Description
Technical field
The utility model relates to a kind of English teaching device, especially a kind of scriber for English language teaching.
Background technology
In English teaching, in order to make letter writing standardization, often need on blackboard, draw four line three lattice, but in existing scriber, the distance between pen clip device is all nonadjustable, is not easy to the teaching of teacher.
Summary of the invention
Technical assignment of the present utility model is for above the deficiencies in the prior art, and provides a kind of scriber for English language teaching.
The utility model solves the technical scheme that its technical problem adopts: a kind of scriber for English language teaching, comprise back-up block and pen clip device, wherein in described back-up block, be provided with chute, four slide blocks are provided with in described chute, four described slide blocks are provided with described pen clip device, between described slide block, be provided with telescopic arm, described telescopic arm is connected with Control Component.
Described Control Component is hydraulic cylinder, catheter is provided with at described hydraulic cylinder end, piston is provided with in described hydraulic cylinder, described piston is provided with connecting rod, adjusting knob is provided with on described connecting rod top, the outer wall of described adjusting knob and described hydraulic cylinder is threaded connection, and described telescopic arm is hydraulic telescopic arm, and described catheter is connected with the inlet place of described hydraulic telescopic arm.
Advantage of the present utility model: according to hydraulicdriven principle, moving up and down of control piston is carried out by rotating adjusting knob, then thrust-neutral piston produced by the effect of catheter assign on each hydraulic telescopic arm, so just achieve the adjustment to pen clip device spacing, use simple and convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As shown in the figure, a kind of scriber for English language teaching, comprise back-up block 1 and pen clip device 5, wherein in described back-up block 1, be provided with chute 2, four slide blocks 3 are provided with in described chute 2, four described slide blocks 3 are provided with described pen clip device 5, and between described slide block 3, be provided with telescopic arm, described telescopic arm is connected with Control Component.
Described Control Component is hydraulic cylinder 7, catheter 6 is provided with at described hydraulic cylinder 7 end, piston 8 is provided with in described hydraulic cylinder 7, described piston 8 is provided with connecting rod 9, adjusting knob 10 is provided with on described connecting rod 9 top, described adjusting knob 10 is threaded connection with the outer wall of described hydraulic cylinder 7, and described telescopic arm is hydraulic telescopic arm 4, and described catheter 6 is connected with the inlet place of described hydraulic telescopic arm 4.
Its operation principle is: because adjusting knob 10 is threaded connection with the outer wall of hydraulic cylinder 7, so when rotating adjusting knob 10, connecting rod 9 will drive piston 8 downwards or move up, when piston 8 moves down, liquid in hydraulic cylinder 7 flows in hydraulic telescopic arm 4 by catheter 6, hydraulic telescopic arm 4 is caused to start to extend, distance between such slide block 3 will become large, pressure when piston 8 moves up bottom hydraulic cylinder 7 reduces, liquid in hydraulic telescopic arm is back in hydraulic cylinder 7 by catheter 6, the distance between slide block 3 is finally made to reduce, this process operation is simple and convenient, only need by rotate adjusting knob 10 just can to realize pen clip device 5 between distance controlling.
