Abstract

The utility model provides a two-purpose pencil with eraser on top. A square cylinder, a square head screw, a screw plug and a cylinder are orderly connected inside the two-purpose pencil with eraser on top. The screw-shaped of the square head screw is matched with the screw-shaped of the screw plug, and the screw-shaped of the square head screw and the screw plug are screwed together, the square head part of the square head screw and the screw part of the square head screw are respectively inserted into the square cylinder and the cylinder. The screw plug is fixed with the casing of the pencil together, a screw head on the upper end of the pencil is connected with the square cylinder. The two-purpose pencil with eraser on top rotates the screw head to drive the square head screw inside the pencil rotates together, and simultaneously, the screw head moves up and down to push-out the lead block or eraser inside the pencil to realize the functions of writing or accurate correcting. A hair brush is attached on the screw head to sweep the eraser dust which sticks on the paper after correcting.

Description

Have accurate correction and write pen double-duty

Affiliated technical field

The utility model relates to and a kind ofly has accurate correction and write pen double-duty.

Background technology

Existing correction apparatus mostly is into the rubber of piece, use a period of time after, the rubber rounding is easy to the place that should not wipe has also been wiped when altering, and also will fill again during modification, reduced operating efficiency, especially for draw and the art designing work such as to design be very disadvantageous.

Summary of the invention

The purpose of this utility model provides a kind of can the correction accurately writing the mistake that occurs in the drawing, and can not wipe other parts, also can be used as the multipurpose tool that pencil uses simultaneously.

The utility model is to realize like this, in the shell of pen, square tube, the square toes screw rod, nut insert and cylinder are linked in sequence, the two screw thread of square toes screw rod and nut insert is complementary and spins together, the square toes part of square toes screw rod is inserted in square tube respectively with threaded shank, in the cylinder, nut insert is fixed together with the shell of pen, the head that revolves of pen upper end links together with square tube, when rotation was revolved, square tube was and then rotated, and the square toes screw rod that drives simultaneously in it rotates together, under the effect of nut insert, the square toes screw rod will move up and down, if put into lead block or rubber column in cylinder, the square toes screw rod just can eject it.Also have hairbrush on the head revolving of pen, be used to clear away the rubber bits that are bonded on the paper.

The beneficial effects of the utility model are that sound construction can be reused.As correction pen, it can be wiped accurately to mistake, and can clear away the rubber bits that are bonded on the paper; As pencil, non-sharpenning in use, and save timber.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structure assembly drawing of the present utility model;

Fig. 2 is the stereogram of three kinds of core components in the pen.

1. revolve head (on hairbrush is arranged) among the figure, and 2, Shang shell, 3, square tube, 4, nut insert, 5, the square toes screw rod, 6, cylinder, 7, the shell of starting writing,

The specific embodiment

With reference to Fig. 1, revolving head (a 1) lower end has square toes can insert in the square hole of square tube (3), and square tube (3) can not pass from the circular hole of last shell (2) upper end, and the three just combines like this.

Nut insert (4) plug has screwed hole in the middle of it among the shell of starting writing (7), internal thread cooperates with square toes screw rod (5), and in order to prevent relative slip in use to occur, the lift angle of screw thread should be less than 5 °.

Nut insert (4) respectively has a circular groove up and down, and the circular groove of upper end is located square tube, prevents that it from swinging, and the circular groove of lower end then plays fixation to cylinder (6), uses the lower port of cylinder (6) to be angle for convenient.

Square tube (3), cylinder (6) and square toes screw rod (5) three are coaxial, and the external diameter of the internal diameter of the endoporus length of side of square tube (3), cylinder (6) and square toes screw rod (5) equates, to prevent bent screws.Three's shape can be from stereogram--more is clear that-Fig. 2.

Claims

1. one kind has accurate correction and writes pen double-duty, in the shell of pen, square tube, square toes screw rod, nut insert and cylinder are linked in sequence, it is characterized in that: the two screw thread of square toes screw rod and nut insert is complementary and spins together, and the square toes of square toes screw rod, screw portion are inserted in respectively in square tube, the cylinder.
