Abstract
A pair of pliers for holding chalk during writing is characterized in that two fixing fins (3) are respectively arranged in grooves at the right ends of an upper holding rod (1) and a lower holding rod (2), the cross sections of the upper holding rod (1) and the lower holding rod (2) are in a ring fan shape, and the middle of every fixing fin (3) is provided with a shaft hole; a shaft hole is respectively formed in the right portion of the long transverse plate of an L-shaped connecting plate (5) and in the lower portion of the short vertical plate of the L-shaped connecting plate (5); the long transverse plate is arranged between two fixing fins (3) of the upper holding rod (1) through a shaft (4) in a connection mode; the short vertical plate is arranged between the two fixing fins (3) of the lower clamping rod (2) through a shaft (4) in a connection mode; the length of the upper holding rod (1) is smaller than that of the lower holding rod (2), and the grooves of the upper holding rod and the lower holding rod are opposite. Thin chalk cannot be broken when being arranged in the pair of pliers for writing, the strokes of the writing written by the thin chalk are thin, and the chalk can be saved; the contact time of the hand of a teacher and the chalk is reduced, so that the pair of pliers for holding the chalk during writing is beneficial to the health of the teacher.
Description
Technical field
The utility model relates to a kind of pliers, is specifically related to a kind of pliers of seizing chalk when writing on both sides by the arms.
Background technology
When teacher write letter written with chalk, teacher's hand contacted with chalk all the time, and chalk is bigger to the corrosion of teacher's hand, diminished teacher's health.The teacher who has lives chalk with paper bag and writes, but compares trouble, time-consuming like this.In addition, because present chalk is thicker, therefore the stroke of the letter written with chalk that writes out is also very thick, has wasted chalk; If but chalk is thinner, but can fracture easily because of its insufficient strength, the inconvenience of writing also causes waste.The method that addresses these problems is a kind of pliers of seizing chalk when writing on both sides by the arms of design, the fine powder pen is installed in this pliers writes, and then the fine powder pen can not fractureed, and teacher's hand also has been subjected to protection.
The utility model content
The purpose of this utility model is for market provides a kind of pliers of seizing chalk when writing on both sides by the arms, in order to adopt the fine powder pen to write to economize on resources, also avoids chalk that teacher's hand is caused corrosion.
The technical solution adopted in the utility model is: described a kind of feature of seizing the pliers of chalk when writing on both sides by the arms: arrange cross section for ring hold under the arm on fan-shaped bar and under hold bar under the arm; Hold bar on described under the arm and hold under the arm down in the right-hand member groove of bar and respectively be provided with two fixed wings, the axis hole that it is horizontal direction that the middle part of described four fixed wings respectively is provided with an axis, hold equal diameters and the dead in line of two axis holes of the fixed wings of bar on described under the arm, equal diameters and the dead in line of two axis holes of described fixed wings of holding bar down under the arm; Connecting plate is set; Described connecting plate is L shaped, has a long transverse slat and a short riser, the axis hole that it is horizontal direction that the bottom of the left part of described long transverse slat and short riser respectively is provided with an axis; Described long transverse slat is installed between two fixed wings of holding bar under the arm by axle and connects, described axle with on hold the fixed wings of bar under the arm axis hole be interference fit, described axis hole with long transverse slat is matched in clearance; Described short riser is installed in down between two fixed wings of holding bar under the arm and is connected by axle, and described axle is interference fit with the axis hole of holding the fixed wings of bar down under the arm, and described axle is matched in clearance with the axis hole of short riser; The length of holding bar on described under the arm is relative less than the length of holding bar down under the arm and both grooves.
Illustrate: perpendicular on the cross section of holding bar under the arm and holding down the length direction of bar under the arm be called cross section.
Beneficial effect: the fine powder pen is installed in this pliers writes, the fine powder pen can not fractureed, and the writing stroke of writing out is thin, can save chalk; No matter be meal pen or fine powder pen, this pliers can both be seized on both sides by the arms; No matter be that major part with chalk is placed on to hold under the arm in the bar or the microcephaly of chalk is placed on and holds under the arm in the bar, this pliers can both be seized on both sides by the arms; Teacher's hand and the time of contact of chalk reduce, and teacher's healthy and beneficial is used.
Description of drawings
Fig. 1 is a kind of front view be used to the pliers of seizing chalk on both sides by the arms.
Among the figure: hold bar 1, under the arm; 2, hold bar down under the arm; 3, fixed wings; 4, axle; 5, connecting plate.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail: a kind of pliers of seizing chalk when writing on both sides by the arms is characterized in that: arrange cross section for ring fan-shaped on hold under the arm bar 1 and under hold bar 2 under the arm; Hold bar 1 on described under the arm and hold under the arm down in the right-hand member groove of bar 2 and respectively be provided with two fixed wings 3, the axis hole that it is horizontal direction that the middle part of described four fixed wings 3 respectively is provided with an axis, hold equal diameters and the dead in line of two axis holes of the fixed wings 3 of bar 1 on described under the arm, equal diameters and the dead in line of two axis holes of described fixed wings 3 of holding bar 2 down under the arm; Connecting plate 5 is set; Described connecting plate 5 is L shaped, has a long transverse slat and a short riser, the axis hole that it is horizontal direction that the bottom of the left part of described long transverse slat and short riser respectively is provided with an axis; Described long transverse slat is installed between two fixed wings 3 of holding bar 1 under the arm by axle 4 and connects, described axle 4 with on hold the fixed wings 3 of bar 1 under the arm axis hole be interference fit, described axle 4 is matched in clearance with the axis hole of long transverse slat; Described short riser is installed in down between two fixed wings 3 of holding bar 2 under the arm and is connected by axle 4, and described axle 4 is interference fit with the axis hole of holding the fixed wings 3 of bar 2 down under the arm, and described axle 4 is matched in clearance with the axis hole of short riser; The length of holding bar 1 on described under the arm is relative less than the length of holding bar 2 down under the arm and both grooves.
On hold bar 1 under the arm and hold under the arm down and place chalk in the groove of bar 2 and be used for writing letter written with chalk.In addition, hold bar 1 under the arm and hold under the arm down and can also paste one deck rubber in the groove of bar 2 and seize performance on both sides by the arms to improve it.The purpose that connecting plate 5 is set is to make pliers more flexible, no matter be meal pen or fine powder pen, this pliers can both be seized on both sides by the arms; No matter be that major part with chalk is placed on to hold under the arm in the bar or the microcephaly of chalk is placed on and holds under the arm in the bar, this pliers can both be seized on both sides by the arms.
