[0043] The utility model provides a kind of hook structure 100 and including the portable tool 1000 of hook structure 100. Please refer to Figure 1 And Figure 2 , the portable tool 1000 includes machine shell 200 and installs hook structure 100 on machine shell 200, wherein machine shell 200 constitutes the external contour of portable tool 1000, hook structure 100 makes portable tool 1000 can be hung up. The portable tool 1000 is not limited to hand tool or electric tool, when portable tool 1000 is electric tool, power supply, power driving device etc. can be further arranged in machine shell 200, the external portion of machine shell 200 can be arranged power output device with power driving device transmission connection. In alternative embodiment, portable tool 1000 can be screwdriver, spanner, electric drill, electric hammer etc.

[0044] As Figure 1 And Figure 2 Show, in an embodiment, with the portable tool 1000 as electric wrench as example is explained, wherein machine shell 200 includes head end and handle, wherein head end can be installed with the work head of suitable specification according to need, and machine shell 200 is provided with motor, transmission mechanism etc. for driving work head rotation in it. Handle is used for operator to hold when using, so work head direction can be flexibly adjusted according to the object of need operation.

[0045] The hook structure 100 can be arranged at any position on the casing 200, and in a preferred embodiment, the hook structure 100 is arranged at one end of the handle, specifically on the battery pack mounting portion at one end of the handle, so that the head end is relatively far away from the hanging object, and the working head of the head end is avoided to cause injury to the operator wearing the hanging object. The hook structure 100 has a hanging groove 120 for hanging the portable tool 1000, and the specific shape and size of the hanging groove 120 are not limited, which can be matched with the belt, clothes and the like of the operator, so as to facilitate the operator to hang the portable tool 1000 on the operator's body during work interval, for example, on the belt or backpack of the operator, so as to facilitate the operator to replace other tools or carry the tool when working. In addition, the hook structure 100 can also cooperate with the hanging parts on the building wall surface, in the storage cabinet or in the tool box, so that the portable tool 1000 can be conveniently hung and stored.

[0046] In the embodiment, please refer to Figures 3 to 5 The hook structure 100 is fixed on the casing 200 through the locking and matching connection of the locking member 20 and the locking matching member 60, and the locking member 20 and the locking matching member 60 are specifically a thread locking mechanism matched with each other, wherein the locking member 20 is arranged on the hook structure 100, and the locking matching member 60 is arranged on the casing 200. Specifically, one of the locking member 20 and the locking matching member 60 can be rotated around an axial extending rotation shaft, and then screwed into the other one of the locking member 20 and the locking matching member 60, so that the hook structure 100 is fixedly installed on the casing 200. As shown in Figure 6 and Figure 7 The specific structure of the locking member 20 and the locking matching member 60 is not limited, for example, it can be a matched bolt and nut, or a cam and fixed seat and the like.

[0047] It can be understood that since the locking member 20 and the locking matching member 60 are locked and fixed by rotation, there is a possibility of rotation and loosening between the two, especially during the long time use of the portable tool 1000, the locking member 20 and the locking matching member 60 are constantly subjected to external force and produce rotational displacement, the connection and fixation between the hook structure 100 and the casing 200 is no longer reliable, which can cause the portable tool 1000 to suddenly fall, causing tool damage and even injuring personnel and equipment.

[0048] Therefore, the hook structure 100 provided by the utility model has the following structure: please refer to Figure 8 and Figure 9The hook structure 100 comprises a main body 10, and the main body 10 is provided with a mounting portion 11 and a hanging portion 12. Specifically, the main body 10 can be connected and fixed as a whole or integrally formed. In the embodiment, the main body 10 is integrally formed by a sheet-shaped metal material, thereby having the advantages of convenient manufacturing and strong durability. The mounting portion 11 and the hanging portion 12 can be connected and fixed on the main body 10 as components provided separately from the main body 10, or integrally formed with the main body 10. Preferably, the mounting portion 11, the hanging portion 12 and the main body 10 are integrally formed, wherein the mounting portion 11 is used to connect and cooperate with the locking piece 20 to fix the hook structure 100 to the cabinet 200, and the hanging portion 12 is used to form a hanging groove 120 so that the portable tool 1000 can be hung.

[0049] Further, please refer to Figures 7 to 9 The mounting portion 11 comprises a pad plate 111 and a supporting leg 112. The pad plate 111 is provided in a plate shape. In the embodiment, the pad plate 111 is made of a material with high strength and certain elasticity, for example, aluminum or steel. The pad plate 111 has a first side 1111 and a second side 1112 oppositely arranged in the axial direction. It should be noted that in the description of the axial direction and the radial direction in the embodiment, the axial direction is specifically the extension direction of the rotation axis of the locking piece 20 when the locking piece 20 is screwed into the locking fitting piece 60, and the radial direction is opposite to the axial direction, specifically the direction extending outward from the axis of the rotation axis and perpendicular to the axial direction.

