Abstract: Disclosed are a lower jacking member, a wire withdrawal method based on the lower jacking member, and a squaring machine including the lower jacking member. The lower jacking member is used for axially fixing a bottom surface of an edge scrap formed by cutting a round rod, and a bottom outline of the edge scrap has a cutting edge. The lower jacking member includes at least two single components, and drive structures independently connected to the single components. A spacing between at least one of the single components and the cutting edge is different from a spacing between the rest of the single components and the cutting edge; and the drive structures are used for driving tops of the single components to abut against the bottom surface of the edge scrap.

Abstract: The present application provides techniques for processing bullet screens. The techniques comprises determining a target bullet screen based at least in part on a number of likes received by each bullet screen associated with a target multimedia resource; obtaining attribute information of the target bullet screen comprising a resource time point indicating a time point of displaying the target bullet screen in the target multimedia resource; determining a target time point in the target multimedia resource from which the target multimedia resource starts to play based at least in part on the resource time point; generating prompt information based on the target bullet screen, the attribute information of the target bullet screen, attribute information of the target multimedia resource, and the target time point; and sending the prompt information to a target client computing device.
