[0034] In this embodiment, to achieve the effect of quickly clamping the steel pipe and facilitating the adjustment of the clamping position, a clamping support assembly 6 is designed. Two fixed seats 6-1 and a sleeve 6-2 are provided on the top frame 5. The sleeve 6-2 is fixed laterally. A telescopic support rod 6-3 and a first spring 6-4 are housed inside the sleeve 6-2. The first spring 6-4 can generate a certain supporting pressure on the support rod 6-3. A support sleeve 6-5 is provided at one end of the support rod 6-3 for fixing the steel pipe. A rectangular opening 6-6 is provided on the surface of the frame 1, and a drive screw 6-7 and a moving frame 6-8 are provided inside.

The upper end of the movable frame 6-8 is provided with two pressing sleeves 6-9 corresponding to the position of the support sleeve 6-5. The pressing sleeves 6-9 can move to cooperate with the support sleeve 6-5 to clamp the steel pipe and move it towards the saw blade 4. Cutting can be performed during the movement. The surface of the frame 1 is provided with a pair of movable rods 6-11 and a base 6-12. A second spring 6-13 is installed on the movable rods 6-11. The base 6-12 is used to support the steel pipe. The steel pipe can move on the surface of the base 6-12 to facilitate the adjustment of the cutting position.

[0035] Furthermore, the dust collection assembly 7 includes a dust collection device 7-1, which is mounted on the surface of the frame 1. The output end of the dust collection device 7-1 is provided with an extension pipe 7-2, and one end of the extension pipe 7-2 is provided with a dust collection hood 7-3. The dust collection hood 7-3 is located directly above the saw blade 4. The bottom surface of the dust collection hood 7-3 has an arc-shaped transition structure. Several partition plates 7-4 are provided at the bottom of the dust collection hood 7-3. The partition plates 7-4 have a certain inclination angle. An installation port 7-5 is opened at the top of the dust collection hood 7-3. A filter cover 7-6 is installed in the installation port 7-5. A handle 7-7 is provided at the top of the filter cover 7-6.

[0036] In this embodiment, a dust collection component 7 is designed to collect waste generated during cutting. A dust collection device 7-1 is fixed on the surface of the frame 1. The output end of the dust collection device 7-1 is provided with an extension pipe 7-2 and a dust collection hood 7-3. The dust collection hood 7-3 is located above the saw blade 4 and can generate suction to collect waste during cutting. Multiple inclined partitions 7-4 are provided in the bottom opening of the dust collection hood 7-3. The gaps increase the suction and can better introduce waste. The top of the dust collection hood 7-3 has an installation port 7-5 and a filter cover 7-6 is inserted. The surface of the filter cover 7-6 has a concave structure for filtering and collecting waste. A handle 7-7 is provided on the top of the filter cover 7-6 for easy removal and cleaning.

[0037] Furthermore, both the support sleeve 6-5 and the pressing sleeve 6-9 have a C-shaped semi-circular cross-section.

[0038] In this embodiment, the C-shaped semi-circular structure enables the support sleeve 6-5 and the pressing sleeve 6-9 to firmly clamp the steel pipe in the middle.

[0039] Furthermore, the base 6-12 has an overall W-shaped structure, and the bend of the base 6-12 has an arc-shaped transition surface structure.

[0040] In this embodiment, the W-shaped structure facilitates the sliding of the steel pipe into and out of the base 6-12 during lateral movement.

[0041] Furthermore, the spacing between the support sleeves 6-5 and the opening size of the center groove 6-10 are slightly larger than the thickness of the saw blade 4.

[0042] In this embodiment, by using a slightly larger size, the gap between the saw blade 4 and the saw blade is reduced, so that no vibration is generated during the steel pipe cutting process.

[0043] When processing is required, start the cutting saw 2 to make the saw blade 4 rotate at high speed, place the steel pipe on the base 6-12, and then push to adjust the cutting position. After adjustment, start the drive screw 6-7 to control the moving frame 6-8 to move at a uniform speed. During the movement, the support frame 6-5 clamps the steel pipe with the fixed frame. Continue to move and complete the cutting through the saw blade 4. During the cutting process, start the dust collection device 7-1. The bottom of the dust collection hood 7-3 continuously generates suction to suck the waste into the dust collection hood 7-3 and filter it through the filter hood 7-6. After the cutting is completed, reset and readjust the position of the steel pipe.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
