Abstract

The utility model relates to an English teaching tool. The English teaching tool comprises a base plate, a chalk clamp and an eraser fixator, wherein four parallel grooves are formed in the base plate; four chalk clamping holes are formed in the chalk clamp and arranged in one-to-one correspondence with the four grooves, a first end of the chalk clamp is in sliding connection with the upper end face of the base plate, and a second end of the chalk clamp is in sliding connection with the lower end face of the base plate; the eraser fixator comprises a fixing plate and four erasers, the fixing plate and the erasers are fixedly connected, the four erasers are inserted in the four grooves in a one-to-one correspondence mode, a first end of the fixing plate is in sliding connection with the upper end face of the base plate, and a second end of the fixing plate is in sliding connection with the lower end face of the base plate. According to the English teaching tool, four-line three squares can be drawn once through the chalk clamp and erased by the eraser fixator, and the English teaching tool is quite convenient to use. The English teaching tool has the advantages of being simple in structure, low in cost and convenient to operate.

Description

The English teaching instrument

Technical field

The utility model relates to the English teaching field of tool, particularly relates to a kind of English teaching instrument.

Background technology

When English teaching, sometimes need to mark four line three lattice on blackboard, in order to write in prior art.At this moment, the teacher adopts free-hand mode to rule usually, has problem time-consuming, effort.

The utility model content

The purpose of this utility model be to provide a kind of simple in structure, cost is low, easy to operate, the English teaching instrument that can rule, can wipe at any time again.

For solving the problems of the technologies described above,, as an aspect of the present utility model, provide a kind of English teaching instrument, comprising: substrate offers four grooves that are parallel to each other on substrate; Chalk holder, offer four chalk clamping holes on chalk holder, four chalk clamping holes and four grooves arrange correspondingly; The first end of chalk holder and the upper surface of substrate are slidably connected, and the second end of chalk holder and the lower surface of substrate are slidably connected; The blackboard eraser fixator, the blackboard eraser fixator comprises fixed head and four blackboard erasers, and blackboard eraser is fixedly connected with fixed head, and four blackboard erasers insert in four grooves correspondingly, the first end of fixed head and the upper surface of substrate are slidably connected, and the second end of fixed head and the lower surface of substrate are slidably connected.

Further, offer the first chute on upper surface, the first end of chalk holder is fixedly installed the first fixture block, and the first fixture block inserts the first chute; The first end of fixed head is provided with the second fixture block, and the second fixture block inserts the first chute.

Further, offer the second chute on lower surface, the second end of chalk holder is fixedly installed the 3rd fixture block, and the 3rd fixture block inserts the second chute; The second end of fixed head is provided with the 4th fixture block, and the 4th fixture block inserts the second chute.

The utility model can utilize the disposable drafting of completing four line three lattice of its chalk holder, simultaneously, also can utilize the blackboard eraser fixator to wipe, and is very convenient to use, has characteristics simple in structure, that cost is low, easy to operate.

The specific embodiment

Below embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Please refer to Fig. 1 to Fig. 4, the utility model provides a kind of English teaching instrument, comprising: substrate 1 offers four grooves that are parallel to each other 4 on substrate 1; Chalk holder 2, offer 3, four chalk clamping holes 3 of four chalk clamping holes on chalk holder 2 and four grooves 4 arrange correspondingly; The upper surface of the first end of chalk holder 2 and substrate 1 is slidably connected, and the second end of chalk holder 2 and the lower surface of substrate 1 are slidably connected; Blackboard eraser fixator 5, blackboard eraser fixator 5 comprises fixed head 6 and four blackboard erasers 7, blackboard eraser 7 is fixedly connected with fixed head 6, and four blackboard erasers 7 insert in four grooves 4 correspondingly, the upper surface of the first end of fixed head 6 and substrate 1 is slidably connected, and the second end of fixed head 6 and the lower surface of substrate 1 are slidably connected.

Preferably, offer the first chute 9 on upper surface, the first end of chalk holder 2 is fixedly installed the first fixture block 8, the first fixture blocks 8 and inserts the first chute 9; The first end of fixed head 6 is provided with the second fixture block 10, the second fixture blocks 10 and inserts the first chute 9.

Preferably, offer the second chute on lower surface, the second end of chalk holder 2 is fixedly installed the 3rd fixture block 11, the three fixture blocks 11 and inserts the second chute; The second end of fixed head 6 is provided with the 4th fixture block 12, the four fixture blocks 12 and inserts the second chute.

During use, chalk is inserted in the chalk clamping hole 3 of chalk holder 2, thereby chalk is fixed on chalk holder 2.Then, with hand, chalk holder 2 is moved to right-hand member from the left end of Fig. 1, so, just can be on blackboard once property complete the drafting of four line three lattice.As find mistake in drawing process, the blackboard eraser fixator 5 on right side can be moved to the left, thereby wipe corresponding part, very convenient to use, have characteristics simple in structure, that cost is low, easy to operate.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
