Description

Technical Field

[0001] This invention relates to the field of LED disassembly and assembly tools, and more specifically, to a combination screwdriver. Background Technology

[0002] When maintaining an LED display screen, a screwdriver is needed to remove and install the screws on the screen. LED displays have a large number of screws, many of which are different in shape and size.

[0003] Related technologies use combination screwdrivers to assemble and disassemble screws of different shapes and sizes. These combination screwdrivers include a handle and multiple tool heads of different sizes. Users select the appropriate tool head based on the size and shape of the screw to be disassembled and attach it to the handle. However, this requires changing tool heads multiple times when assembling and disassembling multiple screws of different sizes on an LED display screen, making the operation cumbersome and reducing worker efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a combination screwdriver to solve the problem of low work efficiency when disassembling and assembling multiple screws of different sizes in related technologies.

[0005] To achieve the above objectives, the present invention provides a combined screwdriver, comprising: a first handle body; a multi-head structure including a first multi-head and a second multi-head, wherein the first multi-head is disposed at a first end of the first handle body, and the second multi-head is retractably disposed within the first multi-head, and the first multi-head and the second multi-head are anti-rotationally engaged; wherein the second multi-head has a first working position extending out of the first multi-head and a first clearance position retracted into the first multi-head.

[0006] Furthermore, the combination screwdriver also includes a second handle body, which is detachably connected to a first end or a second end of the first handle body; when the second handle body is installed at the first end of the first handle body, the second handle body compresses the second polygon head to keep the second polygon head in a first clearance position.

[0007] Furthermore, the combination screwdriver also includes a Phillips head structure. When the second handle is detachably connected to the first end of the first handle, the Phillips head structure is detachably connected to the end of the second handle away from the first handle; when the second handle is detachably connected to the second end of the first handle, the Phillips head structure extends detachably from the second end of the first handle into the first handle.

[0008] Furthermore, the crosshead structure includes a working section and a connecting section connected to each other. The end of the connecting section away from the working section is provided with a first anti-rotation part, and the first end of the second handle is provided with a second anti-rotation part. When the second end of the second handle is installed on the first end of the first handle or when the first end of the second handle is installed on the second end of the first handle, the second anti-rotation part and the first anti-rotation part engage to prevent rotation.

[0009] Furthermore, the crosshead structure also includes a threaded portion disposed on the outside of the connecting section, a first receiving hole disposed in the first handle body, and a threaded hole communicating with the first receiving hole disposed in the first handle body; when the first end of the second handle body is installed on the second end of the first handle body, the working section is located in the first receiving hole, the threaded portion engages with the threaded hole, and the first anti-rotation portion protrudes from the second end of the first handle body.

[0010] Furthermore, a third anti-rotation part is provided at the first end of the first handle body, and the third anti-rotation part is located on the outside of the first polygonal head. A fourth anti-rotation part is provided at the end of the second handle body that can be installed at the first end of the first handle body. When the second handle body is installed at the first end of the first handle body, the fourth anti-rotation part and the third anti-rotation part engage to prevent rotation.

[0011] Furthermore, the second handle body is provided with a second receiving hole capable of accommodating the polygonal head structure. A baffle is provided on the wall of the second receiving hole, which can cooperate with the second polygonal head stop to keep the second polygonal head in the first avoidance position.

[0012] Furthermore, the second polygon head is telescopically disposed within the first polygon head via the first elastic element. The first polygon head is provided with a mounting hole for mounting the second polygon head and the first elastic element. A first stop is provided at the opening of the mounting hole, and a second stop is provided at the bottom of the second polygon head to stop and cooperate with the first stop.

[0013] Furthermore, the polygonal head structure also includes a third polygonal head, which is telescopically disposed within the second polygonal head via a second elastic element. The second polygonal head and the third polygonal head are anti-rotationally engaged. The third polygonal head has a second working position extending out of the second polygonal head and a second clearance position retracted into the second polygonal head. Both the first and second elastic elements are compression springs, and the elastic coefficient of the first elastic element is greater than that of the second elastic element.

