An adjustment mechanism 400 is installed inside the reinforcement back brace mechanism 300. The adjustment mechanism 400 is used to adjust the length of the reinforcement back brace mechanism 300, and the reinforcement back brace mechanism 300 is used to support and reinforce the support beam body 100 and the second support beam body 200.
[0022] In some specific implementation schemes, the reinforcement back brace mechanism 300 includes a connecting rod 310. One end of the connecting rod 310 is fixedly installed with an installation rod 320. The installation rod 320 is hollow. An auxiliary groove is arranged at the inner end of the installation rod 320, and an auxiliary block 331 is slidably connected in the auxiliary groove. The bottom end of the auxiliary block 331 is connected with a moving rod 330. One end of the moving rod 330 is fixedly installed with a connecting plate 340. One end of the connecting rod 310 is fixedly installed with a second connecting plate 360.
[0023] In some specific implementation schemes, both the connecting plate 340 and the second connecting plate 360 are provided with threaded grooves. The connecting plate 340 is fixed to the support beam body 100 through a bolt 350, and the second connecting plate 360 is fixed to the second support beam body 200 through a second bolt 370. The moving rod 330 moves through the adjustment mechanism 400 to adjust the length of the reinforcement back brace mechanism 300, so that the device can support different positions according to the user's usage needs. The connecting plate 340 and the second connecting plate 360 are fixed, and the bolt 350 fixes the connecting plate 340, and the second bolt 370 fixes the second connecting plate 360.
[0024] In some specific implementation schemes, the adjustment mechanism 400 includes a rod body 430. The rod body 430 is rotatably installed inside the installation rod 320. A gear 450 is fixedly sleeved outside the rod body 430. A chute is arranged at the inner end of the installation rod 320, and a mounting block 460 is slidably connected in the chute. A rack 470 is fixedly installed at the bottom end of the mounting block 460. The rack 470 is meshed with the gear 450. One side of the rack 470 is connected to one side of the moving rod 330. The gear 450 rotates through the rod body 430, so that the rack 470 drives the moving rod 330 to move.
[0025] In some specific implementation schemes, a rotating rod 410 is rotatably installed at the inner end of the installation rod 320.

[0029] Working principle: During use, the rotating rod 410 is rotated through the outer holder 411. The rotation of the rotating rod 410 causes the worm 420 to drive the worm wheel 440 to rotate, so that the rod body 430 drives the gear 450 to rotate. The gear 450 rotates through the rod body 430, so that the gear 450 drives the rack 470 to move, so that the rack 470 drives the moving rod 330 to move, so that the length of the reinforcement back rib mechanism 300 is changed, so that the device can support different positions with the connecting plate 340 and the second connecting plate 360 according to the user's needs, and the connecting plate 340 and the second connecting plate 360 are fixed by bolts 350 and second bolts 370, so that the installation of the device is completed. At the same time, when the support effect of the device decreases, the moving rod 330 can be moved to improve the reinforcement effect.
