[0026] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] Reference Figure 1-Figure 8 , a profile saw for cutting, comprising a housing 1, and safety components are arranged on both end side walls of the housing 1;

[0028] The safety component includes a mounting block 2, a slide bar 3, a slider 4, a slide column 5, a push rod 7, a control block 8, and a baffle 9. The two mounting blocks 2 are symmetrically fixedly connected to the inner wall of the shell 1, the slide bar 3 is fixedly connected to the side wall of the mounting block 2, the slider 4 is slidably connected to the outer surface of the slide bar 3, the slider 4 is provided with a through hole matching the slide bar 3, the slider 4 is slidably connected to the inner wall of the shell 1, the slide column 5 is fixedly connected to the side wall of the slider 4, the side wall of the shell 1 is provided with a straight groove, the slide column 5 is slidably connected in the straight groove, one end of the push rod 7 is fixedly connected to the side wall of the slider 4, and the other end is fixedly connected to the baffle 9, the push rod 7 is L-shaped, the movement of the slider 4 drives the push rod 7 to move, and the control block 8 is fixedly connected to the side wall of the shell 1.

[0029] The safety component also includes a clamping block 6, a ring 10, and a reset spring 11. The clamping block 6 is fixedly connected to the side wall of the slider 4, and the clamping block 6 is slidably connected to the outer surface of the slide rod 3. The shape of the clamping block 6 matches the aluminum rod. By replacing different clamping blocks 6, aluminum rods of different shapes and diameters can be clamped. The ring 10 is slidably connected to the outer wall of the shell 1. A plurality of arc grooves are provided on the side wall of the ring 10. The slide column 5 is slidably connected in the arc groove. Through holes matching the ring 10 are respectively provided at both ends of the shell 1. The aluminum rod is inserted from the through holes. The internal entry device, the return spring 11 is fixedly connected between the mounting block 2 and the slider 4, and the two clamping blocks 6 are in contact with each other when not in use. The circular ring 10 is rotated. Under the action of the arc groove of the circular ring 10 and the straight groove of the shell 1, the sliding column 5 moves linearly in the direction away from the center of the circular ring 10, driving the slider 4 to move and driving the clamping block 6 to move. The two clamping blocks 6 move away from each other, and the aluminum rod passes through the hole of the circular ring 10. The circular ring 10 is released, and the return spring 11 drives the slider 4 to reset, and the clamping block 6 clamps and seals the aluminum rod.

[0030] The lower end surface of the shell 1 is fixedly connected to the bottom plate 12, the lower end surface of the bottom plate 12 is provided with a conical tube, the lower end surface of the conical tube is provided with a dust box, the upper end surface of the shell 1 is provided with a fan, the dust box collects the cut waste residue, the side wall of the dust box is provided with small holes to allow water to flow out but not the waste residue, and a filter element is provided in the air outlet pipe of the fan to filter the toxic gas.

[0031] A fixing block is arranged on the inner wall of the shell 1, and a cutting saw 13 is fixedly connected to the upper end face of the fixing block, and a handle 14 is fixedly connected to the side wall of the cutting saw 13. A matching groove is opened on the side wall of the shell 1, and the end of the handle 14 away from the cutting saw 13 slides in the groove. Rotating the handle 14 can drive the cutting saw 13 to move so as to cut the aluminum rod. The groove allows the handle 14 to pass through, and the aluminum rod can be cut through the shell 1.

[0032] One end of the sliding column 5 away from the slider 4 is fixedly connected to a limiting block, which limits the ring 10 so that it will not fall off the shell 1. A transparent observation window is provided on the side wall of the shell 1, and the transparent observation window can be used to observe the interior through the shell 1, so that the aluminum rod can be cut through the shell 1.

[0033] A slide groove is provided on the side wall of the control block 8, and the baffle 9 is slidably connected in the slide groove. Both ends of the control block 8 are fixedly connected with water pipes. A through hole is provided inside the control block 8, and water flows through the through hole. A hole matching the through hole is provided inside the baffle 9. When the aluminum rod is not clamped, the baffle 9 blocks the through hole and the water cannot pass through. When the aluminum rod is clamped, the slider 4 drives the push rod 7 to move up and drives the baffle 9 to move up, so that the water flows through the hole of the baffle 9. The larger the diameter of the aluminum rod, the greater the upward movement of the slider 4, and the greater the water flow, until the two holes coincide and reach the maximum flow. A nozzle 15 is fixedly connected to the inner wall of the shell 1, and the control block 8 and the nozzle 15 are connected through a water pipe. Water flows into the nozzle 15 to cool the aluminum rod being cut and eliminate sparks and toxic gases. The thicker the diameter of the aluminum rod, the more water is sprayed, and conversely, the thinner the diameter of the aluminum rod, the less water is sprayed.

[0034] The utility model is used when the ring 10 is first rotated. Under the action of the arc groove of the ring 10 and the straight groove of the shell 1, the slide column 5 moves linearly in the direction away from the center of the ring 10, driving the slider 4 to move and the clamping block 6 to move, and at the same time driving the push rod 7 to move up and drive the baffle 9 to move up, so that the water flows through the hole of the baffle 9, and the water flows into the nozzle 15 to cool the aluminum rod and eliminate sparks and toxic gases. The two clamping blocks 6 move away from each other, and the aluminum rod passes through the hole of the ring 10. The ring 10 is loosened, and the reset spring 11 drives the slider 4 to reset. The two clamping blocks 6 clamp and seal the aluminum rod. At the same time, the interior of the shell 1 is observed through the transparent observation window, and the handle 14 is pulled to drive the cutting saw 13 to cut the aluminum rod. The waste slag flows into the dust collecting box under the action of the water flow, and the waste gas is eliminated by the fan. The operation is performed across the shell 1, which reduces the harm to personnel and the environment and eliminates the safety hazards during production. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
