[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5As shown, this utility model provides a technical solution: a linear stapler that is easy to disassemble, including a stapler body 1, an adjusting column 2 fixedly connected to one end of the stapler body 1, a rotating column 3 rotatably connected inside the adjusting column 2, a cutting component 4 disposed inside the rotating column 3, arc blocks 5 fixedly connected to both ends inside the adjusting column 2, adjusting grooves 6 opened at both ends of the rotating column 3, a push block 7 slidably connected inside the adjusting groove 6, an insertion rod 8 fixedly connected to the side of the push block 7 away from the arc block 5, and slots 9 opened at both ends of the cutting component 4. By rotating the rotating column 3, the operator moves the push block 7 and the insertion rod 8, gradually canceling the contact between the push block 7 and the arc block 5. At the same time, under the action of the rebound force of the storage spring 10, the push block 7 is pushed, and the insertion rod 8 is released from the limit between itself and the slot 9, so that the limit of the cutting component 4 is also released, making it convenient for the operator to disassemble the cutting component 4.

[0022] Reference Figure 4 As shown in this embodiment: a storage spring 10 is fixedly connected to the side of the push block 7 near the insertion rod 8, and the side of the storage spring 10 away from the push block 7 is fixedly connected to the inside of the adjustment groove 6. When the operator pushes the push block 7 to push the insertion rod 8, the push block 7 compresses the storage spring 10 to store force, and drives the insertion rod 8 to insert into the slot 9. When the operator releases the restriction of the insertion rod 8, under the action of the rebound force of the storage spring 10, the storage spring 10 can quickly rebound and push the insertion rod 8 to move away from the push block 7, thereby realizing the rapid separation between the insertion rod 8 and the slot 9.

[0023] Reference Figure 2 and Figure 4 As shown in this embodiment: the size of the insertion rod 8 is adapted to the size of the slot 9, and the surface of the insertion rod 8 is inserted into the interior of the slot 9. By adapting the size of the insertion rod 8 to the size of the slot 9, the insertion rod 8 can be stably inserted into the slot 9, thereby enhancing the stability of the entire device. During the assembly process, the insertion and engagement between the insertion rod 8 and the slot 9 can ensure the precise positioning between the components and avoid shaking or misalignment during use.

[0024] Reference Figure 4 As shown in this embodiment: sliding grooves 11 are provided on both sides of the inner side of the adjusting groove 6, and sliders 12 are fixedly connected to both sides of the push block 7. The surface of the slider 12 is slidably connected to the inside of the sliding groove 11. When the operator moves the push block 7, the push block 7 drives the slider 12 to slide inside the sliding groove 11. Through the above settings, the movement of the push block 7 is more stable, and the sliding of the slider 12 inside the sliding groove 11 plays a limiting role, avoiding the phenomenon of the push block 7 deviating when moving, ensuring the accuracy of the push block 7 when moving, thereby improving the practicality of the device.

[0025] ReferenceFigure 5 As shown in this embodiment: the inner wall of the adjusting column 2 is provided with two annular grooves 13, and the outer diameter of the rotating column 3 is fixedly connected with two annular blocks 14. The surface of the annular blocks 14 is slidably connected to the inside of the annular grooves 13. When the operator rotates the rotating column 3, the rotating column 3 drives the annular blocks 14 to slide inside the annular grooves 13. Through the above setting, the stability of the rotating column 3 during rotation can be increased, and the shaking of the rotating column 3 during rotation can be avoided, further improving the stability of the overall structure.

[0026] Reference Figure 5 As shown in this embodiment: a rubber pad 15 is installed inside the adjusting column 2 on the side close to the cutting component 4. By installing the rubber pad 15 inside the adjusting column 2 on the side close to the cutting component 4, the friction between the adjusting column 2 and the cutting component 4 is increased, making the installation of the cutting component 4 inside the adjusting column 2 more stable and avoiding the phenomenon of loosening of the cutting component 4 during use, thereby ensuring the stability and service life of the device.

