-moving spring 7 resets, its elastic band is started writing on core 2 and is moved, when fixture block 9 is squeezed power also with on move, in the time moving on to upper fixing hole 5 place on fixture block 9, extruding force disappear, thereby snap fit onto in fixing hole 5, now pen core 2 is retracted in nut 12.In use procedure, back-moving spring 7 also has the effect of guiding, can guarantee that pen core 2 straight lines move up and down, and avoid writing unsettled phenomenon.

The utility model is not limited to the above-mentioned specific embodiment, and those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
