The outer end of the threaded rod 4 is connected with the middle of the inner end of the screw plate 5. The slider 6 is slidably connected to the inner side of the slide 3. A threaded sleeve 7 is arranged in the interior of the slider 6. The inner wall of the threaded sleeve 7 is screwed to the outer wall of the threaded rod 4. The top of the support beam 8 is connected to the bottom of the hinge block 9, and the middle part of the outer side of the hinge block 9 is movably connected to the inner side of the hinge frame 11 through the hinge shaft 10, and the top of the hinge frame 11 is connected with a movable clamping mechanism; by turning the screw plate 5, the corresponding threaded rod 4 can be rotated, and the threaded rod 4 can be screwed with the threaded sleeve 7 to make the slider 6 move laterally on the inner side of the slide 3. After it is in place, it is constrained by the hinge frame 11 through the hinge shaft 10 to move on the outer side of the hinge block 9, so that the movable clamping mechanism acts on the temporary fixation of the shielding door beam, and then the straightening mechanism 2 acts on the bending part of the beam to support it, and it is constrained by the hinge shaft 10 on the outer side of the hinge block 9 through the hinge frame 11, and the movable clamping mechanism constrains the straightening.

[0025] The movable clamping mechanism includes a restraining frame 12, a clamping screw sleeve 13, a clamping screw 14, a clamping wrench 15, a movable shaft frame 16, a rotating shaft 17 and a rotating roller 18. The top of the articulated frame 11 is connected to the middle of the bottom end of the restraining frame 12, the inner side of the middle of the top end of the restraining frame 12 is connected to the outer side of the clamping screw sleeve 13, the inner wall of the clamping screw sleeve 13 is screwed to the outer wall of the clamping screw 14, the top of the clamping screw 14 is connected to the middle of the bottom end of the clamping wrench 15, and the bottom of the clamping screw 14 is rotatably connected to the middle of the top end of the movable shaft frame 16.
