Description
Technical Field
[0001] This utility model relates to the field of disassembly and assembly tools, and in particular to a screw tool. Background Technology
[0002] When installing mechanical structures, it is often necessary to use some installation tools, such as screwdrivers. Screwdrivers can be used to install and remove bolts, screws and other connectors. Commonly used screwdrivers include Phillips head screwdrivers, flathead screwdrivers, and Allen wrenches.
[0003] In existing technology, hex wrenches are typically L-shaped. When using a hex wrench to install or remove hex bolts, the bent end is inserted into the hex socket, and the hand is held on the straight end to tighten. Furthermore, the handle of such hex wrenches is usually also hexagonal. Using this type of wrench puts considerable pressure on the worker's hand, which can easily lead to hand injuries with prolonged use and is uncomfortable. In addition, the straight end is relatively short, making it inconvenient for the worker to grip, and the torque generated during tightening is small, often requiring considerable force to tighten the bolts, which is time-consuming and laborious. Moreover, each type of screwdriver is usually only suitable for removing one type of bolt, requiring workers to carry multiple types of screwdrivers, which is inconvenient to store and costly. Utility Model Content
[0004] The purpose of this utility model is to provide a screw tool that saves time and effort, avoids putting excessive pressure on the worker's hands, prevents hand injuries, provides good comfort, has strong versatility, and can reduce the cost of disassembly work.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A screwdriver is provided, comprising:
[0007] The gripping part has at least one through hole along its thickness direction;
[0008] The device includes at least one internal hexagon plug, which is inserted through the through hole and can move along the thickness direction of the gripping part, so that the working end of the internal hexagon plug protrudes from the outer surface of the gripping part or is retracted into the through hole.
[0009] A screwdriver bit is inserted into one end of the grip portion along its length.
[0010] Optionally, the internal hexagon plug includes a through section and a working end connected together. The through section passes through the through hole, and an abutment boss is provided on the side of the through section opposite to the working end. The cross-sectional area of the abutment boss is larger than the cross-sectional area of the through hole.
[0011] Optionally, the gripping part is provided with a receiving groove, the receiving groove being located on the side of the gripping part opposite to the working end of the internal hexagon plug, and the through hole is provided in the receiving groove.
[0012] Optionally, when the working end of the internal hexagon plug is retracted into the through hole, the upper surface of the abutment boss of the internal hexagon plug is lower than or level with the upper surface of the gripping part.
[0013] Optionally, the screw tool further includes a protective element, which is embedded in the receiving groove and fastened to the internal hexagon plug.
[0014] Optionally, the protective element includes a rubber protective plug.
[0015] Optionally, the screw tool is provided with a plurality of hexagon socket inserts, the gripping part is provided with a plurality of through holes spaced apart, the plurality of hexagon socket inserts are inserted into the plurality of through holes in a corresponding manner, and the working ends of the plurality of hexagon socket inserts are of different sizes.

[0019] The beneficial effects of this utility model are:
[0020] This utility model provides a screwdriver, including a grip, an internal hexagonal insert, and a screwdriver bit. When it is necessary to disassemble or install an internal hexagonal bolt, the operator presses the end of the internal hexagonal insert away from the working end, causing the insert to move along the thickness direction of the grip, so that the working end protrudes from the outer surface of the grip, extending out of the through hole. The working end can then be inserted into the hexagonal hole of the internal hexagonal bolt. The operator can then hold the grip or the screwdriver bit and rotate the grip and screwdriver bit around the working end as an axis, thereby rotating the internal hexagonal bolt to achieve disassembly or installation. Alternatively, the internal hexagonal insert can be kept retracted within the through hole, allowing the screwdriver bit to disassemble bolts or screws of the corresponding type.
[0021] By providing a through hole in the grip and inserting the hex socket head cap screwdriver through it, the working end can be selectively extended or retracted into the through hole as needed. During rotation, the operator can hold either the grip or the screwdriver head; both act as the lever arm for rotating the hex socket head cap screwdriver, thus extending its lever arm.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0032] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0033] This embodiment provides a screw tool, such as Figures 1 to 3 As shown, using this screwdriver to disassemble or install bolts or screws can save time and effort, avoid putting excessive pressure on the worker's hands, prevent hand injuries, and provide good comfort. In addition, this screwdriver can be used to disassemble other types of bolts or screws, as well as hex bolts, which has strong versatility, high functionality, and is easy to store, thus reducing the cost of disassembly work.
