Description

Technical Field

[0001] This utility model relates to the field of hardware tools technology, specifically a modular tool assembly. Background Technology

[0002] In everyday repair, assembly, and home DIY scenarios, various hand tools are essential operating equipment, such as wrenches and screwdrivers. Traditional hand tools are mostly individual units, each with a single function, and need to be stored and carried separately. This decentralized tool system has obvious drawbacks: when multiple tasks need to be completed, users need to carry multiple tools, which not only increases the burden of carrying them but also makes it easy to miss some due to the large number of tools, affecting the work progress; at the same time, scattered tools are easy to lose during storage, and collisions between them can cause wear and tear, shortening their lifespan. To improve this situation, some combination tools have appeared on the market. However, the connection structure between the tool head and handle of existing combination tools is poorly designed, often using simple sockets or snap-fit ​​connections. These connections are prone to loosening and slippage during operations with high force, leading to unstable torque transmission, affecting operational accuracy, and even posing safety hazards. Secondly, the tool head replacement process is cumbersome, requiring additional tools or complex operations, making quick disassembly and assembly impossible and reducing work efficiency. Thirdly, the storage structure is rudimentary, mostly using simple cloth bags or unpartitioned boxes for storage, which makes the tool heads prone to mutual compression and wear, and inconvenient to access, making it difficult to quickly find the required tool. Fourthly, the grip design lacks ergonomic considerations, easily leading to hand fatigue during prolonged use and affecting the operating experience. Utility Model Content

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Example 1: As Figures 1-6 ,include: The handle 100 has an arc groove 110 on its outer wall, and a threaded tube 140 is fixedly connected to the outer wall of the front end of the handle 100. The inner wall of the threaded tube 140 has an internal thread 141. The connecting rod 200 has a threaded rod 230 at its tail end, and an external screw on the outer wall of the threaded rod 230. The threaded rod 230 is threaded to the inner wall of the threaded tube 140. The connecting rod 200 has a hexagonal insertion hole 240 on the outer wall of its front end. Tool head 300, there are several tool heads 300, tool head 300 is a wrench or screwdriver.

[0018] The specific application scenario of this embodiment is as follows: The core of the combined tool assembly lies in realizing basic operating functions through the combination of handle 100, connecting rod 200 and tool head 300. Handle 100 serves as a gripping component, and its outer wall arc groove 110 conforms to the hand gripping posture, making it convenient for the user to apply force. The threaded tube 140 at the front end of handle 100 and the threaded rod 230 at the rear end of connecting rod 200 are threadedly connected through internal thread 141 and external screw. This connection method can ensure that the two are stably connected and transmit torque. The hexagonal insertion hole 240 at the front end of connecting rod 200 is used to install tool head 300. When a twisting or turning operation is required, the tool head 300 with the corresponding function is engaged with hexagonal insertion hole 240. The user grips handle 100 and applies force, which is transmitted to tool head 300 through connecting rod 200, thereby completing the operation of the workpiece and realizing the integration of multiple basic tool functions.

[0019] Example 2: Figures 1-5 Anti-slip pads 120 are fixedly installed on both sides of the handle 100. A rounded rectangular groove 130 is opened on the inner wall of the tail of the handle 100 for hanging and storage. A nut 210 is fixedly installed on the outer wall of the connecting rod 200. The nut 210 is used to connect and disconnect the connecting rod 200 and the threaded tube 140 with a wrench. A first limiting baffle 220 is fixedly connected to the outer wall of the connecting rod 200. The first limiting baffle 220 limits the outer wall of the threaded tube 140. The wrench is an adjustable wrench. The screwdrivers include a Phillips screwdriver and a flathead screwdriver. A hexagonal prism 320 is fixedly connected to the tail of the tool head 300.

