Description

  The present invention relates to a keren tool.

  The keren tool has a kelen tool body provided with a kelen blade for removing dirt firmly adhered to the surface, and a rod body for operating the kelen tool body.

  Examples of dirt to be removed by this wide-ranging Keren tool include, for example, welded flying objects formed by dripping molten scattered substances generated during welding attached to the surface of an object to be welded and solidified, and during painting. The coating material scattered on the surface of the material to be coated adheres to the surface of the object to be coated in the form of droplets and solidifies, and may also include an adhesion material on the concrete surface, an adhesive on the surface of the article, iron rust on the surface of the steel material, and the like.

  In a conventional type of tool, known as a Keren rod, which scrapes welded particles and other foreign objects firmly attached to the surface from the surface, the Keren tool body or element is integrated into one end of the rod body or handle. A kelen blade made of cemented carbide is formed at the tip of the kelen tool body (element body). Here, the part other than the kelen blade of the rod body (handle) and the keren tool body is typically integrally formed of steel or the like. The rod body (handle) is formed in the center of the base end portion of the keren tool body without being eccentric.

  When operating this keren tool, the bar body (handle) is grasped by hand, the arm is shaken, and the dirt on the surface is scraped off by the keren blade. When the spread of dirt is large, for example, when using a keren tool with a long and wide kelen tool body, the space around the article surface is narrow or the adhesion strength of the dirt is strong, For example, dirt is removed using a keren tool having a kelen tool body with a short blade length and a narrow width.

  This type of conventional keren tool, usually called a keren rod, is difficult to firmly hold a gripping portion consisting of an intermediate portion of the rod body (handle), so that it is difficult to apply a large force to the keren tool body. Further, in order to remove dirt having different lengths of the keren blades (the width of the keren tool main body), it is actually necessary to carry out the work with a plurality of keren rods at hand. This makes usability worse.

  A tool structure including a tool at both ends of a stick (handle) or a gripping part is known as another peeling tool that performs a kelen work in a broad sense, although it is not a keren stick (for example, Patent Documents 1 and 2). .

  However, the tool structures of Patent Documents 1 and 2 share a bar (handle) or grip portion when using a tool at each end. However, in operation, other tools are used at both ends. Some things are not useful.

  Moreover, although it is not a keren tool, in another tool structure, attaching the tool of both ends with respect to a stick | rod (handle) is proposed (for example, patent documents 3-5).

  However, even in the tool structures of Patent Documents 3 to 5, when the tool body at each end is used, the rod portion is shared, but in operation, there are other tool bodies at both ends. Is not useful.

  A tool structure (Patent Documents 6 to 8) provided with a plurality of peeling tool portions not at both ends but at a plurality of locations has also been proposed.

  However, although these proposals also share a part of the tool structure, it is not useful for the operation to have tool bodies at both ends of the tool structure.

In addition, in the field of keren rods or keren tools, although a plurality of peeling tool portions arranged in an easy-to-hold shape (Patent Document 9) are known, this is branched in order to realize ease of holding. A two-dimensional shape is formed to form a gripping part and a tool part, and it is not intended to make both exchangeable and easy to operate at the time of use.

  The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a kelen tool assembly having kelen blades of different sizes to be used depending on the state of dirt in a state where force can be easily applied. It is to provide.

  In order to achieve the above object, the Keren tool assembly of the present invention is removably attached to a rod body having kelen tool body mounting portions at both ends and the Keren tool body mounting portion of the rod body. A Keren tool assembly having a Keren tool element body, each Keren tool element body is a plate-like Keren tool element body portion having a Keren blade at the tip, and a Keren tool element support shaft portion A rod mounting part on the base end side that is fixed to the tip of the rod body and is detachably attached to the rod body mounting part of the rod body with the base end of the body of the kelen tool body being eccentric in the thickness direction. And have.

  In the Keren tool assembly of the present invention, “a rod body having a Keren tool body mounting portion on both ends and a Keren tool body body detachably attached to each of the Keren tool body mounting portion of the rod body. Each element has a plate-shaped element element body having a blade element at the tip of the element. Therefore, the element elements having elements of different sizes as the element elements at both ends. Therefore, the dirt can be removed by using a kelen tool body having a different size depending on the situation of the dirt, and the dirt can be easily and reliably removed. Further, in the Keren tool assembly of the present invention, “the plate-like Keren tool body main body of each Keren tool body is in the form of a plate with respect to the distal end portion of the Keren tool body support shaft at the base end. The kelen tool body main body includes a kelen blade opposite to the kelen blade that performs the scraping or peeling operation as the keren work. It is possible to grip with a thumb on the end face side exposed by eccentricity of the Keren tool body support shaft part fixed in an eccentric state in the thickness direction, and apply a large scraping force at the time of Keren work Is possible.

