Description

Technical Field

[0001] This disclosure relates to a tool and a binding machine. Prior Technology

[0002] Tools such as rebar tying machines, nailing machines, and screw fastening machines are equipped with hooks on the tool body or handle. These hooks are used to suspend the tools from the worker's belt when not using the tools or when holding and carrying them. When not using the tools, they are used to suspend the tools from scaffolding or ladders placed on site.

[0003] For example, Patent Document 1 describes a screw fastening machine with a pair of upper and lower insertion holes formed by openings on the side of the head, and a hook device installed in the insertion holes. Also, Patent Document 2 describes a tool for driving in a hook by fixing a hook support member to the rear of a handle formed at one end of the main body, and installing a hook on the hook support member to connect the hanging part and the sliding shaft part in a bent shape.

[0004] Incidentally, in situations such as reinforcing walls or columns, or bundling already reinforced steel bars with wire, where reinforcement and bundling are performed interchangeably, the tools (steel bundling machine) are often hung on the worker's belt or placed on scaffolding during reinforcement work. However, compared to hanging the tools on the belt or placing them on scaffolding, suspending them from the already reinforced steel bars allows for a smoother transition to the next task (bundling), which is more efficient. [Preliminary Technology Documents] [Patent Literature]

[0005] [Patent Document 1] Japanese Invention Patent Publication No. 2006-150503 [Patent Document 2] Japanese Patent No. 4877488 Summary of the Invention

[0006] [The problem the invention aims to solve]

[0007] However, as with the tool disclosed in Patent Document 1, when the hook is installed on the side of the body with the opening of the hook facing forward, and the tool is hung on a steel bar or the like with the hook opening aligned with it and then released, the tool tilts significantly and becomes unstable, making it easy for the tool to fall off the steel bar. Furthermore, because the tool tilts significantly when released, it is easy for it to come into contact with surrounding steel bars, potentially damaging the surrounding steel bars or the tool itself.

[0008] Furthermore, in the tool disclosed in Patent Document 2, because the hook is located on the lower side of the grip, when hanging the hook on a steel bar or ladder, the operator must rotate their wrist while hanging, which makes hanging difficult and also makes it difficult to quickly move on to the next task.

[0009] The present invention aims to solve the above-mentioned problems by providing a tool and a binding machine that can easily suspend components such as reinforcing bars at the work site and does not tilt significantly during suspension. [Methods used to solve problems]

[0010] The tool system disclosed herein includes a body, a grip, a first hook mounting part, and a second hook mounting part. In the aforementioned body part system, an output part is provided at the front end along the long side, and a drive part that drives the output part is housed inside. The aforementioned grip part system is provided on the lower side of the aforementioned body part. The aforementioned first hook mounting part system is located on the upper side of the aforementioned body part and can mount a hook with one opening. The aforementioned second hook mounting part system is located on the side side of the aforementioned body part and can mount the aforementioned hook. In the aforementioned first hook mounting part system, the hook is mounted with its opening facing the front side along the long side of the aforementioned body part. In the aforementioned second hook mounting part system, the hook is mounted with its opening facing the lower side along the vertical direction of the aforementioned body part.

[0011] The first bundling machine system disclosed herein includes a main body, a receiving part, a gripping part, and a hook mounting part. In the aforementioned main body system, the bundling part for bundling wire is provided at the front end along its long side, and a drive unit that drives the bundling part is housed inside. The aforementioned receiving part system is provided on the lower side of the aforementioned main body system, and can feedably receive the aforementioned wire. The aforementioned gripping part system is located on the lower side of the aforementioned main body system, behind the aforementioned receiving part. The aforementioned hook mounting part system is located on the upper side of the aforementioned main body system, and a hook with one opening can be mounted. The aforementioned hook mounting part system mounts the hook such that the opening of the hook faces the front side along the long side of the aforementioned main body system.

[0012] The second bundling machine system disclosed herein includes a main body, a receiving part, and a gripping part. The main body has a bundling part for bundling wires located at the front end along its long side, housing a drive unit that drives the bundling part. The receiving part is located on the underside of the main body and feedably receives the wires. The gripping part is located on the underside of the main body, behind the receiving part. The bundling machine further includes a hook mounting part. The hook mounting part is located on the side of the main body and can mount a hook with one opening. The hook mounting part mounts the hook with the opening facing the center of gravity of the bundling machine.

[0013] The third bundling machine system disclosed herein comprises a main body, a receiving part, a gripping part, and a hook mounting part. The main body has a bundling part for bundling wire located at the front end along its long side, housing a drive unit that drives the bundling part. The receiving part is located at the rear end along the long side of the main body, feedingly housing the wire. The gripping part is located on the lower side of the main body. The hook mounting part is located on the upper side of the main body, and a hook with one opening can be mounted thereon. The hook is mounted with its opening facing the front side along the long side of the main body. [Effects of the invention]

[0014] According to the tool disclosed herein, the first hook mounting part is installed with the hook on the upper side of the main body and the hook opening facing forward. Therefore, when the hook installed on the first hook mounting part is used to suspend a steel bar, wall, column, or other suspended component located in front of the operator, the suspension can be performed with minimal wrist movement while tilting the front end of the main body with the output part downward. Thus, work efficiency is improved when repeating the use of the tool and the suspension movements when not in use, and the operator's workload is also reduced. Furthermore, the second hook mounting system is installed with the hook on the side of the main body and the hook opening facing downwards. Therefore, when the tool is suspended from a steel bar or wall, the long side of the main body is kept approximately parallel to the steel bar or wall. As a result, the amount of protrusion of the main body is reduced when suspending the tool, and the operation is not hindered even when suspending the tool, allowing for smooth movement and operation at the work site. Therefore, since the first hook mounting part and the second hook mounting part, which have the above-mentioned effects, are set on the same tool, it is possible to improve work efficiency and reduce the burden on operators in various work sites and under various conditions.

[0015] The first cable bundling machine disclosed herein has a cable receiving section and a gripping section on the lower side of the main body, so the center of gravity of the cable bundling machine is below the main body, or more specifically, near the receiving section. Therefore, when such a cable bundling machine is suspended to a member such as a reinforcing bar via a hook installed on the hook mounting section, due to the aforementioned center of gravity position, the cable bundling machine will not tilt significantly and become unstable, and can be held stably. In other words, because the cable bundling machine is stably suspended to the member being suspended, problems such as the cable bundling machine falling off the reinforcing bar are unlikely to occur. Furthermore, since the hook mounting section is installed with the hook on the upper side of the main body and the opening of the hook facing forward, when the hook is installed on the hook mounting section, after the cable bundling operation on the reinforcing bar located in front of the operator, the reinforcing bar (the member being suspended) can be suspended with minimal wrist movement while tilting the front end of the main body with the cable bundling section downward. Therefore, with the repeated use of the bundling machine and the hanging action when not in use, the work efficiency is improved, and the workload of the operators can also be reduced.

