The angle of the circle where the C-shaped bracket 2 is located is greater than 180° and less than 270°. In this embodiment, the angle of the circle where the C-shaped bracket 2 is located is 228°, and a coaxial semi-cylinder 3 is rotatably installed in the C-shaped bracket 2. The angle of the circle where the semi-cylinder 3 is located is the same as the angle of the circle where the C-shaped bracket 2 is located. The semi-cylinder 3 can rotate continuously in the C-shaped bracket 2, and a plurality of dovetail sliders 12 are fixedly installed on the semi-cylinder 3. The C-shaped bracket 2 is provided with a corresponding dovetail groove 13, and the dovetail slider 12 is slidably installed in the corresponding dovetail groove 13. A U-shaped groove 4 is provided on the semi-cylinder 3, and the arc circle of the U-shaped groove 4 is coaxially arranged with the semi-cylinder 3. A coaxial tooth groove 5 is provided on the outer periphery of the semi-cylinder 3, and the front and rear sides of the tooth groove 5 are respectively meshed with a first gear 6, and the tooth groove 5 will at least keep meshing with one first gear 6. The first gear 6 is rotatably mounted on the support rod 7 through a one-way bearing, the inner ring of the one-way bearing is fixedly connected to the support rod 7, the outer ring of the one-way bearing is fixedly connected to the first gear 6, the support rod 7 is mounted on the base 1, and sliding rods 8 are fixedly mounted on both sides of the base 1, and both ends of the sliding rod 8 are fixedly connected to the base 1 through vertical rods, and sliding blocks 9 are slidably mounted on the sliding rod 8. Through holes are provided on the sliding blocks 9, and the sliding rod 8 slides and contacts with the inner walls of the corresponding through holes. The bottom of the sliding block 9 slides and contacts with the base 1 to prevent the sliding block 9 from rotating, the support rod 7 is fixedly connected to the sliding block 9, and the sliding block 9 is elastically connected to the sliding block 8 through a first spring 10, the first spring 10 is sleeved on the sliding block 8, one end of the first spring 10 is fixedly connected to the sliding block 8, and the other end of the first spring 10 is fixedly connected to the sliding block 9, and the two sides of the base 1 are respectively connected to one end of a winding rope 11, and the other end of the winding rope 11 is connected to the corresponding side of the semi-cylinder 3. The present invention has a simple structure and an ingenious design. The pipeline is fixed by the winding rope 11, which avoids collision between metal hard objects and is not easy to generate noise. The flexibility of the winding rope 11 can play a role of buffering and shock absorption, and can reduce the transmission of vibration, thereby reducing the propagation of noise; the winding rope 11 can also be used to fix pipelines of different diameters, and has a wider range of applications; the winding rope 11 is spirally wound around the pipeline, and the clamping force of the winding rope 11 on the pipeline is more evenly distributed; when the pipeline is subjected to axial force, the winding rope 11 on one side will be tightened, which can prevent the pipeline from continuing to move, can meet actual needs, and is suitable for promotion.When in use, the base 1 is installed at the desired position, and then the pipe is placed in the U-shaped groove 4, and then the semi-cylinder 3 is rotated. The semi-cylinder 3 rotates and pulls one end of the winding rope 11 on both sides to revolve around the pipe, and the other end of the winding rope 11 does not move, so that the winding rope 11 can be close to pipes of different sizes. The winding rope 11 is spirally wound on the pipe, and the winding directions of the winding ropes 11 on both sides are opposite, until the winding rope 11 is completely wound around the pipe, and the pipe is fixed; the winding directions of the winding ropes 11 on both sides are opposite. When the pipe is subjected to axial force, the pipe moves, and the winding of the winding rope 11 on one side on the pipe becomes loose, and the winding rope 11 on the other side becomes tighter due to the tension, thereby increasing the fixation of the pipe, thereby preventing it from continuing to move, and playing a role in buffering the axial force; the winding rope 11 is spirally wound on the pipe, and each circle of the winding rope 11 has a similar winding force on the pipe. , which can share the force more evenly; since the winding rope 11 is flexible, the contact between the winding rope 11 and the pipeline is soft contact, which will not produce collision noise, and is not conducive to the transmission of noise, and the noise is smaller; when the semi-cylinder 3 rotates, the first gear 6 rotates under the meshing with the tooth groove 5, and the first gear 6 can only rotate in one direction under the action of the one-way bearing, so that the rotated semi-cylinder 3 maintains the state and avoids its reset. When it is necessary to reset the semi-cylinder 3 to release the winding of the winding rope 11, the slider 9 is pushed, and the first spring 10 is compressed, so that the slider 9 drives the first gear 6 to disengage from the tooth groove 5, so that the semi-cylinder 3 loses its restriction and can be rotated in the opposite direction to reset. After the semi-cylinder 3 is reset, the slider 9 is reset under the action of the first spring 10, and drives the first gear 6 to move until it meshes with the tooth groove 5 again, and the semi-cylinder 3 can only rotate in one direction again.

