[0032] The adjustment component 4 includes a transmission unit and a limit unit;

[0033] The transmission unit is used to adjust the height of the protective cover 3;

[0034] The limiting unit is used to limit the height of the protective cover 3 after movement;

[0035] The transmission unit includes a limiting rod 401, a rotating rod 402, a gear 403, a rack 404, and a second limiting block 406;

[0036] The top rear end of the workbench 1 is fixedly connected to the fixed base 2. The limiting rod 401 is rotatably connected to the inner wall of the fixed base 2 and extends to the outside of the fixed base 2. The limiting rod 401 drives the rotating rod 402 to rotate synchronously through the second limiting block 406.

[0037] The second limiting block 406 is fixed to the outer wall of the limiting rod 401, and the second limiting block 406 is used to transmit the rotational force from the limiting rod 401;

[0038] The rotating rod 402 is sleeved on the outer wall of the limiting rod 401 and the second limiting block 406, and the rotating rod 402 is used to synchronously drive the gear 403 to rotate;

[0039] The gear 403 is fixed to one end of the rotating rod 402, and the rotating gear 403 is used to push the rack 404 to move vertically;

[0040] The rack 404 is fixed to the outer wall of the protective cover 3 and extends to the inner cavity of the workbench 1. The rack 404 is used to drive the protective cover 3 to move synchronously;

[0041] The limiting unit includes a first limiting block 405 and a limiting groove 407;

[0042] The first limiting block 405 is fixed to the outer wall of the limiting rod 401, and the first limiting block 405 is used to cooperate with the limiting groove 407 to limit the rotation of the limiting rod 401;

[0043] The limiting groove 407 is provided on the outer wall of the fixing base 2, and the limiting groove 407 is used to provide space for inserting the first limiting block 405;

[0044] The outer wall of the rack 404 is in a convex shape as a whole, and a sliding groove 201 for the rack 404 to move vertically is formed on the fixing seat 2.

[0045] In this embodiment, when using this device, the protective cover 3 can shield and protect the working area of the cutting blade 5. The gap between the bottom of the protective cover 3 and the upper surface of the workbench is used for the steel to come into contact with the cutting blade 5 during the cutting operation. The protective cover 3 can intercept the sparks and debris generated by cutting to prevent them from splashing and causing harm to the operator.

[0046] The height of the protective cover 3 can be adjusted to suit the cutting of steel materials of different thicknesses. The operation steps are as follows:

[0047] By applying an outward pulling force to the limiting rod 401, the limiting rod 401 will synchronously drive the first limiting block 405 and the second limiting block 406 to move outward, the first limiting block 405 moves out of the inner cavity of the limiting groove 407, and the second limiting block 406 moves axially along the inner cavity of the rotating rod 402, generating a rotational force that can be applied to the limiting rod 401. The rotating limiting rod 401 will apply a rotational force to the rotating rod 402 through the second limiting block 406, and the rotating rotating rod 402 will synchronously drive the gear 403 to rotate. The rotating gear 403 gives thrust to the rack 404, causing the rack 404 to move vertically along the vertical slide groove 201 in the inner cavity of the fixed base 2, thereby adjusting the height of the protective cover 3. When the adjustment is completed, a thrust can be given to the limit rod 401, and the limit rod 401 will drive the first limit block 405 and the second limit block 406 to move, so that the first limit block 405 enters the inner cavity of a corresponding limit groove 407, completing the rotation limit of the limit rod 401, thereby limiting the height of the protective cover 3.

[0048] Please refer to Figure 2-Figure 5, there are multiple limiting grooves 407, and the multiple limiting grooves 407 are evenly distributed on the outer wall of the limiting rod 401 with the axis of the limiting rod 401 as the midpoint;

[0049] The outer wall of the first limiting block 405 matches the inner cavity of the limiting groove 407. The protective cover 3 is a rectangular structure with a closed top and a transparent structure.

[0050] The inner cavity of the rotating rod 402 is formed with a sliding groove for the second limiting block 406 and the limiting rod 401 to move axially, and the inner cavity of the workbench 1 is formed with a movable groove for the gear 403 to rotate.

[0051] In this embodiment: during the steel cutting process, the transparent protective cover 3 can facilitate observation of the steel cutting situation;

[0052] In addition, when the limiting rod 401 moves outward, the movable second limiting block 406 is still located in the inner cavity of the rotating rod 402 , so that the rotating limiting rod 401 drives the rotating rod 402 to rotate through the second limiting block 406 .

[0053] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
