This utility model discloses a shock-absorbing spoke structure and a wheel. The shock-absorbing spoke includes a tubular spoke, a guide seat, a wear-resistant bushing, and an elastic element. At least one end of the tubular spoke is slidably connected to a guide seat before being connected and fixed to the hub and rim respectively. The guide seat has a guide hole for the tubular spoke to pass through, and the wear-resistant bushing is installed in the gap between the guide hole and the tubular spoke. The wear-resistant bushing has a sliding hole for the tubular spoke to slide through. The elastic element connects the tubular spoke and the guide seat, and provides elastic force to separate the tubular spoke from the guide seat. By setting the wear-resistant bushing between the guide hole and the tubular spoke, a limiting function can be provided to prevent the tubular spoke from shifting or tilting as the wheel rotates. At the same time, the wear-resistant bushing also provides lateral support force to ensure that the tubular spoke can reciprocate and extend along the guide seat and the wear-resistant bushing in the axial direction, and achieves a good shock absorption and buffering effect in conjunction with the elastic element.

The utility model provides a kind of slitting device for corrugated board processing, belong to corrugated board processing technical field, including workbench, blade is inserted on workbench by cutting machine, the side of workbench is equipped with sliding slot, and workbench is slidably provided with support table by sliding slot, support table is used to place stacked paperboard, pressing plate is installed on the top of support table by support frame, and support frame is also equipped with pressing element, its pressing element is used to drive pressing plate to move along vertical direction, to realize the pressing fixation of paperboard;The utility model can replace manual hand-held fixed paperboard, both avoid the security risk that operator is close to blade, also prevent paperboard from deviating and skewing in transfer by stable fixing mode, to improve slitting accuracy and quality, improve slitting operation efficiency simultaneously.
