Description

Paper folding and creasing knife

Technical Field

The utility model relates to a hand-made tool, especially a paper folding indentation sword.

Background

When the packaging paper box is manually made or the paper is folded, the paper box can be pre-pressed and scratched for the reason that edges and corners are clear and convenient to fold. At present, no special paper folding creasing knife is seen in the market, pre-folding creasing is carried out in a free-hand mode or creasing is carried out by tools such as a knife back tool, the creasing operation process is relatively hard, and slightly carelessly formed creasing is greatly different from expected creasing. The production efficiency and the exquisite degree of the handmade work are influenced.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: an indentation knife for manual paper folding is provided.

The technical scheme for solving the technical problems is as follows: the utility model provides a paper folding indentation sword, includes handle of a knife and tool bit, and the tool bit sets up on the handle of a knife, and handle of a knife one end is equipped with the mounting groove, is equipped with the position fixed slot on the lateral wall of mounting groove, and position fixed slot and mounting groove link up mutually, and tool bit one end is equipped with the bolt through-hole, and the tool bit other end is blunt round point column structure, and the tool bit passes through the bolt and the nut sets up on the mounting groove.

The utility model discloses a further technical scheme is: the knife handle is provided with a storage space.

The back side wall of the mounting groove is arranged on the knife handle through a hinge.

Due to the adoption of the technical scheme, the utility model discloses a paper folding indentation sword has following beneficial effect:

the utility model discloses a handle of a knife and tool bit, tool bit can be changed, have overcome the not enough of current instrument, both can carry out the selection of tool bit according to paper softness and hardness and thickness, can suppress many parallel width's indentation simultaneously as required again.

The technical features of the creasing blade of the present invention will be further described with reference to the drawings and the specific embodiments.

Detailed Description

The utility model provides a paper folding indentation sword, includes handle of a knife 1 and tool bit 2, and the tool bit sets up on the handle of a knife, and handle of a knife one end is equipped with mounting groove 3, is equipped with the position fixed slot on the lateral wall of mounting groove, and position fixed slot and mounting groove link up mutually. Tool bit one end is equipped with the bolt through-hole, and the tool bit other end is blunt round point column structure, and the tool bit passes through the bolt and the nut sets up on the mounting groove, and bolt 4 passes the bolt through-hole 9 on position fixed slot 5 and the tool bit and corresponds the nut 7 fixed tool bit of rotatory combination, and the bolt passes the position fixed slot of mounting groove front side, the bolt through-hole on the tool bit and the position fixed slot of mounting groove rear side in proper order promptly, and the nut that rethread rotatory screwing up and the bolt corresponds is fixed. In order to facilitate installation, the upper end of the cutter head is of a wider flat structure, the bolt through hole is formed in the upper end of the cutter head, so that the width of the upper end of the cutter head is larger than the diameter of the bolt, the lower end of the cutter head is of a blunt-round pointed structure, and the lower end of each cutter head can be set to be different in sharpness, so that indentations of different paper can be used conveniently. When the paper folding creasing knife is used, the knife handle is held by hand, the knife tip of the knife head is used for marking a crease at a place needing creasing, and a ruler and other tools can be attached for positioning if necessary. The tool holder is provided with a storage space 6, the storage space is provided with a cover, and the tool bit, the bolt and the nut can be contained in the storage space. The back side wall of the mounting groove is arranged on the knife handle through a hinge, namely the back side wall of the mounting groove is a clamping piece 8 which can be opened and closed through shaking. The installation of the cutter head is convenient. The number of the cutter heads is multiple, for example, 2-5, and the indentation ends (tips of the lower ends of the cutter heads) of the cutter heads can be in different sizes and sharp structures. During the use, install the tool bit on the mounting groove of handle of a knife one end through the bolt, can install a plurality of tool bits as required, and can adjust the distance between the tool bit as required. The cutter head can be fixed or loosened by rotating the bolt, and the cutter head can be conveniently replaced.
