The rubber strip 13 is L-shaped, elongated slots are formed in the main wiping body 6 and the auxiliary wiping body 7 corresponding to the rubber strip 13, a U-shaped first plastic piece 17 is arranged in each elongated slot, the bottom of the L-shaped rubber strip 13 is placed on the first plastic piece 17, the top of the L-shaped rubber strip 13 extends out of the elongated slot, a second plastic piece 18 is arranged between the first plastic piece 17 and the L-shaped rubber strip 13, and the L-shaped rubber strip 13 is pressed tightly to complete the fixation of the rubber strip 13.

The first plastic piece 17 is provided with a locking piece abdicating 19, a locking piece 20 is installed in the locking piece abdicating 19, the locking piece 20 is in sliding connection with the main wiping body 6 or the auxiliary wiping body 7, the top of the locking piece 20 is clamped on the second plastic piece 18, the second plastic piece 18 is fixedly locked, and the second plastic piece is prevented from being loosened to cause the adhesive tape 13 to slide off.

The two ends of the universal joint 4, the inner core rod connecting portion 3 and the main wiping body connecting portion 5 are both hollow U-shaped structures, mounting holes 22 are formed in the opposite sides of the universal joint, and the two ends of the universal joint 4, the inner core rod connecting portion 3 and the main wiping body connecting portion 5 are arranged in a staggered mode and are rotatably connected through a cross shaft 21.

All be equipped with a plurality of projections 23 in main body 6 and the vice body 7 of wiping, set up the step hole in the projection 23, put into little ball 24 and ball 14 in the step hole in proper order, and ball 14 surpasss the main body 6 of wiping and vice body 7 of wiping and the side of glass laminating, the top of projection 23 is equipped with spacing collar 25 to ball 14, because the magnetic force that the magnetic force two-sided was wiped is very big relatively, vice body 7 of wiping drops easily otherwise, the main body 6 of wiping and the motion of vice body 7 of wiping are just relatively difficult when magnetic force is great, it will be very smooth and easy to have increased the motion of the two after ball 14, it is more laborsaving light during the use.

And a handle 15 is arranged on the surface of the auxiliary wiping body 7 opposite to the surface jointed with the glass.

The universal joint 4 is externally sleeved with a universal joint outer sleeve 11, the universal joint 4 and the inner core rod connecting part 3 are packaged in the universal joint outer sleeve 11, a fixed side plate 31 is arranged on the inner side face of the end part of the universal joint outer sleeve 11, an articulated shaft 30 is arranged on the fixed side plate 31, the articulated shaft 30 is arranged in a sliding groove 29 in the universal joint outer sleeve 11, and the sliding groove 29 is arc-shaped, so that the main wiping body 6 can rotate at a certain angle relative to the universal joint outer sleeve 11, the included angle between two sections of the universal joint outer sleeve 11 is α, 90 degrees is more than α and less than 180 degrees, when a user is parallel to glass, the user can clean the glass in a most comfortable manner, and the user is prevented from cleaning by adjusting the angle.

The working principle of the invention is as follows: (1) the universal joint 4 is used, so that the universal joint can be directly driven to drive the main wiping body to rotate, and the main wiping body can also be driven to rotate by driving the inner core rod connecting part and the inner core rod, so that no dead angle is generated no matter the double-sided wiping is rotated at any angle, the user experience is improved, the use is convenient, and the labor and the worry are saved;

(6) the included angle between the two sections of the universal joint jacket 11 is α, the included angle is more than 90 degrees and less than α degrees and less than 180 degrees, when a user is used in parallel with the glass, the user can clean the glass in a most comfortable way, and the user is prevented from cleaning by adjusting the angle of the arm;

(7) when the inner core rod 2 drives the main wiping body connecting part 5 to rotate, the driving large gear 8 and the driving small gear 16 synchronously rotate, at the moment, the driven small gear 9 and the driven large gear 10 synchronously rotate to realize the rotation of the main wiping body 6, the gear ratio of the driving large gear 8 to the driving small gear 16 to the gear ratio of the driven large gear 10 to the driven small gear 9 is 2: 1, and when the main wiping body connecting part 5 rotates for half a circle, the main wiping body 6 can be driven to rotate for one circle;

(8) because the magnetic force of the magnetic double-sided eraser is relatively large, otherwise the auxiliary eraser body 7 is easy to fall off, when the magnetic force is large, the main eraser body 6 and the auxiliary eraser body 7 are relatively difficult to move, the ball 14 is added, and then the two can move very smoothly, so that the magnetic double-sided eraser is more labor-saving and portable in use;

(9) the top of the locking block 20 is clamped on the second plastic piece 18 to fix and lock the second plastic piece 18, so that the rubber strip 13 is prevented from slipping off due to loosening, and the rubber strip 13 is more convenient to replace;

(10) through mutually supporting of vertical type muscle 26 and recess 27, realize the sliding connection of outer core bar 1 and inner core bar 2, can realize overall structure's extension or shorten, the tail end of outer core bar 1 sets firmly shaking hands 28, when rotating shaking hands 28, can realize that outer core bar 1 drives the rotation of inner core bar 2, controls more conveniently.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
