The working process of the invention is as follows:

the invention relates to a magnetic attraction part power anti-drop window cleaner base which comprises a base body, a cover plate, a magnetic attraction part, a window cleaner base body, under the action of the magnetic force on the two bases, the bases are attached to the surface of the glass, so that the glass can be normally wiped, the magnet 122 on the opposite base attracts the magnetic part 12, so that the suction cup 152 and the glass are kept in a non-attraction state, the suction cup 152 is prevented from being attracted on the glass, the moving resistance is increased, and after the base is separated from the magnetic attraction of the base opposite to the glass, the magnetic attraction to the magnetic part 12 disappears, at this time, under the elastic force of the magnetic part 12, the end of the rocker arm 151 is pressed to turn over the rocker arm 151, so that the suction cup 152 at the other end of the rocker arm 151 is attached to the glass, the base can be fixed by the suction force of the suction cup 152, although the existing window cleaners are all provided with safety ropes, the window cleaner has free falling body movement with one end at a distance, and the base is prevented from falling freely to break glass downstairs or break the window cleaner. The working mode of the limiting mechanism 13 is as follows: when the position-limiting mechanism 13 shown in fig. 4 is operated, the rotating rod 131 is manually rotated, so that the hook 132 at the lower end of the rotating rod 131 is far away from the magnetic part 12, and the magnetic part 12 can freely move up and down; when the position-limiting mechanism 13 shown in fig. 5 is operated, the hook 132 at the lower end of the sliding seat 133 is away from the magnetic-attracting portion 12 by manually sliding the sliding seat 133, so that the magnetic-attracting portion 12 can move up and down freely; when the limiting mechanism 13 shown in fig. 6 is operated, the turning rod 134 is turned manually, so that the turning rod 134 rotates around the hinge shaft, and the hook 132 at the lower end of the turning rod 134 is far away from the magnetic attraction part 12, so that the magnetic attraction part 12 can move up and down freely; the sliding plate is inserted into or pulled out of the slot by moving the sliding plate on the sliding guide rail, and when the sliding plate is inserted into the slot, the guide rod 161 cannot slide up and down, so that the purpose of limiting the magnetic attraction part 12 is achieved.

According to the base of the magnetic part power anti-drop window wiper, the magnetic part 12, the rocker arm 151, the sucker 152 and the elastic part are matched, so that the sucker 152 is far away from glass to be wiped in a wiping state, and can be close to and adsorbed on the glass only when falling off accidentally, the resistance of the window wiper in the window wiping process cannot be increased, and meanwhile, the sucker 152 cannot leave scratches on the glass, so that the base is simple in structure and reliable in performance, and the window wiper can be well prevented from falling off;

one end of the magnetic suction part 12 is hinged to the main seat body 11, so that the magnetic suction part 12 can be quickly far away from the lower surface of the main seat body 11 and can be effectively limited, meanwhile, the limiting adjustment operation is simple and convenient, and the phenomenon that the hands of two main seat bodies 11 are injured by clamping under the action of magnetic suction force can be better prevented;

through adjusting magnetism guide part 16 elasticity setting on main seat body 11 through buffering with magnetism portion 12 of inhaling, can make the in-process of placing on glass of window cleaner, avoid the hard collision problem that strong magnetic force leads to, can effectively reduce the noise and bump broken glass's risk, main seat body 11 can keep away from glass by elasticity simultaneously, stretch into the clearance between main seat body 11 and the glass through the hand and can be convenient take off and wipe the body, adjust limit nut 162 position on guide bar 161 through rotating simultaneously, change buffer spring 163's elasticity, reach the purpose that changes the depth of fall of magnetism portion 12 under the effect of equal magnetic attraction, and then reach the effect of adjusting operating condition magnetic attraction size, the adaptation is cleaned the glass of different thickness.

The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
