[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a limiting spring at the bottom of the tool handle. The limiting spring comprises a first segment, a third segment, and a second segment connecting the first and third segments, with the third segment higher than the first segment. The tool handle presses against the third segment. Because the limiting spring is elastic, it deforms under force and recovers when the force is removed. Therefore, the limiting spring hinders the rotation of the tool handle. When the tool handle is folded (0°), the limiting spring provides resistance, stabilizing the folded state. When the tool handle rotates 90°, it compresses the limiting spring, deforming it and providing greater resistance, keeping the tool handle perpendicular to the handle. This facilitates tightening screws in confined spaces and with greater force, while also preventing the tool handle from easily detaching from the handle during use. When the tool handle rotates 180°, it similarly compresses the limiting spring, stabilizing the tool handle in an unfolded state where it is aligned with the handle. Therefore, this invention, with its limiting spring, provides resistance during the folding and unfolding rotation of the tool handle, stabilizing both folded and unfolded states and maintaining the tool handle perpendicular to the handle, making it more convenient and practical to use. In addition, this utility model also provides a first cutting tool assembly and a second cutting tool assembly. The locking mechanism of the first cutting tool assembly can lock the first blade in the unfolded state. The locking mechanism of the first cutting tool assembly facilitates the replacement of the first blade and can fasten the first blade. The locking mechanism of the second cutting tool assembly can lock the second blade in the unfolded state. Moreover, the second blades of the second cutting tool assemblies provided on both sides of the handle are of different types and are suitable for different scenarios. Attached Figure Description

[0032] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] Example 1

[0034] likeFigures 1 to 7 As shown, a preferred embodiment of this utility model provides a multi-functional and multi-purpose cutting tool, including a handle 1 and a tool assembly. The tool assembly includes a tool head 2, a tool rod 3, and a limiting spring 4. The tool head 2 is connected to the first end of the tool rod 3, and the second end of the tool rod 3 is rotatably connected to the handle 1. The limiting spring 4 is connected to the handle 1, and the second end of the tool rod 3 presses against the limiting spring 4.

[0035] Handle 1 includes a first handle plate 101 and a second handle plate 102, which are arranged parallel to each other and spaced apart. Tool rod 3 and limiting spring plate 4 are disposed between the first handle plate 101 and the second handle plate 102. Tool rod 3 is rotatably connected to the first handle plate 101 and the second handle plate 102 through a first connecting shaft 5.

[0036] The limiting spring 4 is located below the tool rod 3. The limiting spring 4 includes a first segment 401, a second segment 402, and a third segment 403. The first segment 401 and the third segment 403 are located at opposite ends of the second segment 402. The first segment 401 is connected to the first handle plate 101 and the second handle plate 102. The third segment 403 is higher than the first segment 401, and the tool rod 3 presses against the third segment 403. In this embodiment, the limiting spring 4 is integrally formed.

[0037] In this embodiment, a limiting spring 4 is provided below the tool lever 3. The limiting spring 4 includes a first segment 401, a third segment 403, and a second segment 402 connecting the first segment 401 and the third segment 403. The third segment 403 is higher than the first segment 401. The tool lever 3 presses against the third segment 403. Since the limiting spring 4 is elastic, it can deform under force and recover when the force is removed. Therefore, the limiting spring 4 hinders the rotation of the tool lever 3. When the tool lever 3 is in a folded state, that is, when the tool lever 3 is at 0°, the limiting spring 4 provides resistance and stabilizes the folded state of the tool lever 3. When the tool lever 3 rotates 90°, it squeezes the limiting spring 4 to deform it, providing greater resistance and making the tool lever 3 perpendicular to the handle 1. This makes it convenient to tighten screws in a small space and screws that require greater force to tighten. At the same time, it makes it less likely for the tool lever 3 to come loose from the handle 1 during use. When the tool lever 3 rotates 180°, it also squeezes the limiting spring 4, stabilizing the tool lever 3 and the handle 1 in an unfolded state where they are in the same straight line. Therefore, the limiting spring 4 in this embodiment can provide resistance when the tool rod 3 rotates during folding and unfolding, which can not only stabilize the folded and unfolded states, but also keep the tool rod 3 perpendicular to the handle 1, making it more convenient to use and more practical.

