[0009] Hereinafter, embodiments of the tool holder according to the present invention will be described in detail with reference to the accompanying drawings. Note that the embodiments described below are merely examples of the present invention including their dimensions and the like, and the present invention is not limited to the following embodiments and can be appropriately changed within the scope of the technical idea of the present invention.

[0010] The tool holder 1 according to an embodiment of the present invention is, for example, attached to a worker's belt 4 or the like as shown in FIG. 1, and latches a latching fitting 2 attached to a tool 3 such as an impact driver as shown in FIG. 2(a), as shown in FIG. 2(b). In the following description, before explaining the configuration of the tool holder 1 according to the embodiment of the present invention, the configuration of the latching fitting 2 attached to the tool 3 will be described first. Also, in this embodiment, an impact driver will be described as an example of the tool 3.

[0011] **Configuration of the Latching Fitting 2** The latching fitting 2 is attached to the back side (worker side) of the tool 3 as shown in FIG. 2(a) etc., and is a fitting that latches onto the tool holder 1 according to the embodiment of the present invention attached to a worker's belt 4 or the like as shown in FIGS. 1 and 2(b), and is configured in substantially the same shape as that of Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2022-7226) etc.

[0012] In other words, as shown in Figures 2(a) and 3(a) and 3(b), the latching fitting 2 is a clip-shaped fitting with both sides and the bottom open, and it bends from the top of the intermediate part 2a, forming an almost inverted U shape when viewed from the side with the tool fixing piece 2b and the holder latching piece 2c.

[0013] The connecting section 2a is bent into an R shape to prevent the tool 3 and tool holder 1 from swinging when locked together. However, when attaching the tool 3, tool pouch, tool belt, etc., the connecting section 2a may be bent into a right-angle or other angled shape instead of an R shape.

[0014] The tool fixing piece 2b has a horizontally elongated slot 2b1 for inserting screws or the like to fix it to the tool 3, and the holder hooking piece 2c has a vertically elongated hooking opening 2c1 in the center, such as a vertical oval or rectangle.

[0015] Here, as shown in Figure 3(c), the width of the latching opening 2c1 is H1, and the height is H2 (>H1).

[0016] In this embodiment, the example shows the fastening fitting 2 being attached to the tool 3 via the elongated hole 2b1. However, in the present invention, the tool fixing piece 2b may be omitted, and a fitting with a fastening opening 2c1 having a folded-over bend at the upper end may be directly fixed to another tool, tool holder, etc. Furthermore, the fastening fitting 2 attached to the tool 3 may be a commercially available one, or one that is already attached to the tool 3 such as an impact driver, or it may be purchased separately, or it may be attached to the tool 3 from one that is included as an accessory to the tool holder 1 in the embodiment of the present invention.

[0017] <Configuration of the tool holder 1 according to an embodiment of the present invention> As described above, the tool holder 1 of the embodiment according to the present invention is used by being attached to a worker's belt 4, etc., as shown in Figure 1, and consists of a base portion 11 that is attached to a worker's belt 4, etc., and a latching projection 12, a first guard piece 13, a second guard piece 14, and a magnetic portion 15, etc., provided on the base portion 11.

[0018] (Base section 11) The base portion 11 is formed by cutting and bending a single sheet of metal steel into a predetermined shape, and is equipped with a tool-holding side 11a and a worker side 11b. A pair of belt-passing sections 11c, 11c are provided so that the worker's belt 4 passes from the tool-holding side 11a to the worker side 11b and then back out to the tool-holding side 11a. In order to facilitate the passing of the belt 4 through the belt-passing sections 11c, 11c, the base portion 11 is provided with a pair of lateral inclined pieces 11d, 11d that are bent diagonally at each of the belt-passing sections 11c, 11c so as to be convex toward the tool-holding side 11a, and an upward inclined piece 11e is also provided on the upper part of the base portion 11.

[0019] Furthermore, in order to reduce weight, the base portion 11 is also provided with a pair of first material-cutting holes 11f, 11f, a second material-cutting hole 11g, a pair of third material-cutting holes 11h, 11h, a fourth material-cutting hole 11i, etc., of arbitrary shapes as appropriate.

