The cabinet barrel with a length of more than one meter by the current common process tooling requires high tooling precision, and the quality of the guide rail and the non-linear impact force of the buffer are also very high, which is not perfect in objective application; 2. In actual application, the non-central push-pull cabinet barrel is often used; 3. The load weight of the cabinet barrel is heavy on the left or right side, and the unbalanced state causes the cabinet barrel to be out of balance and produce inclination during the in-out process; 4. The machining accuracy of the parts of the cabinet barrel is not enough, causing the linear stroke error to be enlarged; 5. Because the assembly of the parts of the cabinet barrel is too high, the hardness of the application material is too high, and under this condition, the stress point and the friction coefficient of the structure are too high, and the compression angle stop phenomenon occurs when the cabinet barrel is pushed and pulled; 6.