[0038] Furthermore, in this embodiment, the first handle plate 101 is provided with an operation notch 1011, which is opposite to the tool lever 3. When the tool assembly is folded, the tool lever 3 is located between the first handle plate 101 and the second handle plate 102, and is in a horizontal state parallel to the handle 1. Therefore, by providing the operation notch 1011, the tool lever 3 can be contacted from the side to rotate it.

[0039] In addition, the first end of the tool handle 3 in this embodiment is provided with a connecting sleeve 21, and the tool head 2 is detachably inserted into the connecting sleeve 21. The two ends of the tool head 2 are different tool heads. Different tool heads 2 can achieve different functions, adapt to more application scenarios, and improve practicality. The tool head in this embodiment is a screwdriver head, and the two ends of the tool head 2 are a flathead screwdriver head and a Phillips head screwdriver head, respectively.

[0040] Furthermore, the tool head 2 in this embodiment is also provided with a locking structure, which includes a locking ball 6 and a locking spring. A locking hole is provided on the side of the tool head 2, and the locking spring is located inside the locking hole. One end of the locking spring is connected to the bottom of the locking hole, and the other end of the locking spring is connected to the locking ball 6. When the tool head 2 is inserted into the connecting sleeve 21, the locking ball 6 is secured to the inner wall of the connecting sleeve 21, preventing the tool head 2 from falling off, and the tool head 2 can be pulled out with slight force.

[0041] Example 2

[0042] The difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, the multi-functional and multi-purpose cutting tool in this embodiment also includes a first cutting tool assembly.

[0043] In this embodiment, the multi-functional and multi-purpose cutting tool further includes a first cutting tool assembly, which is disposed at the front end of the handle 1, and the tool assembly is disposed at the rear end of the handle 1.

[0044] The first cutting tool assembly includes a first cutting blade 7, a tool holder 8, and a locking mechanism. The first end of the tool holder 8 is provided with a slot 801, through which the first cutting blade 7 is detachably inserted into the tool holder 8. The other end of the tool holder 8 is rotatably connected to the handle 1 via a second connecting shaft 9.

[0045] The locking mechanism includes a fixing block 10, a slider 11, a locking spring 12, and a locking pin 13, which are sequentially mounted on the handle. The fixing block 10 is mounted on the handle 1. The slider 11 is slidably connected to the handle 1. The locking spring 12 is located between the slider 11 and the fixing block 10. One end of the locking spring 12 is connected to the fixing block 10, and the other end of the locking spring 12 is connected to the slider 11. The locking pin 13 is connected to the handle 1 and is located in front of the slider 11. The locking pin 13 is located on the rotation trajectory of the second end of the blade sheath 8. The second end of the blade sheath 8 is provided with an avoidance notch 802. When the blade sheath 8 rotates to abut against the locking pin 13, the slider 11 is located at the avoidance notch 802. At this time, the locking spring 12 is in its natural length state. When the sheath 8 is in the folded state, it is located between the first handle plate 101 and the second handle plate 102 of the handle 1. The end of the sheath 8 connected to the handle 1 rests against the slider 11, compressing the locking spring 12. After the sheath 8 rotates to the unfolded state, the end of the sheath 8 connected to the handle 1 rests against the locking pin 13, preventing the sheath 8 from rotating further. At this time, the clearance notch 802 is opposite to the slider 11, the locking spring returns to its original position, and the slider 11 moves forward. The slider 11 moves to the clearance notch 802, preventing the sheath 8 from rotating backward. Therefore, under the restriction of the locking pin 13 and the slider 11, the sheath 8 cannot rotate in either the forward or reverse direction. When folding is required, the user pushes the slider 11 backward, the slider 11 disengages from the clearance notch 802, compresses the locking spring 12, and the sheath 8 rotates to return to the folded state.

