Detailed Implementation

[0020] To facilitate understanding of the technical solution of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1 like Figure 1-3 As shown, a modular screwdriver includes a handle 1, a mounting base 2, and a screwdriver body 3. The handle 1 is provided with a mounting groove 11, and the mounting base 2 is detachably disposed in the mounting groove 11. A limiting component is provided between the mounting groove 11 and the mounting base 2 to prevent the mounting base 2 from rotating.

[0022] like Figure 4As shown, specifically, the limiting component includes at least two limiting blocks 12 located in the mounting groove 11 and a limiting groove 24 located on the bottom surface of the mounting base 2. After the mounting base 2 is installed in the mounting groove 11, the limiting blocks 12 and the limiting groove 24 cooperate to prevent the mounting base 2 from rotating.

[0023] In one embodiment, the limiting block 12 and the limiting groove 24 are prevented from falling off the mounting base 2 from the mounting groove 11 during use by friction.

[0024] In one embodiment, the handle 1's grip portion is made of an insulating material, such as rubber; the end of the limiting block 12 may have a chamfered or rounded corner structure to facilitate installation into the limiting groove 24 of the mounting base 2, and the limiting block 12 is made of a rigid insulating material capable of withstanding a certain torque, such as hard ceramic or hard plastic. The limiting block 12 can be connected to the bottom of the mounting groove 11 by common fixing methods such as snap-fit ​​or adhesive.

[0025] like Figure 1 As shown, in one embodiment, after the mounting base 2 is installed into the mounting groove 11, at least a portion of the mounting base 2 is exposed to the outside, that is, the height of the mounting base 2 is greater than the depth of the mounting groove 11. A groove can be provided on the exposed portion of the mounting base 2. When it is necessary to disassemble the mounting base 2, a tool can be used to pry it out of the mounting groove 11. For example, the mounting base 2 has a cylindrical structure, and a groove is provided on its side. During disassembly, simply insert a tool into the groove and lift it upwards to remove the mounting base 2 from the mounting groove 11.

[0026] like Figure 5-6 As shown, the mounting base 2 is provided with a positioning groove 21, and the positioning groove 21 is provided with a first positioning part 22 and a second positioning part 23. The first positioning part 22 and the second positioning part 23 are arranged perpendicularly. The lower surface of the blade body 3 is provided with a positioning groove that matches the first positioning part 22 and the second positioning part 23. Through the cooperation of the positioning groove with the first positioning part 22 and the second positioning part 23, a certain torque can be withstood. Heat shrink tubing 4 is provided on the mounting base 2 and the blade body 3.

[0027] In one embodiment, the first positioning part 22 and the second positioning part 23 form a cross structure, and the positioning groove is a corresponding cross structure, which can prevent the blade body 3 from rotating relative to each other.

[0028] In another embodiment, the first positioning part 22 and the second positioning part 23 form a T-shaped structure, and the positioning groove is a corresponding T-shaped structure, which can prevent the blade body 3 from rotating relative to each other.

[0029] like Figure 5 , Figure 7As shown, the mounting base 2 includes a base 25 and a limiting tube 26 detachably mounted on the base 25. The surface of the base 25 is provided with a mounting ring 251, and the limiting tube 26 includes a mounting protrusion 261 and a limiting ring 262. The base 25 is recessed inward to form a cavity for accommodating the blade body 3. The cavity has a first positioning part 22 and a second positioning part 23. The diameter of the cavity is larger than the diameter of the blade body 3. The mounting protrusion 261 and the limiting ring 262 form a stepped structure. The mounting protrusion 261 is located inside the mounting ring 251, and the limiting ring 262 fits against the cylindrical surface of the blade body 3, preventing the blade body 3 from falling out of the mounting base 2 through friction.

[0030] To further prevent the blade body 3 from detaching from the mounting base 2, one end of the heat shrink tubing 4 is tightly attached to the limiting ring 262, and the other end is tightly attached to the blade body 3.

[0031] The base 25 is made of plastic, and a high-strength plastic can be selected to prevent the base 25 from breaking.

[0032] In this embodiment, the mounting base 2 and the blade body 3 can be used as modules. When the working part of the blade body 3 (i.e., the end cross structure or the straight structure) is worn and cannot be used, the mounting base 2 and the blade body 3 can be removed as a whole using tools, and then a new mounting base 2 and blade body 3 can be installed. After that, the heat shrink tubing 4 on the disassembled part can be removed, the base 25 and the limiting tube 26 can be separated, and finally the blade body 3 can be removed from the limiting tube 26.

[0033] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as part of the scope of protection of this utility model.
