Description

Technical Field

[0001] The present invention relates to a suspension tool for power tools.

Background Art

[0002] Conventionally, many power tools such as impact drivers, driver drills, and hammer drills have had genuine hooks attached as suspension tools for hooking onto an operator's waist belt. This hook was designed to be attached to the lower part of the main body near the battery (see, for example, Patent Documents 1 to 3 below). Since these hooks are structured to be simply inserted from above into the belt, if the operator squats or the power tool comes into contact with an obstacle such as a scaffold or ladder while suspended and is lifted upward, the tool may come off the belt and fall.

[0003] To prevent falling, a connection part has been proposed for the hook so that it can be connected to a suspended member such as a carabiner (see, for example, Patent Document 4 below). There is also a suspension tool called an impact hook that is configured to be replaceable and attachable in place of the genuine hook of a power tool. It is known to have a connection part that can be connected to a suspended member such as a carabiner and is configured to be fixable to the power tool. The suspension tool that is attached in place of the genuine hook is configured to be fixable using a fixed part such as a screw hole or groove provided in advance for attaching the genuine hook.

[0004] Such a suspension tool can suspend a power tool by attaching a suspended member such as a carabiner to the waist belt and connecting the connection part to this suspended member. Even if the operator squats or the power tool comes into contact with surrounding obstacles while in the suspended state, the suspension tool will not come off the suspended member, preventing the power tool from falling.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the positions and orientations of the fixed parts such as screw holes and grooves provided in advance in power tools differ from manufacturer to manufacturer and from power tool to power tool, and the center of gravity positions of power tools also differ from power tool to power tool. In addition, the appropriate hanging method, the appropriate hanging orientation and swinging state that do not interfere during walking or work also differ from worker to worker or from work to work. Therefore, in the conventional hanging tools that are attached instead of the genuine hooks, there has been a problem that when they are attached to various power tools, it frequently happens that the power tools cannot be hung at appropriate positions.

[0007] Therefore, in the present invention, in order to solve such problems, in a hanging tool that can be attached instead of the genuine hanging tool for a power tool, it is an object to provide a hanging tool for a power tool that can hang the power tool at an appropriate position even when attached to various power tools.

Means for Solving the Problems

[0008] In order to solve the above problems, the hoist for a power tool according to the present invention is a hoist for a power tool for connecting and hoisting a rechargeable power tool to a suspended part, and includes a base piece that can be mounted at a predetermined position of the power tool, a connecting piece that can be connected to the suspended part, a connecting part that rotatably connects the base piece and the connecting piece, a holding part that can hold the rotational positions of the base piece and the connecting piece, and a fixing part that can fix at least one of the base piece and the connecting piece to the power tool.

[0009] According to the present invention, a base piece that can be mounted on a power tool and a connecting piece that can be connected to a suspended part are rotatably connected by a connecting part, and the rotational positions of the base piece and the connecting piece can be held by a holding part, and the base piece or the connecting piece can be fixed to the power tool by a fixing part. Therefore, according to the center of gravity position of the power tool, the mounting position of the hoist provided on the power tool, and further according to the operator and the work content, by displacing the connecting piece in the rotational direction with respect to the base piece and holding and fixing it, the connecting piece for connecting to the suspended part can be arranged at an appropriate position with respect to the power tool. As a result, it is possible to provide a hoist for a power tool that can be mounted in place of the genuine hoist for various power tools and can hoist the power tool at an appropriate position even when mounted on various power tools.

[0010] The hoist for a power tool according to the present invention may include a fixing part that can fix both the base piece and the connecting piece to the power tool. In this way, even if they are rotatably connected to each other, it is possible to prevent excessive load from being applied to the connecting part and being damaged during use, and it is easy to ensure sufficient strength of the hoist. Further, in the hoist for a power tool according to the present invention, the holding part may include a plurality of positioning parts provided circumferentially at a certain distance from the connecting part on one of the base piece and the connecting piece, and a positioning receiving part provided at the certain distance from the connecting part on the other and capable of holding some of the positioning parts. In this way, it is easy to displace and hold the base piece and the connecting piece in the rotational direction. In that case, by fixing the positioning portion and the positioning receiving portion to the fixed portion provided on the power tool, a fixing portion capable of fixing both the base piece and the connecting piece to the power tool may be provided. In this way, it is possible to simply provide a structure that can prevent the connection portion from being damaged by being loaded with an excessive load during use.