[0046] Furthermore, in this embodiment, the end of the blade sheath 8 that connects to the handle 1 is arc-shaped, which can reduce the resistance to rotation when the blade sheath 8 is unfolded.

[0047] In addition, the blade sheath 8 in this embodiment is provided with a locking mechanism, which includes a locking spring 14. The side of the blade sheath 8 has an installation notch 803 communicating with its interior. One end of the locking spring 14 is connected to the blade sheath 8, and the other end of the locking spring 14 extends to the installation notch 803. The locking spring 14 has a locking post 15, and the first blade 7 has two locking notches 701 arranged at intervals along its length. The locking spring 14 is elastic and can spring back to its original position after the external force is removed. When the first blade 7 is inserted into the blade sheath 8, the locking post 15 is located in the locking notch 701. In use, pressing the locking spring 14 causes the locking spring 14 to shift laterally, causing the locking post 15 to exit from the locking notch 701, and the first blade 7 can be pulled out from the blade sheath 8. When installing the first blade 7, press the locking spring 14 to make it shift laterally. After inserting the first blade 7 into the blade sleeve 8, release the locking spring 14. The locking spring 14 returns to its original position, causing the locking post 15 to be inserted into the locking notch 701 of the first blade 7, thereby fixing the first blade 7.

[0048] In this embodiment, the first blade 7 is a paper cutter.

[0049] In addition, the first segment 401 of the limiting spring 4 in this embodiment is provided with an outwardly protruding plug end 404, and the handle 1 is provided with a connection hole. The plug end 404 is inserted into the connection hole for connection.

[0050] The other structures in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0051] Example 3

[0052] The difference between this embodiment and embodiment two is that, based on embodiment two, the multi-functional and multi-purpose cutting tool in this embodiment also includes a second cutting tool assembly.

[0053] In this embodiment, the multi-functional and multi-purpose knife also includes a second knife assembly. The second knife assembly is provided on one or both sides of the handle 1. The second knife assembly includes a second blade 16 and a locking mechanism. The locking mechanism includes a locking spring 17. The second blade 16 is rotatably connected to the handle 1 through a third connecting shaft 18. One end of the locking spring 17 away from the rotatable connection between the second blade 16 and the handle 1 is connected to the handle 1. The other end of the locking spring 17 is movable. When the second blade 16 is in the unfolded state, the locking spring 17 and the second blade 16 are located on the same plane. The movable end of the locking spring 17 abuts against the end of the second blade 16 and can prevent the second blade 16 from rotating. When folding the second blade 16, pressing the locking spring 17 causes it to shift laterally, removing it from the rear end of the second blade 16 and allowing it to rotate. Once the second blade 16 has rotated a certain angle, it is positioned between the locking spring 17 and the handle 1, allowing it to continue rotating until folded without user pressure, thus enabling its storage. When unfolding, once the second blade 16 has rotated to its final position and the lateral pressure is released, the locking spring 17 returns to its original position, resting against the rear end of the second blade 16 to prevent further rotation. This stably maintains the unfolded state of the second blade 16 for convenient use.

[0054] The locking mechanism in this embodiment also includes a limiting pin 19, which is connected to the handle 1 and is located on the rotation path of the second blade 16. When the second blade 16 is unfolded, the limiting pin 19 prevents the second blade 16 from continuing to rotate. Therefore, if the second blade 16 rotates forward to unfold and reverses to fold, when the second blade 16 is in the fully unfolded state, the limiting pin 19 abuts against the back of the second blade 16 to prevent the second blade 16 from continuing to rotate forward, and the locking spring 17 abuts against the rear end of the second blade 16 to prevent the second blade 16 from reversing.

[0055] In addition, the second blade 16 in this embodiment is provided with a through-hole 1601. When the second blade 16 is in the folded state, the user can pull out the second blade 16 through the pull hole 1601 to easily rotate the second blade 16.

