Abstract
The utility model provides a four-line three-lattice scriber, belonging to the field of teaching tools. The four-line three-lattice scriber comprises a positioning body and a ruler, wherein a chute is arranged at the right part inside the positioning body and internally provided with a sliding block matched with the chute; a movable groove is arranged at the middle part of the sliding block; an upright column is vertically arranged inside the movable groove and articulated with the bottom of the movable groove; a spring is arranged at the right end of the upright column and the movable groove, namely inside the movable groove; the upper end of the upright column passes though a slideway arranged on the upper surface of the positioning boy to be subsequently articulated with a knob; a positioning hole is arranged at the left side of the slideway and communicated with the slideway; a positioning plate is arranged at the right end of the sliding block and fixedly connected with the sliding block; the positioning plate leans against the right end of the positioning body and is connected with the positioning body in a sliding way; and the ruler is arranged at the right end of the positioning plate. Compared with the prior art, the utility model has the characteristics that the four-line three-lattice scriber has reasonable design and simple structure, is convenient to use, can improve teaching efficiency, etc.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of four lines, three lattice scribers.
Background technology
When taking lessons in English, for expressing the specification writing of letter, four lines, three lattice usually need draw on blackboard; Do not have good apparatus and draw four lines, three lattice, usually all be teacher's drawing with a horizontal line of horizontal line of ruler, owing to be manually-operated, not only the depth of parallelism between the horizontal line can't guarantee, and the distance between the horizontal line can not well be held, four lines, three lattice of Hui Zhiing are very nonstandard like this, can't reach the expection requirement to the expression of normalized written.
Summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of four lines, three lattice scribers reasonable in design, simple in structure are provided.
The technical scheme that its technical problem that solves the utility model adopts is: comprise positioning body and ruler, right part offers sliding tray in the described positioning body, be provided with sliding shoe in the sliding tray and match with it, described sliding shoe middle part is provided with loose slot, vertically be provided with in the loose slot column and with its bottom be hinged, column and loose slot right-hand member are to be provided with spring in the loose slot, column upper end is hinged with knob after passing the slideway of positioning body upper surface setting again, and the slideway left side is provided with locating hole and coupled logical; The sliding shoe right-hand member is provided with location-plate and fixedlys connected with it, and location-plate leans against on the positioning body right-hand member and with it and is slidingly connected, and described ruler is arranged on the location-plate right-hand member.
Vertical setting between ruler and the positioning body.
Locating hole is provided with four and arrange to be provided with by certain distance.
Hand pinches knob, and movable ruler is moved to the top, unclamps knob, just can be moved to the left along loose slot under acting force of the spring when column arrives first locating hole, and column is parked in the locating hole, and straight line draws on ruler this moment; Promote knob to the right, and sliding shoe is driven ruler, again can be when column arrives second locating hole because of acting force of the spring enter in the locating hole, the second straight line that draws again thus, and the like.
A kind of four lines, three lattice scribers of the present utility model compared with prior art, the beneficial effect that is produced is:
1, can draw four lines, three lattice very easily, draw comparatively ideal of effect, help the raising of efficiency of teaching.
2, have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, thereby have excellent popularization and use prospect.
