Compared with other embodiments, this embodiment is easier to adjust. In a preferred embodiment, at least three tension springs 9 are arranged between the first clamping member 5 and the second clamping member 7. The more tension springs 9 there are, the stronger the clamping force is. However, considering the balance of force and cost issues, generally three tension springs 9 are provided.

[0042] In a preferred embodiment, a guide structure is further provided between the first clamping member 5 and the second clamping member 7, and the guide structure includes an outer sleeve 8 and an inner sleeve 6, and the outer sleeve 8 and the inner sleeve 6 are slidably matched; the inner sleeve 6 is connected to the first clamping member 5, and the outer sleeve 8 is connected to the second clamping member 7. Furthermore, since the flange is circular, Figure 2-Figure 4 As shown, the shape of the conductor structure can be made into an arc shape to support the flange. When clamping the flange, only the left and right clamping forces need to be considered, and there is no need to worry about the flange falling off.

[0043] In a preferred embodiment, the tension spring 9 is arranged in the guide structure, such as Figure 5 As shown, a space is provided inside the outer sleeve 8 and the inner sleeve 6 for installing the tension spring 9.

[0044] In a preferred embodiment, the first clamping plate and the second clamping plate are arc-shaped plates. Figure 2 As shown, the first clamping member 5 and the second clamping member 7 are both provided with two arc-shaped plates, so that left-right and front-back movement is realized, and this structure exerts a more balanced force on the flange.

[0045] During use, the inner sleeve 6 can slide in the sliding cavity of the outer sleeve 8.

Through the setting of the tension spring 9, the inner sleeve 6 can be quickly reset when it slides, and the flange to be clamped can be clamped through the cooperation of the first clamping member 5 and the second clamping member 7 through the tension of the tension spring 9, which is convenient for adapting to flanges of different thicknesses and thus clamping and fixing flanges of different thicknesses. When the screw wheel 11 is rotated, the first screw 10 can be driven to rotate. When the first screw 10 rotates, it performs threaded motion with the adjustment seat 1 (it should be noted that in another solution, the first screw 10 can be set to be rotatably connected with the adjustment seat 1 (the first screw 10 can rotate in the adjustment seat 1 without relative movement), and is threadedly connected with the fixed seat 2). Due to the sliding fit between the sliding rod 12 and the matching groove on the fixed seat 2, the rotation of the first screw 10 can drive the adjustment seat 1 to move, so that the distance between the adjustment seat 1 and the fixed seat 2 can be adjusted. The utility model can adjust the distance between the two first clamping members 5 and the second clamping member 7. At this time, the guide protrusion of the slider 13 slides in the guide slide groove 16 of the adjustment groove 15 on the base 14, so as to adapt to flanges of different diameters and clamp and fix flanges of different diameters. When the turntable 18 is rotated, the bidirectional screw 17 can be driven to rotate. When the bidirectional screw 17 is rotated, it can perform threaded motion with the two bases 14. When the bidirectional screw 17 rotates and performs threaded motion with the two bases 14, the cross bar 19 and the two bases 14 are in sliding motion. The setting of the limit plate 20 can limit the movement distance of the base 14 and play a limiting role, so that the clamped flanges can be close to each other, the gap between the two flanges matches the valve body, the valve body and the pipeline are easier to connect together, and the installation efficiency of the staff is effectively improved.
