The lower part of the foot pedal rod 501 is fixedly connected to one end of the linkage rod 502. The other end of the linkage rod 502 passes through the fixed sleeve 4 and is fixedly connected to the clamping piece 3. The fixed sleeve 4 restricts the movement direction of the linkage rod 502, restricting the linkage rod 502 to only move back and forth. Press down the foot pedal rod 501, and the foot pedal rod 501 pushes the linkage rod 502 to drive the clamping piece 3 to move forward; lift the foot pedal rod 501, and the foot pedal rod 501 drives the linkage rod 502 to move backward. At this time, the clamping piece 3 moves backward together.

[0021] In this embodiment, both the clamping piece 3 and the positioning piece 2 are arranged in an arc shape, and the opening shape is adapted to the bottom shape of the ceramic core workpiece. The opening direction of the positioning piece 2 is opposite to the opening direction of the clamping piece 3.

[0022] During use, place the ceramic core workpiece vertically on the base 1, and the bottom of the workpiece fits against the open end of the positioning piece 2.

The lower part of the foot pedal rod 501 is fixedly connected to one end of the linkage rod 502. The other end of the linkage rod 502 passes through the fixed sleeve 4 and is connected and fixed to the clamping piece 3. The fixed sleeve 4 restricts the movement direction of the linkage rod 502, restricting the linkage rod 502 to only move back and forth. Press down the foot pedal rod 501, and the foot pedal rod 501 pushes the linkage rod 502 to drive the clamping piece 3 to move forward; lift the foot pedal rod 501, and the foot pedal rod 501 drives the linkage rod 502 to move backward. At this time, the clamping piece 3 moves backward together.

[0026] During use, select the appropriate clamping piece 3 and positioning piece 2 according to the size of the ceramic core workpiece. Vertically place the ceramic core workpiece on the base 1 on one side of the selected positioning piece 2, and the bottom of the workpiece fits with the open end of the selected positioning piece 2. Step on the foot pedal rod 501 to push the clamping piece 3 forward to firmly clamp the workpiece. Fine-tuning is required according to the actual situation to ensure that the clamping force is uniform and just right. The clamped workpiece is drilled according to needs. After drilling is completed, lift the foot pedal rod 501 to loosen the workpiece, take out the workpiece, and repeat the above steps for processing the next workpiece.

[0027] The utility model realizes the fixation of the ceramic core workpiece by adopting the cooperation of the control link 5 to drive the clamping piece 3 and the positioning piece 2.
