Description

Technical Field

[0001] The utility model relates to the technical field related to the assembly of indwelling needles, in particular to a riveting and cutting tool. Background Art

[0002] The indwelling needle is mainly composed of a needle tube, a needle tube seat, a sleeve, a sleeve seat, an isolation plug and a rivet, wherein the connection process of the sleeve seat, the sleeve and the rivet is as follows: after the rivet is connected to one end of the sleeve, the sleeve is sleeved on the rivet seat, and then the sleeve seat is also sleeved on the rivet seat, at this time, the rivet at the end of the sleeve is located in the sleeve seat, the riveted part of the rivet edge corresponds to the bottom surface of the edge of the sleeve seat end, and then the sleeve seat end is manually hit with a shaping block, so that the edge of the sleeve seat and the riveted part of the rivet are riveted together to achieve riveting of the two, and then the excess length of the sleeve is cut off with scissors. The sleeve connected with the rivet is assembled manually with the sleeve seat, resulting in low production efficiency; the excess length of the sleeve is manually cut off with scissors, and the length of the sleeve left is different. If the sleeve length is too short, it will result in defective products. If it is too long, it needs to be cut twice, which affects production efficiency. Utility Model Content
