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.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

The utility model provides a tool for grinding experimental materials, which is shown in fig. 1-3, and comprises a mortar 1 and a grinding rod 2, wherein a plurality of strip-shaped first bulges 11 are arranged on the inner wall of the mortar 1, the first bulges 11 are in an annular or ring-lacking structure, and the first bulges 11 are sequentially arranged at intervals from the bottom of the mortar 1 to an opening of the mortar 1; the grinding rod 2 comprises a handle 23 and a head 21, and in use, the surface of the head 21 grinds against the inner wall of the mortar 1, the head 21 of the grinding rod 2 being provided with a second protrusion 22 in the form of a strip.

The mortar 1 is preferably integrally formed with the first protrusions 11, the grinding rod 2, and the second protrusions 22.

According to the utility model, the first bulge 11 is arranged on the inner wall of the mortar 1, the second bulge 22 is arranged on the head 21 of the grinding rod 2, and during grinding, the shearing force generated by friction between the second bulge 22 and the first bulge 11 is used for shearing and grinding materials with larger toughness, so that the grinding effect and efficiency are improved, and the second bulge 22 and the first bulge 11 are not easy to wear and are suitable for long-term use, so that the purposes of time and labor saving and high efficiency can be achieved.
