[0014] 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.

[0015] Please see Figures 1-4As shown, this embodiment provides a fixing device for the production and processing of plastic products, including a base 1, a support column 2 and a fixing hoop 3; the support column 2 is fixedly installed on the base 1, and its vertical structure provides a support carrier for the height adjustment of the fixing hoop 3, and the position of the fixing hoop 3 on the support column 2 can be adjusted according to the processing height requirements of the plastic products.

[0016] The fixing hoop 3 is fitted onto the support column 2. Its core function is to connect the support column 2 with the subsequent fixing components, so as to achieve flexible adjustment of the fixing position. The fixing hoop 3 has a horizontally penetrating mounting hole 303, which is used to install the connecting rod 5 through, providing a channel for adjusting the horizontal position and angle of the connecting rod 5. The connecting rod 5 can be pushed and pulled horizontally along the mounting hole 303 to adjust the extension length, and can also be finely adjusted around the axis of the mounting hole 303, thereby driving the fixing seat 6 to adapt to the fixing needs of plastic products of different sizes and processing orientations. One end of the connecting rod 5 is fixedly connected to a U-shaped fixing seat 6. The structural design of the U-shaped fixing seat 6 can adapt to the shape of most plastic products, making it easy to place the plastic products inside the seat for positioning, while providing an installation base for the clamping plate 7. The fixing seat 6 is symmetrically equipped with clamping plates 7. One clamping plate 7 is fixedly connected to the fixing seat 6, serving as a fixed end to limit one side of the plastic product. The other clamping plate 7 is rotatably connected to a screw 8 on one side. The screw 8 passes through the vertical section of the fixing seat 6 and is threadedly connected to that vertical section of the fixing seat 6. By rotating the screw 8, the movable clamping plate 7 can be pushed to move horizontally, realizing the clamping and loosening of plastic products of different widths, ensuring that the plastic products do not shift during processing.

[0017] In summary, the improvement of this embodiment lies in the following: by adjusting the height and angle of the fixing hoop 3 on the support column 2, adjusting the horizontal position of the connecting rod 5 in the mounting hole 303, and adjusting the clamping width of the screw 8 pushing the clamping plate 7, multi-dimensional adjustments of the fixed position, angle, height, and clamping size are achieved. This allows it to be adapted to plastic products of different sizes and structures, and its adaptability to irregularly shaped plastic products or multi-directional processing scenarios is significantly improved, solving the problem of poor versatility of existing devices.

[0018] Based on the above, other structures also need to be disclosed in detail, such as: Furthermore, to facilitate the operator's rotation of the screw 8, a plum blossom-shaped rotating handle 9 is fixedly provided at the end of the screw 8 away from the clamping plate 7. The plum blossom-shaped rotating handle 9 can increase the friction between the hand and the handle body, prevent slippage during rotation, and at the same time conform to the ergonomic design, reduce the operator's hand fatigue, and ensure that a stable rotational force can be applied to push the screw 8 to move.

[0019] To enable quick assembly and disassembly, height fixation, and angle fine-tuning of the fixing hoop 3 on the support column 2, the fixing hoop 3 consists of a first arc plate 301 and a second arc plate 302. One end of the first arc plate 301 and the second arc plate 302 are hinged together, and a locking component 4 is provided between the other ends. The hinged connection structure allows the fixing hoop 3 to open and close around the hinge point, making it convenient to put on or remove the fixing hoop 3 from the support column 2. The locking component 4 is used to lock the free ends of the first arc plate 301 and the second arc plate 302 after the fixing hoop 3 is adjusted to the target height and angle. By moving the lever 404 to drive the main shaft 401 to rotate, the eccentric connecting shaft 402 will pull the pull rod 403 to extend and retract along the connecting hole 307 of the second arc plate 302, thereby achieving the clamping and loosening of the first and second arc plates 302, ensuring that the fixing hoop 3 is stably fixed on the support column 2, and preventing the fixing hoop 3 from sliding or rotating during processing. To further enhance the connection stability between the connecting rod 5 and the fixing clamp 3, and between the fixing clamp 3 and the support column 2, and to achieve the linkage effect of "one adjustment and double fixation", the inner sidewall of the first arc plate 301 is provided with a sliding groove 304 communicating with the mounting hole 303. The sliding groove 304 slides through a limiting block 305. One end of the limiting block 305 extends into the interior of the mounting hole 303 and is provided with a first arc groove 3051 that matches the shape of the connecting rod 5. The first arc groove 3051 can fit tightly against the outer wall of the connecting rod 5, limiting the shaking and angular displacement of the connecting rod 5 within the mounting hole 303. The other end of the limiting block 305 extends between the first arc plate 301 and the support column 2. Furthermore, a second arc groove 3052 adapted to the shape of the support column 2 is provided. The second arc groove 3052 can fit against the outer wall of the support column 2. When the locking component 4 is locked and the first arc plate 301 and the second arc plate 302 clamp the support column 2, the support column 2 will squeeze the limiting block 305 to slide towards the mounting hole 303, so that the first arc groove 3051 clamps the connecting rod 5 simultaneously, realizing the linkage effect of "the connecting rod 5 is also fixed at the same time as the fixing hoop 3 is fixed". Conversely, when the locking component 4 is unlocked, the squeezing force of the support column 2 on the limiting block 305 disappears, and the limiting block 305 can slide with the movement of the connecting rod 5, releasing the fixation of the connecting rod 5 and ensuring a smooth adjustment process.

