[0027] See also Figure 1 and Figure 2 The modular hand tool 10 also includes a first assembly 301, a second assembly 303, and a second tool head 300, such as a hammer head having a striking surface 330. The hammer head 300 has a third assembly portion 302. The first assembly 301 has a first upper assembly portion 311, a first lower assembly portion 312, and a first intermediate portion 310. The second assembly 303 has a second upper assembly portion 313, a second lower assembly portion 314, and a second intermediate portion 315.
[0028] The first lower assembly part 312 and the second lower assembly part 314 are respectively provided with mating assembly holes 3120 and 3140 corresponding to the plurality of assembly holes 2120, and a plurality of screws, such as Figure 1 , 2The three screws 50-1 pass through the plurality of assembly holes 2120, the first lower assembly part and the second lower assembly part respectively, and are fixed by the plurality of nuts 50-2, so as to clamp and fix the axe head 200 between the first lower assembly part 312 and the second lower assembly part 314.
[0029] The first upper assembly part 311, the third assembly part 302 and the second upper assembly part 313 are respectively provided with a plurality of assembly holes 3110, 3020, 3130 corresponding to each other, and a plurality of additional screws, such as Figure 1 、 2 The two screws 30-1 pass through the plurality of assembly holes 3110, 3020, 3130 respectively provided on the first upper assembly part 311, the third assembly part 302 and the second upper assembly part 313, and are fixed by the plurality of nuts 30-2, so as to clamp and fix the third assembly part 302 between the first upper assembly part 311 and the second upper assembly part 313.
[0030] The thickness of the third assembly part 302 can be substantially the same as that of the second assembly part 212 of the axe head 200, and is preferably made of elastic material. The term "substantially" means that the difference between the thickness of the third assembly part 302 and the thickness of the second assembly part 212 is within ±5%.
[0031] At this time, the first intermediate part 310 and the second intermediate part 315 are located in the recess 110 and clamp the recess therebetween. The first intermediate part 310 and the second intermediate part 315 can be arc-shaped structures conforming to the recess (see, for example, a part 110 of the recess, and the remaining part is not shown).
[0032] In the above connection manner, the axe head 200 is firmly connected to the tool handle 100, and the hammer head 300 is also firmly connected to the tool handle 100.
[0033] The tool handle 100 can be an integral structure, such as but not limited to being integrally formed by injection molding of engineering plastic, and can also be a wooden handle, a glass fiber handle or a nylon handle.
[0034] The tool handle 100 is preferably a curved handle, so as to be more comfortable to use.
[0035] The tool handle 100 can also be a combined axe handle. As shown in Figure 2 The tool handle 100 is combined and fixed by the intermediate metal reinforced handle 102 and the plastic conforming parts, i.e. the first plastic conforming part 101 and the second plastic conforming part 103, on both sides thereof through a plurality of screws 20-1 and nut parts 20-2.
[0036] As shown in Figure 2As shown, the first plastic conforming part 101, the intermediate metal reinforced handle 102 and the second plastic conforming part 103 are respectively provided with corresponding assembly holes 1012, 1022 and 1032, and the screw 20-1 is sequentially inserted through the assembly holes and then fastened and fixed by the screw cap 20-2. The above assembly holes can be multiple groups, such as Figure 2 six groups as shown in the middle.
[0037] In order to facilitate the suspension of the axe in the utility model, the rear end of the intermediate metal reinforced handle 102 is further provided with a suspension hole 1025.
[0038] In order to facilitate positioning and improve the firmness of assembly, the front end of the intermediate metal reinforced handle 102 is respectively provided with a first protruding part 1021 for hooking the convex rib 111 and a second protruding part 1023 for hooking the convex rib 131.
[0039] As shown in Figure 2 , and referring to Figure 1 , the corresponding positions of the first intermediate part 310, the recessed part 110, the intermediate metal reinforced handle 102 and the second intermediate part 315 are provided with positioning holes 60-1, 60-2, 60-3 and 60-4, and the positioning columns 60 are installed in the positioning holes (see Figure 1 ). The positioning columns 60 not only play a positioning role, but also can further prevent the axe from falling off. The material of the positioning columns 60 is not limited to metal material, but can also be plastic material. In the case of the positioning hole and the positioning column, the first protruding part 1021 and the second protruding part 1023 at the front end of the intermediate metal reinforced handle 102 can also be omitted.
[0040] Although not shown, for the tool handle of an integral structure, such as a whole injection handle, the two sides of the injection handle can be respectively provided with outwardly extending positioning columns, and the first intermediate part and the second intermediate part are respectively provided with positioning holes matched with the positioning columns.
[0041] As Figure 1 , Figure 2 the assembled hand tool in the utility model can also not be provided with the above positioning holes and positioning columns, and the purpose of the utility model can also be achieved. Referring to Figure 3 .
[0042] In the utility model, the term "conformity" means that the shapes of the contact parts of two components are adapted to each other, so as to ensure that the two components are closely attached.
[0043] Based on the description of the preferred embodiments of the utility model, it should be clear that the utility model defined by the appended claims is not limited to the specific details described in the above specification, and many obvious changes to the utility model without departing from the purpose or scope of the utility model can also achieve the purpose of the utility model.
