[0006] [Patent Document 1] Japanese Patent Application Publication No. 2023-41539 Summary of the Invention

[0007] [The problem the invention aims to solve]

[0008] However, in work sites where reinforcement work is carried out on walls, columns, etc., and where the reinforced steel bars are tied with wire, there are advantages in terms of work efficiency when hooking the reinforced steel bars to the next tying work compared to placing tools such as steel bar tying machines that are not currently in use on the scaffold.

[0009] In the binding machine described in Patent Document 1, the opening of the hook installed in the second hook mounting part faces the center of gravity of the binding machine. Therefore, when the binding machine is hooked onto the reinforcing bar using this hook, the orientation of the binding machine will not change significantly even if the hand leaves the binding machine.

[0010] However, when the user of the strapping machine uses a hook to attach the strapping machine to the rebar, and then holds the strapping machine again to use it, the way the tool is used varies from user to user, and it is necessary to be able to accommodate the various usage methods of each user.

[0011] The present invention was made to solve such a problem, and its purpose is to provide a tool that is equipped with a hook that can be hooked onto a fixed object, and a cover that is equipped with a hook that can be hooked onto a fixed object and can be attached and detached relative to the tool, corresponding to various usage methods of each user.

The tool cover has a locking part that is set at different angles toward the center of gravity of the tool, and is capable of locking an object. The locking part is provided on the cover.

[0015] Furthermore, the present invention provides a tool locking body that, compared to a locking part provided in the main body of a tool having a main body and a gripping part connected to the main body, and capable of locking an object via the locking body, can be mounted towards the center of gravity of the tool. Additionally, the present invention provides a tool locking body that, compared to a locking part provided in a cover of a tool having a main body and a gripping part connected to the main body, and capable of locking an object via the locking body, can be mounted towards the center of gravity of the tool.

[0016] In this invention, the locking body, which can lock onto the object being locked, is installed at different angles toward the center of gravity of the tool.

[0017] [Invention Effects]

[0018] In this invention, a locking body that can be hooked onto a locking object can be installed at different angles toward the center of gravity of the tool, corresponding to various usage methods of each user.

[0045] Hereinafter, with reference to the accompanying drawings, an example of a rebar tying machine as an embodiment of the tool of the present invention, and an example of a tool cover and tool clamping body installed on the rebar tying machine will be described.

[0046] <Structural Example of the Rebar Binding Machine in This Embodiment>

[0047] Figure 1A This is a side view showing an example of the rebar tying machine according to this embodiment, viewed from one side. Figure 1B This is a perspective view taken from one side, showing an example of the rebar tying machine according to this embodiment. Additionally, Figure 2A This is a side view showing an example of the rebar tying machine of this embodiment, viewed from the other side. Figure 2B This is a perspective view taken from the other side, showing an example of the rebar tying machine of this embodiment.

[0048] The rebar tying machine 1A is a handheld type, which has a main body 10 and a handle 10H connected to the main body 10 as a gripping part.

[0049] The rebar tying machine 1A has a working section 10W formed on one side of the main body 10 along the extending direction, as indicated by arrow B, for tying the rebar S, which is the object of the work. The side of the rebar tying machine 1A that forms the working section 10W relative to the extending direction of the main body 10 is called the front side, and the side opposite to the side that forms the working section 10W is called the rear side.

[0050] Furthermore, the handle portion 10H of the rebar tying machine 1A extends in a direction intersecting the extending direction of the main body portion 10. That is, the extending direction of the handle portion 10H, as indicated by arrow C of the rebar tying machine 1A, intersects the extending direction of the main body portion 10. The side on which the handle portion 10H is formed is referred to as the lower side (one side) of the rebar tying machine 1A, and the side opposite to the side on which the handle portion 10H is formed is referred to as the upper side (the other side).

[0051] The rebar tying machine 1A has a locking part capable of locking the rebar S or the like as a locking object. The locking part can lock the locking object directly or indirectly. In this embodiment, a form capable of indirectly locking the locking object is shown, and the locking part is equipped with a hook 11 that can hook the rebar tying machine 1A onto the rebar S. The hook 11 is an example of a locking body or a tool locking body, and the end of the hook 11 extending in the direction indicated by arrow D has a locking part 11a capable of locking with the rebar S.

