A threaded cylinder 13 is detachably installed on the upper end of the fixing frame 7. A limiting groove 11 is opened in the middle of the upper end of the fixing frame 7. The limiting groove 11 is equilateral hexagonal. A strip groove 12 is opened on one side of the upper end of the fixing frame 7. The strip groove 12 and the limiting groove 11 are connected. A nut 14 and a limiting plate 15 are fixedly installed on the lower outer wall of the threaded cylinder 13. The nut 14 is inserted into the limiting groove 11, and the limiting plate 15 is... Located at the upper end of the fixed frame 7, the threaded cylinder 13 is limited. At the same time, the front and rear sides of the upper end of the fixed frame 7 are fixed with pressure plates 16 by bolts. The pressure plates 16 are located on the upper side of the front and rear ends of the fixed frame 7, fixing the limiting plate 15 and thus fixing the threaded cylinder 13.

An anti-slip pad 20 is fixedly installed on the outer end of the circular plate 19. The anti-slip pad 20 can contact the outer wall of the movable plate 8. More specifically, after the pressure roller 9 is moved to a suitable position by the threaded rod 17, the threaded rod 18 is rotated to drive the circular plate 19 and the anti-slip pad 20 to move, and to make the anti-slip pad 20 and the side wall of the movable plate 8 in close contact, thereby further fixing the pressure roller 9.

[0029] like Figure 4 As shown, in some embodiments, a plurality of guide rollers 28 are uniformly fixedly installed on the inner ends of the fixed plate 26 and the guide plate 27. The rotating rollers of the guide rollers 28 are in contact with the side wall of the plastic plate to facilitate the sliding of the plastic plate.
