[0030] When repairing mobile phones, screwdrivers and blades of various sizes are often used (the blades are held in place using hand tools).
[0031] In existing hand tools, the screwdriver tip and blade are easily replaceable, but other parts of the hand tool are not easily or cannot be replaced. When other parts of the hand tool are damaged, the user needs to replace the entire hand tool except for the tip and blade, resulting in unnecessary waste.
[0032] To address the aforementioned issues, this patent provides a modular hand tool designed to allow for the disassembly and assembly of all its components.
[0033] For ease of understanding, the specific implementation methods of the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0034] Please see Figure 1-4A combination hand tool includes: a handle 100 having opposing first and second ends; a tool head 200 detachably mounted to the first end; and a retaining head 300 rotatable relative to the handle 100 and detachably mounted to the second end. Both the tool head 200 and the retaining head 300 are detachably mounted to the handle 100, allowing the user to replace only one of the tool head 200, the retaining head, or the handle 100 individually, without needing to replace the entire hand tool and avoiding unnecessary waste.
[0035] It should be noted that, to facilitate user gripping of the handle 100, this embodiment provides the following implementation method. Please refer to... Figure 1 or Figure 3 The combined hand tool also includes a grip portion 400 sleeved on the handle 100. The grip portion 400 is circumferentially fixed to the handle 100, meaning that the grip portion 400 cannot rotate around the handle 100. In this embodiment, the circumferential fixation of the grip portion 400 and the handle 100 is not limited. Preferably, a limiting groove can be provided on the inner side of the grip portion 400, and a limiting protrusion can be provided on the outer circumferential surface of the handle 100, with the limiting protrusion embedded in the limiting groove. The grip portion 400 and the handle 100 can slide relative to each other along the axial direction to change the relative position of the handle 100 and the grip portion 400. Thus, the user can control the distance between the grip portion 400 and the tool head 200 according to the situation, such as adjusting the distance according to the size of the hand, to facilitate the user's grip on the handle 100. In electronic equipment repair scenarios, hot air guns are often used to heat components. If the grip 400 is close to the tool head 200, the user is prone to burns. Adjusting the grip 400 to a position away from the tool head 200 can avoid this problem. Furthermore, since the grip 400 can slide relative to the handle 100, it can be detached from the handle 100. This allows the user to replace the grip 400 as needed (e.g., if the grip 400 is damaged, or if a larger or smaller grip 400 is used). When the grip 400 is made of rubber or plastic, it also prevents static electricity from being transferred from the hands to the tool head 200, thus preventing damage to the components. Based on the above implementation, there are various ways to circumferentially fix the grip 400 to the handle 100. This embodiment provides the following implementation. Please refer to... Figure 2 and Figure 4 The cross-section of the handle body 100 or its cylindrical portion perpendicular to the axial direction of the handle body 100 is non-circular. The grip portion 400 is adapted to the outer peripheral surface of the handle body 100 or its cylindrical portion. This implementation method makes the grip portion 400 circumferentially fixed to the handle body.
[0036] It should be noted that after the grip 400 slides relative to the handle 100, it needs to maintain its slid-down position. To achieve this effect, this embodiment provides the following two implementation methods. Method 1: Please refer to... Figure 2 The gripping portion 400 includes an outer layer 410 and an inner layer 420, wherein the inner layer 420 of the gripping portion 400 is made of a soft material. Method Two: Please refer to... Figure 4 The grip 400 is made of a soft material. These two methods ensure sufficient static friction between the grip 400 and the handle 100, allowing the grip 400 to maintain its slidable position. The required size of the grip 400 varies depending on the application. For example, when a larger torque is required, a larger grip 400 is needed to reduce the force required for hand-twisting, making it more effortless. The detachable and replaceable grip 400 allows the same tool to be adapted to different usage needs by replacing different grips 400.
[0037] It should be noted that, in order to prevent the user's hand from slipping when holding the grip part 400, this embodiment provides the following implementation method. Please refer to... Figure 1 or Figure 3 The outer surface of the grip part 400 is provided with anti-slip grooves 430, thereby preventing the user from slipping when gripping the grip part 400.
[0038] It should be noted that the bearing head 300 can be implemented in various ways; this embodiment provides the following implementation. Please refer to [link / reference]. Figure 1-4 The support head 300 includes a bearing 310 and an end cap 320 covering the bearing. The bearing 310 allows the user to rotate the assembled hand tool more smoothly, and the end cap 320 covering the bearing 310 can protect the bearing 310 and prevent it from being uncomfortable to the hand.
[0039] It should be noted that the bearing 310 has multiple fixing methods; this embodiment provides the following implementation method. Please refer to [link / reference]. Figure 2 or Figure 4 The second end has a screw hole, and the bearing 310 is screwed into the screw hole. This method allows the bearing 310 to be fixed to the second end with screws, or the bearing 310 to be removed by loosening the screws, achieving a detachable installation effect.
[0040] It should be noted that, in order to protect the bearing 310 from impact damage, this embodiment provides the following implementation method. Please refer to... Figure 2 or Figure 4 The end cap 320 has a flexible layer inside, which wraps around the bearing 310. The flexible layer reduces the possibility of damage to the bearing 310.
[0041] It should be noted that when users repair electronic devices using a combination of handheld tools, they often disassemble small components or screws. To facilitate the placement of these disassembled components or screws in designated locations, this embodiment provides the following implementation method. Please refer to... Figure 2 A magnet 500 and a retaining ring 600 are provided at the first end, and the magnet 500 and the retaining ring 600 are sleeved on the tool head 200; the retaining ring 600 is used to fix the magnet 500. The magnetic force of the magnet 500 can attract the disassembled components or screws to the tool head 200, making it convenient for the user to place the disassembled components or screws in a designated position.
[0042] Based on the above implementation, the fixing ring 600 fixing the magnet 500 can be implemented in various ways. This embodiment provides the following implementation. Please refer to... Figure 2 The fixing ring 600 includes a first fixing sub-ring 610 and a second fixing sub-ring 620, with the magnet 500 located between the first fixing sub-ring 610 and the second fixing sub-ring 620. The way the first fixing sub-ring 610 and the second fixing sub-ring 620 clamp the magnet 500 prevents axial movement of the magnet 500. In this embodiment, the method in which the first fixing sub-ring 610 and the second fixing sub-ring 620 are fixed relative to the tool head 200 is not limited. Preferably, the first fixing sub-ring 610 and the second fixing sub-ring 620 can be made of rubber, achieving fixation through static friction.
[0043] In summary, the present application provides a combined hand tool comprising: a handle 100 having opposing first and second ends; a tool head 200 detachably mounted to the first end; and a support head 300 rotatable relative to the handle 100 and detachably mounted to the second end. Thus, all components of the hand tool can be disassembled and assembled.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
