Pressing wheel lifting mechanism, traction device and sewing machine

The invention relates to the technical field of sewing machines, in particular to a pinch roller lifting mechanism, a traction device and a sewing machine, one pinch roller lifting mechanism comprises a control assembly, and the control assembly provides two control modes of the traction device for a sewing worker, so that when the limb of the sewing worker is tired, the other control mode can be switched, fatigue is relieved, and the sewing efficiency is improved. Meanwhile, the two control modes do not influence each other, operation resistance caused by transmission of the control mechanism is reduced, and influence on use experience is avoided. 本申请涉及缝纫机的技术领域，尤其是涉及一种压轮提升机构、牵引装置及缝纫机,其中一种压轮提升机构包括控制组件，控制组件给缝纫工人提供牵引装置的两种控制方式，使缝纫工人在肢体疲惫时，得以切换另一种控制方式，缓解疲惫，与此同时，两种控制方式之间互不影响，减少由于控制机构传动带来的操作阻力，避免影响使用体验。