[0014] Furthermore, a first magnetic element is provided at the first end of the first handle, a second magnetic element is provided at the second end of the first handle, a third magnetic element is provided at the first end of the second handle, and a fourth magnetic element is provided at the second end of the second handle; the first magnetic element can magnetically engage with the fourth magnetic element, and the second magnetic element can magnetically engage with the third magnetic element.

[0015] According to the technical solution of this invention, the combination screwdriver includes a first handle and a multi-angle head structure. The multi-angle head structure includes a first multi-angle head and a second multi-angle head. The first multi-angle head is disposed at the first end of the first handle, and the second multi-angle head is retractably disposed within the first multi-angle head. The first multi-angle head and the second multi-angle head are anti-rotationally engaged. The second multi-angle head has a first working position extending out of the first multi-angle head and a first clearance position retracted into the first multi-angle head. When disassembling or assembling screws of different specifications, if the screw specification matches the second multi-angle head, the second multi-angle head is in the first working position extending out of the first multi-angle head. The operator holds and rotates the first handle, causing the first multi-angle head at the first end of the first handle to rotate. Due to the anti-rotational engagement between the first and second multi-angle heads, the second multi-angle head can rotate together with the first handle to disassemble or assemble screws that match the specifications of the second multi-angle head. When the screw's specification matches the first polygonal head, the second polygonal head is in a first clearance position retracted into the first polygonal head, allowing the first polygonal head to extend into the operating hole of the screw head. The operator holds and rotates the first handle, causing the first polygonal head on the first end of the first handle to rotate, thus allowing for the installation and removal of screws matching the first polygonal head's specification. This allows for the installation and removal of screws of various specifications and avoids the need for multiple tool head changes in related technologies, improving work efficiency. Therefore, the technical solution of this application effectively solves the problem of low work efficiency when installing and removing multiple screws of different specifications in related technologies.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 4As shown, the combined screwdriver of this embodiment includes a first shank body 10 and a polygonal head structure 30. The polygonal head structure 30 includes a first polygonal head 31 and a second polygonal head 32. The first polygonal head 31 is disposed at the first end of the first shank body 10, and the second polygonal head 32 is retractably disposed within the first polygonal head 31. The first polygonal head 31 and the second polygonal head 32 are anti-rotationally engaged. The second polygonal head 32 has a first working position extending out of the first polygonal head 31 and a first clearance position retracted into the first polygonal head 31.

[0034] Applying the technical solution of this embodiment, when disassembling and assembling screws of different specifications, if the screw specification matches the second polygonal head 32, the second polygonal head 32 is in a first working position extending out of the first polygonal head 31. The operator holds and rotates the first handle 10, causing the first polygonal head 31 on the first end of the first handle 10 to rotate. Due to the anti-rotation cooperation between the first polygonal head 31 and the second polygonal head 32, the second polygonal head 32 can rotate together with the first handle 10 to disassemble and assemble screws that match the specifications of the second polygonal head 32. If the screw specification matches the first polygonal head 31, the second polygonal head 32 is in a first clearance position retracted into the first polygonal head 31, allowing the first polygonal head 31 to extend into the operating hole of the screw head. The operator holds and rotates the first handle 10, causing the first polygonal head 31 on the first end of the first handle 10 to rotate, to disassemble and assemble screws that match the specifications of the first polygonal head 31. This allows for the assembly and disassembly of screws of various sizes, avoiding the need for multiple tool head replacements in related technologies and improving work efficiency. Therefore, the technical solution of this embodiment effectively solves the problem of low work efficiency when assembling and disassembling multiple screws of different sizes in related technologies.

