[0030] Embodiment 2:

[0031] See also Figures 1-6 This embodiment provides a technical solution based on the first embodiment: the mounting plate 18 is fixedly mounted with first mounting blocks 21 on both sides of the cutting blade 25, and the bottom ends of the two groups of first mounting blocks 21 are provided with first spring grooves 22, and a first slider 23 is slidably mounted inside each group of first spring grooves 22, and a plurality of groups of first springs 24 are fixedly mounted on the top of each group of first spring grooves 22, and the bottom end of each group of first springs 24 on the same side is fixedly connected to the top end of the first slider 23 on the corresponding side.

[0033] Rubber pads 33 are fixedly installed at the four corners of the bottom end of the frame 1.

[0034] When using this device to cut the curtain, the first slider 23 is set to contact both sides of the cutting position before the cutting blade 25 cuts the curtain. Then, under the action of the first spring 24, it squeezes both sides of the cutting position of the curtain, making the cutting position of the curtain tense, thereby improving the cutting efficiency of this device. In addition, when the curtain passes through the set L-shaped plate 27, the set pressing wheel 32 squeezes the edge of the curtain under the action of the second spring 31, thereby making the movement of the curtain more stable. The rotational connection of the pressing wheel 32 also does not prevent manual pulling of the curtain while squeezing the curtain.
