The present invention relates to the technical field of handicrafts, and in particular relates to a tool for the production of handicrafts.
Craft punch is a tool for the production of handicrafts, which is widely used at present. A traditional craft punch consists of two major parts which are part 1, a lower cutting mold: its production process is as follows: a complete lower cutting mold holder with (negative) cutting shape is produced, wherein the cutting shape penetrates through from the top till the bottom in a hollow form, and then a part on the lower cutting mold holder is horizontally sawn to form a gap. As it is not sawn off completely, the lower cutting mold is still integrated, only the part in the (negative) cutting shape on the lower cutting mold holder is divided into upper and lower parts, and the gap is to allow paper to be inserted; and part 2 is an upper cutting mold which is mainly used for cutting and has a cutting shape the same as that of the lower cutting mold, the upper cutting mold has a positive cutting shape, while the lower cutting mold has a negative cutting shape. The positive cutting shape of the upper cutting mold is placed into the upper part of the lower cutting mold with the negative cutting shape, and the upper cutting mold is pressed hard to the bottom of the lower cutting mold holder so as to cut the shape the same as that of the upper cutting mold and the lower cutting mold on the paper which is inserted into the gap. The part in the (negative) cutting shape on the lower cutting mold holder is horizontally sawn to form a gap, this production method is to make sure that the (positive) cutting shape of the upper cutting mold extends from the upper part of the lower cutting mold holder to the bottom absolutely perpendicularly so as to successfully cut the shape the same as that of the upper cutting mold holder and the lower cutting mold holder on the paper in between. Afterwards, a complete craft punch product could be formed by the upper cutting mold and the lower cutting mold through plastic boxes, accessories and springs used for positioning the upper cutting mold on the upper half part of the lower cutting mold holder as well as other assemblies. Under such a mode of production, a lot of raw materials need to be used to produce a lower cutting mold holder part which is relatively hard enough to bear the force of impact from the upper cutting mold, and a single upper cutting mold holder and a single lower cutting mold holder need to be produced for cutting each shape, so that it is a resource-wasting production method; in addition, as the upper cutting mold needs to extend from the upper part of the lower cutting mold holder to the bottom, the upper cutting mold with enough length needs to be produced, and it is also a kind of waste of resources; in addition, the craft punch product with each single shape could be formed by plastic caps, parts, springs and multiple procedures, which also causes another kind of waste; finally, the traditional craft punch produced in this way is inflexible, and only could be used for cutting on a piece of paper in one direction.
In view of the defects and inconvenience of the known craft punch, adhering to the spirit of innovative research to strive for perfection, the applicant develops a craft punch with a replaceable cutting tool which conforms to industrial application with his professional vision and expertise.
The present invention aims at overcoming the defects of the prior art, and providing a craft punch which is simple in structure, scientific and reasonable, could facilitate the replacement of a lower cutting mold and an upper cutting mold, works more effectively and saves resources.
To achieve the above purpose, the present invention adopts the following technical scheme:
A craft punch with a replaceable cutting tool, comprising:
a main body, having an upper part and a lower part which are spaced up and down, wherein a gap allowing paper to be inserted is formed between the upper part and the lower part, the upper part has a passage, and the lower part has a receiving part to movably receive a lower cutting mold holder;
an upper cutting mold holder receiving component, which could be installed in the passage on the upper part of the main body movably up and down, wherein the upper side of the upper cutting mold holder receiving component bulges to form a tubular part, and one side of the upper cutting mold holder receiving component back to the tubular part is provided with a receiving part which could movably receive an upper cutting mold;
a cover plate, which covers the upper end of the passage on the upper part of the main body, and is provided with a through hole allowing the tubular part of the upper cutting mold holder receiving component to pass through an upper bulge;
an upper cover, which covers the upper side of the cover plate, and is connected with the tubular part of the upper cutting mold holder receiving component.
In the above scheme, the receiving part of the upper cutting mold holder receiving component is provided with a slot allowing the upper cutting mold to be movably inserted and installed, and a positioning structure for positioning the insertion of the upper cutting mold, wherein the positioning structure for positioning the insertion of the upper cutting mold comprises a positioning ball and a small spring which are sequentially installed in a hollow part of the tubular part of the upper cutting mold holder receiving component, the upper cover is provided with a convex column which is inserted into an inlet of the tubular part of the upper cutting mold holder receiving component to eject and press the small spring, the other end of the small spring pushes and ejects the positioning ball to just enable the positioning ball to be partially exposed out of an opening leading to the receiving part of the upper cutting mold holder receiving component, and a part of the positioning ball which is exposed out of the opening is positioned in a matching way corresponding to a recessed position on the back of the upper cutting mold.
In the above scheme, guide ribs for guiding the upper cutting mold holder receiving component to move up and down are installed in the passage on the upper part of the main body, and work in coordination with concave channels at the periphery of the upper cutting mold holder receiving component.
In the above scheme, the receiving part on the lower part of the main body to receive the lower cutting mold holder is provided with a receiving groove and a positioning groove which is intersected with the receiving groove, the lower cutting mold holder is movably inserted with regard to the receiving groove, while spliced by coordinating with a locking member with regard to the positioning groove, and the locking member is used for positioning the insertion of the lower cutting mold holder. The locking member is provided with a convex positioning column which is used for receiving positioning holes in a straight line positioning member and an angle positioning member, in order to realize rapid locking of the straight line positioning member and the angle positioning member.
In the above scheme, a prop for a large spring is arranged between the upper cover and the cover plate, the large spring is sleeved with the tubular part of the upper cutting mold holder receiving component, and a plurality of axial ribs are arranged at the periphery of the tubular part of the upper cutting mold holder receiving component.
The craft punch provided by the present invention is simple in structure, scientific and reasonable, could facilitate the replacement of a lower cutting mold and an upper cutting mold, has high flexibility, works more effectively and saves resources. It is convenient to operate and low in investment cost, greatly improves the operating ratio and operability of the craft punch, conforms to the industrial application, and improves the production efficiency.
