Two second synchronous pulleys 14 are rotatably connected inside the second movable groove 13, and one end of the two second synchronous pulleys 14 passes through the inner wall of the second movable groove 13 and extends into the multiple first movable grooves 10 respectively, and is fixed to two of the first synchronous pulleys 11 respectively. A second synchronous belt 15 meshes between the two second synchronous pulleys 14.
[0055] Gear groove 16 is formed inside the protective device 1 and is connected to the second movable groove 13. A first bevel gear 17 and a second bevel gear 18 are rotatably connected inside the gear groove 16 and mesh with each other. One end of the first bevel gear 17 passes through the inner wall of the gear groove 16 and extends into the second movable groove 13 and is fixed to one of the second synchronous pulleys 14.

[0056] A fixing component is located on the protective device 1 and is used to fix the rotating rod 19.
[0057] In operation, the user manually rotates the lever 19, causing the lever 19 to rotate the second bevel gear 18 within the gear groove 16. The second bevel gear 18 then rotates the first bevel gear 17 within the gear groove 16, causing the first bevel gear 17 to rotate one of the second synchronous pulleys 14 within the second movable groove 13. This second synchronous pulley 14, via the second synchronous belt 15, drives the other second synchronous pulley 14 to rotate.

[0063] In use, the user manually rotates the threaded rod 25, causing the second fixing block 24 to be acted upon by the threads of the threaded rod 25. This causes the second pressing block 23 to move along the third sliding groove 22, moving it towards the rotating rod 19. When the second pressing block 23 reaches a position where it cannot move further, the second pressing block 23 and the first pressing block 20 will fix the rotating rod 19 to the protective device 1, preventing it from rotating and ensuring that the rotating rod 19 will not be affected by external factors.

[0072] In use, the user manually places the two steel structures to be welded within the two limiting frames 2, with the ends of the two steel structures to be welded touching. Then, the user manually rotates the rotating rod 19, causing the rotating rod 19 to drive the second bevel gear 18 to rotate within the gear groove 16. The second bevel gear 18 then drives the first bevel gear 17 to rotate within the gear groove 16, causing the first bevel gear 17 to drive one of the second synchronous pulleys 14 to rotate within the second movable groove 13. This causes one of the second synchronous pulleys 14 to drive the other second synchronous pulley 14 via the second synchronous belt 15.

When the two extrusion plates 4 move to a position where they cannot move, they will fix two steel structures in two limiting frames 2, ensuring that the user can quickly fix the steel structures in the limiting frames 2 and prevent them from moving. Then, the user can manually rotate the threaded rod 25, causing the second fixing block 24 to be acted upon by the thread of the threaded rod 25, driving the second extrusion block 23 to move along the third sliding groove 22, causing the second extrusion block 23 to move towards the rotating rod 19. When the second extrusion block 23 moves to a position where it cannot move, the second extrusion block 23 and the first extrusion block 20 will fix the rotating rod 19 to the protective device 1 and prevent it from rotating, ensuring that the rotating rod 19 will not be affected by external factors.
