Embodiment Construction

[0009] specific implementation plan

[0010] On the structure of the existing automatic pen, two cuboids (2) of appropriate size and length are installed on the symmetrical position of the button (1) by using bonding technology. The technology forms two grooves (4), and makes the size, length and spacing of the grooves (4) consistent with those of the cuboid object (2) on the button (1).

Abstract

The invention provides a protecting device of a propelling pencil button. The protecting device which can prevent the propelling pencil button from being pressed down at any time is characterized in that on the basis of the structure of an existing propelling pencil, two rectangular objects are symmetrically mounted on the propelling pencil button, two grooves are formed in the top end of a propelling pencil rod at the same time, and the size and the interval of the grooves are identical with the size and the interval of the rectangular objects. During use, the rectangular objects on the propelling pencil button are aligned with the grooves in the top end of the propelling pencil rod, and the propelling pencil button can be pressed down. When the propelling pencil is not used, the grooves are staggered with the rectangular objects, the propelling pencil button cannot be pressed down, and the tip of the propelling pencil can be protected.

Description

technical field [0001] The invention relates to a novel automatic pen button protection device for preventing the automatic pen button from being pressed. Background technique [0002] In daily life, automatic pens are used more and more frequently. Due to their convenience, they have replaced traditional fountain pens to a certain extent. At present, most automatic pens are composed of a button, a pen holder, a spring, and an internal refill. When in use, the button can be pressed to use, and after use, the pen tip can be retracted through the button. But in real life, it often happens that the nib is pushed out by accidentally pressing the button, which is not conducive to the protection of the nib and will bring unnecessary troubles. Contents of the invention [0003] In order to overcome the instability of the existing automatic pen button, the present invention provides a new type of automatic pen button protection device that can prevent the automatic pen button fro...
