Description

Technical Field

[0001] This disclosure relates to tools and strapping machines. Background Technology

[0002] Tools such as rebar tying machines, nailing machines, and screw tightening machines include those with hooks installed on the tool body or clamps. These hooks are used to hook onto the belt attached to the worker's trousers when the tool is not in use or when moving the tool, or to hook the tool onto scaffolding or footstools placed on site when the tool is not in use.

[0003] For example, Patent Document 1 describes a screw tightening machine with a pair of upper and lower insertion holes formed on the side opening of the head, and a hook device installed in the insertion holes. In addition, Patent Document 2 describes a hook support member fixed to the rear of a clip formed at one end of the main body, and a hook insertion tool for which a hook is obtained by bending and connecting a hooking part and a sliding shaft part is installed on the hook support member.

[0004] In situations where rebar laying and tying operations alternate on a work site, such as rebar laying into walls or columns, or tying the laid rebar with binding wire, the tool (rebar tying machine) is often hung on the worker's belt or placed on scaffolding during rebar laying. However, compared to hanging the tool on a belt or placing it on scaffolding, tying the tool to the laid rebar allows for a smoother transition to the next operation (tying operation), which is advantageous in terms of work efficiency.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2006-150503

[0007] Patent Document 2: Japanese Patent No. 4877488 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] However, when the hook is installed on the side of the main body with the opening of the hook facing forward, as disclosed in Patent Document 1, the tool tilts significantly and becomes unstable when it is hooked onto a steel bar or similar object and the hand is removed, causing the tool to easily fall off the steel bar. Furthermore, because the tool tilts (moves) significantly when the hand is removed, it easily comes into contact with surrounding steel bars or similar objects, potentially damaging the surrounding steel bars or the tool itself.

[0010] In addition, in the tool disclosed in Patent Document 2, since a hook is provided on the lower side of the handle, when hooking the hook to steel bars, footstools, etc., the operator needs to flip his wrist while hooking, which has the problem of difficulty in hooking and inability to quickly move to the next task.

[0011] The present invention addresses the aforementioned issues and aims to provide a tool and binding machine that can easily clamp onto components such as reinforcing bars at the work site without causing significant tilting when clamped.

[0012] Methods for solving problems

[0013] The tool disclosed herein comprises: a main body having an output portion at its front end in the longitudinal direction, and a drive portion for driving the output portion housed inside; a gripping portion disposed on the lower surface side of the main body; a first hook mounting portion located on the upper surface side of the main body, to which a hook with an opening on one side can be mounted; and a second hook mounting portion located on the side side of the main body, to which the hook can be mounted. The first hook mounting portion mounts the hook such that the opening of the hook faces the front side of the main body in the longitudinal direction, and the second hook mounting portion mounts the hook such that the opening of the hook faces the lower side of the main body in the vertical direction.

[0014] The first strapping machine disclosed herein comprises: a main body having a strapping section for strapping wires at its front end in the longitudinal direction, and a drive section for driving the strapping section housed therein; a storage section disposed on the lower surface of the main body for storing the strapping wires in a manner that allows them to be delivered; a gripping section disposed on the lower surface of the main body and behind the storage section; and a hook mounting section located on the upper surface of the main body, wherein a hook with an opening on one side can be mounted on the hook mounting section, and the hook mounting section mounts the hook such that the opening of the hook faces the front side of the main body in the longitudinal direction.

[0015] The second strapping machine disclosed herein includes: a main body portion having a strapping part for strapping wires at its front end in the longitudinal direction, and a drive part for driving the strapping part housed inside; a storage part disposed on the lower surface side of the main body portion for storing the strapping wires in a way that allows them to be delivered; and a gripping part disposed on the lower surface side of the main body portion and behind the storage part. The strapping machine includes a hook mounting part, wherein the hook mounting part is located on the side side of the main body portion and a hook with an opening on one side can be mounted on the hook mounting part, and the hook mounting part mounts the hook with the opening of the hook facing the center of gravity of the strapping machine.

[0016] The third strapping machine disclosed herein comprises: a main body having a strapping part for strapping wires at its front end in the longitudinal direction, and a drive part for driving the strapping part housed therein; a storage part being provided at the rear end of the main body in the longitudinal direction for storing the strapping wires in a way that allows them to be delivered; a gripping part being provided on the lower surface side of the main body; and a hook mounting part being located on the upper surface side of the main body, wherein a hook with an opening on one side can be mounted on the hook mounting part, and the hook mounting part mounts the hook such that the opening of the hook faces the front side of the main body in the longitudinal direction.

[0017] Invention Effects

[0018] According to the tool disclosed herein, because the first hook mounting part is installed with the hook on the upper surface of the main body and the opening of the hook facing forward, when the hook mounted on the first hook mounting part is engaged with a component such as a steel bar, wall, or column located in front of the operator, engagement can be performed with less movement without tilting the front end of the main body containing the output part downward and flipping the wrist. Therefore, work efficiency is increased and the operator's workload is reduced when repeatedly using the tool and engaging the hook when not in use.

[0019] Furthermore, because the second hook mounting part is installed with the hook on the side of the main body and the opening of the hook facing downwards, when a tool is hooked onto a component such as a rebar or wall, the main body is kept approximately parallel to the rebar or wall along its length. Therefore, the amount of protrusion of the main body relative to the hooked component is reduced, and even if a tool is hooked, it will not hinder operation, allowing for smooth movement and work at the work site.

[0020] Furthermore, since the first hook mounting part and the second mounting part, which have the effects described above, are provided in one tool, it is possible to improve work efficiency and reduce the burden on the operator in a variety of situations in a variety of work sites.

[0021] Because the first binding machine of this disclosure has a storage part and a holding part for storing binding wire on the lower surface of the main body, the center of gravity of the binding machine is located below the main body, more specifically near the storage part. Therefore, when such a binding machine is hooked onto a component such as a reinforcing bar by the hook installed on the hook mounting part, due to the aforementioned center of gravity position, the binding machine will not tilt (move) significantly and become unstable, and can be held stably. That is, the binding machine is stably hooked onto the component, so problems such as the binding machine falling off the reinforcing bar are less likely to occur. In addition, since the hook mounting part is installed on the upper surface of the main body with the opening of the hook facing forward, when the hook is installed on the hook mounting part, after binding the reinforcing bar relative to the reinforcing bar in front of the operator, it is possible to hook the reinforcing bar (the component being hooked) with less movement without tilting the front end of the main body containing the binding part downward and flipping the wrist. Therefore, when repeatedly using and hooking the binding machine, the work efficiency is increased and the operator's workload is reduced.

