Detailed description of the invention

The defect that element is many, cost is high existing in order to overcome the pen core position adjusting mechanism of existing ball pen, the present embodiment provides a kind of ball pen cutting ferrule shown in a kind of Fig. 1,2, comprise the hollow cylinder 1 for being fastened in pen core top, also comprise the retaining sheet 2 that a top is connected with described hollow cylinder 1 top, in the bottom outer surface of this retaining sheet 2, be provided with at least one projection 3, the end face of this projection 3 connects a contact pressing piece 5 by a connecting rod 4.Retaining sheet 2 Main Functions are here to realize connecting of ball pen cutting ferrule and pen container, realization is spacing to ball pen cutting ferrule, therefore this retaining sheet 2 requires to have certain consistency and elasticity, generally choose plastics, duroplasts, certainly, also can choose the metal material such as iron plate or aluminium flake.

In order to strengthen the power that holds between retaining sheet 2 and pen container, the present embodiment spy is provided with U-shaped shell fragment 6 between hollow cylinder 1 and retaining sheet 2, this U-shaped shell fragment 6 is opening down, the lower end of its left and right shell fragment 7,8 presses respectively the bottom with retaining sheet 2 at hollow cylinder 1, strengthen thus the thrust between retaining sheet 2 and pen container, guaranteed the steadiness of ball pen cutting ferrule location.

And in order to prevent that U-shaped shell fragment 6 is shifted, the present embodiment spy is provided with longitudinal spacing groove in hollow cylinder 1 and retaining sheet 2 and left and right shell fragment 7,8 contact positions, on the inner surface of the connecting portion of hollow cylinder 1 and retaining sheet 2, is provided with the transverse concave groove spacing to the top of U-shaped shell fragment 6.Thereby guarantee the steadiness of the position of U-shaped shell fragment 6, guaranteed practical stability.

In conjunction with Fig. 3, be not difficult to find out, the projection 3 relating in the present embodiment is can be specifically column, arc or triangle, here preferably cylinder as projection 3.

Fig. 4,5 is depicted as a kind of ball pen pen container that contains above-mentioned ball pen cutting ferrule, comprises cylindrical shell 9, and ball pen cutting ferrule is set in the top of cylindrical shell 9; The top side wall of cylindrical shell 9 offer two be longitudinally arranged in order use upper limit hole 11, the lower limit hole 12 of stretching out for projection 3, connecting rod 4 and contact pressing piece 5 and the chute 13 that is communicated with this upper limit hole 11 and lower limit hole 12, the opening of this chute 13 is greater than the thickness of connecting rod 4; The height of projection 3 equals the longitudinal opening size in upper limit hole 11, lower limit hole 12, it is the distance (seeing Fig. 6,7) between upper shed and the under shed in upper limit hole 11, lower limit hole 12, so that well realize spacing to projection 3, guarantee that it smoothly, stretch out completely in upper limit hole 11, lower limit hole 12.

The sidewall of the cylindrical shell 9 at upper limit hole 11, lower limit hole 12 and chute 13 places is flat face 14, can reduce like this collision that non-artificial factor occurs, and makes the position of projection 3 change and then change the position of pen core.

As seen from Figure 5, ball pen pen container also comprises the clamp 15 that top is connected with the top of cylindrical shell 9, and described flat face 12 is just right with this clamp 15.

And for the ease of the dismounting of ball pen cutting ferrule, spy is provided with the portion of being affectedly bashful 10 shown in Fig. 1,2,3 or 4 at hollow cylinder 1 top, thus, contact pressing piece 5, connecting rod 4 and projection 3 being advanced after cylindrical shell 9, upwards push in the process of whole ball pen cutting ferrule, being affectedly bashful portion 10 first can stretch out from the top of cylindrical shell 9, at this moment, pinch the outside drawing of the portion of being affectedly bashful 10 with hand, can easily ball pen cutting ferrule be taken out.

It should be noted that the connecting portion between retaining sheet 2 and hollow cylinder 1 can be the arcwall face shown in Fig. 2, can be also the rectangular surfaces shown in Fig. 8.

A kind of ball pen cutting ferrule that the present embodiment provides and ball pen pen container are in use, press contact pressing piece 5, retaining sheet 2 lower ends are inwardly shunk, so that ball pen cutting ferrule is inserted from the top of cylindrical shell, then hand push is affectedly bashful portion 14 ball pen cutting ferrule is pushed in cylindrical shell, in the time that contact pressing piece 5 arrives to 11 place, upper limit hole, projection 3, connecting rod 4 and contact pressing piece 5 just can stretch out from upper limit hole 11 under the elastic force effect of self elastic force of retaining sheet 2 or U-shaped shell fragment 6, at this moment, bottom-up pen core is inserted in hollow cylinder 1, outside needs pen core stretches out pen container bottom time, only need to push contact pressing piece 5 downwards, by connecting rod 4, projection 3 drives ball pen cutting ferrule down sliding (connecting rod 4 is in the interior slip of chute 13), in the time that projection 3 slides into 12 place, lower limit hole, just can under the elastic force effect of the elastic force of retaining sheet 2 own or U-shaped shell fragment 6, in lower limit hole 12, stretch out, thereby ball pen cutting ferrule is fixed on herein, complete pen core is pushed downwards, nib is stretched out from cylinder body bottom, after being finished, while regaining nib, same contact contact pressing piece 5, connecting rod 4 and projection 3, drive pen core upwards to walk by hollow cylinder 1, complete pen core on move, realize written retraction.

Certainly, ball pen cutting ferrule and ball pen pen container that above each embodiment provides also can use on gel ink pen, realize the adjustment of the position of the pen core of centering pen.

More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.
