Window wiper capable of multi-point positioning and reciprocated rotating

Abstract

The invention provides a window wiper capable of multi-point positioning and reciprocated rotating. A wiping head operating in a multi-point positioning and reciprocated rotating modes is located at the front end of an arm support, a seat body connected with the rear end of the arm support is fixed on a window frame, the seat body and the wiping head are driven by virtue of a rope, the driving and driven wheels of a rope wheel set are respectively arranged in the seat body and a wiping head shell, a locating shaft pin fixed in a wheel shell of the wiping head props against and presses downward glass and plays a role in locating, a wiping brush rotates around the locating shaft pin, and automatically adapt to the shape of the window frame to change the working track, the driving and driven wheels of the rope wheel set are respectively manufactured into a conical stroke part and a conical back track part, the stroke wheel and back track wheel of the driven wheel are integrally molded, and the tops of the two cones are inward (outward), the stroke wheel and back track wheel of the driving wheel are separated, the tops of the two cones are outward (inward), the surface of each cone is processed with spiral line shaped rope grooves, the total lengths of the rope grooves of the driving and driven wheels, stroke wheel and back track wheel are equal, the driving and driven stroke wheels are connected by a stroke rope, the driving and driven back track wheels are connected by a back track rope, the stroke wheel and back track wheel of the driving wheel are meshed with or separated from a guide plate which can slide on a main shaft axially through a clutch tooth, and are driven by the stroke rope or the back track rope, and the driven wheels of the rope wheel set are driven to drive the wiping bush to rotate forward or reversely, thus, after the wiping head is positioned by people standing on the indoor ground, a rocking handle is rotated, thus the glass can be cleaned.
