Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, a portable light refraction experiment tool is designated as J2528, wherein the light refraction experiment tool comprises a refraction experiment mechanism detachably arranged on a base 1, a laser head 4 fixed on a mounting plate, and a battery pack 15 for supplying power to the laser head 4 through wires, wherein the refraction experiment mechanism comprises a measuring angle square 2, a frame 3, a placement table 5 and a lens 6, the measuring angle square 2 is foldable and inserted on the base 1 in a plug-in manner, the frame 3 is fixed on the measuring angle square 2 as shown in fig. 1, the placement table 5 is fixed on the base 1 below the centerline of the measuring angle square 2, the lens 6 is fixed on the placement table 5 for reflecting light passing through the frame 3, the above structure is not described in detail in the prior art, a placement box 10 for placing the battery pack 15 and a placement block 8 for placing the laser head 4 are fixedly connected on the base 1 on the rear side of the refraction experiment mechanism, the placement box 10 and the placement block 8 are mounted on the rear side of the measuring angle square 2, and the angle square 2 is not affected by the angle of the radiation or observation of the light on the front side of the refraction angle square 2.
