Description

A kind of multi-functional knife

Technical field

The utility model belongs to a kind of schooling apparatus, particularly cuts, is measured as the apparatus of characteristics.

Background technology

In daily learning life, pocket knife is to use and the common tool that sharpens a pencil, cuts article, because the blade back is thinner, minor particularly students in middle and primary schools is often cut painful even incised wound in use, again because used in everyday more as schooling apparatus such as ruler, angle boards, carry, use the comparatively inconvenience of these instruments, can not reach schooling apparatus comprehensive utilization, convenient and safe purpose.

The utility model content

The purpose of this utility model provides a kind of multi-functional knife, and this multi-functional knife is safe in utilization, and can measure length and angle.

The technical solution of the utility model is, a kind of multi-functional knife, comprise hilt, blade, connecting axle, it is characterized in that: blade back one side has sheath, on blade back opposite side and the hilt scale is arranged, connecting axle is a hollow, and the direction of corresponding connecting axle has elongated hole in the middle of the blade, with the connecting axle is the center of circle, and angle mark is arranged on the hilt.

Described hilt is that transparent material is made, the underlined line of direction of the corresponding connecting axle of described blade.

Blade back one side has sheath, increased the thickness at blade back, can prevent that blade from cutting painful even the incised wound hand, on blade back opposite side and the hilt scale is arranged, can use as ruler, connecting axle is a hollow, the direction of corresponding connecting axle has elongated hole in the middle of the blade, with the connecting axle is the center of circle, and angle mark is arranged on the hilt, can be used for taking measurement of an angle.

When hilt is that transparent material is made, during the underlined line of the direction of the corresponding connecting axle of blade, can more conveniently be used to take measurement of an angle.

The beneficial effects of the utility model are: because blade back one side of the multi-functional knife that the utility model provides has sheath, increased the thickness at blade back, can prevent that blade from cutting painful even the incised wound hand, on blade back opposite side and the hilt scale is arranged, can use as ruler, connecting axle is a hollow, the direction of corresponding connecting axle has elongated hole in the middle of the blade, with the connecting axle is the center of circle, and angle mark is arranged on the hilt, can be used for taking measurement of an angle.Reached the purpose of pocket knife safety easy to use, diverse in function.
