Preferably, above-mentioned Novel English chalker, wherein said scriber comprises cuboid, and the front of described cuboid is provided with the through hole that four run through whole described cuboid in the horizontal direction, and the side of cuboid is respectively equipped with the fastening bolt be connected with each described through hole.
Preferably, above-mentioned Novel English chalker, the inner chamber of wherein said first cross bar is provided with riser, and output shaft and the described riser of the driven pulley of described helical gear pair are rotatably connected.
Preferably, above-mentioned Novel English chalker, the quantity of wherein said projection is two.
Preferably, above-mentioned Novel English chalker, the outer wall of wherein said second cross bar is provided with graduation mark.
Preferably, above-mentioned Novel English chalker, the bottom of wherein said blackboard body is provided with chalk holder.
Technique effect of the present utility model is mainly reflected in: user shakes rocking bar and drives helical gear pair to rotate, thus drive the 3rd cross bar to rotate, because projection is stuck in elongated slot, thus preventing the second cross bar to rotate together with the 3rd cross bar, the second cross bar can only move horizontally along elongated slot, thus band movable slider moves, adopt the length regulating drive unit in this way, easy to use, practical, and production cost is low; By regulating the length of drive unit to drive slide block to move, thus drive scriber line, it is high to adopt efficiency of ruling in this way.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1,2,3,4,5,6, a kind of Novel English chalker, comprises blackboard body 1, slide block 2, slide block 2 is connected with expansion link 9, expansion link 9 is connected with scriber 3, and the bottom of slide block 2 is provided with groove 21, and groove 21 is connected with the top slide of blackboard body 1.There is drive unit 5 at the top of blackboard body 1 by montant 4; Drive unit 5 comprises the first cross bar 51 of hollow, the second cross bar 52 of hollow, outer wall arrange threaded 3rd cross bar 53, helical gear pair 54, the rocking bar 55 be arranged in the first cross bar 51, the inwall of the first cross bar 51 is provided with two projections 56, the outer wall of the second cross bar 52 is provided with elongated slot 57 in the horizontal direction, inwall is provided with internal thread, one end of second cross bar 52 is inserted in the first cross bar 51 and projection 56 and elongated slot 57 are slidably connected, and the other end of the second cross bar 52 is connected with slide block 2; One end of 3rd cross bar 53 is connected with the output shaft of the driven pulley 90 of helical gear pair 54, the other end is inserted in the second cross bar 52 and the screw thread of the 3rd cross bar 53 is connected with the screw-internal thread fit of the second cross bar 52, and it is interior and be connected with the output shaft of the driving wheel 80 of helical gear pair 54 that a termination of rocking bar 55 is inserted into the first cross bar 51.
