Description

Technical Field

[0001] The present invention relates to hand tools, and particularly to small multi-purpose folding hand tools.

Background Art

[0002] In the application of manual tools, with the increasing variety of work needs, users have higher expectations for the flexibility and versatility of powered manual tools. However, existing powered tools are often designed mainly for single uses, making it difficult to handle various usage scenarios, and they can only be applied to specific types of fastening parts and operation needs, lacking flexibility and adaptability.

[0003] When users need to perform various tasks or need to handle different types and sizes, they have to carry multiple dedicated manual tools suitable for each. This not only increases the burden of carrying and storing manual tools but also reduces work efficiency.

[0004] To improve the above problems of manual tools, Patent Document 1 discloses a multi-purpose powered tool. The multi-purpose powered tool has a first end, a second end, and a pivot point. The first end has a fastening part driving housing device for accommodating a driving device for fastening parts. The second end has a tool accommodating device for accommodating a functional driving device or a functional accessory. The pivot point is arranged between the first end and the second end, and the first end and the second end are structured to be rotatable relative to each other.

[0005] However, the functionality in the aforementioned patent is limited to the point that different tool heads can be mounted at both ends, and the operational functionality is relatively simple, so it is difficult to fully meet the multi-purpose work needs of users.

Therefore, the directional terms used are not for limiting the present invention, but for exemplifying and understanding the present invention. Make this clear in advance.

[0014] As shown in FIGS. 1 to 10, the small folding hand tool according to the present invention has a pen-shaped outer shape and has the use effect of being lightweight and convenient to carry. The small folding hand tool has a pen-shaped outer shape and has the use effects of being lightweight and convenient to carry.

[0015] The small folding hand tool has a short rod 10, a connecting portion 11, a first connecting portion 12, a long rod 20, and a driving portion 21.

[0016] The short rod 10 has a connecting portion 11 along a first axis L1 and a first connecting portion 12 installed on the opposite side thereof. On the end face of the connecting portion 11, a first tool hole 111 is recessed, the horizontal cross-sectional shape of the first tool hole 111 is hexagonal, and the hole diameter of the first tool hole 111 is 1 / 4 inch. The first tool hole 111 can mount a 1 / 4-inch tool head 1. As shown in FIGS. 5 and 8, the working end of the tool head 1 can correspond to various shapes such as plus (cross-shaped), hexagonal, double hexagonal (dodecagonal), minus (flat-shaped), star-shaped, pozidrive (rice-shaped), pentagonal hollow, hexagonal hollow, ball-point hexagonal, snake eye, square (square head), triwing (three-wing), spanner bit (ten thousand characters), etc. The present invention does not limit the shape of the working end of the tool head 1.

[0017] On the outer peripheral edge of the connecting portion 11, a plurality of first arc-shaped grooves 112 are continuously recessed in an annular shape along the first axis L1 (see FIGS. 1 and 2). A first storage groove 113 is recessed in the first tool hole 111 along the first axis L1, and a first magnet component 114 is fitted and installed in the first storage groove 113. The first magnet component 114 is fitted and installed in the first storage groove 113 (see FIGS. 3 and 5). When the tool head 1 is connected to the first tool hole 111, the first magnet component 114 can adsorb the tool head 1 and achieve a rapid assembly effect.

[0018] The first connecting portion 12 has two stopper surfaces 121, which are planar and parallel to the first axis L1, and the first connecting portion 12 penetrates the two stopper surfaces 121 and has a first pivot hole 122. The edge of the first connecting section 12 is arc-shaped, and multiple positioning grooves 123 are installed in a recessed manner. In the embodiment of the present invention, there are three positioning grooves 123, and the positioning grooves 123 are spaced 90 degrees apart from each other (see Figures 2 and 3).

[0019] The long rod 20 has a drive unit 21 along the second axis L2 and a second connecting unit 22 installed on the opposite side. An intermediate section 23 is installed between the drive unit 21 and the second connecting section 22. Multiple second arc-shaped grooves 231 are continuously recessed in an annular pattern along the second axis L2 on the outer periphery of the intermediate section 23 (see Figures 1 to 3). The length of the short rod 10 is less than or equal to half the length of the long rod 20.

[0020] A second tool hole 211 is recessed into the end face of the drive unit 21, and the horizontal cross-sectional shape of the second tool hole 211 is hexagonal. The diameter of the second tool hole 211 is 4 mm, and a driver head 2 with a size of 4 mm can be connected to the second tool hole 211 (see Figures 7 and 9). The working end of the driver head 2 can accommodate various types of heads, including Phillips (cross-shaped), hexagonal (internal hexagonal), slotted (single-pronged), and Torx® (plum blossom-shaped), but the present invention does not limit the shape of the working end of the driver head 2.

[0021] A second storage compartment 212 is recessed within the second tool hole 211 along the second axis L2, and a second magnet component 213 is fitted into the second storage compartment 212 (see Figures 3 and 7). When the driver head 2 is connected to the second tool hole 211, the second magnetic component 213 attracts the driver head 2, enabling a quick assembly effect.

