Abstract

The utility model relates to a portable stylus, comprising a stylus body component, a stylus head component arranged at the lower end of the stylus body component, and a stylus cover fastened to the stylus head component, wherein the stylus head component includes a connecting seat; mounting holes with clamping components inside are arranged on the sidewalls of the connecting seat; each of the clamping components includes a guide tube, a spring in the guide tube and contact blocks; the contact blocks are located at both ends of the spring; the stylus cover is clamped with the stylus head component by the spring and the contact blocks at both ends of the spring; the stylus head further includes a strut arranged at the lower end of the connecting seat, and a hollow stylus head clamped to the strut; and the centre of the strut is provided with a vent and is communicated with the hollow stylus head. The stylus provided by the utility model has the advantages of compact and simple structure, long service life and good reliability; as the stylus head in the stylus head component adopts the hollow structure and is provided with the vent, the stylus head can be deformed and recovered smoothly without being influenced by air pressure to write better and use comfortably.

Description

Writing pencil

Technical field

The utility model relates to a kind of writing pencil, specifically is meant the external hanging type writing pencil that a kind of portable mobile terminal equipment uses.

Background technology

Along with the capacitance plate development of technology, the more and more mobile terminal device adopts capacitance touch screen as the input operation interface.For ease, people are often with the direct clicking operation capacitance plate of finger, take place overdue and problem such as character calligraph is uncomfortable through regular meeting like this.Adopt writing pencil just can address this problem easily, still, along with the development of technology and people's demand, portable terminal is miniaturization more and more, starts from cost consideration simultaneously, inevitable requirement writing pencil structure compactnesses more all, volume miniaturization and being convenient for carrying more.

Summary of the invention

The problem that the utility model need solve is a kind of compact conformation to be provided, to portably use writing pencil easily for portable terminal.

For addressing the above problem; The utility model is taked following technical scheme: a kind of writing pencil comprises a body assembly, is arranged at a written assembly of body assembly lower end and is buckled in the cap on the written assembly that written assembly comprises Connection Block; The Connection Block sidewall is established mounting hole, establishes clip assembly in the mounting hole; Said clip assembly comprises guide pipe, is located at spring and contact block in the guide pipe, and contact block lays respectively at both ends of the spring, and said cap is through the contact block and the written assembly chucking at spring and two ends thereof.

Said written assembly also comprises the pillar of being located at the Connection Block lower end, is connected in the nib on the pillar, and vent port is established at said pillar center, and said written lower end is an arc, and nib inside be hollow structure, and written inside communicates with vent port.

Establish convexity on the said nib, establish groove on the pillar of correspondence, protruding the two clamping of the interior realization of groove that is connected in pillar in nib upper end.

Said guide pipe two ends are provided with the inner recess that is used to prevent the contact block ejection.

Compared with prior art, the utlity model has following beneficial effect: (1) said writing pencil compact conformation, succinct, high life, reliability is high; (2) establish vent port in the said writing pencil nib assembly, cooperate hollow nib, do not receive barometric pressure effect when nib is write, can be out of shape smoothly and restore to the original state, be beneficial to and write, use comfortable; (3) the utility model adopts lanyard to be hung on the portable terminal outside outward, does not take the portable terminal inner space, utilizes the miniaturization Design of portable terminal.

Embodiment

In order to make those skilled in the art can understand the content of the utility model better, the utility model is done further elaboration below in conjunction with accompanying drawing and embodiment.

Like Fig. 1～shown in Figure 4, the writing pencil that present embodiment disclosed comprises lanyard 1, cap 2, a body assembly 3, written assembly 4, clip assembly 5 and the cap for brush 6.Nib assembly 4 is arranged at body assembly 3 lower end, and the two can adopt and be threaded or the interference fit connection.The cap for brush 6 is arranged at body assembly 3 upper end, and a body assembly 3 is made up of telescopic pull bar more than the joint, and topmost the cap for brush 6 is established on the pull bar top, is two sections in the present embodiment.Can easily extract second joint of a body assembly out a lengthening body by means of the cap for brush 6, adapt to certain use occasion.Cap 2 is buckled on the written assembly 3, and lanyard 1 one ends lie in cap 2 holes, and whole writing pencil can lie on the mobile device through lanyard.

Wherein, written assembly 4 comprises nib 41, pillar 42, Connection Block 43, and clip assembly 5 comprises spring 52, contact block 51, guide pipe 53.There is recess 531 at guide pipe 53 two ends of clip assembly 5, can prevent that contact block 51 from deviating from guide pipe.Clip assembly 5 is arranged in the side mounting hole 431 of Connection Block 43 of written assembly 4; The spring 52 of clip assembly 5 impels the contact block at two ends outwards outstanding; Cap 2 is buckled on the written assembly, and the compressing contact block is by the reset force and written assembly 4 chuckings of spring 52.

There is convexity 412 nib 41 inboard rear ends, cooperate with pillar 42 grooves 421, can prevent that written 41 deviate from.There is vent port 422 at pillar 42 centers, and nib 41 inside are hollow structure, and its inside communicates with vent port 422.When writing, make nib 41 not can be out of shape smoothly and restore to the original state by barometric pressure effect, conveniently write.

In the present embodiment, the lanyard 1 of writing pencil, cap 2, a body assembly 3 and the cap for brush 6 outward appearances can design various patterns, make writing pencil have more aesthetic property.

Need to prove; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection domain of the appended claim of the utility model.
