By using the gear rack meshing, when the second round block 419 moves along the straight groove 47 toward the pier column, the power round block 421 drives the sponge plate 49 to move in the opposite direction of the overall movement direction of the auxiliary component 4, which is convenient for smoothing the film and making the film close to the pier column. When the second round block 419 moves along the straight groove 47 away from the pier column, the power round block 421 drives the sponge plate 49 to move in the same direction as the overall movement direction of the auxiliary component 4, but the speed is faster than the auxiliary component 4, so as to tighten the film.

[0064] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