[0016] Specifically, if Figure 1 , Figure 8 As shown, support rods 20 are respectively installed at both ends of the semi-cylinder 3 described in this embodiment, and the two support rods 20 are symmetrically distributed on the left and right. A through groove 21 is provided on the support rod 20, and the winding rope 11 passes through the corresponding through groove 21. The winding rope 11 cannot move from the through groove 21. A limiting portion is provided at the other end of the winding rope 11, and a groove 22 is provided in the through groove 21. A pressure block 24 is installed in the groove 22 through several second springs 23. One end of the second spring 23 is fixedly connected to the inner wall of the groove 22, and the other end of the second spring 23 is fixedly connected to the pressure block 24. The pressure block 24 presses the corresponding winding rope 11. The semi-cylinder 3 drives the support rod 20 to rotate together, so that when the winding rope 11 is wound around the pipe, the winding rope 11 and the pressing block 24 are in sliding contact and cooperation. The pressing block 24 presses the winding rope 11 under the elastic force of the second spring 23. The winding rope 11 is subjected to a pre-tightening force, so that it fits more tightly with the pipe, and the winding rope 11 will not loosen. It is equivalent to a person tightening the winding rope 11 around the pipe by hand, which has a better winding effect and can more stably grasp the pipe.

[0017] Specifically, Figure 1 , Figure 5, Figure 7 As shown, in the present embodiment, thread grooves are respectively provided on the support rod 20, and the screw rod 30 is installed with threaded cooperation. Circular slide grooves 31 communicating with the outside are respectively provided on both sides of the semi-cylinder 3. The support rod 20 is slidably installed in the corresponding circular slide grooves 31. The support rod 20 can only slide in the circular slide grooves 31 and cannot rotate. Several guide blocks 32 are respectively fixedly installed on the support rod 20. Corresponding guide slide grooves 33 are provided on the side walls of the circular slide grooves 31. The guide blocks 32 are slidably installed in the corresponding guide slide grooves 33. The screw rod 30 is rotatably installed in the circular slide grooves 31 through bearings. A coaxial second gear 34 is respectively fixedly installed on the screw rod 30. An arcuate rack 35 is meshed and cooperated on one side of the second gear 34. The circle where the centers of the two second gears 34 are located, the arcuate rack 35, and the semi-cylinder 3 are coaxially arranged. The arcuate rack 35 is fixedly installed on the C-shaped bracket 2, and an avoidance groove for avoiding the arcuate rack 35 is provided on the semi-cylinder 3. When the semi-cylinder 3 rotates forward, it drives the support rod 20 and the screw rod 30 to rotate together, so that the second gear 34 rotates when meshing with the arc-shaped rack 35, thereby driving the screw rod 30 to rotate. The rotation of the screw rod 30 causes the support rod 20 to slide in a direction close to each other, and the support rod 20 drives the winding rope 11 to move, so that the winding rope 11 is more evenly wound on the pipe, so that the winding rope 11 is more evenly stressed to avoid accumulation in one place; when the semi-cylinder 3 rotates reversely, the support rod 20 slides in a direction away from each other.

[0018] Further, such as Figure 1 , Figure 2 , Figure 4 As shown, two U-shaped support plates 40 are fixedly installed on the base 1 of this embodiment, and the two U-shaped support plates 40 are symmetrically distributed. The U-shaped support plates 40 are fixed on the base 1 through columns, and the C-shaped bracket 2 is located between the two U-shaped support plates 40. Elastic rubber pads 41 are fixedly installed on the U-shaped support plates 40, and the elastic rubber pads 41 are also U-shaped. One end of the winding rope 11 is fixedly connected to the U-shaped support plate 40. The U-shaped support plate 40 provides support for the pipeline, and the elastic rubber pad 41 can avoid wear between the pipeline and the U-shaped support plate 40, and also has a certain buffering effect to reduce the transmission of noise.

[0019] Furthermore, Figure 2 As shown, the base 1 of this embodiment is fixed with a plurality of mounting holes 50, and the mounting holes 50 are countersunk holes. The mounting holes 50 are used to conveniently fix the device at a desired position.

[0020] Furthermore, Figure 2 , Figure 6 As shown, in this embodiment, several handles 60 are fixedly mounted on the semi-cylinder 3. Rotating the semi-cylinder 3 by the handles 60 is more convenient and labor-saving.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