  Further, in the Keren rod assembly of the present invention, “the plate-like Keren tool body body portion of each Keren tool body is in relation to the Keren tool body support shaft portion of the plate-like Keren tool body body portion. Since it is eccentric in the thickness direction, it is possible to incline the keren tool body so as to be along the surface on which the keren work is to be performed, and it is easy to remove the firmly adhered dirt.

  In the kelen tool assembly of the present invention, the kelen tool body is detachably attached to the rod body, so that it can be appropriately replaced with an appropriate kelen tool body according to the working environment or object. Also, in the Keren tool assembly of the present invention, the Keren tool body can be replaced, so when the Keren blade is worn or damaged, only the Keren tool body part including the Keren blade can be replaced. It becomes possible, and the waste of cost and resources can be minimized.

  In the Keren tool assembly of the present invention, typically, the Keren tool body support shaft is larger in diameter than the rod body.

  In this case, the Keren tool body support shaft portion is easily gripped more firmly.

  In the Keren tool assembly of the present invention, typically, the Keren tool body support shaft part is provided with a large-diameter end part having a larger diameter at both ends than an intermediate part therebetween.

  In this case, the index finger arranged so as to stick to the portion between the large-diameter end portions of the Keren tool body support shaft portion can be stably supported by the large-diameter end portions on both sides, so that gripping is more easily performed. .

  In the Keren tool assembly of the present invention, typically, of the two large-diameter ends of the Keren tool body support shaft, the large-diameter end closer to the Keren tool body body is eccentric. A radial projecting portion is cut out at a portion on the side where the element body portion is shifted.

  In this case, since the Keren tool assembly including the rod main body can be laid down so as to be almost parallel to the surface from which the dirt is to be removed, it is easy to remove the dirt adhered firmly.

  In the Keren tool assembly of the present invention, typically, the Keren tool body mounting portion of the rod body is concentric with the central portion of the rod body and has an engaging portion on the outer peripheral surface, and the rod mounting portion of the Keren tool body Is provided with a hole portion that is concentric with the outer periphery of the rod mounting portion and has a complementary engagement portion formed on the peripheral surface, and the Keren tool base body portion is fixed to one side portion of the peripheral wall of the hole portion. Yes.

  In this case, since the Keren tool body support shaft part can be made considerably thicker, not only the Keren tool body support shaft part can be firmly gripped, but also the Keren tool body body part can be attached to the Keren tool body part. It becomes easy to make an eccentric arrangement with respect to the element support shaft and to make the keren tool element detachable from the rod body.

  In the Keren tool assembly of the present invention, typically, the rod main body is fitted on the outer periphery of a rigid rod-shaped body having the engaging portions at both ends and a central portion between both ends of the rod-shaped body. The outer peripheral portion is composed of a tubular body made of a flexible layer.

  In this case, it is easy to firmly hold the rod body so as to apply a large force to the keren blade.

  In the Keren tool assembly of the present invention, typically, the rigid rod-like body of the rod body has a male thread portion formed over its entire length.

  In this case, the rigid rod-shaped body of the rod body is easily firmly fixed to the tubular body of the rod body. In addition, threading of the male thread portion is facilitated.

  In the Keren tool assembly of the present invention, typically, the engaging portion of the Keren tool body mounting portion of the rod body is composed of a male screw portion, and the complementary engaging portion of the Kelen tool body mounting portion of the Keren tool body is female. It consists of a screw part.

  In this case, it is easy to attach and detach. However, if desired, other mutual engagement means may be used instead of screwing.

  In the Keren tool assembly of the present invention, typically, the Keren tool body main body of the Keren tool body and the Keren tool body support in which the Keren tool body main body is attached in an eccentric state in the thickness direction. An inclined shoulder is formed at a corner formed by the tip of the shaft.

  In this case, since a thumb can be put on the shoulder of the side of the keren tool body on which the keren work is not performed, a large force can be easily applied during the keren work. In addition, combined with the characteristics of the grip portion, it is easy to continue the cleansing work without fatigue for a long period of time.

