The overall process is that the handle 11 is rotated to drive the first screw 6 to rotate, and the block 7 and the second plate body 8 on the first screw 6 move horizontally on the movable plate 3, so that the two sliding grooves 9 on the second plate body 8 slide with the sliding blocks 10 fixedly connected to the first plate bodies 4, so that the first plate bodies 4 on the upper and lower sides can be relatively rotated with the roller bodies 5, so that the wire mesh can be clamped in the middle, so that the wire mesh can be smoothly guided out, and some guiding function is provided for the wire mesh. When the wire mesh roller 21 unwinds the wire mesh, the wrinkles and bends of the wire mesh caused by too small tension can also be straightened and smoothed.

[0023] In this embodiment, a box body 12 is installed on the two groups of support rods 2, and the two groups of support rods 2 are rotatably connected with a second screw 13. The two groups of second screws 13 penetrate the box body 12, and the two groups of second screws 13 are installed on the first bevel gear 14. A rod body 15 is rotatably connected in the box body 12, and two groups of second bevel gears 16 are rotatably connected on the rod body 15.
