The threaded rod 22 rotates inside the fixed block 20 through the fixing groove 21, and the threaded rod 22 rotates inside the base 14 through the rotating groove 18, which makes it more convenient for the threaded rod 22 to rotate, preventing the threaded rod 22 from being stuck by the fixed block 20 or the base 14 during use, which makes it impossible for the threaded rod 22 to continue rotating.

[0026] Example 2

[0027] See also Figure 1-3 6. A sliding groove 24 is provided inside the fixture 1, and a limiting groove 25 is provided inside the sliding groove 24. The limiting groove 25 is internally connected to a limiting plate 26 for sliding movement. A collecting box 27 is installed in the middle of the limiting plate 26, and a soft pad 28 is installed on the surface of the limiting plate 26, which is more convenient for collecting debris. During use, the debris generated by processing will fall into the interior of the collecting box 27 through the groove 3, and then the collecting box 27 is pinched and pulled out through the sliding groove 24, and the limiting plate 26 slides out of the interior of the fixture 1 through the limiting groove 25, and then the debris can be collected. The chips are cleaned up to prevent the poor use effect caused by the inability to collect them during use. The limiting grooves 25 are symmetrically distributed at the front and rear ends of the sliding plate. The limiting plate 26 is slidingly connected to the clamp 1, and the collection box 27 slides inside the clamp 1 through the sliding groove 24. The soft pad 28 is slidingly connected to the clamp 1, which makes it more convenient for the limiting plate 26 and the collection box 27 to slide, and avoids the limiting plate 26 and the collection box 27 being stuck by the clamp 1 during use, which makes the limiting plate 26 and the collection box 27 unable to continue sliding.

[0028] Working principle: Before use, first place the base 14 in the required position, and fix the base 14 firmly through the mounting plate 16 and the mounting slot 17, then use the card block 13 to correspond to the upper card slot 15 and push it forward so that the card block 13 can slide completely into the interior of the base 14 through the card slot 15, then pinch the rotating block 23 through the fixed slot 21, through the fixed block 20 and correspond to the upper rotating slot 18, and then rotate it so that the rotating block 23 drives the threaded rod 22 through the rotating slot 18 to rotate like the interior of the base 14. When the threaded rod 22 is completely rotated into the interior of the base 14 through the soft pad 28, it is OK. At this time, the threaded rod 22 can use the fixing plate 19 to firmly clamp the bottom plate 12 on the top of the base 14, and then place the workpiece on the top of the fixture 1, and hold the handle 6 to rotate it. , so that the reciprocating screw rod 5 rotates inside the clamp 1 through the rotating groove 4, and the reciprocating screw rod 5 drives the sliding block 7 to rotate through the threaded groove 8. At this time, the connecting block 9 slides on the top of the clamp 1 through the sliding groove 2, and drives the clamping plate 10 to slide. When the anti-slip pad 11 contacts the workpiece, it can be firmly fixed. During the processing, the debris generated by the processing will fall into the interior of the collection box 27 through the groove 3. After use, pinch the collection box 27 and pull it to the left, so that the limit plate 26 slides to the left inside the clamp 1 through the limit groove 25, and the collection box 27 slides to the left inside the clamp 1 through the sliding groove 24. When the limit plate 26 drives the soft pad 28 and the collection box 27 to completely slide out of the interior of the clamp 1, the debris can be cleaned up.
