In the related art, for hexagon screws / bolts of different models, different models of hexagon wrenches are required. Such a large number of models of hexagon wrenches occupy a large amount of space when stored and are not easy to place. When in use, different models of hexagon wrenches need to be selected according to different models of hexagon screws / bolts for carrying. It is easy to forget one or several models of hexagon wrenches when carrying, and the number of hexagon wrenches to be carried is relatively large. In short, such a large number of models of hexagon wrenches are very inconvenient in storage, use, and carrying, thus reducing the user experience. Summary of the Utility Model
[0003] This application provides a nested hexagon wrench, aiming to solve the problem that a number of hexagon wrenches of different models are inconvenient in storage, use, and carrying in the related art.
[0004] To solve the above-mentioned drawbacks existing in the related art, this application provides a nested hexagon wrench, which includes a main hexagon wrench assembly. The main hexagon wrench assembly includes a pin, an outer hexagon wrench, and a plurality of inner hexagon wrenches. The lengths of the plurality of inner hexagon wrenches are the same. The outer hexagon wrench has a blind hole along its own axis direction, and the inner hexagon wrench has a through hole along its own axis direction. The volumes of the outer hexagon wrench and the plurality of inner hexagon wrenches decrease in sequence, and the volumes of the corresponding blind hole and the plurality of through holes decrease in sequence. The blind hole and the through hole are both used to accommodate an inner hexagon wrench whose volume is adapted to its own volume. Wherein, an outer receiving hole communicating with the blind hole is formed on the outer wall of the outer hexagon wrench, inner receiving holes and fixing holes are formed on opposite sides of the inner hexagon wrench. The inner receiving holes communicate with the through hole and are spaced apart, and the fixing holes are located at positions far from the hole mouth. Specifically, the nested hexagon wrench has a storage state and a use state. In the storage state, the pin is inserted into the aligned outer receiving hole and the plurality of inner receiving holes to limit the plurality of inner hexagon wrenches in the blind hole. In the use state, the pin is inserted into the aligned outer receiving hole, the fixing hole of the target inner hexagon wrench, and the inner receiving holes of the remaining inner hexagon wrenches to expose the end of the target inner hexagon wrench outside the blind hole and limit the remaining inner hexagon wrenches in the blind hole.
[0005] In some implementation solutions, the length of the blind hole is greater than or equal to the length of the inner hexagon wrench.
[0006] In some implementations, the nested hex key further includes two handles, which are respectively arranged on opposite sides of the outer hex key, and both handles are located at positions far from the hole opening; wherein, the two handles are used to transfer the force applied by the user to the outer hex key in the use state, so that the outer hex key drives each inner hex key inside to rotate synchronously around its own axis.
[0007] As one of the implementations, the handle includes a base and a joystick. The base is arranged on the outer wall of the outer hex key, and one end of the joystick is arranged on the base and rotatably connected to the base; wherein, in the storage state, the axis of the joystick is parallel to the axis of the outer hex key; in the use state, the axis of the joystick is perpendicular to the axis of the outer hex key. Further, the base includes a bottom plate and two opposite side plates. The two side plates are respectively located on both sides of the axis of the outer hex key. The bottom plate is connected between the ends of the two side plates close to the hole opening. One end of the joystick is located between the two side plates and is rotatably matched with the two side plates through a rotating shaft.
[0008] In some implementations, the outer hex key has a connection end far from the hole opening. The nested hex key further includes a secondary hex key assembly with the same structure as the main hex key assembly. The connection ends of the outer hex keys in the main hex key assembly and the secondary hex key assembly are connected to each other. As one of the implementations, the connection end of the outer hex key in the main hex key assembly is provided with a slot, and the connection end of the outer hex key in the secondary hex key assembly is provided with a buckle that matches the slot.