[0016] According to the second bundling machine disclosed herein, because it has a wire-receiving section and a gripping section on the lower side of the main body, the center of gravity of the bundling machine is below the main body, more specifically, near the receiving section. Therefore, when such a bundling machine is suspended from a member such as a reinforcing bar via a hook mounted on the hook mounting section, due to the aforementioned center of gravity position, the bundling machine will not tilt significantly and become unstable, and can be held stably. In other words, because the bundling machine is stably suspended from the member, problems such as the bundling machine falling from the reinforcing bar are unlikely to occur. Furthermore, since the hook mounting section is installed with the hook on the side of the main body and the opening of the hook facing downwards, when the bundling machine is suspended from a member such as a reinforcing bar or a wall, the long side of the main body is kept approximately parallel to the reinforcing bar or wall. Therefore, the amount of protrusion of the main body is reduced for the member being suspended, and even when the bundling machine is suspended, it will not hinder the operation, allowing for smooth movement or operation at the work site.

[0017] According to the third bundling machine disclosed herein, the hook mounting part is installed with the hook on the upper side of the main body and the hook opening facing forward. Therefore, when the hook is installed in the hook mounting part, after bundling the reinforcing bars located in front of the operator, the reinforcing bars (the suspended components) can be suspended with minimal wrist movement while tilting the front end of the main body with the bundling part downward. Thus, work efficiency is improved when repeating the use of the bundling machine and the suspension operations when not in use, and the operator's workload is also reduced.

[0019] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0020] <First Embodiment> [Structure Example of Rebar Bundling Machine 1A]

[0021] Figure 1 is a perspective view taken from the rear left side of the rebar bundling machine 1A according to the first embodiment; Figure 2 is an exploded perspective view taken from the front left side of the rebar bundling machine 1A; Figure 3 is a left side view of the rebar bundling machine 1A according to the first embodiment; Figure 4 is a view with a portion of the rebar bundling machine 1A covered but not shown; Figure 5 is a front view of the rebar bundling machine 1A according to the first embodiment. Furthermore, the rebar bundling machine 1A is an example of a tool or bundling machine, and in this specification, the rebar bundling machine 1A is sometimes referred to as a tool or bundling machine.

[0022] The rebar bundling machine 1A series includes a main body 10 constructed from a generally rectangular shell. A bundling section (output section) 4 is located at one end (front end) of the main body 10 along its long side, and a drive section 8 for driving the bundling section 4 is housed inside the main body 10. Furthermore, the rebar bundling machine 1A series includes a cartridge (receiving section) 2 that feeds and receives wire W at one end of the main body 10 along its short side (orthogonal to the long side), i.e., at the lower 10e side of the main body 10, and a gripping section 11 located at the lower 10e side of the main body 10, behind the cartridge 2 (in the aforementioned long side direction). The bundling section 4 has a coiling forming section 5 protruding from the front end of the main body 10 and applying a bending curl to the wire W fed from the cartridge 2, and a twisting section 7 that twists the wire W that has been bent by the coiling forming section 5.

[0023] The rebar bundling machine 1A series includes a first hook mounting part 210 located on the upper 10a side of the main body 10 (opposite to the aforementioned lower 10e side via the main body 10), on which a U-shaped hook 200A with one side opening can be mounted, and a second hook mounting part 310 located on the left side 10b side of the main body 10, on which a hook 300 can be mounted. Furthermore, in this embodiment, the upper 10a side refers to the area excluding the upper 10a of the main body 10, and includes the area near the boundary between the upper 10a of the main body 10 and the left side 10b, right side 10c, or rear end face.

[0024] The rebar bundling machine 1A series includes a cover 250 that is provided along the front-rear direction (long side direction) to cover at least a portion of the upper part 10a of the main body 10. The cover 250 series includes a guiding surface 250a for guiding the rebar (suspended member) S to the opening 201 of the first hook 200A when the first hook 200A, which has been installed on the first hook mounting part 210a, etc., is suspending the rebar (suspended member) S.

[0025] As shown in Figures 1 to 5, the housing 2 is located in front of the main body 10 and extends downward from the bottom 10e of the main body 10. Inside the housing 2, a spool that can be rotatably and detachably stored and unwound a long, coiled wire W is mounted. The wire W can be made of deformable metal wire, or it can be made of metal wire coated with resin or stranded wire.

[0026] The gripping part 11, which is the part that the operator holds during operation or handling, is located on the lower 10e side of the main body 10. The gripping part 11 is positioned behind the housing 2, facing it, and extends downwards from the lower 10e of the main body 10. At the front base of the gripping part 11, a trigger 12 is provided for the operator to open and close the binding action. Furthermore, the binding action execution system can also be combined with the activation of the contact switch 9 located at the top of the main body 10. The gripping part 11 has a battery mounting section at its lower top for detachable installation of the battery 15.

[0027] As shown in Figures 1 and 2, the cover portion 250 is constructed of a slender flat plate member with a roughly U-shaped cross-section that extends in the front-rear direction, covering the upper part 10a of the main body portion 10. The upper side of the cover portion 250 forms a guide surface 250a for slidably guiding the reinforcing bar S from the front of the main body portion 10 towards the opening 201 of the first hook 200A. At the front end side of the cover portion 250, an inclined surface 250b is provided, continuous with the guide surface 250a and gradually increasing in elevation from the front to the rear. The inclined surface 250b is used to guide the reinforcing bar S into the opening 201 of the first hook 200A when the first hook 200A is used to suspend the reinforcing bar S.

[0028] The cover portion 250 has a left side portion 250c and a right side portion 250d that are erected downwards from both ends in the left-right direction of the guide surface 250a. The front sides of the left side portion 250c and the right side portion 250d of the cover portion 250, and the rear sides of the left side portion 250c and the right side portion 250d of the cover portion 250 are respectively mounted to the left side surface 10b and the right side surface 10c of the main body portion 10 by means of fastening means 600 such as bolts and nuts.