[0020] (Latching protrusion 12) The latching projection 12 is formed by cutting a narrower section at the bottom and a wider section at the top in the center of the base portion 11, then cutting it diagonally towards the tool latching side 11a to create a narrow section 12a and a wide section 12b. It is the part that is inserted into the latching opening 2c1 formed in the holder latching piece 2c of the latching fitting 2 to latch the latching fitting 2.

[0021] Here, as shown in Fig. 5(a), the narrow-width portion 12a of the latching projection 12 is inserted into the latching opening 2c1 of the holder latching piece 2c as will be described later. Therefore, the lateral width h1 of the narrow-width portion 12a is set to be less than or equal to the lateral width H1 of the latching opening 2c1 of the holder latching piece 2c of the latching fitting 2 (see Fig. 3(b)), that is, the relationship is h1≦H1.

[0022] Also, as will be described later, after the wide-width portion 12b of the latching projection 12 is passed through the latching opening 2c1 of the horizontally oriented holder latching piece 2c, when it becomes vertically oriented, in order to prevent the latching fitting 2 from easily falling off the tool holder 1, the lateral width h2 of the wide-width portion 12b is greater than the lateral width H1 of the latching opening 2c1 of the holder latching piece 2c of the latching fitting 2 (see Fig. 3(b)) and less than or equal to the vertical width H2 of the latching opening 2c1, that is, the relationship is H1 < h2≦H2. Also, when h1 is included, the relationship is h1≦H1 < h2≦H2.

[0023] (First guard piece 13) As shown in Fig. 5(a), (b), etc., the first guard piece 13 rises from the tool latching side surface 11a of the base portion 11 below the latching projection 12 and on the left side of the center line CL lowered from the center of the latching projection 12, on the belt passing portion 11c side of the tool latching side surface 11a, and has a first guard piece standing portion 13a that guards against the holder latching piece 2c of the latching fitting 2 facing the holder latching piece 2c of the latching fitting 2 on the left side of the center line CL, and a first guard piece latching portion 13b that is bent approximately 90 degrees from the upper end portion of the first guard piece standing portion 13a, extends to the right side in the drawing, which is the opposite side across the center line CL while facing the tool latching side surface 11a of the base portion 11, and has an open end at the tip.

[0024] The first guard piece upright portion 13a is constructed to extend from the tool hooking side 11a of the base portion 11 by at least twice the thickness of the holder hooking piece 2c of the hooking fitting 2 plus the thickness of the tip of the second guard piece 14, so that when the hooking opening 2c1 of the hooking fitting 2 is hooked onto the hooking projection 12, the first guard piece upright portion 13a passes between the first guard piece upright portion 13a and the tool hooking side 11a of the base portion 11, and furthermore, the hooking fitting 2 can be temporarily attached to the first guard piece upright portion 13a itself.

[0025] The first guard piece latch portion 13b is bent at approximately 90 degrees from the upper end of the first guard piece upright portion 13a, and extends parallel to the tool latch side 11a of the base portion 11, across the center line CL, to the opposite side, the belt loop portion 11c on the right side in the diagram. Its tip is provided with an inclined piece 13c that extends at a further 30-degree angle to facilitate the latching of the holder latch piece 2c of the latch fitting 2.

[0026] (Second guard piece 14) The second guard piece 14 is cut and bent in a rectangular shape from the inclined piece 13c side of the first guard piece 13, which is on the right side of the base piece 11 in the diagram, below the hooking projection 12 on the tool hooking side surface 11a of the base piece 11 and on the opposite side from the rising part of the first guard piece 13 from the center line CL drawn from the center of the hooking projection 12, and extends diagonally toward the opposite side to just before the wide part 12b on the upper part of the hooking projection 12, as shown in Figures 5(a), (b) and 7(b), and its tip is configured to be an open end.