[0009] Further, the nested hex key further includes a first fixing ring and a first flexible connecting piece. The first fixing ring is arranged on the outer wall of the outer hex key in the main hex key assembly, and the first fixing ring is located at a position far from the hole opening of the outer hex key in the main hex key assembly. One end of the first flexible connecting piece is connected to the first fixing ring, and the other end is connected to the pin in the main hex key assembly; the nested hex key further includes a second fixing ring and a second flexible connecting piece. The second fixing ring is arranged on the outer wall of the outer hex key in the main hex key assembly and is located at a position close to the secondary hex key assembly. One end of the second flexible connecting piece is connected to the second fixing ring, and the other end is connected to the pin in the secondary hex key assembly. Among them, both the first flexible connecting piece and the second flexible connecting piece include chains.
[0010] For the nested hexagon wrench provided by the present application, it includes a main hexagon wrench assembly. The main hexagon wrench assembly includes a pin, an outer hexagon wrench, and a plurality of inner hexagon wrenches. The outer hexagon wrench has a blind hole along its own axis direction, and the inner hexagon wrench has a through hole along its own axis direction. The plurality of inner hexagon wrenches are nested together and placed in the blind hole of the outer hexagon wrench. An outer receiving hole communicating with the blind hole is formed on the outer wall of the outer hexagon wrench. Inner receiving holes and fixing holes that communicate with the through hole and are spaced apart are formed on both opposite sides of the inner hexagon wrench. Both the outer receiving hole and the inner receiving hole are located at positions close to the orifice of the blind hole, and the fixing hole is located at a position far from the orifice. Based on this, in the storage state, the pin can be inserted into the aligned outer receiving hole and a plurality of inner receiving holes, so that the plurality of inner hexagon wrenches are limited in the blind hole; in the use state, the pin can be inserted into the aligned outer receiving hole, the fixing hole of the target inner hexagon wrench, and the inner receiving holes of the remaining inner hexagon wrenches, so that the end of the target inner hexagon wrench is exposed outside the blind hole, and the remaining inner hexagon wrenches are limited in the blind hole. It can be seen that in the present application, a large number of inner hexagon wrenches of different models are nested together and placed in the blind hole of the outer hexagon wrench. When stored, it occupies little space and is easy to place. When in use, there is no need to select different models of hexagon wrenches for different models of hexagon screws / bolts for carrying. When carrying, only one nested hexagon wrench needs to be carried, and there is no need to carry several independent hexagon wrenches, thereby improving the convenience of a plurality of inner hexagon wrenches of different models in storage, use, and carrying, and further improving the user experience.

Detailed implementation manners
[0016] In the related art, for hexagon screws / bolts of different models, hexagon wrenches of different models are required. Such a large number of hexagon wrenches take up a large amount of space and are not easy to place when stored. When in use, different models of hexagon wrenches need to be selected according to different models of hexagon screws / bolts for carrying. It is easy to forget one or several models of hexagon wrenches when carrying, and the number of hexagon wrenches to be carried is relatively large. That is to say, such a large number of hexagon wrenches are very inconvenient in storage, use and carrying, thus reducing the user experience.
[0017] In view of this, the present application proposes a nested hexagon wrench in the following embodiments. It nests a large number of hexagon wrenches of different models (including internal hexagon wrenches and external hexagon wrenches) together. It takes up little space and is easy to place when stored. When in use, there is no need to select different models of hexagon wrenches according to different models of hexagon screws / bolts for carrying. When carrying, only one nested hexagon wrench needs to be carried, rather than carrying several independent hexagon wrenches. That is to say, the nested hexagon wrench is more convenient in storage, use and carrying.
[0018] In order to make the purpose, technical solutions and advantages of the present application more obvious and understandable, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. It should be understood that the following described embodiments of the present application are only used to explain the present application and are not used to limit the present application. That is, based on the various embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical features involved in the following described embodiments of the present application can be combined with each other as long as they do not conflict with each other.
