Since the internal threaded tube 303 is threadedly connected to the threaded rod 306, the threaded rod 306 will rise and fall with the rotation of the internal threaded tube 303. The lifting and lowering of the threaded rod 306 drives the first trapezoidal block 307 to move. The first trapezoidal block 307 drives the first mounting rod 310, the fixing block 315 and the rectangular insertion strip 316 to move by squeezing the second trapezoidal block 309. When the rectangular insertion strip 316 is inserted into or pulled out of the socket 320 on the cross bar 2, the position of the backrest assembly 3 can be fixed or released. At the same time, the first The mounting rod 310 drives the fixing block 315 to contact or move away from the engaging teeth on the inner side of the second shell 317 through the engaging teeth, thereby realizing the angle limitation and adjustment of the backrest assembly 3. Pulling the movable block 404 drives the second mounting rod 405 and the plug plate 408 to move. After the plug plate 408 is pulled out of the slot 409, the table board assembly 4 can be rotated around the cross bar 2 to achieve angle adjustment. When the table board assembly 4 needs to be fixed, just insert the plug plate 408 into the corresponding slot 409.
