In a further technical scheme, an annular bulge is formed on the inner wall of the rotating disc outer sleeve, and a strip-shaped arc-shaped groove is formed at the top of the annular bulge; the rotating disc is provided with a column opposite to the arc-shaped groove, one end of the column is fixedly connected with the rotating disc, the other end of the column extends into the arc-shaped groove, and the rotating angle of the rotating disc is limited through the arc-shaped groove.
In a further embodiment, the clamping end is designed in the form of an irregular circular arc.
After adopting the structure, compared with the prior art, the utility model has the advantages that:
the chuck of this application presss from both sides tight work piece through three cubic jack catch, in operation, rotatory driving disk clockwise rotation can drive three jack catch and inwards gather together the self-holding work piece, rotatory driving disk anticlockwise rotation can drive three jack catch and outwards expand and loosen the work piece, replace traditional lock anchor clamps and drive the work piece clamping mode, the clamping is efficient, moreover, the radian change that this application utilized the tight end of clamp of three jack catch realizes the high accuracy location of work piece, the centre gripping scope is big.
The utility model is further illustrated with reference to the following figures and examples.