  In the Keren tool assembly of the present invention, typically, the Keren tool body support shaft portion and rubber formed around the connection portion between the Keren tool body support shaft portion and the Keren tool body body portion. Having a paint coating layer. In this case, it is easy to stably hold the keren tool assembly, so that a large force can be easily applied during the keren work, and the keren work can be easily continued without fatigue for a long period of time. When there is a shoulder, naturally, the surface of the shoulder is also covered with a rubber-based paint. However, depending on the case, it may be coated with another paint or the like, or may not be coated.

  A preferred embodiment of the present invention will be described based on a preferred embodiment shown in the accompanying drawings.

  As shown in FIGS. 1A and 1B, a kelen tool assembly 1 according to a preferred embodiment of the present invention includes a rod body or handle 3 and a pair of keren tool bodies 5A and 5B (both of them). When not distinguishing or generically, it is represented by reference numeral 5). The Keren tool assembly 1 has one advantage of ease of use by humans, such as ease of application of force and ease of holding by the user. The dimension etc. which are are described as one specific example. However, these dimensions and the like (numerical values) are a preferred example, and are not intended to limit the characteristics of the present invention by these dimensions. As long as each of them can play a predetermined role, each dimension may be larger. It may be smaller and may have a different size relationship or ratio.

  Here, in a broad sense, the Keren tool body is not only a welded flying object in which the droplet-like molten flying object generated during welding adheres to the surface of the object to be welded and solidifies, but also during painting. Including spray paints that are formed by the sprayed paint adhering to the surface of the object to be coated in the form of droplets and solidifying, or those that scrape off deposits on the concrete surface, adhesive on the surface of the article, iron rust on the steel surface, etc. . However, the kelen tool body here preferably refers to an element having a cutting edge made of cemented carbide as the kelen blade at the tip.

  The rod body 3 includes a rigid rod-like body 10 and a tubular body 20 as can be seen from FIGS. 2 (a), (b), (c) and (d).

  As can be seen from (c) of FIG. 2, the rigid rod-shaped body 10 includes a male screw 11 on the outer periphery over the entire length. However, as long as male screw portions are formed at both end portions 12 and 13 protruding from the tubular body 20 and the rigid rod-like body 10 can be sufficiently firmly fixed to the tubular body 20, the central portion 14 hidden inside the tubular body 20. The male screw part does not need to be formed. The rigid rod-like body 10 has, for example, a length of about 14 cm and a diameter of about 1.3 cm (1/2 inch), and the tubular body 20 has a length of about 10 cm and an outer diameter of about 2.3 cm. . Therefore, the protruding screw portions 12 and 13 at both ends are each about 2 cm in length.

  The tubular body 20 is fitted and fixed to the rigid rod-like body 10 so as to cover the intermediate portion 14 other than the both-end screw portions 12 and 13 of the rigid rod-like body 10.

  The tubular body 20 has an inner tubular layer, that is, an inner tubular portion or an inner sheath portion 22 made of a resin tube having a relatively high rigidity, and has a higher flexibility than the inner tubular portion 22 and is somewhat soft when a person grasps it by hand. Or it has the outer tubular layer which consists of a soft resin tube of the extent which feels a softness | flexibility, ie, the outer tubular part thru | or the outer sheath part 24. The outer diameter of the inner tubular portion 22 is about 1.8 cm. The outer tubular portion 24 has an outer diameter of about 2.3 cm and a thickness of about 0.5 mm.

  The inner tubular portion 22 is made of, for example, a pipe made of vinyl chloride suitable for use as a pipe such as a water pipe or a wiring insertion pipe. However, it may be made of other materials as long as it is sufficiently higher in rigidity than the outer tubular portion 24 and is resistant to water, oil, etc. and can withstand in a normal use environment.

  On the other hand, the outer tubular portion 24 is made of, for example, a material such as synthetic rubber or a composite material that is usually suitable for use as a pressure-resistant rubber hose. However, as long as it is softer than the inner tubular portion 22 and feels soft when touched by hand, it is resistant to water, oil, etc. It may be made.

  The outer tubular portion 24 is integrally fixed to the inner tubular portion 22. This integral fixation can be achieved simply by forcing the inner tubular portion 22 into the outer tubular portion 24 so that the outer tubular portion 24 is somewhat expanded (expanded in diameter). It may be realized by being fixed to each other by means.

