Abstract

The utility model relates to a tumbler pen. The tumbler pen is characterized in that the tail of a pen holder of the tumbler pen is expanded and protruded, the expanded and protruded part is hollow, a weight is placed at the farthest end away from a pen point, two sides of the expanded part of the tail of the pen holder are respectively provided with a recession, and the joint of the pen holder and the part of the hand between the thumb and the index finger is provided with a recession. After the lever principle is utilized to place the pen on a table top, the pen point is inclined and still, the pen point is prevented from falling to the ground and being damaged, and the danger caused by the fact that pen points are vertically upwards after existing tumbler pens are still is reduced. In addition, the shape design of the tail of the pen holder conforms to the ergonomics, the pen holder is embedded at the part of the hand between the thumb and the index finger, the gravity of the weight at the tail end of the pen is transferred to the part of the hand between the thumb and the index finger, and writing is facilitated.

Description

Tumbler pen

Technical field

The utility model relates to a kind of tumbler pen, belongs to study article technical field.

Background technology

Known pen is cylindrical, after being finished, is placed on desk, and pen lies low on desk, and inconvenience is picked up for the second time, and easily tumbles at ground damage nib.In addition, through searching document, as Granted publication number is: 201538148 U Granted publication days of CN are: the utility model patent of 2010.08.04; Granted publication number is: 201900883 U Granted publication days of CN are: the utility model patent of 2011.07.20; Granted publication number is: 202345144 U Granted publication days of CN are: the utility model patent of 2012.07.25 is known, there is following defect in the invention of existing tumbler pen: is 1. placed on static rear nib on desk and, exists nib may stab people's danger vertically upward.2. an existing tumbler penholder is the cylindrical or conical of symmetry, and in the time writing, nib will bear the gravity of penholder afterbody weight, is unfavorable for writing.

Summary of the invention

The purpose of this utility model is to solve the problem of mentioning in above-mentioned background technology, adds counterweight at penholder afterbody, utilizes lever principle, makes pen be placed on rear nib on desk and tilts static.In addition, the design of penholder profile meets ergonomics, and penholder and people's palm thumb web place tabling, be distributed in palm thumb web place the gravity of penholder tail end counterweight while writing, is conducive to write.

The technical solution adopted in the utility model is: penholder afterbody expands projection, there are three place's recess in described part of expanding, three place's depressions are chimeric with human body palm thumb web institute, and described in expand partial interior hollow, be equipped with weight at described hollow space from nib distal-most end, the balanced lever of weight, penholder and desktop contact point and an inclination of nib composition.

The beneficial effects of the utility model are: simplicity of design, taking and placing are convenient, use safe, comfortable.

Brief description of the drawings

Fig. 1, Fig. 2 are structural representations of the present utility model: nib 1, and penholder 2, penholder both sides recess 3 and 3`, penholder contacts recess 4 with palm thumb web, and penholder afterbody expands part 5, penholder afterbody weight 6.

Detailed description of the invention

A kind of tumbler pen, as shown in Fig. 1 (front view), Fig. 2 (rearview), comprises nib 1, penholder 2, penholder both sides recess 3 and 3`, with the palm thumb web recess 4 that joins, penholder afterbody expands part 5, and described penholder afterbody expands part 5 hollows, at interior interpolation penholder afterbody weight 6.Described penholder afterbody expands part 5 three places depressions: penholder both sides recess 3 contacts recess 4 with palm thumb web with penholder with 3`.

After tumbler pen is put down, penholder afterbody weight 6 and nib 1, penholder 2 forms the lever taking pen and desktop contact point as fulcrum, ensures that thus nib tilts static, prevents that nib is impaired and eliminates the danger that a tumbler nib may be stabbed people.While writing with tumbler pen, penholder both sides recess 3 contacts recess 4 and human body palm thumb web place tabling with palm thumb web with penholder with 3`, and the force of gravity of penholder afterbody weight 6, at palm thumb web place, is ensured to write conveniently thus.

Claims (3)
