Fig. 2 is the structural representation of the pen core guide rod of a kind of propelling pencil of the utility model.

Detailed description of the invention

Illustrate, the utility model be described in further detail, in the explanation below to each figure, to " forward and backward " of pen or parts, to there is identical direction meaning below in conjunction with accompanying drawing, with along to nib outlet direction be " front ", in contrast be " afterwards ".

As depicted in figs. 1 and 2, a kind of propelling pencil, comprise retraction body 1, inside and be provided with the shell 3 that the pen core guide rod 2 of pen core through hole and inside are provided with cavity, one end of shell 3 is nib outlet 31, the cavity that retraction body 1 is located in a shell 3 exports 31 one end near nib, retraction body 1 connects pen core guide rod 2 away from one end of nib outlet 31, and one end indent that pen core guide rod 2 is not connected with retraction body 1 forms the conical surface 21, and a shell 3 madial wall is one-body molded the limiting unit 32 spacing to pen core guide rod 2.

The body 1 that wherein bounces back comprises the first spring pedestal 11, first spring 12, locking device 13, second spring 14 and the nib 15 that axially set gradually along handwriting, the first spring pedestal 11 front end is located in first top, spring 12 rear end, the first spring 12 front end is located on the top, rear end of locking device 13, the front end of locking device 13 is located in second top, spring 14 rear end, the front end of the second spring 14 is located on top, nib 15 rear end, and nib 15 can pass nib outlet 31.

Locking device 13 comprises a pipe 131, a pair stay 132 be arranged in pipe 131, be arranged on a pair ball 133 between pipe 131 inwall and stay 132 outer wall, the lock spring 134 be enclosed within outside stay 132, the locking spring abutment 135 of Inserting Tube 131 rear end and the second spring pedestal 136 of Inserting Tube 131 front end.

When after loading pen core, pen core runs through pen core guide rod 2 and retraction body 1, nib outlet 31 can be stretched by the second spring 14, with the frictional force of pen core, pen core is moved forward by nib outlet 31, locking device 13 can prevent pen core rollback, makes pen core single-way moving, it is firmly excessive when second spring 14 can prevent because writing, nib can be made to export the 31, second spring 14, locking device 13 and pen core entirety return, prevent pen core from breaking, realize the function of propelling pencil thus.

Pen core guide rod 2 is connected with the first spring pedestal 11 of retraction body 1, and specifically, one end of pen core guide rod 2 is one-body molded interpolating unit, and interpolating unit is inserted in the first spring pedestal 11 rear end.

In order to make pen core not easily be blocked by the reservoir hole in pen core guide rod 2, pen core guide rod 2 can also be made up of the first guide rod sheet 22 and the second guide rod sheet 23, the first guide rod sheet 22 and the second guide rod sheet 23 with their junction for axle is arranged axisymmetricly.

Wherein, the one side that first guide rod sheet 22 is opposite in the second guide rod sheet 23 is provided with salient point 24, the one side that second guide rod sheet 23 is opposite in the first guide rod sheet 22 is provided with the groove 25 be equipped with salient point 24, and the connection between the first guide rod sheet 22 and the second guide rod sheet 23 can be made thus more stable.

One end that shell 3 does not arrange nib outlet 31 can also be provided with core ejecting device 4, and core ejecting device 4 comprises plunger tip and emits 41 and be shaped in the plunger tip bar 42 that plunger tip emits 41, and plunger tip bar 42 is inserted in the cavity of a shell 3 inside.Thus, when filling pen core, with plunger tip bar, pen core being advanced further, better can fill pen core.

Plunger tip emits 41 can also be embedded with erasing rubber with the opposing one end of plunger tip bar 42.Thus, the word utilizing pen core to write can be cleaned.

In sum, pen core, by arranging pen core guide rod in penholder, when filling pen core, can be introduced in retraction body, conveniently fill pen core by the utility model.

The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, under the prerequisite not departing from the utility model creation design; can also make some similar distortion and improvement, these also should be considered as within protection domain of the present utility model.