[0050] The pad plate 111 is provided with a mounting hole 1110 penetrating the first side 1111 and the second side 1112 in the axial direction. The mounting hole 1110 is used for the locking piece 20 to pass through. As shown in Figure 7 The supporting leg 112 protrudes from the first side 1111 and is used to abut against the cabinet 200 of the portable tool 1000, so that the pad plate 111 and the cabinet 200 form an assembly gap 30. The locking piece 20 passes through the mounting hole 1110 and is screwed into the locking fitting piece 60 provided on the inner side of the cabinet 200. Specifically, as shown in Figure 5 The cabinet 200 is provided with a through hole 40, and the locking fitting piece 60 is arranged on the inner side of the cabinet 200 and coaxially arranged with the through hole 40. That is, the locking piece 20 is sequentially inserted into the mounting hole 1110 and the through hole 40, sequentially passes through the pad plate 111 and the cabinet 200, and is screwed into the locking fitting piece 60 provided on the inner side of the cabinet 200 and threadedly cooperates with the locking fitting piece 60 to play a fastening role. That is, the hook structure 100 and the cabinet 200 are mainly connected and fixed by the thread cooperation between the locking piece 20 and the locking fitting piece 60.

[0051] In this embodiment, in order to strengthen the locking force between the locking member 20 and the locking cooperating member 60, the locking member 20 further presses against the second side 1112 of the pad 111, so that the pad 111 is elastically deformed to bend towards the first side 1111 during the process of the locking member 20 being screwed into the locking cooperating member 60. Specifically, the end of the locking member 20 away from the locking cooperating member 60 is provided with a pressing portion 21, and the outer diameter of the pressing portion 21 is greater than the outer diameter of the portion of the locking member 20 that cooperates with the locking cooperating member 60. The pressing portion 21 is provided with an operating structure that can cooperate with an operating tool, so that the locking member 20 can be operated to rotate, for example, the end of a bolt is provided with a nut.

[0052] In this embodiment, the pressing portion 21 presses against the pad 111 that has elasticity, so that the pad 111 is elastically deformed to bend towards the casing 200. In this way, the pad 111 plays a role of protecting the casing 200 from being directly pressed by the pressing force of the pressing portion 21, and the stress inside the casing 200 is dispersed, so that the casing 200 is not easily deformed or damaged by the pressing. On the other hand, the elastically deformed pad 111 provides an axial reaction force for the locking member 20, and the axial reaction force acts on the cooperating structure between the locking member 20 and the locking cooperating member 60, so that the friction between the two is increased, thereby increasing the locking force between the locking member 20 and the locking cooperating member 60, and effectively preventing loosening.

[0053] It can be understood that the shape and structure of the leg 112 are not limited. In this embodiment, the number of the legs 112 is at least two, and the at least two legs 112 are distributed around the outer periphery of the mounting hole 1110. In this way, the at least two legs 112 uniformly support the pad 111, so that the casing 200 is uniformly stressed.

[0054] Further, referring to FIGS. 3 and Figure 4 The casing 200 is formed with a limiting structure 50 on the outside, and the limiting structure 50 acts on the leg 112 to limit the displacement of the leg 112 in the radial direction relative to the casing 200. In this way, when the pad 111 is pressed and bent by the pressing portion 21 towards the casing 200, the leg 112 is limited to displace outwardly, so as to avoid the displacement of the pad 111 in the radial direction relative to the casing 200. In addition, when the hook structure 100 is assembled, the limiting action between the leg 112 and the limiting structure 50 can also achieve the pre-positioning of the main body, so as to ensure the coaxiality of the mounting hole 1110, the through hole 40 and the locking cooperating member 60, thereby enabling the locking member 20 to be more simply inserted into the mounting hole 1110 and the through hole 40, and enhancing the assembly efficiency.

[0055] The specific shape and size of the limiting structure 50 can be designed according to the size, shape and position of the leg 112. In alternative embodiments, referring to FIG. 4, Figures 11 to 13The two supporting legs 112 are arranged in a spaced apart manner in the lateral direction, each of the two limiting grooves 51 has a first limiting surface 511 abutting against the corresponding supporting leg 112 in the lateral direction, and each of the two limiting grooves 51 has an open end in the longitudinal direction. In this way, when the two supporting legs 112 are inserted into the two limiting grooves 51 respectively, the base plate 111 can be relatively moved in the longitudinal direction with respect to the casing 200 before or during the assembly, so as to align the mounting hole 1110 with the through hole 40. This structure has a relatively low requirement on the forming precision of the main body and the casing 200, and is convenient for manufacturing.

