[0017] The clamping mechanism 3 includes a moving block 1 301, a moving block 2 302, a slide rail 303, a concave support frame 304, a cylinder 305, a pressure block 306, a rangefinder 307, a baffle 308 and a connecting assembly 309. A slide rail 303 is fixedly connected to the left and right sides of the workbench 2 respectively. The moving block 1 301 and the moving block 2 302 slide on the two slide rails 303. The moving block 1 301 and the moving block 2 302 are connected by a connecting assembly 309. A concave support frame is fixedly connected to the upper surface of the moving block 1 301. The width of the concave support frame is half of the total width of the moving block 1 301. A pressure block 306 is arranged in the concave support frame. Both ends of the pressure block 306 are slidably connected to the concave support frame. A cylinder 305 is fixedly connected to the concave support frame, and the output shaft of the cylinder 305 is fixed to the upper surface of the pressure block 306. The pressing block 306 is pushed down by the cylinder 305 to clamp the fabric to be cut between the pressing block 306 and the moving block 1 301. A rubber pad 4 is fixedly connected to the lower surface of the pressing block 306 and the moving block 1 301. The positions of the two rubber pads 4 correspond to each other. The rubber pad 4 can increase the friction force. A rangefinder 307 is fixedly connected to the concave bracket. The rangefinder 307 is a common laser rangefinder 307 on the market, so it will not be described in detail here. A baffle 308 is fixedly connected to the moving block 2 302. The baffle 308 can block the laser emitted by the rangefinder 307, and the side of the baffle 308 in contact with the laser is flush with the middle position of the moving block 2 302 in the width direction. This position is also the position where the cutter cuts. Setting the baffle 308 here can ensure the accurate reading of the rangefinder 307.

[0018] The connecting assembly 309 includes a connecting bar 1 5, a connecting bar 2 6, a fixed block 1 7, a fixed block 2 8, a slider 1 9, a slider 2 10, a round rod 1 11 and a T-shaped slide rail 12. The fixed block 1 7 is fixedly connected to the moving block 1 301, and the fixed block 2 8 is fixedly connected to the moving block 2 302. The fixed block 2 8 and the fixed block 1 7 are located on the same side. A T-shaped slide rail 12 is arranged on the right side of the fixed block 2 8. The T-shaped slide rail 12 is fixedly connected to the moving block 2 302. The slider 10 slides on the T-shaped slide rail 12, a slide groove 13 is provided on the movable block 301, the slide groove 13 and the fixed block 301 are located on the same side, one end of the round rod 11 is fixedly connected to the slider 9, the round rod 11 slides in the slide groove 13, the other end of the round rod 11 extends into the empty groove 28, and a limiting block 14 is fixedly connected to the round rod 11, and the limiting block 14 is used to limit the round rod 11 from being pulled out of the slide groove 13.

[0019] Further, a slide groove 2 15 is provided in the moving block 1 301, a movable plate 16 is slidably connected in the slide groove 2 15, a protrusion 17 is provided on the movable plate 16, a limit plate 18 is provided on the protrusion 17, and L-shaped limit blocks 19 for limiting the movement of the limit plate 18 are provided on both sides of the limit plate 18, the L-shaped limit block 19 can limit the left and right movement of the limit plate 18, so that the limit plate 18 can only slide up and down, and the bottom end of the L-shaped limit block 19 is higher than the round rod 11, and a limit groove 20 is provided on the limit plate 18, and the round rod 11 is set in the limit groove 20, and the limit groove 20 can limit the round rod 11. For the movement of rod 11, an empty slot three is provided on moving block 1 301, and the empty slot three is located on the opposite side of empty slot 1 28. A round rod 21 is fixedly connected to the movable plate 16, and one end of the round rod 21 is fixedly connected to the movable plate 16, and the other end of the round rod 21 extends out of the empty slot three. A thread is provided on the side where the round rod 21 extends out of the empty slot three. A tightening handle 3123 with matching thread is provided on the round rod 21. The movement of the movable plate 16 can be limited by tightening the tightening handle 3123, thereby limiting the movement of the round rod 11, so that the distance between the movable block 1 301 and the movable block 2 302 is locked.

