Abstract

The utility model discloses a multifunctional scribing tool comprising a main board. A flat board is disposed at the front of the main board, and a handle integrated to the flat board is arranged at the rear of the main board. A plurality of chalk sleeves for accommodating chalks are arranged at the front of the flat board at intervals. A guide caliper is slidably connected to the rear of the flat board. The chalks can be disposed in the chalk sleeves at the front of the main board respectively. The number of the chalks to be mounted is determined according to the number of lines to be drawn. The guide caliper is slidably connected with the main board. The guide caliper guarantees parallelism of the lines. The positions of the lines on a chalkboard can be determined by adjusting the position of the main board on the guide caliper and fixing a single-side clamp to the main board, and then a plurality of parallel lines can be drawn by moving the main board; work efficiency is high, and learning time is saved; the multifunctional scribing tool is simple in structure and convenient to use.

Multifunction picture the Line tool

Technical field

The utility model relates to a kind of multifunction picture the Line tool.

Background technology

In music and the English class, teacher is in order to make more standard of staff writing on the blackboard more attractive in appearance, English, usually need draw three four lines or four five lines at blackboard, in the setting-out process, the depth of parallelism of lines is difficult to hold, and the teacher need make auxiliary of ruler,, the picture of a line of line, difficulty is bigger, increases teacher's labour intensity, and waste student's learning time.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned defective, and multifunction picture the Line tool of a kind of many parallel lines that can draw simultaneously is provided.

In order to solve the problems of the technologies described above, the utility model provides a kind of multifunction picture the Line tool with following structure, its design feature is to comprise mainboard, the front portion of described mainboard is provided with flat board, the rear portion is provided with and the integrated handle of flat board, the front portion of described flat board is interval with a plurality of chalk sleeves of placing chalk, and the rear portion of described flat board slidely connects the guiding slide calliper rule.

The both sides, rear portion of described flat board are connected with respectively can be with the locking device of guiding slide calliper rule locking.

Described locking device is two single-sided clamps that are disposed on the mainboard.

The Handheld Division of described two single-sided clamps connects as one.

Described guiding slide calliper rule are provided with scale.

Adopt multifunction picture the Line tool of such scheme compared with prior art to have the following advantages: in the chalk sleeve of mainboard front portion chalk can be installed respectively, the corresponding chalk number of installing of bar number according to required setting-out, guiding slide calliper rule and mainboard are slidingly connected, the guiding slide calliper rule are that mainboard play the guiding role, can guarantee the depth of parallelism of lines, regulate the position of mainboard on the guiding slide calliper rule, and be fixed on the mainboard by single-sided clamp, determine the position of lines on blackboard, mobile mainboard many parallel lines that can draw simultaneously, high efficiency is saved learning time, and it is simple in structure, easy to use.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the annexation figure of guiding slide calliper rule and blackboard.

The specific embodiment

With reference to accompanying drawing 2, existing blackboard generally is provided with groove 6 in the bottom of blackboard 8, conveniently deposits educational aids such as chalk, blackboard eraser, and the top of some blackboard is provided with top cover 7.This multifunction picture the Line tool comprises mainboard 1 as shown in Figure 1, the front portion of described mainboard 1 is provided with dull and stereotyped 11, the rear portion is provided with and dull and stereotyped 11 integrated handles 12, described dull and stereotyped 11 front portion is interval with a plurality of chalk sleeves 2 of placing chalk, distance between adjacent two chalk sleeves 2 equals the distance between two lines in standard four lines three lattice, described dull and stereotyped 11 rear portion slidely connects guiding slide calliper rule 3, can arrange and guiding slide calliper rule 3 corresponding groove dull and stereotyped 11, the slide calliper rule 3 that will lead snap fitted in the groove, guarantee not double swerve of guiding slide calliper rule 3, the length of guiding slide calliper rule 3 is identical with the height of blackboard 8, the upper end of guiding slide calliper rule 3 leans in the top cover 7 of blackboard 8, the lower end of guiding slide calliper rule 3 leans in the groove 6 of blackboard 8, guiding slide calliper rule 3 can guarantee the glacing flatness of setting-out for the movement of mainboard 1 play the guiding role.Described guiding slide calliper rule 3 are provided with scale 5, but subsidiary or definite setting-out position.Dull and stereotyped 11 rearward end both sides are connected with respectively can be with the locking device of guiding slide calliper rule 3 lockings, described locking device is two single-sided clamps 4 that are disposed on the mainboard 1, distance is less between two single-sided clamps 4, the Handheld Division of two single-sided clamps 4 connects as one, a Handheld Division can be controlled two single-sided clamps 4 simultaneously, and is easy to operate.

Slide calliper rule 3 vertical card that at first will lead during use install in the last bottom of blackboard, position slip mainboard 1 according to required setting-out, mainboard 1 is determined behind the position on the guiding slide calliper rule 3, be fixed on the mainboard 1 by single-sided clamp 4 slide calliper rule 3 that will lead, according to the required number installation chalks chalk sleeve 2 in that draw lines, hold handle 12 move mainboard 1 just can be at the blackboard respective parallel line lattice that draw.The utility model is simple in structure, and is easy to use, reduces teaching job intensity, saves student's learning time.
