The filling plate 6 is connected with the inner wall of the sliding hole 15 in a sliding mode, and the filling plate 6 is used for filling and blocking gaps between the two adjacent groups of fixed cross battens 3 and the two adjacent groups of movable cross battens 5 after sliding out of the inside of the sliding hole 15, so that the probability of recess generated in the process of using the filling plate is reduced. Fixedly connected with spring groove 19 between two adjacent sets of infill panels 6, spring groove 19 are located the inside of sliding hole 15, and spring groove 19's setting is used for utilizing the elastic action of self to promote the infill panel 6 of both sides and moves in opposite directions to stop up the space between two adjacent sets of fixed horizontal bar board 3 and two adjacent sets of horizontal bar board 5. Move horizontal bar board 5 and decide the equal fixedly connected with toper board 10 of opposite side of horizontal bar board 3, the setting of toper board 10 is used for moving horizontal bar board 5 to adjacent two sets of filling board 6 to the inside motion of sliding hole 15 that promotes both sides when deciding between the horizontal bar board 3 to the realization is to the accomodating of filling board 6. The equal fixedly connected with supporting leg 2 in one side four corners of U-shaped back 1, the setting of supporting leg 2 is used for providing the support to U-shaped back 1, makes U-shaped back 1 remain stable. One side of the fixed plate 20 is symmetrically and fixedly connected with a support rod 8, and the support rod 8 is arranged to support the fixed plate 20.

Specifically, referring to fig. 3, sliding grooves 17 are symmetrically formed in the inner wall of the sliding hole 15, a sliding block 16 matched with the sliding grooves 17 is fixedly connected to one side wall of the filling plate 6 close to the sliding hole 15, and the sliding block 16 and the sliding grooves 17 are matched with each other to guide and limit the movement of the filling plate 6.

Specifically, referring to fig. 1, one end of the support rod 8 away from the fixing plate 20 is fixedly connected with a roller 9, and the roller 9 is arranged to roll on the ground during the movement of the fixing plate 20, so as to facilitate the movement adjustment of the fixing plate 20.

Specifically, referring to fig. 1-2, a pull block 11 is fixedly connected to a middle position of a side wall of the fixing plate 20 away from the U-shaped backrest 1, and the pull block 11 is disposed to facilitate movement adjustment of the fixing plate 20.

Specifically, referring to fig. 1, a finger groove 12 is formed in a bottom wall of the pull block 11, and the finger groove 12 is configured to provide an accommodating space for a hand of an operator when the fixing plate 20 is pulled out. The inside symmetry of U-shaped back 1 is equipped with the cushion 13 of looks adaptation, and the setting of cushion 13 is used for covering deciding horizontal slat 3, improves user's comfort level. One side symmetry of cushion 13 is provided with the back pad 14 with moving horizontal bar 5 looks adaptation, and the setting of back pad 14 can be used for acting as the back cushion, can cover moving horizontal bar 5 when moving horizontal bar 5 and being pulled out simultaneously.

Specifically, referring to fig. 3, spring grooves 19 are symmetrically formed in a side wall of the filling plate 6 close to the sliding hole 15, the springs 18 are located inside the spring grooves 19, and the spring grooves 19 are configured to accommodate the springs 18.
