[0024] Reference Figure 1-4 A protective device for a high-frequency electrosurgical pen includes a high-frequency electrosurgical pen body 1, a signal connection line 2 fixedly connected to the high-frequency electrosurgical pen body 1, a connection terminal 3 fixedly connected to the end of the signal connection line 2, a protective sleeve 4 fixedly connected to the end of the high-frequency electrosurgical pen body 1, a fixing member 5 fixedly connected to the other end of the protective sleeve 4, and a cutting head 16 connected to the fixing member 5 through a snap-fit ​​mechanism. The fixing member 5 not only serves as a connection but also undertakes the task of installing the cutting head 16. A symmetrically arranged fixing rod 15 is fixedly connected to the outer wall of the fixing member 5, and a capping mechanism is connected to the fixing rod 15.

[0025] The high-frequency electric scalpel body 1 is the main component of the device. It transmits high-frequency electrical energy to the required location through the signal connection line 2. The signal connection line 2 is used to connect the high-frequency electric scalpel to the host to ensure a stable power supply.

[0026] The snap-fit ​​mechanism includes an annular plate 8 fixedly connected to the outer wall of the cutter head 16. The outer wall of the annular plate 8 is fixedly connected to symmetrically arranged mounting blocks 9. The mounting blocks 9 are provided with elastic elements. The fixing element 5 is provided with a cavity 6. The edge of the cavity 6 is provided with symmetrical sliding grooves 7. The cavity 6 can rotate in the sliding grooves 7. The cutter head 16 rotates in the sliding grooves 7 through the mounting blocks 9 on the annular plate 8, thereby realizing installation or disassembly.

[0027] The elastic element includes a spring groove 10, which is formed on the mounting block 9. The sliding groove 7 matches and fits the mounting block 9. A telescopic rod 11 is fixedly connected to the bottom of the spring groove 10. A rigid head 13 is fixedly connected to the top of the telescopic rod 11. A spring 12 is sleeved on the outer wall of the telescopic rod 11. The two ends of the spring 12 are fixedly connected to the bottom of the rigid head 13 and the bottom of the spring groove 10, respectively.

[0028] The capping mechanism includes a protective sleeve 17, on which a first limiting groove 18 and a second limiting groove 19 are symmetrically arranged. The first limiting groove 18 and the second limiting groove 19 are connected and are arranged in an L-shape. Two plugs 20 are fixedly connected to the end of the protective sleeve 17. Two symmetrically arranged receiving cavities 14 are provided on the fixing member 5, and the receiving cavities 14 are connected to the cavity 6.

[0029] The distance between the two plugs 20 is the same as the distance between the two receiving cavities 14, the distance between the two mounting blocks 9 is the same as the distance between the two sliding grooves 7, and the distance between the two fixing rods 15 matches the distance between the two first limiting grooves 18.

[0030] The specific working principle of this utility model is as follows:

[0031] In actual operation, when this device is used, the user first installs the cutter head 16 onto the fixing member 5. The annular plate 8 fixedly connected to the cutter head 16 and the mounting block 9 on its outer side wall cooperate with the sliding groove 7 in the cavity 6 inside the fixing member 5 to achieve a snap-fit ​​fixation. The elastic element on the mounting block 9 can provide a locking mechanism. The top of the telescopic rod 11 in the spring position groove 10 is fixedly connected to a rigid head 13, and a spring 12 is provided on the outside of the telescopic rod 11. During the installation process, the mounting block 9 of the cutter head 16 slides along the sliding groove 7 to the appropriate position. The compression and return action of the spring 12 makes the rigid head 13 securely locked in the cavity 6, thereby fixing the cutter head 16.

[0032] When the cutter head 16 needs to be replaced after use, the user only needs to insert the two plugs 20 on the protective cover 17 into the receiving cavity 14, apply a certain force to make the rigid head 13 on the mounting block 9 overcome the resistance of the spring 12, and temporarily retract it into the spring position groove 10. At this time, the mounting block 9 can slide out along the slide groove 7, thereby easily disassembling the cutter head 16. This process is not only simple and quick, but also effectively prevents the cutter head 16 from being damaged due to improper operation during disassembly and assembly.

[0033] In addition, when not using the high-frequency electric knife pen, the user can screw on the protective sleeve 17 in the capping mechanism to protect the blade 16 from contamination or damage. The first limiting groove 18 and the second limiting groove 19 provided on the protective sleeve 17 are arranged in an L-shape and are connected to each other. The fixing rod 15 on the outer wall of the fixing member 5 matches the limiting groove, so that the protective sleeve 17 can rotate smoothly and be firmly fixed on the fixing member 5, thus achieving a good protective effect.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
