Abstract

A kind of marker used for English teaching, comprise at the bottom of left crossbeam, left handle, built-in beam, sliding beam, right crossbeam, right handle, spring, buckle, buckle, arrange left handle on the upside of described left crossbeam, left crossbeam side connects side by side parallel four built-in beams; Described built-in beam connects 3-8 successively and props up sliding beam, and the sliding beam of first paragraph is the sliding beam of head end, and the sliding beam of final stage is the sliding beam of end; Connected mode is that pull Antenna Type connects, and its sliding beam can free-extension; The sliding beam side by side parallel of described end, is connected with described right crossbeam; Arrange right handle above described right crossbeam, chalk is installed in right crossbeam lower end.The beneficial effects of the utility model are: be scribed ss straight straight line, and the spacing of line is even; Mode of operation is simple, rapid, improves efficiency of teaching; When not using, volume-diminished, easily carries and deposits.

Description

A kind of marker used for English teaching

Technical field

The utility model relates to a kind of teaching aid, especially a kind of marker used for English teaching.

Background technology

English teacher, in teaching process, often needs on blackboard, draw equidistant lines, and student is regular writes English alphabet or word for professor.Current English teacher mainly has three kinds of modes to complete line work: the first is by ruler to complete striping jobs, and this mode complicated operation, slowly, affects efficiency of teaching, and the spacing of the line drawn is uneven; The second is that four leveling rulers are parallel, and one end is fixed, and if Authorization Notice No. is the scriber for English teaching disclosed in the patent of CN203974331 U, although the line standard of comparison drawn like this, this scriber for English teaching volume ratio is comparatively large, is not easy to carry; The third handle is fixed the equal sleeve of four spacing, chalk or other type pen can be filled in sleeve, during line, manual moving handle, if Authorization Notice No. is the scriber for English teaching disclosed in the patent of CN 202413162 U, the line drawn like this, although spacing is equal, but easily crooked, there is curved arc.

Utility model content

The purpose of this utility model is to overcome above the deficiencies in the prior art, provides a kind of marker used for English teaching, and not only volume is light and handy, easily carries, can also draw the parallel lines that spacing is identical.

For solving the problem, the utility model adopts following technical scheme:

A kind of marker used for English teaching, comprises at the bottom of left crossbeam, left handle, built-in beam, sliding beam, right crossbeam, right handle, spring, buckle, buckle.Arrange left handle on the upside of described left crossbeam, left crossbeam side connects side by side parallel four built-in beams; Described built-in beam connects 3 one 8 sliding beams successively, and the sliding beam of first paragraph is the sliding beam of head end, and the sliding beam of final stage is the sliding beam of end; Connected mode is that pull Antenna Type connects, and its sliding beam can free-extension; The sliding beam side by side parallel of described end, is connected with described right crossbeam; Arrange right handle above described right crossbeam, chalk is installed in right crossbeam lower end.

As preferred technical scheme, described left crossbeam two ends arrange at the bottom of buckle, and described right crossbeam two ends arrange buckle, are buckled together at the bottom of buckle and buckle, marker used for English teaching during fixing compression.

As preferred technical scheme, described built-in beam and described sliding beam are conical tube, and inside arranges spring, and described spring left end is connected with left crossbeam, and right-hand member is connected with right crossbeam.

The beneficial effect of a kind of marker used for English teaching of the utility model is: be scribed ss straight straight line, and the spacing of line is even; Mode of operation is simple, rapid, improves efficiency of teaching; When not using, volume-diminished, easily carries and deposits.

Detailed description of the invention

Consult main TV structure schematic diagram when a kind of marker used for English teaching shown in Fig. 1 stretches, the A TV structure schematic diagram left of a kind of marker used for English teaching shown in Fig. 2, the left TV structure schematic diagram of a kind of marker used for English teaching shown in Fig. 3, to comprise at the bottom of left crossbeam 1, left handle 2, built-in beam 3, the sliding beam 4 of head end, the sliding beam 5 of end, right crossbeam 6, right handle 7, spring 8, sliding beam 9, buckle 10, buckle 11, arrange left handle 2 on the upside of described left crossbeam 1, described left crossbeam 1 side connects side by side parallel four built-in beams 3; Described built-in beam 3 connects the sliding beam 4 of head end, and the sliding beam 4 of head end connects the sliding beam 5 of end; Connected mode is that pull Antenna Type connects, and specifically sees Fig. 4, the syndeton schematic diagram between the built-in beam of a kind of marker used for English teaching of utility model and sliding beam or sliding beam; Sliding beam 5 side by side parallel of described end, is connected with described right crossbeam 6; Described right crossbeam 6 arranges right handle 7 above, and chalk 12 is installed in right crossbeam 6 lower end.

Described left crossbeam 1 two ends to arrange at the bottom of buckle 11, and described right crossbeam 6 two ends arrange buckle 10, and at the bottom of buckle 10 and buckle, 11 are buckled together, marker used for English teaching during fixing compression, as shown in Figure 5.

Described built-in beam 3 is conical tube with described sliding beam 9, and inside arranges spring 8, and described spring 8 left end is connected with left crossbeam 1, and right-hand member is connected with right crossbeam 6.

The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
