At present, in order to ensure the neatly arranged welding effect, the reinforcement rods are limited by position constraints during welding. However, in specific applications, it is found that the ends of the reinforcement rods are uneven, so the reinforcement rods need to be trimmed. Utility Model Content

[0014] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0015] Figure 1 A three-dimensional structural diagram of one embodiment is shown.
[0016] Figure 2 An enlarged view of A is shown. DETAILED DESCRIPTION
[0017] like Figure 1~Figure 2As shown, a welding bracket includes a rectangular frame 1, on which a plurality of waist-shaped rings 11 are installed, and a plurality of limiting grooves 12 are provided on the waist-shaped rings 11, and the limiting grooves 12 are U-shaped structures. A pair of end columns 10 are respectively provided at both ends of the rectangular frame 1, and a spring pin 2 is provided at the outer end of the end column 10, and a movable plate 21 is sleeved on the spring pin 2, and a spring 20 is provided on the inner side of the movable plate 21, and the spring 20 is sleeved on the spring pin 2, and a movable support plate 22 is provided at the upper end of the movable plate 21, and an L-shaped plate 23 is provided at the inner end of the movable support plate 22, and a plurality of limiting sleeves 25 are provided on the inner wall of the L-shaped plate 23. In addition, a moving hole is provided on the end column 10, and a movable rod 24 is movably provided in the moving hole, and the upper end of the movable rod 24 is arranged at the inner end of the movable support plate 22.
[0018] A pair of rotating convex plates 3 are respectively installed at both ends of the rectangular frame 1. A rotating plate 31 is rotatably provided at the outer end of the rotating convex plate 3. The inner end of the rotating plate 31 is an arc-shaped structure. The inner end of the rotating plate 31 acts on the outer wall of the L-shaped plate 23. A connecting rod 32 is provided at the outer end of the rotating plate 31. An inner extending movable plate 33 is sleeved on the connecting rod 32. A waist-shaped hole 34 is opened on the inner extending movable plate 33. The connecting rod 32 passes through the waist-shaped hole 34. A pulling side plate 35 is installed at the outer end of the inner extending movable plate 33. A pulling end plate 36 is provided at one end of the pulling side plate 35. A guide through rod 37 is passed through the pulling end plate 36. The inner end of the guide through rod 37 is arranged at one side of the rectangular frame 1. A screw rod 38 is rotatably provided at one side of the rectangular frame 1. A rotating cap 39 is provided at the outer end of the screw rod 38. The screw rod 38 is screwed to the pulling end plate 36.
[0019] When operating this embodiment, the operator first places the condenser tube on the waist-shaped ring 11.
[0020] Then the operator places the reinforcing rods in the limiting grooves 12 one by one.
[0021] The operator can then push the L-shaped plate 23 inward so that the inner wall of the L-shaped plate 23 is pressed tightly against the end plate of the reinforcing rod, and limit the end of the reinforcing rod through the limit sleeve 25, and then perform the welding operation. After the welding is completed, the action on the L-shaped plate 23 is cancelled, and then the condenser is taken out.
[0022] In addition, as another embodiment, the operator rotates the screw rod 38 by rotating the cap 39. The rotation of the screw rod 38 will cause the pulling end plate 36 to move inward. The inward movement of the pulling end plate 36 will act on the connecting rod 32 through the waist-shaped hole 34, thereby causing the rotating plate 31 to rotate. When the rotating plate 31 rotates, its inner end will act on the L-shaped plate 23, and then the two ends of the reinforcing rod will be limited and constrained through the L-shaped plate 23. After the limiting is completed, the reinforcing rod is welded. After the welding is completed, the force on the L-shaped plate 23 is cancelled, so that the L-shaped plate 23 moves outward under the action of the spring 20, and then the condenser is taken out.

Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
