The tension spring grooves 5 1 is provided with a tension spring 4, and the two ends of the tension spring 4 are interlocked to lock the multiple groups of modules 5. By setting the positioning seat 1 and the pressure plate 2, the positioning seat 1 and the pressure plate 2 are fixedly connected by bolts 3 and the module 5 is clamped and fixed. By setting the tension spring 4, the tension spring 4 is used in conjunction with the positioning seat 1 to further fix the module 5, effectively improving the effect of fixing the module 5, and the operation is simple, improving the efficiency of repairing the module 5, and while fixing the module 5, the α angle of the module 5 is not blocked, and the α angle can be processed, further improving the efficiency of repairing the module 5.

[0032] The positioning seat 1 includes a bottom plate 11, a support column 12 is fixedly connected to the top of the bottom plate 11, and an inner support plate 13 is fixedly connected to the top of the support column 12. The bottom plate 11, the support column 12 and the inner support plate 13 are fixed by welding. The bottom plate 11 and the inner support plate 13 are both circular ring structures, and the bottom plate 11 and the inner support plate 13 are coaxially arranged, wherein the bottom plate 11 is composed of a bottom ring, a middle ring and a top ring, the outer diameter of the bottom ring is greater than the outer diameter of the middle ring, the outer diameter of the middle ring is greater than the outer diameter of the top ring, and the outer diameter of the top ring is adapted to the curvature of the inner wall of the module 5. By setting the bottom plate 11, when in use, the module 5 is placed above the bottom ring of the bottom plate 11, and the inner side wall of the module 5 is abutted against the top ring of the bottom plate 11, wherein the bottom ring of the bottom plate 11 supports the module 5 and cooperates with the pressure plate 2 to clamp and fix the module 5 vertically, and the top ring of the bottom plate 11 cooperates with the tension spring 4 to clamp and fix the module 5 horizontally, thereby improving the stability of the module 5 and making the clamping effect of the tooling on the module 5 better.

[0033] The outer wall of the inner support plate 13 is in a V-shaped structure. When the module 5 is installed between the positioning seat 1 and the pressure plate 2, the outer wall of the inner support plate 13 is in close contact with the inner wall of the module 5. By setting the inner support plate 13, when in use, the module 5 is abutted against the inner support plate 13, so that the inner support plate 13 and the top ring in the bottom plate 11 are abutted against one side of the module 5 together, and the module 5 is clamped in cooperation with the tension spring 4. The inner support plate 13 and the bottom plate 11 are respectively abutted against the upper and lower parts of the module 5, thereby increasing the force points and further improving the stability of the module 5.

The outer diameter of the screw 24 is adapted to the inner diameter of the inner support plate 13. By setting the screw 24, the pressing plate 2 cooperates with the positioning seat 1 through the screw 24, which effectively reduces the tightening action and improves the assembly efficiency compared to the use of bolts 3 for fixing. The handle 22 is a Y-shaped structure, and the handle 22 is made of bent steel bars. By designing the handle 22 with a Y-shaped structure, when tightening the pressing plate 2, it is convenient for the user to exert force and reduce the difficulty of installation.

The upper opening of the positioning groove 15 is adapted to the support column 12. By providing the positioning groove 15, it is convenient to quickly find the positioning point when welding the support column 12 to the bottom plate 11, thereby improving the welding efficiency.

[0039] The working principle of the utility model is as follows: when in use, for embodiment one, first place the module 5 on the bottom plate 11, and the inner side surface of the module 5 abuts against the bottom ring on the bottom plate 11, and the inner side surface of the module 5 abuts against the side wall of the inner support plate 13. After the module 5 is installed, the pressure plate 2 is screwed and fixed to the inner support plate 13 by bolts 3, and the module 5 is compressed to the greatest extent, and then the tension spring 4 is embedded in the tension spring groove 51 and the two ends of the tension spring 4 are interlocked, and the module 5 is locked and pressed against the inner support plate 13 by the tension spring 4 to increase the fixing effect of the module 5.

[0040] For the second embodiment, after the module 5 is installed between the base plate 11 and the pressing plate 2, the pressing plate 2 is rotated by the handle 22 to bring the base plate 11 closer, and the pressing plate 2 is screwed and fixed to the inner support plate 13 to press the module 5 to the maximum extent.
