Description

Technical Field

[0001] The utility model relates to the technical field of tools, in particular to a multifunctional tool. Background Art

[0002] In daily life, when you need to install a shelf, open a wine bottle, and take out a mobile phone card, you need to use tools such as pliers, a cross screwdriver, and a card pin. These tools are easy to be placed in a scattered manner, and are small in size and easy to lose. At the same time, these tools are often independent individuals and are not well combined.

[0003] Based on the above problems, the existing patent with publication number CN 2 0 7 3 8 7 5 7 9U discloses a multifunctional tool. The first tool head and the second tool head are movably connected in an X-shaped cross shape. The first handle and the first working component can be rotated at any angle within 0 to 360° relative to the first handle, and the second handle and the second working component can be rotated at any angle within 0 to 360° relative to the second handle, so that the needle and the nail cleaner can be used at any angle, which is flexible and convenient. When the jaws need to be used, the first handle and the second handle are unfolded to form an angle of 180° with the first tool head and the second tool head, and the first handle and the second handle are folded inward to drive the first handle and the second handle respectively, thereby opening the jaws. When idle, the first handle and the first working component can be folded outside the first tool head, and the second handle and the second working component can be folded outside the second tool head, which is convenient for carrying. The multifunctional tool integrates multiple working parts into one, making the tools easier to find.

[0004] However, when implementing the above-mentioned multifunctional tool, it was found that at least the following problems still exist: in actual use, one end of the first handle and the second handle together form a jaw for clamping objects, but the other ends of the first handle and the second handle are not effectively utilized, and are only used for hinged connection of the first working component and the second working component. During use, a long lever is formed by the first working component and the second working component to leverage force, so that it can be better clamped through the jaws of the first handle and the second handle. Therefore, the back ends of the first handle and the second handle are still not fully utilized. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: See Figures 1 to 8According to an embodiment of the utility model, a technical solution is provided: a multifunctional tool, comprising: two hinged tool heads, it should be noted that the two hinged tool heads can be cross-hinged, when cross-hinged, the two tool heads form a clamp body shape as a whole, when forming the clamp body shape, the clamp ends of the two tool heads can clamp objects, or form a blade to cut objects, and the two free ends of the tool head forming the clamp ends can be tool ends, on which a cross screwdriver, a needle, a file, a peeler, an ear spoon, a flat screwdriver, a nail cleaner, a hexagonal screwdriver head, an octagonal screwdriver head, a square screwdriver head, a star screwdriver head or a Pozidriv screwdriver head can be installed; the two hinged tool heads can also be one end of one of the tool heads hinged to the other tool head, so that it presents a T shape after rotation, that is, similar to a T-shaped screwdriver head, in this case, the tool head can have three free tool ends, and the tool end can also be installed with daily tools; After the two tool heads are rotated and brought together, they have two opposite limit surfaces 1 and a limit surface, and a twisting notch 3 is formed between the limit surface 1 and the limit surface 2, and a quick-loading tool head 4 can be inserted between the twisting notch 3, and the limit surface 1 and the limit surface 2 can limit the rotation of the quick-loading tool head 4. It should be noted that the quick-loading tool head 4 is generally a standard part, generally having a mounting end and a tool end, and the tool end is a batch head, and its mounting end is a rectangular, hexagonal, octagonal or dodecagonal column. Regardless of whether the mounting end of the quick-loading tool head 4 is one of the above-mentioned columns, it has two opposite opposite surfaces, and through the two opposite surfaces being offset against the limit surface 1 and the limit surface 2, the limit surface 1 and the limit surface 2 can limit the rotation of the mounting end of the quick-loading tool head 4, thereby driving the quick-loading tool head 4 located in the twisting notch 3 to twist the screw by rotating the two tool heads.

[0030] The multifunctional tool adopts the above structure, through the twisting notch 3 formed by rotating and closing the two tool heads, the twisting notch 3 can be inserted into the quick-loading tool head 4. When in use, the limiting surface 1 and the limiting surface 2 of the two tool heads can limit the rotation of the quick-loading tool head 4, thereby driving the quick-loading tool head 4 to complete the operation of tightening the screw, so that the two tool heads can be better utilized, increasing the practicality of the multifunctional tool, and solving the problem in the prior art that the grip ends of the first handle and the second handle are not effectively utilized.

[0031] See also Figure 1-8The two tool heads are then tightened and tightened to a desired position so that the tool head 3 is not loosened and the user does not have to tighten the tool head 3 in order to prevent the tool head 4 from being loosened and the user from having to tighten the tool head 3.

[0032] See also Figure 1-4 As a preferred embodiment, when one end of the first workpiece 5 is hinged on the second workpiece 6 and rotates to present a T shape, that is, a T-shaped screwdriver bit, the user needs to grasp the first workpiece 5 and the second workpiece 6 at the abutment point to bring them together, otherwise the hinge may be easily bent and broken during the rotation of the screwdriver bit. In this grasping process, the user needs to continuously control the quick-loading tool head 4 to prevent the quick-loading tool head 4 from falling when the screwdriver bit is inserted downward into the bolt, which makes it inconvenient for the user to use. For this reason, a magnet 8 is fixed in the first workpiece 5. After the tail end of the quick-loading tool head 4 is inserted along the twisting notch 3, the tail end of the quick-loading tool head 4 is magnetically attracted by the magnet 8, so that the user can operate with one hand after grasping the first workpiece 5 and the second workpiece 6 at the abutment point and bringing them together.