[0052] The rebar tying machine 1A has multiple hook mounting portions 12 arranged at different angles toward the center of gravity G of the rebar tying machine 1A. The hook mounting portions 12 are examples of locking portions, enabling the hooks 11 to be mounted at different angles toward the center of gravity G of the rebar tying machine 1A. In the above, "able to be mounted at different angles" means that the locking body is fixedly mounted relative to the locking portion at a predetermined angle. Furthermore, "fixed" means that some relative displacement is permissible, indicating a degree of fixation that does not affect the locking function.

[0053] The hook mounting portion 12 can be provided on at least one side of the rear side of the main body 10. Here, "side" refers to a surface parallel to the extending direction of the main body 10. It is preferable to provide the hook mounting portion 12 on the side of the main body 10, that is, when positioned apart from the handle portion 10H, it is difficult for the operator's hand, gripping the handle portion 10H, to come into contact with the reinforcing bar S, which is the object to be secured. The hook mounting portion 12 provided on the side of the main body 10 can mount the hook 11 such that, when viewed from the side, the secured portion 11a faces the center of gravity G of the reinforcing bar binding machine 1A. In a structure having multiple hook mounting portions 12, at least one hook mounting portion 12 can mount the hook 11 such that, when viewed from the side, the secured portion 11a faces the center of gravity G of the reinforcing bar binding machine 1A.

[0054] The hook mounting portion 12 can be oriented toward the hook 11 with the extension direction of the hook 11 intersecting the extension direction of the handle portion 10H. In a structure having multiple hook mounting portions 12, at least one hook mounting portion 12 can be oriented toward the hook 11 with the extension direction of the hook 11 intersecting the extension direction of the handle portion 10H.

[0055] Furthermore, the hook mounting portion 12 can mount the hook 11 such that the locking portion 11a is located further rearward in the extension direction of the handle portion 10H. Moreover, the hook mounting portion 12 can mount the hook 11 such that at least a portion of the locking portion 11a is located further rearward than the rear end Bp of the main body portion 10. In a structure having multiple hook mounting portions 12, at least one hook mounting portion 12 can mount the hook 11 such that at least a portion of the locking portion 11a is located further rearward than the rear end Bp of the main body portion 10.

[0056] Figure 3 This is a perspective view showing an example of a hook. The hook 11 includes: a supported portion 11b, which can be fixedly supported on the hook mounting portion 12; an extension portion 11c, which has a predetermined size for connecting the supported portion 11b and the locking portion 11a; and a locking protrusion 11d, which prevents the hook 11 from disengaging from the locking object.

[0057] The extension 11c of the hook 11 extends from the supported portion 11b. The locking portion 11a is formed at the top of the extension 11c. The locking protrusion 11d extends from the locking portion 11a along the extension 11c toward the supported portion 11b. An opening of a size that allows an object to be inserted is formed between the locking protrusion 11d and the extension 11c of the hook 11 by means of a steel bar S, etc.

[0058] In this example, the extension 11c includes a first extension 11c1 and a second extension 11c2. The first extension 11c and the second extension 11c extend parallel to each other. Additionally, the locking portion 11a in this example includes a first locking portion 11a and a second locking portion 11a. The first locking portion 11a is connected to the first extension 11c, and the second locking portion 11a is connected to the second extension 11c. The arrangement direction of the first locking portion 11a and the second locking portion 11a of the hook 11 is orthogonal to the extension direction of the hook 11. Furthermore, the arrangement direction of the first locking portion 11a and the second locking portion 11a may not be orthogonal to the extension direction of the hook 11, as long as it can lock the object being locked.

[0059] The supported portion 11b has a fastening portion 11e for fastening screws 14. The fastening portion 11e is an example of a fixing portion, and in this example, it is formed by an internal thread penetrating the plate-shaped supported portion 11b. In order to be fixed to the hook mounting portion 12 by multiple screws 14, the hook 11 may also have multiple fastening portions 11e. In this example, the supported portion 11b has two fastening portions 11e. It should be noted that the support shape, the number and position of the fastening parts, and the support mechanism (fastening) can be appropriately modified as long as they can be locked to the object being locked.

[0060] Figure 4This is a perspective view showing an example of a hook mounting portion. The hook mounting portion 12 includes a support portion 12a capable of supporting the supported portion 11b and a hole portion 12b for inserting a screw 14.

