[0002] A window scraper is also commonly known as a window cleaner or a window wiper. It is a tool specifically used to clean windows and window glass surfaces. It is generally composed of a scraper head, a handle, and a connecting rod. The design of the window scraper allows users to easily scrape off water stains, stains, or other impurities on the window, making the window surface clean and bright. The cleaning head of an existing window scraper is usually fixed and cannot be adjusted. When wiping the glass, some blind corners are difficult to clean, affecting the overall cleanliness.

[0003] After searching, it was found that the patent with publication number CN203341648U disclosed an angle-adjustable window scraper, which adopts an elastic reset part to connect the rod body and the window scraper head, and the angle of the window scraper head can be freely adjusted within a large range; the elastic reset part has its own elasticity and restoring force. After the angle of the window scraper head is adjusted, the elastic reset part will try to restore it to its original position, which will cause the window scraper head to be unable to stably maintain the adjusted angle, and the angle is different each time, and it is impossible to achieve precise control of the angle of the window scraper head as needed. In view of this, an angle-adjustable window scraper is designed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an angle-adjustable window scraper, which solves the problem that the elastic return member has its own elasticity and restoring force. After the angle of the window scraper head is adjusted, the elastic return member will try to restore it to its original position, which will cause the window scraper head to be unable to stably maintain the adjusted angle, and the angle is different each time, making it impossible to achieve precise control of the angle of the window scraper head as needed.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an angle-adjustable window scraper, comprising a secondary rod, a strip groove is provided on the outer surface of the secondary rod, a swing rod is rotatably connected to the secondary rod, and a pull rope is fixedly connected to one end of the swing rod;

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the window scraper head 9 is detachably connected with a wiping cloth 13, which is adhered to the bottom of the window scraper head 9 by Velcro. The wiping cloth 13 can absorb dust, stains and moisture on the surface of the window and glass. The wiping cloth 13 is made of a soft and highly absorbent material, which can fit tightly to the surface of the window or glass and effectively remove stains.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a scraper strip 12 is fixedly connected to the window scraper head 9, and the cross section of the scraper strip 12 is triangular. The scraper strip 12 can further clean the window and glass surface and scrape off the residual moisture and stains. Its design is usually relatively hard and can fit closely to the window surface to ensure the scraping effect. The scraper strip 12 can completely scrape off the stains and moisture that the wiping cloth 13 cannot completely remove, so that the window surface is restored to brightness.

[0029] like Figure 2 and Figure 3 As shown, the center of the arc groove on the arc block 6 and the rotation point of the auxiliary rod 1 and the swing rod 3 are located at the same position. When the pull rope 4 is pulled, the swing rod 3 can rotate in the strip groove 2 of the auxiliary rod 1, and the fixed block 5 can slide on the arc block 6 to avoid interfering with the swing of the swing rod 3.

The pull ring 17 facilitates pulling the pull rope 4.

[0032] Working principle: Pull the pull rope 4 downward through the pull ring 17, pull the swing rod 3 through the pull rope 4, the thrust spring 11 is forced to shrink, the swing rod 3 rotates in the strip groove 2 of the auxiliary rod 1, and the fixed block 5 slides on the arc block 6, driving the window scraper head 9 to swing upward through the fixed rod 8;

[0033] When the pull rope 4 is loosened, the rebound force of the thrust spring 11 pushes the swing rod 3, allowing the swing rod 3 to rotate in the strip groove 2 of the auxiliary rod 1, and driving the window scraper head 9 to swing downward through the fixed rod 8. The angle of the window scraper head 9 can be adjusted as needed. The user can adjust the angle of the window scraper head 9 more accurately by the pulling force of the pull rope 4, so that the window scraper head 9 can better fit the shape and inclination of the window surface, without repeated attempts and adjustments of the angle, which helps to reduce dead angles and omissions during window cleaning and improve cleaning efficiency.
