[0022] In this embodiment, when in use, the two bidirectional screw rods 3 are rotated, and the two support blocks 2 provide support force for the two bidirectional screw rods 3. The two groups of adjustment blocks 4 move away from each other under the action of the threads, and the four mounting parts 5 are separated. Then, the lever 21 is rotated in sequence according to the size of the pipeline. After the lever 21 is subjected to force, it slides inside the adjustment slide groove 11, and the adjustment plate 16 is driven to rotate inside the mounting part 5 through the support ring 20 and the slide rail 19, so that the corresponding length of the limit plate 18 moves to the extension line of one end of the fixed column 6, and then the pipeline is placed inside the two mounting parts 5, and the two bidirectional screw rods 3 are rotated in the opposite direction. The two support blocks 2 drive the two mounting parts 5 to approach each other, so that one end of the six fixed columns 6 fits with the outer surface of the pipe. After the fixed column 6 is subjected to force, the first spring 8 is squeezed through the push plate 7. The first spring 8 is compressed until one end of the fixed column 6 fits with the limit plate 18. The limit plate 18 limits the movement trajectory of the fixed column 6. The bidirectional screw rod 3 is continuously rotated to make the fixed column 6 push the push plate 7 to clamp the pipe tightly, so that the ends of the two pipes are quickly positioned concentrically, which is convenient for the installation and connection of the ports of the two pipes. The operation is simple and the structure is stable, which can ensure that the ports of the pipes remain aligned when they are misaligned.

[0023] Example 2

[0024] like Figure 1-4 As shown, the outer surface of the slide rail 19 is sleeved with a second spring 22, the inner wall surfaces of the four adjusting slide grooves 11 are each provided with three grooves 24, the outer surfaces of the four levers 21 are each fixedly connected to the limiting blocks 23, the outer surfaces of the four limiting blocks 23 are embedded in the inner wall surfaces of the corresponding four grooves 24, one side surface of the plurality of push plates 7 is each fixedly connected to the rubber pads 10, the plurality of rubber pads 10 are in the shape of an isosceles trapezoid, one side surface of the four mounting parts 5 is each fixedly connected to the three limiting collars 9, the outer surfaces of the plurality of fixing columns 6 match the plurality of limiting collars 9, the two ends of the two bidirectional screw rods 3 are each fixedly connected to the knobs 14, the outer surfaces of the four knobs 14 are each provided with a plurality of V-shaped grooves 15, the upper surface of the support plate 1 is provided with four guide slide grooves 12, the inner wall surfaces of the four guide slide grooves 12 are each embedded with sliders 13, and one side surface of the four sliders 13 is each fixedly connected to the lower surfaces of the four adjusting blocks 4.

[0025] In this embodiment, when the lever 21 is pushed, the lever 21 is subjected to downward pressure under the action of the arc surface of the limit block 23, driving the support ring 20 to slide on the outer surface of the slide rail 19, squeezing the second spring 22. When the lever 21 moves to another groove 24, the second spring 22 pushes the support ring 20, so that the limit block 23 fixed on the outer surface of the lever 21 is embedded in the groove 24, fixing the position of the lever 21, preventing the lever 21 from sliding when subjected to force, affecting the normal operation of the components, and multiple rubber pads 10 are released when the push plate 7 squeezes the pipeline. The pipe is deformed to increase the contact area between the pipe and the clamping part, and the friction between the pipe and the clamping part is effectively increased to prevent the pipe from sliding after being stressed. When the fixed column 6 moves, the limit collar 9 limits the moving trajectory of the fixed column 6 to prevent the fixed column 6 from shaking. The two-way screw rod 3 is rotated by the knob 14 to increase the force arm. The multiple V-shaped grooves 15 increase the friction between the fingers and the knob 14 to improve the user experience. When the four adjustment blocks 4 move, the slider 13 and the guide groove 12 cooperate to limit the moving trajectory of the four adjustment blocks 4 to prevent the four adjustment blocks 4 from shaking.

[0026] Working principle: Figure 1-4 As shown, when in use, the two bidirectional screw rods 3 are rotated, and the two support blocks 2 provide supporting force for the two bidirectional screw rods 3. The two groups of adjusting blocks 4 move away from each other under the action of the thread, and the four mounting parts 5 are separated. Then, the lever 21 is rotated in sequence according to the size of the pipeline. After the lever 21 is subjected to force, it slides inside the adjusting slide groove 11, and drives the adjusting plate 16 to rotate inside the mounting part 5 through the support ring 20 and the slide rail 19, so that the corresponding length of the limit plate 18 moves to the extension line of one end of the fixed column 6, and then the pipeline is placed inside the two mounting parts 5, and the two bidirectional screw rods 3 are rotated in the opposite direction. The two support blocks 2 drive the two mounting parts 5 to move closer to each other, so that one end of the six fixed columns 6 is fitted with the outer surface of the pipeline. After the fixed column 6 is subjected to force, the first spring 8 is squeezed through the push plate 7. The first spring 8 compresses the stroke until one end of the fixed column 6 is fitted with the limit plate 18. The limit plate 18 limits the movement trajectory of the fixed column 6, and the two bidirectional screw rods 3 are continuously rotated. The screw rod 3 is directed to make the fixed column 6 push the push plate 7 to clamp the pipe tightly. When pushing the lever 21, under the action of the arc surface of the limit block 23, the lever 21 is subjected to downward pressure, driving the support ring 20 to slide on the outer surface of the slide rail 19, squeezing the second spring 22. When the lever 21 moves to another groove 24, the second spring 22 pushes the support ring 20, so that the limit block 23 fixed on the outer surface of the lever 21 is embedded in the groove 24, fixing the position of the lever 21 to prevent the lever 21 from sliding when subjected to force, affecting the normal operation of the parts, and multiple rubber pads 10 are deformed when the push plate 7 squeezes the pipe. When the fixed column 6 moves, the limit collar 9 limits the moving trajectory of the fixed column 6 to prevent the fixed column 6 from shaking. The two-way screw rod 3 is rotated by the knob 14, and the multiple V-shaped grooves 15 increase the friction between the finger and the knob 14. When the four adjusting blocks 4 move, the slider 13 and the guide slide groove 12 cooperate to limit the moving trajectory of the four adjusting blocks 4.
