Detailed Description

The following further describes the embodiments of the present invention with reference to the drawings (fig. 1, fig. 2, fig. 3, fig. 4) of the present specification.

The utility model consists of a knife handle 0 and a knife body 1 (figure 1).

The outline of the knife handle 0 is a rectangular structure, a U-shaped groove is formed in the knife handle, and the U-shaped groove longitudinally penetrates through the whole knife handle 0. The knife handle 0 is used for accommodating the knife body 1.

One end of the knife handle 0 is provided with a circular mounting hole 4 (figure 2), and the mounting hole 4 penetrates through the groove walls on the two sides of the U-shaped groove.

The outer side of the knife handle 0 is provided with an anti-slip sheet sleeve 3, and the anti-slip sheet 3 has the function of increasing the friction between the novel knife handle and the fingers or palm of a user and preventing the novel knife handle from slipping off the hand of the user.

The knife body 1 has a rectangular outline, and a fixing hole 12 (fig. 3) is formed at the rear end of the knife body. The fixing hole 12 is used for mounting the blade 0 to the holder 1.

The front end of the knife body 1 is provided with a convex block 5. The convex block 5 is a non-edged and non-sharp structure with a small upper part and a large lower part, and is used for cutting the adhesive tape on the package.

The purpose of the top of the bump 5 without an edge or sharp structure is two: firstly, people are prevented from being hurt by sharp edges or sharp structures; second, it avoids the sharp or pointed structure from damaging the goods inside the package when the adhesive tape on the package is scratched.

The arc-shaped structure at the bottom of the front end groove 6 is also the edging part 8 with the arc-shaped structure, so that when the packing belts on the packing materials are cut, the cutting effect of the arc-shaped sickle is actually achieved.

The rear end groove 7 is of an arc structure, and the bottom of the rear end groove 7 is provided with an edging part 10. The opening part 10 serves to cut the carton.

The function is used for the situation when the height is larger than the goods, the edging part 10 of the utility model is utilized to cut the front, the back, the left and the right corrugated boards of the carton to proper positions from the folding positions, and then the carton is folded inwards, so that the carton is tightly attached to the goods.

The width of the rear end groove 7 is preferably not more than 1.5 cm.

This width ensures that the user does not insert a thumb or other digit into the rear slot 7 when grasping the utility model. The danger that the fingers are cut by the sharpening part 10 because the fingers of the misoperation handle are inserted into the rear end groove 7 in the process that an operator uses the utility model is avoided.

The rear end of the knife body 1 is provided with a fixing hole 12.

The diameter of the fixing hole 12 on the knife body 1 is the same as that of the mounting hole 4 on the knife handle 0.

The rear end of the knife body 1 is embedded in a groove in the knife handle 0, and the rotating shaft device 2 penetrates through a mounting hole 4 in the knife handle 0 and then penetrates through a fixing hole 12 in the knife body to mount the knife body 1 on the knife handle 0.

The blade 1 can rotate about the axis of the rotating shaft device 2.

When the adhesive tape on the packing material is scratched, the adhesive tape is kept in a closed state, an operator holds the adhesive tape by hands, and presses the convex block 5 on the adhesive tape to slide along the trend of the adhesive tape.

When the utility model is opened, the knife body 1 is inserted between the packing belt and the packing box, the packing belt is hooked by the opening part 8 of the front end groove 6, and the packing belt can be cut off by pulling forcefully. The nylon rope and hemp rope which are not easy to be cut by the cutting part 8 can be sawed by the saw teeth 9.

When the carton is needed, the rear end groove 7 is only required to be sleeved at the folding angle of the corrugated paper of the carton, and the carton can be pressed downwards.

Compared with common tools such as scissors, small folding knives and paper cutters, when the tool is used for manually packing or unpacking goods, the tool not only integrates the functions of cutting, sawing, scratching and the like, but also is positioned at the bottom of the front end groove 6 because the opening part 8 is positioned at the bottom of the rear end groove 7.

The probability that any human body organ including the operator's finger is in contact with the cutting edge part 8 and the cutting edge part 10 is low, and therefore the present invention has extremely high safety.

In addition, the convex block 5 adopts a non-edged or sharp structure, so that even if the human body is accidentally scratched, serious injury can not be caused.