[0020] Regarding the specific structure of the locking component 4, it includes a main shaft 401, a connecting shaft 402, and a pull rod 403. A groove 306 is provided on the second arc plate 302, providing space for the installation of the locking component 4 and preventing exposed components from affecting operation. A connecting hole 307 is horizontally provided on the second arc plate 302, which is used to slide through the pull rod 403, providing guidance for its horizontal movement. One end of the pull rod 403 is fixedly connected to the first arc plate 301, and the other end is fixedly connected to the connecting shaft 402. The pull rod 403 serves as the connection medium between the first arc plate 301 and the connecting shaft 402, and can extend and retract with the opening and closing of the first arc plate 301 and the second arc plate 302. The connecting shaft 402 is eccentrically mounted on the main shaft 401, and the connecting shaft 402 is rotatably connected to the main shaft 401. The eccentrically mounted connecting shaft 402 is the core structure for realizing the extension and retraction of the pull rod 403. When the main shaft 401 is rotated, the eccentric connecting shaft 402 will make a circular motion around the center of the main shaft 401, thereby pulling the pull rod 403 to move along the direction of the connecting hole 307, realizing the tightening and loosening of the first and second arc plates 302. A lever 404 is fixedly connected to the main shaft 401. The lever 404 can amplify the force applied by the operator. Just by gently moving the lever 404, the main shaft 401 can be rotated, quickly completing the locking and unlocking operation of the locking component 4, and improving the efficiency of adjusting the height and angle of the fixing hoop 3.

[0021] In summary, the workflow of this solution is as follows: According to the size and specifications of the plastic product to be processed and the actual processing requirements, firstly, the locking component 4 of the fixing hoop 3 is unlocked. Then, the lever 404 on the main shaft 401 is moved, causing the main shaft 401 to drive the eccentric connecting shaft 402 to rotate synchronously. During rotation, the eccentric connecting shaft 402 pulls the pull rod 403 outward along the connecting hole 307 of the second arc plate 302, thereby causing the first arc plate 301 and the second arc plate 302 to expand outward around the hinge point, causing the inner wall of the fixing hoop 3 to disengage from the outer wall of the support column 2, thus releasing the fixing hoop 3. The height of the support column 2 is fixed. At this time, the squeezing effect of the support column 2 on the limiting block 305 disappears, and the limiting block 305 no longer clamps and fixes the connecting rod 5. The operator can adjust three parameters simultaneously according to the processing requirements: First, move the fixing hoop 3 up and down to adjust it to the target height on the support column 2; second, push and pull the connecting rod 5 along the mounting hole 303 of the fixing hoop 3 to adjust its length extending out of the mounting hole 303; third, fine-tune the angle of the connecting rod 5 to drive the U-shaped fixing seat 6 to be adjusted to the angle suitable for placing the plastic product. After all parameters are adjusted, the lever 404 is reversed to relock the locking assembly 4. The main shaft 401 drives the eccentric connecting shaft 402 to rotate in the opposite direction, pulling the lever 403 inward. The first arc plate 301 and the second arc plate 302 re-clamp the support column 2, and the height and angle of the fixing hoop 3 are fixed. At the same time, the support column 2 squeezes the limiting block 305, and the first arc groove 3051 of the limiting block 305 fits tightly with the outer wall of the connecting rod 5. The position and angle of the connecting rod 5 are fixed synchronously, completing the pre-adjustment operation.

[0022] The plum blossom-shaped rotating handle 9 at the end of the rotating screw 8 drives the screw 8 to rotate along the internal thread of the vertical section of the fixed base 6 through rotational force, thereby pushing the movable clamping plate 7 to move horizontally away from the fixed clamping plate 7, forming a gap for the plastic product to be placed. The plastic product to be processed is then placed smoothly between the two clamping plates 7 of the U-shaped fixed base 6, ensuring that the part of the product to be processed is fully exposed and that the product's placement is compatible with the working path of the processing tool. Then, the plum blossom-shaped rotating handle 9 is rotated in the opposite direction, and the screw 8 drives the movable clamping plate 7 to move towards the fixed clamping plate 7 until the inner walls of the two clamping plates 7 are tightly fitted with the outer wall of the plastic product. Finally, the plastic product is gently pushed by hand to confirm that there is no shaking or displacement, completing the clamping and fixing operation of the plastic product, which can then proceed to the subsequent processing steps.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
