Further, the wiper strip 70 is provided on the second and fourth shell portions 112 and 212 at the positions of the wiping surfaces 1121 and 2121. When the first wiping body 10 and the second wiping body 20 clean the object to be wiped, water stains on the surface of the object to be wiped can be scraped off by the scraping strip 70.

Referring to fig. 4, in an embodiment, the second wiping body 20 is further provided with a water outlet 80 at a position where the wiping cloth 60 is provided, and the water outlet 80 is communicated with a water pipe 90, so that liquid can flow out from the water outlet 80, and dirt on the surface of the object to be wiped can be more easily removed after the wiping cloth 60 is wetted during cleaning.

Referring to fig. 5, when the double-sided eraser 100 is used to clean an object to be erased, the working process is as follows:

the first wiping body 10 and the second wiping body 20 which are absorbed together are separated, and the first wiping body 10 and the second wiping body 20 are positioned on two opposite surfaces of the object to be wiped. For example, when cleaning glass, the second wiper 20 is provided on the outer surface of the glass, and the first wiper 10 is provided on the inner surface of the glass. After the contact point 321 on the rotating member 32 of the anti-pinch mechanism 30 contacts the glass surface and is pressed, the rotating member 32 rotates and retracts into the first wiping body 10, and the elastic member 33 is compressed until the wiping surface 1121 of the first wiping body 10 and the wiper 60 contact the glass surface.

By the attraction of the magnetic attraction mechanism 40, the first wiping body 10 moves and the second wiping body 20 moves along with the first wiping body 10. Because liquid exists on the glass surface, the adsorption piece 22 slides smoothly along the glass surface, so that the second wiping body 20 can move on the glass surface.

When the first wiper 10 and the second wiper 20 are separated from the glass after the glass is cleaned, the rotating member 32 of the anti-pinch mechanism 30 is protruded from the first wiper 10 by the elastic force provided by the elastic member 33. After the first wiper 10 and the second wiper 20 are aligned, they are attracted to each other, and the contact 321 of the rotating element 32 is received in the groove 2123. The friction force between the rotating piece 32 and the second wiper 20 and the elastic force provided by the elastic piece 33 to the rotating piece 32 enable the rotating piece 32 to overcome the adsorption force and to be abutted between the first wiper 10 and the second wiper 20. A gap exists between the first wiping body 10 and the second wiping body 20, so that the first wiping body and the second wiping body can be conveniently separated, and the hands of a user can not be clamped in the process of mutual adsorption.

Second embodiment

Referring to fig. 8, the double-sided erasing tool 100 shown in the second embodiment is substantially the same as the double-sided erasing tool 100 shown in the first embodiment, except that the sliding structure 34 includes a thread 341 and a protrusion 342, the rotating member 32 is provided with a first blind hole 322, the protrusion 342 is provided at an end of the first blind hole 322, and the thread 341 forms an outer wall with the guide member 31. Wherein, the end of the rotating member 32 near the guiding member 31 is provided with a protrusion 342, and the guiding member 31 extends into the first blind hole 322. When the rotating member 32 is pressed by the object to be wiped, the rotating member 32 rotates along the thread of the thread 341 through the protrusion 342 and is continuously retracted into the first wiping body 10, thereby achieving the rotation and movement of the rotating member 32.

Third embodiment

Referring to fig. 9, the double-sided erasing tool 100 shown in the third embodiment is substantially the same as the double-sided erasing tool 100 shown in the first embodiment, except that the rotating member 32 is provided with a first blind hole 322, the guide member 31 is provided with a second blind hole 311, the rotating member 32 includes a guide rod 323 disposed in the first blind hole 322, the guide member 31 includes a core rod 312 disposed in the second blind hole 311, a sliding structure 34 is disposed between the core rod 312 and the guide rod 323, and the elastic member 33 is disposed on a surface of the core rod 312.

The sliding structure 34 includes a thread 341 and a convex portion 342, the core rod 312 is provided with a third blind hole 3121, the end portion of the guide rod 323 extends into the third blind hole 3121, the end portion of the guide rod 323 is provided with the convex portion 342, and the inner wall of the third blind hole 3121 is provided with the thread 341. When the rotating member 32 is pressed by the object to be wiped, the guiding rod 323 rotates along the thread 341 through the protrusion 342, and the guiding rod 323 is continuously retracted into the first wiping body 10, so as to rotate and move the rotating member 32.

The rotation piece 32 is integrally formed with the guide bar 323, and the guide piece 31 and the core bar 312 are integrally formed such that the rotation piece 32 moves when the guide bar 323 moves.

Fourth embodiment

Referring to fig. 10, the double-sided eraser 100 shown in the fourth embodiment is substantially the same as the double-sided eraser 100 shown in the third embodiment, except that the sliding structure 34 includes a thread 341 and a protrusion 342, the guide bar 323 has a third blind hole 3231, the end of the core bar 312 extends into the third blind hole 3231, the end of the core bar 312 has the protrusion 342, and the inner wall of the third blind hole 3231 has the thread 341.

When the rotating member 32 is pressed by an external force, the guide rod 323 rotates around the protrusion 342 via the screw 341 and retracts into the first wiping body 10 to rotate and move the rotating member 32.

It is understood that the object erased by the double-sided eraser tool 100 may be glass, but may also be other products, such as acrylic plates, etc.

In summary, the double-sided erasing tool 100 provided in the embodiment of the present application can prevent the hand clamping mechanism 30 from being clamped, and the rotating member 32 can be extended and retracted without setting a switch. And the rotating piece 32 is abutted between the first wiping body 10 and the second wiping body 20, so that the situation that the first wiping body 10 and the second wiping body 20 are completely adsorbed together and are difficult to separate can be avoided. The hand clamping prevention mechanism 30 has the function of a switch, can avoid the situation that a user clamps hands during operation, simplifies the structure of the double-sided erasing tool 100, and improves the experience feeling of the user.

In addition, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present application, and that suitable changes and modifications to the above embodiments are within the scope of the disclosure of the present application as long as they are within the true spirit and scope of the present application.
