Description

Technical Field

[0001] The utility model relates to the technical field of screwdrivers, in particular to a multi-purpose combined screwdriver. Background Art

[0002] A screwdriver is a common tool used to turn screws into place. It usually has a thin wedge-shaped head that can be inserted into the slot or notch of the screw head. When the screwdriver is used to pry the paint cover, it utilizes the working principle of the lever; the greater the distance from the power point to the fulcrum, the less effort is required, so a long screwdriver is more labor-saving than a short screwdriver; when the screwdriver is used to tighten the screws, it utilizes the working principle of the wheel and axle; the larger the wheel, the less effort is required, so using a thick-handled screwdriver is more labor-saving than using a thin-handled screwdriver. Screwdrivers are used very frequently in daily life, so optimization of screwdrivers is also necessary.

[0003] For example, a multifunctional screwdriver is disclosed in the Chinese utility model patent with announcement number CN207155657U. In the above prior art, although the multifunctional screwdriver has a simple structure, its magnetic part can enhance the magnetism of the shank, improve its adsorption capacity for screws, and reduce the possibility of screws falling, and its lighting part enhances the lighting effect of the work site and improves the work efficiency of the operators. However, when working at high altitude, although the operators will bring a backpack and put all the tools that may be used into the backpack, due to the special environment of high altitude working, the operators need to hold the object with one hand to keep the body stable and reach into the backpack with the other hand to take the tool. This will not only result in the operator having to judge what the tool is by feel, but also frequently reach into the backpack because of the need to change different tools, affecting the work efficiency, increasing the time of working at high altitude, and posing certain hidden dangers to the safety of the operators. Therefore, it is necessary to design a multi-purpose combined screwdriver that can change functions according to usage needs. Utility Model Content

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A multi-purpose combined screwdriver of this embodiment includes a handle 1. One end of the handle 1 is provided with a functional component that allows the screwdriver to have different functions when in use. Both sides of the functional component are provided with a protective component that wraps and protects the functional component. One end of the functional component is provided with a head component that can replace the screwdriver head accordingly when facing different types of screws.

[0027] Combination Figure 3 and Figure 4The functional component includes a mounting plate 201 fixedly mounted on one end of the handle 1 and arranged in a "mouth" shape, and a mounting shaft 202 rotatably mounted inside the mounting plate 201. A first connecting plate 5 is rotatably sleeved on the mounting shaft 202, and a seesaw 6 capable of tilting the nail is fixedly mounted on one end of the first connecting plate 5. A second connecting plate 7 is rotatably sleeved on the mounting shaft 202, and a plurality of hexagonal fixing holes of different sizes are opened on the second connecting plate 7. A third connecting plate 8 is rotatably sleeved on the mounting shaft 202, and a blade 9 for cutting is fixedly mounted on one side of the third connecting plate 8. Tools with different functions are put into the mounting plate 201 and can be taken out for use when needed.

[0028] Combination Figure 2 The protection component includes a baffle 301 rotatably arranged on one side of the mounting plate 201, a fixing belt 302 fixedly installed on one side of the baffle 301, and a fixing ball 303 fixedly installed on one side of the mounting plate 201. A limiting hole adapted to the fixing ball 303 is opened on one side of the fixing belt 302. The two baffles 301 can wrap and protect the mounting plate 201.

[0029] Combination Figure 1 and Figure 2 A replacement slot is provided at one end of the mounting plate 201, and the cutter head assembly includes a replacement base 401 slidably arranged inside the replacement slot and a cross screw head 402 fixedly installed on one side of the replacement base 401. A connecting block 10 is fixedly installed at one end of the handle 1, and a striking block 11 is fixedly installed on one side of the connecting block 10. The striking block 11 can be simply used as a hammer.

[0030] The implementation principle of a multi-purpose combined screwdriver in the embodiment of the present application is as follows: when different tools are needed in aerial work, the fixing belt 302 on one side of the mounting plate 201 is pulled to release the fixing effect of the remaining fixing balls 303, so that the baffle 301 can be opened. After the baffle 301 is opened, the corresponding tool to be used is rotated. For example, if a nail needs to be lifted up, the first connecting plate 5 can be rotated, and the nail can be lifted up by cooperating with the rocker plate 6. When an object needs to be cut, the third connecting plate 8 can be rotated out, and the blade 9 on the third connecting plate 8 can be used to cut the object. For cutting, these tools can be replaced and added according to the working environment and frequently used tools. The prepared tools can be installed inside the mounting plate 201 using the mounting shaft 202. When a different screwdriver head is needed, the currently used screwdriver head is taken out from the replacement slot and replaced with a screwdriver head of a different model prepared in advance. This can avoid the need to carry a large number of different screwdrivers at one time and save backpack space. The striking block 11 at one end of the handle 1 can be simply used as a hammer. This setting can allow a screwdriver to have the functions of different tools, which is convenient for users to use.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