[0022] Because the second binding machine of this disclosure has a storage part and a holding part for storing binding wire on the lower surface of the main body, the center of gravity of the binding machine is located below the main body, more specifically near the storage part. Therefore, when such a binding machine is hooked onto a component such as a reinforcing bar by a hook installed on the hook mounting part, due to the aforementioned center of gravity position, the binding machine will not tilt (move) significantly and become unstable, and can be held stably. That is, the binding machine is stably hooked onto the component, so problems such as the binding machine falling off the reinforcing bar are less likely to occur. In addition, since the hook mounting part is installed on the side of the main body with the opening of the hook facing downwards, when the binding machine is hooked onto a component such as a reinforcing bar or a wall, the main body is held so that the side of the main body in the longitudinal direction is approximately parallel to the reinforcing bar, wall, etc. Therefore, the amount of protrusion of the main body relative to the component being hooked can be reduced, and even if the binding machine is hooked, it will not hinder the operation, allowing for smooth movement and operation at the work site.

[0023] According to the third binding machine disclosed herein, because the hook mounting part is installed with the hook on the upper surface of the main body and the opening of the hook facing forward, when the hook is installed in the hook mounting part, after binding the reinforcing bar located in front of the operator, it is possible to clamp the reinforcing bar (the clamped part) with less movement without tilting the front end of the main body containing the binding part downward and flipping the wrist. Therefore, when repeatedly using the binding machine and clamping actions when not in use, work efficiency is increased and the operator's workload is reduced. Attached Figure Description

[0044] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0045] <First Implementation Method>

[0046] [Structural Example of Rebar Tying Machine 1A]

[0047] Figure 1 This is a perspective view of the rebar tying machine 1A according to the first embodiment, viewed from the rear left side. Figure 2 This is an exploded three-dimensional view of the rebar tying machine 1A as viewed from the left front side. Figure 3 This is a left view of the rebar tying machine 1A according to the first embodiment. Figure 4 This is a diagram of a portion of the rebar tying machine 1A that is not displayed. Figure 5 This is a front view of the rebar tying machine 1A according to the first embodiment. It should be noted that the rebar tying machine 1A is an example of a tool or tying machine, and in this specification, the rebar tying machine 1A is sometimes referred to as a tool or tying machine.

[0048] The rebar tying machine 1A includes a main body 10 consisting of a generally rectangular parallelepiped-shaped shell. A tying section (output section) 4 is provided at one end (front end) of the main body 10 along its length, and a drive section 8 for driving the tying section 4 is housed inside the main body 10. Furthermore, the rebar tying machine 1A has a material box (storage section) 2 at one end of the main body 10 along its width (orthogonal to the length direction), i.e., on the lower surface 10e side of the main body 10, which stores the tying wire W in a way that allows it to be fed out. A holding section 11 is provided at the lower surface 10e side of the main body 10 and behind the material box 2 (in the aforementioned length direction). The tying section 4 has a coiling forming section 5 that protrudes from the front end of the main body 10 and coils the tying wire W fed from the material box 2, and a twisting section 7 that twists the tying wire W coiled by the coiling forming section 5.

[0049] The rebar tying machine 1A includes a first hook mounting part 210 located on the upper surface 10a side of the main body 10 (opposite to the lower surface 10e side, separated from the main body 10) where a U-shaped first hook 200A with an opening on one side can be mounted, and a second hook mounting part 310 located on the left side 10b side of the main body 10 where a second hook 300 can be mounted. It should be noted that in this embodiment, the upper surface 10a side includes not only the upper surface 10a of the main body 10 but also the area near the boundary between the upper surface 10a of the main body 10 and the left side 10b, right side 10c, or rear end surface.

[0050] The rebar tying machine 1A includes a cover 250 that is provided along the front-to-back direction (length direction) to cover at least a portion of the upper surface 10a of the main body 10. The cover 250 has a guiding surface 250a for guiding the rebar S to the opening 201 of the first hook 200A when the rebar (the part being hooked) S is hooked to the first hook 200A, such as the first hook mounting part 210a.

[0051] like Figures 1-5 As shown, the material box 2 is located at a relatively forward position of the main body 10, extending downward from the lower surface 10e of the main body 10. A spool is housed inside the material box 2 in a rotatable and detachable manner, and a long strip of binding wire W is wound around the spool in a way that allows it to be unwound. Regarding the binding wire W, in addition to binding wire made of deformable metal wire, binding wire made by coating metal wire with resin or binding wire made of stranded wire are also used.

[0052] The gripping part 11 is a part for the operator to hold during operation or handling, and is provided on the lower surface 10e side of the main body 10. The gripping part 11 is provided behind the material box 2 and faces the material box 2, extending downward from the lower surface 10e of the main body 10. A trigger 12 is provided at the front base of the gripping part 11 for the operator to open and close the binding action. It should be noted that the execution of the binding action can also be combined with the operation of the contact switch 9 provided at the front end of the main body 10. The gripping part 11 has a battery mounting part at the lower front end for the removable installation of the battery 15.

[0053] like Figure 1 and Figure 2 As shown, the cover 250 is composed of a slender flat plate member with a roughly U-shaped cross-section that extends in the front-rear direction, covering the entire upper surface 10a of the main body 10. The upper surface of the cover 250 serves as a guide surface 250a for slidably guiding the reinforcing bar S from the front of the main body 10 toward the opening 201 of the first hook 200A. An inclined surface 250b, continuous with the guide surface 250a and gradually increasing in elevation from front to rear, is provided on the front end side of the cover 250. When the reinforcing bar S is hooked onto the first hook 200A, the inclined surface 250b picks up the reinforcing bar S and guides it into the opening 201 of the first hook 200A.

[0054] 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 rear sides of 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 fastening units 600 such as bolts and nuts.

[0055] like Figure 1 and Figure 2 As shown, the cover portion 250 has multiple first hook mounting portions 210a, 210b, 210c, 210d, and 210e extending from the front side of the guide surface 250a towards the rear side. By providing multiple first hook mounting portions 210a, the mounting position of the first hook 200A can be selected and changed according to the usage environment and the operator's preferences. It should be noted that 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 directly provided on the main body portion 10. In addition, five first hook mounting portions 210a, etc., are provided, but the number is not limited to five.