  The inner tubular portion 22 of the tubular body 20 and the portion of the rigid rod-shaped body 10 fitted into the inner tubular portion 22, that is, the middle or central portion 14 are fixed to each other with an adhesive. If desired, for example, a female screw is formed in the inner tubular portion 22, and the rigid rod-like body 10 in the form of a male screw is screwed into the inner tubular portion 22 so that the two are actually fixed to each other. Also good. Even then, they may be secured together by an adhesive or other auxiliary mechanical locking means.

  The outer peripheral surface 25 of the tubular body 20 is typically cylindrical. However, if desired, it may be a polygonal cylinder or may have a different shape depending on the portion in the longitudinal direction.

  As shown in FIGS. 3 (a) and 3 (b), FIG. 4 (a) and (b), and FIG. 5 (a) and (b), It has a main body part 30, a keren tool body support shaft part 40, and a connecting shoulder part 70.

  The Keren tool body main body 30 has, for example, the same shape and structure as the tip of a conventional Keren rod, and is a thick plate as a whole. 32. The Keren blade support part 32 has a uniform thickness as a whole and is slightly thinner than the Keren blade 31. However, conversely, it may be a little thicker or practically the same thickness.

  There are various types of the keren tool body 5 depending on the width of the kelen tool body body 30, that is, the length of the kelen blade 31. In the example shown in FIGS. 1A and 1B, the keren tool body 5A is wide and the length of the kelen blade 31A is long, and the kelen tool body 5B is narrow and the length of the kelen blade 31B is long. Is short. If desired, the length of the keren tool body body 30 may be different.

  For example, as can be seen from FIG. 3A, the plate-shaped kelen blade 31 as a whole has parallel main surfaces 31a and 31b, and the plate-like kelen blade support portion 32 as a whole also has parallel main surfaces 32a and 32b. Have The main surfaces 31a and 32a are actually flush with each other, and the major surfaces 31b and 32b are almost flush with each other although there are slight steps due to the difference in thickness. The keren blade 31 and the kelen blade support portion 32 may be the same thickness or the kelen blade support portion 32 may be slightly thicker than the kelen blade 31.

  For example, as can be seen from FIG. 3B, the keren blade 31 includes a rectangular plate-shaped base portion 33 having a uniform thickness, and a cutting edge portion 35 formed on the tip 34 side of the base portion 33 and becoming thinner toward the tip. Have

  The keren blade support portion 32 includes a rectangular plate-like base main body portion 36 having the same width as the base portion 33 of the kelen blade 31 and a plate-like base connecting portion 37 coupled to the kelen tool body support shaft portion 40. Have. More specifically, as can be seen from FIG. 3B, the base connecting portion 37 is smoothly curved and narrowed at the distal end side bending portion 37a, and is bent backward at the proximal end side bending portion 37b. is doing. The end of the base connecting portion 37 is, for example, a base end 38 that is thin and has a substantially constant width. In addition, the base end 38 may be so wide that it approaches a junction part with the Keren tool body support shaft part 40.

  As can be seen from FIGS. 5A and 5B, the Keren tool body support shaft portion 40 includes a shaft portion main body portion 41 and a shaft portion covering main body portion 42 made of a flexible material such as rubber.

  In this example, the shaft main body 41 is in the form of a hexagonal nut, the outer peripheral surface 43 is a hexagonal cylinder, and a circular through hole 44 is provided in the center, and a female screw 45 is formed in the hole 44. ing. The female screw 45 has a shape and a size that are just screwed with the male screw 11 of the rigid rod-shaped body 10 of the rod body 3. The shaft main body 41 has, for example, a regular hexagonal cross section with a length of about 3 cm and a maximum diameter of about 2.3 cm, and a screw hole with an inner diameter of about 1.3 cm (1/2 inch). ing.

  In the elongated rectangular region 48 along one side 47 of the hexagon of one end surface 46 of the shaft main body 41, the base end 38 of the base main body 36 of the kelen blade support 32 in the kelen tool body main body 30 is provided. Are actually in contact with each other at the elongated rectangular end surface 38a and fixed by welding. Accordingly, the keren tool body body 30 is eccentric in the thickness direction of the kelen tool body body 30 with respect to the central axis C of the kelen tool body support shaft 40 or the shaft body 41.

  In this example, the outer peripheral surface 43 of the shaft body 41 is a hexagonal cylinder, but may be a cylindrical or other shape instead of the hexagonal cylinder as long as the finger can be gripped as described below. .

