[0026] Working principle: When using the invention, put the handle 1 into the first fixed hollow tube 8 and the gear ring 9, then use the bolt 42 to rotate the gear ring 9 to slide in the first fixed hollow tube 8. When the gear ring 9 rotates, it drives the two gears 13 to rotate, and the gear 13 drives the driving column 14 to move. The driving column 14 drives the hollow block 11 to slide on the outside of the first limit rod 10, so that the hollow block 11 drives the clamping arc block 16 to move through the first connecting rod 15. When the two clamping arc blocks 16 move close to each other, the handle 1 can be clamped, and then the bolt 42 is used to cooperate with the threaded hole 43 in the gear ring 9 to fix the position of the gear ring 9, and then the U-shaped block 32 on the present invention is put on The second threaded block 35 is slidably connected to the outside of the second limiting rod 36 by rotating the reciprocating screw rod 34. The second threaded block 35 drives the first L-shaped driving plate 37 when moving. The first L-shaped driving plate 37 can push the hollow rotating plate 38 to rotate when moving. The hollow rotating plate 38 can drive the second L-shaped driving plate 39, thereby making the second L-shaped driving plate 39 drive the clamping block 40 to slide in the limiting groove 41, thereby making the clamping block 40 slide toward the inside of the U-shaped block 32 to clamp and fix the fixed rod to achieve the position fixation of the present invention. When the handle 1 needs to be extended, the two-way screw rod 28 is rotated to drive the two first threaded blocks 30 to move closer. Then, the two first rotating rods 31 connected to the first fixing plate 25 are used for limiting, and the other two first rotating rods 31 are used to push the second slider 27 to slide in the second slide groove 26. When the bidirectional screw rod 28 rotates, the third slider 29 can slide in the second slide groove 26. When the second slider 27 slides in the second slide groove 26, it can drive the first fixing rod 24, and then the handle 1 is pushed to the desired position through the first fixing rod 24. When the angle of the handle 1 needs to be adjusted, the two first positioning blocks 23 are pulled apart. When the first positioning block 23 moves, it drives the first slider 20 to slide in the first slide groove 19 through the second connecting rod 21 to compress the first slider 29. A spring 22 is provided, so that the first positioning block 23 no longer limits the rotating disk 17. After the rotating disk 17 adjusts the handle 1 to the desired angle, the first positioning block 23 is released, so that the first spring 22 applies a force to the first slider 20 to reset it. The first positioning block 23 is driven by the second connecting rod 21 to cooperate with the positioning hole 44 in the rotating disk 17 to fix the position of the rotating disk 17. When using the handle 1, the charging cable 5 is inserted into the plug-in disk to provide power. The operation control panel 2 can control the electrode blade 4 to perform ablation. The injection tube 6 can be used to inject physiological saline, and the suction tube 7 can be used to absorb waste.
