A rotating plate is rotatably connected to the side. A rotating shaft is rotatably connected to the middle of the rotating plate. A threaded post is fixedly connected to the bottom end of the rotating shaft. The threaded post extends through the bottom surface of the rotating plate. A driven worm gear is fixedly connected to the outer wall of the rotating shaft. Support ears are fixedly connected to both sides of one edge of the top surface of the rotating plate. An adjusting worm is rotatably connected to the top surface of the rotating plate through the support ears. The middle part of the adjusting worm meshes with the driven worm gear.

[0006] Preferably, in any of the above embodiments, both the lower and upper clamps are semi-circular rings, the lower and upper clamps have the same diameter, and the inner walls of both the lower and upper clamps are fixedly connected with anti-slip pads.

[0007] The technical effect achieved by adopting the above solution is that the lower half clamp and the upper half clamp can effectively clamp the pipe from top to bottom, and the anti-slip pad improves the stability of the clamping.

[0008] Preferably, in any of the above embodiments, the position of the threaded post corresponds to the position of the strip-shaped bayonet, the diameter of the threaded post is adapted to the width of the inner wall of the strip-shaped bayonet, and both the threaded post and the strip-shaped bayonet correspond to the middle position of the positioning frame.

[0014] This utility model has the following advantages:

[0015] 1. This anti-loosening grooved clamp structure works by interlocking the lower and upper clamp halves, then flipping the flip plate downwards to push the guide clamping plate into the positioning frame. Rotating the adjusting worm gear drives the driven worm wheel, which in turn rotates the shaft and threaded column, pushing the guide clamping plate upwards. This causes the flip plate and the clamping plate to press together, securing one end of the lower and upper clamp halves. After fixing, the adjusting worm gear and driven worm wheel are locked to prevent the shaft from loosening and rotating. Furthermore, the positioning frame restricts the rotation of the guide clamping plate, effectively limiting rotation.

[0016] 2. This anti-loosening grooved clamp structure, through the threaded column and rotating shaft, is rotatably connected to the flip plate, which can connect the threaded column to the main body to prevent it from falling off, so as to form a whole, reduce the number of separate parts, and facilitate disassembly and assembly.

An upper clamp 2 is rotatably connected to the lower clamp 1 via the connecting hinge 3. A snap-fit ​​plate 10 is fixedly connected to the top end of the lower clamp 1 away from the connecting hinge 3. A strip-shaped notch 14 is provided in the middle of one side of the snap-fit ​​plate 10. A positioning frame 11 is fixedly connected to the middle of the bottom surface of the snap-fit ​​plate 10. A connecting plate 4 is fixedly connected to the end of the upper clamp 2 away from the connecting hinge 3. A flip-type clamp is rotatably connected to one side of the connecting plate 4. A rotating plate 5 is rotatably connected to a rotating shaft 6 in the middle. A threaded post 13 is fixedly connected to the bottom end of the rotating shaft 6. The threaded post 13 extends through the bottom surface of the rotating plate 5. A driven worm gear 7 is fixedly connected to the outer wall of the rotating shaft 6. Support ears are fixedly connected to both sides of one edge of the top surface of the rotating plate 5. An adjusting worm 8 is rotatably connected to the top surface of the rotating plate 5 through the support ears. The middle part of the adjusting worm 8 is engaged with the driven worm gear 7. A guide clamping plate 12 is threadedly connected to the outer wall of the threaded post 13. The guide clamping plate 12 can slide and guide against the inner wall of the positioning frame 11.

[0024] As an optional technical solution of this utility model: both the lower half clamp 1 and the upper half clamp 2 are semi-circular rings, the lower half clamp 1 and the upper half clamp 2 have the same diameter, and the inner walls of both the lower half clamp 1 and the upper half clamp 2 are fixedly connected with anti-slip pads, so that the lower half clamp 1 and the upper half clamp 2 can effectively clamp the pipe from top to bottom, and the stability of the clamping is improved by the anti-slip pads.

[0025] As an optional technical solution of this utility model: the position of the threaded post 13 corresponds to the position of the strip-shaped bayonet 14, the diameter of the threaded post 13 is adapted to the width of the inner wall of the strip-shaped bayonet 14, and both the threaded post 13 and the strip-shaped bayonet 14 correspond to the middle position of the positioning frame 11, so that the threaded post 13 can be effectively pushed into the interior of the strip-shaped bayonet 14.

[0026] As an optional technical solution of this utility model: the bottom position of the threaded column 13 corresponds to the bottom position of the positioning frame 11, and the size of the guide clamping plate 12 is adapted to the size of the inner wall of the positioning frame 11, so that the positioning frame 11 can effectively guide and slide with the guide clamping plate 12, thereby improving the stability of the clamping adjustment.

[0027] As an optional technical solution of this utility model: both ends of the adjusting worm 8 have support ears extending through them, and both ends of the adjusting worm 8 are fixedly connected to rotating heads 9. The adjusting worm 8 can be easily rotated and adjusted by rotating heads 9, and it is convenient to tighten it with a wrench.

[0028] The working process of this utility model is as follows: When the user uses it...

[0029] 1) After the lower half clamp 1 and the upper half clamp 2 are fastened together, the flip plate 5 is flipped down so that the guide clamping plate 12 is pushed into the interior of the positioning frame 11.

[0030] 2) Then, by rotating the adjusting worm 8, the driven worm wheel 7 is driven to rotate, which in turn drives the rotating shaft 6 and the threaded column 13 to rotate, driving the guide clamping plate 12 to push upward, so that the guide clamping plate 12 is pressed upward;

[0031] 3) This causes the flip plate 5 and the snap plate 10 to press together vertically, thereby achieving mutual pressing and fixing of the lower half clamp 1 and the upper half clamp 2 at one end.

[0032] In summary, this utility model, by interlocking the lower clamp 1 and the upper clamp 2, and then flipping the flipping plate 5 downwards, pushes the guide clamping plate 12 into the positioning frame 11. Then, by rotating the adjusting worm gear 8, the driven worm wheel 7 is driven to rotate, which in turn drives the rotating shaft 6 and the threaded column 13 to rotate, pushing the guide clamping plate 12 upwards and pressing it against the rotating plate 5 and the snap-fit ​​plate 10. This achieves mutual clamping and fixing of one end of the lower clamp 1 and the upper clamp 2. After fixing, the adjusting worm gear 8 and the driven worm wheel 7 are locked to prevent the rotating shaft 6 from loosening and rotating. Furthermore, the positioning frame 11 restricts the rotation of the guide clamping plate 12, effectively limiting rotation. The threaded column 13 and the rotating shaft 6 are rotatably connected to the flipping plate 5, allowing the threaded column 13 to connect to the main body and preventing it from falling off. This creates a unified whole, reducing the number of separate parts and facilitating disassembly and assembly.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
