[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.

[0023] See also Figures 1 to 6 A top-button scraper arm composite button connection structure shown in the figure includes a scraper blade assembly and a scraper arm 10. The scraper blade assembly includes a scraper blade 20, a fixing seat 30, and a connecting member 40. The connecting member 40 is connected to the scraper blade 10, and the fixing seat 30 is hinged on the connecting member 40.

[0024] Axial holes 31 a are provided on a pair of side walls 31 of the fixing seat 30 , and axial shafts 41 are provided on a pair of side walls of the connecting member 40 . The axles 41 are hinged in the corresponding axle holes 31 a to form a hinge point A between the fixing seat 30 and the connecting member 40 .

[0025] A composite button is provided at the top 32 of the fixing seat 30; the composite button comprises a button cap 51 and a button cap elastic bracket 52, the button cap elastic bracket 52 comprises a bracket head 52a and an elastic arm 52b, the bracket head 52a is integrally connected with one end of the elastic arm 52b, and the other end of the elastic arm 52b is hinged to the top 32 of the fixing seat 30 through a shaft 52c. The shaft 52c is located between the bracket head 52a and the hinge A of the fixing seat 30 and the connecting member 40.

[0026] The bracket head 52a is embedded in the button cap 51. The bracket head 52a is cross-shaped as a whole, so that the four ribs 52aa of the cross shape can all be in interference contact with the inner surfaces of the four side walls 51a of the button cap 51, ensuring that the button cap 51 is firmly embedded in the bracket head 51.

[0027] A button cap lifting hole 32 a adapted to the button cap 51 is provided on the top 32 of the fixing seat 30 , and the button cap 51 is arranged in the button cap lifting hole 32 a in a manner of being able to be lifted up and down.

[0028] A guide rib 61 is provided on the inner surface of a pair of side walls 31 of the fixing seat 30, and a guide groove 51aa is provided on the two pairs of side walls 51a of the button cap 51. The guide rib 61 is slidably arranged in the guide groove 51aa to guide the lifting and lowering of the button cap 51.

[0029] At least one button hole 11aa is provided on the top 11a of the joint 11 at one end of the scraper arm 10 adjacent to the fixing seat 30, and the button cap elastic bracket 52 drives the button cap 51 to engage in the button hole 11aa.

[0030] A limiting head 33 is provided at one end of the fixing seat 30 away from the composite button, i.e., the button cap 51. The limiting head 33 cooperates with the composite button, i.e., the button cap 51, to limit the position of the scraper arm 10 on the fixing seat 30 in a direction parallel to the length of the scraper blade 20. In addition, a protrusion 34 is provided on a pair of side walls 31 of the fixing seat 30. The protrusion 34 contacts the inner surface of the two side walls 11b of the joint 11 of the scraper arm 10 near one end of the fixing seat 30, so as to limit the position of the scraper arm 10 on the fixing seat 30 in a direction perpendicular to the length of the scraper blade 20.

[0031] In order to press the button cap 51 down when the connector 11 is inserted into the fixing seat 30 , an inclined guide surface 51 ba is provided on one side of the top surface 51 b of the button cap 51 .

[0032] When the scraper arm 10 is pulled backward, the button cap 51 receives the backward pulling force and will drop. During the dropping process, the button cap 51 will be blocked by the guide rib 61 and will not drop excessively. This ensures that the scraper arm 10 and the scraper blade assembly will not be separated, thereby improving reliability.
