Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] See also Figure 1-5 , a radio frequency microwave needle holder, comprising a main body 1, an adaptive mechanism and a fixing mechanism, the adaptive mechanism comprising a support rod 2, a pushing frame 3, a tension spring 4, a connecting plate 6, a reverse plate 7 and a secondary adjustment mechanism, the support rod 2 is mounted on the main body 1 and is rotatably connected to the main body 1, the pushing frame 3 is mounted on the main body 1 and is slidably connected to the main body 1, the tension spring 4 is mounted inside the main body 1 and its two ends are respectively fixedly connected to the main body 1 and the connecting plate 6, the connecting plate 6 is mounted inside the main body 1 and is slidably connected to the main body 1, the reverse plate 7 is mounted on the pushing frame 3 and is rotatably connected to the pushing frame 3, the secondary adjustment mechanism comprises an adjusting rod 8, a screw 9, a sliding block 10 and a handle 11, the adjusting rod 8 is mounted at one end of the support rod 2 and is rotatably connected to the support rod 2, the screw 9 is mounted on the adjusting rod 8 and is threadedly engaged with the sliding block 10 and the support rod 2, the sliding block 10 is mounted at one end of the support rod 2 and is slidably connected to the support rod 2, and the handle 11 is arranged at one end of the screw 9.

[0032] In this embodiment, the adaptive mechanism includes a support rod 2, a push frame 3, a tension spring 4, a connecting plate 6, a reverse plate 7 and a secondary adjustment mechanism. When in use, the push frame 3 is pressed, and the push frame 3 begins to slide on the main body 1. As the push frame 3 is pressed, one end of the push frame 3 directly enters the reverse hole 20. At this time, the reverse plate 7 is squeezed, and the sliding rod 21 on the reverse plate 7 begins to slide in the first slide groove 19 in the connecting plate 6, thereby pushing the sliding plate to slide in the main body 1, pushing the tension spring 4 to stretch, and disengaging the connecting rod 18. The fixing hole 17 in the connecting block 16 on the support rod 2 is formed, and the position of the support rod 2 is adjusted at this time. After the angle of the support rod 2 is correct, the push frame 3 is released. Under the action of the tension spring 4, the connecting plate 6 is reset, and the sliding rod 21 sliding in the first slide groove 19 of the connecting plate 6 slides in the opposite direction, thereby resetting the push frame 3, and one end of the push frame 3 is also disengaged from the reverse hole 20. In this process, the spring 5 on the push frame 3 is first compressed, and then the force is exerted to push the push frame 3 out, so that the reverse plate 7 can slide smoothly in the first slide groove 19.

[0033] In this embodiment, the secondary adjustment mechanism includes an adjusting rod 8, a screw rod 9, a sliding block 10 and a handle 11. When in use, it is necessary to hold the handle 11 and then turn the handle 11. The rotation of the handle 11 causes the screw rod 9 to rotate accordingly, and since one end of the screw rod 9 is threadedly engaged with the support rod 2, the screw rod 9 as a whole rotates toward the depth of the support rod 2, and the rotating plate 22 on the screw rod 9 rotates in the rotating groove 23 of the sliding block 10, while causing the sliding block 10 to slide on the support rod 2, and the protrusion 25 on the sliding block 10 slides in the second sliding groove 27 of the support rod 2 at the same time. When the sliding block 10 slides to the fixed position, the block 24 on the sliding block 10 directly enters the card hole 26 at one end of the adjusting rod 8, thereby fixing the adjusting rod 8 and completing the secondary adjustment of the adjusting rod 8.

[0034] In this embodiment, the fixing mechanism includes a needle body 12, a placement block 13, a magnetic frame 14 and a magnet 15. At this time, the needle body 12 is installed on the placement block 13, and the angles of the support rod 2 and the adjustment rod 8 are adjusted. When all adjustments are completed, treatment is started. When the needle body 12 is treated, the needle body 12 is disassembled. First, the magnetic frame 14 is removed. The magnetic frame 14 is magnetically connected to one end of the adjustment rod 8. At this time, the magnet 15 on the magnetic frame 14 is separated from one end of the adjustment rod 8, and the magnetic frame 14 is separated from the bite plate 28 on the placement block 13, so that the placement block 13 is no longer constrained, thereby separating from one end of the adjustment rod 8 and being disassembled, completing the fixation of the placement block 13. At this time, these placement blocks 13 are taken away for disinfection.

[0035] Example 2:

[0036] To sum up, when in use, the needle body 12 is installed on the placement block 13, and the angles of the support rod 2 and the adjustment rod 8 are adjusted. First, the support rod 2 is adjusted. The support rod 2 is installed on the main body 1 and is rotatably connected to the main body 1. At this time, the push frame 3 is pressed, and the push frame 3 begins to slide on the main body 1. As the push frame 3 is pressed, one end of the push frame 3 directly enters the reverse hole 20. At this time, the reverse plate 7 is squeezed, and the sliding rod 21 on the reverse plate 7 begins to slide in the first slide groove 19 in the connecting plate 6, thereby pushing the sliding plate to slide in the main body 1, pushing the tension spring 4 to stretch, and connecting The connecting rod 18 is disengaged from the fixing hole 17 in the connecting block 16 on the support rod 2, and the position of the support rod 2 is adjusted at this time. After the angle of the support rod 2 is correct, the push frame 3 is released. Under the action of the tension spring 4, the connecting plate 6 is reset, and the sliding rod 21 sliding in the first slide groove 19 of the connecting plate 6 slides in the opposite direction, thereby resetting the push frame 3, and one end of the push frame 3 is also disengaged from the reverse hole 20. In this process, the spring 5 on the push frame 3 is first compressed, and then the force is exerted to push the push frame 3 out, so that the reverse plate 7 can slide smoothly in the first slide groove 19. When the support rod 2 is adjusted, the adjustment is completed. To adjust the angle of the adjustment rod 8, you need to hold the handle 11 and then turn the handle 11. The rotation of the handle 11 causes the screw 9 to rotate accordingly, and since one end of the screw 9 is threadedly engaged with the support rod 2, the screw 9 as a whole rotates toward the depth of the support rod 2, and the rotating plate 22 on the screw 9 rotates in the rotating groove 23 of the sliding block 10, while causing the sliding block 10 to slide on the support rod 2, and the protrusion 25 on the sliding block 10 slides in the second sliding groove 27 of the support rod 2 at the same time. When the sliding block 10 slides to a fixed position, the block 24 on the sliding block 10 at this time directly enters the card hole 26 at one end of the adjustment rod 8. , thereby fixing the adjusting rod 8 and completing the secondary adjustment of the adjusting rod 8. When all adjustments are completed, the treatment begins at this time. When the needle body 12 is treated, the needle body 12 begins to be disassembled. First, remove the magnetic bracket 14. The magnetic bracket 14 is magnetically connected to one end of the adjusting rod 8. At this time, the magnet 15 on the magnetic bracket 14 is separated from one end of the adjusting rod 8, and the magnetic bracket 14 is separated from the bite plate 28 on the placement block 13, so that the placement block 13 is no longer bound, thereby separating from one end of the adjusting rod 8 and being disassembled, completing the fixation of the placement block 13. At this time, these placement blocks 13 are taken for disinfection.
