Description

Technical Field

[0001] This invention relates to a multifunctional screwdriver bit storage box and its application as a screwdriver, particularly an innovative storage box structure that allows screwdriver bit storage boxes to be interlocked and assembled for storage as a decorative item, or to be used with screwdriver bit extension rods to store screwdrivers of various specifications. Prior Technology

[0002] Currently, screwdriver bit storage devices on the market are mainly divided into two types: general toolbox-style storage boxes and screwdrivers that can hold multiple screwdriver bits. Among them, general toolbox-style storage boxes, such as the "Toolbox" in Taiwan Utility Model Patent No. M662992U, include a first elastic body and a second elastic body attached to the top surface of the first elastic body. The first elastic body and the second elastic body are recessed with at least one interconnected receiving space, and the first elastic body and the second elastic body are respectively a first predetermined color and a second predetermined color. The receiving space is provided for placing a tool.

[0003] However, although this type of toolbox can store more screwdriver bits and related accessories, and makes it easier to find and retrieve the items, it can only be used as a storage box and has no other functionality. In addition, the manufacturing cost of the storage box is relatively high. When there is a shortage of screwdriver bits, the user must buy a new toolbox, and there will be a lot of duplicate and infrequently used accessories, so it is not economical.

[0004] Furthermore, another type of screwdriver that can hold multiple screwdriver bits, such as Taiwan Utility Model Patent No. 342766U "Combined Screwdriver with Variable Working Length", has a connecting post on one end face of a rod base and a connecting groove of appropriate depth on the other end face. There are also several connecting blocks with the same structure as the base and with connecting posts and connecting grooves. Each of these blocks has a through hole for inserting the rod and is coaxially connected to the front or rear end of the base to form a handle, so that the working length of the rod protruding from the handle can be changed as needed. The base and each connecting block have a predetermined number of insertion holes for screwdriver bits to be inserted and stored. The outer circumference of the base and each connecting block is a regular polygon symmetrical to the outer circumference of the connecting post.

[0005] However, this type of assembled screwdriver has many problems, which are described below:

[0006] First, the handle of this conventional screwdriver consists of a base and a plurality of interlocking blocks. One end of the shaft is fixed to the base, and each interlocking block has only a circular through hole through which the shaft can pass. Therefore, only the base can fix the shaft and transmit torque; the other interlocking blocks are completely useless. However, the transparent base is made of non-metallic material, so its torque capacity is very limited. When the torque generated by the user's rotation is too large, the base is very easy to break and fall off, rendering the entire tool unusable as a screwdriver.

[0007] Secondly, since the conventional screwdriver has one end of the shaft fixed to the base, the shaft cannot be replaced. This makes it impossible for the conventional screwdriver to be used with other extension rods with various functions, such as bent extension rods and quick-release extension rods, for various extended applications.

[0008] Third, the design of the base and connecting block of the conventional screwdriver is not easy to grip, so an outer cover is needed to achieve anti-slip grip.

[0009] Fourth, the base and connecting block of this conventional screwdriver must be made of transparent material so that the screwdriver head inside can be seen.

[0010] Fifth, the screwdriver bit of the conventional screwdriver, which is located in the socket of the base and the connecting block below the first base (or connecting block), cannot be directly removed without removing the base, connecting block or outer cover above, below or outside. Moreover, the screwdriver bit inserted into the socket of the base or connecting block is very difficult to pull out and very difficult to use.

[0011] Sixth, the assembly of the base and connecting block of this conventional screwdriver is subject to directional restrictions, and the connecting posts and grooves of the base and connecting block must be non-circular to interlock without causing rotation. Since the base and connecting block must be made of relatively hard, transparent materials (glass, transparent plastic, or acrylic only), grooves and rubber rings must be used to prevent detachment during assembly. This increases manufacturing costs and makes it impractical and uneconomical.

[0012] Therefore, the inventor of this invention specifically addressed the problems and shortcomings of the front-opening storage box and screwdriver, and thus invented this invention. Summary of the Invention

[0013] The purpose of this invention is to provide a multifunctional screwdriver bit storage box that can be used as an assembly screwdriver bit storage box, for high-torque screwdrivers of various sizes and specifications, and as a decorative item. Compared with traditional screwdriver bit storage boxes and screwdrivers, the screwdriver bit storage box of this invention has lower manufacturing costs, the screwdriver bits are easier to find and handle sideways, the rotational torque of the assembled screwdriver can be adjusted and increased with the number of parts assembled, it can be used with various functional screwdriver bit extensions, has a good non-slip grip, and is more durable and aesthetically pleasing.

