In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inside", The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation , are constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

As shown in FIGS. 1-2 , Embodiment 1, a precision clamp, includes a fixed clamp 1 and a movable clamp 2 , and the movable clamp 2 is clamped inside the fixed clamp 1 .

Embodiment 2, a precision clamp, comprising a fixed clamp 1 and a movable clamp 2, and the movable clamp 2 is clamped inside the fixed clamp 1;

The fixed pliers 1 is in the shape of an inverted "L". The fixed pliers 1 includes a vertical part and a horizontal part. There is a chamfer at the end, the tail end of the horizontal part is suspended, a chute is provided at the center of the horizontal part in the horizontal direction, and there are slideways on both sides of the horizontal part in the horizontal direction, and a movable clamp 2 is arranged in the chute and the slideway of the horizontal part; A through hole is formed through the center of the front surface and the rear surface of the horizontal part.

The movable pliers 2 includes an upper part and a lower part, the upper part is in the shape of a cuboid with an edge as an inclined plane, a "cross-shaped" clip slot is opened on one side of the upper part, and a connecting slot is arranged in the center of the upper slope; The middle position of the bottom surface of the upper part is fixedly connected with the lower part, and the shape of the lower part corresponds to the shape of the chute of the fixing clamp 1 and is clamped in the chute.

A connecting shaft 3 is arranged in the connecting groove of the movable pliers 2 .

This precision clamp uses the connecting shaft 3 to move the movable clamp 2 to move, so that the distance between the movable clamp 2 and the fixed clamp 1 is reduced until the device can be clamped; maintain device stability.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and does not deviate from the present invention.