[0034] like Figures 1 to 3 As shown, the screwdriver includes a gripping part 1, an internal hex socket insert 2, and a screwdriver bit 3. The gripping part 1 has at least one through hole 11 along its thickness direction, and the internal hex socket insert 2 has at least one through hole. The internal hex socket insert 2 is disposed through the through hole 11 and is movable along the thickness direction of the gripping part 1, so that the working end 22 of the internal hex socket insert 2 protrudes from the outer surface of the gripping part 1 or is retracted into the through hole 11. The screwdriver bit 3 is inserted into one end of the gripping part 1 along its length direction.
[0035] When it is necessary to remove or install a hex socket head cap screw, the operator presses the end of the hex socket insert 2 away from the working end 22, causing the hex socket insert 2 to move along the thickness direction of the grip 1. This causes the working end 22 to protrude from the outer surface of the grip 1, extending out of the through hole 11. At this point, the working end 22 can be inserted into the hexagonal hole of the hex socket head cap screw. Then, the operator can hold the grip 1 or the screwdriver head 3 and rotate the grip 1 and the screwdriver head 3 around the working end 22 as an axis, thereby rotating the hex socket head cap screw to remove or install it. Alternatively, the hex socket insert 2 can be kept retracted in the through hole 11, and the screwdriver head 3 can be used to remove the corresponding type of bolt or screw.
[0036] By providing a through hole 11 on the grip 1 and inserting the hex socket head cap screwdriver 2 through the through hole 11, the working end 22 can be selectively extended out of or stored in the through hole 11 as needed. During rotation, the operator can hold either the grip 1 or the screwdriver head 3. Both the grip 1 and the screwdriver head 3 act as the rotation lever arm for the hex socket head cap screwdriver 2, thus lengthening the lever arm. This allows the operator to use the hex wrench function of the screwdriver tool, saving time and effort while avoiding excessive pressure on the operator's hands, preventing hand injuries, and providing good comfort. Furthermore, this screwdriver tool can be used to disassemble other types of bolts or screws, as well as hex socket head cap screws, exhibiting strong versatility, high functionality, and easy storage, reducing the cost of disassembly work.
[0037] Optionally, such as Figures 1 to 3 As shown, the screwdriver has multiple hexagon socket inserts 2, and the gripping part 1 has multiple through holes 11 spaced apart along its extension direction. The multiple hexagon socket inserts 2 are inserted one-to-one into the multiple through holes 11, and the cross-sectional areas of the working ends 22 of the multiple hexagon socket inserts 2 are different from each other. By providing multiple through holes 11, multiple hexagon socket inserts 2 can be inserted, and the different cross-sectional areas of the working ends 22 of the multiple hexagon socket inserts 2, i.e., different sizes of the working ends 22, allow the gripping part 1 to simultaneously accommodate multiple hexagon socket inserts 2 of different sizes. The working end 22 of the corresponding size can be flexibly selected according to the size of the hexagonal hole of the bolt being installed in actual working conditions, making the screwdriver highly versatile.
[0038] In this embodiment, two hexagon socket plugs 2 are provided, and the cross-sectional areas of the working ends 22 of the two hexagon socket plugs 2 are different. In other embodiments, other numbers of hexagon socket plugs 2 can be provided according to actual needs, and the cross-sectional areas of the working ends 22 of any two hexagon socket plugs 2 are different.
[0039] It should be noted that the inner diameters of the multiple through holes 11 are different from each other, and the inner diameter of each through hole 11 is the same as the outer diameter of the working end 22 inserted into the through hole 11.