[0011] Further, the connection portion has a fulcrum portion provided at the center of the plurality of positioning portions on one side, and a fulcrum receiving portion provided on the other side and capable of connecting the fulcrum portion to a plurality of positions. A plurality of the positioning receiving portions may be provided on the other side at a constant distance from the plurality of positions of the fulcrum receiving portion. In this way, by selecting and arranging one position from a plurality of fulcrum receiving portions for the fulcrum portion, the position of the connection portion between the base piece and the connecting piece can be changed, and the degree of freedom in attaching the suspension tool to the power tool can be improved.

[0012] In that case, the fulcrum receiving portion may be formed of a long hole in which the fulcrum portion can slide and move. In this way, the fulcrum portion can be easily moved between a plurality of fulcrum receiving portions, and the position of the connection portion between the base piece and the connecting piece can be easily changed. Also, while the suspension tool is fixed to the power tool and in use, since the positioning portion is held by the positioning receiving portion, the fulcrum portion does not move within the long hole, and it is possible to prevent the position of the connection portion between the base piece and the connecting piece from changing during use and to use it stably.

[0013] Further, in the suspension tool for the power tool of the present invention, the connecting piece may integrally have an annular connecting portion capable of passing through and connecting a first suspended portion, and an insertion connecting portion provided to protrude in a direction different from the annular connecting portion and capable of being inserted into and connected to a second suspended portion. By doing so, by passing through and connecting the first suspended part to the annular connecting part, the power tool can be surely prevented from falling and suspended. On the other hand, by inserting and connecting the insertion connecting part to the second suspended part, the power tool can be simply and easily suspended. Therefore, according to various usage conditions, the operator can properly select the suspension method, improving the usability.

[0014] In order to solve the above problems, another suspension tool for a power tool of the present invention is a suspension tool for a rechargeable power tool including a grip part and a main body part having an output end part, which can be suspended from a plurality of types of suspended parts. It is characterized in that it includes a connecting piece integrally having a base part that can be attached to a position away from the main body part of the grip part, an annular connecting part that protrudes from the base part and can be connected by passing through the first suspended part, and an insertion connecting part that protrudes from the base part in a direction different from the annular connecting part and can be inserted and connected to the second suspended part. And a fixing part for fixing the connecting piece to the power tool so that the circumferential direction around the base part is held at a position where the insertion piece protrudes toward the main body part side and the annular connecting part protrudes from the grip part.

[0015] According to the present invention, since the annular connecting part and the insertion connecting part are provided on the connecting piece, by passing through and connecting the first suspended part to the annular connecting part, the power tool can be surely prevented from falling and suspended. On the other hand, by inserting and connecting the insertion connecting part to the second suspended part, the power tool can be simply and easily suspended. Therefore, according to various usage conditions, the operator can properly select the suspension method, improving the usability. Moreover, since the connecting piece can be connected to the side surface of the grip part and fixed by the fixing part at the circumferential position around the base part so that the annular connecting part and the insertion connecting part protrude in a predetermined direction, the annular connecting part and the insertion connecting part can be arranged to protrude in directions suitable for their respective functions around the base part, and the usability can be further improved according to various usage conditions.

Effect of the Invention

[0016] According to the present invention, there is provided a suspension tool that can be attached in place of an original suspension tool for a power tool, and can suspend the power tool at an appropriate position even when attached to various power tools.

Mode for Carrying Out the Invention

[0018] [First Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a state where the suspension tool of this embodiment is attached to and suspended from the battery portion of the power tool, and FIGS. 2 to 5 are a front view, a rear view, a plan view, and a side view of the suspension tool, respectively.

