The bottom of the fixing device is fixedly connected with support legs. The outer wall of the support legs is rotatably connected with a housing. One side of the housing close to the support legs is fixedly connected with a threaded rod. The threaded rod is threadedly connected with a threaded slider. The bottom of the threaded slider is fixedly connected with a gear device. The gear device is engaged with a rack. The rack is fixedly connected to the upper surface of the pressing device. The bottom of the pressing device is fixedly connected with a machine housing. The inner wall of the machine housing is rotatably connected with a roller device.

The reduction wheel will slide in the reduction chute to generate resistance, achieving the effect of shock absorption protection, and it has strong practicability.

[0016] 2. Through the auxiliary buffer device of the utility model, when the fixed plate contracts and rises, it can push the elastic resistance rod. When the elastic resistance rod is compressed, it will generate resistance. At the same time, the friction block will rub against the side of the fixed plate to generate resistance again, strengthening the buffering effect on the main body of the stair plate bending device and further enhancing the practicability of the whole device.
