the outer tube body 10 is stretched into a diseased part in a patient, the inner tube body 50 is moved forwards through threaded fit by rotating the adjusting nut 701, so that the motor 401 is pushed to enable the second elastic buckle 403 to be buckled with the second buckling groove 204, and in the process that the output shaft 402 stretches into the inserting groove 203 of the cutter head 20, the output shaft is gradually abutted against one end of the cutter blade 30 positioned in the inserting groove 203, and then the cutter blade 30 is rotated, so that the cutter blade 30 is unfolded to be in a horizontal state, and as shown in fig. 5 and 7, the connection between the motor 401 and the cutter head 20 is completed; the adjusting nut 701 is continuously rotated, so that the inner tube body 50 pushes the cutter head 20 until the first elastic buckle 201 is separated from the first buckling groove 101, the motor 401 is started at this time, the output shaft 402 can drive the cutter head 20 to rotate, the cutter blade 30 is used for cutting a patient, the adjusting nut 701 can be positively and negatively rotated in the cutting process, and the distance that the cutter head 20 is separated from the outer tube body 10 can be adjusted.
After cutting, the adjusting nut 701 is reversed, so that the cutter head 20 is retracted, the first elastic buckle 201 is buckled in the first buckling groove 101, the second elastic buckle 403 is separated from the second buckling groove 204, the blade 30 is automatically stored in a vertical state under the elastic force of the return spring 60, as shown in fig. 4 and 6, in addition, the output shaft 402 does not need to completely withdraw from the inserting groove 203, and only the second elastic buckle 403 is required to be located outside the inserting groove 203.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and implement it, and not to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