[0019] The suspension tool 20 of this embodiment is a member for connecting and suspending a rechargeable power tool 10 to a suspended portion 11 such as a carabiner, and is attached in place of the genuine hook of the power tool 10. This suspension tool 20 has a base piece 21 that can be attached to a predetermined position of the power tool 10 and a connecting piece 22 that can be connected to the suspended portion 11. Further, the suspension tool 20 includes a connecting portion 24 that connects the base piece 21 and the connecting piece 22 so as to be displaceable in the rotational direction, a holding portion 25 that can hold the positions in the rotational direction, and a fixing portion 26 that can fix at least one of the base piece 21 and the connecting piece 22 to the power tool 10. In this embodiment, both the base piece 21 and the connecting piece 22 are configured to be fixable to the power tool 10.

[0020] As shown in FIGS. 6(a) and 6(b), the base piece 21 has a folding portion 28 that can be locked in a groove 12 provided in advance in the power tool 10, and a support portion 29 that is bent in a shape that bends with the folding portion 28, and is bent in an L-shaped cross section. This base piece 21 is made of a formed product obtained by press-forming a metal plate material and performing heat treatment. The support portion 29 of the base piece 21 is provided with a long hole-shaped fulcrum receiving portion 31 for constituting the connecting portion 24 and two positioning receiving portions 32 each formed of a through hole for constituting the holding portion 25. In this embodiment, the long-hole-shaped fulcrum receiving portion 31 and the two positioning receiving portions 32 are arranged at line-symmetrical positions with respect to the axis L orthogonal to the folding portion 28.

[0021] The fulcrum receiving portion 31 is a portion that rotatably connects the connecting piece 22, and is a portion where the fulcrum portion 38 of the connecting piece 22 described later is arranged in a state of being connected by the connecting member 33. As an example, the connecting member 33 employs members such as rivets, bolts and nuts, and the base piece 21 and the connecting piece 22 may be connected inseparably or separably by these connecting members 33. The long-hole shape of the fulcrum receiving portion 31 is configured such that the fulcrum portion 38 of the connected connecting piece 22 can move along the long hole. The axis of this long-hole shape is formed in a curved shape, and in this embodiment, it is bent in a substantially V shape. The two positioning receiving portions 32 are provided corresponding to each end of the fulcrum receiving portion 31. In this embodiment, the distance between one end of the fulcrum receiving portion 31 and one positioning receiving portion 32, and the distance between the other end of the fulcrum receiving portion 31 and the other positioning receiving portion 32 are both set to a predetermined constant distance.

[0022] As shown in FIGS. 7(a) and 7(b), the connecting piece 22 is composed of a plate-like body, and a base portion 35 is provided on one end side so as to be arranged opposite along the surface of the base piece 21, and a connecting portion 36 for connecting to the suspended portion 11 is provided on the other end side.

[0023] The base portion 35 is provided with a fulcrum portion 38 for constituting the connecting portion 24 and a positioning portion 39 for constituting the holding portion 25. The positioning portion 39 is formed by arranging a large number of positioning holes 39a formed of through holes at substantially equal intervals in the circumferential direction around the fulcrum portion 38. The distance between the fulcrum portion 38 and each positioning portion 39 is the same constant distance as that between the fulcrum receiving portion 31 of the base piece 21 and the end of the positioning receiving portion 32. The connecting portion 36 is formed by a through opening provided in a substantially triangular annular shape so as to expand as it separates from the base portion 35.