[0020] The specific application scenario of this embodiment is as follows: the anti-slip pads 120 on both sides of the handle 100 increase the friction between the hand and the handle 100, preventing slippage during operation, improving grip comfort and operational safety. The rounded rectangular groove 130 at the tail of the handle 100 can be used for hanging and storage, making it convenient to store and retrieve components when they are not in use. The nut 210 on the outer wall of the connecting rod 200 makes it easy to reinforce or disassemble the connection between the connecting rod 200 and the threaded tube 140 with tools such as wrenches, ensuring a tight connection. The first limiting baffle 220 abuts against the outer wall of the threaded tube 140, limiting the depth to which the connecting rod 200 is screwed into the threaded tube 140, avoiding excessive screwing that could cause structural damage. The hexagonal prism 320 at the tail of the tool head 300 is adapted to the hexagonal insertion hole 240, ensuring that the tool head 300 does not slip when under force. At the same time, different tool heads 300, such as adjustable wrenches, Phillips screwdrivers, or flathead screwdrivers, can be replaced as needed to adapt to diverse operating scenarios.

[0021] Example 3: Figure 5 and Figure 6The hexagonal prism 320 is connected to the inner wall of the hexagonal socket 240 by insertion. The outer wall of the hexagonal prism 320 is provided with a magnetic block. The hexagonal prism 320 and the hexagonal socket 240 are magnetically detachably connected. The outer wall of the hexagonal prism 320 is fixedly installed with a second limiting piece 310, which cooperates with the end of the connecting rod 200 for limiting.

[0022] The specific application scenario of this embodiment is as follows: The connection stability and ease of assembly / disassembly between the tool head 300 and the connecting rod 200 are ensured. The hexagonal prism 320 at the tail of the tool head 300 engages with the hexagonal insertion hole 240 at the front end of the connecting rod 200. The hexagonal structure of the hexagonal prism 320 effectively transmits torque, preventing the tool head 300 from rotating relative to the connecting rod 200 during operation. The magnetic block on the outer wall of the hexagonal prism 320 attracts the inner wall of the hexagonal insertion hole 240, forming a magnetic connection, further enhancing the bonding force and preventing the tool head 300 from falling off during operation. The second limiting piece 310 abuts against the end of the connecting rod 200, limiting the installation position of the tool head 300 to ensure it is installed correctly. Simultaneously, it disperses some force when subjected to stress, protecting the connection structure. When the tool head 300 needs to be replaced, only a certain pulling force needs to be applied to overcome the magnetic attraction, allowing the tool head 300 to be pulled out of the hexagonal insertion hole 240, achieving quick assembly / disassembly.

[0023] Example 4: Figure 1 It also includes a storage box 400. The inner wall of the storage box 400 is provided with a handle compartment 410 and a tool head compartment 420. There are several tool head compartments 420. The handle compartment 410 is used to store the handle 100, and the tool head compartment 420 is used to store the tool head 300. The top of the storage box 400 is connected to the cover plate 430 by a hinge. The cover plate 430 and the storage box 400 are magnetically connected.

[0024] The specific usage scenario of this embodiment is as follows: the handle compartment 410 inside the storage box 400 is specifically used to place the handle 100, while the tool head compartment 420 is set according to the number and specifications of the tool heads 300, and is used to store each tool head 300 separately to avoid collision and wear between the parts. The cover plate 430 on the top of the storage box 400 rotates by a hinge and is magnetically connected to the storage box 400 after closing, ensuring the airtightness of the storage box 400 and preventing dust from entering or parts from falling out. When carrying or not in use, the handle 100 and all tool heads 300 are placed into their respective compartments and the cover plate 430 is closed, which can effectively protect each part of the components, extend their service life, and facilitate the overall carrying and management of the components, ensuring that all parts are complete when in use.

[0025] The working principle of this utility model is as follows: When used by those skilled in the art, the handle 100 serves as the gripping base. The threaded tube 140 at the front end of the handle 100 is threadedly connected to the threaded rod 230 at the tail end of the connecting rod 200, ensuring stable force transmission. The hexagonal insertion hole 240 at the front end of the connecting rod 200 cooperates with the hexagonal prism 320 at the tail end of the tool head 300, and the magnetic attraction enables quick disassembly and assembly and stable connection of the tool head 300, ensuring effective torque transmission. The arc groove 110 and anti-slip pad 120 on the handle 100 improve grip comfort and stability. The nut 210, the first limiting baffle 220, the second limiting piece 310 and other structures further enhance the reliability and safety of the connection. The handle compartment 410 and the tool head compartment 420 in the storage box 400 organize the various components in an orderly manner. The magnetic connection of the cover plate 430 ensures the sealing of the storage, realizing convenient carrying and protection of the components.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