[0014] Furthermore, the screwdriver bit storage box of the present invention can be sold separately (in small packages) or in sets for various specifications of screwdriver bits (such as Phillips head, flathead, hexagonal, ball head, star head, etc.), making it convenient for users to purchase and replace them without causing unnecessary waste. It achieves the effects of energy saving, carbon reduction, environmental protection, and recycling, and has better practicality and economic benefits than traditional screwdriver bit storage boxes and screwdrivers.

[0015] To achieve the aforementioned objectives, the multifunctional screwdriver bit storage box of the present invention includes at least one body, which is integrally molded from a non-metallic material with elasticity and extensibility. A polygonal perforation is provided in the middle of the aforementioned body. A plurality of screwdriver bit receiving slots are provided around the periphery of the aforementioned polygonal perforation. A notch is provided on the outer side of the aforementioned screwdriver bit receiving slots. The width of the notch is smaller than the inner diameter of the aforementioned screwdriver bit receiving slots.

[0016] The multifunctional screwdriver bit storage box of the present invention has a first beveled surface at both the upper and lower ends of the aforementioned polygonal perforation to guide the screwdriver bit connector into the aforementioned polygonal perforation; a second beveled surface at the upper end of the aforementioned screwdriver bit receiving groove to guide the screwdriver bit into the aforementioned screwdriver bit receiving groove; and a third beveled surface at the upper position of the outer side of the aforementioned body to facilitate the user to directly remove the aforementioned screwdriver bit from the side with their fingers.

[0017] The multifunctional screwdriver bit storage box of the present invention includes a stop portion provided below the aforementioned notch to protect the screwdriver bit in the aforementioned screwdriver bit receiving slot; a plurality of grooves are provided on the outer side of the aforementioned body between adjacent notches to improve the elasticity and extensibility of the sides of the aforementioned notch; the aforementioned notch, the third beveled surface, the stop portion, the grooves and the screwdriver bit can form a significantly uneven non-slip surface on the outer periphery of the aforementioned body, and can be used to improve the grip of the aforementioned body.

[0018] This invention relates to a multifunctional screwdriver bit storage box. When the polygonal perforations of the aforementioned main body are hexagonal and the number of screwdriver bit receiving slots is odd (seven being the optimal configuration), simply rotating the two main bodies 180° apart and stacking them in opposite directions allows them to form a tightly enveloping handle. Furthermore, this invention allows at least one of the aforementioned main bodies to be connected in series with a screwdriver bit extension rod to create screwdrivers of various sizes and specifications. The rotational torque of the screwdriver is proportionally increased depending on the number of the aforementioned main bodies.

[0019] The screwdriver of this invention comprises at least one screwdriver bit storage box and one screwdriver bit extension rod. The screwdriver bit storage box is a main body, with a polygonal through hole in the center. A plurality of screwdriver bit receiving slots are arranged around the periphery of the polygonal through hole. The screwdriver bit extension rod passes through the polygonal through hole of the main body. It is particularly important to emphasize that the screwdriver bit extension rod can directly use screwdriver bit extension rods attached to various power tools or manual screw-locking tools, allowing for the recycling of these screwdriver bit extension rods.

[0021] To further understand the present invention, the optimal embodiment of the multifunctional screwdriver bit storage box is shown in Figures 1-15, and includes at least:

[0022] A body 1 is preferably integrally molded from a non-metallic material with elasticity and ductility, such as rubber or plastic. A polygonal through-hole 11 is provided in the middle of the body 1, the polygonal through-hole 11 being designed to accommodate various screwdriver bit extensions 2 (e.g., hexagonal quick-connect extensions). First beveled surfaces 111 are provided at the upper and lower ends of the polygonal through-hole 11 to guide the screwdriver bit extension 2 into the polygonal through-hole 11. A plurality of protrusions 112 are provided on the inner sidewall of the body 1 at the location of the polygonal through-hole 11. These protrusions 112 abut against and elastically support the screwdriver bit extension 2, allowing the screwdriver bit extension 2 to be securely positioned within the polygonal through-hole 11, and also facilitating the user's removal of the screwdriver bit extension 2.

[0023] The aforementioned screwdriver bit extension 2 can use accessories included with commercially available power tools, hand tools, or separately sold universal accessories. This allows the extension 2 to be used not only with the original tools but also with the storage box of this invention as a (manual) screwdriver. Furthermore, the various screwdriver bits stored in the storage box of this invention can also be used with the original power tools or (manual) screwdrivers, thus broadening the range of screw holes that various screw-locking tools can utilize.

