Abstract
The utility model relates to a transparency taking device for a projector combined by movable elements, which is especially suitable for taking and putting micro transparencies and is characterized in that two tweezer tips tilt up, and an upper tweezer tip end is provided with a concave block, and the lower tweezer tip fits with the groove of the concave block; table tops on two sides of the groove are provided with sticky paste. The utility model has the advantages of reasonable design, simple structure, flexible and convenient use, etc.
Description
The utility model relates to a kind of living-article combined projection sheet picture-taking device, and it is specially adapted to pick and place small lantern projectoring film.
In order to improve the quality of teaching, the inventor has gone out living-article combined type lantern projectoring film in conjunction with teaching material through research and design for many years.Though vivid good effect has played in this lantern projectoring film aspect teaching, but when picking and placeing small lantern projectoring film a difficult matter, promptly use tweezers to be difficult to its gripping, as not solving this difficult problem, living-article combined type lantern projectoring film just can not apply yet.
The purpose of this utility model is, in order to solve an above-mentioned difficult problem, provide a kind of reasonable in design, simple in structure, use flexibly, pick and place the handy picture-taking device of small lantern projectoring film.
Technical solution of the present utility model is, for small lantern projectoring film being taken away, and it is put accurately on the position, existing tweezers are improved, promptly the end of the tweezer point on be positioned at is provided with the spill piece, make to be positioned at following tweezer point and to match, and on the table top of groove both sides, be provided with the sticking cream of getting lantern slide for sticking with groove.Its sticking cream is medical rubber cream preferably.For the ease of using, two tweezer points to be pulled to the suitable angle that upwarps, the table top that makes the groove both sides is unilateral parallel with lantern projectoring film.
The utility model compared with the prior art, owing to be provided with the spill piece on the tweezer point on be positioned at, and on the table top of spill piece groove both sides, be provided with sticking cream, therefore it not only can glue small lantern projectoring film, and the quilt lantern projectoring film of having been glued can be by being pressed on the position that needs are put with the identical sharp resilience of tweezer of spill piece groove.Thereby solved the problem that picks and places small lantern projectoring film difficulty.
Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, the end of the tweezer point on be positioned at is fixed with the spill piece 2 that is made of copper by rivet.On the table top of spill piece 2 groove both sides, have groove, in groove, be extruded with sticking cream 3.Should sticking cream 3 be medical rubber cream.Being positioned at the following tweezer point and the groove of spill piece 2 matches.Two tweezer points up and down of tweezers 1 are pulled to the table top that makes spill piece groove both sides and the unilateral parallel position of lantern projectoring film.
During use, with finger tweezers are clamped, following tweezer point is entered in the groove of spill piece, and the sticking cream that passes through on the table top of spill piece groove both sides glues small lantern projectoring film, then small lantern projectoring film is transplanted on the required position of putting, unclamp after putting well tweezers make the resilience of following tweezer point with lantern projectoring film by being pressed on this position, simultaneously tweezers are lifted, make lantern projectoring film break away from tweezers, so just finished the work of fetching and delivering lantern slide.