[0061] The support portion 12a has a predetermined shape that matches the shape of the supported portion 11b, and is composed of a recess into which the supported portion 11b can be inserted. Thus, the support portion 12a is configured such that the mounting position and orientation of the hook 11 can be determined by inserting it into the supported portion 11b. Furthermore, when fixing the hook 11, the supported portion 11b is positioned with its portion inserted into the support portion 12a, which can fix the hole portion 12b and the fastening portion 11e. Therefore, the hook will not fall significantly from its fixed position, and the hook 11 can be easily fixed to the hook mounting portion 12. The orientation of the hook 11 refers to the orientation of the extension direction of the hook 11, that is, the orientation of the extension direction of the extension portion 11c.

[0062] The hole 12b is provided on the support portion 12a in a configuration that matches the fastening portion 11e of the hook 11. To specify the orientation of the hook 11, the hook mounting portion 12 may also have multiple holes 12b. Furthermore, to allow the mounting position of the hook 11 to be variable, the hook mounting portion 12 may also have multiple rows of holes 12b. In this example, two rows of holes 12d on the hook mounting portion 12, which match the configuration of the two fastening portions 11e, are provided at a predetermined interval.

[0063] In this example, the rebar tying machine 1A has hook mounting parts 12L1, 12L2, 12L3, 12R1, 12R2, and 12R3 at three locations on each side of the main body 10. In addition, the rebar tying machine 1A has a hook mounting part 12U at one location on the upper surface of the main body 10.

[0064] When hook 11 is installed on hook mounting parts 12L1, 12L2, 12L3, 12R1, 12R2, and 12R3, the shape and orientation of support parts 12a and hole parts 12b are specified in such a way that when the locking part 11a is viewed from the side of the rebar tying machine 1A, the direction of the center of gravity G of the rebar tying machine 1A is oriented.

[0065] Each hook mounting part 12 can also be a structure that is installed on a cover 15 that can be installed and removed relative to the rebar tying machine 1A.

[0066] Figure 5 This is an exploded perspective view showing an example of the rebar tying machine according to this embodiment, after the cover has been disassembled. Figure 6A , Figure 6B , Figure 6C , Figure 6D This is a three-dimensional diagram representing an example of a cover. Additionally, Figure 7A This is a side view showing an example of the rebar tying machine of this embodiment without the hook installed, as viewed from one side. Figure 7B yes Figure 7AA sectional view along line AA. Furthermore... Figure 8 This is a perspective view of a rebar tying machine, illustrating an example of a hook installation method.

[0067] Cover 15 is an example of a tool cover, having a first cover portion 15L and a second cover portion 15R. The first cover portion 15L is configured to cover one side of the rear side of the main body portion 10, and the second cover portion 15R is configured to cover the other side of the rear side of the main body portion 10.

[0068] The first cover portion 15L has a positioning portion 15La on its inner surface opposite one side of the main body portion 10. The second cover portion 15R has a positioning portion 15Ra on its inner surface opposite the other side of the main body portion 10.

[0069] Due to its internal structure, appearance, and the presence of screw holes for screw insertion, the main body 10 has irregularities in its shape, with an irregularity 10La formed on one side. Similarly, an irregularity 10Ra is formed on the other side of the main body 10.

[0070] The positioning part 15La is configured with a concave-convex shape that mates with the concave-convex part 10La on one side of the main body part 10. The positioning part 15Ra is configured with a concave-convex shape that matches the concave-convex part 10Ra on the other side of the main body part 10.

[0071] The first cover portion 15L has a hole portion 15Lb for inserting a screw 16. The second cover portion 15R has a fastening portion 15Rb for fastening the screw 16. The screw 16, the hole portion 15Lb, and the fastening portion 15Rb are an example of a connecting part.

[0072] The first cover portion 15L covers one side of the rear of the main body portion 10 by aligning the positioning portion 15La with the concave and convex portions 10La of the main body portion 10, thereby covering one side of the rear of the main body portion 10 in a position predetermined relative to the main body portion 10. Similarly, the second cover portion 15R covers one side of the rear of the main body portion 10 by aligning the positioning portion 15Ra with the concave and convex portions 10Ra of the main body portion 10, thereby covering one side of the rear of the main body portion 10 in a position predetermined relative to the main body portion 10.

[0073] The cover 15 covers one side of the rebar tying machine 1A with a first cover portion 15L and the other side of the rebar tying machine 1A with a second cover portion 15R, thereby aligning the positions of the hole portion 15Lb and the fastening portion 15Rb. Furthermore, the cover 15 is fastened to the fastening portion 15Rb by screws 16 inserted into the hole portion 15Lb, thereby making the first cover portion 15L and the second cover portion 15R integral and fixed to the rebar tying machine 1A.