[0019] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which is a schematic structural diagram of the nested hexagon wrench.Figure 2 is a half-sectional view of a nested hex key, Figure 3 is a top view of the nested hex key. This embodiment provides a nested hex key, which includes a main hex key assembly 100. The main hex key assembly 100 includes a pin 110, an outer hex key 120, and a plurality of inner hex keys 130. The lengths of the plurality of inner hex keys 130 are the same. The outer hex key 120 has a blind hole 121 along its own axis direction, and the inner hex key 130 has a through hole 131 along its own axis direction. The volumes of the outer hex key 120 and the plurality of inner hex keys 130 decrease in sequence, and the volumes of the corresponding blind hole 121 and the plurality of through holes 131 also decrease in sequence. The blind hole 121 and the through hole 131 are both used to accommodate the inner hex key 130 whose volume is adapted to its own volume. That is to say, for the plurality of inner hex keys 130, the inner hex key 130 with the largest volume is placed in the blind hole 121, the inner hex key 130 with the second largest volume is placed in the through hole 131 of the inner hex key 130 with the largest volume, the inner hex key 130 with the third largest volume is placed in the through hole 131 of the inner hex key 130 with the second largest volume, and so on. Generally speaking, after nesting the plurality of inner hex keys 130 together, they are placed in the blind hole 121 of the outer hex key 120. In addition, for the models of the outer hex key 120 and the inner hex key 130, they can include any common models of the internal hex keys in the art, such as 5mm, 8mm, 13mm, 4mm, 6mm, 10mm, etc., and can be specifically selected according to actual needs. This application does not make a unique limitation on this.
[0020] It should be noted that whether it is the outer hexagonal wrench 120 or the inner hexagonal wrench 130, they are essentially hexagonal wrenches, and their ends are the working ends, both used to turn hexagonal screws / bolts. It should also be noted that for the outer hexagonal wrench 120, its end can be inserted into the inner hexagonal hole of the inner hexagonal screw / bolt and the outer hexagonal wrench 120 can be rotated to achieve the turning of the inner hexagonal screw / bolt, or the blind hole 121 can be used to wrap the hexagonal head of the outer hexagonal screw / bolt and the outer hexagonal wrench 120 can be rotated to achieve the turning of the outer hexagonal screw / bolt; for the inner hexagonal wrench 130, its end can be inserted into the inner hexagonal hole of the inner hexagonal screw / bolt and the inner hexagonal wrench 130 can be rotated to achieve the turning of the inner hexagonal screw / bolt, or the through hole 131 can be used to wrap the hexagonal head of the outer hexagonal screw / bolt and the inner hexagonal wrench 130 can be rotated to achieve the turning of the outer hexagonal screw / bolt; that is to say, whether it is the outer hexagonal wrench 120 or the inner hexagonal wrench 130, it can be used as an inner hexagonal wrench or an outer hexagonal wrench. In addition, since the inner hexagonal wrench 130 has two opposite ends and its through hole 131 runs through from one end to the other end, each end of the inner hexagonal wrench 130 can be used as an inner / outer hexagonal wrench. When one of the ends is damaged, the other end can be replaced to act as an inner / outer hexagonal wrench; for the outer hexagonal wrench 120, although it also has two opposite ends, since its blind hole 121 is not through, only one end can be used as an inner / outer hexagonal wrench, and the other end can only be used as an inner hexagonal wrench.
[0021] Specifically, an outer receiving hole 1211 communicating with the blind hole 121 is formed on the outer wall of the outer hexagonal wrench 120. Inner receiving holes 1311 and fixing holes 1312 which are communicated with the through hole 131 and spaced apart are formed on both opposite sides of the inner hexagonal wrench 130. The outer receiving hole 1211 and the inner receiving holes 1311 are both located near the orifice of the blind hole 121, while the fixing holes 1312 are located at a position far from the orifice of the blind hole 121. In addition, it should be noted that the length of the inner hexagonal wrench 130 can be greater than the blind hole 121 of the outer hexagonal wrench 120, can be equal to the blind hole 121 of the outer hexagonal wrench 120, or can be less than the blind hole 121 of the outer hexagonal wrench 120, but it is preferably less than or equal to the blind hole 121 of the outer hexagonal wrench 120. In order to ensure the aesthetics of the nested hexagonal wrench and the stability when turning the hexagonal screw or hexagonal bolt, it is further preferably equal to the blind hole 121 of the outer hexagonal wrench 120.
