Plane grinding block tool

Abstract

A plane grinding block tool is provided; the bottom end face of a sponge core is covered by a sand layer; the top end face of the sponge core is provided with a hand plate; the end face, making contact with the sponge core, of the hand plate is provided with barbs; the surface, vertical to the top end face of the sponge core, of the hand plate is provided with round holes allowing fingers to pass; the horizontal cross section of the core is in a round shape, rectangular shape, triangle shape or n-shape; the sand layer is bonded with the sponge core; the hand plate and the sponge core are connected through the barbs or bonded; the grinding blocks of different shapes can be formed according to different requirements and demands; the grinding block and the hand plate are combined to formed grinding blocks of various shapes according to different requirements and demands; by using the hand plate, a user cannot feel unconformable by contacting the sand layer with hands in a long time; the hand plate is provided with round holes, so the hand can easily grab the hand plate, and the grinding block is more convenient in operation.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a flat sponge grinding block tool. Background technique [0002] As a new type of grinding material, sponge abrasive blocks are widely used in today's parts polishing and decoration. However, the existing sponge abrasive blocks all adopt the structure of bonding abrasive cloth on the surface of the sponge, and the shape and structure are single. More complex parts materials often cannot achieve the desired effect when grinding. Moreover, because the existing sponge grinding blocks basically need to be used by directly touching the frosted layer with hands, the long-term contact and friction between the hands and the frosted layer will cause hand damage. Discomfort affects the construction progress and construction quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flat sponge grinding block tool, which can be made into spon...
