High-precision saw bench with protection function

A high-precision saw table with a protection function comprises a machining table, a cutting structure and a positioning structure, and relates to the technical field of wood board machining, a vertical plate is arranged at the rear upper end of the machining table, the cutting structure is arranged on the front side of the vertical plate, and movable grooves are formed in the left side and the right side of the interior of the machining table; a second threaded rod and a second auxiliary rod are arranged in the movable groove, and the second auxiliary rod is located on the lower side of the second threaded rod. The applicability of the device is improved by adjusting the positions of two baffles, so that the device can position wood boards with different sizes within a certain range; by adjusting the position of the pressing plate, the device can position wood boards with different thicknesses within a certain range, and edge warping of the wood boards in the machining process is prevented; the stability of
