The mounting block 3 is fixed at the end of the output shaft of the electric telescopic rod 2. The electric telescopic rod 2 is used to drive the movement of the mounting block 3 and the blade 4, which has been disclosed in the comparative document and will not be elaborated here. The mounting block 3 is used to install the connecting block 5;
[0023] In this embodiment, a slot is provided at the lower end of the mounting block 3. An electric push rod 6 is fixedly inserted at the inner top of the slot, which is used to drive the connecting block 5 to lift and lower. The upper end of the electric push rod 6 penetrates through the mounting block 3. The connecting block 5 is slidably inserted on the inner side wall of the slot. The lower end of the electric push rod 6 is fixedly connected to the upper end of the connecting block 5. The lower end of the connecting block 5 penetrates through the slot. The blade 4 is fixed at the lower end of the connecting block 5. A guiding rod 7 is slidably inserted at the inner top of the slot, which is used to keep the connecting block 5 lifting and lowering in a straight line. The upper end of the guiding rod 7 penetrates through the mounting block 3. The lower end of the guiding rod 7 is fixedly connected to the upper end of the connecting block 5;
[0024] In this embodiment, chutes are provided on both sides of the mounting block 3. Sliders 12 are slidably connected to the inner side walls of the chutes, which are used to drive the support blocks 11. An arc-shaped groove is provided on the outer side wall of the slider 12. A ball is rotatably connected to the inner side wall of the arc-shaped groove, which is used to reduce the resistance when the slider 12 slides and moves. Part of the ball penetrates through the arc-shaped groove. A limiting rod 13 is slidably inserted into the slider 12, which is used to prevent the slider 12 from completely disengaging from the chute. The upper and lower ends of the limiting rod 13 respectively penetrate through the slider 12 and are fixedly connected to the inner side wall of the chute;
[0025] In this embodiment, a spring 14 is sleeved on the limit rod 13 to apply a downward pressure to the slider 12. The spring 14 is located above the slider 12. One end of the slider 12 penetrates through the sliding groove. A support plate 11 is fixedly connected to the lower end of the slider 12 to support the positioning wheel 8. A groove is provided at the lower end of the support plate 11. The positioning wheel 8 is arranged in the groove. The lower end of the positioning wheel 8 penetrates through the groove. A support rod 10 is arranged between the positioning wheel 8 and the inner side wall of the groove to prevent the positioning wheel 8 from completely detaching from the groove. The positioning wheel 8 is rotatably connected to the inner side wall of the groove through the support rod 10. A rubber pad 9 is fixedly connected to the outer side wall of the positioning wheel 8 to increase the friction between the positioning wheel 8 and the fabric and improve the clamping and positioning effect.
[0026] In this embodiment, a pressing block 15 is slidably sleeved on the upper end of the limit rod 13 to press down the spring 15. The pressing block 15 is slidably connected in the sliding groove. An adjusting rod 16 is inserted into the lower end of the pressing block 15 to drive the pressing block 15 to move up and down. The adjusting rod 16 is threadedly connected to the pressing block 15. The upper end of the adjusting rod 16 sequentially penetrates through the pressing block 15 and the mounting block 3. The adjusting rod 16 is rotatably connected to the pressing block 3. A knob is fixedly connected to the upper end of the adjusting rod 16 to facilitate the user to rotate the adjusting rod 16.
[0027] In this embodiment, first, the electric telescopic rod 2 drives the mounting block 3 to move, the mounting block 3 drives the blade 4 to move, and the blade 4 moves to perform a cutting operation on the fabric. At the same time, the elastic force of the spring 14 pushes the slider 12 downward, the slider 12 drives the support block 11 to descend, the support block 11 drives the positioning wheel 8 to press down the fabric. Affected by the frictional force, the positioning wheel 8 will move synchronously with the blade 4, thereby preventing the displacement and skew of the fabric during the cutting process, and further avoiding inconsistent cutting sizes. At the same time, manually rotate the knob to drive the adjusting rod 16 to rotate. The adjusting rod 16 drives the pressing block 15 to move downward through the meshing of the threads. The pressing block 15 compresses the spring 14. The spring 14 further pushes the slider 12 and the support block 11 to descend, thereby increasing the pressing force of the positioning wheel 8 and further preventing the fabric from loosening. At the same time, start the electric push rod 6 to drive the connecting block 5 to move up and down, and the connecting block 5 drives the blade 4 to move up and down, so as to realize the height adjustment of the blade 4.
