[0022] A pair of connecting seats 2 are slidably installed, and the sliding of the pair of connecting seats 2 can drive the movement of a pair of fixed plates 3. A sliding opening 17 is provided, and a limiting ring 16 can be set in the sliding opening 17. With the limiting ring 16 and a sliding groove 5, when the clamping head 4 is installed, the sliding rod 6 on the clamping head 4 can slide in the sliding groove 5, so as to facilitate the installation and removal of the clamping head 4. With the clamping head 4 provided, the pair of clamping heads 4 can move relative to each other and work together to clamp and fix the parts. With the positioning component provided, several sliding rods 6 can be fixed, so that the clamping head 4 can be fixed on the fixed plate 3, so as to facilitate the clamping head 4 to clamp and fix the parts. This structure can facilitate the quick installation and removal of the clamping head 4 by the workers, and facilitates the replacement and maintenance of clamping heads 4 of different specifications and shapes according to processing needs.

[0023] Furthermore, the positioning component includes elastic clips 7, several pairs of elastic clips 7 are disposed on one side of several sliding grooves 5, and through holes 11 are provided on both sides of the limiting ring 16 located at several pairs of elastic clips 7.

[0024] When the clamping head 4 is installed, the elastic clamping piece 7 is installed. When the several sliding rods 6 slide in the sliding groove 5 to the elastic clamping piece 7, the clamping head 4 squeezes and moves one end of the elastic clamping piece 7. Through the through hole 11, one end of the elastic clamping piece 7 extends out through the through hole 11, so that the clamping head 4 can enter one end of the sliding groove 5 near the side of the elastic clamping piece 7. At this time, the sliding rod 6 can be initially positioned.

[0025] Furthermore, a positioning plate 9 is detached and installed on the other side of the fixing plate 3. The positioning plate 9 is provided with several positioning rods 8, which are inserted into several sliding rods 6.

[0033] The working principle and usage process of this utility model are as follows: During use, the part is placed between a pair of clamping heads 4. The bidirectional threaded rod 10 is rotated to move a pair of sliders 18, which in turn moves a pair of connecting seats 2, thereby moving a pair of fixing plates 3 and the clamping heads 4 to stabilize the part for processing. When the clamping heads 4 need to be replaced or repaired, the positioning plate 9 is removed, and the clamping heads 4 are rotated to remove them for repair or replacement. When reinstalling or installing a new clamping head 4, the sliding rod 6 on the clamping head 4 is inserted into the corresponding sliding groove 5. The clamping head 4 is rotated, causing the sliding rod 6 to press against the elastic clamping piece 7, so that one end of the elastic clamping piece 7 extends out of the through hole 11, allowing the sliding rod 6 to enter one end of the sliding groove 5 where the elastic clamping piece 7 is located, thus initially positioning the sliding rod 6. Then, the positioning rod 8 is inserted into the sliding rod 6 to install the positioning plate 9 onto the fixing plate 3, thus completing the installation of the clamping head 4.
