Description
technical field:
the utility model relates to a kind of economics classroom laser pointer.
background technology:
the teacher's pointer that current economic classroom uses can not Emission Lasers, during the indication blackboard content that is a teacher, and indication content is in blackboard eminence and the place that teacher's pointer can not touch, the classmate arranged after being in classroom is not easy to differentiate teacher's pointer indication region, directly uses laser instrument to carry out the content of courses and gives directions then serious not.
summary of the invention:
the purpose of this utility model is to provide a kind of economics classroom laser pointer.
above-mentioned object is realized by following technical scheme:
a kind of economics classroom laser pointer, its composition comprises: hand holding handle, described hand holding handle overcoat has antiskid glue sleeve, threaded line pipe is provided with above described hand holding handle, described threaded line pipe is built with wooden teacher's pointer, laser instrument cover described threaded line pipe is equipped with, described laser instrument cover side cover has laser bodies, battery pack is provided with in described laser bodies, described battery pack is built with a Battery pack, described battery is electrically connected with the switch in described laser bodies, and described laser bodies two ends are equipped with battery buckle closure and laser cover respectively.
described economics classroom laser pointer, is provided with limited step in the middle part of described hand holding handle; Described laser instrument cover comprises hand holding handle thread bush and laser instrument elastic sleeve, and described laser instrument elastic sleeve is provided with switch locating slot.
the beneficial effects of the utility model:
1. the utility model is provided with positioning step on hand holding handle, spacing and fixation can be played to antiskid glue sleeve and laser instrument cover, on the threaded line pipe that the hand holding handle thread bush that laser instrument overlaps can make laser instrument cover be screwed on hand holding handle, laser instrument can be clipped on laser instrument elastic sleeve, and the switch locating slot on laser instrument elastic sleeve can effectively prevent laser instrument from deflecting.
the utility model assume that generating laser on traditional teacher's pointer basis, the actual place touched can be difficult to teacher's pointer on laser pointers blackboard, the brightness of laser also makes to give directions position more obvious, allow classmate accurately can understand teacher's intention, make teaching effect in Teaching of Economics classroom better.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is laser instrument nested structure schematic diagram of the present utility model.
accompanying drawing 3 is left views of accompanying drawing 2.
