Abstract

The utility model discloses a pressing type automatic pencil, which relates to a key structure, a pencil holding finger position structure, the connection of an eraser cap, and the preservation of an inner storing lead core. The front half section of the outer tube of the pencil presents a tube shape whose inner circle is hollow, and the outside of the tube shape is arc edges of the equal triangle, and the tail half section of the outer tube of the pencil is a circular tube shape. A pair of openings for containing the key to slide are arranged on the tail end of the outer tube of the pencil, and the key is that three plastic beads which are fixed separately are penetrated on a fine iron wire. The end of the outer tube of the pencil is tightly inserted into the front end of a connecting tube, and a large eraser cap is inserted on the rear end of the connecting tube; a nail-shaped plug is plugged on the tail end of an inner tube for storing lead core, and the tail end of the plug is adjacent to the key. The pressing type automatic pencil has novel key, the lead core can be controlled and adjusted freely. The utility model can prevent and correct the erroneous finger position of holding the pencil, the imperfect sitting posture can also be prevented and corrected, and the utility model is favorable for writing by holding the pencil. Because the utility model adopts a large eraser cap, the utility model is convenient to be used, and the utility model can prevent the shortage that the inner storing lead core dissipates with the drop of the tail key.

Description

Pressing type automatic pencil

The utility model is a kind of press-key structure that relates to, correcting holds a pen refer to bit architecture, erasing rubber head syndeton and prevent in the be scattered propelling pencil of structure of the plumbous stamen of storage.

At present, known propelling pencil is made up of nib pipe, outer garden pipe, unidirectional folder lead component, the plumbous stamen pipe of interior storage, afterbody button.The alternate hexagonal pipe of size is made in recent modified has outer garden pipe is changed, and is

Shape.In the afterbody button that has or microcephaly's erasing rubber head is housed.Though these propelling pencils have solved and have store plumbous stamen and the regulated at will pencil lead exposes or the problem of indentation,, the afterbody button comes off easily, and the plumbous stamen of interior storage also is scattered thereupon and loses.Adopt the afterbody button, the setting of unfavorable erasing rubber head of afterbody or big erasing rubber head.Outer tube is the garden pipe, and unfavorable student holds a pen and writes, and particularly unfavorable beginner holds a pen and writes, and causing easily holds a pen refers to that bit-errors and sitting posture are bad, thereby influences writing quality and healthy.Though the alternate hexagon outer tube of recent improved size holds a pen to rectification and refers to that the position has certain effect, student to hold a pen and still has sense of discomfort, and the unfavorable major part erasing rubber of tail shape and space head connects.The afterbody button is not pacify the erasing rubber head, is exactly that diameter only is housed is 4mm garden column microcephaly erasing rubber head.This little erasing rubber head must be changed frequent, uses inconvenience.

The purpose of this utility model provides a kind of suitable press-key structure, and favourable rectification holds a pen and refers to an outer tube of bit architecture, can connect the structure of major part erasing rubber head, the plumbous stamen of the storage propelling pencil of structure that is scattered in preventing.Make button freely, an afterbody difficult drop-off is store unlikely being scattered of plumbous stamen and is lost, and big erasing rubber head can be installed, and favourable student holds a pen and writes.

The purpose of this utility model is achieved in that the plumbous stamen pipe of interior storage front end is connected with unidirectional folder lead component rear end that unidirectional folder lead component front end is connected with nib pipe spiral by an outer tube front end.The outer tube tail of pen is made the garden pipe for half section, and tail end is split an openning, holds connecing the key slip.Wear 3 little plastic beads and separately fixing in twos with thin wire, as button.Button is put into openning make vertical back and forth movement,, regulate pencil lead and expose or indentation with the plumbous stamen pipe motion of storage in promoting along an outer tube.With before the outer tube of pen half section make in the garden sky tubulose on triangle arc limit such as be outward.Outer tube preceding half section with smooth connection of tail half section surface, an outer tube tail end closely inserts tube connector one end, the tube connector other end inserts big erasing rubber head.Tube connector connects back control button scope of activities, stop button from after come off.The plumbous stamen pipe afterbody of interior storage with a nail type stopper beyond the Great Wall.Nail type plug tail and button are close.Reach button freely, correcting holds a pen refers to the position, and being beneficial to holds a pen writes, and big erasing rubber head is installed, the purpose that the plumbous stamen of storage is scattered in preventing.

Adopt such scheme, this button novelty controls to adjust plumbous stamen freely, eliminates the deficiency that the afterbody button easily comes off.Be beneficial to prevention and finger position and the incorrect sitting-pose of holding a pen that correct a mistake, favourable holding a pen write, and improves writing quality.Big erasing rubber head is easy to use, eliminates little erasing rubber head and must change frequent worry.The storage plumbous stamen easy random notes afterbody button lost deficiency that comes off in preventing.This propelling pencil overall style novel and beautiful, rational in infrastructure, easy to manufacture, be comparatively ideal writing implement.

Below in conjunction with accompanying drawing the utility model is further described.

Figure one is the longitudinal sectional drawing of a kind of concrete structure of the utility model.

Figure two is figure one propelling pencil cutaway views along the B-B line.

Among the figure 1, nib pipe 2, unidirectional folder lead component 3, preceding half section 4 an of outer tube, the plumbous stamen pipe 5 of interior storage, half section 6 on an outer tube tail, button 7, tube connector 8, erasing rubber head 9, nail type stopper

In figure one, the garden sky such as was outward at the tubulose on triangle arc limit in an outer tube preceding half section (3) was made, and cross section is shown in figure two, and an outer tube tail half section (5) is made the garden tubulose, and half section (5) smooth surface of an outer tube preceding half section (3) and an outer tube tail is connected.Interior storage plumbous stamen pipe (4) front end is connected with unidirectional folder lead component (2) rear end.Unidirectional folder lead component (2) front end is connected with nib pipe (1) spiral by preceding half section (3) front end of an outer tube.Half section (5) tail end of outer tube tail split an openning, and long 18mm widely can hold the motion of 1mm thin wire.Wearing three diameters with the 1mm thin wire is 4mm plastic bead and separately fixing in twos as button (6).Button (6) is put into half section (5) tail end openning of an outer tube tail, make vertical back and forth movement,, expose or indentation to regulate pencil lead in order to the plumbous stamen pipe of storage (4) motion in promoting along an outer tube.Half section (5) tail end of an outer tube tail closely inserted tube connector (7) front end, and tube connector (7) other end inserts diameter and lives the big erasing rubber head of shape (8) for the 10mm garden, and erasing rubber head (8) can be changed.Tube connector (7) connects the scope of activities of back control button (6), stop button (6) from after come off.Interior storage plumbous stamen pipe (4) afterbody with nail type stopper (9) beyond the Great Wall.Nail type stopper (9) afterbody and button (6) are close.