[0022] In practical applications, the nested hex key of this embodiment has two states, namely the storage state and the use state. In the storage state, the outer receiving hole 1211 is aligned with a plurality of inner receiving holes 1311, and the pin 110 is inserted into the outer receiving hole 1211 and the plurality of inner receiving holes 1311. At this time, the plurality of inner hex keys 130 are limited within the blind hole 121 of the outer hex key 120, thereby realizing the storage of the nested hex key. In the use state, taking the target inner hex key among the plurality of inner hex keys 130 as an example, the pin 110 is pulled out from the outer receiving hole 1211 and the plurality of inner receiving holes 1311, and the end of the target inner hex key is moved out of the blind hole 121, so that the outer receiving hole 1211, the fixing hole 1312 of the target inner hex key, and the inner receiving holes 1311 of the remaining inner hex keys 130 are aligned. Then, the pin 110 is inserted into the outer receiving hole 1211, the fixing hole 1312 of the target inner hex key, and the inner receiving holes 1311 of the remaining inner hex keys 130. At this time, the end of the target inner hex key is exposed outside the blind hole 121 for screwing the target hex screw / bolt, while the remaining inner hex keys 130 are limited within the blind hole 121 of the outer hex key 120, thereby realizing the use of the target inner hex key.
[0023] As can be seen from the above, in this application, a plurality of inner hex keys 130 of different models are nested together and then placed in the blind hole 121 of the outer hex key 120. When storing, it occupies little space and is easy to place. When using, there is no need to select different models of hex keys for different models of hex screws / bolts for carrying. When carrying, only one nested hex key needs to be carried, and there is no need to carry several independent hex keys, thereby improving the convenience of storing, using, and carrying several hex keys of different models, and further enhancing the user experience. In addition, the nested hex key of this application has a simple structure and is easy to manufacture. For the damaged outer hex key 120 or inner hex key 130, it is also easy to replace.
[0024] In some embodiments, still referring to Figure 1 、 Figure 2 and Figure 3, in addition to the structure described above, the nested hex key further includes two handles 700. The two handles 700 are respectively disposed on opposite sides of the outer hex key 120, and both of the two handles 700 are located at positions away from the orifice of the blind hole 121. In actual applications, the user can rotate the outer hex key 120 through the two handles 700, so that the outer hex key 120 drives each of the inner hex keys 130 inside to rotate synchronously around its own axis, thereby realizing the screwing of the hexagon screw / bolt; that is to say, the two handles 700 can transfer the force applied by the user to the outer hex key 120 in the use state, so that the outer hex key 120 drives each of the inner hex keys 130 inside to rotate synchronously around its own axis.
[0025] As one of the embodiments, the handle 700 includes a base 710 and a joystick 720. The base 710 is disposed on the outer wall of the outer hex key 120, and one end of the joystick 720 is disposed on the base 710 and is rotatably connected to the base 710. In actual applications, when in the storage state, the joystick 720 can be stored by rotating the joystick 720 relative to the base 710, that is, by rotating the joystick 720 relative to the base 710, the joystick 720 is attached to the outer wall of the outer hex key 120. At this time, the axis of the joystick 720 is parallel to the axis of the outer hex key 120; when in the use state, the joystick 720 can be rotated away from the outer hex key 120, so that the joystick 720 is perpendicular to the outer wall of the outer hex key 120. At this time, the axis of the joystick 720 is also perpendicular to the axis of the outer hex key 120. In this way, it is convenient for the user to apply a force around the axis of the outer hex key 120 on the two joysticks 720, and drive the outer hex key 120 and each of the inner hex keys 130 inside to rotate synchronously around its own axis through the two joysticks 720. Preferably, both opposite ends of the joystick 720 are semi-circular surfaces, and its overall shape is a prism with rounded corners on all four sides.