[0074] In the cover 15, the positioning part 15La of the first cover part 15L is embedded in the concave-convex part 10La on one side of the main body part 10, and the positioning part 15Ra of the second cover part 15R is embedded in the concave-convex part 10Ra on the other side of the main body part 10. Thus, the cover 15 is prevented from accidentally moving relative to the rebar tying machine 1A or accidentally detaching from the rebar tying machine 1A.

[0075] Furthermore, the first cover portion 15L and the second cover portion 15R of the cover 15 are matched with the outer shape of the main body portion 10 of the existing rebar tying machine 1A to form positioning portions 15La and 15Ra. As a result, the hook mounting portion 12 can be installed in the existing rebar tying machine 1A that does not have a hook mounting portion 12 by using the cover 15.

[0076] Furthermore, the cover 15 covers the main body 10 while the handle portion 10H is exposed. Therefore, when holding the handle portion 10H, the cover 15 is prevented from becoming an obstacle to gripping. It should be noted that in this example, the rebar tying machine 1A has an operating section 9 (described later) at the rear end of the main body 10. Therefore, the cover 15 is shaped with an opening at the rear end to expose the operating section 9.

[0077] In order to install the hook 11 onto the hook mounting part 12, the supported part 11b of the hook 11 is inserted into the support part 12a. When the supported part 11b is inserted into the support part 12a, the orientation of the hook 11 relative to the main body part 10 is determined by the shape of the support part 12a and the supported part 11b, etc.

[0078] Furthermore, by aligning the position of the fastening part 11e with the hole part 12b and fastening the screw 14 inserted into the hole part 12b to the fastening part 11e, the hook 11 is fixed to the hook mounting part 12 in a state where the orientation relative to the main body part 10 is specified.

[0079] Furthermore, by aligning the position of the fastening part 11e with the hole part 12b of the first row or the hole part 12b of the second row, and fastening the screw 14 inserted into the hole part 12b to the fastening part 11e, the position of the locked part 11a along the extension direction of the hook 11 is switched.

[0080] Figure 9 This is a side view of the internal structure of the rebar tying machine according to this embodiment, showing an example of its overall structure. The rebar tying machine 1A feeds wire W in the positive direction (indicated by arrow F) and winds it around the rebar S, which is the object to be tied. Then, it feeds the wire W wound around the rebar S in the opposite direction (indicated by arrow R) and winds it around the rebar S again. The wire W is then twisted to tie the rebar S. The rebar tying machine 1A uses multiple wires W (two wires W in this example) to tie the rebar S. It should be noted that the rebar tying machine 1A could also be a structure that uses only one wire W to tie the rebar S.

[0081] To achieve the aforementioned functions, the rebar tying machine 1A includes a hopper 2 for storing wire W, a wire conveying section 3 for conveying the wire W, and a wire guide 4 for guiding the wire W conveyed towards the wire conveying section 3. Furthermore, the rebar tying machine 1A includes a coiling forming section 5, which forms a circular conveying path for winding the wire W conveyed by the wire conveying section 3 around the rebar S; and a cutting section 6, which cuts the wire W wound around the rebar S. Moreover, the rebar tying machine 1A includes a tying section 7 for twisting the wire W wound around the rebar S and a drive section 8 for driving the tying section 7. Additionally, the rebar tying machine 1A includes an operating section 9 capable of setting the tying force for twisting and tying the wire W.

[0082] The hopper 2 is an example of a storage unit, which stores a spool 20 wound into a long strip shape for unwinding in a rotatable and detachable manner. The wire W is an example of a consumable. The wire W is made of a metal wire that can be plastically deformed, a metal wire coated with resin, or a stranded wire. In a structure that uses two wires W to bind the reinforcing bar S, the spool 20 winds two wires W, and both wires W are pulled out from the spool 20 simultaneously.

[0083] The wire conveying unit 3 includes a pair of conveying gears 30 that clamp and convey the wire W. The wire conveying unit 3 transmits the rotational motion of a conveying motor (not shown) to the conveying gears 30, causing the conveying gears 30 to rotate. Furthermore, the wire conveying unit 3 switches the rotation direction of the conveying gears 30 by switching the rotation direction of the conveying motor (not shown), thereby switching the forward and reverse conveying direction of the wire W. In the structure using two wires W to bind the reinforcing bar S, the wire conveying unit 3 conveys the two wires W radially.

