Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, the present invention provides an eraser with iron oxide powder: including wiping body 1, recess 2, magnet 3, branch 4, draw-in groove 5 and revolve line 6, wipe 1 bottom front end of body and be provided with the recess 2 that can place article, 2 top sides of recess bond have magnet 3 that has the magnet function, 3 top sides four corners of magnet are welded with spacing branch 4 of using, 2 top sides four corners of recess are provided with the draw-in groove 5 that is used for fixed branch 4, the 4 outsides of branch are provided with the line 6 of revolving that can improve frictional force.

The edge around the wiping body 1 and the magnet 3 is arc-shaped, and the four corners of the inner side of the clamping groove 5 are provided with arc surfaces matched with the magnet 3, so that the comfort and the installation of the hand use are improved.

The iron oxide carbon powder is arranged in the raw materials of the wiper body 1, the number of the supporting rods 4 and the number of the clamping grooves 5 are 4, so that the generated scraps have iron oxide components, and the stability of the magnet 3 in the installation and placement of the groove 2 is improved.

The spiral lines 6 are of a protruding structure, the protruding height of each spiral line 6 is 0.5MM, and friction force between the support rod 4 and the clamping groove 5 is improved.

The thickness of the magnet 3 is consistent with the depth of the groove 2, and the length and the width of the magnet 3 are consistent with the length and the width of the groove 2, so that the magnet 3 can be stably installed in the groove 2 and keep the same horizontal plane.

Wherein, the surface of magnet 3 is the smooth surface, 4 lateral surfaces of branch are rough surface, improve the convenience of the piece clearance on magnet 3 and the steadiness that improvement branch 4 was placed.

The structure of the outer side of the support rod 4 is consistent with the structure of the inner side of the clamping groove 5, and the length of the support rod 4 is smaller than the depth of the clamping groove 5, so that the support rod 4 can be placed on the clamping groove 5 more stably.

The magnet 3 described in this patent is a magnet, and is a substance whose composition is an atom having a specific internal structure such as iron, cobalt, and nickel, and which itself has a magnetic moment, and can generate a magnetic field, and has a characteristic of attracting a ferromagnetic substance such as iron, nickel, and cobalt.

The working principle is as follows: when the iron stone eraser is used, the top of the inner side of the groove 2 is firstly coated with a super glue for bonding, then the tops of the support rods 4 on the four corners of the top side of the iron stone 3 are aligned with the clamping grooves 5 on the four corners of the inner side of the groove 2, so that the tops of the support rods 4 are inserted into the clamping grooves 5, the outer side of each support rod 4 has the same size as the inner side of the corresponding clamping groove 5, and the protruding spiral lines 6 arranged on the outer sides of the support rods 4 cause larger resistance when the support rods 4 are inserted, but the support rods 4 can extrude the inner walls of the clamping grooves 5 through the elastic effect of the material of the eraser body 1, so that the inner walls of the clamping grooves 5 slightly expand through the elastic effect, so that the support rods 4 can be stably inserted into the clamping grooves 5, the interiors of the clamping grooves 5 are restored through the elastic deformation, the support rods 4 are tightly attached to the support rods 4, the friction force between the outer sides of the support rods 4, because the structural specification of the outer side of the magnet 3 is consistent with the structural specification of the inner side of the groove 2, the resistance on the groove 2 is overlarge when the magnet 2 is installed, but through the same principle, after the groove 2 is inserted and installed in the magnet 3, the inner wall is expanded and deformed through elasticity, the top side of the magnet 3 is gradually and stably contacted with the strong glue coated on the top side of the groove 2, so that the magnet 3 can be fixed on the groove 2 through the strong glue and bonding, after the scraping body 1 generates scraps when in scraping, because the raw material of the scraping body 1 is provided with ferric oxide powder, the scraps generated by scraping are also provided with the ferric oxide powder, and then when the scraps need to be cleaned, the magnet 3 can be conveniently aligned to the scraps required to be cleaned, and the scraps containing the ferric oxide can be magnetically adsorbed through the characteristic that the magnet 3 can adsorb ferromagnetic substances, thereby collect the piece with concentrating and adsorb on magnet 3, treat to adsorb the completion back, clear up the garbage bin with it again on to light keep the desktop clean and tidy clean.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
