And a rotating handle is arranged at the tail end of the feeding screw rod.

That is, by rotating the feed screw, the clamp plate can be controlled to move in the direction of clamping the base. Thereby clamping the workpiece.

The clamp fixing part comprises a clamp fixing threaded sleeve and a clamp fixing screw rod, the clamp fixing threaded sleeve is integrally arranged on the outer side surface of the clamping foundation, and the clamp fixing screw rod is arranged in the clamp fixing threaded sleeve in a threaded connection mode.

Furthermore, the fixed foundation is in a disc form, and fixing holes are formed in the fixed foundation in an array mode so as to be convenient for fixing the fixed foundation on the platform or the plane;

the support bearing is arranged in the middle.

Further, the sliding arrangement of the clamping plate may take the following form: the bottom support upper surface has seted up the spout downwards, the clamp plate bottom is equipped with the slider that corresponds the spout.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use, low in cost and easy to maintain have solved prior art, and all sorts of problems that vice fastening work piece processing is limited through simple structure, and it is exactly like bottom sprag, press from both sides tight basis and clamp plate's three plane clamping structure provides more positive tight bases for the unformed work piece. The clamp part is arranged by rotating and is matched with the clamp fixing part, the orientation and the angle of a clamping workpiece can be flexibly adjusted, and the clamp can be better matched with mature existing machining tools such as bench drills, cutting machines and the like due to the fact that the fixing base is in a plane arrangement form.