[0020] Furthermore, a connecting rod 24 is provided on the limiting plate 18, and the limiting plate 18 is rotatably connected to the connecting rod 24. A sliding groove 25 is respectively provided on the left and right sides of the moving block 1 301, and the two ends of the connecting rod 24 slide in the sliding grooves 25 on the left and right sides. A lever 26 is provided on the moving block 1 301, and the lever 26 is hinged to the moving block 1 301. One end of the lever 26 extends into the moving block 1 301, and a waist-shaped groove 27 is provided on the lever 26 extending into the moving block 1 301. The connecting rod 24 slides in the waist-shaped groove 27, and the other end of the lever 26 passes through the moving block 2 302 and extends to the rear of the moving block 2 302. An empty groove 28 for the lever movement is provided on the moving block 2 302, and the upper surface of the lever 26 is connected to the empty groove 28. The lower surface of 28 fits in, which plays a role of limiting. During the process of loading textiles, the lever 26 can be pulled to move the clamping device as a whole to the rear side of the cutting machine body 1 for easy loading. However, if the moving block 2 302 is pulled to the limit distance and it is found that the distance between the moving block 2 302 and the moving block 1 301 is far, and it is still inconvenient to load the materials, the lever 26 is bent downward, and the lever 26 can drive the connecting rod 24 to move upward, so that the limiting plate 18 moves upward, and the round rod 11 becomes movable. At this time, the staff presses the moving block 2 302 with one hand and pulls the lever 26 with the other hand to pull the distance between the moving block 2 302 and the moving block 1 301. After releasing the lever 26, the lever 26 returns to its original position under the action of the tension spring 29.

[0021] Furthermore, a handle 31 is fixedly connected to the limit plate 18, one end of the handle 31 is fixedly connected to the limit plate 18, and the other end of the handle 31 extends out of the moving block 301. A slide groove 5 30 is provided on the upper surface of the moving block 301, and the slide groove 5 30 is located on the rear side of the concave bracket. The handle 31 slides in the slide groove 5 30. Since pulling the lever 26 will cause the round rod 11 to lack a limit and cannot be fixed, when it is necessary to re-limit the round rod 11, the fastening handle 3123 can be loosened, and then the handle 31 is pulled to raise the limit plate 18, and the handle 31 is slid to the top of the round rod 11 and the handle 31 is loosened, so that the round rod 11 is re-limited.

[0022] Furthermore, a blocking block 32 is fixedly connected to the cutting machine body 1, and the rear end face of the blocking block 32 is on the same plane as the front end face of the blocking block, and slots 33 are provided on both sides of the movable block 302. A magnet is embedded in the rear end face of the blocking block 32, and a magnet 2 is embedded in the slot 33. When the movable block 302 is inserted into the bottom of the slot 33, the magnet 1 and the magnet 2 attract each other, and the movable block 302 will be fixed at this time. At this time, the center position of the movable block 302 is the same as the position cut by the cutter, and empty slots 34 for the blocking block 32 to pass through are provided on both sides of the movable block 1 301.

[0023] Working principle of the invention: by pulling the lever 26, the entire clamping mechanism 3 is pulled to the rear side of the cutting machine body 1, and then one end of the textile to be cut is placed on the rubber pad 4 on the moving block 1 301, and then the pressing block 306 is pushed by the cylinder 305 to press the textile, and then the moving block 2 302 is pushed to the junction of the blocking block 32 and the card slot 33, and then the fastening handle 3123 is loosened to adjust the distance between the moving block 1 301 and the moving block 2 302, and the fastening handle 3123 is tightened after determining the required distance by observing the value on the rangefinder 307, and the cutting machine body 1 is started, and this cycle is repeated.