[0056] In this embodiment, the locking spring 17 is provided with a protrusion 1701, which is a spherical surface. When the second blade 16 rotates, the second blade 16 presses against the locking spring 17. By providing the protrusion 1701, the second blade 16 can press against the protrusion 1701, which can reduce the rotation area between the second blade 16 and the locking spring 17 when rotating, reduce resistance, and protect the locking spring 17 and the second blade 16.

[0057] Furthermore, a second blade assembly is provided on both sides of the handle 1. The second blade 16 of the second blade assembly on one side of the handle 1 is a machete 1602, and the second blade 16 of the second blade assembly on the other side of the handle 1 is a serrated blade 1603. The machete 1602 is suitable for chopping, slicing, cutting, and other scenarios, while the serrated blade 1603 is suitable for sawing.

[0058] In this embodiment, when the first and second cutting tool assemblies are in a folded state, the sheath 8, the first blade 7, and the second blade 16 are located on one side of the handle 1, the tool assembly and the locking mechanism are located on the other side of the handle 1, the locking spring 17 is located between the sheath 8 and the second blade 16, and the second blade 16 is located between the locking spring 17 and the first handle plate 101 or the second handle plate 102.

[0059] In this embodiment, both the first handle 101 and the second handle 102 include a main body 103 and a protective part 104. The protective part 104 is connected to the outside of the main body 103. The main body 103 is located between the protective part 104 and the locking spring 17. The main body 103 is provided with a receiving notch 105. The second blade 16 is located at the receiving notch 105. The protective part 104 is provided with a plurality of weight-reducing holes 1041.

[0060] Furthermore, the handle 1 of this embodiment is provided with a mounting clip 20. One end of the mounting clip 20 is connected to the handle 1, and the other end of the mounting clip 20 is tilted away from the handle 1. The multi-functional and multi-purpose knife of this embodiment can be clamped onto an object and fixed by the mounting clip 20.

[0061] The other structures in this embodiment are the same as in Embodiment 2, and will not be described again here.

[0062] In summary, this utility model embodiment provides a multi-functional and multi-purpose cutting tool. It features a limiting spring 4 positioned below the tool handle 3. The limiting spring 4 includes a first segment 401, a third segment 403, and a second segment 402 connecting the first segment 401 and the third segment 403. The third segment 403 is higher than the first segment 401. The tool handle 3 presses against the third segment 403. Because the limiting spring 4 is elastic, it can deform under force and recover when the force is removed. Therefore, the limiting spring 4 hinders the rotation of the tool handle 3. When the tool lever 3 is folded (0°), the limiting spring 4 provides resistance, stabilizing the folded state of the tool lever 3. When the tool lever 3 rotates 90°, it compresses the limiting spring 4, deforming it and providing greater resistance, keeping the tool lever 3 perpendicular to the handle 1. This facilitates tightening screws in confined spaces and for screws requiring greater force, while also preventing the tool lever 3 from easily detaching from the handle 1 during use. When the tool lever 3 rotates 180°, it similarly compresses the limiting spring 4, stabilizing the tool lever 3 in its unfolded state, where it is aligned with the handle 1. Therefore, this embodiment of the invention, with its limiting spring 4, provides resistance during the rotation of the tool lever 3 during folding and unfolding, stabilizing both the folded and unfolded states while maintaining the perpendicularity between the tool lever 3 and the handle 1, making it more convenient and practical to use. In addition, this utility model embodiment also provides a first cutting tool assembly and a second cutting tool assembly. The locking mechanism of the first cutting tool assembly can lock the unfolded state of the first blade 7. The locking mechanism of the first cutting tool assembly facilitates the replacement of the first blade 7 and can fasten the first blade 7. The locking mechanism of the second cutting tool assembly can lock the unfolded state of the second blade 16. The second blades 16 of the second cutting tool assemblies provided on both sides of the handle 1 are of different types and are suitable for different scenarios.

[0063] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
