[0027] Please refer to Figure 2-3 , the angle adjustment mechanism includes a rotating block 31 rotatably connected to one side of the fixing plate 1. A U-shaped connecting block 32 is welded to the outside of the rotating block 31. A second placement groove 33 is formed on one side of the U-shaped connecting block 32, and the second steel bar 23 is located inside the second placement groove 33. A first hollow block 34 is welded to one side of the fixing plate 1. Inside the first hollow block 34, there is a worm 35 rotatably connected. A worm gear 36 is welded to the outside of the rotating block 31, and the worm gear 36 meshes with the worm 35. A fixed disk 37 is welded to one side of the worm 35, and a fixed block 38 is welded to one side of the fixed disk 37.

[0028] The rotating block 31 can rotate on one side of the fixing plate 1 and drive the U-shaped connecting block 32 to rotate together. The second placement groove 33 formed on one side of the U-shaped connecting block 32 can place and position the second steel bar 23, so that the second steel bar 23 can be stable on one side of the first steel bar 22 and can drive the second steel bar 23 to rotate together when the rotating block 31 rotates, realizing the angle adjustment of the second steel bar 23. At this time, the second steel bar 23 can be welded to the first steel bar 22 at different angles, and the contact points of the rotating block 31 with the first steel bar 22 and the second steel bar 23 are on the same line. Even if the rotating block 31 rotates, the second steel bar 23 can still keep in contact with the first steel bar 22, so that welding can be carried out smoothly;

[0029] The first hollow block 34 can support the worm 35, and the worm 35 can drive the worm gear 36 to rotate. The worm gear 36 is connected to the rotating block 31 and can further drive the rotating block 31 to rotate together.

The fixed block 38 can drive the fixed disk 37 to rotate by rotation and further drive the worm 35 to rotate together, making the rotation of the worm 35 more labor-saving and convenient.

[0030] Please refer to Figure 2, on one side of the fixed plate 1, an L-shaped connecting block 41 is welded. On the outer side of the rotating block 31, a scale plate 42 is provided, and the scale plate 42 is welded to the L-shaped connecting block 41. On one side of the scale plate 42, a pointer 43 is provided, and the pointer 43 is welded to the rotating block 31. The L-shaped connecting block 41 and the scale plate 42 are located on the outer side of the rotating block 31, and the pointer 43 is connected to the rotating block 31, so that when the rotating block 31 rotates, it can drive the pointer 43 to move on one side of the scale plate 42, thus accurately adjusting the rotation welding angle of the second steel bar 23.

[0031] Please refer to Figure 5 , on the upper side of the U-shaped connecting block 32, a threaded groove 51 is opened, and the threaded groove 51 communicates with the second placement groove 33. Inside the threaded groove 51 of the U-shaped connecting block 32, a threaded rod 52 is threadedly connected. The threaded rod 52 can move inside the threaded groove 51 by rotation and, after moving, squeeze and fix the second steel bar 23, which can not only make the second steel bar 23 more stable but also fix the second steel bars 23 with different diameters.

[0032] Please refer to Figure 4 , on one side of the fixed plate 1, a limiting groove 61 is opened. Inside the limiting groove 61 of the fixed plate 1, a limiting block 62 is rotatably connected, and the limiting block 62 is an integrally cast part with the rotating block 31.

[0033] Please refer to Figure 2 , on one side of the first hollow block 34, a first fixing ring block 71 is provided. On the side of the first hollow block 34 away from the first fixing ring block 71, a second fixing ring block 72 is provided, and both the first fixing ring block 71 and the second fixing ring block 72 are integrally cast parts with the worm 35.

[0034] Please refer to Figure 1 , on the upper side of the fixed plate 1, a pressing plate 81 is movably hinged through a hinge. On the lower side of the pressing plate 81, a rubber pad 82 is attached. The pressing plate 81 can be rotated and pressed on the upper side of the fixed plate 1, and the rubber pad 82 can move into the first placement groove 21 and fix the first steel bar 22 through its large friction force, making it not easy for the first steel bar 22 to move.

[0035] Please refer to Figure 1A second hollow block 91 is welded to one side of the fixed plate 1, a handle 92 is provided on one side of the second hollow block 91, and the handle 92 is welded to the fixed plate 1.

[0036] The working principle and use process of the utility model are as follows: when using the device, firstly, the first steel bar 22 is placed inside the first placement groove 21, and then the second steel bar 23 is placed inside the second placement groove 33, and the threaded rod 52 is rotated to move inside the threaded groove 51 to position the second steel bar 23, and then the fixing block 38 is rotated to drive the fixing plate 37 to rotate, and the fixing plate 37 will drive the worm gear 36 to rotate through the worm 35, and at the same time, the worm gear 36 will drive the rotating block 31 to rotate together, and then the rotating block 31 will drive the second steel bar 23 to rotate through the U-shaped connecting block 32 to achieve the angle adjustment of the second steel bar 23. The second steel bar 23 can be welded with the first steel bar 22 at different angles, and the contact points of the rotating block 31 with the first steel bar 22 and the second steel bar 23 are on the same line. Even if the rotating block 31 rotates, the second steel bar 23 can maintain contact with the first steel bar 22, so that welding can be carried out smoothly. The meshing of the worm 35 and the worm wheel 36 has a certain self-locking property, so that the rotating block 31 is not easy to continue to rotate after rotation, thereby making the second steel bar 23 more stable. This can solve the problem that the contact point of the two steel bars is not on the same line with the steel bar tube, and one of the steel bars cannot continue to contact with the other steel bar for welding after rotation.

[0037] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