[0024] The connecting portion 24 that rotatably connects these base pieces 21 and connecting pieces 22 is configured such that the fulcrum portion 38 of the connecting piece 22 and the fulcrum receiving portion 31 of the base piece 21 are rotatably and inseparably connected by a connecting member 33 as shown in FIGS. 1 and 3. In this embodiment, the connecting member 33 is a rivet to rotatably and inseparably connect the base piece 21 and the connecting piece 22. However, for example, a configuration in which the base piece 21 and the connecting piece 22 are rotatably and separably connected by using bolts and nuts for the connecting member 33 may also be adopted. On the other hand, the holding portion 25 that holds the rotational position of the base piece 21 and the connecting piece 22 is configured to be joined by a screw 41 as shown in FIGS. 1 and 3 with one positioning portion 39 selected from a number of positioning portions 39 of the connecting piece 22 and the positioning receiving portion 32 of the base piece 21 being aligned. Moreover, the fixing portion 26 that fixes the base piece 21 and the connecting piece 22 to the power tool 10 is configured in common with the holding portion 25 in this embodiment, and the screw 41 that joins the positioning portion 39 of the connecting piece 22 and the positioning receiving portion 32 of the base piece 21 is fastened to a fixed portion 26 provided in advance on the power tool 10.

[0025] To attach and use the hanging tool 20 configured in this way to the power tool 10, remove an authentic hook or the like from the power tool 10 in advance. The hanging tool 20 rotatably connects the connecting piece 22 and the base piece 21 by the connecting member 33 at the connecting portion 24 and leaves the holding portion 25 and the fixing portion 26 unjoined. At this time, the branch portion 38 of the connecting piece 22 is arranged at one position selected from the two fulcrum receiving portions 31 of the base piece 21.

[0026] In this state, the folding portion 28 of the base piece 21 is locked in a groove 12 provided in advance in the power tool 10. Then, the connecting piece 22 is displaced in the rotational direction with respect to the base piece 21. By selecting an optimal one from a number of positioning portions 39 of the connecting piece 22 and aligning it with one of the two positioning receiving portions 32 of the base piece 21 corresponding to the fulcrum receiving portion 31, the connecting portion 36 of the connecting piece 22 is arranged so as to face in an appropriate direction.

[0027] Then, a screw 41 is inserted through the positioning portion 39 of the aligned connecting piece 22 and the positioning receiving portion 32 of the base piece 21, and fastened and fixed to a fixed portion 26 provided in advance in the power tool 10. As a result, with the connecting portion 36 of the connecting piece 22 arranged at an appropriate position with respect to the power tool 10, the connecting piece 22 and the base piece 21 are held at an appropriate relative position and fixed to the power tool 10.

[0028] Thereafter, for example, by inserting and connecting a suspended portion such as a carabiner worn by an operator on a waist belt or the like into the through opening of the connecting portion 36, the power tool 10 can be suspended from the suspended portion 11 and used.

[0029] According to the suspension tool 20 of the present embodiment as described above, the base piece 21 that can be attached to the power tool 10 and the connecting piece 22 that can be connected to the suspended portion 11 are connected by a connecting portion 24 so as to be displaceable in the rotational direction, and further, the positions of the base piece 21 and the connecting piece 22 in the rotational direction can be held by a holding portion 25, and the base piece 21 and the connecting piece 22 can be fixed to the power tool 10 by a fixing portion 26. Therefore, the base piece 21 and the connecting piece 22 are displaced in the rotational direction according to the center of gravity position of the power tool 10 and the mounting position of the suspension tool provided on the power tool 10, or the base piece 21 and the connecting piece 22 are displaced in the rotational direction according to the work content, the preference of the operator, etc., and by holding and fixing the position, the connecting portion 36 of the connecting piece 22 for connecting to the suspended portion 11 can be arranged at an appropriate position with respect to the power tool 10.

[0030] For example, it can also be used for power tools of other manufacturers in which the positions and orientations of the fixed parts 26 such as screw holes and grooves provided in advance in the power tool 10 are completely different. Even in such a case, it is possible to arrange the connecting piece 22 at an appropriate position. As a result, even if the suspension tool 20 is attached to various power tools 10, the power tool 10 can be suspended at an appropriate position.

