Description
Technical field
The present invention relates to paper cutting field of tool, particularly relates to a kind of safe paper cutters.
Background technology
The existing cutter for cutting paper, its blade is mostly exposed easily to accidentally injure user outside when being cut a sheet of paper using cutter,

Avoid accidentally injuring.
To achieve these goals, present invention employs following technical scheme：A kind of safe paper cutters, including housing,
The interior intracavitary of the housing is provided with chisel holder system and drive device；The drive device includes drive rod and protruding tenon switchs, described
Protruding tenon switch is hinged on inner chamber；The chisel holder system includes tool rest and blade, and blade is on tool rest；The drive rod passes through
Protruding tenon switch is connected with chisel holder system.
Wherein, the lower end of the drive rod, the upper end of tool rest are arranged with spring.
Wherein, the drive rod, which is stretched out on one end top surface of housing, is cased with rubber cushion.
Wherein, the blade front end is provided with point of a knife.
The beneficial effects of the present invention are：It is not easy to scratch user's finger, and for children, it is also safer, together
When, blade portion within the cavity, its exposed situation is avoided, so as to which even children play, the finger of children can not also connect
Blade is contacted, so as to safer.
The cutter does not appear blade when normal, only cut a sheet of paper ruler when paper knife main body compresses auxiliary, the ridge of ruler to
The upper protruding tenon switch for jacking up paper knife, by the effect of lever principle, protruding tenon switch releases downwards the blade of paper knife, promotes
Paper knife is moved along ruler y direction, can cut a paper, and after unclamping paper knife, blade is packed up immediately, will not cause to miss
The danger of wound.