[0056] The first hook mounting part 210a has a locking hole 212a for the locking piece 202 of the first hook 200A to be inserted into, and threaded holes 214a, 214a for screws 206, 206 to be screwed in. The first hook mounting part 210d has a locking hole 212d for the locking piece 202 of the first hook 200A to be inserted into, and threaded holes 214d, 214d for screws 206, 206 to be screwed in. It should be noted that the first hook mounting parts 210b, 210c, and 210e have the same structure as the first hook mounting parts 210a, etc., and therefore detailed descriptions are omitted.

[0057] like Figures 1-5 As shown, the first hook 200A is a component used to hook the rebar tying machine 1A onto the rebar S. In this embodiment, it is composed of a flat plate component bent into a U-shape on the side. In this embodiment, the first hook 200A has a slit along its length, forming a two-strand shape, but it is not limited to this shape. It should be noted that the first hook 200A is not necessarily U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped. That is, the first hook 200A only needs to have a hooking part for hooking onto the rebar and a fixing part for fixing onto the cover 250 or the main body 10. Hereinafter, the case of installing the first hook 200A onto the first hook mounting part 210d will be described.

[0058] like Figure 2 As shown, a locking piece 202 and through holes 204, 204 are provided on the base end side (the end on the 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 main 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 at positions facing the threaded holes 214d, 214d of the first hook mounting portion 210d.

[0059] In this embodiment, the engaging piece 202 of the first hook 200A is fitted into the engaging hole 212d of the first hook mounting portion 210d, and the screws 206, 206 are screwed into the threaded holes 214d, 214d of the first hook mounting portion 210d via the through holes 204, 204, thereby fixing the first hook 200A to the main body portion 10 (cover portion 250). At this time, as Figure 3 As shown, the first hook 200A is installed on the first hook mounting part 210d in such a way that the opening 201 for inserting the reinforcing bar S faces the front side in the front-rear direction.

[0060] like Figures 1-3As shown, the second hook mounting part 310 is provided in the protrusion 250e extending downward from the left side part 250c of the cover part 250. The second hook mounting part 310 has a locking hole 312 for engaging the locking piece 302 of the second hook 300 and threaded holes 314, 314 for engaging the screws 306, 306.

[0061] It should be noted that in this embodiment, the second hook mounting part 310 is provided on the left side 10b of the main body 10, but it can also be provided on the right side 10c of the main body 10, or on both the left side 10b and the right side 10c of the main body 10. Alternatively, the second hook mounting part 310 can be provided directly on the main body 10 instead of on the cover part 250.

[0062] The second hook 300 is a component used to hook the rebar tying machine 1A onto the rebar S from the left side 10b. Like the first hook 200A, it is composed of a flat plate bent into a U-shape. In this embodiment, the second hook 300 has a slit along its length, forming two strands, but is not limited to this shape. It should be noted that, like the first hook 200A, the second hook 300 is not necessarily U-shaped; for example, it could be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0063] like Figure 2 and Figure 5 As shown, a locking piece 302 and through holes 304, 304 are provided on the base end side (the end on the side of the second hook mounting portion 310) of the second hook 300. The locking piece 302 is formed to protrude from the base end of the second hook 300 toward the main 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 at positions facing the threaded holes 314, 314 of the second hook mounting portion 310.

[0064] 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, 306 are screwed into the threaded holes 314, 314 of the second hook mounting part 310 via the insertion holes 304, 304, thereby fixing the second hook 300 to the left side surface 10b (cover part 250) of the main body part 10.

[0065] In this case, the second hook mounting part 310 is positioned such that, when viewed from the front (front view) of the main body part 10... Figure 3 and Figure 5The second hook 300 is installed in a manner that does not obstruct the opening 201 of the first hook 200A, such as the first hook mounting portion 210d. Furthermore, the second hook mounting portion 310 is configured to prevent the second hook 300 from protruding from the guide surface 250a of the cover portion 250. It should be noted that, without the cover portion 250, the second hook mounting portion 310 is configured to prevent the second hook 300 from protruding from the upper surface 10a of the main body portion 10. Additionally, the second hook mounting portion 310 can also be configured such that the opening 301 of the second hook 300 faces downwards or diagonally downwards in the vertical direction of the main body portion 10 and towards the center of gravity C of the rebar tying machine 1A.

[0066] Here, the center of gravity C of the rebar tying machine 1A is determined by the weight and arrangement of the main body 10, the coiling and forming section 5, the material box 2, the gripping section 11, and the battery 15. The material box 2, which is heavier than other structures (such as the coiling and forming section 5 and the gripping section 11) due to its ability to hold the binding wire W, is located in front of the lower surface 10e of the main body 10. Figure 3 As shown, in this embodiment, the center of gravity C of the rebar tying machine 1A is located in the space in front of the trigger 12 and near the material box 2; in other words, it is located in the space between the trigger 12 and the upper part of the material box 2. It should be noted that in the rebar tying machine 1A, as the number of binding wires W stored in the material box 2 decreases due to their use, the overall weight of the rebar tying machine 1A also decreases. In this case, the center of gravity C of the rebar tying machine 1A will shift slightly, but the center of gravity C will not change significantly.

[0067] like Figure 4 As shown, the binding wire conveying unit 3 includes a pair of conveying gears 30 that clamp and convey one or more binding wires W arranged in parallel, and a conveying motor (not shown) that drives the conveying gears 30. In the binding wire conveying unit 3, the rotational motion of the conveying motor is transmitted via a transmission mechanism, thereby rotating the conveying gears 30. The binding wire conveying unit 3 conveys the binding wires W clamped between the pair of conveying gears 30 along the extension direction of the binding wires W. In the structure for conveying multiple binding wires W, such as two, the two binding wires W are conveyed in a parallel manner.

[0068] The coiling forming section 5 includes a coiling guide 50 for coiling the binding wire W conveyed by the binding wire conveying section 3, and an induction guide 51 for guiding the coiled binding wire W, after being coiled by the coiling guide 50, toward 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 tying machine 1A, the path of the binding wire W conveyed by the binding wire conveying section 3 is restricted by the coiling forming section 5, and the binding wire W is coiled around the rebar S.