[0029] As shown in Figures 1 and 2, the cover portion 250 has a plurality of first hook mounting portions 210a, 210b, 210c, 210d, and 210e extending from the front side of the guide surface 250a toward the rear side. By providing a plurality of first hook mounting portions 210a, the mounting position of the first hook 200A can be selected or changed according to the usage environment or operator preferences. Furthermore, in this embodiment, the first hook mounting portions 210a, etc., are provided on the guide surface 250a of the cover portion 250, but the first hook mounting portions 210a, etc., can also be provided directly on the body portion 10. Also, although the first hook mounting portions 210a, etc., are provided in five locations, the number of locations is not limited to five.

[0030] The first hook mounting part 210a has a locking hole 212a into which the locking piece 202 of the first hook 200A can be inserted, and screw holes 214a, 214a into which screws 206, 206 are screwed. The first hook mounting part 210d has a locking hole 212d into which the locking piece 202 of the first hook 200A can be inserted, and screw holes 214d, 214d into which screws 206, 206 are screwed. Furthermore, the first hook mounting parts 210b, 210c, and 210e have the same structure as the first hook mounting parts 210a, etc., so detailed descriptions are omitted.

[0031] The first hook 200A series, as shown in Figures 1 to 5, is a component used to suspend the rebar bundling machine 1A onto the rebar S. In this embodiment, it is constructed by a flat plate member whose side shape is bent into a U-shape. In this embodiment, the first hook 200A series forms a slit along its long side and is forked, but is not limited to this shape. Furthermore, the first hook 200A does not necessarily have to be U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped. That is to say, the first hook 200A series only needs to include a suspension part for suspending onto the rebar and a fixing part for fixing to the cover 250 or the main body 10. Hereinafter, the case where the first hook 200A is installed in the first hook mounting part 210d will be described.

[0032] As shown in Figure 2, a locking piece 202 and through holes 204, 204 are provided on the base end side (end side of the first hook mounting portion 210d) of the first hook 200A. The locking piece 202 is formed to protrude from the base end of the first hook 200A toward the body portion 10 and is configured to engage with the locking hole 212d of the first hook mounting portion 210d. The through holes 204, 204 are provided through the first hook mounting portion 210d at positions facing the screw holes 214d, 214d of the first hook mounting portion 210d.

[0033] In this embodiment, the first hook 200A is fixed to the body part 10 (cover part 250) by means of the engaging piece 202 of the first hook 200A being fitted into the engaging hole 212d of the first hook mounting part 210d, and the screws 206, 206 being screwed into the screw holes 214d, 214d of the first hook mounting part 210d via the insertion holes 204, 204. At this time, the first hook 200A is installed in the first hook mounting part 210d by inserting the opening 201 of the reinforcing bar S into the first hook mounting part 210d in a forward-backward direction, as shown in Figure 3, etc.

[0034] The second hook mounting part 310, as shown in Figures 1 to 3, is provided in the hanging part 250e that hangs downward from the left side 250c of the cover part 250. The second hook mounting part 310 has a locking hole 312 for engaging with the locking piece 302 of the second hook 300, and screw holes 314 for engaging with screws 306.

[0035] Furthermore, in this embodiment, the second hook mounting part 310 is provided on the left side 10b of the main body part 10, but it can also be provided on the right side 10c of the main body part 10, and it can also be provided on both the left side 10b and the right side 10c of the main body part 10. Alternatively, the second hook mounting part 310 can be provided directly on the main body part 10 instead of on the cover part 250.

[0036] The second hook 300 is a component used to suspend the rebar bundling machine 1A from the left side 10b onto the rebar S. Similar to the first hook 200A, it is constructed from a flat plate whose side shape is bent into a U-shape. In this embodiment, the second hook 300 forms a slit along its long side and is forked, but is not limited to this shape. Furthermore, like the first hook 200A, the second hook 300 does not necessarily have to be U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0037] As shown in Figures 2 and 5, a locking piece 302 and through holes 304, 304 are provided on the base end side (end side of the second hook mounting portion 310). The locking piece 302 is formed to protrude from the base end of the second hook 300 toward the body portion 10 and is configured to engage with the locking hole 312 of the second hook mounting portion 310. The through holes 304, 304 are provided through the second hook mounting portion 310 at positions facing the screw holes 314, 314.

[0038] In this embodiment, the engaging piece 302 of the second hook 300 is fitted into the engaging hole 312 of the second hook mounting part 310, and the screws 306 are screwed into the screw holes 314 of the second hook mounting part 310 through the insertion holes 304 and 304. The second hook 300 is fixed to the left side 10b (cover 250) of the main body part 10.

[0039] In this case, the second hook mounting part 310, when viewed from the front (front view) of the main body 10, as shown in Figures 3 and 5, mounts the second hook 300 in such a way that the opening 201 of the first hook 200A mounted on the first hook mounting part 210d, etc., is not obstructed. Furthermore, the second hook mounting part 310 mounts the second hook 300 in such a way that the second hook 300 does not protrude from the guide surface 250a of the cover part 250. Moreover, if the cover part 250 is not provided, the second hook mounting part 310 mounts the second hook 300 in such a way that the second hook 300 does not protrude from the top surface 10a of the main body 10. Alternatively, the second hook mounting part 310 may mount the second hook 300 in such a way that the opening 301 of the second hook 300 is located on the lower or obliquely lower side of the main body 10 in the vertical direction, towards the center of gravity C of the rebar binding machine 1A.

[0040] Here, the center of gravity C of the rebar bundling machine 1A is determined by the weight of the main body 10, the coil forming part 5, the housing 2, the gripping part 11, the battery 15, and their arrangement. In this embodiment, the center of gravity C of the rebar bundling machine 1A is determined by the housing 2, which, because it houses the wire W, is heavier than other components (such as the coil forming part 5 and the gripping part 11), and is located in front of the lower part 10e of the main body 10. Therefore, as shown in Figure 3, the space near the housing 2 on the front side of the trigger 12, in other words, is located in the space between the trigger 12 and the upper side of the housing 2. Furthermore, in the rebar bundling machine 1A, the amount of wire W is reduced by using the wire W housed in the housing 2, and consequently, the overall weight of the rebar bundling machine 1A is also reduced. In this case, the center of gravity C of the rebar bundling machine 1A is slightly shifted, but the center of gravity C does not change significantly.

