[0018] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementations.
[0019] See also Figures 1 to 7 A rear-scraping flexible scraper arm and scraper blade connection structure shown in the figure includes a scraper blade 10, a fixing seat 20, a connecting piece 30, a scraper arm 40 and a buckle. The scraper blade 10 is fixed on the fixing seat 20, and the connecting piece 30 is hinged on the fixing seat 20.
[0020] The utility model is characterized in that a slot 60 is provided between the top surface of the fixing seat 20 and the top surface of the connecting member 30, and the scraper arm 40 is inserted into the slot 60; and a hole 41 is provided at the end of the scraper arm 40 inserted into the slot 60.
[0021] A U-shaped notch 31 is provided on the connecting member 30 to expose the fixing seat 20 and the hole 41 .
[0022] The buckle is a U-shaped buckle 50, and a protrusion 51a is provided on the inner top surface of the cross arm 51 of the U-shaped buckle 50. After the U-shaped buckle 50 is inserted into the U-shaped notch 31, the protrusion 51a is inserted into the hole 41, so that the scraper arm 40 is connected with the connecting piece 30 and the fixing seat 20.
[0023] In addition, a limiting groove 21 is respectively provided at the position of the U-shaped notch 31 of the connecting member 30 on the two side walls of the fixing seat 20, and an inclined wedge surface 22 (the aforementioned first inclined wedge surface) is provided in each limiting groove 21. A boss 52a is respectively provided at the end of the two vertical arms 52 of the U-shaped buckle 50, and an inclined wedge surface 52b (the aforementioned second inclined wedge surface) is provided on each boss 52a. After the U-shaped buckle 50 is inserted into the U-shaped notch 31, the boss 52a is inserted into the corresponding limiting groove 21, and the inclined wedge surface 22 and the inclined wedge surface 52b are wedged with each other, so that when the U-shaped buckle 50 is pulled out upward with a certain force, the two vertical arms 52 of the U-shaped buckle 50 can be bounced open and move upward. When the U-shaped buckle 50 moves upward a certain distance, the upper surface of the boss 52a will hit the upper surface of the limiting groove 21, preventing the U-shaped buckle 50 from continuing to move upward and not detaching from the fixing seat 20.