[0024] The aforementioned body 1 has a plurality of screwdriver bit receiving slots 12 arranged around the periphery of the aforementioned polygonal through hole 11. The screwdriver bit receiving slots 12 are designed to accommodate the shapes of various screwdriver bits 3 (such as Phillips head, flathead, hexagonal head, ball head, star head, and other specifications of screwdriver bits), and can accommodate screwdriver bits of various lengths (as shown in Figure 15). The aforementioned screwdriver bit receiving slots 12 may be through-hole structures, depending on the usage requirements and the screwdriver bits to be accommodated. The upper end of the aforementioned screwdriver bit receiving slots 12 may be provided with a second beveled surface 121 to guide the aforementioned screwdriver bit 3 into the aforementioned screwdriver bit receiving slots 12.

[0025] A notch 122 is provided on the outer side of the aforementioned screwdriver bit receiving groove 12. The width of the notch 122 is smaller than the inner diameter of the aforementioned screwdriver bit receiving groove 12. This can prevent the aforementioned screwdriver bit 3 from coming out of the aforementioned screwdriver bit receiving groove 12. By utilizing the elasticity and extensibility of the aforementioned body 1, the screwdriver bit 3 placed in the aforementioned screwdriver bit receiving groove 12 can be removed by external force or pushed back into its original position, making it more convenient to pick up and put in the aforementioned screwdriver bit 3, and making it easier to find the required screwdriver bit. Furthermore, the notch 122 can be used to form a significantly textured non-slip surface on the outer side of the aforementioned body 1, making it convenient for users to hold and prevent slipping.

[0026] A stop 123 is provided below the aforementioned notch 122. The stop 123 can further protect the screwdriver bit 3 in the aforementioned screwdriver bit receiving groove 12, so that the screwdriver bit 3 can be prevented from coming out of the notch 122 when the body 1 is hit or impacted. The stop 123 can also be used to improve the grip of the aforementioned body 1, so as to form a non-slip surface with obvious concave and convex features with the aforementioned notch 122.

[0027] A third beveled surface 13 is provided on the upper outer side of the aforementioned body 1. This third beveled surface 13 is designed to work with the aforementioned screwdriver bit 3, making it convenient for the user to directly remove the aforementioned screwdriver bit 3 from the side with their fingers.

[0028] On the outer side of the aforementioned body 1, a plurality of grooves 14 are provided between adjacent notches 122. The grooves 14 are used to improve the elasticity and extensibility of the positions on both sides of the aforementioned notches 122, so that the aforementioned screwdriver bit 3 can be more easily removed from the inside of the aforementioned screwdriver bit receiving groove 12. The grooves 14 can also be used to improve the grip of the aforementioned body 1, so as to form a non-slip surface with significant concavity and convexity with the aforementioned notches 122.

[0029] As shown in Figures 3 and 4, it is particularly important to emphasize that when the polygonal perforations 11 of the aforementioned body 1 are hexagonal (i.e., the shape of a universal hexagonal quick-connect rod) and the aforementioned screwdriver bit receiving slots 12 are provided in an odd number (seven being the optimal configuration), as long as the two aforementioned bodies 1 are rotated 180° relative to each other and staggered, the screwdriver bit receiving slots 12 of each body 1 can be correspondingly positioned between two adjacent screwdriver bit receiving slots 12 of the other body 1, and the polygonal perforations 11 of the two bodies 1 are interconnected without any misalignment. Therefore, as shown in Figures 9-14, as long as the aforementioned two bodies 1 are rotated 180° relative to each other and stacked in opposite directions, the two bodies 1 can form a tightly enveloping grip.

[0030] As shown in Figures 7-13, by inserting various screwdriver tip connectors 2 into at least one of the polygonal through holes 11 of the aforementioned body 1, screwdrivers of various sizes and specifications can be formed. Each screwdriver tip connector 2 connected to one of the aforementioned body 1 can correspondingly increase the torque of the overall screwdriver, allowing the screwdriver to be directly adjusted to various sizes and specifications according to the needs of screw fastening, depending on the usage requirements.

[0031] As shown in Figure 14, the multifunctional screwdriver bit storage box of this invention can be sold separately (in small packages) or in sets for various specifications of screwdriver bits (such as Phillips head, flathead, hexagonal, ball head, star head, etc.), making it convenient for users to purchase and replace them without causing unnecessary waste. It can also be used as a decoration, achieving the effects of energy saving, carbon reduction, environmental protection, and recycling. Compared with traditional screwdriver bit storage boxes and screwdrivers, it has better practicality and economic benefits, which is the basis of this invention.