[0027] Reference Figure 5 As shown in this embodiment: a return spring 16 is fixedly connected to the side of the adjusting column 2 away from the annular block 14. The side of the return spring 16 away from the inside of the adjusting column 2 is fixedly connected to the annular block 14. When the operator rotates the rotating column 3, the rotating column 3 drives the annular block 14 to twist the return spring 16 to store force, and drives the limit between the push block 7 and the arc block 5 to be released. At the same time, under the action of the rebound force of the stored spring 10, the push block 7 is pushed to drive the insertion rod 8 to release the limit between it and the slot 9. When the operator releases the rotating column 3, under the action of the rebound force of the return spring 16, the annular block 14 quickly returns to its original position, and drives the push block 7 and the arc block 5 to re-establish the limit. At the same time, the insertion rod 8 also re-establishes the limit between it and the slot 9 under the action of the rebound force of the return spring 16. Through the above settings, the device is more convenient to disassemble. The disassembly action can be completed simply by rotating the rotating column 3 without the need for other tools, which greatly improves the disassembly efficiency and reduces the difficulty of operation, making it more convenient for medical staff to use.

[0028] Working principle: By rotating the rotating column 3, the operator moves the push block 7 and the insertion rod 8, gradually releasing the contact between the push block 7 and the arc block 5. Simultaneously, the rebound force of the storage spring 10 pushes the push block 7, causing the insertion rod 8 to release its restriction from the slot 9, thus releasing the restriction on the cutting component 4 and facilitating disassembly of the cutting component 4. When the operator pushes the insertion rod 8 with the push block 7, the push block 7 compresses the storage spring 10, storing energy and causing the insertion rod 8 to insert into the slot 9. When the operator releases the restriction on the insertion rod 8, the rebound force of the storage spring 10 quickly returns, pushing the insertion rod 8 away from the push block 7, thereby achieving... The quick separation between the insertion rod 8 and the slot 9 is achieved through a design where the dimensions of the insertion rod 8 and the slot 9 are matched, allowing the insertion rod 8 to be stably inserted into the slot 9. This enhances the overall stability of the device. During assembly, the insertion and engagement between the insertion rod 8 and the slot 9 ensures precise positioning of the components, preventing shaking or misalignment during use. When the push block 7 is moved, it drives the slider 12 to slide within the slide groove 11. This design makes the movement of the push block 7 more stable, and the slider 12's movement within the slide groove 11 acts as a limit, preventing the push block 7 from shifting during movement and ensuring its accuracy, thereby improving stability. The device is practical because when the operator rotates the rotating column 3, the rotating column 3 drives the annular block 14 to slide inside the annular groove 13. This design increases the stability of the rotating column 3 during rotation, preventing it from wobbling and further improving the overall structural stability. The rubber pad 15 installed on the side of the adjusting column 2 near the cutting component 4 increases the friction between the adjusting column 2 and the cutting component 4, making the installation of the cutting component 4 more secure inside the adjusting column 2 and preventing it from loosening during use. This ensures the stability and service life of the device. When the operator rotates the rotating column 3, the rotating column 3 drives the annular block 14 to twist back... The force spring 16 stores energy and causes the limit between the push block 7 and the arc block 5 to be released. At the same time, under the action of the rebound force of the stored spring 10, the push block 7 is pushed to release the limit between the insertion rod 8 and the slot 9. When the operator releases the rotating column 3, under the action of the rebound force of the return spring 16, the annular block 14 quickly resets and causes the push block 7 and the arc block 5 to re-establish the limit. At the same time, the insertion rod 8 also re-establishes the limit with the slot 9 under the action of the rebound force of the return spring 16. Through the above settings, the device is more convenient to disassemble. The disassembly action can be completed simply by rotating the rotating column 3 without the need for other tools, which greatly improves the disassembly efficiency and reduces the difficulty of operation, making it more convenient for medical staff to use.