[0027] Furthermore, the second guard piece 14 is configured to extend diagonally from the tool-hooking side surface 11a of the base portion 11 until the height of its tip from the tool-hooking side surface 11a of the base portion 11 is at least equal to or greater than the combined thickness of the holder-hooking piece 2c of the hooking fitting 2 and the magnet portion 15. In this embodiment, the tip of the second guard piece 14 extends to a height equal to or slightly greater than the combined thickness of the holder-hooking piece 2c of the hooking fitting 2 and the magnet portion 15. When the rightmost end of the holder-hooking piece 2c of the hooking fitting 2 is sandwiched between the second guard piece 14 and the tool-hooking side surface 11a, the holder-hooking piece 2c of the hooking fitting 2 is attracted to the magnet portion 15 below the hooking projection 12.

[0028] Furthermore, as shown in Figures 5(a) and 7(b), the second guard piece 14 extends diagonally in a straight line, so that when the holder hook piece 2c of the hooking fitting 2 shakes or moves between the second guard piece 14 and the tool hooking side surface 11a, the hooking fitting 2 can be securely hooked by the wedge effect between the base portion 11 and the tool hooking side surface 11a.

[0029] (Magnet section 15) The magnetic part 15 is located on the tool-hooking side surface 11a of the base part 11, below the hooking projection 12, so as to face the first guard piece 13, and magnetically attracts the holder hooking piece 2c of the hooking fitting 2 from its back side, thereby fixing the holder hooking piece 2c of the hooking fitting 2.

[0030] <Method of use of the tool holder 1 according to the embodiment of the present invention> Next, the method of using the tool holder 1 of the embodiment of the present invention, configured as described above, will be explained with reference to the drawings. In Figures 8 to 16, only the tool holder 1 and the latching fitting 2 of the embodiment of the present invention are shown, and the latching and detaching operations of the latching fitting 2 will be explained.

[0031] (1) Preparation (Attach tool holder 1 to the worker's waist, and attach fastening bracket 2 to tool 3.) When attaching the tool holder 1 to the worker's waist, first, as shown in Fig. 1 etc., the worker sequentially passes the belt 4 through the pair of belt passages 11c, 11c of the base portion 11 of the tool holder 1, and winds the belt 4 around the worker's waist from above the clothing to attach the tool holder 1 to the worker's waist.

[0032] On the other hand, for a tool 3 such as an impact driver, as shown in Fig. 2(a), attach and fix a latching fitting 2 with screws or bolts 5 etc., and latch the latching fitting 2 fixed to the tool 3 to the tool holder 1 installed around the worker's waist, and attach the tool holder 1 to the worker's waist as shown in Fig. 2(b).

[0033] (2) Procedure for latching (main latching) the latching fitting 2 fixed to the tool 3 to the tool holder 1 in a stable state When the worker passes the belt 4 wound around the waist through the pair of belt passages 11c, 11c of the tool holder 1 and attaches the tool holder 1 to the worker's waist, subsequently, the worker grasps the tool 3 to which the latching fitting 2 is attached and performs work. When not using the tool 3, attach the latching fitting 2 fixed to the tool 3 to the tool holder 1 fixed with the belt 4 around the worker's waist.

[0034] (2-1) When latching to the tool holder 1 of the present embodiment in a stable state At that time, when not using the tool 3 that has been used so far for a while and latching it to the tool holder 1 of the present embodiment in a stable state, as shown in Fig. 8, turn the latching fitting 2 sideways and lower it toward the latching projection 12 of the tool holder 1.

[0035] At that time, since the relationship of H1 < h2 ≦ H2 is as described above, the latching opening 2c1 of the holder latching piece 2c cannot pass through the wide portion 12b of the latching projection 12 in the vertical direction (up and down direction). However, as shown in Fig. 8, when the latching opening 2c1 of the holder latching piece 2c is turned sideways, as shown in Fig. 9, the latching opening 2c1 of the holder latching piece 2c can pass through the wide portion 12b of the latching projection 12.

[0036] As shown in Figure 9, once the hooking projection 12 of the tool holder 1 can be passed through the hooking opening 2c1 of the holder hooking piece 2c of the hooking fitting 2, the hooking fitting 2 is rotated clockwise as shown in Figure 10.

