A circle of locking grooves is provided on the side opposite to the convex ridges, and the fixed shaft can selectively make the convex ridges on its outer periphery engage or not engage with the locking grooves on the support plate through axial movement, thereby realizing circumferential fixation or non-fixation of the fixed shaft and the support plate; the principle of this design is to control the rotation by the fixed shaft, specifically, the circumferential fixation of the fixed shaft and the support plate is adjustable, when the convex ridges on the outer periphery of the fixed shaft engage with the locking grooves on the support plate, the angle is locked, and when the convex ridges on the outer periphery of the fixed shaft do not engage with the locking grooves on the support plate, the angle can be rotated to adjust the angle.

[0007] Furthermore, the fixed shaft is provided with an integrally arranged first end cover at the end portion on one side of the first support sleeve, and the function of the first end cover is to cover the internal structure and improve the appearance.

[0008] Furthermore, the fixed shaft is provided with a second end cover at the end on one side of the second supporting sleeve, and the second end cover is provided with two elastic locking buckles. The interior of the fixed shaft is hollow and a locking buckle hole cooperating with the elastic locking buckle is provided on the fixed shaft. The second end cover is inserted into the fixed shaft by means of the elastic locking buckle and hooked on the locking buckle hole to be fixed to the fixed shaft; the function of the second end cover is to fix the fixed shaft so that it will not separate from the first supporting sleeve, the second supporting sleeve and the supporting plate.

[0009] Furthermore, a spring is provided between the second end cover and the second support sleeve. The function of the spring is to facilitate the angle adjustment of the brush rod. Specifically, under normal conditions, the fixed shaft is biased toward one side of the second support sleeve, and the convex ridges on the outer periphery of the fixed shaft engage with the locking slots on the support plate, and the angles of the two sections of the brush rod are fixed. When adjusting the angle, the second end cover is pressed, the spring is compressed, and the second end cover also drives the fixed shaft to move in the direction of the first support sleeve, thereby making the convex ridges on the outer periphery of the fixed shaft not engage with the locking slots on the support plate. After adjustment, the fixed shaft is restored under the action of the spring reset, and the angle is fixed. The advantage of this design is that it is very convenient to adjust and fix, and you only need to press the second end cover.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the first bending mechanism and the second bending structure are arranged so that the wiping piece can rotate around axes in two different directions, with a high degree of freedom, which makes it more convenient to wipe the exterior window.