[0031] In the suspension tool 20 of the present embodiment, since the base piece 21 that can be attached to the power tool 10 and the connecting piece 22 that can be connected to the suspended part 11 are displaceable in the rotational direction, by displacing the connecting piece 22 in the rotational direction with respect to the base piece 21 attached to a predetermined position of the power tool 10, the position where the connecting piece 22 protrudes from the power tool can be adjusted. Therefore, when the power tool 10 is placed on a flat surface, the connecting piece 22 can be arranged at a position that does not interfere with the flat surface. For example, even if the thickness of the battery of the power tool 10 is different, the angle can be changed so that the connecting piece 22 does not interfere with the ground. Thereby, it is possible to stably place the power tool 10 on a flat surface with the suspension tool 20 attached to the power tool 10.

[0032] In the suspension tool 20 of the present embodiment, if both the base piece 21 and the connecting piece 22 are provided with a fixing part 26 that can be fixed to the power tool 10, even if they are connected so as to be displaceable in the rotational direction with respect to each other, it is possible to prevent the connecting part 24 from being damaged by being loaded with an excessive load during use, and it is easy to ensure sufficient strength of the suspension tool 20.

[0033] In the suspension tool 20 of the present embodiment, if the holding part 25 has a plurality of positioning parts 39 provided in the circumferential direction at a certain distance from the connecting part 24 on the base piece and a positioning receiving part 32 provided at a certain distance from the connecting part 24 on the connecting piece 22 and capable of holding some of the positioning parts 39, it is easy to displace and hold the base piece 21 and the connecting piece 22 in the rotational direction.

[0034] By fixing the positioning part 39 and the positioning receiving part 32 to the fixed part 26 provided on the power tool 10, if the fixed part 26 capable of fixing both the base piece 21 and the connecting piece 22 to the power tool 10 is provided, the base piece 21 and the connecting piece 22 can be fixed to the power tool 10 by using the holding part 25 that displaces and holds them in the rotational direction. Therefore, it is possible to simply provide a structure that can prevent an excessive load from being applied to the connecting part 24 during use and causing damage.

[0035] In the suspension tool 20 of the present embodiment, the connecting part 24 has a fulcrum part 38 provided at the center of a plurality of positioning parts 39 in the connecting piece 22, and a fulcrum receiving part 31 provided on the base piece 21 and capable of connecting the fulcrum part 38 to a plurality of positions. On the other hand, a plurality of positioning receiving parts 32 are provided at a fixed distance from a plurality of positions of the fulcrum receiving part 31. Therefore, by selecting and arranging one location of the fulcrum receiving part 31 for the fulcrum part 38, a plurality of positions of the connecting part 24 between the base piece 21 and the connecting piece 22 can be selected, and the degree of freedom in attaching the suspension tool 20 to the power tool 10 can be improved by displacing the position of the entire connecting piece 22 with respect to the base piece 21.

[0036] Also, since both ends of the fulcrum receiving part 31 of the base piece 21 and the two positioning receiving parts 32 are arranged at target positions with respect to the axis L orthogonal to the folding part 28, if the base piece 21 is arranged on the opposite side of the connecting piece 22 and the folding part 28 is arranged in the opposite direction, the suspension tool 20 can be configured in the opposite orientation. Therefore, the suspension tool 20 can be attached to the opposite side surface of the power tool 10, and it is easy to change between right-handed use and left-handed use.

[0037] In this embodiment, since the fulcrum receiving portion 31 is formed by a long hole in which the fulcrum portion 38 can slide and move, the fulcrum portion 38 can be easily moved between a plurality of fulcrum receiving portions 31, and the position of the connecting portion 24 between the base piece 21 and the connecting piece 22 can be easily changed. Further, while the suspension tool 20 is fixed to the power tool 10 and used, since the positioning portion 39 is held by the positioning receiving portion 32, the fulcrum portion 38 does not move within the long hole, and the position of the connecting portion 24 between the base piece 21 and the connecting piece 22 can be prevented from changing during use, and stable use can be achieved.