[0035] like Figures 1 to 6 As shown, the combination screwdriver also includes a second handle 20, which is detachably connected to either the first end or the second end of the first handle 10. When the second handle 20 is installed at the first end of the first handle 10, it can cover the polygonal head structure 30, facilitating the storage of the combination screwdriver when the polygonal head structure 30 is not in use and preventing accidental injury to the operator from the unused polygonal head structure 30. When the second handle 20 is installed at the first end of the first handle 10, it compresses the second polygonal head 32, keeping it in a first clearance position. This reduces the size of the combination screwdriver when the second handle 20 is installed at the first end of the first handle 10, making it easier for the operator to carry.

[0036] like Figures 1 to 8As shown, the combination screwdriver also includes a Phillips head structure 50. When the second handle 20 is detachably connected to the first end of the first handle 10, the Phillips head structure 50 is detachably connected to the end of the second handle 20 away from the first handle 10. Thus, when the Phillips head structure 50 is needed to install or remove screws, it is connected to the end of the second handle 20 away from the first handle 10. Because the Phillips head structure 50 is connected to the first end of the first handle 10 via the second handle 20, the operator can rotate the Phillips head structure 50 when operating the first handle 10 and the second handle 20, improving the convenience of using the combination screwdriver. When the second handle 20 is detachably connected to the second end of the first handle 10, the Phillips head structure 50 is detachably extended from the second end of the first handle 10 into the first handle 10. Thus, when the Phillips head structure 50 is not needed to install or remove screws, it can be extended from the second end of the first handle 10 into the first handle 10 for easy storage. The Phillips head structure 50 expands the range of screws that the combination screwdriver can handle, improving its adaptability.

[0037] In this embodiment, when the polygonal head structure 30 and the crosshead structure 50 are not used, the second handle 20 is installed at the first end of the first handle 10, and the crosshead structure 50 is detachably inserted into the first handle 10 from the second end of the first handle 10.

[0038] like Figures 2 to 8 As shown, the crosshead structure 50 includes a working section 51 and a connecting section connected to each other. The working section 51 is designed for easy screw removal and installation. A first anti-rotation part 53 is provided at the end of the connecting section away from the working section 51, and a second anti-rotation part 21 is provided at the first end of the second handle 20. When the second end of the second handle 20 is installed at the first end of the first handle 10, and the crosshead structure 50 is connected to the first end of the second handle 20, the second anti-rotation part 21 engages with the first anti-rotation part 53 to prevent rotation. The crosshead structure 50 can engage with the first end of the second handle 20 through the first anti-rotation part 53 and the second anti-rotation part 21 to prevent rotation, allowing the operator to rotate the second handle 20 to rotate the crosshead structure 50.

[0039] When the first end of the second handle 20 is installed at the second end of the first handle 10, the second handle 20 can engage with the first handle 10 to prevent rotation through the second anti-rotation part 21 and the first anti-rotation part 53. This allows the other handle to rotate simultaneously when the operator rotates either the first handle 10 or the second handle 20, thus expanding the operator's grip area and facilitating operation. This allows the polygonal head structure 30 to rotate, further improving work efficiency. At this time, the crosshead structure 50 is detachably inserted into the first handle 10 from the second end, and the second polygonal head 32 can switch between the first working position and the first avoidance position.

[0040] It should be noted that the working section 51 of the crosshead structure can be a crosshead, a flathead, or a flower-shaped head. In this embodiment, when the second shank 20 is installed at the second end of the first shank 10, the end of the second shank 20 connected to the first shank 10 is the first end of the second shank 20, and the end of the second shank 20 away from the first shank 10 is the second end of the second shank 20.

[0041] In this embodiment, separating the first handle body 10 and the second handle body 20 allows the combination screwdriver to be split into two screwdrivers. One screwdriver includes the first handle body 10 and a polygonal head structure 30 disposed at the first end of the first handle body 10. The other screwdriver includes the second handle body 20 and a Phillips head structure 50 connected to the first end of the second handle body 20. This provides multiple combination options to adapt to different screw disassembly and assembly needs, further improving work efficiency.

