Description

  The present invention relates to a multi-purpose tool, and more specifically, it is possible to replace various tools such as a spanner, a reinforcing bar tie, and a hammer in a wire cutter (Wirecutter) at a construction site. The present invention relates to a versatile tool with improved performance.

  In general, a variety of construction methods are used at the construction site, but the most common construction method that is often used for housing and building construction is to place concrete inside the formwork to build the building framework. The construction method that completes has become the mainstream.

  In the above construction method, concrete mixing and placing work can be done easily using a mechanical device such as Remicon, but the rebar binding work used to strengthen the concrete stress, the installation of the formwork And removal work etc. depend entirely on the manual work of field workers.

  Tools mainly used for the above operations include a wire cutter, a reinforcing bar binding machine that binds iron wires at the intersection of reinforcing bars, a spanner that tightens or loosens the bolts of the formwork, and a hammer that easily hits a nail.

  Therefore, it is inconvenient for workers who are working on the construction site to always prepare and carry several tools for various purposes, and it is economical to purchase these tools. Problems such as the need for a large expense are generated.

  In particular, there is an inconvenience that it is necessary to always check the number of tools after the work is completed to prevent the tools from being lost.

  The present invention has been created in consideration of the above-mentioned problems, and its purpose is to enable various tools such as spanners, reinforcing bar binding tools and hammers to be replaced with wire cutters at the construction site. The object is to provide a versatile tool with improved convenience.

  A feature of the present invention for achieving the above-described object is that a pair of cutting blades 12 are connected to the upper portions of the both-side handles 11 connected from the central shaft 11a by movable shafts 12a, and pass through the center of each cutting blade 12. A wire cutter 10 in which each fixed shaft 13a is fixed by a support piece 13; a reinforcing bar binding tool formed at a lower part of a one-side handle 11 of the cutting machine 10 and having a sharp support portion 21 bent gently. 20 and; a multipurpose tool in which a bolt is inserted and rotated at the lower part of the other handle 11 of the cutting machine 10; and the reinforcing bar binding tool 20 and the spanner 30 are The coupling tool 22 is integrally formed so as to be sandwiched between the handles 11, and the coupling tool 22 is coupled to the handle 11 of the wire cutter 10 so that each tool can be exchanged and used. It can be achieved by a multi-purpose tool to be.

  As described above, according to the present invention, the wire cutter 10 can be used by exchanging the reinforcing bar binding tool 20, the wrench 30, the hammer, etc., and the iron wire can be used by one tool 1 having a versatile function. It has advantages such as cutting, rebar bundling, bolt tightening and loosening, nail punching, and other advantages. At the same time, when one tool is damaged, it can be used by replacing only the damaged tool. Therefore, it is very easy to use, store and carry the tool 1 while maintaining the overall cost of manufacturing the tool at a low cost, completely eliminating the various problems of conventional tools, and building work. There is an advantage that the external competitiveness of the tool 1 can be increased.

  Hereinafter, preferred embodiments for achieving the above object will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 1 to 5, the multipurpose tool 1 according to the present invention has a configuration in which a reinforcing bar binding tool 20 and a spanner 30 can be replaced with a wire cutter 10.

  The cutting machine 10 is axially coupled by a central shaft 11a penetrating the connecting portion of the both-side handles 11, and when the both-side handles 11 are operated inward and outward, the upper portion of the handle 11 is constricted on the inside or on the outside. It is configured to be opened.

  A pair of cutting blades 12 are connected to the upper part of the handle 11, and the cutting blades 12 are connected by movable shafts 12 a penetrating the upper part of the handle 11.

  A fixed shaft 13a is penetrated in the center of the cutting blade 12, and both fixed shafts 13a are connected to each other by a support piece 13 and fixed.

  Therefore, when the both side handles 11 are pushed inward, the upper part of the handle 11 can be opened with the central axis 11a as the center, and the lower part of the cutting blade 12 connected from the movable shaft 12a is thereby opened on both sides. At the same time, the iron wire inserted between the cutting blades 12 is cut when the upper portion of the cutting blade 12 is narrowed inward with a fixed shaft 13a fixed to the support piece 13 as the center.

  The reason why the both-side cutting blade 12 is not directly connected to the handle 11 in this way and the stage of the movable shaft 12a and the fixed shaft 13a is passed is that the force applied to the handle 11 is weak due to the principle of the lever installed continuously. Also, the force applied to the cutting blade 12 is strengthened so that the iron wire can be easily cut.

  The rebar tying member 20 is formed with a gently bent and pointed support part 21 at the lower part, and a connecting part 22 is integrally formed at the upper part so as to be sandwiched by the handle 11 of the cutting machine 10. Yes.

  When the support portion 21 of the binding tool 20 is inserted and rotated between the knots of the iron wires bundled at the intersections of the reinforcing bars, the connecting portions of the reinforcing bars are firmly fixed while the knots are strongly tightened. The support portion 21 is configured to be easily pulled out from the knot after the end of the support portion 21 is bent and bent outward to complete the binding of the reinforcing bars.

  Further, the coupling tool 22 of the binding tool 20 is configured to be sandwiched between the handles 11 of the cutting machine 10, and when it needs to be replaced due to breakage of the cutting machine 10 or the binding tool 20 when it is replaced with another tool, There is an advantage that only the cutting machine 10 or the binding tool 20 can be exchanged and used.

  In the upper part of the spanner 30, a coupling tool 22 is formed so as to be sandwiched between the handles 11 of the cutting machine 10, and a lower part of the spanner 30 is integrally formed with a bolt inserted and rotated.

  On the other hand, when the projection 14 is formed on one side of the handle 11 of the cutting machine 10, the concave groove 23 is formed inside the coupler 22 so as to correspond to the projection 14, and the coupler 22 is coupled to the handle 11. The coupling member 22 is prevented from being easily detached from the handle 11 by the coupling of the projection 14 and the concave groove 23.

  Further, by integrally forming the reinforcing protrusion 24 inside the coupler 22 so as to correspond to the inside of the handle 11 of the cutting machine 10, the reinforcing protrusion 24 is sandwiched inside the handle 11. The binding of the handle 11 can be strengthened.

  As described above, in the present invention, the binding tool 20 and the spanner 30 are integrally formed on the binding tool 22 sandwiched between the handles 11 of the cutting machine 10. However, tools such as a hammer and a screwdriver are provided on the binding tool 22. It can also be formed integrally.

  The present invention having the above-described configuration is a versatile tool that is absolutely necessary at a construction site by using one tool 1 formed so that the reinforcing bar binding tool 20 and the spanner 30 can be respectively exchanged on both side handles 11 of the wire cutter 10.
