The telescopic rod of the third actuator cylinder (1201) is connected to the first movable plate (123).

8. The ultrasonic cutting device according to claim 6, characterized in that: The cutting device (13) includes a first cutter (131) rotatably mounted on a first movable plate (123) and a cutting actuator (132) for driving the first cutter (131) to rotate.

9. The ultrasonic cutting device according to claim 6, characterized in that: The fabric pulling device (14) is located on the first crossbeam (121) and faces the feeding device (11). The fabric pulling device (14) includes a first fabric pulling execution cylinder (141) installed on the first crossbeam (121), a first fabric pulling clamp (142) with a telescopic rod fixedly installed on the first fabric pulling execution cylinder (141), a second fabric pulling execution cylinder (143) fixedly installed on the first fabric pulling clamp (142), and a second fabric pulling clamp (144) with a telescopic rod fixedly installed on the second fabric pulling execution cylinder (143). The first fabric-pulling clamp (142) and the second fabric-pulling clamp (144) can form a space for clamping the fabric. When the second fabric-pulling cylinder (143) drives the second fabric-pulling clamp (144) to move towards one end of the first fabric-pulling clamp (142), the first fabric-pulling clamp (142) and the second fabric-pulling clamp (144) can clamp the fabric.

10. The ultrasonic cutting device according to claim 6, characterized in that: The first crossbeam (121) is equipped with a labeling device (16).