[0042] like Figures 2 to 8 As shown, the crosshead structure 50 also includes a threaded portion 52 disposed on the outside of the connecting section. A first receiving hole 11 is provided inside the first handle 10, and a threaded hole 12 communicating with the first receiving hole 11 is also provided inside the first handle 10. When the first end of the second handle 20 is installed at the second end of the first handle 10, the crosshead structure 50 is detachably extended from the second end of the first handle 10 into the first handle 10. The working section 51 is located within the first receiving hole 11, the threaded portion 52 engages with the threaded hole 12, and the first anti-rotation portion 53 protrudes from the second end of the first handle 10. The first receiving hole 11 is provided to accommodate the working section 51 when the first end of the second handle 20 is installed at the second end of the first handle 10. The threaded portion 52 and the threaded hole 12 facilitate the detachable connection between the crosshead structure 50 and the first handle 10. The first anti-rotation part 53 protrudes from the second end of the first handle 10 so that the first anti-rotation part 53 can engage with the second anti-rotation part 21 on the second handle 20 to prevent rotation.

[0043] In this embodiment, the second end of the second handle 20 is provided with operating holes penetrating the oppositely arranged side walls of the second handle 20. The operating holes facilitate the insertion of a rod-shaped tool into the operating holes to rotate the second handle 20, thus facilitating the application of force. Because the second anti-rotation part 21 of the second handle 20 engages with the first anti-rotation part 53, rotating the second handle 20 with the rod-shaped tool causes the crosshead structure 50 to rotate as well, facilitating the connection and disconnection of the threaded part 52 on the crosshead structure 50 and the threaded hole 12 on the first handle 10.

[0044] like Figures 1 to 8As shown, a third anti-rotation part 13 is provided at the first end of the first handle 10. The third anti-rotation part 13 is located on the outside of the first polygonal head 31 to facilitate the machining of the third anti-rotation part 13 and to make the structure of the combination screwdriver more compact. A fourth anti-rotation part 22 is provided at the end of the second handle 20 that can be mounted on the first end of the first handle 10. When the second handle 20 is mounted on the first end of the first handle 10, the fourth anti-rotation part 22 and the third anti-rotation part 13 engage in anti-rotation cooperation, so that the second handle 20 can engage with the first handle 10 through the fourth anti-rotation part 22 and the third anti-rotation part 13, so that when the operator rotates one of the first handle 10 and the second handle 20, the other can rotate together, thereby expanding the operator's grip area, facilitating operation, and further improving work efficiency.

[0045] like Figures 1 to 8 As shown, the second handle 20 has a second receiving hole 23 capable of accommodating the polygonal head structure 30. The second receiving hole 23 allows the second handle 20 to be installed at the first end of the first handle 10, making the combination screwdriver structure more compact. A baffle 24 is provided on the wall of the second receiving hole 23, which can cooperate with the second polygonal head 32 to keep it in a first clearance position. This also reduces the size of the combination screwdriver when the second handle 20 is installed at the first end of the first handle 10, making it easier for the operator to carry. The baffle 24 has a simple structure and is easy to manufacture.

[0046] In this embodiment, the third anti-rotation part 13 is a polygonal prism cylinder, and the fourth anti-rotation part 22 is a polygonal hole disposed in the second receiving hole 23. The shape of the polygonal hole is adapted to the shape of the third anti-rotation part 13.

[0047] like Figures 1 to 8As shown, the second polygonal head 32 is retractably disposed within the first polygonal head 31 via the first elastic member 41. The first elastic member 41 facilitates the switching of the second polygonal head 32 between the first clearance position and the first working position, making operation convenient and improving work efficiency. When the first polygonal head 31 is needed to disassemble or assemble a screw, the second polygonal head 32 abuts against the bottom wall of the operating hole of the screw head, and the first elastic member 41 is compressed, so that the second polygonal head 32 is in the first clearance position retracted into the first polygonal head 31, allowing the first polygonal head 31 to extend into the operating hole of the screw head for disassembly or assembly. When the first polygonal head 31 is removed from the operating hole of the screw head, the first elastic member 41 springs back, causing the second polygonal head 32 to switch from the first clearance position to the first working position extended out of the first polygonal head 31. The first polygonal head 31 has a mounting hole 34 for installing the second polygonal head 32 and the first elastic member 41. The mounting hole 34 makes the installation of the second polygonal head 32 and the first elastic member 41 more convenient and quick. A first stop 35 is provided at the opening of the mounting hole 34, and a second stop 36 is provided at the bottom of the second polygonal head 32 to stop and cooperate with the first stop 35. The first stop 35 and the second stop 36 can limit the displacement between the second polygonal head 32 and the first polygonal head 31, preventing the second polygonal head 32 from coming out of the first polygonal head 31, making the extension and retraction of the second polygonal head 32 within the first polygonal head 31 more reliable.

