[0029] Reference Figure 1-2 Furthermore, the electric telescopic rod 104 is electrically connected to the battery through the control panel of the cutting machine 1.

[0030] Embodiment 2:

[0031] like Figure 6As shown, in the utility model, a limit block 204 is fixedly installed below the end of the damping telescopic rod A203, and the limit block 204 is arranged in a semicircular shape, and a limit groove A201 is embedded below the inner wall of the slide groove B2, and there are several limit grooves A201, which are equidistantly arranged in parallel in a semicircular shape, and the limit block 204 is fitted and slidably arranged on the inner side of the limit groove A201. In addition to the embodiment, there is another embodiment in which a limit block 204 is fixedly installed below the end of the damping telescopic rod A203, and the limit block 204 is arranged in an inclined shape around, and a limit groove A201 is embedded below the inner wall of the slide groove B2, and there are several limit grooves A201, which are inclined around and equidistantly arranged in parallel, and the limit The positioning block 204 is slidably arranged on the inner side of the limiting groove A201. When the staff pushes the sliding frame 202 to slide on the inner side of the sliding groove B2 through the slider, the limiting block 204 is squeezed out of the limiting groove A201 to drive the damping telescopic rod A203 and the outer spring to contract. After the sliding frame 202 drives the clamping frame 206 to slide to a suitable position, the damping telescopic rod A203 and the outer spring pop out the limiting block 204 with an inclined shape on all sides and slide into the inner side of one of the relatively inclined limiting grooves A201 on all sides, which will create a larger contact area between the limiting block 204 and the limiting groove A201, and the sliding frame 202 can be limited more stably. Compared with the first embodiment, the limiting and fixing effect is better.

[0032] Working principle: First, when the staff needs to cut the round-edged special-shaped packaging bag cloth, the staff will place the four corners of one of the packaging bag cloth on the clamping frame 206 respectively, and respectively turn the locking screws 3 on the four clamping plates 208 to engage and rotate on the inner side of the thread groove 209, and push the clamping plate 208 to slide downward on the upper part of the inner side of the slide groove C207, so that the clamping plate 208 squeezes and contacts the four corners of the packaging bag cloth, completes the clamping of the packaging bag cloth, and pushes the sliding frame 202 to slide on the inner side of the slide groove B2 through the slider, squeezes the limit block 204 to slide out of the limit groove A201, drives the damping telescopic rod A203 and the outer spring to contract, and makes the sliding frame 202 drive the clamping frame 2 After 06 slides to the appropriate position, the damping telescopic rod A203 and the outer spring pop-up limit block 204 slide into the inner side of one of the relative limit slots A201, and then the positions of the other three clamping racks 206 are adjusted in the same way. The four clamping racks 206 will drive the damping telescopic rod B205 and the outer spring to unfold, so that the unfolded damping telescopic rod B205 and the outer spring will generate pulling force on the corresponding clamping rack 206, driving the packaging bag fabric to unfold. Then, the staff controls the electric telescopic rod 104 to lower the cutting rack A105 to drive the surrounding push racks 109 to contact the surface of the packaging bag fabric respectively, and squeeze the movable rod 108 to rotate through the rotating shaft and the torsion spring, so that the torsion spring While the push frame 109 generates pressure to push the wrinkles of the packaging bag fabric near the cutting part to unfold, the cutting frame A105 descends to the surface of the cutting table 102 to press and contact the packaging bag fabric above, completing the unfolding of the wrinkles of the packaging bag fabric at the cutting part. Finally, the staff pushes the cutting frame B4 to slide out of the slide groove A106, pushes the push rod 407 to slide inside the groove B406 and squeezes the limit frame 405 to drive the damping telescopic rod C408 and the outer spring to contract, and slides the cutting knife 402 to be installed into the installation groove 401, so that the limit groove B403 is close to the limit frame 405, and then releases the push rod 407 to push the damping telescopic rod C408 and the outer spring out of the limit frame 405 slides into the inner side of the limiting groove B403. After the cutting knife 402 is installed, the staff slides the cutting frame B4 into the slide groove A106 to drive the cutting knife 402 to cut the packaging bag cloth from the cutting position and slide into the inner side of the cutting groove 103. The staff pushes the cutting frame B4 to drive the cutting knife 402 to slide between the slide groove A106 and the inner side of the cutting groove 103. After cutting the round edge of the packaging bag cloth, the staff controls the electric telescopic rod 104 to raise the cutting frame A105, and pulls the cutting frame B4 to slide out of the slide groove A106 to remove the cutting knife 402. The staff then removes the packaging bag cloth that has been cut and cuts other packaging bag cloths in the same way.
