In order to more clearly illustrate the technical solution in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below. It is clear that the described figures represent only some embodiments of the invention, not all embodiments, and that a person skilled in the art can also derive other designs and figures from these figures without inventive effort.
Fig. 1 is a schematic diagram of the internal structure of the present invention.
In the drawings: 100-upper shell, 200-lower shell, 310-rolling ball, 320-baffle, 330-spring.
Detailed Description
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection relations mentioned herein do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Referring to fig. 1, the rubbing tool comprises an upper shell 100 and a lower shell 200 arranged at the bottom side of the upper shell 100, a containing cavity is formed between the upper shell 100 and the lower shell 200, a plurality of through holes are formed in the bottom surface of the lower shell 200, rolling balls 310 are arranged in the containing cavity corresponding to the through holes, the outer diameters of the rolling balls 310 are larger than the inner diameters of the through holes, and the bottoms of the rolling balls 310 extend out of the through holes to form rubbing portions.
By the aforesaid, it accomodates the cavity to form one between upper housing 100 and the lower housing 200, place a plurality of spin 310 in this accomodate cavity, and stretch out spin 310's bottom from casing 200's through-hole down, form the rubbing portion that is used for exerting pressure to the paper and rubs, when using, spin 310 is rotatable, and rub that the friction that forms between the rubbing face is rolling friction, greatly reduced and rubbing face between frictional force, make the paper be difficult to damage, and use more laborsaving, it is convenient, unnecessary time and physical demands in the rubbing manufacturing process have been reduced.
