[0026] The output end of the transmission box 401 is fixedly connected with a transmission gear 402, and the upper side wall of the clamping base 5 is internally rotatably connected to a rotating inner screw sleeve 502. The internal thread of the rotating inner screw sleeve 502 is connected with three clamping segments 6. The upper side wall of the rotating inner screw sleeve 502 is fixedly connected with a driven gear 204. The driven gear 204 is meshed with the transmission gear 402, and the driven gear 204 can be driven to rotate by the transmission gear 402. A driving motor 4 is installed on the upper side wall of the transmission box 401. The output end of the driving motor 4 is matched with the input end of the transmission box 401. The driving motor 4 drives the transmission gear 402 to rotate through the transmission box 401. The three clamping segments 6 are evenly distributed about the inner support rod 501, thereby improving the stability of the clamping of the clamping segments 6.

[0027] The upper side wall of the driven gear 204 is fixedly connected with a detection sleeve 2, and a limiting inner cavity 201 is arranged inside the detection. The inner side wall of the limiting inner cavity 201 is fixedly connected with a power-on coil 202 and an induction coil 203. The power-on coil 202 and the induction coil 203 are both connected to the main controller 3. The main controller 202 can generate an alternating current in the power-on coil 202, thereby generating an alternating magnetic field. At this time, an alternating induced current will be generated in the induction coil 203.

[0029] Working principle: When the device clamps the drill rod, first, the lower end of the drill rod is passed through the limiting inner cavity, and the inner support rod 501 supports the bottom of the drill rod. The main controller 202 generates an alternating current in the energized coil 202, thereby generating an alternating magnetic field. At this time, an induced current is generated in the induction coil 203. When the drill rod passes through, the alternating magnetic field changes, thereby causing the induced current to change in size. The main controller 3 controls the drive motor 4 to work. The drive motor 4 can drive the transmission gear 402 to rotate through the transmission box 401. The transmission gear 402 can drive the rotating inner screw sleeve 502 to rotate through the driven gear 204, thereby causing the three clamping segments 6 to move upward, and then automatically clamp the drill rod, thereby effectively improving the clamping accuracy, clamping stability and clamping efficiency of the drill rod.