[0037] Then, the holder latch piece 2c is inserted between the second guard piece 14 and the first guard piece upright portion 13a of the first guard piece 13, and when it is rotated clockwise by 90 degrees, as shown in Figures 11(a) and (b), the lower surface of the connecting portion 2a of the latch fitting 2 approaches or comes into contact with the wide portion 12a of the upper part of the latching projection 12 of the tool holder 1, and the tool 3 is latched to the tool holder 1, and the lower part of the holder latch piece 2c of the latch fitting 2 is attracted to the magnetic portion 15.

[0038] Therefore, after passing the wide portion 12b of the latching projection 12 through the latching opening 2c1 of the holder latching piece 2c, if the latching fitting 2 is rotated to a vertical position, the width h2 of the wide portion 12b of the latching projection 12 is larger than the width H2 of the latching opening 2c1 of the holder latching piece 2c. As a result, the latching fitting 2 fixed to the tool 3 can be latched to the latching projection 12 of the tool holder 1 in a way that makes it impossible to remove when the tool is in a vertical position. This prevents the tool from easily falling off even without using a plate spring, improving work efficiency.

[0039] Furthermore, when the latching fitting 2 is rotated 90 degrees and its lower part is attracted to the magnetic part 15, the upper right side of the lower part of the holder latching piece 2c is guarded in opposition to the second guard piece 14, while the upper left side of the lower part of the holder latching piece 2c of the latching fitting 2 is guarded in opposition to the first guard piece upright portion 13a of the first guard piece 13. Thus, both the left and right sides are guarded by the second guard piece 14 and the first guard piece upright portion 13a of the first guard piece 13.

[0040] Therefore, even if a worker moves or works with the tool 3 attached to the tool holder 1, which is secured around the worker's waist with a belt 4, the wide portion 12b of the tool holder 1's latching projection 12 and the magnetic portion 15 below it prevent vertical displacement, and the second guard piece 14 and the first guard piece upright portion 13a of the first guard piece 13 guard against lateral (left-right) displacement of the latching fitting 2, thus reliably preventing the tool 3 from falling out of the tool holder 1.

[0041] In addition, the state shown in Figures 11(a) and (b) is when the holder latching piece 2c of the latching fitting 2 is attracted to the magnetic part 15 provided on the tool latching side surface 11a of the base part 11 of the tool holder 1, and the lower surface of the connecting part 2a of the latching fitting 2 is floating above the wide part 12a of the upper part of the latching projection 12 of the tool holder 1.

[0042] In particular, in this embodiment, the tip of the second guard piece 14 extends to a height equal to or slightly greater than the sum of the thickness of the holder latch piece 2c of the latch fitting 2 and the thickness of the magnet part 15. Therefore, when the right end of the holder latch piece 2c of the latch fitting 2 is sandwiched between the second guard piece 14 and the tool latch side surface 11a, the holder latch piece 2c of the latch fitting 2 is attracted to the magnet part 15 below the latch projection 12. In this respect as well, the tool 3 can be reliably prevented from falling out of the tool holder 1.

[0043] Furthermore, as shown in Figures 5(a) and 7(b), the second guard piece 14 extends diagonally in a straight line, and the wedge effect between it and the tool-hooking side surface 11a of the base portion 11 securely hooks the hooking fitting 2, thereby more reliably preventing the tool 3 from falling out of the tool holder 1.

[0044] (2-2) When removing a tool 3 that is securely attached to the tool holder 1 of this embodiment As shown in (2-1), when removing the tool 3 after securely attaching it to the tool holder 1 of the embodiment, the holder attachment piece 2c of the attachment fitting 2 is attracted by the magnetic part 15 below the attachment projection 12 of the tool holder 1, and the lateral (left-right) displacement of the attachment fitting 2 is also guarded by the second guard piece 14 and the first guard piece upright part 13a of the first guard piece 13. Therefore, as shown in Figures 12(a) and (b), the worker pulls the holder attachment piece 2c of the attachment fitting 2 in the direction of the arrow so that it moves away from the worker's body, detaching the holder attachment piece 2c of the attachment fitting 2 from the magnetic part 15 below the attachment projection 12 of the tool holder 1, and also from the second guard piece 14.