[0048] In this embodiment, a clearance groove communicating with the opening of the mounting hole 34 is provided on the side wall of the mounting hole 34, and a first stop 35 is disposed at the opening of the clearance groove communicating with the opening of the mounting hole 34. The second stop 36 on the second polygon head 32 is placed into the first polygon head 31 along the clearance groove, and then the first stop 35 is welded to the opening of the mounting hole 34 to prevent the second polygon head 32 from coming out of the first polygon head 31.

[0049] like Figures 1 to 8As shown, the polygonal head structure 30 also includes a third polygonal head 33. The third polygonal head 33 is telescopically disposed within the second polygonal head 32 via a second elastic member 42. The second polygonal head 32 and the third polygonal head 33 are anti-rotationally engaged. The third polygonal head 33 has a second working position extending out of the second polygonal head 32 and a second clearance position retracted into the second polygonal head 32. When the third polygonal head 33 is needed to install or remove screws, it is in the second working position extending out of the second polygonal head 32. The operator holds and rotates the first handle 10, causing the first polygonal head 31 and the second polygonal head 32 on the first end of the first handle 10 to rotate. Due to the anti-rotational engagement between the second polygonal head 32 and the third polygonal head 33, the third polygonal head 33 can rotate together with the first handle 10 to install or remove screws that match the specifications of the third polygonal head 33. When the second polygonal head 32 is needed to install or remove screws, the third polygonal head 33 is in a second clearance position retracted into the second polygonal head 32, so that the second polygonal head 32 can be inserted into the operating hole of the screw head. The operator holds and rotates the first handle 10 to rotate the second polygonal head 32 on the first end of the first handle 10 to install or remove screws that match the specifications of the second polygonal head 32.

[0050] Furthermore, the third polygonal head 33 is retractably disposed within the second polygonal head 32 via the second elastic element 42. The placement of the second elastic element 42 facilitates the switching of the third polygonal head 33 between the second avoidance position and the second working position, making operation convenient and improving work efficiency.

[0051] In this embodiment, the second polygonal head 32 has a third stop, and the third polygonal head 33 has a fourth stop. The mating relationship between the third and fourth stopes is the same as the mating relationship between the first stop 35 and the second stop 36. The first polygonal head 31, the second polygonal head 32, and the third polygonal head 33 are all hexagonal heads.

[0052] In an embodiment not shown in the figure, the first polygonal head, the second polygonal head, and the third polygonal head are pentagonal heads, quadrilateral heads, or triangular heads.

[0053] like Figures 1 to 8As shown, both the first elastic element 41 and the second elastic element 42 are compression springs. These compression springs apply a force away from the first end of the first shank to the second polygonal head 32 and the third polygonal head 33, so that the second polygonal head 32 can remain in the first working position when no external force is applied, and the third polygonal head 33 can remain in the second working position when no external force is applied. When the second polygonal head 32 is used to install or remove a screw, the third polygonal head 33 abuts against the bottom wall of the operating hole of the screw head. The elastic coefficient of the first elastic element 41 is greater than that of the second elastic element 42, so that when the second polygonal head 32 and the third polygonal head 33 are subjected to the same abutting force, the deformation of the first elastic element 41 is less than that of the second elastic element 42. In this way, when the third polygonal head 33 abuts against the bottom wall of the operating hole of the screw head, the third polygonal head 33 first retracts into the second polygonal head 32, so that at least part of the second polygonal head 32 can extend out of the first polygonal head 31 under the abutment force, so that the second polygonal head 32 can be held in the first working position under the abutment force.

