Abstract
The utility model relates to a three-lattice four-line scriber which consists of a measuring scale box, a free card, a pen card and a reset spring. The measuring scale box is a main support component of the three-lattice four-line scriber of the utility model, the measuring scale box is a long type square box and is hollow in the interior, the upper surface of the measuring scale box is provided with a sliding groove and a sliding groove which is wider than the upper surface is arranged on the lower surface of the measuring scale box. The free card is arranged at the interior of the measuring scale box and is blocked and connected in the sliding groove arranged at the upper surface of the measuring scale box by a handle, and the free card slides in the sliding groove arranged at the upper surface of the measuring scale box. The pen card is arranged in the free card and is used for installing chalks for drawing lines. The pen card passes through the interior of the handle of the free card and is provided with a hold-down handle in an upward extension way. The reset spring is arranged between the free card and the pen card. When the three-lattice four-line scriber of the utility model is used, the measuring scale box is attached on a blackboard, the hold-down handle on the pen card is pressed downwards and the free card is pulled at the same time, thereby being capable of drawing the standard three-lattice line on the blackboard. The three-lattice four-line scriber can be widely applied in the English and Chinese teachings. The three-lattice four-line scriber has the advantages of simple whole structure and convenient use.
Description
Technical field:
The utility model relates to teaching aid, relates in particular to a kind of three lattice, four line scribers.
Background technology:
In English or language teaching, teacher often will draw three rulings on blackboard now, generally all is to draw squares with ruler, divides four lines that draw for four times, and to form three lattice, such method for drafting is wasted time and energy, and four lines that draw and nonstandard.Chinese patent ZL 200420058885.2 discloses a kind of Pen for drawing four lines, alleviated the trouble of setting-out greatly, but, in the setting-out process, also needed to use ruler to draw squares because structure is too simple, and in the setting-out process, cause fractureing of chalk easily, use inconvenient.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of easy to use, the scriber of three lattice, four lines that can once draw.
Three lattice, four line scribers described in the utility model relate to by scale box, trip card, pen card and back-moving spring and forming.Said scale box is a wire support member of the present utility model, and the scale box is a microscler square box, inner hollow, and the upper surface of scale box is provided with chute, and lower surface is provided with the chute of being wider than upper surface.The inside of said scale box is provided with trip card, and said trip cartoon is crossed in the chute that handle is connected to scale box upper surface, slides in scale box upper surface chute.In the trip card, be provided with the pen card, be used for installing the chalk that setting-out is used.Said cartoon crossed the inside of trip card handle, extends upward and is provided with down pressure handle.Between trip card and pen card, be provided with back-moving spring.
When using three lattice, four line scribers described in the utility model, the scale box is affixed on the blackboard, presses down the following pressure handle on the pen card, the card of pulling trip simultaneously, three rulings of the standard of promptly can drawing on blackboard can be widely used in English, the language teaching.The utility model overall structure is simple, and is easy to use.
Description of drawings:
Accompanying drawing is the structural representation of three lattice, four line scribers described in the utility model.1-scale box 2-trip card 3-pen card 4-back-moving spring
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: three lattice, four line scribers described in the utility model relate to by scale box 1, trip card 2, pen card 3 and back-moving spring 4 and forming.Said scale box 1 is the wire support member of three lattice, four line scribers described in the utility model, and scale box 1 is a microscler square box, inner hollow, and the upper surface of scale box 1 is provided with chute, and lower surface is provided with the chute of being wider than upper surface.The inside of said scale box 1 is provided with trip card 2, and said trip card 2 is connected to by handle in the chute of scale box 1 upper surface, slides in scale box 1 upper surface chute.In trip card 2, be provided with pen card 3, be used for installing the chalk that setting-out is used.Said pen card 3 extends upward and is provided with down pressure handle by the inside of trip card handle.Between trip card 2 and pen card 3, be provided with back-moving spring 4.When using three lattice, four line scribers described in the utility model, scale box 1 is affixed on the blackboard, presses down the following pressure handle on the pen card 3, the card of pulling trip simultaneously 2, three rulings of the standard of promptly can drawing on blackboard can be widely used in English, the language teaching.The utility model overall structure is simple, and is easy to use.