[0069] like Figure 4As shown, the cutting section 6 includes: a fixed blade section 60, a movable blade section 61 that cuts the binding wire W in cooperation with the fixed blade section 60, and a transmission mechanism 62 that transmits the motion of the twisting section 7 to the movable blade section 61. The cutting section 6 cuts the binding wire W by rotating the movable blade section 61 with the fixed blade section 60 as the fulcrum.

[0070] The torsion section 7 includes a binding wire clamping body 70 for securing the binding wire W and a rotating shaft 72 for actuating the binding wire clamping body 70. The drive section 8 includes a motor 80 and a reducer 81 for speed reduction and torque amplification. In the torsion section 7 and the drive section 8, the rotating shaft 72 and the motor 80 are connected via the reducer 81, and the rotating shaft 72 is driven by the motor 80 via the reducer 81. The binding wire clamping body 70 includes a sleeve 71 that actuates a first side hook and a second side hook (not shown) in conjunction with the rotational movement of the rotating shaft 72.

[0071] The binding wire W, conveyed by the binding wire conveying unit 3, is guided towards the coiling forming unit 5 via the binding wire locking body 70. Furthermore, the front end of the binding wire W, coiled by the coiling forming unit 5 and guided to the twisting unit 7, is locked in a manner that prevents it from detaching from the binding wire locking body 70. Next, when the binding wire W is cut by the cutting unit 6, the sleeve 71 moves forward, thereby bending the front end of the binding wire W locked by the binding wire locking body 70 and the end end of the binding wire W cut by the cutting unit 6 towards the reinforcing bar S.

[0072] When the binding wire W is bent toward the reinforcing bar S at both the front and rear ends, and the sleeve 71 moves further forward, the sleeve 71 rotates in conjunction with the rotating shaft 72, and the binding wire W, which is held in place by the binding wire retainer 70, is twisted.

[0073] [Example of using the first hook 200A]

[0074] Figure 6A An example of the use of the first hook 200A is shown. For example, after the binding operation (binding the reinforcing bar S with binding wire W) is completed and the curling forming part 5 on the front end side of the main body 10 is detached from the reinforcing bar S, the operator can tilt the curling forming part 5 downwards, so that the upper surface 10a side of the main body 10 faces the reinforcing bar arrangement surface, i.e., the reinforcing bar S. While the guide surface 250a of the cover 250 is along the reinforcing bar arrangement surface or the guide surface 250a is abutting against the reinforcing bar S (while the reinforcing bar S slides on the guide surface 250a), the operator moves the reinforcing bar binding machine 1A downwards to hook the reinforcing bar S onto the first hook 200A. Therefore, when hooking the first hook 200A onto the reinforcing bar S, the operator only needs to tilt the reinforcing bar binding machine 1A downwards and move it, without needing to perform actions such as flipping the wrist to rotate the reinforcing bar binding machine 1A. Therefore, work efficiency is increased, and the operator's workload is reduced.

[0075] [Example of using the second hook 300]

[0076] Figure 6B An example of the use of the second hook 300 is shown. For example, 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 rebar arrangement surface, thereby hooking the second hook 300 onto the rebar S. By hooking the rebar S onto the second hook 300 in this way, and keeping the rebar binding machine 1A in a manner where the main body 10 is approximately parallel to the rebar arrangement surface, the amount of protrusion of the main body 10 relative to the rebar S can be reduced. Even when the rebar binding machine 1A is hooked onto the rebar S, it will not hinder the operation, allowing for smooth movement and operation at the work site.

[0077] [Modified example of the second hook mounting part 310]

[0078] It should be noted that the second hook mounting part 310 is only required to install the second hook 300 on the left side 10b and right side 10c of the main body 10, such that the opening 301 of the second hook 300 faces the center of gravity C of the rebar tying machine 1A, and is not limited to this. Figure 1 The installation location is shown in the figure.

[0079] Figure 7 This is a diagram showing a modified example of the second hook mounting part 310. In addition to the second hook mounting part 310 described above, the rebar tying machine 1A also has second hook mounting parts 310A and 310B.

[0080] like Figure 7 As shown, the second hook mounting part 310A is inclined on the front side of the left side surface 10b of the main body 10 so that the opening 301 of the second hook 300 faces the center of gravity C of the rebar tying machine 1A. In this case, the second hook mounting part 310A is installed such that the second hook 300 does not protrude from the upper surface 10a of the main body 10 or the guiding surface 250a of the cover 250 and does not obstruct the opening 201 of the first hook 200A. Furthermore, the second hook 300 can also be installed using the same mounting method as the second hook mounting part 310B.

[0081] According to the first embodiment, since the first hook mounting part 210a, etc., mounts the first hook 200A to the upper surface 10a side of the main body 10 with the opening 201 of the first hook 200A facing forward, when the first hook 200A is mounted to the first hook mounting part 210a, etc., after the binding operation of the rebar S, etc., located in front of the operator, it is possible to hook the rebar S, etc., with less movement without tilting the front end side of the main body 10, which contains the curling forming part 5 and the twisting part 7, downward while flipping the wrist. Therefore, when repeatedly performing the hooking operation when using the rebar binding machine 1A and when not in use, the work efficiency is increased and the operator's workload is reduced.

[0082] Furthermore, because the rebar tying machine 1A has a material box 2 for storing tying wire W and a holding part 11 on the lower surface 10e side of the main body 10, the center of gravity C of the rebar tying machine 1A is located below the main body 10, more specifically near the material box 2. Therefore, when such a rebar tying machine 1A is hooked onto the rebar S via the first hook 200A installed on the first hook mounting part 210a, etc., due to the relationship with the center of gravity position, the rebar tying machine 1A will not tilt (operate) significantly and become unstable, and can be held stably. That is, the rebar tying machine 1A is stably hooked onto the rebar S, etc., so it is not easy for problems such as the rebar tying machine 1A falling off the rebar to occur.

[0083] Furthermore, because the second hook mounting part 310 mounts the second hook 300 to the left side 10b of the main body 10 with the opening 301 of the second hook 300 facing downwards, when the rebar tying machine 1A is attached to 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. Therefore, the amount of protrusion of the main body 10 relative to the rebar S is reduced, and even when the rebar tying machine 1A is attached, it does not hinder operation, allowing for smooth movement and operation at the work site.