[0056] In the optional first embodiment of the limiting structure 50, please refer to Figure 10 and Figure 11 The two supporting legs 112 are arranged in a spaced apart manner in the lateral direction, each of the two limiting grooves 51 has a first limiting surface 511 abutting against the corresponding supporting leg 112 in the lateral direction, and each of the two limiting grooves 51 has an open end in the longitudinal direction. In this way, when the two supporting legs 112 are inserted into the two limiting grooves 51 respectively, the base plate 111 can be relatively moved in the longitudinal direction with respect to the casing 200 before or during the assembly, so as to align the mounting hole 1110 with the through hole 40. This structure has a relatively low requirement on the forming precision of the main body and the casing 200, and is convenient for manufacturing.

[0057] In the optional first embodiment of the limiting structure 50, please refer to Figure 12 and Figure 13 The two supporting legs 112 are arranged in a spaced apart manner in the lateral direction, each of the two limiting grooves 51 has a first limiting surface 511 abutting against the corresponding supporting leg 112 in the lateral direction, and each of the two limiting grooves 51 has an open end in the longitudinal direction. In this way, when the two supporting legs 112 are inserted into the two limiting grooves 51 respectively, the base plate 111 can be relatively moved in the longitudinal direction with respect to the casing 200 before or during the assembly, so as to align the mounting hole 1110 with the through hole 40. This structure has a relatively low requirement on the forming precision of the main body and the casing 200, and is convenient for manufacturing.

[0058] It should be noted that in the above two embodiments, the lateral direction and the longitudinal direction are both parallel to the radial direction and intersect with each other.

[0059] Preferably, the limiting structure 50 can be formed by forming a first protrusion 41 and two second protrusions 42 on the outer side of the casing 200, the two second protrusions 42 are arranged on the two sides of the first protrusion 41 in the radial direction, and each of the two second protrusions 42 and the first protrusion 41 defines a limiting groove 51. The first protrusion 41 and the second protrusion 42 are both protruded from the outer surface of the casing 200, and are preferably formed integrally with the casing 200.

[0060] Further, the inner side of the casing 200 is formed with a mounting groove 411 corresponding to the region of the first boss 41, the through hole 40 is formed in the bottom of the mounting groove 411, and the locking fitting member 60 is pre-installed in the mounting groove 411 and does not protrude beyond the inner surface of the casing 200. Specifically, the locking fitting member 60 can be pre-installed in the mounting groove 411 by interference fit or insert injection molding. In this way, when the hook structure 100 is installed, the locking fitting member 60 has already been pre-installed on the inner side of the casing 200, and there is no need to additionally position or fix the locking fitting member 60, which is simple to assemble and improves the assembly efficiency of the hook structure 100.

[0061] On the basis of the above-mentioned embodiments, referring to Figure 8 and Figure 9 , the hanging part 12 comprises a first plate member 121, a connecting plate member 123 and a second plate member 122 connected in sequence, and the three plate members are integrally arranged, wherein the first plate member 121 is arranged adjacent to the mounting part 11, the second plate member 122 has the same extension direction as the first plate member 121, and the second plate member 122 is arranged spaced apart from the first plate member 121, the connecting plate member 123 is arranged extending between the first plate member 121 and the second plate member 122, and the first plate member 121, the second plate member 122 and the connecting plate member 123 collectively enclose to form a hanging groove 120, and the opening of the hanging groove 120 is arranged opposite to the connecting plate member 123. In this way, the hanging groove 120 is formed by the bent plate members, which is simple in structure, durable and low in manufacturing cost.

[0062] Further, the second plate member 122 protrudes beyond the first plate member 121 in the direction close to the opening, so that when the hanging part 12 is hung on the belt, the second plate member 122 can be inserted into the belt, which is simple to operate and not easy to make mistakes. Preferably, the end of the second plate member 122 close to the opening is bent and extends in the axial direction away from the first plate member 121. On the one hand, the second plate member 122 is more easily inserted into the belt, and on the other hand, the bent shape makes the end of the second plate member 122 have a certain curvature, which is not easy to scratch the operator.

[0063] Optionally, the projection of the second plate member 122 in the axial direction covers the mounting part 11, and the second plate member 122 is formed with a relief opening 1221, and the projection of the relief opening 1221 in the axial direction at least covers the locking member 21. Here, the "projection" refers to the projection of the outer contour of the component. In this embodiment, the provision of the relief opening 1221 allows the operating tool to be inserted through the relief opening 1221 and act on the pressing part 21 when assembling the portable tool 1000, thereby facilitating the rotation of the locking member 20 and allowing the locking member 20 to be screwed into the locking fitting member 60.

[0064] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, other different forms of changes or variations can be made by those skilled in the art without creative labor, and all should belong to the protection scope of the present application.
