[0032] Refer to Figure 4 , the fixing component includes a U-shaped plate 16, a screw rod 14 is arranged at the bottom of the U-shaped plate 16, a rubber cushion plate 13 is fixedly connected to the top of the screw rod 14. The U-shaped plate 16 provides a basis for the fixation between the hollow block 3 and the workbench 2. The screw rod 14 is connected to the rubber cushion plate 13 and rotates inside the U-shaped plate 16 to make the component abut against the bottom of the workbench 2, realizing the fixation between the hollow block 3 and the workbench 2.
[0033] Refer to Figure 1 、 Figure 2 And Figure 4 , a pulling disc 4 is fixedly connected to the top of the pull rod 5, a disc 8 is fixedly connected to the outside of the connecting rod 9. The pull rod 5 is used to pull the pressing plate 12. The pulling disc 4 is used to facilitate pulling the pull rod 5. The connecting rod 9 is used to connect the limiting plate 11. The disc 8 is used to facilitate one end of the limiting plate 11.
[0034] Refer toFigure 2 At the bottom of the limiting plate 11, a slider 10 is fixedly connected. The slider 10 is slidably connected inside the chute 7. The limiting plate 11 is used to limit the elastic band, and the slider 10 is used to ensure that the limiting plate 11 can slide inside the chute 7.
[0035] Refer to Figure 1 、 Figure 2 and Figure 4 One end of the spring 6 is fixedly connected to the top of the pressing plate 12, and the other end of the spring 6 is fixedly connected to the inner top wall of the hollow block 3. The spring 6 is used to enable the pressing plate 12 to abut against its bottom without external force. The hollow block 3 is used to carry each component inside it to ensure normal operation.
[0036] Refer to Figure 1 - Figure 4 The inner top wall of the U-shaped plate 16 abuts against the top of the hollow block 3, and the rubber backing plate 13 abuts against the bottom of the workbench 2.

As the handle 15 rotates, the rubber backing plate 13 will gradually abut against the bottom of the workbench 2, realizing the fixation between the hollow block 3 and the workbench 2, facilitating the disassembly and installation of the device and improving work efficiency. When it is necessary to stretch the elastic band, by pulling the pull plate 4, the pull rod 5 is driven accordingly, so that the spring 6 is compressed and the pressing plate 12 is pulled up. Then pass the elastic band through the bottom of the pressing plate 12, and then through the sliding disc 8. The disc 8 drives the limiting plate 11 connected by the connecting rod 9, so that the limiting plate 11 slides on the inner bottom wall of the hollow block 3. After adjusting to a suitable position for limitation, release the pull plate 4. Under the action of the spring 6, the pressing plate 12 will press on the elastic band. When the elastic band is stretched to a certain extent, a small section can be automatically released to ensure that the elastic band is tightened while making each part of the sewn product more uniform.
