Description

Technical Field

[0001] This utility model relates to the field of stationery design technology, and in particular to a correction tape. Background Technology

[0002] Traditional correction tape nozzles, or correction tips, generally cannot be rotated. Users can only use correction tape with one grip. When the area to be corrected has a slight curve and the correction tape needs to be adjusted to a different angle, the tape body is easily broken if the nozzle cannot be rotated during use.

[0003] Existing technology discloses correction tape with a rotating nozzle, but its drawbacks are: 1. The winding and unwinding pulley structure of the correction tape remains unchanged, but the rotation angle of the nozzle is not large; 2. Some correction tapes are claimed to be able to rotate 360 ​​degrees, but in fact, the entire movement of the correction tape is made to rotate as a whole within the housing. The disadvantage is that the housing must be made into a cylindrical shape, and the correction tape capacity is limited, less than half that of traditional correction tape; 3. There is no cap on the outside of the nozzle, or although there is an independent cap, it is easy to fall off and be lost. Summary of the Invention

A rotation angle stop block is provided on the rotating positioning protrusion two, which cooperates with the rotation angle stop platform on the housing to limit the rotation of the tape nozzle within ±90 degrees.
