The support 12 is fixed to the base 13 for the user to exercise his sitting posture. When the user pulls the handle 143 to move towards the direction away from the base 13 in the unlocking state, at this time, the connecting shaft 144 slides to the side of the long hole 125 away from the base 13, and the connecting shaft 144 drives the pin shaft 141 to move towards the direction away from the sliding sleeve, so that the pin shaft 141 is separated from the locking hole 135. At the same time, the spring 142 is compressed such that the spring 142 has elastic potential energy to drive the pin 141 back to the locked position. When the pin 141 is disengaged from the locking hole 135, the locking mechanism 14 loses the limiting action on the support 12, and the support 12 can rotate relative to the sliding sleeve to allow the seat cushion assembly 1 to be stored.

Alternatively, referring to fig. 5, the handle 143 has a circular ring structure. The pull handle 143 includes two semicircular plates symmetrically arranged, which are fastened together to form the pull handle 143. The two semicircular plates are respectively connected and fixed with the two ends of the connecting shaft 144 through screws 145. This configuration facilitates assembly or disassembly of the locking mechanism 14 from the support 12.

The beneficial effects of this embodiment are: by telescopically arranging the seat cushion body 11 at one end of the supporting piece 12, the other end of the supporting piece 12 is rotatably connected with the sliding sleeve, and the sliding sleeve is slidably connected with the guide rail 131. By adjusting the positions of the sliding sleeve and the guide rail 131 and adjusting the telescopic lengths of the seat cushion main body 11 and the supporting piece 12, the position of the seat cushion main body 11 can be adjusted so as to meet the sitting gesture demands of users with different body types. Meanwhile, by utilizing the restriction of the locking mechanism 14 to the support 12, the seat cushion assembly 1 can be unfolded when the user performs sitting riding training, and the support 12 is fixed on the base 13 through the locking mechanism 14; when the user performs standing riding training, the locking mechanism 14 can be operated by the locking mechanism 14 to be separated from the sliding sleeve, so that the support piece 12 can rotate relative to the sliding sleeve and abut against the bracket 2, and the seat cushion assembly 1 can be stored. This structure facilitates the random switching of the seat cushion assembly 1 between the unfolded state and the stored state, facilitates the switching of the sitting riding training and the standing riding training for the user, and does not cause the loss of the seat cushion assembly 1.