[0022] The drive unit 21 has a hexagonal connecting outer edge 214, and a wrench 3 can be connected to the connecting outer edge 214 of the drive unit 21, providing a working mode that allows for the application of large force (see Figure 8). In embodiments of the present invention, the outer diameter of the coupling peripheral edge 214 is 1 / 4 inch, and the wrench 3 is a ratchet wrench.

[0023] Furthermore, a pivot groove 221 is installed in a recessed manner in the second connecting portion 22 of the long rod 20, and the pivot groove 221 has two inner surfaces 222. The inner surfaces 222 of the two tanks are planar and parallel to the second axis L2. The second connecting section 22 penetrates the inner surfaces 222 of the two tanks and has a second pivot hole 223 installed within it. When the first connecting portion 12 of the short rod 10 is installed in the pivot groove 221, the two stopper surfaces 121 and the two inner surfaces 222 of the grooves face each other, and a pivot pin 30 is installed through the first pivot hole 122 of the first connecting portion 12 and the second pivot hole 223 of the second connecting portion 22. The short rod 10 and the long rod 20 are pivotally connected to each other by the pivot pin 30, so that the long rod 20 and the short rod 10 rotate relative to each other and are switched between the first working position (Figure 3) and the second working position (Figure 4).

[0024] Furthermore, a positioning component 40 is installed between the first connecting portion 12 of the short rod 10 and the second connecting portion 22 of the long rod 20, thereby positioning the short rod 10 and the long rod 20 at a high torque working angle. As shown in Figures 2 to 4, a third storage tank 224 is installed in a recessed shape within the pivot tank 221 along the second axis L2. The positioning component 40 includes an elastic component 41 and a positioning latch 42. Both ends of the elastic component 41 are connected to the bottom of the third storage tank 224 and the positioning latch 42, respectively. The elastic component 41 pushes up the positioning latch 42 and fixes it in one of the positioning grooves 123. In the embodiments of the present invention, the high-torque working angle is 90 degrees.

[0025] The add-on part 50 is detachably connected to the first tool hole 111 of the short rod 10 or the second tool hole 211 of the long rod 20. The add-on part 50 functions as an extension part, increasing the length of the short rod 10 or the long rod 20, thereby providing easier operation for the user. Alternatively, as shown in Figure 10, the add-on part 50 can be connected to the long rod 20 and the tool head 1 can be attached to the short rod 10, so that the small folding hand tool can be quickly rotated by gripping it with the fingers and placing the index finger on the add-on part 50, achieving the purpose and effect of rapid driving operation.

[0026] Furthermore, the additional component 50 has a main body 51 and a connecting portion 52 extending from the main body 51. The connecting section 52 is stepped and has a large-diameter section 521 and a small-diameter section 522. The large-diameter section 521 is connected between the small-diameter section 522 and the main body 51. The connecting section 52 can be housed in the first tool hole 111 (see Figure 7), and the small-diameter section 522 can be housed in the second tool hole 211 (see Figure 5). The length of the first tool hole 111 along the first axis L1 is equal to the length of the connecting portion 52. The length of the second tool hole 211 along the second axis L2 is equal to the length of the small diameter section 522. When the connecting portion 52 is housed in the first tool hole 111, the small diameter section 522 is attracted to the first magnet component 144. When the small diameter section 522 is housed in the second tool hole 211, the large diameter section 521 is exposed in the second tool hole 211, and the small diameter section 522 attracts the second magnet component 213.

[0027] Corresponding to the structural description in the embodiment according to the present invention, as shown in Figure 5, when in the first working position, the first axis L1 and the second axis L2 are coaxial, a 1 / 4 inch size tool head 1 is connected to the first tool hole 111 and attracted to the first magnet component 114, and the additional component 50 is connected to the second tool hole 211 of the long rod 20. In this way, the user can perform general drive operations or the quick rotation mode operation shown in Figure 10.

[0028] At the same time, as shown in Figures 5 and 6, the present invention allows for general drive operations to be performed without using the additional component 50 under certain usage conditions.

[0029] As shown in Figure 7, in a certain usage situation, when the present invention is in the first working position, a 4 mm sized driver head 2 is connected to the second tool hole 211 and is attracted by the second magnetic component 213, and the additional component 50 is connected to the first tool hole 111 of the short rod 10.

[0030] As shown in Figure 9, when in the second working position, the first axis L1 and the second axis L2 intersect each other, forming a high-torque working angle. Furthermore, the tool head 1 is fitted and connected to the short rod 10, and the driver head 2 is fitted and connected to the long rod 20. The length of the short rod 10 acts as a force arm, achieving high-torque rotational drive operation. Under certain operating conditions, as shown in Figure 4, the length of the long rod 20 can be used as a force arm, and high-torque rotational drive operation can be achieved in a similar manner.

[0031] In summary, the present invention can achieve the following effects. 1. The small, foldable hand tool according to the present invention can be used according to different usage requirements and achieve multi-purpose operation by selecting the first tool hole 111 of the short rod 10 or the second tool hole 211 of the long rod 20 and assembling a tool head 1 or driver head 2 of the corresponding size, and using an add-on part 50 for quick rotation operation. 2. The small folding hand tool according to the present invention allows the short rod 10 and the long rod 20 to be adjusted to a first working position or a second working position to meet the needs of different torque operation modes.
