The utility model relates to a kind of cursor type paper cutter sweep.

For size at A3 with interior paper, trimming or sanction to cut the size of regulation, can be with the cutting knife type paper cutter work of selling in the market, for the paper of size greater than A3, can be with the work of Large Electric paper cutter in the printing house.But for frequent use, but the cutting of the very little again paper of quantity obviously can not be adopted large-scale paper cutter, resemble the trimming of engineering drawing, the cutting of translucent drawing paper, and present complotter, the large size copier cutting of paper etc. does not all have suitable device to cut a sheet of paper.

The purpose of this utility model is, a kind of cursor type trimmer is provided, and this trimmer has overcome the deficiency of existing Large Electric paper cutter, can be the engineering drawing trimming, but the cutting translucent drawing paper.

For achieving the above object, solution of the present utility model is: the same side at workbench is equipped with support and bar shaped cutter, and pressboard and slide bar are housed on the support; The tapered disk cutter is housed in the vernier on the slide bar, and the relative position of tapered disk cutter and bar shaped cutter relies on the spring in the vernier to guarantee contact, after the paper of needs cutting locates, with the hand vernier that slides, bar shaped cutter and the acting in conjunction of tapered disk cutter are promptly pressed the required size well cutting to paper.

Below in conjunction with accompanying drawing, the utility model is described in further detail.