[0084] Furthermore, according to the first embodiment, since the first hook mounting part 210a and the second mounting part 310, which have the effects described above, are provided in a rebar tying machine 1A, it is possible to improve work efficiency and reduce the burden on the operator in various situations at various work sites.

[0085] Furthermore, according to the first embodiment, since the second hook 300 is installed in the second hook mounting portion 310 in a manner that does not obstruct the opening 201 of the first hook 200A, and the second hook 300 is installed in the second hook mounting portion 310 in a manner that prevents the second hook 300 from protruding from the upper surface 10a of the main body portion 10 or the guiding surface 250a of the cover portion 250, it is possible to prevent the second hook 300 from becoming an obstacle when the first hook 200A is hooked onto the reinforcing bar S.

[0086] Furthermore, according to the first embodiment, by providing the cover portion 250 and the guiding surface 250a, the reinforcing bar S can be guided into the opening 201 of the first hook 200A while sliding, so the first hook 200A can be easily hooked onto the reinforcing bar S. In addition, by providing the cover portion 250, 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.

[0087] <Second Implementation Method>

[0088] In the second embodiment of the rebar tying machine 1B, it differs from the first embodiment of the rebar tying machine 1A in that the hook 200B can move and retract towards the rear of the main body 10. It should be noted that components having substantially the same function as the rebar tying machine 1A of the above embodiment are omitted from repeated description by using the same reference numerals.

[0089] [Structural Example of Rebar Tying Machine 1B]

[0090] Figure 8A This is a perspective view showing the hook 200B and hook mounting part 410 of the rebar tying machine 1B. Figure 8B This is a side view of hook 200B and hook mounting part 410.

[0091] like Figure 8A and Figure 8B As shown, the rebar tying machine 1B includes: a locking plate 700 for locking the hook 200B at the use position P1; and a hook mounting part 410 for supporting the hook 200B in a way that allows it to move from the use position P1 on the upper surface 10a side of the main body 10 to a retracted position P2 on the rear surface 10d side. Here, the use position P1 is the position where the hook 200B is on the upper surface 10a side of the main body 10 and can be hooked onto the rebar S. The retracted position P2 is the position where the hook 200B is on the rear surface 10d side of the main body 10 and will not become an obstruction or obstacle during operation and handling.

[0092] like Figure 8A As shown, the locking plate 700 is a flat plate component with a roughly U-shaped cross-section, covering the rear side of the upper surface 10a of the cover portion 250. Pressing parts 702, 702 are provided on the rear end side of the locking plate 700 for locking the hook 200B in the use position P1. (See diagram) Figure 8B As shown, the pressing portions 702, 702 are provided such that the hook 200B can be inserted downwards into them, and protrude (lift) upwards relative to the plane of the locking plate 700 by at least the thickness of the hook 200B. It should be noted that in this embodiment, the pressing portions 702, 702 are provided at two locations corresponding to the two strands of the hook 200B, but this is not a limitation, and can be appropriately changed according to the shape of the hook 200B.

[0093] The locking plate 700 has a left side portion 700a and a right side portion 700b that stand downwards from both ends in the left-right direction. For example... Figure 8A As shown, a first shaft 720 and a second shaft 722 extending in the left-right direction are respectively inserted into 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 it. The openings of the cover portion 250 supporting the first shaft 720 and the second shaft 722 are elongated holes (not shown in the figure), which enables the locking plate 700 to move in the front-back direction relative to the cover portion 250.

[0094] like Figure 8A and Figure 8B As shown, the hook mounting part 410 has a flat plate member 412 extending in the left-right direction of the main body part 10 and locking parts 414, 414 erected downward from both ends of the flat plate member 412. It should be noted that the locking parts 414 are a common structure on both sides, therefore, for convenience, only one side will be described below.

[0095] A folded portion 208 of the hook 200B is mounted on the center of the upper surface of the flat plate component 412 via a fastener 420. The folded portion 208 is a portion that folds over and extends from the base end of the hook 200B to the opposite side of the curved portion. The hook 200B is configured to be able to rotate about the axis of the fastener 420, thereby changing the orientation of the hook 200B.

[0096] like Figure 8B As shown, the locking part 414 is approximately circular in top view and is disposed inside the left side portion 250c of the cover 250. A third shaft 724 is inserted through the locking part 414 and the left side portion 250c of the cover 250. The opening 414c of the locking part 414 supporting the third shaft 724 is an elongated hole, configured such that the third shaft 724 can move relative to the locking part 414 in the front-rear direction.

[0097] like Figure 8A As shown, 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. Thus, the second shaft 722 and the third shaft 724 are respectively subjected to forces in mutually facing directions by the elastic force of the tension spring 726.

[0098] like Figure 8BAs shown, a positioning 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 predetermined intervals around the periphery of the locking portion 414. The first recess 414a engages with the positioning 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 positioning pin 730 when the hook 200B is in the retracted position P2, locking the hook 200B in the retracted position P2.

[0099] [Example of operation of rebar tying machine 1B]

[0100] Next, the operation of moving the hook 200B from the use position P1 on the upper surface 10a side of the main body 10 to the retraction position P2 on the rear surface 10d side of the main body 10 will be described. Figures 9A-9C This is a diagram showing the operation of the rebar tying machine 1B when the hook 200B moves from the working position P1 to the retracted position P2.

[0101] like Figure 9A As shown, the operator slides the locking plate 700, held by one hand, forward relative to the cover 250. Simultaneously, the pressing parts 702 move forward, deviating from the base end of the hook 200B, thereby releasing the lock on the hook 200B.

[0102] Next, the operator uses their other hand to hold hook 200B, as... Figure 9B As shown, the hook 200B is rotated rearward. As a result, the locking part 414 moves rearward relative to the third axis 724 through the opening 414c, thereby releasing the first recess 414a of the locking part 414 from the positioning pin 730, and the engagement state between the first recess 414a and the positioning pin 730 is released.

[0103] 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 engages with the positioning pin 730 because the locking part 414 is forced forward by the tension spring 726. Thus, hook 200B is held in the retracted position P2.

