After the main support block moves to a position near the tube cutting point, the output end of the extrusion cylinder is extended, pressing the extrusion inner block to fix the tube body in place. The main support block is then fixed at the designated position on the tube body. Pulling the fitting block causes the connecting rod to move horizontally to the cutting position, creating a positioning support effect. The rotating side ring is then fitted onto the cutting position of the tube body. The side rotating motor is then controlled... The rotation process drives the transmission gear to rotate, causing the snap-fit ​​side ring to rotate within the positioning ring groove. Supported by the snap-fit ​​bearing, the rotation of the snap-fit ​​side ring is smoother. Simultaneously, the rotation of the side ring controls the extension of the external adjusting cylinder's output end, causing the output end to press against the limiting inner block, extending from the opening of the limiting groove. This allows the side of the blade wheel at one end to press against the outer edge of the tube body, creating a cutting process. The rotation of the side ring causes the blade wheel to perform a progressive cutting process on the tube body. The handheld structure makes operation more convenient, and the positioning rotation cutting structure prevents deviation during rotation, ensuring an uneven cut. Attached Figure Description