[0045] Next, in order to move the holder latch piece 2c of the latching fitting 2 to the outside of the first guard piece 13 of the tool holder 1, rotate the holder latch piece 2c of the latching fitting 2 counterclockwise as shown in Figure 13, and when the latching fitting 2 is in an almost horizontal position as shown in Figure 14, move the holder latch piece 2c of the latching fitting 2 above the first guard piece 13 of the tool holder 1 and to the outside of the first guard piece 13 of the tool holder 1, and by lifting the latching fitting 2 upward as shown in Figure 15, the latching opening 2c1 of the holder latch piece 2c of the latching fitting 2 is removed from the latching projection 12 of the tool holder 1.

[0046] With the above steps, the tool 3, which is securely attached to the tool holder 1 of this embodiment, can be removed.

[0047] (3) Procedure for temporarily attaching the fastening bracket 2 fixed to the tool 3 to the tool holder 1 When the tool 3 is secured using the procedure described in (2) above, which involves "securing the fastening bracket 2 fixed to the tool 3 to the tool holder 1 in a stable state (permanent fastening)," the fastening bracket 2 fixed to the tool 3 is prevented from shifting vertically by the fastening projection 12 of the tool holder 1 and the magnetic part 15 below it, and is also protected from shifting horizontally (left and right) by the second guard piece 14 and the first guard piece upright part 13a of the first guard piece 13. This is good because the tool 3 is secured in a stable state when it is not used for a long time. However, when the tool 3 is used frequently in the same place, it is necessary to insert and remove the fastening projection 12 of the tool holder 1 into the fastening opening 2c1 of the holder fastening piece 2c of the fastening bracket 2, or to fasten the fastening bracket 2 fixed to the tool 3 to the tool holder 1, or to rotate the fastening bracket 2 fixed to the tool 3 each time it is removed, which is time-consuming and troublesome.

[0048] Therefore, if the tool 3 is used frequently in the same location, instead of permanently securing it using the procedure described in (2) for "securing the fastening bracket 2 fixed to the tool 3 to the tool holder 1 in a stable state (permanent fastening)", temporarily fasten the fastening bracket 2 fixed to the tool 3 to the tool holder 1.

[0049] Temporarily attaching the tool to the tool holder 1 involves not inserting the hooking projection 12 of the tool holder 1 into the hooking opening 2c1 of the hooking fitting 2 fixed to the tool 3, but rather, as shown in Figures 16(a) and (b), simply hooking the holder hooking piece 2c of the hooking fitting 2 onto the first guard piece hooking portion 13b of the first guard piece 13 of the tool holder 1.

[0050] Since the tool holder 1's latching projection 12 is not inserted into the latching opening 2c1 of the latching fitting 2 fixed to the tool 3, the latching fitting 2 fixed to the tool 3 can be lowered in an up-and-down direction without rotating it, saving time and effort. However, because the holder latching piece 2c of the latching fitting 2 is temporarily hooked onto the first guard piece 13 of the tool holder 1, downward detachment is reliably prevented. Furthermore, the magnetic part 15 prevents vertical displacement, and the second guard piece 14 and the first guard piece upright portion 13a of the first guard piece 13 prevent lateral (left-right) displacement of the latching fitting 2, thus reliably preventing the tool 3 from falling out of the tool holder 1.

[0051] (4) Procedure for temporarily attaching the hook 2' of another tool 5, such as a measuring tape, to the tool holder 1, instead of the hook 2 attached to tool 3. Furthermore, other tools 2 such as measuring tapes are equipped with metal fastening fittings 2' that have holder fastening pieces 2c' for fastening to a worker's belt 4, etc. As shown in Figures 17(a) and (b), by temporarily fastening the holder fastening piece 2c' of the fastening fitting 2' to the first guard piece 13 of the tool holder 1, similar to the holder fastening piece 2c of the fastening fitting 2, other tools 5 such as measuring tapes can be reliably prevented from falling downwards. At the same time, the magnetic part 15 prevents vertical displacement, and the second guard piece 14 and the first guard piece upright part 13a of the first guard piece 13 prevent horizontal (left-right) displacement of the fastening fitting 2'. Thus, other tools 5 such as measuring tapes can be fastened in a way that minimizes the risk of them falling out of the tool holder 1.

