Adjusting rod be arranged in housing, rotation adjusting lever makes chalk lower end lean out 5-10mm from the holder of housing lower end, this
When, as the clamping part of holder is made up of elastomeric material, therefore clamping part will hold chalk tightly；Then on blackboard, mobile line is filled
Put, then can directly mark four lines, three lattice used that teach English, be additionally, since chalk connector end and be provided with spring, even if making
User exerts oneself uneven or blackboard situations such as slightly have uneven, and the elastic force of the spring also ensure that chalk is uniform on blackboard
Force so as to which the straight uniform for marking is attractive in appearance, and situations such as be not susceptible to chalk and rupture；After using a period of time, it is only necessary to again
Rotation adjusting lever, you can adjustment leans out the length of the chalk of holder；Be additionally, since this chalker user is caused without handss
Chalk is held, therefore can be allowed the user to substantially with complete root chalk or using flat using chalk using this chalker
When discarded chalk end of giving lessons reuse, so as to improve the utilization rate of chalk, economize on resources.
These technical schemes, including improved technical scheme and further improved technical scheme can also be combined with each other
Or combine, so as to reach superior technique effect.
There is following beneficial effect by adopting above-mentioned technical proposal, this utility model：
A kind of line-drawing device for English teaching of the present utility model be capable of fast and easy specification mark teach English it is used
Four lines, three lattice, and, can be allowed the user to substantially with complete root chalk using chalk using this chalker or
It is to be reused using discarded chalk end of giving lessons at ordinary times, so as to improve the utilization rate of chalk, economizes on resources.

Specific embodiment
Below in conjunction with the accompanying drawings this patent is further explained.But the protection domain of this patent is not limited to specific enforcement
Mode.
Embodiment 1
As illustrated, a kind of line-drawing device for English teaching of this patent, four are marked for the Express specification on blackboard
Three lattice of line, is characterized in that：Including body 1 and four chalk holders 2.
The vertical installing hole that body 1 is provided with four equidistantly and is parallel to each other；Chalk holder 2 includes housing 4, clamping
Part 5, adjusting rod 3, spring 8 and chalk connector 9；To set female cylindrical section, the cylindrical section lower end is provided with outer spiral shell to housing 4
Stricture of vagina；Holder 5 includes connecting portion 6 and clamping part 7；Connecting portion 6 is provided with female thread, outer spiral shell of the connecting portion 6 by cylindrical section lower end
Stricture of vagina connects housing 4；Clamping part 7 is made for elastomeric material and is provided with the circular platform type component of through hole；The clamping part 7 is worn for clamping
