Two limiting rods 2017 are symmetrically fixedly connected to the outside of L-shaped plate 2 207. Both limiting rods 2017 penetrate L-shaped plate 1 202. When the height position of pressure roller 206 is adjusted, the two limiting rods 2017 are always in the state of penetrating L-shaped plate 1 202 to prevent vertical plate 2 5 from moving. In use, first insert square rod 29 into square frame 20 to place the take-up roller 3. Then push upright plate 25 to drive guide frame 204 to slide along guide post 205. At the same time, roller 203 rolls on top of L-shaped plate 202 to ensure stability when upright plate 25 moves. Then move square frame 7 through support shaft 6 until square frame 7 is fitted on the outside of square rod 8. Then rotate handwheel 2014 to drive screw 2015 to rotate. Through screw sleeve 2016, drive L-shaped plate 207 to slide down along U-shaped rod 2018. At the same time, two limit rods 2017 descend until both limit rods 2017 penetrate L-shaped plate 202 to limit upright plate 25 and prevent it from loosening. Finally, the installation of take-up roller 3 is completed.
