I. Field of the Invention
The present invention relates to an industrial-purpose cutter, and particularly, to an integrated cutter used to cut “V-shape” openings, pipes and wires.
II. Description of the Prior Art
Heretofore, it is known that a cutter comprises two forks and two handlebars that can be opened and closed. Of the two handlebars, one end functions as a jaw for cutting and the other end functions as a handle. Under the action of a resilient member, the two handlebars are normally in open status, and when user holds the two handlebars, the jaw is coupled and thus generates cutting operation. The structure of the jaw determines what pattern of cutting operation it will generate. Normally, the jaw has the structure of straight-line cutting.
Due to such restraints as overall size, convenience for operation and cutting force, the jaw of the cutter is usually designed with single cutting function. In other words, one cutter can accomplish no more than one type of cutting. This is not cost-effective because for industrial applications, cutters of different functions are needed for onsite work, and cutters occupy precious working space and are convenient to carry about. In addition, frequent change of cutters in work may cause interruption and delay for work.
It is therefore a primary object of the invention to provide a multifunction cutter that solves the problems of the known prior art. The present invention offers three different cutting functions in limited space.
It is still an object for the invention to provide a cutter used to cut “V-shape” openings, pipes and wires.
In order to achieve the objective set forth, a cutter in accordance with the present invention comprises:
User places the edge of thin plate on the drilling block of the first cutter groove, holds the handheld ends and of the said first and second handlebars and to couple the cutter body with the drilling block, the first cutter groove on the first cutting section will cut a V-shape opening on the edge of the thin plate and the cut-off V-shape piece will fall off below the first cutter groove.
User places a pipe on the pipe drilling block, holds the handheld ends and of the first and second handlebars and to couple the cutter body with the drilling block, the second cutter groove on the second cutting section will cut apart the entire pipe.
User places wire on the wire drilling block, holds the handheld ends and of the first and second handlebars and to couple the cutter body with the drilling block, the third cutting section will directly act on the wire cutting groove; when the third cutting section stops at the drilling rod, it will cut wire apart.
The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
Referring to
A first handlebar 20 in U-shaped in cross section (as shown in
A second handlebar 30, as shown in
A drilling plate structure 40, as shown in
A drilling block 44 is integrated on top of the fixing block 41; the drilling block 44 is partially braced at the bottom by the bracing section 35 and comprises a cutter groove for the cutter body 10 to cut in. For the purpose of description, the cutter groove is subdivided into the first cutter groove 45 and the second cutter groove 46, wherein the first cutter groove 45 is intended for the first cutting section 12 to cut in and the second cutter groove 46 is intended for the second cutting section 13 to cut in. The section of the drilling block 44 where the first cutter groove 45 is located extends beyond fixing block 41 and the first cutter groove 45 constitutes a triangular hole open on both ends; the bottom of the second cutter groove 46 is interconnected with the top of the fixing block 41; the drilling block 44 has a semi-arc drilling groove 47 on the structure corresponding to the said second cutter groove 46 and is intended for holding pipes 52 to be cut, which is referred to as pipe drilling groove 47 in the present invention; there is some distance between the drilling block 44 and the coupling section 32 of the second handlebar 30, and the distance constitutes another drilling groove 48 on drilling plate structure 40 and the drilling groove 48 is intended for holding wires 53 to be cut, which is referred to as wire drilling groove 48 in the present invention; a rigid drilling rod 49 is located on the top of the fixing block 41 corresponding to the cutting position on the first and second cutting sections 13 and 14, and executes cutting functions in coordination with the first and second cutting sections 13 and 14.
The above is the structural form of the cutter in the present invention and below is a description to specific methods concerning its operation and production.
As generally known, to fold thin plates into predefined shape, for example, to fold paper materials of predefined thickness into paper boxes, cartons or corrugated shapes, it is preferred to make a V-shape opening on both ends of the paper materials that are to be folded. The purpose is to eliminate the elasticity of the section, reduce the resilience of folded edges and make thin plates easier to fold and shape. The first cutting section 12, the drilling block 44 and the first cutter groove of the cutter in the present invention have the functions of cutting V-shape openings. As shown in
The size of the V-shape opening depends on the specific location where the edge of thin plate 50 is placed on the drilling block 44. For example, if user places the edge of the thin plate in a way that it fully covers the first cutter groove 45, it will cut a maximum V-shape opening. On the other hand, if user places the edge of the thin plate in a way that it covers a small portion of the first cutter groove 45, it will cut a small V-shape opening.
As shown in
As shown in
As described above, the drilling block 44 is partially braced at the bottom by the bracing section 35, and fixing components 43 fix the fixing block 41 of the drilling block 44 on the bracing section 35 such that fixing block 44 is firmly fixed and can bear the cutting force applied to it by the cutter body 10 without causing instability.
As shown in
Te present invention applies space in the cutter body 10 to provide the first cutting section 12, the second cutting section 13 and the third cutting section 14, and uses the limited space on the drilling plate structure 40 to provide the first cutter groove 45, the second cutter groove 46, the pipe drilling groove 47 and wire drilling groove 48 such that all these structures coordinate with the cutting sections. As a result, the cutter in the present invention can cut V-shape openings, pipes and wires, thus becoming a multifunctional integrated cutter.
While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
