Several clamping hole forming sections of pen core introduction segment and pen core export section are connected,

Wherein, the clamping hole forming section and pen core introduction segment are arc section, and pen core export section is to extend straight down Straightway, pen core introduction segment and pen core export section is separated by a distance is located at pen core between the two to be formed and imports and exports.

Preferably, the center of circle of pen core introduction segment is passed in and out in the outside of clamping pore structure, pen core introduction segment in the pen core Mouthful at tangent line and horizontal plane between at angle α.

Preferably, the angular range of angle α is 30 °~75 °.

Preferably, the clamping hole forming section includes exporting section from pen core introduction segment to pen core to be sequentially connected and adjacent two Section tangent the first profiled section, the second profiled section, third profiled section, the 4th profiled section and fifth forming section two-by-two, wherein first Profiled section and pen core introduction segment are tangent, and fifth forming section is connected with pen core export section.

Preferably, fifth forming section and pen core export section are equipped with rounded transition.

Preferably, the circle of the first profiled section, the second profiled section, third profiled section, the 4th profiled section and fifth forming section The heart is in the inside of clamping pore structure.

Preferably, it is assumed that pen core introduction segment, the first profiled section, the second profiled section, third profiled section, the 4th profiled section and The radius of fifth forming section is respectively R1, R2, R3, R4, R5 and R6, then has R2 > R4 > R1 > R3 > R6 > R5.

Preferably, the bore of the pen core inlet and outlet is greater than the diameter of pen core to be clamped.

The utility model compared with prior art, the beneficial effect is that:

It uses more reasonable structure to design, and can be improved the speed in pen core disengaging clamping hole, greatly improves pen core and pressing from both sides Success rate is taken, to improve the efficiency of pen core transfer, and then improves subsequent pen core sheath installation effectiveness.

Detailed description of the invention

Fig. 1 is the front view that the clamping pore structure of clamping jaw is shifted according to pen core described in the utility model.

Specific embodiment

The following describes the utility model in further detail with reference to the accompanying drawings, the aforementioned and other mesh of the utility model , features, aspects and advantages will be apparent, to enable those skilled in the art's refer to the instruction text real accordingly It applies.In the accompanying drawings, for clarity, shape and size can be amplified, and identical attached drawing mark will be used in all figures Note is to indicate the same or similar component.In the following description, such as center, thickness, height, length, front, back, rear portion, The words such as the left side, the right, top, bottom, top, lower part are to be based on the orientation or positional relationship shown in the drawings.Particularly, " high Degree " is equivalent to size from the top to the bottom, and " width " is equivalent to size from left to right, and " depth " is equivalent to be arrived in the past Size afterwards.These relative terms are to be not intended to need specifically to be orientated for convenience and usually.Be related to attachment, Connection etc. term (for example, " connection " and " attachment ") refer to these structures pass through intermediate structure directly or indirectly to one another fixation or The relationship of attachment and movable or rigidly attached or relationship, unless otherwise clearly stating.

Referring to Fig.1, the clamping pore structure 6525 of pen core transfer clamping jaw includes:

Pen core introduction segment S1；

The pen core opposite with pen core introduction segment S1 exports section S7；And

Several clamping hole forming sections of pen core introduction segment S1 and pen core export section S7 are connected,

Wherein, the clamping hole forming section and pen core introduction segment S1 are arc section, and it is straight down that pen core, which exports section S7, The straightway of extension, pen core introduction segment S1 and pen core export section S7 it is separated by a distance with formed be located at pen core between the two into Outlet.When clamping, pen core enters in clamping pore structure 6525 from pen core import and export, clamps hole forming section by several After guidance, skidded off again from pen core import and export after making short stay in clamping pore structure 6525, whole process is smooth, nothing is paused It frustrates, substantially reduces the probability that pen core gets stuck, improve pen core clamping success rate.

Further, the center of circle of pen core introduction segment S1 is in the outside of clamping pore structure 6525, and pen core introduction segment S1 is described Between the tangent line and horizontal plane of pen core import and export at angle α.Pen core can be further increased using this structure and enter clamping The smoothness of pore structure 6525.

Further, the angular range of angle α is 30 °~75 °.In one embodiment, α=30 °；In another embodiment party In formula, α=75 °；In a preferred embodiment, α=45 °.

Further, the clamping hole forming section includes exporting section S7 from pen core introduction segment S1 to pen core to be sequentially connected and phase Adjacent two sections tangent the first profiled section S2, the second profiled section S3, third profiled section S4, the 4th profiled section S5 and fifth formings two-by-two Section S6, wherein the first profiled section S2 and pen core introduction segment S1 are tangent, and fifth forming section S6 is connected with pen core export section S7.

In a preferred embodiment, fifth forming section S6 and pen core export section S7 are equipped with rounded transition.

Referring to Fig.1, the first profiled section S2, the second profiled section S3, third profiled section S4, the 4th profiled section S5 and fifth forming The center of circle of section S6 is in the inside of clamping pore structure 6525.

Further, it is assumed that pen core introduction segment S1, the first profiled section S2, the second profiled section S3, third profiled section S4, the 4th The radius of profiled section S5 and fifth forming section S6 are respectively R1, R2, R3, R4, R5 and R6, then have R2 > R4 > R1 > R3 > R6 > R5.Such as Shown in Fig. 1, pen core enters clamping pore structure 6525 from S1 sections, successively passes through the first profiled section S2, the second profiled section S3, wherein the Two profiled section S3 are in the highest point of clamping pore structure 6525, i.e. the pen core highest that reaches the second profiled section S3 after first undergoing the ascent stage At point, due to R2 > R3, so that pen core invades speed under the collective effect of gravity and profiled section S2 and gradually eases up, and finally exist Stop at the highest point of second profiled section S3；When pen core will be skidded off from clamping pore structure 6525, successively pass through third profiled section S4, the 4th profiled section S5 and fifth forming section S6, due to R4 > R6 > R5, its slip velocity gradually increases pen core during the fall Greatly, and in fifth forming section S6 go out slightly to be restricted, so that its final slip velocity is unlikely to excessive, so as to avoid pen core From clamping pore structure 6525 skid off when due to speed it is excessive caused by park shakiness.

Further, the bore of the pen core inlet and outlet is greater than the diameter of pen core to be clamped.

Number of devices and treatment scale described herein are the explanations for simplifying the utility model.To the utility model Application, modifications and variations will be readily apparent to persons skilled in the art.

Although the embodiments of the present invention have been disclosed as above, it is not limited in institute in specification and embodiments Column use, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, can Easily realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, this is practical It is novel to be not limited to specific details and legend shown and described herein.