[0040] Optionally, such as Figures 1 to 3 As shown, the hex socket head cap insert 2 includes a through section 21 and a working end 22 connected together. The through section 21 passes through the through hole 11, and an abutment boss 23 is provided on the side of the through section 21 opposite to the working end 22. The cross-sectional area of the abutment boss 23 is larger than the cross-sectional area of the through hole 11. When using the hex socket head cap insert 2 to remove or install bolts, the operator can press the abutment boss 23, causing the hex socket head cap insert 2 to move along the thickness direction of the gripping part 1 until the abutment boss 23 abuts against the gripping part 1. At this time, the working end 22 extends out of the through hole 11, while the through section 21 remains inserted in the through hole 11. By providing the abutment boss 23, the separation of the hex socket head cap insert 2 from the gripping part 1 can be prevented, ensuring the normal use of the screwdriver.
[0041] like Figures 1 to 3 As shown, the gripping part 1 is provided with a receiving groove 12. The receiving groove 12 is located on the side of the gripping part 1 opposite to the working end 22 of the internal hexagon plug 2, and the through hole 11 is provided in the receiving groove 12. By providing the receiving groove 12, the thickness of the gripping part 1 can be reduced, which is beneficial for pressing the working end 22 of the internal hexagon plug 2 out of the through hole 11, ensuring that the working end 22 has sufficient extension length in the working state.
[0042] It should be noted that when the working end 22 of the hex socket plug 2 is retracted into the through hole 11, the upper surface of the abutment boss 23 of the hex socket plug 2 is lower than or level with the upper surface of the gripping part. This can prevent the upper end of the hex socket plug 2 from protruding and scratching the staff, thus ensuring safety.
[0043] Optionally, the screwdriver also includes a protective element. The protective element is embedded in the receiving groove 12 and fastened to the hex socket plug 2. By providing the protective element, the through section 21 and the abutment boss 23 of the hex socket plug 2 can be covered, which can prevent the accumulation of debris in the receiving groove 12 due to exposure, and also prevent other items from being hooked due to the exposure of the through section 21 and the abutment boss 23, thus further improving safety.
[0044] For example, the protective element includes a rubber protective plug.
[0045] Optionally, limiting structures are provided on both the inner wall of the through hole 11 and the outer wall of the through section 21. When the working end 22 protrudes from the outer surface of the gripping part 1, the limiting structures on the inner wall of the through hole 11 and the outer wall of the through section 21 cooperate to fix the internal hexagon plug 2 inside the through hole 11. By providing limiting structures on the inner wall of the through hole 11 and the outer wall of the through section 21, the through section 21 can be clamped, thereby positioning the working end 22 axially and preventing the working end 22 from moving axially, thus controlling the extension length of the working end 22.
[0046] In this embodiment, a limiting protrusion is provided on the inner wall of the through hole 11, and a limiting groove is recessed at the upper end of the through section 21. When the working end 22 protrudes from the outer surface of the gripping part 1, the limiting protrusion is engaged in the limiting groove.
[0047] It should be noted that both the inner wall of the limiting groove and the outer wall of the limiting protrusion are set to be arc-shaped to avoid stress concentration, and the arc-shaped transition connection facilitates the insertion and removal of the limiting protrusion.
[0048] Optionally, the side wall of the grip 1 is provided with an anti-slip structure. By providing an anti-slip structure, the friction and contact area between the worker's hand and the grip 1 can be increased, the gripping force can be enhanced, and the worker can be prevented from being unable to tighten the bolt due to hand slippage. Moreover, when it is necessary to tighten the bolt, the anti-slip structure can convert most of the force applied by the worker into the torque of rotating the bolt, which is beneficial to saving time and effort.
[0049] For example, the anti-slip structure includes a plurality of evenly distributed circular protrusions. In other embodiments, the anti-slip structure may also be configured as protrusions or textures of other shapes, which are not limited herein.
[0050] Optionally, such as Figure 1 and Figure 2 As shown, the cross-sectional shape of the insertion end of the screwdriver bit 3 is different from the cross-sectional shape of the working end 22 of the internal hex socket 2. By setting the cross-sectional shape of the insertion end of the screwdriver bit 3 to other shapes, the screw tool can be inserted into the holes of various bolts, thereby giving the screw tool strong versatility and functionality.
[0051] For example, the cross-sectional shape of the connector may include a cross shape or a straight line shape.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
