Description

Technical Field

[0001] This utility model relates to the field of manual tool technology, and in particular to a modular manual tool. Background Technology

[0002] Screwdrivers and hex wrenches are common mechanical fastening tools. They are used by attaching them to the inside of screws or bolts and rotating them to install or remove them. Current screwdrivers and hex wrenches typically consist of a single shaft with a fixed or detachable cutting head. When the shaft and cutting head are detachable, carrying the screwdriver or hex wrench requires carrying the shaft and cutting head separately, which is inconvenient and the cutting head is easily lost.

[0003] The related technology discloses a modular screwdriver, which consists of a set of small screwdrivers connected together. Each small screwdriver includes a blade and a handle. The blade is fixedly connected to the front end of the fixed part of the handle. The rear end of the fixed part is hollow and is fixedly connected to an outer shell. The front and rear ends of the fixed part and the outer shell are respectively stepped. Adjacent small screwdrivers are inserted and fixed, making them easy to use and store.

[0004] However, the aforementioned connectable screwdrivers can only be connected end to end in one direction, resulting in a fixed connection shape. The diameter of the connected handle is relatively small, making it difficult for workers to grip the handle securely and prone to slipping. This makes it difficult to apply force effectively when tightening high-resistance screws or bolts, reducing work efficiency and greatly increasing the labor intensity and fatigue of workers. In some cases, improper force application may even cause the tool to slip off, posing a safety risk. Utility Model Content

[0005] The purpose of this utility model is to provide a modular hand tool to solve the technical problems of existing modular screwdrivers, such as limited modularity, small contact area between the palm and the handle, difficulty in gripping securely, and easy slippage.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 8As shown, this utility model provides a modular hand tool, including multiple first splicing units 1 and multiple second splicing units 2. Each first splicing unit 1 includes a base 11 and a blade 12 connected along a first direction (X direction in the figure). The base 11 has a receiving groove 111 with an opening facing away from the blade 12 along the first direction. One end of the blade 12 of one first splicing unit 1 can be detachably and anti-rotationally connected to the receiving groove 111 of another first splicing unit 1. A first splicing member is provided on one side of the base 11 along a second direction (Y direction in the figure), the second direction being perpendicular to the first direction. The second splicing unit 2 includes a base 11 and a blade 12 connected along a first direction. The base 11 has a receiving groove 111 with an opening facing away from the blade 12 along the first direction. One end of the blade 12 of one second splicing unit 2 can be detachably and anti-rotationally connected to the receiving groove 111 of another second splicing unit 2. The base 11 is provided with a second splicing component that can cooperate with the first splicing component on one side along the second direction.

[0036] In this embodiment, the first splicing component is a magnetic suction component 112, and the second splicing component is an adsorption component 113 that cooperates with the magnetic suction component.

[0037] Multiple first splicing units 1 are spliced ​​end-to-end along a first direction via one end of the cutter head 12 and one end of the receiving groove 111. Multiple second splicing units 2 are also spliced ​​end-to-end along the first direction via one end of the cutter head 12 and one end of the receiving groove 111. The first splicing units 1 and 2 are then spliced ​​along a second direction via magnetic suction 112 and suction 113. This achieves splicing freedom of the connectable hand tool along both the first and second directions, increasing the length of the connectable hand tool in the first direction and the width in the second direction. This, in turn, increases the contact area and friction between the worker's palm and the handle of the connectable hand tool, allowing for a stable grip when tightening high-resistance screws, reducing the risk of tool slippage, improving operational safety and work efficiency, and alleviating labor intensity and fatigue. The multiple first splicing units 1 and multiple second splicing units 2 are spliced ​​together to form a whole, making them easy to carry and store, and preventing the loss of scattered parts.

[0038] Optionally, the connection method between one end of the blade 12 of the first splicing unit 1 and the receiving groove 111, and the connection method between one end of the blade 12 of the second splicing unit 2 and the receiving groove 111, can be one of plug-in connection, snap-fit ​​connection, or magnetic connection. All of the above connection methods can achieve quick connection and disassembly of two adjacent first splicing units 1 or two adjacent second splicing units 2. When the connection method between one end of the blade 12 of the first splicing unit 1 and the receiving groove 111 is a snap-fit ​​connection, the structure of the first splicing unit 1 can be... Figure 8The structures shown, including the plug-in and snap-fit ​​connections, are all mature detachable connection methods in the existing technology and will not be described in detail here. It is understood that, regardless of the connection method used, relative rotation between two adjacent first splicing units 1 or two adjacent second splicing units 2 should be avoided.