  The shaft portion covering main body portion 42 of the keren tool body support shaft portion 40 includes a tubular covering portion 51 in the form of a tube and an annular covering portion 52 in the form of an annular flange portion. The annular covering portion 52 is integrally connected to the tubular covering portion 51 at the proximal end 53 of the tubular covering portion 51. The cylindrical covering portion 51 includes a distal-side large-diameter protruding portion 56 at the distal end 55 of the outer periphery 54, and a proximal-side large-diameter protruding portion 57 at the proximal end 53 of the outer periphery 54. Therefore, a region between the large diameter portions 56 and 57 is a relatively small diameter portion 58. The large diameter portions 56 and 57 of the shaft portion covering main body 42 have widths (axial lengths) of about 0.5 to 0.7 cm and about 0.3 to 0.5 cm, respectively. The width (axial length) is about 2 cm. The outer diameter of the small-diameter portion 58 that is an intermediate portion is about 2.5 cm, and the outer diameters of the large-diameter portions 56 and 57 are about 5 mm larger than the outer diameter of the small-diameter portion 58. Preferably, the outer diameter of the intermediate small diameter portion 58 of the keren tool body support shaft portion 40 is larger than the outer diameter of the rod body 3. However, if desired, it may be the same or smaller in some cases.

  The shaft portion covering main body portion 42 of the keren tool body support shaft portion 40 is fitted to the hexagonal cylindrical outer peripheral surface 43 of the shaft portion main body portion 41 by the cylindrical covering portion 51, and the shaft portion main body portion 41 is formed by the annular covering portion 52. It is closely attached to the base-side end surface 49 of the.

  The tip-side large-diameter protruding portion 56 of the shaft portion covering main body portion 42 of the keren tool body supporting shaft portion 40 has an outer surface on the same side as one main surface from which the kelen tool body main body portion 30 is eccentric. The portion 56a is cut out so as to be substantially parallel to the main surface. That is, in FIG. 3A and FIG. 5A, the region indicated by the imaginary line 56i is notched.

  The annular covering portion 52 of the shaft portion covering main body portion 42 of the keren tool body supporting shaft portion 40 has a hole 59 that is substantially the same as the hole 44 of the shaft portion main body portion 41 of the kelen tool body supporting shaft portion 40. In the illustrated example, the hole 59 is practically the same size as the hole 44, but the diameter of the hole 59 may be larger than the diameter of the hole 44. In some cases, the annular covering portion 52 may not be provided (in other words, the diameter of the hole 59 may match the inner diameter of the cylindrical covering portion 51).

  A shoulder portion 70 is formed in a corner region 71 formed by the end surface 46 of the shaft portion main body portion 41 of the keren tool support shaft portion 40 and the main surface 32a of the kelen blade support portion 32 of the kelen tool body main body portion 30. Has been.

  In this example, the shoulder 70 fills the corner 71 formed by the end surface 46 of the shaft main body 41 and the main surface 32 a of the kelen blade support 32 and closes the hole 44 of the shaft main body 41. Further, it is made by repeatedly forming a build-up 72 by arc welding. As a result, the shoulder portion 70 enables, on the one hand, strong joining or mutual fixation by welding between the shaft portion main body portion 41 of the Keren tool support shaft portion 40 and the Keren tool base body portion 30, and on the other hand, The end of the end face 46 side (front end side) of 44 is closed, and it becomes possible to put a thumb on as described later. Actually, for example, in FIG. 5 (b), the convex and concave portions on the surface of the built-up formed in multiple stages as indicated by the broken line 72i are removed by, for example, G finishing (finishing by a grinder) or other means. And processed into a shape suitable for placing a finger.

  It should be noted that the weld overlay 72 slightly enters the hole 44 as indicated by an imaginary line 77 in FIG. However, the length of the hole 44 is compared with the length of the ends 12, 13 of the rod body 3 provided with the male screw portion 11 to be screwed into the female screw portion 45 of the hole 44. Since the length of the hole 44 is about 3 cm and the length of the end portions 12 and 13 for attaching the kelen tool body is about 1.2 to 1.4 cm in this example, the weld overlay 72 Even if the back side portion 77 enters the hole 44 to some extent, the entire length of the end portions 12 and 13 for attaching the kelen tool body of the rod body 3 is equal to that of the kelen tool body support shaft portion 40 of the kelen tool bodies 5 and 5. It can be screwed into the hole 44.