[0033] See also Figure 5-8As another preferred embodiment, when the first workpiece 5 and the second workpiece 6 are cross-hinged to form a clamp body shape as a whole, since only the limiting surface 1 and the limiting surface 2 are provided, after the quick-loading tool head 4 is inserted into the twisting notch 3, the quick-loading tool head 4 is only restricted by the two surfaces, and the quick-loading tool head 4 can still move in the direction where the limiting surface 1 and the limiting surface 2 are not in contact with each other. At this time, although the limiting surface 1 and the limiting surface 2 can still exert their limiting effect, since the quick-loading tool head 4 is movable, this results in that after the first workpiece 5 and the second workpiece 6 are rotated, the quick-loading tool head 4 will continue to move in other directions. After the first workpiece 5 and the second workpiece 6 are rotated to a certain extent, the quick-loading tool head 4 will eventually break away from the twisting notch 3, and the quick-loading tool head 4 needs to be aligned with the twisting notch 3 again, which is easy to affect the work efficiency. Therefore, a protrusion 9 is extended from the limiting surface 1 of the first workpiece 5 toward the second workpiece 6, and the protrusion 9 has a limiting surface 3 10, and the limiting surface 22 of the second workpiece 6 extends toward the second workpiece 6. The protrusion 21 1, the protrusion 11 has a limiting surface 12, and the limiting surface 10 and the limiting surface 12 can be against the quick-install tool head 4 to limit the movement of the quick-install tool head 4.

[0034] See also Figure 5-8 In the present embodiment, in order to increase the practicality of the first workpiece 5 and the second workpiece 6, the ends of the first workpiece 5 and the second workpiece 6 that are away from the twisting notch 3 are jointly formed with a jaw 13. When a clamping operation is required, the jaws 13 of the first workpiece 5 and the second workpiece 6 can be aligned with the object to be clamped, and then the ends of the first workpiece 5 and the second workpiece 6 with the twisting notch 3 are tightly grasped to perform the clamping operation. It should be noted that the outer sides of the ends of the first workpiece 5 and the second workpiece 6 with the twisting notch 3 can be hinged to other workpieces. By adding other workpieces, the arm length of the first workpiece 5 and the second workpiece 6 can be increased to make it easier to clamp.

[0035] See also Figure 5-8 In this embodiment, in order to ensure that the quick-loading tool head 4 can be abutted, the movement of the quick-loading tool head 4 is restricted so that after the two tool heads are rotated and brought together, the limiting surface 1, the limiting surface 2, the limiting surface 3 10 and the limiting surface 4 12 can all abut against the quick-loading tool head 4.

[0036] Working principle:

[0037] S1. This structure presents a T-shape after one end of the first workpiece 5 is hinged on the second workpiece 6 and rotated, that is, it is similar to a T-shaped screwdriver bit. Both free ends of the first workpiece 5 and the free end on the second workpiece 6 can be used as daily tools. When the quick-install tool head 4 is needed, the second workpiece 6 can be rotated along the hinge of the first workpiece 5. After the second workpiece 6 is rotated to a preset angle, it abuts against the limit portion 7, so that a twisting notch 3 is formed between the first workpiece 5 and the second workpiece 6. Then, the mounting end of the quick-install tool head 4 is inserted along the twisting notch 3, and the magnet 8 located in the first workpiece 5 absorbs the mounting end of the quick-install tool head 4. Finally, the user grasps the first workpiece 5 and the second workpiece 6 to drive the quick-install tool head 4 to twist the bolt.

[0038] S2. In this structure, when the first workpiece 5 and the second workpiece 6 are cross-hinged to form a clamp body as a whole, the first workpiece 5 and the second workpiece 6 have a jaw 13 at one end away from the twisting notch 3. The user can align the jaw 13 of the first workpiece 5 and the second workpiece 6 with the object to be clamped, and then hold the first workpiece 5 and the second workpiece 6 at one end with the twisting notch 3 to perform the clamping operation. When the quick-loading tool head 4 is needed, the first workpiece 5 and the second workpiece 6 are rotated along the hinge to merge the clamp ends of the first workpiece 5 and the second workpiece 6. At this time, their gripping ends are close together to form a twisting notch 3. The user can insert the installation end of the quick-loading tool head 4 along the twisting notch 3. At this time, the limit surface 1 and the limit surface 2 on the first workpiece 5 are against the quick-loading tool head 4, and the limit surface 22 and the limit surface 412 on the second workpiece 6 are against the quick-loading tool head 4, so as to limit the quick-loading tool head 4. Then, the first workpiece 5 and the second workpiece 6 are twisted, thereby driving the quick-loading tool head 4 to twist the bolt.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