[0052] <Summary of the tool holder 1 according to the embodiment of the present invention> As described above, the tool holder 1 of the embodiment according to the present invention has a base portion 11 that is attached to the worker's belt 4, and a hooking projection 12 that protrudes upward from the tool hooking side surface 11a of the base portion 11 for hooking the tool 3. The hooking projection 12 has a narrow portion 12a that is erected from the tool hooking side surface 11a of the base portion 11, and a wide portion 12b provided at the tip of the narrow portion 12a. The width h1 of the narrow portion 12a (see Figure 5(a)) is less than or equal to the width H1 of the hooking opening 2c1 of the holder hooking piece 2c (see Figure 3(b)), while the width h2 of the wide portion 12b (see Figure 5(a)) is greater than the width H2 of the hooking opening 2c1 of the holder hooking piece 2c (see Figure 3(b)), and less than or equal to the vertical width H2 of the hooking opening 2c1.

[0053] Therefore, by orienting the fastening fitting 2 horizontally and passing the wide portion 12b of the fastening projection 12 through the fastening opening 2c1 of the holder fastening piece 2c, and then orienting the fastening fitting 2 vertically, the wide portion 12b of the fastening projection 12 is fastened to the fastening opening 2c1 of the holder fastening piece 2c. This allows the fastening fitting 2 fixed to the tool 3 to be easily fastened to the fastening projection 12 of the tool holder 1. Thus, even without using a plate spring, the tool can be fastened to prevent it from easily falling off, and by operating in the reverse direction, it can be easily removed, improving work efficiency.

[0054] Furthermore, the tool holder 1 of the embodiment according to the present invention further includes a first guard piece 13 that rises from the left side in the figure, which is below the hooking projection 12 on the tool hooking side surface 11a of the base portion 11 and on one side of the center line CL drawn from the center of the hooking projection 12, and extends toward the right side in the figure, which is the opposite side, with its tip being an open end, and facing at least one side of the holder hooking piece 2c that passes through the hooking projection 12; and a second guard piece 14 that rises from the other side in the figure, which is below the hooking projection 12 on the tool hooking side surface 11a of the base portion 11 and on the opposite side of the first guard piece 13 with respect to the center line CL, and extends toward one side, with its tip being an open end, and facing at least the other side of the holder hooking piece 2c that passes through the hooking projection 12.

[0055] Therefore, when the latching opening 2c1 of the latching fitting 2 attached to the tool 3 is latched onto the latching projection 12 of the tool holder, the holder latching piece 2c of the latching fitting 2 is guarded on both sides by the first guard piece upright portion 13a and the second guard piece 14 of the first guard piece 13, thereby suppressing the range of movement of the latching fitting 2 latched onto the latching projection 12 of the tool holder. This prevents the tool 3 from easily falling off even without using a plate spring.

[0056] Furthermore, in the tool holder 1 of the embodiment of the present invention, the first guard piece 13 includes a first guard piece upright portion 13a that stands upright on the tool hooking side surface 11a of the base portion 11 to a height of at least twice the thickness of the holder hooking piece 2c, and a first guard piece hooking portion 13b that extends from the upper end of the first guard piece upright portion 13a toward the other side to at least the width of the holder hooking piece 2c, with its tip being an open end. The second guard piece 14 extends diagonally toward one side from the tool hooking side surface 11a of the base portion 11, with its tip being an open end, and has a height greater than or equal to the sum of the thickness of the holder hooking piece 2c and the thickness of the magnet portion 15 relative to the tool hooking side surface 11a of the base portion 11, and the distance between the first guard piece upright portion 13a of the first guard piece 13 and the tip of the second guard piece 14 is at least the width of the holder hooking piece 2c.