[0026] In this embodiment, the base 710 includes a bottom plate 711 and two opposite side plates 712. The bottom plate 711 and the two side plates 712 are both disposed on the outer wall of the outer hexagonal wrench 120. The two side plates 712 are respectively located on opposite sides of the axis of the outer hexagonal wrench 120. The bottom plate 711 is connected between the ends of the two side plates 712 close to the orifice of the blind hole 121. One end of the operating rod 720 is located between the two side plates 712 and is rotatably engaged with the two side plates 712 through a rotating shaft. It can be understood that the function of the bottom plate 711 is to limit the rotation angle of the operating rod 720. Connecting the bottom plate 711 between the ends of the two side plates 712 close to the orifice of the blind hole 121 can make the maximum rotation angle of the operating rod 720 be 90°, that is, the operating rod 720 can only rotate to a position perpendicular to the outer wall of the outer hexagonal wrench 120 at most. In this way, when the user applies a force around the axis of the outer hexagonal wrench 120 on the two operating rods 720, unnecessary rotation of the two operating rods 720 can be avoided, thereby affecting the screwing of the hexagon screw / bolt.
[0027] As mentioned above, one end of the outer hexagonal wrench 120 away from the orifice of the blind hole 121 can only be used as an inner hexagonal wrench. For the sake of convenience of description, this end is defined as the connecting end. In some embodiments, still referring to Figure 1 , Figure 2 and Figure 3 , in addition to the structure given above, the nested hexagonal wrench further includes a secondary hexagonal wrench assembly 200 having the same structure as the main hexagonal wrench assembly 100. The connecting ends of the two outer hexagonal wrenches 120 in the main hexagonal wrench assembly 100 and the secondary hexagonal wrench assembly 200 are connected to each other. It can be understood that since the secondary hexagonal wrench assembly 200 has the same structure as the main hexagonal wrench assembly 100, the secondary hexagonal wrench assembly 200 also includes an outer hexagonal wrench 120 and a plurality of inner hexagonal wrenches 130 nested therein. By adding the secondary hexagonal wrench assembly 200, the types and quantities of the hexagonal wrenches included in the nested hexagonal wrench can be greatly increased, thereby enhancing the adaptability of the nested hexagonal wrench to different usage scenarios.
[0028] As one of the embodiments, a slot is provided at the connecting end of the outer hexagonal wrench 120 in the main hexagonal wrench assembly 100, and a buckle matching the slot is provided at the connecting end of the outer hexagonal wrench 120 in the sub-hexagonal wrench assembly 200. That is to say, the connecting ends of the two outer hexagonal wrenches 120 in the main hexagonal wrench assembly 100 and the sub-hexagonal wrench assembly 200 are connected through the snap-fit of the slot and the buckle. In actual applications, although the two handles 700 are configured in the main hexagonal wrench assembly 100, since the connecting ends of the two outer hexagonal wrenches 120 in the main hexagonal wrench assembly 100 and the sub-hexagonal wrench assembly 200 are connected, when the user needs to use the hexagonal wrench in the sub-hexagonal wrench assembly 200, the outer hexagonal wrench 120 in the main hexagonal wrench assembly 100 can be driven to rotate by the two handles 700. When the outer hexagonal wrench 120 in the main hexagonal wrench assembly 100 rotates, it will drive the outer hexagonal wrench 120 in the sub-hexagonal wrench assembly 200 and each inner hexagonal wrench 130 inside to rotate synchronously.
