During the use process, when adjustment is needed, the turning handle B22 can be pinched and rotated, so that the threaded rod B21 rotates upward inside the slider 6 through the rotating groove B20. When the threaded rod B21 completely rotates out of the inside of the slider 6 through the rotating groove B20 and the bottom end of the turning handle B22 is far from the top of the top plate 8, the fixing plate 9 can be adjusted by pushing and pulling, thus avoiding the situation that like the existing positioning device, due to the lack of a designed adjustment structure, when adjustment is needed after long-term use, tools have to be used for disassembly and then reinstallation.

[0025] Embodiment 2

[0026] Please refer to Figures 1-2 As shown in FIGS. 4 and 5, a clamping groove 23 is formed inside the mounting groove 3. A soft pad 24 is slidably connected inside the clamping groove 23. A sliding plate 25 is fixedly installed on the back of the soft pad 24. A protective cover 26 is fixedly installed on the top of the sliding plate 25, which better protects the fixing bolts. After the fixing bolts firmly fix the base 1 through the mounting groove 3 and the mounting block 2, the protective cover 26 can be pinched and the sliding plate 25 can be aligned with the mounting groove 3 and pressed downward, so that the sliding plate 25 drives the soft pad 24 to slide downward through the mounting groove 3 on the top of the mounting block 2. When the bottom end of the sliding plate 25 contacts the inner wall of the mounting groove 3 and the soft pad 24 slides into the inside of the clamping groove 23, the protective cover 26 can be firmly clamped on the top of the mounting block 2 through the sliding plate 25, thereby preventing the fixing bolts from being corroded and aged due to rainwater after long-term use. The soft pad 24 is slidably connected to the mounting block 2, the sliding plate 25 is slidably connected to the mounting block 2, the sliding plate 25 is slidably connected to the mounting groove 3, and the protective cover 26 is slidably connected to the mounting block 2, which makes it more convenient for the soft pad 24 and the sliding plate 25 to slide and avoids the situation where the soft pad 24 and the sliding plate 25 are stuck by the mounting block 2 during use, resulting in the inability of the soft pad 24 and the sliding plate 25 to continue sliding.

[0027] Working principle: When in use, first place the base 1 in the required position, then use the fixing bolts to firmly fix the base 1 through the mounting block 2 and the mounting groove 3. Then, pinch the protective cover 26 and align the sliding plate 25 with the mounting groove 3 and press it downwards, so that the sliding plate 25 drives the soft pad 24 to slide downwards through the mounting groove 3 at the top of the mounting block 2. When the bottom end of the sliding plate 25 touches the inner wall of the mounting groove 3 and the soft pad 24 slides into the inner part of the clamping groove 23, the protective cover 26 can be firmly clamped at the top of the mounting block 2, thus achieving the effect of protecting the fixing bolts. Then, place the workpiece in the middle of the fixing plate 9 and hold the rotating handle A18 to rotate, so that the threaded rod A13 rotates towards the middle of the fixing plate 9 on the surface of the fixing block 10 through the rotating groove A12. And at this time, the limiting rod 17 fixed on the surface of the clamping plate 14 through the mounting rod 16 can slide through the limiting groove 11 inside the fixing plate 9 and the fixing block 10. When the cushion 15 on the side of the clamping plate 14 touches the workpiece, the workpiece can be firmly clamped in the middle of the fixing plate 9. During the use process, when adjustment is needed, pinch the rotating handle B22 to rotate, so that the threaded rod B21 rotates upwards inside the slider 6 through the rotating groove B20 and rotates upwards at the bottom end of the top plate 8 through the fixing groove 19. When the threaded rod B21 completely rotates out of the inside of the slider 6 through the rotating groove B20 and the bottom end of the rotating handle B22 is far away from the top end of the top plate 8, the fixing plate 9 can be pushed and pulled, so that the slider 6 slides inside the base 1 through the sliding groove 5, and the slider 6 drives the top plate 8 to slide on the top of the base 1 through the support block 7. The threaded rod B21 slides inside the base 1 through the sliding groove 4. When the top plate 8 drives the workpiece to slide to the required position, the rotating handle B22 can be tightened to complete the adjustment.