  In addition, the shaft part main body part 41 of the keren tool support shaft part 40 and the kelen blade support part 32 of the kelen tool body main body part 30 are connected to the kelen tool support shaft part 40 and the kelen tool body main body part 30 during the keren operation. In the case where the mutual contact surfaces 48, 38a and the peripheral regions of the corresponding contact surfaces 48, 38a are joined or fixed to each other by welding or the like sufficiently firmly to withstand the stress and impact received by the connecting portion with Instead of forming the shoulder portion 70 by overlaying, G finishing, or the like, the shoulder portion 70 may be formed by arranging and fixing a member previously formed in the shape of the shoulder portion 70 at a position where the shoulder portion 70 is located. . In this case, the shoulder 70 may be steel or other metal, resin, ceramic or other nonmetal as long as it can be fixed.

  Typically, the shoulder 70 is inclined so as to be closer to the main surface 32a of the keren blade support part 32 as it is away from the end face 46 of the shaft part main body 41, and is supported as it is away from both sides in the width direction from the center in the width direction. It has a shape that is inclined so as to approach the main surface 32 a of the portion 32. Therefore, the shoulder 70 has an inclined surface 73 roughly in the center in the width direction. When the width of the inclined surface 73 is relatively small, slopes 74 and 75 falling in the width direction may be provided on both sides of the inclined surface 73.

  The Keren tool element body 5 includes the entire outer surface of the shoulder part 70, the entire outer surface of the Keren tool support shaft part 40 (excluding the part where the shoulder part 70 overlaps), and the Keren tool element body main part. The entire outer surface of the portion other than the region adjacent to the kelen blade 31 (excluding the portion where the shoulder portion 70 overlaps) of the 30 kelen blade support portions 32 is covered with a rubber-based coating layer or coating layer 60. It has been broken. As the rubber-based clothing layer 60, for example, a gripping portion of a tool is coated to form an elastic rubber film, which blocks air and water, and is known as a liquid rubber dipping paint that works as a cushioning material. Things are used. However, in order to give priority to the explicit indication of the members under the coating layer or coating layer 60, the rubber-based coating layer or coating layer 60 is shown in phantom lines in the sectional views of FIGS. 3A and 3B, only the boundary of the region adjacent to the keren blade 31 in the kelen blade support portion 32 is indicated by reference numeral 60. On the other hand, in the drawings other than (a) and (b) in FIG. 5 and (a) and (b) in FIG. 3, priority is given to the explicit relationship between the other elements, and the coating layer 60 that covers various elements is provided. Shown omitted.

  Regarding kelen work using the kelen tool assembly 1 configured as described above, when the molten metal droplets scattered during welding are solidified on the surface of the steel plate and fixed to the surface, the solidified and fixed metal is removed. Will be described in more detail below.

  First, in accordance with the kelen work to be performed, kelen tool bodies 5A and 5B having kelen blades 31A and 31B having desired widths are screwed onto the projecting male screw portions 12 and 13 projecting at both ends of the rod body 3. Thereby, the kelen tool bodies 5A and 5B at both ends are fixed in a direction in which the main surfaces 32a and 32a are substantially parallel to each other, as shown in FIGS. In order to secure the parallelism in this direction to a predetermined level or more, each keren tool body 5A, 5B is fixed to the rod body 3 with a pin or the like at a predetermined angular position. Good.

  Next, the keren tool assembly 1 is grasped by hand. In the following, the tool body that is used for the current keren work is indicated by reference numeral 5A, and the tool element that is not used for the current keren work is indicated by reference numeral 5B.

  When grasping with the right hand 90, the state as shown in FIG. 6 as a whole and as shown in FIG. 7 as an enlarged view of the gripping portion viewed from the palm side is adopted. That is, among the keren tool bodies 5A and 5B, the proximal end portion of the kelen tool body support shaft portion 40B and the kelen tool body body portion 30B (the kelen tool body body portion 30B) of the tool body 5B which is not used for the current kelen work. The blade support portion 32 </ b> B and the vicinity of the tool body 5 </ b> B of the rod body 3 are gripped by the right hand 90 along the palm 91 so as to cross the palm 91 of the right hand 90.

