A torsion spring 8 is connected, and both ends of the torsion spring 8 are fixedly connected to the two opening and closing covers 7 respectively. A first steel wire rope 9 is fixedly connected to the side of the opening and closing covers 7 away from each other. The first steel wire rope 9 is respectively connected to the outer protective shell 3 and the inner protective shell 4. The first steel wire rope 9 runs through the outer protective shell 3. An end of the first steel wire rope 9 away from the closing cover 7 is fixedly connected to the second steel wire rope 10. An end of the second steel wire rope 10 away from the first steel wire rope 9 is fixedly connected to the base 1. A cutting blade 11 is arranged inside the inner protective shell 4. A servo motor 12 is fixedly connected to one side of the rocker arm 2. The servo motor 12 is transmission-connected to the cutting blade 11. A handle 13 is arranged on the side of the rocker arm 2 close to the servo motor 12.

[0022] In the specific implementation process, it is worth pointing out that the main structure of the cutting machine is composed of the cooperation between the base 1, the rocker arm 2, the outer protective shell 3, the cutting blade 11, the servo motor 12, the handle 13 and the connecting seat 23. The rocker arm 2 and the connecting seat 23 are provided with a spring structure. By pressing the handle 13 downward, the rocker arm 2 drives the cutting blade 11 to move downward for cutting. After the pressure on the handle 13 stops, the rocker arm 2 rotates upward and resets under the action of the spring structure. Through the cooperation between the outer protective shell 3, the inner protective shell 4 and the shaft sleeve 5, the inner protective shell 4 is fixed to the outer protective shell 3 through the shaft sleeve 5, so that A cavity is formed between the outer protective shell 3 and the inner protective shell 4. Through the cooperation among the outer protective shell 3, the inner protective shell 4, the shaft sleeve 5, the connecting ring 6 and the opening and closing cover 7, and through the connection between the shaft sleeve 5 and the connecting ring 6, the opening and closing cover 7 can be rotated and opened and closed in the cavity formed between the outer protective shell 3 and the inner protective shell 4. Through the cooperation among the outer protective shell 3, the inner protective shell 4, the shaft sleeve 5, the connecting ring 6, the opening and closing cover 7 and the torsion spring 8, the torsion spring 8 surrounds the shaft sleeve 5 to give the two opening and closing covers 7 an elastic force that approaches each other, so that the two opening and closing covers 7 remain in a closed state, and the side of the cutting blade 11 away from the outer protective shell 3 is covered. The base 1, the rocker arm 2, the outer protective shell 3, the inner protective shell 4, the shaft sleeve 5, the connecting ring 6, the opening and closing cover 7, the torsion spring 8, the first steel wire rope 9, the second steel wire rope 10, the cutting blade 11, the servo motor 12, the handle 13 and the connecting seat 23 cooperate with each other. When the rocker arm 2 is not rotating, the opening and closing cover 7 is kept in a closed state under the action of the torsion spring 8, and the side of the cutting blade 11 away from the outer protective shell 3 is covered. When the cutting operation is required, the rocker arm 2 is pressed downward, and the second steel wire rope 10 and the first steel wire rope 9 pull the two opening and closing covers 7, so that the opening and closing covers 7 are formed toward the outer protective shell 3 and the inner protective shell 4. The rocker arm 2 rotates in the cavity, gradually releasing the covering of the cutting blade 11, and when the rocker arm 2 rotates upward, the opening and closing cover 7 is automatically reset under the action of the torsion spring 8, and the cutting blade 11 is covered again. During the up and down rotation of the rocker arm 2, the opening and closing cover 7 can be opened and closed accordingly, so that the cutting blade is covered more, thereby improving the protection effect of the cutting machine. When the cutting blade is broken, the probability of intercepting the flying fragments can be increased through the opening and closing cover 7, thereby reducing the probability of the flying cutting blade causing harm to the operator. The specific model of the servo motor 12 is not limited, and it can meet the use requirements;

[0023] Furthermore, a limiting tube 14 is provided on the side of the outer wall of the rocker arm 2 away from the cutting blade 11, and the limiting tube 14 is used to guide and limit the first steel wire rope 9 and the second steel wire rope 10, and the limiting tube 14 is respectively connected with the first steel wire rope 9 and the second steel wire rope 10, and a first guide rod 15 is provided on the outer wall of the rocker arm 2 below the limiting tube 14, and a second guide rod 16 is provided on the side of the bottom of the rocker arm 2 close to the second steel wire rope 10, and the first guide rod 15 and the second guide rod 16 are both connected with the second steel wire rope 10;

