[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a cutting device with a limiting structure, including a cutting platform 1, a gantry frame 2 fixedly installed in the middle of the upper surface of the cutting platform 1, an electric push rod 3 fixedly installed on the inner wall of the top of the gantry frame 2, a push bracket 4 fixedly installed at the output end of the electric push rod 3, a rotatable push rod 5 provided on the outer side of the push bracket 4, a rotatable lifting bracket 6 provided at the bottom of the push rod 5, a cutting scissors 7 fixedly installed on the inner side of the lifting bracket 6, an elastic pressing device 8 fixedly installed on the outer side of the cutting scissors 7, L-shaped fixing plates 9 fixedly installed on both the left and right sides of the upper surface of the cutting platform 1, a slidable U-shaped pull rod 10 provided inside the L-shaped fixing plate 9, a pressing spring frame 11 fixedly installed at the bottom end of the U-shaped pull rod 10, a pressing cross plate 12 fixedly installed on the lower surface of the pressing spring frame 11, and a positioning rod 13 inserted into the U-shaped pull rod 10 penetrating through the top of the L-shaped fixing plate 9.

[0021] The elastic pressing device 8 includes a fixed horizontal plate 801 fixedly installed on the left and right sides of the cutting scissors 7. An elliptical fixing block 802 is fixedly installed on the outer side of the fixed horizontal plate 801. A sliding pressing vertical plate 803 is provided inside the elliptical fixing block 802. A fixed bracket 804 is fixedly installed at the bottom of the pressing vertical plate 803. A rotatable pressing rod 805 is provided at the top of the fixed bracket 804. A movable plate 806 is fixedly installed at the top of the pressing rod 805. A compression spring 807 connected to the outer side of the elliptical fixing block 802 is fixedly installed on the outer side of the movable plate 806.

[0022] Specifically, such as Figure 1 and Figure 2As shown, the bottom of the outer surface of the U-shaped pull rod 10 has multiple sets of positioning through holes. The size of the positioning through holes is adapted to the size of the positioning rod 13. The positioning through holes at the bottom of the outer surface of the U-shaped pull rod 10 cooperate with the positioning rod 13 to improve the positioning stability. Support legs are fixedly installed at the four corners of the lower surface of the cutting platform 1. The height of the support legs is 150 mm. The support legs at the four corners of the lower surface of the cutting platform 1 help to provide more stable support. The top of the L-shaped fixing plate 9 has a circular through hole. The size of the circular through hole is adapted to the size of the U-shaped pull rod 10. The circular through hole at the top of the L-shaped fixing plate 9 cooperates with the U-shaped pull rod 10 to improve the convenience of pulling.

[0023] Specifically, such as Figure 3 As shown, there are four sets of pressing vertical plates 803. The lower surface of each of the four sets of pressing vertical plates 803 is provided with anti-slip texture. The anti-slip texture on the lower surface of the four sets of pressing vertical plates 803 increases the friction and improves the anti-slip effect.

[0024] The working principle of this utility model is as follows:

[0025] S1. Place the textile to be cut on the cutting platform 1, control the U-shaped pull rod 10 to drive the pressing spring frame 11 and the pressing horizontal plate 12 to move downward to press and fix the textile, and then insert the positioning rod 13 into the U-shaped pull rod 10 to position the pressing horizontal plate 12.

[0026] S2. Then start the electric push rod 3. The output end of the electric push rod 3 drives the push bracket 4 to move. The push bracket 4 drives the push rod 5 to move. The push rod 5 drives the lifting bracket 6 to move. The lifting bracket 6 drives the cutting scissors 7 to move downward to cut the textile.

[0027] S3. As the cutting scissors 7 moves downward, the fixed horizontal plate 801 and the pressing vertical plate 803 press and fix the textile under the action of the elastic force of the compression spring 807.

[0028] In summary, this cutting device with a limiting structure, by setting the cutting blade 7 to move downwards while driving the fixed horizontal plate 801 and the pressing vertical plate 803 to press and fix the textile under the action of the compression spring 807, provides a better pressing and fixing effect on the textile, effectively preventing wrinkles and displacement of the textile during cutting, enabling more precise and stable cutting operations, and improving the convenience of cutting textiles.

[0029] This cutting device with a limiting structure uses a U-shaped pull rod 10 and a pressing spring frame 11 to move the pressing horizontal plate 12 downwards to press and fix the textile. The positioning rod 13 positions the pressing horizontal plate 12, which provides better pressing stability for the textile, enables more effective fixing of the textile, facilitates more stable cutting of the textile, and effectively improves the convenience of use.
