The movable ring meshes with the pinion, the shaft of the pinion is keyed to one end of the lead screw, the other end of the lead screw is threaded to the inside of the threaded cylinder, the clamping plate is bolted to the threaded cylinder, and there are two stabilizing rods, which are bolted to the clamping plate.

[0011] The fixing mechanism is connected to the clamping ring of the EDM machine head. The movable ring drives the four clamping plates to move. The four clamping plates can clamp and fix the copper material inside the inner cylinder to complete the installation of the copper material. When it is necessary to remove it, the movable ring is rotated in the opposite direction, and the four clamping plates will be released.

The fixing bolts pass through the holes of the two connectors. The EDM machine head clamp ring is fitted onto the EDM machine, then the arc-shaped hoops are fitted, and the fixing bolts are inserted into the connectors of the arc-shaped hoops. The nut of the fixing bolts is rotated, tightening the arc-shaped hoops to apply pressure to the four inner elastic plates, thus firmly fixing the elastic plates to the EDM machine.

[0013] As a preferred embodiment of this utility model, the inner side of the elastic plate is provided with anti-slip texture, and the arc-shaped hoop is fixed to the elastic plate by a fixing bolt. The anti-slip texture of the elastic plate facilitates the fixing of the elastic plate.

[0014] As a preferred embodiment of this utility model, the screw hole on the surface of the movable ring is threaded with a tension bolt, which contacts the clamp and can fix the movable ring on the surface of the clamp.

[0015] As a preferred embodiment of this utility model, the surface of the clamp is bolted with anti-slip strips, and four anti-slip strips are provided. The anti-slip strips make it convenient for the user to grip the clamp and rotate the movable ring.

[0016] In a preferred embodiment of this utility model, the surface of the lead screw is rotatably sleeved with the hole of the clamp, the surfaces of the threaded cylinder and the stabilizer are slidably connected with the hole of the inner cylinder, the lead screw is rotatably set with the clamp through a bearing to ensure the smoothness of the lead screw rotation, and the threaded cylinder and the stabilizer are slidably set with the inner cylinder through a slide rail to guide the threaded cylinder and the stabilizer.

[0017] Beneficial effects:

[0018] 1. Insert the copper material into the inner cylinder of the clamp, rotate the movable ring, the movable ring can drive the four small gears to rotate, the small gears can drive the lead screw to rotate, the lead screw can drive the threaded cylinder to move, the threaded cylinder can drive the clamping plate to move, and the stabilizing rod guides and stabilizes the clamping plate.

[0019] 2. Place the EDM machine head clamp ring onto the EDM machine, then put on the arc-shaped hoop, insert the fixing bolt into the connector of the arc-shaped hoop, rotate the fixing arc-shaped hoop, and firmly fix the elastic plate onto the EDM machine.

[0020] In this invention, the movable ring drives the four clamping plates to move. The four clamping plates can clamp and fix the copper material inside the inner cylinder, thus completing the installation of the copper material. When it is necessary to remove it, the movable ring is rotated in the opposite direction, and the four clamping plates will be released from their clamping state. Attached Figure Description