[0057] Therefore, after hooking the hooking opening 2c1 of the hooking fitting 2 attached to the tool 3 onto the hooking projection 12 of the tool holder, the holder hooking piece 2c of the hooking fitting 2 can be guarded on both sides by the first guard piece upright portion 13a and the second guard piece 14 of the first guard piece 13 by rotating it in the in-plane direction on the tool hooking side surface 11a of the base portion 11. As a result, the tool can be secured so that it does not easily fall off even without using a plate spring, and can be easily removed by operating in the reverse direction, thereby improving work efficiency.

[0058] Furthermore, by hooking the holder hook piece 2c of the hooking fitting 2 onto the first guard piece hooking portion 13b of the first guard piece 13, tools can be temporarily hung, thereby improving the efficiency of work using tools. Additionally, the hooking fitting 2' provided on the measuring tape 5, etc., can also be temporarily hung on the first guard piece hooking portion 13b of the first guard piece 13, thereby improving the efficiency of work using the measuring tape 5, etc., and improving ease of use.

[0059] In particular, since the second guard piece 14 extends diagonally from the tool-hooking side surface 11a of the base portion 11, the wedge effect between the second guard piece 14 and the tool-hooking side surface 11a of the base portion 11 when the lower part of the holder-hooking piece 2c of the hooking fitting 2 is passed through allows the hooking fitting 2 to be hooked more securely.

[0060] Furthermore, in the tool holder 1 of the embodiment according to the present invention, the second guard piece 14 is provided between the first guard piece latching portion 13b of the first guard piece 13 and the tool latching side surface 11a of the base portion 11, and there is a gap of at least the thickness of the holder latching piece 2c between the first guard piece latching portion 13b of the first guard piece 13 and the tip of the second guard piece 14.

[0061] Therefore, the vertical length of the base section 11 can be shortened, which in turn reduces the weight of the base section 11, improving work efficiency.

[0062] Furthermore, in the tool holder 1 of the embodiment according to the present invention, the fastening device is a metal fastening fitting 12, and below the fastening projection 12 on the tool fastening side surface 11a of the base portion 11, there is a magnetic portion 15 that attracts the holder fastening piece 2c of the fastening device by magnetic force.

[0063] Therefore, when the latching opening 2c1 of the latching fitting 2 attached to the tool 2 is latched onto the latching projection 12 of the tool holder, the holder latching piece 2c of the latching fitting 2 is inserted between the second guard piece 14 and the tool latching side surface 11a of the base portion 11. This not only guards both the left and right sides of the lower part of the holder latching piece 2c of the latching fitting 2 between the first guard piece 13 and the tool latching side surface 11a of the base portion 11, but also attracts the holder latching piece 2c of the latching fitting 2 with magnetic force, thus enabling the latching fitting 2 to be latched more securely.

[0064] In the description of the tool holder 1 in the above embodiment, the base portion 11 was described as being provided with a first guard piece 13, a second guard piece 14, and a magnet portion 15. However, the present invention is not limited to this, and the magnet portion 15 may be omitted, and the holder hook piece 2c of the hooking fitting 2 may be hooked with the hooking projection 12, the first guard piece 13, and the second guard piece 14. Alternatively, the first guard piece 13 and the second guard piece 14 may be omitted, and the holder hook piece 2c of the hooking fitting 2 may be hooked with the hooking projection 12 and the magnet portion 15. Furthermore, the first guard piece 13, the second guard piece 14, and the magnet portion 15 may be omitted, and the holder hook piece 2c of the hooking fitting 2 may be hooked with only the hooking projection 12. Of course, the second guard piece 14 may be omitted, and the holder may be composed of the hooking projection 12, the first guard piece 13, and the magnet portion 15.

[0065] Furthermore, in the description of the tool holder 1 of the above embodiment, the first guard piece 13 and the second guard piece 14 were described as being provided in an overlapping manner with a gap between them. However, the present invention is not limited to this, and the first guard piece 13 and the second guard piece 14 may be provided offset vertically without overlapping, or the second guard piece 14 may be constructed in the same way as the first guard piece 13 with a second guard piece upright portion and a second guard piece latching portion, or the first guard piece 13 may be constructed by extending it diagonally in a straight line like the second guard piece 14.