[0041] As shown in Figure 4, the wire feeding unit 3 system includes a pair of feed gears 30 that clamp and feed one or more parallel wires W, and a feed motor (not shown) that drives the feed gears 30. The rotational motion of the feed motor is transmitted through a transmission mechanism, causing the feed gears 30 system to rotate. The wire feeding unit 3 system feeds the wires W clamped between the pair of feed gears 30 along the extension direction of the wires W. In a configuration that feeds multiple wires, such as two wires W, the two wires W are fed side-by-side.

[0042] The coiling forming section 5 includes a coiling guide 50 that applies a bending curvature to the wire W fed by the wire feed section 3, and an induction guide 51 that guides the wire W, which has been bent by the coiling guide 50, to the twisting section 7. The coiling guide 50 and the induction guide 51 of the coiling forming section 5 are provided at the front end of the main body section 10. In the rebar bundling machine 1A, the path of the wire W fed by the wire feed section 3 is restricted by the coiling forming section 5, causing the wire W to be wound around the rebar S.

[0043] As shown in Figure 4, the cutting unit 6 system includes a fixed blade 60, a movable blade 61 that cuts the wire W by cooperating with the fixed blade 60, and a transmission mechanism that transmits the motion of the torsion unit 7 to the movable blade 61. The cutting unit 6 system cuts the wire W by the rotational motion of the movable blade 61 with the fixed blade 60 as the fulcrum.

[0044] The torsion section 7 system includes a wire locking body 70 that is locked by the wire W, and a rotating shaft that actuates the wire locking body 70. The drive section 8 system includes a motor 80 and a reducer 81 that reduces speed and increases torque. The torsion section 7 and the drive section 8 system, the rotating shaft and the motor 80 system are connected via the reducer 81, and the rotating shaft system is driven by the motor 80 via the reducer 81. The wire locking body 70 system includes a sleeve 71 that is rotated in conjunction with the rotating shaft and actuates a first side hook and a second side hook (not shown).

[0045] The wire W fed by the wire feed section 3 is guided to the coiling forming section 5 by the wire locking body 70. Then, the top end of the wire W, which is bent and guided to the twisting section 7 by the coiling forming section 5, is locked in a state without falling off the wire locking body 70. Next, when the wire W is cut by the cutting section 6, the sleeve 71 moves forward, bending the top end of the wire W locked by the wire locking body 70 and the end end of the wire W cut by the cutting section 6 toward the reinforcing bar S.

[0046] After the top and end sides of the wire W are bent toward the steel bar S, when the sleeve 71 moves further forward, the sleeve 71 rotates in conjunction with the rotating shaft and twists the wire W which is locked by the wire locking body 70.

[0047] [Example of using the first hook 200A]

[0048] Figure 6A illustrates an example of the use of the first hook 200A. For instance, after completing the bundling operation (bundling the rebar S with wire W) and removing the coiling part 5 from the front end of the main body 10 from the rebar S, the operator tilts the coiling part 5 downwards so that the upper part 10a of the main body 10 faces the reinforcement surface, i.e., the rebar S. While the guide surface 250a of the cover 250 is along the reinforcement surface, or the guide surface 250a is abutting against the rebar S (allowing the rebar S to slide on the guide surface 250a), the operator moves the rebar bundling machine 1A downwards to suspend the rebar S using the first hook 200A. Therefore, when suspending the rebar S with the first hook 200A, the operator only needs to tilt and move the rebar bundling machine 1A downwards; there is no need to twist the wrist to rotate the rebar bundling machine 1A. This improves work efficiency and reduces the operator's workload.

[0049] [Example of using the second hook 300] Figure 6B illustrates an example of the use of the second hook 300. For instance, after the binding operation is completed, the operator rotates the rebar binding machine 1A so that the left side 10b of the main body 10 is approximately parallel to the reinforcement surface, thereby suspending the second hook 300 on the rebar S. In this way, by suspending the rebar S with the second hook 300, and because the rebar binding machine 1A is kept approximately parallel to the reinforcement surface with the main body 10, the amount of protrusion of the main body 10 of the rebar S can be reduced. Even when the rebar binding machine 1A is suspended on the rebar S, it does not hinder the operation, allowing for smooth movement or operation at the work site.

[0050] [Modified example of the second hook mounting part 310] Furthermore, the second hook mounting part 310 is not limited to the mounting position shown in Figure 1, as long as the second hook 300 is installed on the left side 10b and the right side 10c of the main body part 10, and the opening 301 of the second hook 300 faces the center of gravity C of the rebar bundling machine 1A.

[0051] Figure 7 shows a modified example of the second hook mounting part 310. The rebar bundling machine 1A series, in addition to the aforementioned second hook mounting part 310, also has second hook mounting parts 310A and 310B.

[0052] As shown in Figure 7, the second hook mounting part 310A is installed at an angle on the front side of the left side 10b of the main body 10, with the opening 301 of the second hook 300 facing the center of gravity C of the rebar binding machine 1A. In this case, the second hook mounting part 310A is installed in a way that prevents the second hook 300 from protruding from the top 10a of the main body 10 or the guiding surface 250a of the cover 250, and does not obstruct the opening 210 of the first hook 200A. Furthermore, the second hook 300 can also be installed in the second hook mounting part 310B using the same installation method as the second hook mounting part 310A.

[0053] According to the first embodiment, the first hook mounting part 210a, etc., is installed with the first hook 200A on the upper 10a side of the main body part 10 and the opening 201 of the first hook 200A facing forward. Therefore, when the first hook 200A is installed in the first hook mounting part 210a, etc., after the binding operation of the steel bar S, etc., located in front of the operator, the steel bar S, etc., can be hung with less movement by not rotating the wrist while tilting the front end side of the main body part 10 with the curling part 5 or the twisting part 7 downward. Therefore, when repeating the use of the steel bar binding machine 1A and the hanging operation when not in use, the work efficiency is improved, and the workload of the operator is also reduced.

[0054] Furthermore, because the rebar bundling machine 1A has a housing 2 for holding wire W and a gripping part 11 on the lower 10e side of the main body 10, the center of gravity C of the rebar bundling machine 1A is below the main body 10, more specifically, close to the housing 2. Therefore, when the rebar bundling machine 1A is suspended from the rebar S via the first hook 200A installed on the first hook mounting part 210a, the rebar bundling machine 1A will not tilt (operate) significantly and become unstable, and can be held stably. In other words, because the rebar bundling machine 1A is stably suspended from the rebar S, problems such as the rebar bundling machine 1A falling from the rebar are unlikely to occur.

