Abstract

The invention discloses a kind of Novel chalk clamp, including finger sleeve ring and chalk clamp, wherein, finger ring set is circular ring, the side of finger sleeve ring is provided with chalk clamp, chalk clamp includes sleeve and elastic clamping piece, and sleeve is above inner hollow and the following cylindrical-shaped structure being open, the bottom surrounding of sleeve are provided with the elastic clamping piece of strip；It is total, the present invention have it is simple in construction, easy to use, the advantages of branched chalk can be clamped simultaneously.

Description

A kind of Novel chalk clamp

Technical field

The invention belongs to school supply and stationery field, and in particular to a kind of Novel chalk clamp.

Background technology

The composition of chalk is a kind of white depositions of calcium sulfate, it is not easy to is decomposed, particle is bigger than dust, general multi-purpose Write in teaching on blackboard, existing chalk is mostly common chalk, common chalk using when chalk dust be easier to disperse, The chalk dust pollution in classroom can be than more serious, and when chalk has used soon, chalk end is shorter to be not easy to hold, generally all It can directly be dropped, easily cause physical waste；On the other hand, existing related chalk clamp solves the above problems, existing chalk clamp Mostly single-cylinder type, piece of chalk can only be once clamped, and need to use a variety of different colours chalks when some classrooms are given lessons, to this Need to use more chalk clamps, be inconvenient.

To this, there is a kind of chalk clamp device, including Handheld Division and chalk clamp, chalk clamp includes upper clamp, set Put the holes one of the both sides on upper clamp, lower clamp, the hole two for being arranged on both sides on lower clamp, the card for being arranged on lower clamp bottom Block, spring and axis body, spring are arranged between upper clamp and lower clamp, and one end is connected with upper clamp, and the other end connects with lower clamp Connect, axis body connects upper clamp and lower clamp through hole one, hole two and spring, and chalk clamp is carried by fixture block and neck and hand Hold portion's combination；Although this structure solves the problems, such as that branched chalk can not be clamped, but following defect be present：First, it is described Chalk clamp direction down, while be distributed in the surrounding of Handheld Division, so not only write not specifically used when It is convenient, and be not easy to hold；Secondly, chalk clamp connects the effect for realizing clamping using upper lower clamp by spring, this Kind structure is not easy to adjust the length of chalk when in use, is inconvenient.

So to solve the above problems, to develop a kind of Novel chalk clamp necessary.

The content of the invention

The invention aims to overcome the deficiencies in the prior art, and offer one kind is simple in construction, easy to use, can press from both sides Hold the Novel chalk clamp of branched chalk.

The object of the present invention is achieved like this：A kind of Novel chalk clamp, including finger sleeve ring and chalk clamp, wherein, it is described Finger ring set is circular ring, and the side of the finger sleeve ring is provided with the chalk clamp, and the chalk clamp includes sleeve and elasticity Clamp clip, the sleeve is above inner hollow and the following cylindrical-shaped structure being open, the bottom surrounding of the sleeve are set It is equipped with the elastic clamping piece of strip.

The chalk clamp at least two.

Two chalk clamps are in opposite direction.

The finger sleeve ring and the chalk clamp are integral type structure.

By adopting the above-described technical solution, the beneficial effects of the invention are as follows：

（1）The setting of branched chalk clamp, branched chalk can be clamped simultaneously, need to only take chalk clamp when in use, it is not necessary to Replaced back and forth by branched chalk, it is easy to use；

（2）The setting of finger sleeve ring, when in use, forefinger is inserted in finger sleeve ring, it is more convenient to hold, using also more Flexibly；

（3）The setting that elasticity steps up piece makes the gripping of chalk more convenient easy, while is also convenient for adjusting the position of chalk and makes Use length.

Brief description of the drawings

Fig. 1 is the dimensional structure diagram of the present invention.

Fig. 2 is the dimensional structure diagram of the embodiment of the present invention.

In figure：1st, finger sleeve ring 2, chalk clamp 3, sleeve 4, elastic clamping piece.

Embodiment

Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.

As shown in figure 1, a kind of Novel chalk clamp, including finger sleeve ring 1 and chalk clamp 2.

Wherein, finger ring set 1 is circular ring, and the side of finger sleeve ring 1 is provided with chalk clamp 2, while by finger sleeve ring 1 and powder Pen clip 2 is arranged to integral structure, can so make total more durable, and chalk clamp 2 includes sleeve 3 and elastic clip Tight piece 4, sleeve 3 is above inner hollow and the following cylindrical-shaped structure being open, the bottom surrounding of sleeve 3 are provided with strip Elastic clamping piece 4, chalk clamp 2 at least two, it is preferred that two chalk clamps 2 are in opposite direction, more square when writing Just.

For the present invention when it is implemented, chalk is inserted in chalk clamp 2, elastic clip 4 clamps chalk, and chalk is adjusted to conjunction Suitable writing length, forefinger is inserted in finger sleeve ring 1, in use, finger pinches sleeve 3, can arbitrarily adjust chalk length, simultaneously Also branched chalk can be clamped, hand is not directly contacted with chalk, effectively can prevent chalk dust from sticking on hand.

Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations, although The present invention is described in detail with reference to above-described embodiment, it should be understood by a person of ordinary skill in the art that still may be used Modified or equivalent substitution with the embodiment to the present invention, and repaiied without departing from any of spirit and scope of the invention Change or equivalent substitution, it all should cover among scope of the presently claimed invention.
