The utility model discloses further set up to: the base is provided with a fixing groove for inserting one end of a workpiece, the end, inserted into the fixing groove, of the workpiece is provided with three blind holes, the hole wall of each blind hole is provided with internal threads, the three blind holes are respectively opposite to the first core rod, the second core rod and the third core rod, the three blind holes respectively extend into the first core rod, the second core rod and the third core rod, and one side, far away from the workpiece, of the base is provided with a screw rod inserted into the blind hole.
Through adopting above-mentioned technical scheme, keep away from one side of machined part with the screw rod by the base and insert to the blind hole in, for ordinary single screwed connection, the screw rod all is fixed in the base with first core bar, second core bar and third core bar, and is more firm, has reached the more firm purpose of magnetic core processing mould. But when the user uses this product and damages the machined part, only need not hard up the screw and pull down the machined part, change new machined part can, more economic environmental protection.
The utility model discloses further set up to: the blind hole bottom is equipped with the dead lever, and the external screw thread has been arranged to the dead lever outer wall, and the one end that the screw rod was inserted to the blind hole is equipped with the locking hole, and the downthehole internal thread that is arranged of locking, dead lever insert to the locking downthehole.
Through adopting above-mentioned technical scheme, dead lever and blind hole bottom body coupling, when the user inserts the screw rod in the blind hole, not only the outer wall and the blind hole inner wall of screw rod pass through threaded connection fixedly, and the locking hole in the screw rod passes through threaded connection fixedly equally with the dead lever, and for the outer wall and the blind hole inner wall threaded connection that only singly pass through the screw rod, more firm has reached the more firm purpose of magnetic core mold processing.