[0038] For example, in this embodiment, as shown in FIG. 8(a), with the fulcrum portion 38 of the connecting piece 22 arranged at one end of the fulcrum receiving portion 31 of the base piece 21 and one positioning hole 39a of the positioning portion 39 of the connecting piece 22 arranged in one of the positioning receiving portions 32, the base piece 21 and the connecting piece 22 can be fixed. Further, as shown in FIG. 8(b), with the fulcrum portion 38 of the connecting piece 22 arranged at an intermediate position of the fulcrum receiving portion 31 of the base piece 21 and one positioning hole 39a of the positioning portion 39 of the connecting piece 22 arranged in one of the positioning receiving portions 32, the base piece 21 and the connecting piece 22 can be fixed. By changing the position in this way, when the position of the connecting portion 36 is far from the main body or battery of the power tool 10 and is difficult to use, it can be brought closer.

[0039] It should be noted that the above embodiment can be appropriately changed within the scope of the present invention. For example, in the above embodiment, an example in which the holding portion 25 and the fixing portion 26 are provided in common with the same configuration has been described, but it is not particularly limited, and a configuration for holding the rotational position between the base piece 21 and the connecting piece 22 and a configuration for fixing both the holding portion 25 and the fixing portion 26 to the power tool 10 can be provided separately.

[0040] In the above-described embodiment, an example in which the positioning receiving portion 32 is provided on the base piece 21 and the positioning portion 39 is provided on the connecting piece 22 has been described. However, the positioning portion 39 may be provided on the base piece 21 and the positioning receiving portion 32 may be provided on the connecting piece 22. Further, in the above, the fulcrum portion 38 is provided on the connecting piece 22 and the fulcrum receiving portion 31 is provided on the base piece 21. However, the fulcrum portion 38 may be provided on the base piece 21 and the fulcrum receiving portion 31 may be provided on the connecting piece 22.

[0041] In the above-described embodiment, an example in which the positioning hole 39a of the positioning portion 39 is provided in a range of approximately a half circumference in the circumferential direction centered on the fulcrum portion 38 has been described. However, it is not particularly limited. For example, if the positioning hole 39a is provided over the entire 360-degree circumference centered on the fulcrum portion 38, it is also possible to change the angle over the entire 360-degree circumference. In the above-described embodiment, an example in which the base piece 21 is provided with the fulcrum receiving portion 31 capable of connecting the fulcrum portion 38 at a plurality of positions and a plurality of positioning receiving portions 32 has been described. However, the present invention can also be applied even if the base piece 21 is provided with the fulcrum receiving portion 31 capable of connecting the fulcrum portion 38 at one position and one positioning receiving portion 32.

[0042] Furthermore, in the above, an example in which the connecting piece 22 is formed of a plate-like body has been described. However, as long as the connecting portion 36 of the connecting piece 22 has a shape capable of being connected to the suspended portion 11, it may be formed in a three-dimensional shape. For example, as shown in FIG. 9, it may be bent between the base portion 35 and the connecting portion 36 having a through opening to form an overall hook shape, and the hook-shaped connecting piece 22 may be rotatably connected to the base piece 21 for use. Furthermore, in the above, a steel plate punched by pressing is quenched to give strength and used as the connecting piece 22 made of a plate-like body. However, it is not particularly limited. For example, the base portion 35 and the connecting portion 36 may be formed of different materials and integrated. For example, the base portion 35 of the connecting piece 22 may be formed of a plate material, the connecting portion 36 may be formed of a molded body obtained by bending a round bar having a diameter of about 4 mm to 6 mm, and both may be joined by welding or the like for use.

[0043] [Second Embodiment] FIG. 12 shows a connecting piece in a suspension tool for a power tool according to the second embodiment. The suspension tool 20 of this embodiment is configured in the same manner as the suspension tool 20 of the first embodiment, except that the shape of the connecting piece 42 is different. This connecting piece 42 has an annular connecting portion 36a for passing through and connecting a suspended portion 11 such as a carabiner, and a plug connecting portion 36b that protrudes in a direction different from that of the annular connecting portion 36a and can be inserted into and connected to a suspended portion having a configuration different from that of the suspended portion 11, and is integrally formed. Here, the suspended portion having a configuration different from that of the suspended portion 11 is not particularly limited as long as it is a portion capable of supporting the load of the entire power tool 10 by inserting the plug connecting portion 36b. For example, it may be between the operator's waist belt and clothes.

