5. The back cushion is connected on the crossbeam in a rotating way, so that the relative angle between the back cushion and the crossbeam can be changed according to the needs of a user, the adjusting rod is connected with the back cushion in a rotating way, and the adjusting rod is clamped into the corresponding positioning groove after the angle adjustment of the back cushion and the crossbeam is completed, so that the adjusting rod provides support for the back cushion.

6. In order to facilitate convenient storage after use and reduce the occupation of horizontal space, after use, the bracket is rotated towards the bottom surface of the beam and tightly leans against the bottom surface of the beam, and the backrest is rotated towards the surface of the beam and tightly leans against the surface of the beam, so that a plate is similarly formed and is directly leaned against a corner during recovery.

Compared with the prior art, the supine plate can be adjusted in various use states, meets different use requirements of users, reduces the reduction of storage space after use, and is rich in functions, simple to operate, high in feasibility and convenient to popularize in a large range.

Further, the lower end of the support and the free end of the adjusting frame are fixedly connected with placing rods. The use stability is improved.

Furthermore, a stop lever is fixedly connected to the free end of the adjusting lever, and a limiting barb for preventing the stop lever from sliding out is arranged on the positioning groove. Effectively preventing the adjusting rod from sliding out of the positioning groove in the using process.

Further, the rotating end of the adjusting bracket is in an arc shape which is convenient to rotate. The rotating efficiency of the adjusting bracket is improved.

Furthermore, foam is arranged on the foot hooking frame and the leg support. The use comfort is improved.

Furthermore, the placing rod fixedly connected to the support is rotatably connected with a plurality of moving wheels. Is convenient to use and recycle.