[0084] The wire guide 4 is positioned upstream of the conveying gear 30 and downstream (not shown) relative to the conveying direction of the wire W being conveyed in the positive direction. In the structure that uses two wires W to tie the reinforcing bar S, the wire guide 4 guides the two incoming wires W side by side along the arrangement direction of the pair of conveying gears 30 and between the pair of conveying gears 30.

[0085] The curling forming unit 5 includes a curling guide 50 that forms curl lines on the wire W fed by the wire feed unit 3, and a guide 51 that guides the wire W, which has formed curl lines on the curling guide 50, to the bundling unit 7. The curling forming unit 5 forms a loop conveying path Ru, shown by a double-dotted line, from the curling guide 50 to the bundling unit 7 by curling the wire W conveyed by the wire conveying unit 3 and passing through the curling guide 50.

[0086] The cutting unit 6 includes a fixed blade 60, a movable blade 61 that cuts the wire W in cooperation with the fixed blade 60, and a transmission mechanism 62 that transmits the movement of the binding unit 7 to the movable blade 61. The cutting unit 6 cuts the wire W by rotating the movable blade 61 with the fixed blade 60 as the fulcrum.

[0087] The binding section 7 includes a wire clamping body 70 for clamping the wire W and a sleeve 71 for operating the wire clamping body 70. The drive section 8 includes a torsion motor 80 and a reducer 81 for deceleration and torque amplification.

[0088] In the rebar tying machine 1A, the curling guide 50 and the guide guide 51 of the curling forming section 5 are provided at the front end of the main body section 10. The curling forming section 5 constitutes the working section 10W.

[0089] The rebar tying machine 1A has a trigger 10T on the front side of the handle 10H and a switch 10S inside the handle 10H. The rebar tying machine 1A controls the feed motor and the torsion motor 80 by a control unit (not shown) according to the state of the switch 10S pressed by the operation of the trigger 10T.

[0090] The rebar tying machine 1A has a battery mounting section 10B at the lower part of the handle 10H. The battery mounting section 10B can detachably mount a battery 100.

[0091] The feed hopper 2 of the rebar tying machine 1A is located in front of the handle 10H. Furthermore, the rebar tying machine 1A houses the aforementioned wire feed section 3, cutting section 6, tying section 7, and drive section 8 for driving the tying section 7 within the main body 10. The torsion motor 80 is housed within the rear end of the main body 10.

[0092] The operation unit 9 includes an operation dial 90, etc. The operation unit 9 is located at the rear end of the main body 10.

[0093] The center of gravity G of the rebar tying machine 1A is the center of gravity when the rebar tying machine 1A is in use, with the spool 20 containing the wire W stored in the hopper 2 and the battery 100 installed in the battery mounting section 10B. Figure 1A The center of gravity G shown is the position of the center of gravity when the reel 20, with a specified amount of wire W wound on it, is stored in the hopper 2. The rebar tying machine 1A consumes wire W during the action of tying the rebar S, thus reducing the amount of wire W wound on the reel 20. Therefore, although the weight of the reel 20 changes, the center of gravity G of the rebar tying machine 1A is approximately located between the handle 10H and the hopper 2.

[0094] <Examples of how hooks are used>

[0095] Figure 10A , Figure 10BThis is an illustrative diagram showing an example of how a hook is used. For example... Figure 2A , Figure 2B As shown, when the hook 11 is installed in the hook mounting part 12R, the extension direction of the hook 11 intersects the extension direction of the handle part 10H, and the locking part 11a is located further back than the extension line of the extension direction of the handle part 10H and further back than the rear end Bp of the main body part 10. Furthermore, when the rebar tying machine 1A is viewed from the side, the locking part 11a is oriented towards the center of gravity G of the rebar tying machine 1A.

[0096] When the reinforcement bar S is erected vertically, consider the action of using hook 11 to hook the reinforcement bar binding machine 1A onto the reinforcement bar S.

[0097] The rebar tying machine 1A is used by holding the handle 10H by hand and operating the trigger 10T with the fingers of the hand holding the handle 10H. Therefore, the user of the rebar tying machine 1A is in a configuration where the handle 10H is held by extending the arm from the rear of the main body 10.