[0104] Next, as Figure 9CAs shown, the operator rotates the hook 200B 180° around the axis of the fixing member 420, so that the opening 201 of the hook 200B faces downwards, causing the hook 200B to flip up and down. Because the hook 200B is subjected to a forward force by the tension spring 726, the folded part 208 of the hook 200B contacts the rear surface 10d of the main body 10, so the hook 200B will not rotate due to this frictional force. Through this series of actions, the hook 200B can be moved from the use position P1 to the retracted position P2. It should be noted that by performing the opposite actions to the series of actions described above, the hook 200B can be moved from the retracted position P2 to the use position P1.

[0105] As explained above, according to the second embodiment, for example, if the hook 200B located on the upper surface 10a of the main body 10 becomes an obstacle during binding operations, the hook 200B can be retracted from the upper surface 10a of the main body 10 to the rear surface 10d side, etc. This allows for more efficient operation. It should be noted that in the second embodiment, the first hook mounting part 210 is moved to the rear surface 10d side, but it could also be configured to move to the left side 10b side or the right side 10c side. By moving the hook 200B from the upper surface 10a side of the main body 10, for example, to the left side 10b side, it can be used as a hook for attaching to reinforcing bars S, etc. Alternatively, it could be configured to allow the hook mounting parts located on the left side 10b or right side 10c side of the main body 10 to move to the upper surface 10a side of the main body 10. This allows for separate use of one hook 200B to address various work site conditions, achieving cost reduction compared to using two hooks.

[0106] <Third Implementation Method>

[0107] In the rebar tying machine 1C of the third embodiment, the hook 200C can be retracted to the side of the main body 10 without using the hook 200C. It should be noted that components having substantially the same function as the rebar tying machine 1A of the above embodiments are omitted from repeated description by using the same reference numerals.

[0108] [Structural Example of Rebar Tying Machine 1C]

[0109] Figure 10 This is a perspective view of the rebar tying machine 1C of the third embodiment, viewed from the rear left side. Figure 11A This is a cross-sectional view showing the fastener 520 that connects the hook 200C. Figure 11B This 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.

[0110] The rebar tying machine 1C includes hook mounting parts 510a and 510b, which are positioned at a usable position P1 (see reference) on the upper surface 10a side of the main body 10 of the 200C. Figure 10 The retreat position P2 to the left side 10b and the right side 10c (refer to) Figure 12 The hook 200C in the third embodiment is supported by a moving mechanism. It has a pair of hook parts 202a and 202b that are generally U-shaped (J-shaped). It should be noted that the hook 200C is not necessarily U-shaped; for example, it can be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0111] The hook mounting part 510a mounts the hook component 202a so that it can rotate from the upper surface 10a side of the main body 10 to the left side 10b side. The hook mounting part 510a is, for example, constructed of a flat hinge, and is fastened to the guide surface 250a and the left side 250c of the cover part 250 by screws 512 with the base end of the hook component 202a inserted into its tube.

[0112] The hook mounting part 510b mounts the hook component 202b so that it can rotate from the upper surface 10a side of the main body 10 to the right side surface 10c side. The hook mounting part 510b is, for example, constructed of a flat hinge, and is fastened to the guide surface 250a and the right side surface 250d of the cover part 250 by screws 514 with the base end side of the hook component 202b inserted into its tube.

[0113] Hook mounting parts 510a and 510b are installed in hook 200C, which includes hook parts 202a and 202b, such that the opening 201c into which the reinforcing bar S is inserted faces the front side in the front-rear direction of the main body part 10.

[0114] like Figure 10 and Figure 11A As shown, a fastener 520 with a hook portion on the front end is rotatably mounted on the front end of the hook component 202b constituting the hook 200C. The fastener 520 is inserted into the hook portion of another hook component 202a in a state where the front ends of the hook components 202a and 202b are aligned above the main body 10, thereby connecting (integrating) the front ends of the hook components 202a and 202b.

[0115] Hook 200C is subjected to force by springs 516 and 518 towards the rear of the main body 10. For example... Figure 11B And as will be discussed later Figure 12As shown, a pin 203a is inserted into the hook component 202a of hook 200C, and the pin 203a protrudes. Two slots 511a1 and 511a2 are provided in the hook mounting portion 510a corresponding to the use position P1 and the retracted position P2. Similarly, although a portion of the illustration is omitted, a pin 203b is also inserted into the hook component 202b, and the pin 203b protrudes. Two slots 511b1 and 511b2 are provided in the hook mounting portion 510b. The pins 203a and 203b, inserted into the hook 200C which is stressed by springs 516 and 518, enter slots 511a1 and 511b1 respectively in the use position P1, and slots 511a2 and 511b2 respectively in the retracted position P2, thereby restricting the rotation of hook 200C.

[0116] [Example of the operation of rebar tying machine 1C]

[0117] Figure 12 This is a diagram showing the operation of the rebar tying machine 1C when the hook 200C moves from the working position P1 to the retracted position P2.

[0118] like Figure 11A As shown, in the hook 200C in the use position P1, by rotating the hook portion of the fixing member 520 in the direction away from the hook member 202a, the fixing member 520 disengages from the hook member 202a, and the hook members 202a and 202b are separated.

[0119] Next, as Figure 12 As shown, pushing the hook component 202a forward releases the pin 203a from the groove 511a1, causing it to rotate from the use position P1 on the upper surface 10a side of the main body 10 to the retracted position P2 on the left side 10b side of the main body 10, thereby storing the hook component 202a on the left side 10b side of the main body 10. Because the hook component 202a is subjected to force by the spring 516, the pin 203a enters another groove 511a2 (see reference). Figure 11B The hook component 202b will not rotate from its stored position. Similarly, pushing the hook component 202b forward releases the engagement of the pin 203b with a slot 511b1, causing it to rotate from its operating position P1 on the upper surface 10a side of the main body 10 to its retracted position P2 on the right side 10c side, thereby storing the hook component 202b on the right side 10c side of the main body 10. Because the hook component 202b is subjected to force by the spring 518, the pin 203b enters another slot 511b2 and will not rotate from its stored position.

[0120] As explained above, according to the third embodiment, for example, if the hook 200C located on the upper surface 10a of the main body 10 becomes an obstacle during the binding operation, the hook 200C can be retracted from the upper surface 10a of the main body 10 to the left side 10b, etc. This allows for more efficient operation.

