[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Referring to Figures (1-3), a PCB board processing positioning component includes a positioning disk 1. The top of the positioning disk 1 has several mounting holes 11. A support block 2 is provided on the top of the positioning disk 1. A limit plate 3 is slidably provided on the top of the support block 2. A mounting block 23 is provided at the bottom of the support block 2. The mounting block 23 is slidably connected to the mounting holes 11. An annular groove 13 is provided at the bottom of the positioning disk 1 and around the mounting holes 11. A spring piece 12 is provided in the groove 13. One end of the spring piece 12 is connected to the inner wall of the groove 13, and the other end is bent and inserted into the mounting hole 11 to contact the outer wall of the mounting block 23. A knob 14 is screwed onto the groove 13.

[0015] The knob 14 has a slot, the top of which fits against the spring piece 12. The inner walls of the slot and the groove 13 are threaded. The support block 2 has a sliding groove 21 at its top. The bottom of the limiting plate 3 is slidably connected to the sliding groove 21. Adjustment grooves 22 are formed on both sides of the sliding groove 21. A sliding post 31 is provided on the outer side of the limiting plate 3, passing through and slidably connecting to the adjustment groove 22. One end of the sliding post 31 is connected to the limiting plate 3, and the other end has threads on its outer wall and is screwed with a compression nut 32.

[0016] When using this device, insert the mounting block 23 at the bottom of the support block 2 into the mounting hole 11, tighten the knob 14 to move the knob 14 downward, push the spring piece 12 to squeeze the mounting block 23 in the mounting hole 11, restrict the movement of the mounting block 23 in the mounting hole 11, push the limiting plate 3 on the top slide groove 21 of the support block 2 to move, and then rotate the compression nut 32 to squeeze the side wall of the support block 2, restricting the movement of the limiting plate 3. Install multiple support plates 2 on the positioning plate 1 to form an area for placing and restricting the position of the PCB board.
