An annular groove 3 is provided at the right end of the housing 1. A connecting ring 4 is rotatably provided in the annular groove 3. A connecting block 5 is fixedly connected to the right end of the connecting ring 4. An internal thread 6 is provided on the inner wall of the housing 1. A connecting pipe 7 is fixedly connected to the left side wall of the connecting block 5. A mounting block 8 is slidably connected in the connecting pipe 7. A connecting rod 9 is fixedly connected to the left side wall of the mounting block 8. A limiting ring 10 is fixedly connected to the left end of the connecting rod 9. Rotate the connecting block 5, and drive the limiting ring 10 to rotate through the connecting pipe 7 and the connecting rod 9. Through the cooperation of the external thread 11 and the internal thread 6, when the limiting ring 10 rotates, its position moves and changes within the housing 1. The connecting rod 9 slides in the connecting pipe 7 through the mounting block 8. An external thread 11 is installed on the outer wall of the limiting ring 10, and a rubber gasket 12 is installed on the inner wall of the limiting ring 10. According to the position of the needle tip of the radiofrequency thermocoagulation electrode trocar 2 within the housing 1, rotate the connecting block 5 to move the limiting ring 10 to a suitable position, so that the needle tip part of the radiofrequency thermocoagulation electrode trocar 2 is wrapped by the rubber gasket 12, which can prevent the needle tip part of the radiofrequency thermocoagulation electrode trocar 2 from colliding with the inner wall of the housing 1, and has a good limiting and protecting effect on the needle tip part.

Through the cooperation of the external thread 11 and the internal thread 6, when the limiting ring 10 rotates, its position inside the housing 1 moves and changes. The connecting rod 9 slides inside the connecting pipe 7 through the mounting block 8. According to the position of the tip of the radiofrequency thermocoagulation electrode trocar 2 inside the housing 1, the connecting block 5 is rotated to move the limiting ring 10 to a suitable position, so that the tip part of the radiofrequency thermocoagulation electrode trocar 2 is wrapped by the rubber washer 12, which can prevent the tip part of the radiofrequency thermocoagulation electrode trocar 2 from colliding with the inner wall of the housing 1, and has a good limiting and protecting effect on the tip part. It can adapt to radiofrequency thermocoagulation electrode trocars 2 of different models and lengths, so that the subsequent use effect of the radiofrequency thermocoagulation electrode trocar 2 will not be affected. When it is necessary to use the radiofrequency thermocoagulation electrode trocar 2, it is pulled outward.