[0044] Even in the suspension tool 20 of the power tool 10 using such a connecting piece 42, the annular connecting portion 36a can be used in the same manner as the connecting portion 36 of the first embodiment, and the same operational effects as those of the first embodiment can be obtained. Moreover, in the suspension tool 20 of this embodiment, since the connecting piece 42 has a predetermined plug connecting portion 36b together with the annular connecting portion 36a, by passing the suspended portion 11 through the annular connecting portion 36a and connecting it, the power tool 10 can be securely suspended to prevent it from falling. On the other hand, by inserting the plug connecting portion 36b into a suspended portion having a configuration different from that of the suspended portion 11 and connecting it, the power tool 10 can be simply and easily suspended. Therefore, depending on various usage conditions such as the work content, usage environment, and the operator's preference, the operator can appropriately select the suspension method, improving the usability.

[0045] For example, during work, if the plug connecting portion 36b is simply inserted from above between the waist belt and clothes and the power tool 10 is suspended on the waist belt, the operator can use both hands to perform other tasks. In cases where the power tool 10 must absolutely not be dropped, such as during movement or working at heights, by using the annular connecting portion 36a and passing the suspended portion 11 such as the carabiner of the waist belt through the annular connecting portion 36a for suspension, the fall can be surely prevented. Therefore, two functions can be realized with one suspension tool 20.

[0046] FIG. 13 shows a state where the suspension tool of the power tool according to the second embodiment is attached to the power tool. The suspension tool 20 of the present embodiment is attached to a power tool 10 having a grip portion 13 and a main body portion 14 having an output end portion 14a, similar to the first embodiment, and includes a connecting piece 42 and a base piece 21. Note that the method of attaching the connecting piece 42 to the power tool 10 via the base piece 21 is the same as that of the first embodiment, so the description thereof is omitted.

[0047] The connecting piece 42 has a base portion 35 that can be attached to a position away from the main body portion 14 of the grip portion 13, an annular connecting portion 36a, and an insertion connecting portion 36b provided integrally with the base portion 35. The insertion connecting portion 36b protrudes in a direction different from that of the annular connecting portion 36a, and is configured to be inserted into a suspended portion having a configuration different from that of the suspended portion 11 and be suspended. For example, the insertion connecting portion 36b may be suspended from the waist belt 43 by being inserted from above between the waist belt 43 and clothes.

[0048] The connecting piece 42 connects the base portion 35 to the side surface of the grip portion 13, and is fixed by the base piece 21 so that the directions in which the annular connecting portion 36a and the insertion connecting portion 36b protrude form an appropriate angle in the circumferential direction around the base portion 35. Here, the appropriate angle may be, for example, an angle that makes it difficult for the power tool 10 to fall or sway when the power tool 10 is suspended due to the center of gravity of the power tool 10 acting directly downward. In the present embodiment, the insertion connecting portion 36b protrudes toward the main body portion 14 side, and the annular connecting portion 36a protrudes from the grip portion 13. The annular connecting portion 36a protrudes to the side of the grip portion 13 on the side opposite to the output end portion 14a of the main body portion 14 of the grip portion 13. In this way, when the suspended portion 11 is passed through the connecting portion 36 of the suspension tool 20 and suspended, the grip portion 13 is suspended in a slightly inclined state. In this slightly inclined state, it is easier for the operator to grasp the grip portion 13 by hand.

[0049] On the other hand, the insertion connecting piece 42 protrudes obliquely toward the output end portion 14a side from the center of gravity position near the connecting portion between the grip portion 13 and the main body portion 14 of the power tool 10. In this way, when the insertion connecting portion 36b is inserted into the suspended portion such as a waist belt to suspend the power tool 10, the grip portion 13 can be arranged with a slight inclination, so that it is easier for the operator to grasp the grip portion 13 by hand. Further, when the insertion connecting piece 42 is arranged along the grip portion 13, it becomes difficult to insert a finger into the gap between the insertion connecting portion 36b and the grip portion 13, but this can be avoided at this position. Therefore, the operator can easily suspend and remove the power tool 10. Moreover, at this position, it is less likely to get in the way when using the power tool 10, and it is also less likely to get in the way during attachment and detachment.