[0055] Furthermore, the second hook mounting part 310 is installed with the second hook 300 on the left side 10b of the main body 10 and the opening 301 of the second hook 300 facing downwards. Therefore, when the rebar bundling machine 1A is suspended on the rebar S, the left side 10b of the main body 10 is kept approximately parallel to the rebar S in the front-rear direction. As a result, the protrusion of the main body 10 is reduced for the rebar S, and the operation is not hindered even when the rebar bundling machine 1A is suspended, allowing for smooth movement or operation at the work site.

[0056] Therefore, according to the first embodiment, since the first hook mounting part 210a and the second hook mounting part 310, which have the above-mentioned effects, are provided on a rebar bundling machine 1A, it is possible to improve work efficiency and reduce the burden on operators in various situations at various work sites.

[0057] Furthermore, according to the first embodiment, since the second hook 300 is installed in the second hook mounting portion 310 without obscuring the opening 210 of the first hook 200A, and the second hook 300 is installed in the second hook mounting portion 310 without protruding from the top 10a of the main body portion 10 or the guiding surface 250a of the cover portion 250, the second hook 300 can be prevented from becoming an obstacle when the first hook 200A is suspended from the reinforcing bar S.

[0058] Furthermore, according to the first embodiment, since the cover portion 250 and the guiding surface 250a are provided, the reinforcing bar S can be guided while sliding within the opening 201 of the first hook 200A, so the first hook 200A can be easily hung on the reinforcing bar S. Also, since the cover portion 250 is provided, direct contact between the reinforcing bar S and the main body portion 10 can be avoided, thus preventing damage to the main body portion 10.

[0059] <Second Embodiment> The rebar bundling machine 1B of the second embodiment differs from the rebar bundling machine 1A of the first embodiment in that the hook 200B can move and retract toward the rear of the main body 10. Furthermore, for components that have substantially the same function as the rebar bundling machine 1A of the above-described embodiments, repeated descriptions are omitted by using the same reference numerals.

[0060] [Example of the configuration of rebar bundling machine 1B] Figure 8A is a perspective view showing the hook 200B and hook mounting part 410 of the rebar bundling machine 1B, and Figure 8B is a side view showing the hook 200B and hook mounting part 410.

[0061] The rebar bundling machine 1B series, as shown in Figures 8A and 8B, includes a locking plate 700 that locks the hook 200B to the use position P1, and a hook mounting part 410 that supports the hook 200B, which can move from the use position P1 on the upper 10a side of the main body 10 to the retracted position P2 on the rear 10d side. Here, the use position P1 is the position where the hook 200B is located on the upper 10a side of the main body 10, and can be suspended from the rebar S. The retracted position P2 is the position where the hook 200B is located on the rear 10d side of the main body 10, and will not become an obstruction or obstacle during operation or handling.

[0062] As shown in Figure 8A, the locking plate 700 is a flat plate member with a roughly U-shaped cross-section, covering the rear side of the upper part 10a of the cover portion 250. At the rear end of the locking plate 700, push-pressing portions 702 and 702 are provided for locking the hook 200B in the use position P1. As shown in Figure 8B, the push-pressing portions 702 and 702 are configured to protrude (lift) upwards from the plane of the locking plate 700 by at least the thickness of the hook 200B, such that the hook 200B can be inserted into its lower side. Furthermore, in this embodiment, the push-pressing portions 702 and 702 are configured in two locations according to the forked shape of the hook 200B, but this is not a limitation, and can be appropriately modified according to the shape of the hook 200B.

[0063] The locking plate 700 has a left side portion 700a and a right side portion 700b that are erected downwards from both ends in the left-right direction. As shown in Figure 8A, the left side portion 700a and right side portion 700b of the locking plate 700, and the left side portion 250c and right side portion 250d of the cover portion 250 disposed inside them, are respectively inserted through by a first shaft 720 and a second shaft 722 extending in the left-right direction. The openings of the first shaft 720 and the second shaft 722 supporting the cover portion 250 are elongated holes (not shown), and the locking plate 700 is configured to be movable in the front-back direction relative to the cover portion 250.

[0064] The hook mounting part 410, as shown in Figures 8A and 8B, has a flat plate member 412 extending in the left-right direction toward the main body 10, and locking parts 414, 414 erected from both ends of the flat plate member 412 toward the downward direction. Furthermore, since the locking parts 414 are configured to be common to both sides, only one side will be described below for convenience.

[0065] At the upper center of the flat plate member 412, the folded-back portion 208 of the hook 200B is mounted by a fastener 420. The folded-back portion 208 is a part that extends from the base end of the hook 200B toward the curved portion on the opposite side. The hook 200B is configured to rotate about the axis of the fastener 420, thereby changing the orientation of the hook 200B.

[0066] The locking part 414, as shown in Figure 8B, is approximately circular in top view and is located inside the left side portion 250c of the cover 250. A third shaft 724 is inserted through both the locking part 414 and the left side portion 250c of the cover 250. The opening 414c of the third shaft 724 supporting the locking part 414 is an elongated hole, and the third shaft 724 is configured to be movable in the front-rear direction relative to the locking part 414.

[0067] As shown in Figure 8A, a tension spring 726 is provided between the second shaft 722 and the third shaft 724. One end of the tension spring 726 is mounted on the second shaft 722, and the other end is mounted on the third shaft 724. Therefore, each of the second shaft 722 and the third shaft 724 is biased in opposite directions by the elastic force of the tension spring 726.

[0068] As shown in Figure 8B, a pin 730 protruding inward is provided on the inner surface of the left side portion 250c of the cover portion 250. A first recess 414a and a second recess 414b are formed at a predetermined interval around the periphery of the locking portion 414. The first recess 414a engages with the pin 730 when the hook 200B is in the use position P1, locking the hook 200B in the use position P1. The second recess 414b engages with the pin 730 when the hook 200B is in the retracted position P2, locking the hook 200B in the retracted position P2.

[0069] [Operating example of rebar bundling machine 1B] Next, the operation of the hook 200B when it is moved from the use position P1 on the upper 10a side of the main body 10 to the retracted position P2 on the rear 10d side of the main body 10 will be described. Figures 9A to 9C are operation diagrams of the rebar bundling machine 1B when the hook 200B is moved from the use position P1 to the retracted position P2.

[0070] As shown in Figure 9A, the operator slides the locking plate 700, held by one hand, forward against the cover 250. Simultaneously, the pushing parts 702 move forward and shift from the base of the hook 200B, thus releasing the locking mechanism of the hook 200B.

