Dual-purpose wiper with replaceable wiper strip

Abstract

The present invention discloses a dual-purpose wiper with a replaceable wiper strip, including a handle, a working head, a wiper strip, a wiper board, or the like. Mainly, the working head is provided with a sliding groove running through in a horizontal direction, and a sliding rib is correspondingly arranged on one side of the wiper strip, so that the wiper strip can be detachably and slidably engaged in the sliding groove through the sliding rib. In addition, the working head is further provided with a lock piece, and the lock piece can lock or unlock the sliding rib for sliding in the sliding groove, so that the wiper strip can be replaced arbitrarily and flexibly, and the wiper strip having an appropriate length can be configured according to an actual use need. In the meantime, detachably insertable lengthening blocks are respectively arranged at two ends of the wiper board for extending a use length, so that the appropriate wiper board can also be selected according to an actual use need, thereby improving versatility of the wiper and reducing the limit on use occasions. In addition, the working head can also form elastic bending relative to the handle for use, and can be swung horizontally at a certain angle relative to the handle for use, making structure design more user-friendly. Therefore, the wiper has use advantages of good hand feeling, easy use, labor saving, good effect, and the like.