[0050] [Third Embodiment] FIG. 14 shows a connecting piece in the suspension tool of the power tool according to the third embodiment. Regarding the configurations of the annular connecting portion 36a and the insertion connecting portion 36b of the connecting piece 42 of the suspension tool 20 in the present embodiment, they are the same as the connecting piece 42 shown in the second embodiment. The connecting piece 42 in the third embodiment is different in configuration from the connecting piece 42 shown in the second embodiment in that the folding portion 28 and the fixing hole 39b are provided in the base portion 35. The connecting piece 42 in the third embodiment does not need to be attached to the power tool 10 via the base piece 21. By locking the folding portion 28 provided in the base portion 35 to the groove provided in the power tool 10 and inserting a screw or the like through the fixing hole 39b and fastening it to the fixed portion 26 provided in the power tool 10, the connecting piece 42 can be directly attached to the power tool 10.

[0051] As described above, the suspension tool 20 according to the third embodiment is not displaceable in the rotational direction like the suspension tool 20 shown in the first and second embodiments. However, since the protruding direction of the insertion connection 36b is at an appropriate angle with respect to the annular connection portion 36a, for example, when suspended from the suspended portion 11, it is in a position where it can be easily detached. In addition, since it is suspended obliquely outside the center of gravity of the power tool 10, it becomes easier to grip the grip portion 13 of the power tool 10. Also, regarding the insertion connection portion 36b, when the power tool 10 is inserted into the waist belt, the power tool 10 is in a tilted state, so it is easy to grip the grip portion 13 and it is also easy to attach and detach.

[0052] According to the suspension tool 20 of the power tool 10 as described above, since the annular connection portion 36a and the insertion connection portion 36b are provided on the connection piece 42, by passing the suspended portion 11 through the annular connection portion 36a and connecting them, the power tool 10 can be securely suspended to prevent it from falling. By inserting the insertion connection portion 36b into a suspended portion having a configuration different from that of the suspended portion 11 and connecting them, the power tool 10 can be simply and easily suspended. Therefore, depending on various usage conditions such as the work content, the usage environment, and the preferences of the operator, the operator can properly select the suspension method, improving the usability.

[0053] Furthermore, if the power tool 10 to be fixed is determined, the annular connection portion 36a and the insertion connection portion 36b of the connection piece 42 can be made to protrude in directions suitable for various usage conditions according to the center of gravity position, grip shape, etc. of the power tool 10. Further, by connecting the base portion 35 of the connection piece 42 to the side surface of the grip portion 13 and fixing it with the fixing portion 26, the annular connection portion 36a and the insertion connection portion 36b can be arranged to protrude at angles suitable for their respective functions around the base portion 35. Therefore, depending on various usage conditions such as the usage environment and the preferences of the operator, the operator can properly select the suspension method to improve the usability.

[0054] In addition, in each of the above embodiments, within the scope of the present invention, in addition to being appropriately changeable as described above, the connection piece 42 of the second and third embodiments can also be further changed. For example, in the above description, the annular connecting portion 36a and the insertion connecting portion 36b of the connecting piece 42 were formed in a flat plate shape, but it is not particularly limited. For example, with respect to the base portion 35 connected to the power tool 10, the annular connecting portion 36a and the insertion connecting portion 36b may be formed in a three-dimensional shape so as to be offset in the plate thickness direction. In the above embodiment, an example in which the annular connecting portion 36a and the insertion connecting portion 36b are provided on one connecting piece 42 has been described. However, they may be provided on separate connecting pieces 42 and attached to the same power tool 10. In this way, the protruding directions of each can be adjusted separately.