[0054] In this embodiment, the second polygon head 32 is provided with a third receiving hole for accommodating the first elastic member 41 and a fourth receiving hole for accommodating the second elastic member 42. The second polygon head 32 is also provided with a partition separating the third receiving hole and the fourth receiving hole.

[0055] like Figures 1 to 8 As shown, a first magnetic chuck 61 is provided at the first end of the first handle 10, and a second magnetic chuck 61 is provided at the second end of the first handle 10. A third magnetic chuck 62 is provided at the first end of the second handle 20, and a fourth magnetic chuck 62 is provided at the second end of the second handle 20. The first magnetic chuck 61 can magnetically engage with the fourth magnetic chuck, and the second magnetic chuck 61 can magnetically engage with the third magnetic chuck 62. The provision of the first magnetic chuck 61 and the fourth magnetic chuck facilitates the magnetic engagement between the first end of the first handle 10 and the second end of the second handle 20, so that when the second handle 20 is installed at the first end of the first handle 10, the first handle 10 and the second handle 20 can magnetically engage, making the structure of the combination screwdriver more reliable. The provision of the second magnetic chuck 62 facilitates the magnetic engagement between the second end of the first handle 10 and the first end of the second handle 20, so that when the second handle 20 is installed at the second end of the first handle 10, the first handle 10 and the second handle 20 can magnetically engage, making the structure of the combination screwdriver more reliable.

[0056] In this embodiment, the magnetic attraction force when the first magnetic member 61 and the fourth magnetic member are magnetically engaged is greater than the sum of the elastic forces of the first elastic member 41 and the second elastic member 42 when the second handle 20 compresses the second polygonal head 32. The first magnetic member 61 and the third magnetic member 62 are both magnetic rings, and the second magnetic member and the fourth magnetic member are both made of iron.

[0057] In this embodiment, the combination screwdriver includes the following combination forms:

[0058] The multi-head structure 30 has both an exposed state and a covered state:

[0059] like Figure 3 As shown, when the polygonal head structure 30 is in the exposed state, the first end of the second handle 20 is detachably mounted on the second end of the first handle 10, and the crosshead structure 50 is detachably inserted from the second end of the first handle 10 into the first receiving hole 11 of the first handle 10. When the polygonal head structure 30 is in the exposed state, the second polygonal head 32 can switch between a first working position and a first clearance position; the third polygonal head 33 can switch between a second working position and a second clearance position.

[0060] like Figure 6 as well as Figure 8 As shown, when the polygonal head structure 30 is in a covered state, the second end of the second handle 20 is detachably installed on the first end of the first handle 10, and the baffle 24 of the second handle 20 can cover the polygonal head structure 30, which is located inside the second handle 20.

[0061] The crosshead structure 50 has a third working position and a third clearance position:

[0062] like Figure 8 As shown, when the crosshead structure 50 is in the third working position, the second end of the second handle 20 is detachably mounted on the first end of the first handle 10, and the crosshead structure 50 is detachably connected to the first end of the second handle 20.

[0063] like Figure 3 as well as Figure 6 As shown, when the crosshead structure 50 is in the third clearance position, the crosshead structure 50 is detachably extended from the second end of the first handle 10 into the first handle 10, the working section 51 is located in the first receiving hole 11, the threaded part 52 is engaged with the threaded hole 12, and the first anti-rotation part 53 protrudes from the second end of the second handle 20.

[0064] The combination screwdriver has a folded storage configuration:

[0065] like Figure 6 As shown, when the combination screwdriver is in the storage state, the second end of the second handle 20 is detachably installed on the first end of the first handle 10, and the Phillips head structure 50 is detachably inserted from the second end of the first handle 10 into the first receiving hole 11 of the first handle 10.
