the fixture body is arranged on the upper side of the connecting disc and used for bearing a workpiece;

the mandrel is arranged on the surface of the clamp body;

the plurality of studs are arranged between the transition disc and the fixture body, and two ends of the studs are respectively fixedly connected with the transition disc and the fixture body;

the bottom ends of the pull rods are fixedly connected with the connecting disc, and the top ends of the pull rods penetrate through the clamp body and can move up and down in the clamp body;

and the pressing plate is arranged at the top end of the pull rod and used for fixing the workpiece.

Further, the studs and the pull rods are arranged at intervals.

Further, a backing plate is arranged on the surface of the clamp body.

Furthermore, the backing plate is correspondingly arranged right below the pressing plate.

Further, pull rod upper portion cover is equipped with a spring, and the spring upside is provided with a connecting cap, connects the cap to fix on the pull rod top, connects the cap side and links to each other with the clamp plate is fixed, the spring both ends respectively with connect cap bottom and the inconsistent connection in anchor clamps body surface.

Furthermore, the connecting block is fixedly connected with the connecting disc through a connecting shaft.

The utility model has the advantages that: the utility model discloses a connection pad, connecting block that set up and be connected and the position relation between the anchor clamps body with transition dish, the up-and-down motion that drives the clamp plate through the motion of connection pad realizes pressing from both sides tightly and the release to the work piece, and it is more firm to press from both sides tight effect, overall structure is simple moreover, convenient operation.