[0121] <Fourth Implementation Method>

[0122] In the rebar tying machine 1D of the fourth embodiment, a hook mounting part 210a, etc., is provided only on the upper surface 10a side of the main body 10. It should be noted that the constituent elements having substantially the same function as the rebar tying machine 1A of the above embodiment are omitted from repeated description by using the same reference numerals.

[0123] Figure 13 This is a perspective view of the rebar tying machine 1D of the fourth embodiment, viewed from the rear left side.

[0124] like Figure 13 As shown, the rebar tying machine 1D includes a main body 10, and a tying part 4 having a coiling forming part 5 and a twisting part 7 is provided at the front end of the main body 10 along its length. A drive part 8 that drives the tying part 4 is housed inside the main body 10 (see reference). Figure 4 The rebar tying machine 1D includes: a material box 2, disposed on the lower surface 10e side of the main body 10 and for storing the binding wire W in a way that allows it to be fed out; a gripping part 11, disposed on the lower surface 10e side of the main body 10 and behind the material box 2; and a plurality of hook mounting parts 210a~210e, located on the upper surface 10a side of the main body 10 and capable of mounting U-shaped hooks 200A with one side opening. In this embodiment, the hooks 200A are configured to have a U-shaped side shape, but they do not necessarily have to be U-shaped; for example, they can also be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0125] The hook mounting portion 210d, etc., is provided along the front-rear direction (length direction) of the guide surface 250a of the cover portion 250. The hook mounting portion 210d, etc., is used to mount the hook 200A in such a way that the opening 201 of the hook 200A faces the front side of the main body portion 10 in the front-rear direction. It should be noted that, as described in the first embodiment, the hook mounting portions 210d, etc., are not limited to five, and any number can be provided. In addition, the hook mounting portions 210d, etc., can also be directly provided on the upper surface 10a of the main body portion 10.

[0126] like Figure 8A As shown, the hook mounting part 210d, etc., can also mount the hook 200A in a manner that allows it to move from the upper surface 10a side of the main body 10 to the rear surface 10d side. Additionally, as... Figure 10 As shown, the hook mounting part 210d and the like can also mount the hook 200A in a manner that allows it to move from the upper surface 10a side of the main body part 10 to at least one of the left side 10b side and the right side 10c side.

[0127] As explained above, since the rebar tying machine 1D of the fourth embodiment has a material box 2 for storing tying wire W and a holding part 11 on the lower surface 10e side of the main body 10, the center of gravity C of the rebar tying machine 1D is located below the main body 10, more specifically near the material box 2. Therefore, when such a rebar tying machine 1D is hooked onto the rebar S, etc. by the hook 200A installed on the hook mounting part 210, due to the relationship with the center of gravity position, the rebar tying machine 1D will not tilt (move) significantly and become unstable, and can be held stably. That is, the rebar tying machine 1D is stably hooked onto the rebar S, etc., so it is not easy for problems such as the rebar tying machine 1D falling off the rebar to occur. Furthermore, since the hook mounting part 210 mounts the hook 200A to the upper surface 10a side of the main body 10 with the opening 201 of the hook 200A facing forward, when the hook 200A is mounted to the hook mounting part 210, after tying the rebar S located in front of the operator, it is possible to hook the rebar S with less movement without tilting the front end of the main body 10 containing the curling forming part 5 downwards and flipping the wrist. Therefore, when repeatedly using the rebar tying machine 1D and hooking it when not in use, work efficiency is increased and the operator's workload is reduced.

[0128] <Fifth Implementation Method>

[0129] In the fifth embodiment of the rebar tying machine 1E, a hook mounting part 310 is provided only on the left side 10b of the main body 10. It should be noted that components having substantially the same function as the rebar tying machine 1A of the above embodiment are omitted from repeated description by using the same reference numerals.

[0130] Figure 14 This is a perspective view of the rebar tying machine 1E of the fifth embodiment, viewed from the rear left side.

[0131] like Figure 14 As shown, the rebar tying machine 1E includes a main body 10, and a tying part 4 having a coiling forming part 5 and a twisting part 7 is provided at the front end of the main body 10 along its length. A drive part 8 that drives the tying part 4 is housed inside the main body 10 (see reference). Figure 4 The rebar tying machine 1E includes: a material box 2, disposed on the lower surface 10e side of the main body 10 and for storing the binding wire W in a way that allows it to be fed out; a gripping part 11, disposed on the lower surface 10e side of the main body 10 and behind the material box 2; and a hook mounting part 310, located on the left side 10b side of the main body 10 and capable of mounting a U-shaped hook 300 with an opening on one side. In this embodiment, the hook 300 is configured to have a U-shaped side profile, but it does not necessarily have to be U-shaped; for example, it can also be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0132] The hook mounting part 310 is provided in the protrusion 250e of the cover 250. The hook mounting part 310 is such that the opening 301 of the hook 300 faces the center of gravity C of the rebar tying machine 1E (see reference). Figure 3 The hook 300 is installed in a manner described above. Furthermore, the hook mounting part 310 installs the hook 300 such that the opening 301 of the hook 300 faces the lower side in the vertical direction of the main body part 10. It should be noted that, as... Figure 7 As shown, multiple hook mounting portions 310 can be provided, or they can be directly provided on the left side 10b of the main body 10. In addition, the hook mounting portion 310 can also be provided on the right side 10c of the main body 10, or on both the left side 10b and the right side 10c.

[0133] As explained above, since the rebar tying machine 1E of the fifth embodiment has a material box 2 for storing tying wire W and a holding part 11 on the lower surface 10e side of the main body 10, the center of gravity C of the rebar tying machine 1E is located below the main body 10, more specifically near the material box 2. Therefore, when such a rebar tying machine 1E is hooked onto the rebar S, etc. by the hook 300 installed on the hook mounting part 310, due to the relationship with the center of gravity position, the rebar tying machine 1E will not tilt (move) significantly and become unstable, and can be held stably. That is, the rebar tying machine 1E is stably hooked onto the rebar S, etc., so it is not easy for problems such as the rebar tying machine 1E falling off the rebar S, etc. to occur. Furthermore, since the hook mounting part 310 mounts the hook 300 on the left side 10b of the main body 10 with the opening 301 of the hook 300 facing downwards, when the rebar tying machine 1E is attached to 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. Therefore, the amount of protrusion of the main body 10 relative to the rebar S is reduced, and even when the rebar tying machine 1E is attached, it does not hinder operation, allowing for smooth movement and operation at the work site.

