Abstract

The utility model relates to a telescopic pen clip which comprises a pen clip rod and pen clip heads arranged at two ends of the pen clip rod. The pen clip rod comprises an outer barrel and an inner core which are matched with each other in a sliding mode, a thread hole is arranged in the body of the outer barrel and provided with a nut matched with the thread of the thread hole, each of the pen clip heads is of a circular structure and is provided with an opening at one end, and the pen clip heads are elastic. Two pens are clipped into the pen clip heads at two ends of the pen clip rod to be fixed, and then the inner core slides to adjust the length of the pen clip rod so as to draw parallel lines with different intervals and lengths. The telescopic pen clip is reasonable in design, flexible and convenient to use, convenient to carry and wide in application ranges and can be applied to various pens.

Description

Telescopic pen clip

Technical field

The utility model relates to a kind of clamper of writing implement, is specifically related to a kind of telescopic pen clip.

Background technology

Along with increasing of people's study and work task, the stationery of use is also more and more, and pen is of a great variety especially as main writing implement, and therefore the various aids of writing that breed also are multifarious.Yet in the utilization of drawing, particularly draw parallel lines, traditional method is exactly to draw straight line earlier beyond the set square right angle, uses ruler against another limit at set square right angle again, maintains static; Then up mobile against ruler with set square, move on to certain distance and stop and maintain static, at last along the set square other straight line that draws.Adopt this technique of painting must use two rulers, indispensable, step is haggled over loaded down with trivial details, and the straight length that draws limits to some extent less than ruler length.

Summary of the invention

In view of this, the purpose of this utility model provides a kind of telescopic pen clip, and is easy to use flexible, the parallel lines of the different spacing of can drawing and length.

The utility model discloses a kind of telescopic pen clip, comprise pen clip bar and the pen clip head that is arranged on pen clip bar two ends, described pen clip bar comprises urceolus and inner core, and described urceolus and inner core are slidingly matched.

Further, described urceolus stack shell is provided with screwed hole, and described screwed hole is provided with the nut of threaded engagement with it.

Further, described pen clip head is annular pen clip head, and the one end is provided with opening, and described annular pen clip head is the spring pen chuck.

Further, described pen clip head comprises awl tubular pen container cover, and described awl tubular pen container puts and evenly is provided with the expansion joint of extending to the middle part from big opening end.The end outside that described awl tubular pen container is with the expansion joint is provided with the dead ring that threaded engagement connects.

The beneficial effects of the utility model are: the telescopic pen clip of the utility model, and two pens are snapped in respectively in the pen clip head at pen clip bar two ends and fix, the inner core that slides is again regulated the pen clip pole length arbitrarily, the different spacing of can drawing, the parallel lines of different length.The utility model is reasonable in design, and is easy to use flexible, easy to carry, goes for various pens, applied widely.

Description of drawings

For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the I place cutaway view of the utility model Fig. 1;

Fig. 3 is the structural representation of the utility model embodiment 2.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

Embodiment 1

Fig. 1 is structural representation of the present utility model, as shown in the figure, a kind of telescopic pen clip of the utility model, comprise pen clip bar and the pen clip head 1 that is arranged on pen clip bar two ends, described pen clip bar comprises urceolus 2 and inner core 3, described urceolus 2 is slidingly matched with inner core 3, regulates the different spacing that different length satisfies parallel lines.

Fig. 2 is the I place cutaway view of the utility model Fig. 1, and as shown in the figure, described urceolus 2 stack shells are provided with screwed hole 4, and described screwed hole 4 is provided with the nut 5 of threaded engagement with it, and fastening nut 5 makes nut 5 withstand inner core 3, makes it to fix.

In the present embodiment, described pen clip head 1 is annular pen clip head, and the one end is provided with opening 6, and described annular pen clip head is the spring pen chuck, can clamp the pen of different-diameter size.

Embodiment 2

Fig. 3 is the structural representation of the utility model embodiment 2, and as shown in the figure, described pen clip head 1 comprises awl tubular pen container cover 6, evenly is provided with the expansion joint 7 of extending to the middle part from big opening end on the described awl tubular pen container cover 6.Described awl tubular pen container cover 6 has the end outside at expansion joint 7 to be provided with the dead ring 8 that threaded engagement connects.Penholder is gone into to bore in the tubular pen container cover 6, by dead ring 8 lockings that awl tubular pen container overlaps 6 outsides, realize pen fixing of different-diameter size.

Use the telescopic pen clip of the present invention, earlier two pens are snapped in respectively in the pen clip head 1 at pen clip bar two ends and fix; The inner core 3 that slides again regulates the pen clip pole length according to drawing parallel lines spacing; Rotate nut 5 at last, make it to withstand inner core 3, prevent that inner core 3 from sliding.The different spacing of can drawing, the parallel lines of different length.

Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
