[0022] In the above structure, by installing storage box 2 and connecting box 3 on both sides of the outer wall of wheelchair seat 1, and arranging safety fixing belt 11 in the inner cavity of storage box 2, when the user uses the wheelchair, storage box 2 and connecting box 3 can be installed on both sides of the outer wall of the wheelchair, then safety fixing belt 11 is pulled, and the outer wall of connecting head 12 is inserted into the inner cavity of connecting box 3, so that safety fixing belt 11 can play a certain binding role on the user.

[0023] In a preferred embodiment, the outer wall of the connecting box 3 is sized to match the outer wall of the wheelchair seat 1, and the storage box 2 and the connecting box 3 are both made of engineering plastic.

[0024] In the above structure, when the storage box 2 and the connecting box 3 need to be installed, the outer wall of the connecting box 3 and the storage box 2 are clamped on the outer wall of the wheelchair seat 1, and then the fixing bolt 5 is rotated to make the outer wall of the fixing bolt 5 contact the outer wall of the wheelchair seat 1, thereby achieving the installation of the storage box 2 and the connecting box 3.

[0025] In a preferred embodiment, the outer wall of the connecting box 3 is sized to match the outer wall of the wheelchair seat 1, and the storage box 2 and the connecting box 3 are both made of engineering plastic.

[0026] In the above structure, the winding spring 9 is arranged on the top of the bearing plate 7, and the winding spring 9 is connected to the rotating shaft 8 and the bearing plate 7. When the safety fixing belt 11 is pulled, the rotating shaft 8 rotates, thereby driving the winding spring 9 to deform. After the safety fixing belt 11 and the connecting head 12 are released from the inner cavity of the connecting box 3, the rotating shaft 8 is driven to rotate under the action of the winding spring 9, so that the safety fixing belt 11 is wound on the outer wall of the rotating shaft 8.
