Abstract

This invention relates to a pencil cover tube in stationary field, which is processed by the following steps: processing a tube with ten centimeter and a screw hole on the tube one centimeter to bottom end; then processing a screw bar into the screw hole; fixing a handle on one end of the screw bar and a block bar on the screw hole; putting eight centimeter long pencil from behind to the block bar; turning the handle to screw the bar into the tube till tightly touching the pencil for writing.

Description

Pencil sleeve

A kind of Pencil sleeve belongs to the stationery field.

The pencil that present student is used for writing is made by lead for retractable pencil and wood, when writing with this pencil, length at pencil also is left 7, during 8 centimeters left and right sides, the upper end of pencil just can not be embedded in the tiger on the staff (tiger one is exactly the place of people's thumb and forefinger infall), because the upper end of pencil can not be embedded in the tiger on the staff, so people's hand just can not be held pencil easily and write, so people just have to be also having remaining 7,8 centimeters long pencils have discarded, so just caused the waste of pencil, so existing pencil has the shortcoming that slatterns pencil.

Purpose of the present invention just is to overcome above-mentioned weak point, thereby provides a kind of pencil that can make to write only a kind of Pencil sleeve of remaining 2 centimeters left and right sides length.

The object of the present invention is achieved like this, mainly be to make earlier an interior diameter than thick slightly any hard tube (1) of most of pencils, tube length is more than about 10 centimeters, leaving a manufacturing screw (3) on about 1 centimeter tube wall of locating of pipe lower end again, the screw that can match with lead screw (5) is arranged on this screw (3) inwall, make a lead screw (5) again, the screw that can match with the screw on the screw (3) is arranged on this lead screw, and, the thickness of lead screw also matches with the diameter of screw, just lead screw can screw out precession in screw, generally speaking, lead screw is revolved and is put in screw, is fixedly mounting a handle on the end of lead screw, this handle mainly plays a part to allow staff arrest, rise when the staff rotary handle, lead screw is the and then effect of rotation also, a bit locates to be provided with a pin again on screw, this pin mainly works to block pencil, the effect that pencil can not up be filled in again.

Further specify realization of the present invention with concrete operation below, at first, people's hand is arrested handle and is rotated, make lead screw at pipe, past outside screws out point in the screw, then, be left seven only writing, the upper end of long pencil about eight centimeters, fill in from the lower end of pipe, at this moment, when if pencil is slightly slightly more some than the internal diameter of pipe, can cut pencil slightly more carefully, make not really loose ground of pencil, in just will somewhat tight jam inlet pipe, always the pencil plug till bump with pin, at this moment, fill in pencil in the pipe in two centimeters, then, rotate handle (4) again by hand, lead screw is entered toward the pipe inward turning, up to the inner end that makes lead screw push up very tightly block pencil till, at this moment a side of pencil is pushed up with tube inner wall and is tightly blocked, the opposite side of pencil is pushed up very tightly by the inner end of lead screw and blocks, like this, the upper end quilt of whole short pencil is blocked in pipe on the top firmly, the institute so that whole pencil cannot do not snapped into actively by the screw masthead, like this, short pencil and pipe (1) are in aggregates, because pipe itself just has the length more than 10 centimeters, and pencil length is as long as just can write easily more than 9 centimeters, after so present short pencil and pipe are in aggregates, its total length is very long, the people just can hold pencil or hold pipe and write, because pipe has the length more than 10 centimeters, the pipe of this length, write with regard to allowing the people hold well, so passable handle be contained in short pencil on the pipe write always collide with the lower end of pipe till, like this, have only the 1.5 centimeter long pencils of connector in pipe not write, and compare with the pencil of connector in pipe not, just can write the pencil of 5 centimeters left and right sides length more, because the pencil of connector in the present invention is when having write 7, during 8 centimeters left and right sides, just can not write again, just can only discard, in sum, thus the present invention has been reached can make pencil to write only remaining 2 centimeters long purposes.

Advantage of the present invention is: utilize lead screw be short to the short pencil top card jail that can not write in pipe after, have can make short pencil continue to write only to be left about 2 centimeters advantage.

The present invention is further illustrated with enforcement below in conjunction with accompanying drawing.

Figure of description is a structure chart of the present invention.

In Figure of description: 1. pipe 2. tube walls 3. screws 4. handles 5. lead screw 6. pins

In Figure of description: pipe (1) is tubule made from plastics or metal etc., pipe long 10 centimeters or with pipe internal diameter than most pencil slightly more slightly, about 1 centimeter away from pipe lower end locating to be provided with screw be, there is pin at upper point place at screw, pipe mainly plays a part to allow pencil enter the lower end of pipe, the lower end of pipe plays a part to help firm pencil, plays a part to allow staff hold easily, easily and writes.Wall (2) is the wall of pipe, is shaped on screw at brill on the tube wall of about 1 centimeter of pipe lower end, and tube wall mainly plays wall, and tube wall is the some of pipe.Screw (3) is in the hole that screw is arranged on the inwall that bores system on the tube wall of about 1 centimeter of pipe lower end, screw on the screw inwall can match with the screw on the lead screw, screw mainly works to allow lead screw precession or screw out point in screw, and screw is the some of pipe.Handle (4) is the some of lead screw (5), handle is fixed on the outer end of lead screw (5), handle (4) be one with plastics or a metal hyphen bar, labour-saving effect when being rotated and being rotated after handle mainly plays a part to allow staff arrest easily.Lead screw (5) is a lead screw made from metal or plastics, the screw that can match with the screw thread on the screw is arranged on the lead screw, be fixed with handle on the outer end of lead screw, lead screw is to revolve the jail on screw actively, lead screw can screw out the precession point in screw, lead screw mainly plays a lead screw precession and goes, and makes the inner end of lead screw push up the effect of blocking the pencil in the pipe very tightly.Pin (6) is little by little local on screw pole, and pin is at 1.5 centimeters places leaving the pipe lower end, and pin mainly rises and blocks pencil, make pencil can not be again the connector effect of advancing forward.