[0029] Furthermore, in addition to the structure described above, the nested hexagonal wrench further includes a first fixing ring 300, a first flexible connecting member 400, a second fixing ring 500, and a second flexible connecting member 600. The first fixing ring 300 is disposed on the outer wall of the outer hexagonal wrench 120 in the main hexagonal wrench assembly 100, and the first fixing ring 300 is located at a position away from the orifice of the blind hole 121 of the outer hexagonal wrench 120 in the main hexagonal wrench assembly 100. One end of the first flexible connecting member 400 is connected to the first fixing ring 300, and the other end is connected to the pin 110 in the main hexagonal wrench assembly 100; the second fixing ring 500 is disposed on the outer wall of the outer hexagonal wrench 120 in the main hexagonal wrench assembly 100 and is located near the sub-hexagonal wrench assembly 200. The second fixing ring 500 is adjacent to the first fixing ring 300. One end of the second flexible connecting member 600 is connected to the second fixing ring 500, and the other end is connected to the pin 110 in the sub-hexagonal wrench assembly 200. It can be understood that by connecting the pin 110 in the main hexagonal wrench assembly 100 through the first fixing ring 300 and the first flexible connecting member 400, and connecting the pin 110 in the sub-hexagonal wrench assembly 200 through the second fixing ring 500 and the second flexible connecting member 600, the loss of the pins 110 in the main hexagonal wrench assembly 100 and the sub-hexagonal wrench assembly 200 can be effectively prevented. Preferably, both the first flexible connecting member 400 and the second flexible connecting member 600 include any one of a chain, a rope, an elastic cord, a plastic wire, and a wire rope.
[0030] The above embodiments are only the preferred implementations of the present application, and they are not the only limitations on the content related to the nested hexagon wrench; in this regard, those skilled in the art can flexibly set according to the actual application scenarios on the basis of the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, at least the main hexagon wrench assembly 100 constitutes a nested hexagon wrench. The main hexagon wrench assembly 100 includes a pin 110, an outer hexagon wrench 120, and a plurality of inner hexagon wrenches 130. The outer hexagon wrench 120 has a blind hole 121 along its own axis direction, and the inner hexagon wrench 130 has a through hole 131 along its own axis direction. After a plurality of inner hexagon wrenches 130 are nested together, they are placed in the blind hole 121 of the outer hexagon wrench 120. An outer receiving hole 1211 communicating with the blind hole 121 is formed on the outer wall of the outer hexagon wrench 120. Both opposite sides of the inner hexagon wrench 130 are provided with inner receiving holes 1311 and fixing holes 1312 that communicate with the through hole 131 and are spaced apart. The outer receiving hole 1211 and the inner receiving hole 1311 are both located near the orifice of the blind hole 121, and the fixing hole 1312 is located away from the orifice. Based on this, in the storage state, the pin 110 can be inserted into the aligned outer receiving hole 1211 and a plurality of inner receiving holes 1311, so that a plurality of inner hexagon wrenches 130 are limited in the blind hole 121; in the use state, the pin 110 can be inserted into the aligned outer receiving hole 1211, the fixing hole 1312 of the target inner hexagon wrench, and the inner receiving holes 1311 of the remaining inner hexagon wrenches 130, so that the end of the target inner hexagon wrench is exposed outside the blind hole 121 and the remaining inner hexagon wrenches 130 are limited in the blind hole 121. It can be seen that the present application nests a large number of inner hexagon wrenches 130 of different models together and places them in the blind hole 121 of the outer hexagon wrench 120, which occupies a small space and is easy to place when storing. When using, there is no need to select different models of hexagon wrenches for different models of hexagon screws / bolts for carrying. Only one nested hexagon wrench needs to be carried when carrying, and there is no need to carry a number of independent hexagon wrenches, thereby improving the convenience of a number of hexagon wrenches of different models in storage, use and carrying, and further improving the user experience.
