[0045] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0046] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0047] This utility model provides a handheld cutting device suitable for cutting rings, bracelets, and other ring-shaped objects (such as keychains, steel pipes, glass bottle mouths, etc.) that are worn by the human body and cannot be removed normally.

[0048] like Figures 1 to 4 As shown, the handheld cutting device includes a handle 1, a head 2, a cutting blade 3, a guard plate 4, and an adjustment assembly 5 for adjusting the guard plate 4.

[0049] One end of the handle 1 is connected to the side of one end of the head 2, and the length direction of the handle 1 is approximately perpendicular to the length direction of the head 2.

[0050] The cutting blade 3 is located at the end of the machine head 2 away from the handle 1. The machine head 2 is equipped with a drive motor 21. The cutting blade 3 is driven by the output end of the drive motor 21, and the drive motor 21 drives the cutting blade 3 to move and cut objects.

[0051] Preferably, the cutting blade 3 is a circular cutting blade made of metal or diamond materials. Preferably, the plane of the cutting blade 3 is set perpendicular to the length direction of the machine head 2 and parallel to the handle 1, which facilitates one-handed operation and accurate and precise cutting.

[0052] Furthermore, the cutting blade 3 is detachably connected to the output end of the head 2 and the drive motor 21, allowing for the selection and replacement of cutting blades 3 made of different materials according to cutting needs, thus enhancing its applicability.

[0053] The guard plate 4 is located below the side of the cutting blade 3 and is mounted on the machine head 2 via the adjustment component 5. The adjustment component 5 allows adjustment of the position of the guard plate 4 relative to the cutting blade 3, ensuring the guard plate 4 aligns with the cutting area of ​​the cutting blade 3. In use, the guard plate 4 is embedded between the ring-shaped object being cut and the skin, fitting snugly and closely to protect the skin and prevent accidental skin injury when the cutting blade 3 cuts the ring-shaped object. The adjustment component 5 allows adjustment of the relative distance between the guard plate 4 and the cutting area of ​​the cutting blade 3 to meet the cutting needs of ring-shaped objects of different thicknesses.

[0054] Preferably, the guard plate 4 is a slender guard plate made of alloy material, i.e., a slender alloy guard plate. The end closer to the cutting blade 3 is narrower and thinner, so as to better embed itself between the skin and the object to be cut. Preferably, the bottom surface of the guard plate 4 is a concave arc surface, which can better fit the fingers, arms, and other parts of the body. The slender alloy guard plate can fit well with the cutting blade 3 and the ring-shaped object to be cut, providing a good protective effect during cutting.

[0055] In one embodiment, the adjustment assembly 5 includes an adjustment arm 51, a first adjustment connector 52, and a second adjustment connector 53.

[0056] One end of the adjusting arm 51 is fixedly installed on the end of the machine head 2 near the cutting blade 3 via a clamp or flange. The adjusting arm 51 is located between the cutting blade 3 and the handle 1, and its length direction is approximately parallel to the length direction of the handle 1.

[0057] The first adjusting connector 52 is installed on the adjusting arm 51, located on the part of the adjusting arm 51 away from the machine head 2, and can be moved and adjusted along the length of the adjusting arm 51. That is, the first adjusting connector 52 is connected to the part of the adjusting arm 51 away from the machine head 2, and can be adjusted along the adjusting arm 51.

[0058] The second adjusting connector 53 is installed on the first adjusting connector 52 and connected to the guard plate 4. The second adjusting connector 53 can adjust the guard plate 4 to rotate relative to the first adjusting connector 52, so as to move closer to or further away from the cutting part of the cutting blade 3.

[0059] In one embodiment, the adjusting arm 51 has a slot along its length. The first adjusting connector 52 includes a connecting block and a connecting bolt, the connecting bolt passing through the slot and connecting to the connecting block at the other end; by tightening the connecting bolt, the first adjusting connector 52 can be fixed to the adjusting arm 51; by loosening the connecting bolt, the first adjusting connector 52 can move along the slot on the adjusting arm 51, thereby adjusting the position of the second adjusting connector 53 and the guard plate 4 connected to it.

[0060] In one embodiment, the second adjusting connector 53 includes a first connecting block 531, a second connecting block 532, an elastic member 533, and a limiting adjusting member 534.

[0061] The first connecting block 531 is fixed to the first adjusting connecting member 52 via a fixed shaft.