[0098] With the user holding the handle 10H with their right hand, during the action of hooking the hook 11 onto the laterally extending steel bar S, the user... Figure 10A The rebar tying machine 1A is viewed from the left side, as shown in the diagram. With the hook 11 installed in the hook mounting part 12R1, the hook 11 is installed on the side opposite to the side of the main body 10 that can be visually confirmed. However, since the locking part 11a is located further back than the rear end Bp of the main body 10, the user can easily detect it from the side. Figure 10A When viewing the rebar tying machine 1A from the left side (as shown in the diagram), the clamping part 11a is also visible. Therefore, the clamping part 11a can be easily and reliably aligned with the position of the rebar S.

[0099] Furthermore, since the extension direction of hook 11 is perpendicular to the extension direction of handle 10H, hook 11 can be hooked onto steel bar S without significantly changing the orientation of the wrist.

[0100] Furthermore, since the locking part 11a is oriented towards the center of gravity G of the rebar tying machine 1A, the orientation of the rebar tying machine 1A does not change significantly when the hook 11 is hooked onto the rebar S and the hand is removed from the handle part 10H. Therefore, the rebar tying machine 1A can be reliably hooked onto the rebar S using the hook 11. Additionally, when gripping the handle part 10H again, there is no need to drastically change the orientation of the wrist. This allows for various usage methods to be accommodated by each user.

[0101] The hook 11 is fixed to the hook mounting portion 12 by screws 14, which serve as other fixing parts, with its orientation relative to the main body portion 10 defined by the shapes of the supporting portion 12a and the supported portion 11b. By fixing the hook 11 to the hook mounting portion 12 with at least two fixing parts in this way, accidental changes in orientation are prevented.

[0102] In addition, the cover 15 is made of resin and the hook 11 is made of metal.

[0103] Figure 11A , Figure 11B , Figure 12A , Figure 12B This is a side view of a rebar tying machine showing an example of hook installation. Figure 11A , Figure 11B This is a side view of the rebar tying machine 1A, viewed from one side. Figure 12A , Figure 12B This is a side view of the rebar tying machine 1A viewed from the other side.

[0104] exist Figure 11A In the main body 10, hook 11 is mounted on hook mounting part 12L2. When viewed from the side, the hook 11 mounted on hook mounting part 12L2 is mounted on the main body 10 at a different angle to the center of gravity G of the rebar tying machine 1A, relative to the hook 11 mounted on hook mounting part 12L1. When viewed from the side, the locking part 11a of hook 11 mounted on hook mounting part 12L2 faces the center of gravity G.

[0105] exist Figure 11B In the rebar tying machine 1A, when viewed from the side, hook 11 is mounted on hook mounting part 12L3. Hook 11 mounted on hook mounting part 12L3 is mounted on main body part 10 at a different angle towards the center of gravity G of rebar tying machine 1A, relative to hook 11 mounted on hook mounting parts 12L1 and 12L2. When viewed from the side, the locking part 11a of hook 11 mounted on hook mounting part 12L3 faces the center of gravity G.

[0106] exist Figure 12A In the main body 10, hook 11 is mounted on hook mounting part 12R2. When viewed from the side, the hook 11 mounted on hook mounting part 12R2 is mounted on the main body 10 at a different angle to the center of gravity G of the rebar tying machine 1A, relative to the hook 11 mounted on hook mounting part 12R1. When viewed from the side, the locking part 11a of hook 11 mounted on hook mounting part 12R2 is oriented towards the center of gravity G.

[0107] exist Figure 12BIn the rebar tying machine 1A viewed from the side, hook 11 is mounted on hook mounting part 12R3. Hook 11 mounted on hook mounting part 12R3 is mounted on main body part 10 at a different angle towards the center of gravity G of rebar tying machine 1A, relative to hook 11 mounted on hook mounting part 12R1 and hook 11 mounted on hook mounting part 12R2. When viewed from the side, the locking part 11a of hook 11 mounted on hook mounting part 12R3 faces the center of gravity G.

[0108] Figure 13 This is a top view of a rebar tying machine showing an example of hook installation. Figure 13 In the middle, hook 11 is installed on hook mounting part 12U. Hook 11 installed on hook mounting part 12U is installed on main body part 10 at a different angle toward the center of gravity G of rebar binding machine 1A via cover 15, relative to hook 11 installed on other hook mounting parts 12.

