(2) background technology:
At present, existing and once had about the demand of Multifunction teaching aid all being done very fruitful effort with the technology of additional plotting equipment jockey group, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Yang Songjie, Granted publication number is CN2243394Y, China Patent No. (ZL) is: No. 95224454.3 utility model patent title is the utility model patent of " that can return to zero rolls ", the technical scheme that is adopted.The technical elements of the additional plotting equipment jockey group of band is a routine of great value invention, but it has solved the technical problem of rolling set to zero effectively.But still have some deficits, it also is difficult to solve the big heaviness of normal blackboard compasses, avoids hand directly to contact with chalk, makes things convenient for the technical problem of usefulness.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of Multifunction teaching aid.To solve the big heaviness of normal blackboard compasses, avoid hand directly to contact with chalk, make things convenient for the technical problem of usefulness.
The Multifunction teaching aid that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: little rotating shaft, right half handle, right stretching bar, right telescopic head, right big rotating shaft, the big rotating shaft in a left side, Zola's boom, left telescopic head, left half handle, spring leaf, replaceable sleeve constitute.The little rotating shaft of its major part, right stretching bar, right telescopic head, right big rotating shaft, the big rotating shaft in a left side are selected for use by market.Its right side half handle is the hemicycle post shapes, is material with plastics, through the moulded section processing and manufacturing.Its left side half handle is the hemicycle post shapes, is material with plastics, through the moulded section processing and manufacturing.Its replaceable sleeve is the multidiameter shape, is material with plastics, through the moulded section processing and manufacturing.
In shape, structure and combination thereof, the total essential features of Multifunction teaching aid of the present utility model and immediate prior art is: an end position cover of right half handle is connected the axis body position of little rotating shaft, one end position cover of a left side half handle is connected the axis body position of little rotating shaft, be combined into the folding structure of the semi-cylindrical form that can change, function has been can work as the effect that compasses are used when two and half handles are closed.In shape, structure and combination thereof, the Multifunction teaching aid of the present utility model technical characterictic different with immediate prior art is: the indent cover position of left telescopic head is enclosed within the outer end position of right expansion link, the inner end positions cover of right expansion link is installed in the axis body position of right big rotating shaft, be combined into the stretching structure of cylindrical shape, function has been the effect of the length of expansion link.The interior recessed position of left side telescopic head is enclosed within the outer end position of left expansion link, and the inner end positions cover of left expansion link is installed in the axis body position of the big rotating shaft in a left side, is combined into the stretching structure of cylindrical shape, and function has been the effect of the length of expansion link.The nested end position that is connected left telescopic head of the interior location of spring leaf, the interior location card of spring leaf is installed and is connected the outer surface position of replaceable sleeve, but is combined into the separation structure of cylindrical shape, and function has been the effect that changes the function of telescopic head.So just realized the big heaviness of solution normal blackboard compasses of Multifunction teaching aid of the present utility model, avoided hand directly to contact, made things convenient for the purpose of the technical problem of usefulness with chalk.
The beneficial effect of the Multifunction teaching aid of utility model is: the utility model is for solving the big heaviness of normal blackboard compasses, avoid hand directly to contact with chalk, the technical scheme that technical problem adopted that makes things convenient for usefulness with existing with once had about having compared three advantages and improvement with the technology of additional plotting equipment jockey group:
First, because the indent cover position of having designed left telescopic head in the technical scheme of Multifunction teaching aid of the present utility model is enclosed within the outer end position of right expansion link, the inner end positions cover of right expansion link is installed in the axis body position of right big rotating shaft, be combined into the stretching structure of cylindrical shape, the interior recessed position of left side telescopic head is enclosed within the outer end position of left expansion link, the inner end positions cover of left side expansion link is installed in the axis body position of the big rotating shaft in a left side, be combined into the stretching structure of cylindrical shape, so the technical problem of length that can easier solution expansion link.
Second, owing to designed the nested end position that is connected left telescopic head of interior location of spring leaf in the technical scheme of Multifunction teaching aid of the present utility model, the interior location card of spring leaf is installed the outer surface position that is connected replaceable sleeve, but be combined into the separation structure of cylindrical shape, thus can be easier solution change the technical problem of the function of telescopic head.