[0071] Next, the operator holds hook 200B with their other hand and rotates hook 200B backward as shown in Figure 9B. This causes locking part 414 to move backward relative to the third axis 724 through opening 414c, thereby disengaging the first recess 414a of locking part 414 from pin 730, and releasing the engagement between the first recess 414a and pin 730.

[0072] Next, when hook 200B rotates from the working position P1 to the retracted position P2 with the third axis 724 as the fulcrum, the second recess 414b of the locking part 414 is engaged with the pin 730 because the locking part 414 is biased forward by the tension spring 726. In this way, hook 200B is held in the retracted position P2.

[0073] Next, as shown in Figure 9C, the operator rotates hook 200B 180° around the axis of fixing member 420, with the opening 201 of hook 200B facing downwards, causing hook 200B to reverse its position. Hook 200B is biased forward by tension spring 726, and because the folded-back portion 208 of hook 200B contacts the rear end 10d of body portion 10, friction prevents hook 200B from rotating. Through this series of actions, hook 200B can be moved from the operating position P1 to the retracted position P2. Furthermore, by performing the opposite action to the above series of actions, hook 200B can be moved from the retracted position P2 back to the operating position P1.

[0074] As described above, according to the second embodiment, for example, if the hook 200B on the upper 10a of the body part 10 becomes obstructed during bundling operations, the hook 200B can be retracted from the upper 10a of the body part 10 towards the rear 10d side. This improves work efficiency. Furthermore, in the second embodiment, the first hook mounting part 210 is moved towards the rear 10d side, but it can also be configured to move towards the left side 10b side or the right side 10c side. By moving the hook 200B from the upper 10a side of the body part 10 (e.g., towards the left side 10b side), it can be used as a hook for suspending steel bars S, etc. Of course, it can also be configured to move the hook mounting part provided on the left side 10b or right side 10c side of the body part 10 towards the upper 10a side of the body part 10. Therefore, since one hook 200B can be used appropriately according to various work site conditions, costs can be reduced compared to using two hooks.

[0075] <Third Embodiment> In the third embodiment of the rebar bundling machine 1C, the hook 200C can be retracted to the side of the main body 10 without using the hook 200C, which differs from the first embodiment of the rebar bundling machine 1A. Furthermore, for components that have substantially the same function as the rebar bundling machine 1A of the above embodiments, repeated descriptions are omitted by using the same symbols.

[0076] [Example of the structure of rebar bundling machine 1C] Figure 10 is a perspective view viewed from the rear left side of the rebar bundling machine 1C according to the third embodiment. Figure 11A is a cross-sectional view showing the fastener 520 connected with the hook 200C, and Figure 11B is a perspective view showing the state in which the hook 200C, which is installed on the hook mounting part 510a, is locked in the retracted position P2.

[0077] The rebar bundling machine 1C series includes hook mounting parts 510a and 510b that support the hook 200C in a movable position P1 (refer to Figure 10) from the upper 10a side of the main body 10 towards a retracted position P2 (refer to Figure 12) on the left side 10b and the right side 10c side. Regarding the hook 200C series of the third embodiment, it has a pair of hook members 202a and 202b configured in a generally U-shape (J-shape). Furthermore, the hook 200C does not necessarily have to be U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0078] The hook mounting part 510a is configured to mount the hook member 202a so that it can rotate from the top 10a side of the main body 10 toward the left side 10b side. The hook mounting part 510a is configured, for example, by a planar hinge, and with the base end of the hook member 202a inserted into its tube, the guide surface 250a and the left side 250c of the cover 250 are fastened by screws 512.

[0079] The hook mounting part 510b is configured such that the hook member 202b is mounted so that it can rotate from the top 10a side of the main body 10 towards the right side 10c side. The hook mounting part 510b is configured, for example, by a planar hinge, and with the base end of the hook member 202b inserted into its tube, the guide surface 250a and the right side 250d of the cover 250 are fastened by screws 514.

[0080] The hook mounting parts 510a and 510b are in the hook 200C, which includes hook members 202a and 202b, in which the opening 201c through which the reinforcing bar S is inserted is installed in a manner that the hook 200C is installed in the front side of the body part 10 in the front-rear direction.

[0081] As shown in Figures 10 and 11A, a fastener 520 with a hook portion on the top end of the hook member 202b constituting the hook 200C is rotatably mounted. The fastener 520 is used to join (integrate) the top ends of the hook members 202a and 202b by inserting the other hook member 200a into the hook portion when the top ends of the hook members 202a and 202b protrude above the body part 10.

[0082] Hook 200C is biased toward the rear of body 10 by springs 516 and 518. As shown in Figure 11B and Figure 12 (described later), pin 203a is inserted into and protrudes from hook member 202a of hook 200C. In hook mounting part 510a, slots 511a1 and 511a2 are provided in two locations corresponding to the use position P1 and the retracted position P2. Similarly, although some figures are omitted, pin 203b is also inserted into hook member 202b and protrudes, and slots 511b1 and 511b2 are provided in two locations in hook mounting part 510b. By biasing the pins 203a and 203b inserted into the hook 200C by springs 516 and 518, the pins enter grooves 511a1 and 511b1 respectively in the use position P1, and enter grooves 511a2 and 511b2 respectively in the retracted position P2, thereby restricting the rotation of the hook 200C.

[0083] [Example of operation of rebar bundling machine 1C]

[0084] Figure 12 shows the operation of the rebar bundling machine 1C when the hook 200C moves from the use position P1 to the retreat position P2.

[0085] As shown in Figure 11A, in the hook 200C in the use position P1, by rotating the hook portion of the fixing member 520 away from the hook member 202a, the fixing member 520 is disengaged from the hook member 202a, and the hook members 202a and 202b are separated.

[0086] Next, as shown in Figure 12, by pushing the hook member 202a forward, the pin 203a disengages from one of the slots 511a15, and rotates from the use position P1 on the upper 10a side of the body part 10 towards the retracted position P2 on the left side 10b side of the body part 10, thus housing the hook member 202a on the left side 10b side of the body part 10. Because the hook member 202a is biased by the spring 516, the pin 203a is engaged in the other slot 511a2 (see Figure 11B) and will not rotate from the housing position. Similarly, by pushing the hook member 202b forward, the pin 203b disengages from one of the slots 511b1, and rotates from the use position P1 on the upper 10a side of the body part 10 towards the retracted position P2 on the right side 10c side, thus housing the hook member 202b on the right side 10c side of the body part 10. Because the hook member 202b is biased by the spring 518, the pin 203b is inserted into the groove 511b2 on the other side and will not rotate from the receiving position.