[0109] Figure 14A , Figure 14B These are illustrations showing other examples of how to use a hook. For example... Figure 13 As shown, when the hook 11 is installed in the hook mounting part 12U, the locking part 10a does not face the center of gravity G of the rebar tying machine 1A. However, when the hook 11 installed in the hook mounting part 12U is hooked onto the rebar S, the upper surface of the main body 10 is in contact with the rebar S, and the orientation of the rebar tying machine 1A does not change significantly even if the hand is removed from the handle part 10H. At this time, the handle part 10H extends in a direction intersecting the surface where the rebar S is positioned. Thus, it can accommodate various usage methods of each user.

[0110] Furthermore, the structure in which the multiple hook mounting portions 12 are each formed with a hole 12b has been described, but the hole 12b can also be configured in a manner that allows the multiple hook mounting portions 12 to be used interchangeably.

[0111] <Other structural examples of the rebar tying machine in this embodiment>

[0112] Figure 15 This diagram shows another example of a hook as a locking element. The hook 21, as a locking element, includes: a supported portion 21b, capable of being supported on the hook mounting portion 12; an extension portion 21c, connecting the supported portion 21b and the locking portion 21a, having a predetermined size; and a locking protrusion 21d, preventing the hook 21 from disengaging from the object being locked. Furthermore, the locking portion 21a is a portion extending in the front-to-back direction of the paper, and is connected to... Figure 3 Same shape.

[0113] The extension 21c of hook 21 extends from the supported portion 21b. The locking portion 21a is formed at the top of the extension 21c. The locking protrusion 21d extends from the locking portion 21a along the extension 21c toward the supported portion 21b. An opening of a size that allows an object to be inserted is formed between the locking protrusion 21d and the extension 21c of hook 21 by means of a steel bar S, etc.

[0114] The extension 21c has multiple directional portions. In this example, it has a first directional portion 21c' and a second directional portion 21c' whose extension direction is different from that of the first directional portion 21c', extending from the supported portion 21b toward the locked portion 21a. The first directional portion 21c' and the second directional portion 21c' respectively include a first extension 21c'1 and a second extension 21c'2 of the first directional portion 21c' having a predetermined size, and a first extension 21c''1 and a second extension 21c''2 of the second directional portion 21c' having a predetermined size. The extensions 21c'1, 21c”1 and the second extensions 21c'2, 21c”2 extend parallel to each other. Furthermore, the locking portion 21a in this example includes a first locking portion 21a1 and a second locking portion 21a2. The first locking portion 21a is connected to the first extension 21c”1 of the second direction portion, and the second locking portion 21a is connected to the second extension 21c”2 of the second direction portion. The orientation of the first locking portions 21a1 and the second locking portions 21a2 of the hook 21 is orthogonal to the extension direction of the second direction portion 21c”. Furthermore, the orientation of the first locking portion 21a and the second locking portion 21b may not be orthogonal to the extension direction of the second direction portion 21c”, as long as it can lock onto the object being locked. In addition, it is described that the extension portion has two direction portions with different extension directions, namely the first direction portion and the second direction portion, but the extension portion may also have three or more direction portions with different extension directions. Furthermore, the dimensions of the extension direction of each direction portion may be different. In addition, the dimensions of the extension portions in the direction orthogonal to the extension direction of each direction portion may be the same or different.

[0115] The supported portion 21b has a fastening portion 21e for fastening screws 14. The fastening portion 21e is an example of a fixing portion, and in this example, it is formed by an internal thread penetrating the plate-shaped supported portion 21b. The hook 21 may also have multiple fastening portions 21e in order to be fixed to the hook mounting portion 12 by multiple screws 14. In this example, the supported portion 21b has two fastening portions 21e. It should be noted that the support shape, the number and position of the fastening parts, and the support mechanism (fastening) can be appropriately modified as long as they can be locked to the object being locked.

[0116] Alternatively, the locking part may not be a hook mounting part, or a hook may not be used. Instead, the main body 10 or the cover 15 may be provided with a shape that can lock with the object being locked.

[0117] Furthermore, tools are not limited to rebar tying machines. For example, tools such as electric drill bit drives are not considered consumable components; the tool's center of gravity is determined by the power supply source, such as a battery. Additionally, in tools that use compressed air as a power source to drive nails and other fasteners, the compressed air is supplied from an external air compressor; therefore, they are not considered consumable components; rather, the tool's center of gravity is determined by the fastener itself.
