Difference, and cause abrasive surface uneven, it is not used to the sanding and polishing of the higher equipment of surface accuracy, i.e., sponge substrate is hard
Degree is inadequate, structural instability.
In addition, people have used a variety of connection systems that the abrasive product of such as abrasive sheet and abrasive disc is connected to electric grinding mortar
Grinder tool, for example, sanding tool, so that the former be made to be driven by the latter.However, people prefer to using can directly removably
It is connected to abrasive product of the electric tool without operating the various machanical fasteners, i.e., cocoa is directly by abrasive product from hand
It is stripped down on dynamic or electric tool, without operating above-mentioned machanical fastener.Although secondly electric grinding tool can be great
The substitution manpower milling tool of cost performance, but higher cost, and under certain specific conditions, electric grinding tool is not available
(such as: without electricity or under the conditions of having a power failure), and when directly hand-held abrasive material polishes to substrate, it is easy that people is brought inconvenience or injured,
Therefore market needs a kind of hand-holdable, convenient, sponge sand device that can be easy to dismantle.
