Preferably, the cross-section of the sliding groove is T-shaped and is in an elongated shape, and the T-shaped design restrains the wiper blade so that the wiper blade is difficult to separate from the wiper blade holder.

Preferably, the sliding structure comprises a pair of clamping grooves formed in the inner bottom wall of the T-shaped sliding groove from outside to inside, the clamping grooves and the sliding groove extend along the length direction of the wiper blade frame, a plurality of rolling balls are arranged in the clamping grooves, and the contact area between the wiper blade and the sliding groove is reduced due to the design of the balls, so that the wiper blade is facilitated to move.

Preferably, the cross section of the clamping groove is circular with a major arc, and most of the balls are bound by the shape, so that the balls roll in the clamping groove.

Preferably, the two ends of the wiper blade frame are provided with slots, the end cover comprises a cover body embracing the end part of the wiper blade frame, and the cover body is integrally formed with an insertion block penetrating into the slots.

Preferably, the sliding sheet is made of hard materials and is bonded in the groove formed in the bottom surface of the inserting part, the hard materials are not easy to deform, and the contact area between the sliding sheet and the ball is ensured.

Compared with the related art, the windscreen wiper for the special vehicle has the following beneficial effects:

the wiper blade frame is internally provided with the sliding groove, the wiper blade is matched with the sliding groove, and the sliding structure is arranged in the sliding groove and matched with the sliding sheet of the wiper blade, so that the wiper blade and the wiper blade frame are assembled more smoothly, the operation is simple and convenient, and the maintenance cost is reduced.

The design of ball has reduced wiper blade and spout area of contact to replace original plane friction with rolling friction, reduced the frictional force when assembling, be favorable to more changing.
