The 222 phase cover merges to hold the seat bow 31 together. The first fixing member 233 is disposed on the upper clip and the through hole 25 between the first shaft. Please refer to the fourth figure, so that the first shaft 232 is rotatably disposed at the front end of the upper clip 221, and The second fixing member 243 is disposed through the through hole 25 between the upper clip and the second shaft column, so that the second shaft post 242 is rotatably disposed at the rear end of the upper clip 221 .

The first and second locking members 231 and 241 may be bolts; and the first and second shaft posts 232 and 242 are provided with corresponding screw holes 26 for respectively supplying the first and second locking members 231, The 241 is screwed and fixed; and the first and second fixing members 233, 243 may be spring pins, screws or fixing posts.

With such a design, the first and second shaft posts 232, 242 and the upper clip 221 are not scattered. Therefore, when assembling, the user does not need to hold the first and second shaft posts 232 and 242 by hand, and the first and second locking members 231 and 241 are sequentially passed through the through holes 212 of the seat body, respectively. The groove 223 of the upper clip is screwed with the first and second shaft posts 232, 242 to achieve the purpose of locking the seat cushion 3. When the angle of the seat cushion 3 needs to be adjusted (as shown in the fifth figure), the angle of the seat cushion 3 can be adjusted by simply loosening the first and second locking members 231, 241, and only the coupling block 22 needs to be rotated by an angle. The angle of the bicycle seat cushion 3 can be adjusted quickly and accurately. Not only allows the user to conveniently and quickly install and adjust the angular position of the seat cushion 3, but also relieves the user from worrying about the loss of the first and second shaft posts.