[0087] As described above, according to the third embodiment, for example, if the hook 200C on the upper surface 10a of the main body 10 becomes obstructed during the binding operation, the hook 200C can be retracted from the upper surface 10a of the main body 10 toward the left side 10b, etc. In this way, the efficiency of the operation can be improved.

[0088] <Fourth Embodiment>

[0089] In the rebar bundling machine 1D of the fourth embodiment, the hook mounting part 210a and the like are only provided on the upper 10a side of the main body 10. Furthermore, for components that have substantially the same function as the rebar bundling machine 1A of the above embodiment, repeated descriptions are omitted by using the same reference numerals.

[0090] Figure 13 is a perspective view of the steel bar bundling machine 1D from the rear left side of the fourth embodiment.

[0091] As shown in Figure 13, the rebar bundling machine 1D system includes a main body 10, a bundling part 4 having a curling forming part 5 and a twisting part 7 provided at the front end of the long side of the main body 10, and a drive part 8 for driving the bundling part 4 housed inside (refer to Figure 4). The rebar bundling machine 1D system includes a box 2 provided on the lower 10e side of the main body 10 and for feeding and accommodating wire W, a gripping part 11 provided behind the box 2 on the lower 10e side of the main body 10, and a plurality of hook mounting parts 210a to 210e located on the upper 10a side of the main body 10 for mounting a U-shaped hook 200A with one side opening. In this embodiment, the hook 200A is formed by a U-shaped side shape, but it does not have to be U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0092] The hook mounting portion 210d and the like are provided along the longitudinal direction (long side direction) of the guide surface 250a of the cover portion 250. The hook mounting portion 210d and the like are used to mount the hook 200A with the opening 201 of the hook 200A facing the front side of the body portion 10 in the longitudinal direction. Furthermore, the number of hook mounting portions 210d and the like is not limited to the five described in the first embodiment, but can be any number. Also, the hook mounting portions 210d and the like can be directly provided on the upper surface 10a of the body portion 10.

[0093] As shown in Figure 8A, the hook mounting part 210d and the like can also be mounted such that the hook 200A can move from the upper 10a side of the body part 10 toward the rear 10d side. Furthermore, as shown in Figure 10, the hook mounting part 210d and the like can also be mounted such that the hook 200A can move from the upper 10a side of the body part 10 toward at least one of the left side 10b side and the right side 10c side.

[0094] As described above, in the fourth embodiment of the rebar bundling machine 1D, because the body part 10 has a box 2 for holding wire W and a gripping part 11 on the lower 10e side, the center of gravity C of the rebar bundling machine 1D is below the body part 10, more specifically near the box 2. Therefore, when the rebar bundling machine 1D is suspended from the rebar S, etc., by means of the relationship with the center of gravity position, the rebar bundling machine 1D will not tilt (operate) too much and become unstable, and can be held stably. In other words, because the rebar bundling machine 1D is stably suspended from the rebar S, etc., problems such as the rebar bundling machine 1D falling from the rebar are unlikely to occur. Furthermore, the hook mounting part 210 is designed so that the hook 200 is installed on the upper 10a side of the main body 10 with the opening 201 of the hook 200 facing forward. Therefore, when the hook 200 is installed in the hook mounting part 210, after the binding operation of the rebar S located in front of the operator, the rebar S can be hoisted with minimal wrist movement while tilting the front end of the main body 10 with the curling guide 5 downward. Thus, when repeating the use of the rebar binding machine 1D and the hoisting operation when not in use, work efficiency is improved, and the workload of the operator is also reduced.

[0095] <Fifth Embodiment> In the rebar bundling machine 1E of the fifth embodiment, the hook mounting part 310 is only provided on the left side 10b side of the main body 10. Furthermore, for components that have substantially the same function as the rebar bundling machine 1A of the above embodiments, repeated descriptions are omitted by using the same symbols.

[0096] Figure 14 is a perspective view viewed from the rear left side of the rebar bundling machine 1E according to the fifth embodiment.

[0097] As shown in Figure 14, the rebar bundling machine 1E includes a main body 10. A bundling section 4 with a coiling forming section 5 and a twisting section 7 is provided at the front end of the main body 10 along its long side. A drive section 8 for driving the bundling section 4 is housed inside (refer to Figure 4). The rebar bundling machine 1E includes a cartridge 2 located on the lower 10e side of the main body 10 and capable of feeding and housing the wire W; a gripping section 11 located on the lower 10e side of the main body 10 and behind the cartridge 2; and a hook mounting section 310 located on the left side 10b side of the main body 10, on which a U-shaped hook 300 with one side opening can be mounted. In this embodiment, the hook 300 is formed by a U-shaped side profile, but it does not necessarily have to be U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0098] The hook mounting part 310 is provided in the overhanging part 250e of the cover part 250. The hook mounting part 310 is installed such that the opening 301 of the hook 300 faces the center of gravity C of the rebar binding machine 1E (refer to Figure 3). Furthermore, the hook mounting part 310 is installed such that the opening 301 of the hook 300 faces the lower side of the body part 10 in the vertical direction. Moreover, as shown in Figure 7, multiple hook mounting parts 310 may be provided, and they may be directly provided on the left side 10b of the body part 10. Alternatively, the hook mounting part 310 may be provided on the right side 10c of the body part 10, or on both the left side 10b and the right side 10c.

[0099] As described above, in the fifth embodiment of the rebar bundling machine 1E, because the body 10 has a housing 2 for holding wire W and a gripping part 11 on the lower 10e side, the center of gravity C of the rebar bundling machine 1E is below the body 10, more specifically near the housing 2. Therefore, when the rebar bundling machine 1E is suspended from the rebar S, etc., by means of the relationship with the center of gravity, the rebar bundling machine 1E will not tilt (operate) significantly and become unstable, and can be held stably. In other words, because the rebar bundling machine 1E is stably suspended from the rebar S, etc., problems such as the rebar bundling machine 1E falling from the rebar S, etc., are unlikely to occur. Furthermore, the hook mounting part 310 is installed with the hook 300 on the left side 10b of the main body 10 and the opening 301 of the hook 300 facing downwards. Therefore, when the rebar bundling machine 1E is suspended on the rebar S, the left side 10b of the main body 10 is kept approximately parallel to the rebar S in the front-rear direction. As a result, the protrusion of the main body 10 is reduced when the rebar S is being suspended, and the operation is not hindered even when the rebar bundling machine 1E is suspended, allowing for smooth movement or operation at the work site.