  At this time, the index finger 92 is disposed along the relatively small diameter portion 58B sandwiched between the large diameter portions 56B and 57B of the both ends of the Keren tool body support shaft portion 40B, and the middle finger 93 is disposed on the index finger 92 side. The edge is disposed along the outer periphery of the tubular body 20 of the rod body 3 along the proximal side edge (the side on the outer surface of the annular covering portion 52) of the large diameter portion 57B of the keren tool body support shaft portion 40B. The The ring finger 94 and the little finger 95 are arranged so as to surround the tubular body 20 of the rod body 3 at adjacent positions. On the other hand, the thumb 96 has a portion 97 between the first joint and the second joint at the palm-side surface portion 97a of the end surface 48B of the Keren tool body support shaft portion 40B and one of the shoulder portions 70B on the end surface 48B. The side edge 97b of the portion 97 on the index finger 92 side is disposed so as to follow the inclined portions 73B, 74B, and 75B of the shoulder portion 70B. Of the thumb 96, the portion 98 on the tip side from the first joint mainly extends along the inclined portion 74B on the back side of the shoulder 70B, and most of the portion 98 protrudes from the large-diameter portion 56B. The part 56B holds the Keren tool body support shaft part 40B.

  In this way of gripping, not only can the gripper tool assembly 1 be gripped with a significantly greater force than when gripping a portion having a constant diameter, but also the cracker on the tip side of the paddle tool assembly 1 A large force F1, F2 direction in the direction along the surface Q and in the extending direction of the rod body 3 is exerted on the tool body 5A, so that the molten material is solidified (solidified) on the surface Q of the keren work object P such as a steel plate. ) The object R can be effectively peeled off or scraped off from the surface Q by the cutting edge 35A of the Keren blade 31A of the Keren tool body main body 30A of the Keren tool body 5A. Note that the notch portion 56a of the large-diameter portion 56 also makes it possible to grip more strongly and stably for a long period of time.

  At this time, the outer tubular portion 24 made of a relatively soft material of the tubular body 20 of the rod body 3 and the rubber-based coating layer (coating layer) 60 of the tool body 5B provide a firm grip feeling and gripping force by the hand 90. And a large keren working force F1, F2 can be applied.

  As described above, in this kelen tool assembly 1, the kelen tool bodies 5A and 5B are detachably attached to both ends, so that two kelen tool bodies 5A and 5B having a desired size and shape are attached. Thus, the tool assembly 1 is prepared. Therefore, for example, without carrying around two keren rods, the kelen work using two types of kelen tool bodies can be performed.

  Further, in the state where the support shaft portion 40 of the keren tool body 5 is formed to have a relatively large diameter and the kelen tool body body portion 30 is eccentric with respect to the support shaft portion 40 in the thickness direction of the body portion 30. Since it is fixed, a corner 71 is formed where the end surface 48 of the Keren tool body support shaft 40 and the main surface 32a of the Keren tool body body 30 face each other, and a thumb 96 is disposed along the corner 71. Therefore, large scraping forces F1 and F2 can be exerted during the keren operation. The presence of the shoulder portion 70 allows the gripping with the thumb 96 and the input of force to be performed more reliably, so that a large scraping force F1, F2 can be exerted during the cleansing operation. Further, since the support shaft portion 40 of the keren tool base body 5 is formed to have a relatively large diameter, the tool assembly 1 can be firmly held by turning the index finger 92 to the support shaft portion 40. At this time, a large scraping force F1, F2 can be exerted. Furthermore, since the large-diameter portions 56 and 57 are formed at both ends of the support shaft portion 40, the index finger 92 can be stably disposed on the relative small-diameter portion 58 between the large-diameter portions 56 and 57. A large scraping force F1, F2 can be exerted during the work. Note that the cutout portion 56a of the large-diameter portion 56 makes it possible to grip more firmly and stably for a long period of time.

  Here, since the support shaft portion 40 of the Keren tool base body 5 has a relatively large diameter, (1) screw engagement (removable engagement) with the end screw portions 12 and 13 of the rod body 3 is achieved. Besides, (2) the eccentric tool body 30 can be fixed in an eccentric manner to facilitate scraping, and (3) large scraping by hooking the thumb 96 on the corner 71. Further, it is possible to apply force, and (4) a strong grip with the index finger 92 is enabled. That is, in this kelen tool assembly 1, not only the two keren tool bodies 5 and 5 are detachably attached to both ends, but also the kelen tool body 5B attached to the base end of the rod body 3. It is possible to perform the cleansing work with the leading edge side clean tool body 5A with a strong force.
