Description

A kind of pencil adds thick bar

Technical field

This utility model relates to field of stationery, and specifically a kind of pencil adds thick bar.

Background technology

Pencil is a kind of to facilitate handy office stationary, the diameter of usual pencil-lead is fixing, but in order to increase the comfort level held a pen, the penholder of pencil generally can be more much larger than pen core diameter, this has resulted in the timber large usage quantity producing material as pencil holder, further result in the waste of timber, and make in pencil process, wood pen holder is indispensable, because wood pen holder not only easily cuts but also can play an important role for protection pen core, therefore how saving timber under the premise ensureing pencil performance makes consumption be a very important research topic.

Utility model content

Technical problem to be solved in the utility model be to provide a kind of not only can guarantee that pencil performance but also timber can have been saved make the pencil of consumption add thick bar.

The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of pencil adds thick bar, including cylindrical shape rod member and clamping device, the inner chamber of described rod member is identical with by overstriking pencil diameter, the described thick pencil that added through the inner chamber of rod member and is stretched out outside rod member by the written end adding thick pencil, rod member is fastened to and is added in thick pencil by described clamping device, described clamping device includes groove and grip block, described groove is arranged on rod member outer wall, the through rod member in its one end is towards being added the end face of the written end of thick pencil, described grip block is the rectangular slab corresponding with groove, one end of described grip block is hinged end, described hinged end both sides are provided with the second rotating shaft, two relative sidewalls of described groove are provided with the duct corresponding with the second rotating shaft, described grip block is hinged by the second rotating shaft and duct and rod member, the described grip block other end is fixing connects pinching end, described pinching end is to being added the boss that thick pencil extends and is perpendicular to center line of the bar, described pinching end is the indent arcwall face that diameter is identical with pencil diameter towards the one side of pencil, the arcwall face of described pinching end is provided with the cutting shoe of projection, when grip block turns to the position parallel with center line of the bar, the arcwall face of described pinching end just contacts with the outside wall surface of pencil, described cutting shoe is blocked and is added thick pencil.

Assemble this pencil when adding thick bar, first grip block is lifted, then pencil is penetrated rod member inner chamber, press grip block again, make grip block pinching end be close to pencil surface, make the cutting shoe of pinching end arcwall face embed the wood pen holder of pencil, strengthen the fastening force of pencil overstriking pole pair pencil.

The beneficial effects of the utility model are: after using this pencil to add thick bar, can allow significantly to reduce the diameter of pencil wood pen holder, and then the timber that pencil is greatly reduced makes consumption, cutting shoe can strengthen the fastening force of pencil overstriking pole pair pencil simultaneously, prevent from pencil from adding in thick bar at pencil to slide, affect pencil serviceability, and this pencil adds thick bar and can also can use as extension rod for pencil by Reusability, convenient and practical.

On the basis of technique scheme, this utility model can also do following improvement.

Further, described pencil adds thick bar and also includes the first rotating shaft, the two ends of described first rotating shaft are respectively fixedly connected with on two relative sidewalls of groove, and described first rotating shaft is at grip block hinged end and groove between the one end away from grip block pinching end, described first rotating shaft is cased with straight-arm torque spring, and two straight-arms of straight described arm torque spring contact with the outer wall of grip block hinged end and the bottom surface of groove respectively, this device can increase grip block to being added the fastening force of thick pencil, prevent grip block from getting loose, make pencil add thick bar more convenient and practical.

Further, described clamping device quantity is two, and symmetrical about center line of the bar, and this structure can make pencil stress more balanced, and clamping effect is better.

Further, described grip block deviates from the one side of pencil and is fixedly connected with rubber antiskid pad, it is possible to increases the comfort level held a pen, and is possible to prevent pencil to skid in writing process.

Detailed description of the invention

Below in conjunction with accompanying drawing, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model.

As shown in the figure, pencil described in the utility model adds thick bar, including cylindrical shape rod member 1 and clamping device, the inner chamber 101 of described rod member 1 is identical with being added thick pencil 5 diameter, the described thick pencil 5 that added through the inner chamber 101 of rod member 1 and is stretched out outside rod member 1 by the written end adding thick pencil 5, described clamping device includes groove 102 and grip block 2, described groove 102 is arranged on rod member 1 outer wall, the through rod member in its one end 1 is towards being added the end face of the written end of thick pencil 5, described grip block 2 is the rectangular slab corresponding with groove 102, one end of described grip block 2 is hinged end 201, described hinged end 201 both sides are provided with the second rotating shaft 204, two relative sidewalls of described groove 102 are provided with the duct 103 corresponding with the second rotating shaft 204, described grip block 2 is hinged with rod member 1 by the second rotating shaft 204 and duct 103, described grip block 2 other end is fixing connects pinching end 202, described pinching end 202 is to being added the boss that thick pencil 5 extends and is perpendicular to rod member 1 axis, described pinching end 202 is the indent arcwall face that diameter is identical with pencil 5 diameter towards the one side of pencil 5, the arcwall face of described pinching end 202 is provided with the cutting shoe 203 of projection, when grip block 2 turns to the position parallel with rod member 1 axis, the arcwall face of described pinching end 202 just contacts with the outside wall surface of pencil 5, described cutting shoe 203 is blocked and is added thick pencil 5, described pencil adds thick bar and also includes the first rotating shaft 4, the two ends of described first rotating shaft 4 are respectively fixedly connected with on two relative sidewalls of groove 102, and described first rotating shaft 4 is at grip block hinged end 201 and groove 102 between the one end away from grip block pinching end 202, described first rotating shaft 4 is cased with straight-arm torque spring 3, and two straight-arms of straight described arm torque spring 3 contact with the bottom surface of the outer wall of grip block hinged end 201 and groove 102 respectively.
