Each set of movable rods has a fixed shaft on the side closest to each other. A round rod is rotatably connected inside the fixed shaft. A clamping block is fixed to the end of the round rod away from the fixed shaft. A clamping groove is opened on the side of the clamping block away from the round rod. Multiple sets of return springs are installed at the top of the inner wall of the clamping groove. A pressure plate is fixed to the bottom of the return spring. Two sets of guide rods are fixedly connected to the top of the pressure plate near the return spring. A flexible baffle is slidably connected to the inner wall of the clamping groove. A vertical plate is fixed to one side of the flexible baffle. A set screw rod that abuts against one side of the clamping block is rotatably connected inside the vertical plate. The rotating assembly includes a long rod fixed to one side of the round rod. A ring is slidably connected to the outer curved surface of the long rod. Two sets of spring telescopic rods are fixed to the side of the ring away from the long rod. Pull rings are fixedly connected to the movable ends of the two sets of spring telescopic rods, and a round block is fixed to one end of each spring telescopic rod.
[0006] According to some embodiments of this utility model, a servo motor is installed on one side of the inside of the workbench, and a bidirectional threaded screw is fixed at the output end of the servo motor. The two sets of moving rods are rotatably connected to the bidirectional threaded screw.
[0007] According to some embodiments of the present invention, the top of the workbench is provided with sliding grooves on both sides for the sliding rod to slide.
[0008] According to some embodiments of this utility model, the top ends of the two sets of guide rods penetrate through the upper end of the clamping block, and the guide rods are slidably connected to the clamping block.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0018] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 6 The PCB circuit board fixing fixture shown includes a worktable 100, with fixing components 200 slidably connected to both sides of the top of the worktable 100, and a rotating component 300 provided on one side of the fixing components 200. The fixed assembly 200 includes movable rods 230 slidably connected to both sides of the top of the worktable 100. Each of the two movable rods 230 has a fixed shaft 240 on the side close to each other. A round rod 250 is rotatably connected inside the fixed shaft 240. A clamping block 260 is fixed to the end of the round rod 250 away from the fixed shaft 240. A clamping groove 261 is opened on the side of the clamping block 260 away from the round rod 250. Multiple sets of return springs 270 are installed at the top of the inner wall of the clamping groove 261. A pressure plate 280 is fixed to the bottom of the return spring 270. Two sets of guide rods 290 are fixedly connected to the top of the pressure plate 280 near the return spring 270. A flexible baffle 2910 is slidably connected to the inner wall of the clamping groove 261. A vertical plate 2920 is fixed to one side of the flexible baffle 2910. A top screw 2930 that abuts against one side of the clamping block 260 is rotatably connected inside the vertical plate 2920. The rotating assembly 300 includes a long rod 310 fixed to one side of the round rod 250. A ring 320 is slidably connected to the outer curved wall of the long rod 310. Two sets of spring telescopic rods 330 are fixed to the side of the ring 320 away from the long rod 310. Pull rings 340 are fixedly connected to the movable ends of the two sets of spring telescopic rods 330, and a round block 350 is fixed to one end of the spring telescopic rod 330.
[0019] The operator moves the vertical plate 2920, causing it to move the flexible baffle 2910 within the clamping groove 261 to the desired position. Then, the operator rotates the top screw 2930 to limit the movement of the vertical plate 2920 and the flexible baffle 2910. Adjusting the flexible baffle 2910 allows for better alignment of the circuit board's edges when it is clamped and fixed within the clamping groove 261, preventing damage to the circuit board edges from hard contact with the clamp. The flexible baffle 2910 itself has a certain degree of flexibility, providing cushioning during clamping and reducing pressure damage to the circuit board. When the clamping angle of the circuit board needs adjustment, the operator pulls the pull ring 340, which in turn moves the spring telescopic rod 330 and the circular ring 32. The ring 320 slides on the long rod 310, causing the ring 320 to disengage the limiting block 321 from the limiting groove 322. Then, the ring 320 is rotated, causing the ring 320 to drive the spring telescopic rod 330 and the round block 350 to rotate synchronously. The round block 350 drives the long rod 310 and the round rod 250 to rotate, thereby driving the clamping block 260 and the clamped circuit board to rotate to the required angle. This makes it convenient for the staff to operate the circuit board at different angles, greatly improving the convenience and efficiency of operation and meeting the diverse production needs in the electronics manufacturing field. After the angle adjustment is completed, the staff releases the pull ring 340, and the elastic force of the spring telescopic rod 330 will cause the ring 320 to reset, so that the limiting block 321 is re-engaged into the corresponding limiting groove 322, thereby fixing the rotated angle and ensuring that the circuit board remains stable during operation.
[0020] In this embodiment, a servo motor 210 is installed on one side inside the workbench 100. A bidirectional threaded screw 220 is fixed at the output end of the servo motor 210. Two sets of moving rods 230 are rotatably connected to the bidirectional threaded screw 220. Moving grooves 101 for the moving rods 230 to slide are provided on both sides of the top of the workbench 100. The top ends of two sets of guide rods 290 pass through the upper end of the clamping block 260, and the guide rods 290 are slidably connected to the clamping block 260. A set of horizontal plates 291 is fixed at the top of the two sets of guide rods 290. Slider blocks 2911 are fixed on both sides of the upper and lower ends of the flexible baffle 2910. The inner wall of the clamping groove 261 is provided with a sliding groove 2912 for the slider 2911 to move. Four sets of limiting blocks 321 are fixed on the curved outer wall of the ring 320. A limiting groove 322 that cooperates with the ring 320 and the limiting block 321 is provided on the upper side of one side of the moving rod 230. The round block 350 is fixed to the long rod 310.
[0021] By starting the servo motor 210 to drive the bidirectional threaded screw 220 to rotate, the bidirectional threaded screw 220 drives two sets of moving rods 230 to move in opposite directions or in opposite directions within the moving groove 101. This allows for flexible adjustment according to PCB circuit boards of different sizes, ensuring that the circuit board can be firmly clamped on the worktable 100, thus improving production efficiency. By setting the guide rod 290, the pressure plate 280 can move stably up and down along the trajectory of the guide rod 290 when subjected to the elastic force of the return spring 270, ensuring that the pressure plate 280 applies uniform and stable pressure to the PCB circuit board. At the same time, the flexible baffle 2910 slides in the sliding groove 2912 on the inner wall of the clamping groove 261 via the slider 2911, which can avoid excessive pressure on the circuit board and damage. By setting the limiting groove 322, it can closely cooperate with the limiting block 321 on the ring 320, thereby effectively limiting the movement range of the ring 320 and preventing unnecessary displacement during operation.
[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
