Abstract

A pen capable of preventing mistaken scratching is characterized by comprising a pen head (1), a pressing device (2), a connecting shaft (2-1), a pressing plate (2-2), a concave body (2-3), a reset spring (3), a thread (4), a pen core (5), a pen point (5-1), a spring stop piece (5-2), a pen core rod (5-3) and the like, normal writing and using can be realized when a user uses the pen, the pen core automatically returns into a pen shell when the user does not use the pen, and the problem that the pen oil is scratched on book files, human skins and clothes by mistake is avoided.

Description

Error-stroke-preventing pen

Technical Field

The utility model relates to a prevent mistake pen-drawing belongs to the stationery field.

Background

Most of the pens available on the market are push-type pens or pens with pen caps, which are searched by the Howept and related patents. However, such a pen has a problem in that if a cap is not timely applied or the cartridge is withdrawn into the barrel by pressing a button during use, the pen is easily inadvertently stroked on some book documents and the skin and clothes of a user, while the ink of a gel pen stroked on paper is not substantially removed, and in case of some important documents, the pen is seriously affected, and in case of being carelessly stroked on clothes, the pen is difficult to clean. In addition, if the pen is inadvertently dropped on the ground when the cap is not applied or the pen core is withdrawn into the barrel by pressing the button, the ball of the pen core is easily dropped.

Disclosure of Invention

The defect to current product, the utility model discloses corresponding change design has all been made to shell and refill.

An anti-error-stroke pen is characterized by comprising a pen point (1), a pressing device (2), a return spring (3), a thread (4) and a pen core (5), wherein the pen point (1) is connected with a pen shell through the thread (4), the pressing device (2) is formed by a connecting shaft (2-1), a pressing plate (2-2) and a concave body (2-3) together, the specific structure is that the pressing plate (2-2) is excavated on the upper part of the thread (4) for connecting the pen shell with the pen point (1), the pressing plate (2-2) is connected with the pen shell through the connecting shaft (2-1), the concave body (2-3) is arranged on one side of the pressing plate (2-2) close to the pen shell and is connected with the connecting shaft (2-1), the other end of the concave body (2-3) is pressed at the rear end of a spring stopper (5-2) of the pen core, the refill (5) consists of a pen point (5-1), a spring stopper (5-2) and a refill rod (5-3), wherein the front end of the spring stopper (5-2) of the refill is provided with a return spring (3), and when a user does not write, the user can push the spring stopper (5-2) through self elasticity to enable the refill to move upwards and return into the refill rod.

The lower end of a concave body (2-3) of the pressing device is contacted with a spring blocking piece (5-2) of the pen core, when a user uses the writing pen, the pressing plate (2-2) of the pressing device (2) is pressed by hands, and the lower end of the concave body (2-3) pushes the spring blocking piece (5-2) of the pen core to move downwards until the pen tip (5-1) is exposed out of the pen head (1) so as to be used for writing normally under the driving of a connecting shaft (2-1). Meanwhile, the spring stopper (5-2) of the refill compresses the return spring (3).

When a user does not write and use the pen, fingers can not pinch the pressing device (2) at the lower end of the pen naturally, the pressure on the pressing plate (2-2) is reduced at the moment, the pressure acting on the spring blocking piece (5-2) of the pen core through the lower end of the concave body (2-3) is also reduced according to the force transmission, the elastic force of the reset spring (3) below the spring blocking piece (5-2) is far greater than the force acting on the upper part of the spring blocking piece (5-2) of the pen core, and the reset spring (3) pushes the spring blocking piece (5-2) to enable the pen core to move upwards under the action of the elastic force of the reset spring (3) at the moment so as to enable the pen core to return into the pen core rod.

The pen point (5-1) of the refill used by the utility model is longer than the replacement refill of the common gel ink pen, so as to be suitable for the compression distance of the reset spring (3) below the spring retainer (5-2).

FIG. 4: structure of pressing device (2)

The pen comprises a pen point (1), a pressing device (2), a connecting shaft (2-1), a pressing plate (2-2), a concave body (2-3), a return spring (3), a thread (4), a pen core (5), a pen point (5-1), a spring blocking piece (5-2) and a pen core rod (5-3);

Detailed Description

The pen point (1) is connected with the pen shell through the threads (4) of the pen point (1) and the pen shell, when the pen point (1) is used, the threads (4) between the pen point (1) and the pen shell are rotated to dismount the pen point (1), the pen core (5) penetrates through a gap in the middle of the concave body (2-3) to be placed in the pen shell, the spring blocking piece (5-2) of the pen core is made to abut against the concave body (2-3) of the pressing device (2), then the reset spring (3) is sleeved on the pen point (5-1) of the pen core, and the threads (4) between the pen point (1) and the pen shell are rotated to mount the pen point (1).

When the pen is used for writing, fingers can naturally press the pressing device (2) while holding the pen, the pen core (5) is pushed downwards under the action of the pressing device, and the pen point (5-1) is exposed out of the pen head (1) so that normal writing can be carried out.

After the pen is used, due to the change of the pen holding posture, the pressure of fingers on the pressing device (2) is reduced or even disappears, and the pen core (5) retracts into the pen shell under the action of the elastic force of the return spring (3).