[0062] One end of the second connecting block 532 is hinged to the first connecting block 531 via a fixed shaft, and the other end is connected to the first connecting block 531 via an elastic member 533. That is, when the elastic member 533 is compressed or extended, the second connecting block 532 can rotate relative to the junction of the fixed shaft. The guard plate 4 is fixedly connected to the second connecting block 532 and moves with the movement of the second connecting block 532.

[0063] The limiting adjustment component 534 is adjustablely mounted on the first connecting block 531. Adjusting the limiting adjustment component 534 can act on the second connecting block 532 to cause the elastic component 533 to deform (such as stretching or compressing), so that the guard plate 4 rotates with the second connecting block 532 to move away from or closer to the cutting blade 3, thereby realizing the adjustment of the distance between the guard plate 4 and the cutting blade 3 to adapt to ring-shaped objects of different thicknesses to be cut.

[0064] More preferably, such as Figure 4 As shown, the end of the first connecting block 531 and the second connecting block 532 connected by the elastic element 533 is the end closer to the cutting blade 3; the end of the first connecting block 531 and the second connecting block 532 hinged by the fixed shaft is the end farther away from the cutting blade 3. The elastic element 533 is a tension spring; the limiting adjustment element 534 is an adjusting bolt.

[0065] When the limiting adjustment member 534 is not acting on the second connecting block 532, the tension spring of the elastic member 533 pulls the second connecting block 532 closer to the first connecting block 531, and the guard plate 4 gets closer to the cutting blade 3. When the limiting adjustment member 534 abuts against the second connecting block 532, the tension spring can be stretched, causing the second connecting block 532 and the guard plate 4 to rotate relative to the hinge part of the fixed shaft, so that the guard plate 4 moves away from the cutting blade 3, which is convenient for accommodating thicker annular objects to be cut, and better fitting the guard plate 4 to the skin and embedding it between the annular object to be cut and the skin.

[0066] Furthermore, adjusting the limiting adjustment member 534 can achieve the preset cutting depth between the cutting blade 3 and the guard plate 4; specifically, adjusting the limiting adjustment member 534 makes the guard plate 4 and the cutting blade 3 have a certain distance, which is less than the thickness of the object to be cut (the thickness of the object to be cut minus this distance is the preset cutting depth), and the guard plate 4 is embedded between the object to be cut and the skin. At this time, the limiting adjustment member 534 does not abut against the second connecting block 532. When cutting, the spring acts as a brake to cut to the set depth (at this time, the limiting adjustment member 534 abuts against the second connecting block 532).

[0067] In one embodiment, the handheld cutting device further includes a water tank 6, which is installed between the protective plate 4 and the second connecting block 532, located at the end of the protective plate 4 away from the cutting blade 3. The water tank 6 has a water inlet and a cover at its upper part, and an automatic water outlet at its lower part near the protective plate 4. A water trough 41 extends along the length of the upper side of the protective plate 4, with one end of the trough 41 corresponding to the water outlet of the water tank 6 and the other end corresponding to the edge of the cutting blade 3. During use, cold water can be automatically released to cool the cutting area, preventing sparks or high temperatures generated during cutting from causing skin damage.

[0068] It also includes a protective cover 31, which is installed on one end of the machine head 2 near the cutting blade 3; the protective cover 31 is adapted to the cutting blade 3 and covers the upper edge of the cutting blade 3, with the cutting part located at the bottom. The protective cover 31 can effectively prevent damage caused by the operation or breakage of the cutting blade 3.

[0069] The handle 1 is preferably cylindrical in shape for easy gripping. A switch button 11 is provided on the handle 1, which is connected to the drive motor 21 to control the start or stop of the drive motor 21, thereby controlling the rotation or stop of the cutting blade 3. The position of the switch button 11 preferably corresponds to the position of the thumb when gripping, facilitating one-handed operation.

[0070] The handheld cutting device also includes a battery 12, which is connected to the drive motor 21 and provides power to the drive motor 21. Preferably, the battery 12 is a quick-connect rechargeable battery, located at the end of the handle 1, which can be replaced and recharged for repeated use. This makes the handheld cutting device more versatile, applicable to more occasions, portable, and requires no external power source.

[0071] In summary, the handheld cutting device of this application features a protective plate 4 that can be embedded between the skin and the object being cut, providing skin protection; a water tank 6 that automatically releases cooling water to cool the cutting area and prevent skin burns; a protective cover 31 that prevents injury caused by the cutting blade 3 during operation or breakage, ensuring high safety; the device has a simple structure, is compact, can be operated with one hand, is easy to use, cuts quickly, and requires no professional training; it is suitable for cutting rings, bracelets, and other ring-shaped objects worn on the body, making it highly versatile.
