It should be noted that the first fixing member 210 is fixedly connected to the blade seat 100, and a plurality of first clamping members 300 and a plurality of second clamping members 400 are used, and a first card slot 310 for clamping at least one second clamping member 400 is formed between two adjacent first clamping members 300, and a second clamping member 400 is formed between two adjacent second clamping members 400. A second card slot 320 is provided for at least one first card connector 300 to be connected, so that when the angle of the blade is adjusted, the first card connector 300 is inserted into the corresponding second card slot 320, and the second card connector 400 is inserted into the corresponding first card slot 310, and the second fixing member 220 can be fixed relative to the first fixing member 210 after the angle is adjusted. It should be noted that the second fixing member 220 can be directly connected to the blade body of the blade, that is, when the second fixing member 220 is rotated relative to the first fixing member 210, the angle adjustment of the blade is completed.

[0034] It should be noted that, in this embodiment, the first clamping member 300 is disposed on one side of the first fixing member 210 , and the second clamping member 400 is disposed on a side of the second fixing member 220 facing the first fixing member 210 .
