[0002] Furniture refers to the essential equipment and facilities for humans to maintain normal life, engage in production practice and carry out social activities. Furniture has also been continuously developing and innovating with the times. Today, there are many categories, different materials, complete varieties and different uses. It is an important foundation for establishing a working and living space.

[0003] In the panel furniture industry, multi-blade saws are used for cutting. The spindle of the multi-blade saw is generally connected to the machine. The installation of the saw blade and the thickness block is carried out on the machine. The workpiece after cutting needs to be planed on four sides or fixed in width before use, so the precision requirement is generally not high. However, the existing sawing spindle has the following disadvantages: 1. It is inconvenient to debug and install. The spindle and the device are connected to each other. When replacing the product, all the saw blades and the thickness block need to be removed and then installed with a new one; 2. The precision is not high. Since all operations are completed on the machine, the use environment of the thickness block and the saw blade is rough and the degree of wear is different.

It is flexible to adjust the machine and can adjust multiple cutting schemes at the same time by using multiple sets of spindles. It has high precision and can grind saw blades at the same time when batches are used, avoiding different degrees of saw blade wear caused by different grinding times, thereby affecting the quality of cutting. It has better protection for the spindle and reduces the risk of spindle deformation. Summary of the invention
