Problems solved by technology

[0003] However, due to people's usage habits and limited understanding of the functions of automatic pencils, they have not jumped out of the concept of ordinary mechanical pencils for a long time, and many people still use automatic pencils as general mechanical pencils.
In addition, full-automatic pencils have many parts, complex structures, difficult assembly, and high cost, which makes the retail price correspondingly high. Without highlighting their functions, people choose more ordinary propelling pencils, which in turn affects increased sales
[0004] In addition, the production and manufacture of fully automatic pencils is a labor-intensive industry, and its product assembly is all dependent on manual labor. It is still impossible to realize automatic assembly, which is one of the important reasons hindering the development of fully automatic pencils.

Embodiment approach 2

[0083] Such as Picture 10 As shown, the fully automatic pencil in this embodiment is a push-type, which consists of a penholder 6, a pen holder 7 arranged on the penholder 6, a pen neck 8, a pressing mechanism, and a penholder 6 and a pen neck 8. The automatic pencil movement 5 consists of a pressing mechanism including a snap head 9 and a runner 10 and a guide rail 61 arranged in the barrel 6 to cooperate with the snap head 9 and a snap spring 11 arranged in the front end of the pen neck 8. .

[0084] in Figure 10 to Figure 12 In the illustrated embodiment, the fully automatic pencil movement 5 can adopt the same structure as the first embodiment, and the rear end of the core storage part 5C is matched with the runner 10, and the front end of the tip sleeve part 5A and the snap spring 11 cooperate.

[0085] Specific as Picture 11 As shown, the rear end 592 of the core storage tube 59 of the automatic pencil movement 5 is matched with the runner 10 in the barrel 6, and the fro...

Embodiment approach 3

[0087] Such as Figure 13 As shown, the automatic pencil in this embodiment is another form of the push-type automatic pencil, which consists of a penholder 13, a pen holder 14 provided on the penholder 13, a pen neck 15, a pressing mechanism, and The pen barrel 13 and the pen neck 15 are composed of a fully automatic pencil movement 12. Among them, the pressing mechanism in this embodiment includes a press head 16 and a press core 17 respectively matched with the rear end of the core storage part 5E of the fully automatic pencil movement 12, and a tip sleeve provided in the front end of the pen neck 15 The front end of the component 5A is matched with a snap spring 11, the snap core 17 includes an elastic boss 172 that matches a pinch point 142 provided on the pen holder 14, and a side surface of the pen holder 13 is provided with a pinch point 142 and the window 131 of the elastic boss 172.

[0088] Combine Figure 14 with Figure 15 , The fully automatic pencil movement 12 in...

Abstract

The invention provides a fully-automatic mechanical pencil lead and a fully-automatic pencil with the same. The fully-automatic mechanical pencil lead comprises a sharp sleeve part, a body part and a lead storage part, the sharp sleeve part comprises a sharp sleeve, a movable damping part mounted in the sharp sleeve and a damping spring sleeving the movable damping part, and the body part is mounted in the sharp sleeve part and comprises a retainer, a clamping piece arranged in the retainer, a clamping piece spring sleeving the clamping piece and steel balls movably mounted close to the front end of the clamping piece. The lead storage part comprises a lead storage tube and a connecting portion connected with the same, and the connecting portion is connected with the rear end of the sharp sleeve part and matched with the rear end of the body part. One pencil lead penetrates the lead storage tube and the connecting portion, enters the clamping piece and penetrates out of the front end of the movable damping part for writing. The fully-automatic pencil has the advantages that the worn pencil lead can be compensated automatically during writing, and the mechanical leads of the fully-automatic pencil can be replaced mutually.

Description

Technical field [0001] The present invention generally relates to an automatic pencil, and in particular, to a mechanical pencil that can automatically compensate for the worn lead core during writing, and the movement of the automatic pencil can be replaced with each other. Background technique [0002] In the early 1980s, Germany invented a fully automatic pencil (also known as an automatic compensation pencil). Its parts are basically made of metal materials, and there are many parts, complex structures, and high processing difficulties, so it is difficult to promote. Later, Japan invented a fully automatic pencil based on plastic parts (see patent JP601700004992), which made the fully automatic pencil gradually popularized. China began mass production and sales of fully automatic pencils in the early 1990s. After nearly 30 years of development, fully automatic pencils are the simplest ones that require a lead core by hand and can only add a lead core (see patent 90210687.2),...
