A sliding cavity 12 is arranged in the fixing clamp 1, and the sliding cavity 12 is used for the sliding rod 5 to pass through.

As shown in fig. 2, the fixing clip 1 has a first holding surface 11, and the first holding surface 11 is provided on a side surface of one end of the slide chamber 12. The movable clamp 2 is provided with a second clamping surface 21 opposite to the first clamping surface 11, and the second clamping surface 21 is arranged at the top end of a boss 22 which extends outwards. The distance between the second clamping surface and the first clamping surface 11 can be adjusted by pressing one end of the elastic piece 4 of the fixed clamp 1 and the movable clamp 2.

As shown in fig. 3, the sliding cavity 12 of the fixing clip 1 is suitable for allowing an object to be clamped to pass through, and then the distance between the second clamping surface 21 and the first clamping surface 11 is adjusted, so that the second clamping surface 21 is pressed on the upper surface of the clamped object, the clamped object is clamped between the first clamping surface 11 and the second clamping surface 21, meanwhile, the clamped object is limited in the sliding cavity 12, the limit of the sliding cavity 12 also plays a clamping role, the clamping area and the clamping force are increased, the clamped object is effectively prevented from shaking relative to the adjusting clamp, and the clamped object is more stable.

Specifically, as shown in fig. 2 and 3, the first clamping surface 11 is located on an inner wall surface at one end of the sliding cavity 12, and an opening is provided on a side wall of the fixing clip 1 opposite to the first clamping surface 11; the movable clamp 2 is provided with a boss 22 extending outwards.

Thus, at least one plane is formed in the sliding cavity 12, so that the sliding rod 5 penetrating through the sliding cavity can be positioned, and the sliding rod 5 is prevented from rotating along the axial direction.

In addition, the shape of the inner wall surface of the sliding cavity 12 may also be any other shape, for example, the number of the inner wall surfaces may be three, four, five, six, etc., all the inner wall surfaces may be a plane, or an arc surface or other shapes, or a combination of a plane and an arc surface; or the inner wall surface of the sliding cavity 12 is a complete arc surface or other shapes, as long as the shape of the inner wall surface of the sliding cavity 12 is matched with the shape of the outer wall surface of the object to be clamped, so that the object to be clamped can be limited and clamped to a certain extent. The first clamping surface 11 can also be in any shape outside the plane, and the second clamping surface 21 can be in any shape outside the plane and the arc surface, as long as the shapes of the outer surfaces of the first clamping surface 11 and the second clamping surface 21 are matched with those of the clamped object, so that the clamped object can be stably clamped between the first clamping surface 11 and the second clamping surface 21.

As shown in fig. 1, the middle parts of the fixed clamp 1 and the movable clamp 2 are respectively provided with a first connecting part and a second connecting part, and the rotating shaft 3 penetrates through the first connecting part and the second connecting part to enable the fixed clamp 1 and the movable clamp 2 to form rotating connection; the adjustment jig further includes an elastic member 4, for example, a spring, provided between the fixed clip 1 and the movable clip 2, the elastic member 4 being provided on an end of the movable clip 2 opposite to the second holding surface 21, the end of the movable clip 2 being referred to as a first end of the movable clip 2 for convenience of description, the end where the boss 22 is located being a second end, both ends of the elastic member 4 being fixed to the fixed clip 1 and the movable clip 2, respectively, the elastic member 4 holding the first holding surface 11 and the second holding surface 21 in a biasing force to approach each other.