[0134] <Sixth Implementation Method>

[0135] The rebar tying machine 1F of the sixth embodiment differs from the rebar tying machine 1A of the first embodiment in that a material box 2 is provided on the side of the main body 10. It should be noted that components having substantially the same function as the rebar tying machine 1A of the above embodiments are omitted from repeated description by using the same reference numerals.

[0136] Figure 15 This is a perspective view of the rebar tying machine 1F of the sixth embodiment, viewed from the rear right side.

[0137] like Figure 15As shown, the rebar tying machine 1F includes a main body 10, and a tying section 4 having a coiling forming section 5 and a twisting section 7 is provided at the front end of the main body 10 along its length. A drive section 8 that drives the tying section 4 is housed inside the main body 10 (see reference). Figure 4 ) (refer to Figure 4 The rebar tying machine 1F includes: a material box 2, which is located at the rear end of the main body 10 in the front-rear direction and stores the tying wire W in a way that allows it to be fed out; and a holding part 11, which is located on the lower surface 10e side of the main body 10.

[0138] Furthermore, the rebar tying machine 1F includes a first hook mounting portion 210 located on the upper surface 10a side of the main body 10 and capable of mounting a U-shaped first hook 200A with an opening on one side. In this embodiment, the first hook 200A is configured to have a U-shaped side profile, but it does not necessarily have to be U-shaped; for example, it could be J-shaped, L-shaped, U-shaped, or crank-shaped.

[0139] The material box 2 is located on the right side 10c of the main body 10 to avoid the torsion part 7 and drive part 8 located on the left side of the main body 10. The material box 2 is composed of a space that can hold a spool wound with binding wire W.

[0140] In addition, such as Figure 15 As shown, a material box cover 22 is provided on the rear side of the main body 10, which is capable of opening and closing the material box 2. The material box cover 22 is mounted on a support shaft 24 provided on the upper surface 10a of the main body 10, and is configured to be able to rotate about the support shaft 24 as a fulcrum to the position of closing the material box 2 and the position of opening the material box 2.

[0141] A first hook mounting portion 210 is provided on the upper surface of the material box cover portion 22. The first hook mounting portion 210 mounts the first hook 200A such that the opening 201 of the first hook 200A faces the front side in the front-rear direction of the main body portion 10. The first hook 200A is mounted via a locking piece 202 (see reference). Figure 2 The screw 206 is inserted into the engaging hole 212 formed in the material box cover portion 22 and passes through the insertion hole 204 (see reference). Figure 2 It is screwed into the threaded hole 214 formed in the material box cover 22 and installed on the material box cover 22.

[0142] It should be noted that, as described in the first embodiment, multiple first hook mounting portions 210 may be provided, or they may be directly provided on the upper surface 10a of the main body portion 10. Furthermore, as... Figure 8A As shown, the first hook mounting portion 210 can also mount the first hook 200A in a manner that allows it to move from the upper surface 10a side of the main body portion 10 to the rear surface 10d side. Furthermore, as... Figure 10As shown, the first hook mounting part 210 can also mount the first hook 200A in a manner that allows it to move from the upper surface 10a side of the main body part 10 to at least one of the left side 10b side and the right side 10c side.

[0143] Alternatively, as described in the first embodiment, the 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 mounts the second hook 300 in such a way that it does not obstruct the opening 201 of the first hook 200A mounted on the first hook mounting portion 210 when the main body portion 10 is viewed from the front. In addition, the second hook mounting portion 310 mounts the second hook 300 in such a way that the second hook 300 does not protrude from the upper surface 10a of the main body portion 10 or the material box cover portion 22.

[0144] Furthermore, the second hook mounting part 310 mounts the second hook 300 such that the opening 301 of the second hook 300 faces downward in the front-rear direction of the rebar tying machine 1F and towards the center of gravity D of the rebar tying machine 1F. Here, the center of gravity D of the rebar tying machine 1F is determined by the weight and arrangement of the main body 10, the coiling forming part 5, the material box 2, the handle part 11, the battery 15, etc. In this embodiment, since the material box 2, which is one of the weights, is located at the rear end of the main body 10 in the front-rear direction, the connection between the lower surface 10e of the main body 10 and the upper end of the handle part 11 is located slightly behind the trigger 12.

[0145] As explained above, since the rebar tying machine 1F of the sixth embodiment has a material box 2 at the rear end of the main body 10 in the front-rear direction, the center of gravity D of the rebar tying machine 1F is located near the material box 2. Therefore, when such a rebar tying machine 1F is hooked onto the rebar S, etc. via the hook 200A installed on the hook mounting part 210, due to the relationship with the center of gravity position, the rebar tying machine 1F will not tilt (move) significantly and become unstable, and can be held stably. That is, the rebar tying machine 1F is stably hooked onto the rebar S, etc., so it is not easy for problems such as the rebar tying machine 1F falling off the rebar S, etc. to occur.

[0146] Furthermore, according to the rebar tying machine 1F, since the hook mounting part 210 mounts the hook 200A to the upper surface 10a side of the main body 10 with the opening 201 of the hook 200A facing forward, when the hook 200A is mounted on the hook mounting part 210, after tying the rebar S or the like located in front of the operator, it is possible to hook the rebar S or the like with less movement without tilting the front end of the main body 10, which has the curling forming part 5, etc., downward while flipping the wrist. Therefore, when repeatedly using the rebar tying machine 1F and hooking it when not in use, work efficiency is increased and the operator's workload is reduced.

[0147] The above is with reference to the appendix. Figure 1 The preferred embodiments of this disclosure have been described in detail, but the technical scope of this disclosure is not limited to these examples. For example, in the above embodiments, the case where the tool is a rebar tying machine 1A or the like has been described, but as tools, in addition to the rebar tying machine 1A or the like, nailing machines and screw tightening machines can also be used, and the hook mounting part described above can also be applied to nailing machines and screw tightening machines.

[0148] In the above embodiments, the first hook mounting portion 210a is formed by the engaging hole 212a into which the engaging piece 202 of the first hook 200A is inserted and the threaded hole 214a into which the screw 206 is screwed. However, the structure is not limited to these structures. For example, known fastening methods such as embedded fastening can be used instead of threaded fastening. Furthermore, the same applies to other second hook mounting portions 310 described in the above embodiments.
