Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-5, the upper end of a kind of parallel line drawer for English teaching, including device block 1, device block 1 is equipped with four A device item 2, device item 2 is interior to be equipped with telescoping mechanism, and telescoping mechanism includes the cylindrical groove 10 being arranged in device item 2, cylinder The inner wall of shape slot 10 is fixedly connected with telescopic rod 3, and the end of telescopic rod 3 is fixedly connected with the inner wall of bar blocks 4, device block 1 Lower end is fixedly connected with magnetic stripe plate 11.

The right of device block 1 is equipped with bar blocks 4, and wiping board mechanism is equipped in bar blocks 4, and wiping board mechanism includes being arranged in item The inner wall of perforative square hole 8 in shape block 4, square hole 8 is equipped with groove 21, and the inner wall of square groove 8 slidably connects sliding block 7, sliding The both ends of block 7 are equipped with the supporting block 20 being slidably connected with groove 21, and supporting block 20 and the inner wall of groove 21 pass through the first spring 22 Elastic connection, the bottom end of sliding block 7 are fixedly connected with sponge wiping board 12.

The lower end of bar blocks 4 be equipped with sliding equipment, sliding equipment include be arranged in 4 lower end of bar blocks and be located at square hole Two square grooves 13 of 8 two sides, the inner wall of square groove 13 are fixedly connected with shaft 14, and shaft 14 slidably connects pulley 15

The upper end of bar blocks 4 is set there are four the round hole 6 for running through bar blocks 4, and the upper end of round hole 6 is equipped with corresponding side Shape block 5, the inside of square block 5, which is equipped with, pushes against mechanism, and pushing against mechanism includes the rectangular cavity 16 being arranged in square block 5, rectangular cavity 16 inner wall slidably connects wedge block 17, and one end of wedge block 17 and the inner wall of rectangular cavity 16 are connected by 18 elasticity of second spring It connects, the other end of wedge block 17 runs through the inner wall of rectangular cavity 16 and extends the side wall of square block 5, and the extension end of wedge block 17 is set There is gasket 19, the right end sidewalls of bar blocks 4 are fixedly connected with knob 9.

In the utility model, when using the present apparatus, device block 1 is adsorbed on the another of the required blackboard surface to draw lines first End makes bar blocks 4 against the place to be drawn lines, then four chalks is put into round hole 6, so that chalk is gently supported blackboard, so Wedge block 17 pushes against chalk under the action of second spring 18 afterwards, and the place then to draw lines to needs pulls knob 9, bar blocks 4 Pulley 15 in lower end square groove 13 starts turning, and telescopic rod 3 starts to stretch, and four chalks leave parallel lines on blackboard, when When painting line, it should be noted that cannot come loose knob 9 at once, it should slowly lift bar blocks 4, make telescopic rod 3 toward recycling until flexible Bar is taken in cylindrical groove completely, puts down bar blocks 4.When we are wrong in line drawing process, the wedge for the abutting that can come loose Shape block 17 up mentions chalk three or four centimetres, leaves blackboard surface, and pressing sliding block 7 at this time supports the sponge wiping board 12 of 7 lower end of sliding block Then firmly blackboard surface starts mobile bar blocks 4, sponge wiping board 12 is made to wipe the place of mistake, after wiped clean, unclamp and slide Block 7, sliding block 7 are restored to and 4 upper surface parallel position of bar blocks under the action of the first spring 22.
