As shown in Figures 1 to 4, a kind of Multi-functional English teaching board, including blackboard 1, the upper and lower ends of blackboard 1 are set respectively
There is an installing plate 11, the downside of installing plate 11 of the lower end of blackboard 1 is connected with support bar 12, and support bar 12 is installed on base,
Two the first symmetrical leads 111 are provided with installing plate 11, the picture that can be moved is provided with the first lead 111
Line apparatus 2, line-plotting device 2 include the mounting post 21 that can be slidably arranged on the first lead 111 and can movably set
Put the nib 3 in mounting post 21, mounting post 21 is provided with second lead 23 and a leading screw 22, and the one of mounting post 21
End is provided with the motor 24 for driving leading screw 22 to rotate, and the other end Screw assembly of mounting post 21 has clamping screw 211,
Clamping screw 211 is pushed against on the first lead 111；Nib 3 includes the sliding block being arranged on the lead 23 of leading screw 22 and second
31, the first screwed hole being engaged with leading screw 22 and be engaged with the second lead 23 first is offered on corresponding sliding block 31
Through hole, the center position of sliding block 31 offer chalk hole 311, and four equally distributed second are further opened with sliding block 31 and is led to
Hole, the second through hole is interior can be telescopically provided with the 3rd lead 35 by second spring 351, and the 3rd lead 35 is close to blackboard
1 end is fixedly installed the second pressing plate 33, and the other end of the 3rd lead 35 is provided with the first pressing plate 32, second spring 351
One end be pushed against on sliding block 31, the other end of second spring 351 is pushed against on the first pressing plate 32, is provided with the first pressing plate 32
Regulating bolt 321, offers the second screwed hole assembled for regulating bolt 321 on corresponding sliding block 31, on the second pressing plate 33
The internal diameter identical third through-hole 331 with chalk hole 311 is offered, the center position of the first pressing plate 32 opens up rectangular channel, powder
Adjustable column 34 can be telescopically provided with by the first spring 342 in hole 311, Screw assembly has adjustable plate on adjustable column 34
341, one end of the first spring 342 is fixedly installed on sliding block 31, and the other end of the first spring 342 is fixedly installed on adjustable plate
On 341；The end set close to the first pressing plate 32 in chalk hole 311 has the flexible catch 312 that several are uniformly distributed circumferentially,

Inwall.
Wherein, support bar 12 is expansion link.Felt is provided with the surface of the close blackboard 1 of second pressing plate 33.
In use, chalk is put into chalk hole 311 by teacher, according to the length adjustment adjustable column 34 of chalk in adjustable plate
The amount of screwing on 341, ensure that chalk produces enough pressure to blackboard 1 so that setting-out becomes apparent from, and teacher is according between setting-out
Position away from adjustment nib 3, subsequent start-up motor 24 can carry out striping jobs, in chalk gradually using the process to shorten
In, whether teacher needs to increase the length goed deep into chalk hole 311 of adjustable column 34 according to the definition judgment of chalk setting-out, and then
Ensure that chalk persistently produces pressure to blackboard 1, making up chalk, length gradually decreases and causes chalk can not be in use
On blackboard 1 the defects of setting-out, chalk is avoided can not be used in the case of shorter the problem of；When needing erasing, will adjust
In the precession sliding block 31 of bolt 321, the second pressing plate 33 is compressed blackboard 1, while pull adjustable column 34, adjustable column 34 is departed from chalk
Hole 311, its pressure to chalk is released, prevent from carrying out setting-out during erasing, subsequent start-up motor 24, and adjust
The erasing to blackboard 1 is realized in position of the line-plotting device 2 on the first lead 111, in addition after adjustable column 34 departs from chalk hole,
Flexible catch 312 in chalk hole 311 can prevent chalk from dropping.
The present invention is simple to operate, has setting-out and erasing function, need to only adjust line-plotting device in the first lead during use
On position can draw a plurality of straight line, the adjustable plate and adjustable column in nib compensate for chalk, and length is gradual in use
Reduce and cause chalk can not be the setting-out on blackboard the defects of, while the setting of the second pressing plate and the first pressing plate greatly facilitates
Erasing to lines, pressure of second pressing plate to blackboard can easily be adjusted by regulating bolt, so as to realize to blackboard
Erasing, the in addition setting of regulating bolt cause setting-out not interfere with each other with erasing, greatly facilitate the use of teacher.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these changes and modification.