[0039] Optionally, such as Figures 2-7 As shown, the base 11 includes a mounting portion 114 and a receiving portion 115 distributed along a first direction. A receiving groove 111 is formed in the receiving portion 115, and the mounting portion 114 has a mounting groove 116. The mounting groove 116 has an opening facing away from the receiving portion 115 along the first direction. The cutting head 12 is detachably anti-rotationally connected to the mounting groove 116. By dividing the base 11 into the mounting portion 114 and the receiving portion 115, the structure of each first splicing unit 1 or second splicing unit 2 is made uniform, simplifying the production and assembly process, reducing costs, and improving the versatility and interchangeability of each splicing unit.

[0040] Furthermore, such as Figure 3 and Figure 6 As shown, the mounting portion 114, along the first direction from the end closest to the cutter head 12 to the end furthest from the cutter head 12, consists of a first mounting portion and a second mounting portion. The cross-section of the first mounting portion along the second direction is circular, while the cross-section of the second mounting portion along the second direction is non-circular. The receiving groove 111, along the first direction from the end closest to the cutter head 12 to the end furthest from the cutter head 12, consists of an interconnected cutter head receiving groove, a first receiving groove, and a second receiving groove. The cutter head receiving groove is configured to receive the cutter head 12, the first receiving groove is configured to receive the first mounting portion, and the second receiving groove is configured to receive the second mounting portion. The first mounting portion, the first receiving groove, the second mounting portion, and the second receiving groove form a stepped mating structure along the first direction, enabling precise radial and circumferential positioning when two first splicing units 1 or two second splicing units 2 are spliced. The circular first mounting portion and the first mounting groove mainly bear the positioning and part of the radial force, while the non-circular second mounting portion and the second mounting groove are used to transmit torque. This structure makes the force distribution of the splicable hand tool more reasonable.

[0041] Optionally, a magnetic ring is provided in the first receiving groove, and the first mounting part is made of a ferromagnetic material that can be attracted by the magnetic ring. After the first mounting part enters the first receiving groove, the magnetic ring can magnetically attract the first mounting part, increasing the splicing stability of two adjacent first splicing units 1 or two adjacent second splicing units 2 along the first direction.

[0042] Optionally, the connection between the blade head 12 and the mounting slot 116 can be a plug-in connection, a snap-fit ​​connection, or a magnetic connection. That is, the blade head 12 and the mounting part 114 are quickly detachable, allowing operators to replace different types of blade heads 12 on a single base 11 as needed, greatly expanding the applicable scenarios for modular hand tools.

[0043] Furthermore, when the connection between the cutter head 12 and the mounting groove 116 is a plug-in or magnetic connection, the cross-section of the mounting groove 116 along the second direction is non-circular, and the cross-section of the cutter head 12 along the second direction matches the cross-section of the mounting groove 116. This structural design effectively prevents relative rotation between the cutter head 12 and the mounting groove 116. For example, the cross-sections of the mounting groove 116 and the cutter head 12 along the second direction can be hexagonal or triangular.

[0044] For example, the cutting heads 12 of the multiple first splicing units 1 or multiple second splicing units 2 are one or more of the following: flathead cutting heads, cross cutting heads, star cutting heads, hexagonal cutting heads, square cutting heads, or triangular cutting heads. By equipping various sizes and types of cutting heads 12, workers can customize the splicing order of the first splicing units 1 or the second splicing units 2 according to the type of screw or bolt, making the splicable hand tool adaptable to the needs of different scenarios and improving its practical value.

[0045] Optionally, such as Figure 4 and Figure 7 As shown, the side of the base 11 away from the magnetic member 112 or the adsorption member 113 along the second direction is provided with an arc-shaped grip portion 117. When the first splicing unit 1 and the second splicing unit 2 are spliced ​​along the second direction, the arc-shaped grip portion 117 can better fit the curvature of the palm, improving the grip comfort of the staff.

[0046] Furthermore, the outer periphery of the arc-shaped grip 117 is provided with an anti-slip pad. The anti-slip pad, such as rubber or silicone, can significantly increase the friction between the hand and the tool, allowing the operator to grip firmly even when their palms are sweaty or oily, further improving the anti-slip performance of the connectable hand tools.

[0047] In addition, this utility model also includes another embodiment, which differs from the above embodiment only in the following aspects, with the other features being the same: the first splicing component includes a snap-fit ​​component / slot, and the second splicing component is a corresponding snap-fit ​​slot / slot.

[0048] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