[0100] <Sixth Embodiment> In the sixth embodiment of the rebar bundling machine 1F, the housing 2 is located on the side of the main body 10, which differs from the first embodiment of the rebar bundling machine 1A. Furthermore, for components that have substantially the same function as the rebar bundling machine 1A of the above embodiments, repeated descriptions are omitted by using the same reference numerals.

[0101] Figure 15 is a perspective view viewed from the rear right side of the rebar bundling machine 1F of the sixth embodiment.

[0102] As shown in Figure 15, the rebar bundling machine 1F series includes a main body 10, a bundling part 4 having a coiling forming part 5 and a twisting part 7 provided at the front end of the main body 10 along its long side, and a drive part (see Figure 4) for driving the bundling part 4 housed inside (see Figure 4). The rebar bundling machine 1F series includes a box 2 provided at the rear end of the main body 10 in the front-rear direction and for feeding and housing the wire W, and a gripping part 11 provided on the lower 10e side of the main body 10.

[0103] Furthermore, the rebar bundling machine 1F system includes a first hook mounting part 210 located on the upper 10a side of the main body 10, on which a U-shaped first hook 200A with one side opening can be mounted. In this embodiment, the first hook 200A is formed by a U-shaped side shape, but it does not necessarily have to be U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0104] The second type of housing is positioned near the right side 10c of the main body 10, to avoid the torsion section 7 and drive section 8 located on the left side of the main body 10. The second type of housing is constructed by a space that can accommodate a spool of wound wire W.

[0105] Furthermore, on the rear side of the main body 10, as shown in Figure 15, a cover 22 is provided, which provides a space for opening and closing the box 2. The cover 22 is mounted on a support shaft 24 provided on the upper part 10a of the main body 10, and is configured to rotate toward the closed box 2 position and the open box 2 position with the support shaft 24 as a fulcrum.

[0106] A first hook mounting portion 210 is provided on the upper part of the case cover portion 22. The first hook mounting portion 210 is used to mount the first hook 200A with the opening 201 of the first hook 200A facing the front side of the main body portion 10 in the front-rear direction. The first hook 200A is mounted on the case cover portion 22 by inserting the engaging piece 202 (refer to Figure 2) into the engaging hole 212a formed in the case cover portion 22, and the screw 206 is screwed into the screw hole 214a formed in the case cover portion 22 through the insertion hole 204 (refer to Figure 2).

[0107] Furthermore, as described in the first embodiment, multiple first hook mounting portions 210 may be provided, or they may be directly mounted on the upper surface 10a of the main body 10. Also, as shown in Figure 8A, the first hook mounting portion 210 may be mounted such that the first hook 200A can move from the upper surface 10a side of the main body 10 towards the rear surface 10d side. Furthermore, as shown in Figure 10, the first hook mounting portion 210 may be mounted such that the first hook 200A can move from the upper surface 10a side of the main body 10 towards at least one of the left side 10b side and the right side 10c side.

[0108] Furthermore, as described in the first embodiment, a second hook mounting portion 310 may be provided on at least one of the left side surface 10b and the right side surface 10c of the main body portion 10. In this case, the second hook mounting portion 310 is configured such that, when viewed from the front (front view) of the main body portion 10, the opening 201 of the first hook 200A mounted on the first hook mounting portion 210 is not obstructed. Also, the second hook mounting portion 310 is configured such that the second hook 300 does not protrude from the top surface 10a or the cover portion 22 of the main body portion 10.

[0109] Furthermore, the second hook mounting part 310 is configured such that the opening 301 of the second hook 300 is located on the lower side of the rebar bundling machine 1F in the front-rear direction and faces the center of gravity D of the rebar bundling machine 1F. Here, the center of gravity D of the rebar bundling machine 1F is determined by the weight of the main body 10, the coiling forming part 5, the box 2, the gripping part 11, the battery 15, etc., and their arrangement. In this embodiment, since the box 2, which is one of the weights, is located at the front-rear end of the main body 10, the box 2, which is slightly behind the trigger 12, is located at the connection between the lower part 10e of the main body 10 and the upper part of the gripping part 11.

[0110] As described above, in the sixth embodiment of the rebar bundling machine 1F, because a housing 2 is located at the rear end of the main body 10 in the front-rear direction, the center of gravity D of the rebar bundling machine 1F is near the housing 2. Therefore, when the rebar bundling machine 1F is suspended from the rebar S, etc., by means of the hook 200A installed on the hook mounting part 210, the rebar bundling machine 1F will not tilt (operate) significantly and become unstable, and can be held stably. In other words, because the rebar bundling machine 1F is stably suspended from the rebar S, etc., problems such as the rebar bundling machine 1F falling from the rebar S, etc., are unlikely to occur.

[0111] Furthermore, according to the rebar bundling machine 1F, the hook mounting part 210 is installed with the hook 200 on the upper 10a side of the main body 10 and the opening 201 of the hook 200 facing forward. Therefore, when the hook 200 is installed in the hook mounting part 210, after bundling the rebar S and the like located in front of the operator, the rebar S and the like can be hoisted with minimal wrist movement while tilting the front end side of the main body 10, which has the curling forming part 5, etc., downward. Therefore, when repeating the use of the rebar bundling machine 1F and the hoisting action when not in use, the work efficiency is improved, and the workload of the operator is also reduced.

[0112] The preferred embodiments of this disclosure have been described in detail above with reference to the drawings, but the scope of the technology disclosed is not limited to these examples. For example, in the above embodiments, the case of a rebar bundling machine 1A or the like has been described, but other than a rebar bundling machine 1A, a nailing machine and a screw fastening machine can also be cited as tools, and the hook mounting part described above is also applicable to nailing machines and screw fastening machines.

[0113] In the above embodiments, the first hook mounting portion 210a, etc., is constructed by the engaging hole 212a into which the engaging piece 202 of the first hook 200A is inserted, and the screw hole 214a into which the screw 206 is screwed. However, it is not limited to these configurations. For example, other conventional fastening methods such as embedded fastening can be used without fixing the screw. Furthermore, the same applies to the other second hook mounting portions 310, etc., as described in the above embodiments.
