[0007] Both of the through holes on the connecting body are rectangular holes, and the length direction of the holes is set as the left-right direction.

[0008] The end part of the rotating shaft is relatively fixed to the connecting body by means of a riveting process.

[0009] A sunken activity groove is provided on the inner side surface of the movable member, and the torsion spring is fitted in the activity groove.

[0010] The saw teeth are arranged at equal intervals along the left-right direction.

[0011] The main body of the movable component is a fan-shaped block, the serrations are formed at one end of the fan-shaped block, and the pressing plate is integrally connected to the other end of the fan-shaped block.

[0012] Preferably, the left and right side walls of the movable cavity are provided with first shaft holes for the rotating shaft to pass through, and the left and right side walls of the sector block are provided with a second shaft hole for the rotating shaft to pass through.

[0013] The end wall of the movable cavity away from the arc surface is provided with an inclined surface for the end of the torsion spring to abut or connect.

[0014] The moving part is made of metal.

[0015] After adopting the above technical solution, the present invention has the following technical effects:

[0016] This invention improves upon existing D-ring buckles by employing a torsion spring to drive a movable component, causing its serrations to tightly engage with the curved surface. This secures the strip-shaped component (back strap, pull strap, etc.) wrapped around the perforation and curved surface. When the user needs to adjust the length, simply pressing the pressing plate of the movable component unlocks the serrations from their limiting position on the strip-shaped component. After adjustment, the movable component automatically resets under the elastic force of the torsion spring, continuing to lock the strip-shaped component. This invention offers convenient operation and a better user experience when implementing the adjustment function, and is also suitable for scenarios where only one-handed operation is possible.

Detailed Implementation

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] refer to Figures 1 to 4 As shown, this utility model discloses an adjustment clamp, including a connecting body 1, a rotating shaft 2, a movable part 3, and a torsion spring 4;

[0025] Both ends of the connecting body 1 are provided with through holes 11 and 11' for threading ropes, and a movable cavity 12 is provided between the two through holes 11 and 11'; an arc surface 13 is provided on the end wall of the movable cavity 12 near one of its through holes 11.

[0026] The two ends of the rotating shaft 2 are respectively connected to the left and right side walls of the movable cavity 12;

[0027] The movable part 3 is rotatably sleeved on the rotating shaft 2. A number of serrations 31 are provided at the end of the movable part 3 near the arc surface 13, and a pressing plate 32 is provided at the end of the movable part 3 away from the arc surface 13. The pressing plate 32 is movably fitted on the outside of the movable cavity 12, that is, not inside the movable cavity 12.

[0028] The torsion spring 4 is sleeved on the rotating shaft 2, with its two ends abutting against the end wall of the movable cavity 12 and the movable part 3, respectively, to provide elastic force so that the saw teeth 31 return to the direction of the arc surface 13; by pressing the pressing plate 32, the saw teeth 31 are disengaged from the arc surface 13, and the torsion spring 4 is compressed at the same time.

[0029] Through the above solution, this utility model improves upon the existing D-ring buckle by using a torsion spring 4 to drive the movable part 3 so that its serrations 31 are tightly fitted onto the arc surface 13, thereby fixing the strip a (back strap, pull strap, etc.) wrapped around the perforation 11 and the arc surface 13. When the user needs to adjust the length, simply press the pressing plate 32 of the movable part 3 to unlock the serrations 31 from limiting the strip a. After adjustment, the movable part 3 can automatically reset under the elastic force of the torsion spring 4 to continue locking the strip a. This utility model is convenient to operate when implementing the adjustment function, provides a better user experience, and is also suitable for some scenarios where only one-handed operation is possible.
