Description
Technical field
the utility model relates to a kind of English teaching parallel lines producing device.
Background technology
need picture much to write the parallel lines of English letter and word when taking lessons in English, but if only draw with hand, to see with eyes and be difficult to draw the straight line be parallel to each other, the English alphabet write out in the uneven situation of lines be also crooked very unsightly.
Summary of the invention
the purpose of this utility model is to provide a kind of English teaching parallel lines producing device that disposablely can draw many straight lines be parallel to each other, can write out beautiful English letter.
above-mentioned object is realized by following technical scheme:
a kind of English teaching parallel lines producing device, its composition comprises: link plate, the top of described link plate has upper trapezoid inserting groove, described upper trapezoid inserting groove connects trapezoidal upper cutting, described trapezoidal upper cutting connects upper side plate, the bottom of described link plate has lower trapezoid inserting groove, and described lower trapezoid inserting groove connects trapezoidal lower cutting, and described trapezoidal lower cutting connects lower side plate; Described upper side plate has inverted T-shaped upper hopper chute, described lower side plate has inverted T-shaped gliding groove, described inverted T-shaped upper hopper chute connects inverted T-shaped top shoe, described inverted T-shaped gliding groove connects inverted T-shaped sliding block, be connected by strain plate between described inverted T-shaped top shoe and described inverted T-shaped sliding block, described strain plate has one group of through hole, every 4 of described through hole is one group, often the spacing of group is equal, the spacing of the through hole described in 4 is equal, and described through hole connects penholder fastener or chalk fastener.
described English teaching parallel lines producing device, described penholder fastener or described chalk fastener include elastic opening cover, described elastic opening cover clamping penholder or chalk, one end of described elastic opening cover connects bracket, the other end of described elastic opening cover connects magnetic sheet, described bracket connects one group of magnetic sheet, described bracket is connected and fixed penholder or chalk by described magnetic sheet adhesive, inserts described through hole and rule after described elastic opening cover is fixing.
described English teaching parallel lines producing device, the left side of described strain plate connects Zola's hand, the right side of described strain plate connects right handle, left part and the right part of described upper side plate all have upper screwed hole, left part and the right part of described lower side plate all have lower screwed hole, described upper screwed hole and the described equal connecting screw rod of lower screwed hole, described screw rod connects knob, described screw rod is each passed through right baffle-plate and right baffle plate, top and the bottom of described right baffle-plate and described right baffle plate all have circular hole, described screw rod is through described circular hole.
beneficial effect:
1. the inverted T-shaped top shoe that adopts of the utility model and inverted T-shaped sliding block drive strain plate horizontally slipping along link plate, can draw often to organize that to be all 4 straight lines be parallel to each other write English primary and secondary or word or sentence for the English class simultaneously.
point-blank, the straight line drawn by chalk is that English alphabet that be parallel to each other, that write out, word, sentence are attractive in appearance, beautiful to the through hole that the utility model adopts.
the elastic opening cover that the utility model adopts is fixed by bracket and magnetic sheet, fixing chalk or line penholder effective, stable.
the right baffle-plate that the utility model adopts and right baffle plate can block strain plate and not skid off upper trapezoid inserting groove and lower trapezoid inserting groove, use safety.
accompanying drawing illustrates:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is right views of accompanying drawing 1.
accompanying drawing 3 is partial enlarged drawings of accompanying drawing 2.
