[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] refer to Figure 1-2 , a protective structure of a sawing machine, comprising a sleeve 1 and a detachable support 6;

[0024] Inner rods 2 are telescopically installed on both sides of the sleeve 1, and a support arm 3 is fixedly installed on the other end of the inner rod 2;

[0025] A clamp 4 for clamping and fixing with both sides of the sawing machine is installed on the inner side of the lower side of the support arm 3;

[0026] Secondly, first fastening bolts 5 are rotatably inserted into both sides of the top of the sleeve 1. After the first fastening bolts 5 penetrate through the sleeve 1, they can be pressed against the outer wall of the top of the inner rod 2, thereby achieving the fixing of the inner rod 2 in the sleeve 1;

[0027] The detachable support 6 is clamped and installed on the top of the sleeve 1, and a telescopic rod 7 is fixedly installed on the top of the detachable support 6, and a bracket 9 is fixedly installed on the top of the telescopic rod 7. A movable plate 10 is fixedly installed on the bottom of the other end of the bracket 9, and protective plates 11 are symmetrically installed on both sides of the bottom of the movable plate 10. The two sets of protective plates 11 are movable and penetrate the detachable support 6, and a spring 8 is sleeved on the outside of the telescopic rod 7;

[0028] Among them, guide wheels 12 are movably installed on both sides of the bottom of the protective plate 11 to facilitate the plate to enter the bottom of the protective plate 11;

[0029] Secondly, a second fastening bolt 13 is rotatably inserted into the rear side of the detachable support 6. The second fastening bolt 13 penetrates the detachable support 6 and abuts against the outer wall of the rear side of the sleeve 1, thereby achieving the fixing work when the detachable support 6 is installed on the sleeve 1;

[0030] In this embodiment, the spacing between the two side arms 3 can be adjusted by extending the inner rod 2 in the sleeve 1, thereby facilitating the fixed installation of the structure on sawing machines of different sizes and improving adaptability. The free disassembly and assembly of the detachable support 6 on the sleeve 1 can facilitate the free adjustment of its installation position on the sleeve 1, ensuring that the two groups of protective plates 11 can be placed on both sides of the saw blade respectively, and is suitable for installation and use on sawing machines with different saw blade positions. When the plate is on the sawing machine and pushed toward the saw blade, it can first be inserted under the two groups of protective plates 11. At this time, the two groups of protective plates 11 can be pushed upward, and the bracket 9 and the telescopic rod 7 will move upward, and pull the spring 8. When the plate is cut, the tension of the spring 8 can drive the bracket 9 and the protective plate 11 to move downward, so that the two groups of protective plates 11 can always be placed on both sides of the saw blade, thereby effectively preventing accidental contact with the saw blade.

[0031] Working principle: First, the spacing of the two side arms 3 can be adjusted by telescopically adjusting the inner rod 2 in the sleeve 1. After adjusting the spacing, the clamp 4 can be used to clamp and fix it on both sides of the sawing machine, so as to complete the installation of the sleeve 1 above the sawing machine, and then the first fastening bolt 5 can be rotated to complete the fixing of the inner rod 2 in the sleeve 1, and then the detachable support 6 can be placed on the sleeve 1, and its position above the sleeve 1 can be adjusted to ensure that the two groups of protective plates 11 can be placed on both sides of the saw blade respectively, and then the second fastening bolt 13 can be rotated to complete the fixing of the detachable support 6 on the sleeve 1. At this time, the two groups of protective plates 11 can be located on both sides of the saw blade for protection to prevent damage from side contact with the saw blade. When cutting is required, the plate can be directly pushed under the two groups of protective plates 11. At this time, the protective plates 11 can move upward after being squeezed, and under the pulling force of the spring 8, the bracket 9, the movable plate 10 and the protective plate 11 can simultaneously maintain downward pressure, thereby ensuring that the two groups of protective plates 11 can always be close to the surface of the plate, ensuring that the protective effect can still be maintained during the cutting process.