[0024] In the specific implementation process, it is worth pointing out that the limiting tube 14 is used to guide and limit the first steel wire rope 9 and the second steel wire rope 10, and the first guide rod 15 and the second guide rod 16 are both used to guide and limit the first steel wire rope 9. Through the cooperation among the rocker arm 2, the first steel wire rope 9, the second steel wire rope 10, the limiting tube 14, the first guide rod 15 and the second guide rod 16, the first steel wire rope 9 and the second steel wire rope 10 are guided and limited during the traction and rebound process, ensuring that the two opening and closing covers can be opened and closed stably. At the same time, the limiting tube 14 can cover and protect the first steel wire rope 9 and the second steel wire rope 10, reduce the length of the second steel wire rope 10 exposed to the outside, and improve the service life of the first steel wire rope 9 and the second steel wire rope 10;

[0025] Furthermore, a clamping assembly 17 is installed on one side of the top of the base 1 below the cutting blade 11, and a vertical plate 18 is fixedly connected to the other side of the top of the base 1 below the cutting blade 11 at an equal distance, and a protective cover 19 is rotatably connected to the top of the vertical plate 18;

[0026] In the specific implementation process, it is worth pointing out that the clamping assembly 17 is used to fix the cut material to ensure stable and accurate cutting. Through the cooperation between the base 1, the vertical plate 18 and the protective cover 19, a rotatable protective cover 19 is provided on the other side of the clamping assembly 17 to limit the cut part of the material to prevent the cut material from splashing after separation, thereby improving the safety of the cutting machine when in use;

[0027] Furthermore, a lifting plate 21 is provided on one side of the protective cover 19 away from the vertical plate 18, and a limiting block 20 is provided on the outer wall of the base 1 below the lifting plate 21, and the lifting plate 21 is cooperatively connected with the limiting block 20;

[0028] In the specific implementation process, it is worth pointing out that the protection cover 19 is limited by the cooperation between the base 1, the protection cover 19, the limit block 20 and the lifting plate 21, and the protection cover 19 is convenient to open and close, thereby improving the convenience of the protection cover 19 when in use;

[0029] Furthermore, buffer pads 22 are provided on both sides of the bottom of the base 1, and the buffer pads 22 are used to improve the stability of the cutting machine and reduce the vibration generated during cutting;

[0030] In the specific implementation process, it is worth pointing out that the buffer pad 22 is used to improve the stability of the cutting machine, reduce the vibration generated during cutting, enable the cutting blade to operate stably, and improve the safety factor of the cutting machine;

[0031] Specifically, when the protective device of the cutting machine is used, the cutting material is fixed by the clamping assembly 17, and the protective cover 19 is rotated to cover the part of the material that needs to be cut. When the cutting operation is not performed, the spring structure between the rocker arm 2 and the connecting seat 23 makes the rocker arm 2 on the side away from the base 1, and the two opening and closing covers 7 are kept in a closed state under the action of the torsion spring 8, so as to cover the side of the cutting blade 11 away from the outer protective shell 3. When the cutting operation is required, the rocker arm 2 is pressed downward by the handle 13, and the control switch on the handle 13 is pressed at the same time to start the servo motor 12 and drive the cutting blade 11 to rotate. During the downward rotation of the rocker arm 2 around the connecting seat 23, the second wire rope 10 and the first wire rope 9 pull the two opening and closing covers 7, so that the opening and closing covers 7 rotate into the cavity formed by the outer protective shell 3 and the inner protective shell 4, and the two opening and closing covers 7 gradually release the covering of the cutting blade 11, so that the cutting blade 11 is away from the outer protective shell 3. One side of the protective shell 3 leaks outward, and the high-speed rotating cutting blade 11 contacts the material and cuts it. After the cutting is completed, the pressure on the rocker arm 2 is stopped, and the rocker arm 2 rotates upward under the action of the spring structure. The opening and closing cover 7 is reset under the action of the torsion spring 8, and gradually covers the cutting blade 11. After the rocker arm 2 rotates to the top, the opening and closing cover 7 is completely closed. Through the cooperation among the base 1, the rocker arm 2, the outer protective shell 3, the inner protective shell 4, the sleeve 5, the connecting ring 6, the opening and closing cover 7, the torsion spring 8, the first steel wire rope 9, the second steel wire rope 10, the cutting blade 11, the servo motor 12, the handle 13 and the connecting seat 23, during the up and down rotation of the rocker arm 2, the opening and closing cover 7 can be opened and closed accordingly, forming a larger coverage of the cutting blade 11, thereby improving the protection effect of the cutting machine. When the cutting blade is broken, the probability of intercepting the flying fragments can be increased through the opening and closing cover 7, thereby reducing the probability of the cutting blade splashing and causing harm to the operator.
