[0030] When the bucket 1 needs to be repaired by welding, the support tube 2 is first placed inside the bucket 1, and then the threaded rod 3 is rotated to drive the connecting ring 4 to move downward, and the connecting ring 4 and the connecting rod 5 are moved. Under the push of the connecting rod 5, the sliders 6 on both sides can be made to slide inside the support tube 2, so that the far sides of the top plates 8 on both sides are in contact with the two sides of the inner wall of the bucket 1. At this time, the inside of the bucket 1 can be supported, and then the crank 12 is rotated, and the clamping plate 13 can be pushed out by the crank 12. When the clamping plate 13 contacts the outside of the bucket 1, the outside of the bucket 1 can be clamped. At this time, the bucket 1 can be repaired by welding, and the inner and outer walls of the bucket 1 are squeezed at the same time by the top plate 8 of the clamping plate 13, which can avoid the heat generated during welding causing the bucket 1 to deform and shift, thereby affecting the welding quality.
[0031] Reference Figure 1 and Figure 2 A mounting groove 14 is provided in the middle of the support tube 2 , and the slider 6 and the push rod 7 are both located inside the mounting groove 14 .
[0032] The mounting groove 14 can provide mounting space for the slide block 6 and the push rod 7 .
[0033] Reference Figure 1 , Figure 3 and Figure 4 The adjustment assembly includes a threaded column 15 and a second nut 16. The threaded column 15 is fixedly connected to the top surface of the card frame 11. The second nut 16 is threadedly connected to the top of the outer wall of the threaded column 15. The threaded column 15 passes through the connecting plate 10. The top surface of the connecting plate 10 contacts the top surface of the second nut 16. A sliding hole 17 is opened on one side of the connecting plate 10, and the threaded column 15 and the top of the outer wall of the card frame 11 are both inside the sliding hole 17.
[0034] By rotating the second nut 16, the two card frames 11 can be pulled to slide inside the connecting plate 10. At this time, the distance between the two card frames 11 can be adjusted. By reversing the second nut 16, the positions of the two card frames 11 inside the connecting plate 10 can be fixed. By adjusting the spacing between the two card frames 11, welds of different sizes can be adapted, thereby improving the practicality of the device.
[0035] Reference Figure 1 , Figure 2 and Figure 3 A connecting column 9 is fixedly connected to the top of the top plate 8 on one side, and the connecting column 9 passes through the other side of the middle of the connecting plate 10.
[0036] The connection plate 10 can be installed by inserting the connection plate 10 on the outer side of the connection column 9, so that the loading and unloading of the connection plate 10 becomes convenient, which is beneficial for use.
[0037] Reference Figure 1 and Figure 3 The top of the outer wall of the threaded rod 3 is threadedly connected with a first nut 18, and the first nut 18 is located above the connecting ring 4. The middle of the crank 12 is threadedly connected with a third nut 19, and one side of the third nut 19 contacts one side of the clamping frame 11. The outer side of the middle of the clamping plate 13 is fixedly connected with a guide rod 20, and the guide rod 20 is slidably connected with the clamping frame 11.
[0038] By rotating the first nut 18 to press it against the top of the connecting ring 4, the connecting ring 4 can be locked to prevent it from rotating in the opposite direction. By rotating the third nut 19 to press it against the outside of the clamping frame 11, the crank 12 can be locked to prevent it from rotating in the opposite direction.
[0039] Working principle: During use, when the bucket 1 needs to be welded and repaired, first place the support tube 2 inside the bucket 1, then rotate the threaded rod 3 to drive the connecting ring 4 to move downward, at this time the connecting ring 4 will push the connecting rod 5 to move, and under the push of the connecting rod 5, the sliders 6 on both sides can be squeezed out to slide inside the support tube 2, and at this time the two sliders 6 are away from each other, so the push rods 7 on both sides can be pushed out, and then the far sides of the top plates 8 on both sides can be made to contact the two sides of the inner wall of the bucket 1, at this time the interior of the bucket 1 can be supported, and then the first nut 18 is rotated to press it against the top of the connecting ring 4, at this time the connecting ring 4 can be locked to prevent it from rotating in reverse, and then the connecting plate 10 is picked up and inserted into the connecting column 9, and then the crank 12 is rotated, and the splint 13 can be moved by the crank 12 When the clamp 13 contacts the outer side of the bucket 1, the outer side of the bucket 1 can be clamped, and the bucket 1 can be welded and repaired, and the inner and outer walls of the bucket 1 can be squeezed at the same time by the top plate 8 of the clamp 13, so as to avoid the heat generated during welding causing the bucket 1 to deform and then shift. In use, the second nut 16 is rotated to separate it from the connecting plate 10. At this time, the two clamping frames 11 can be pulled to slide inside the connecting plate 10, and the distance between the two clamping frames 11 can be adjusted. The second nut 16 is reversed to press the connecting plate 10, and the position of the two clamping frames 11 inside the connecting plate 10 can be fixed. By adjusting the distance between the two clamping frames 11, it can adapt to welds of different sizes, thereby improving the practicality of the device.
