When the operator uses the fixed sleeve 200, the operator holds the handle 100 and then starts the drive motor 204, which will cause the rotating shaft 205 to rotate, and then the rotating shaft 205 drives the cross rotating plate 206 to rotate. When the cross rotating plate 206 rotates, the rotating drum 201 is driven to rotate, and then the rotating drum 201 drives the circular limit block 208 to rotate inside the slide groove 207. , and at the same time, the push rod 300 will rotate. When the push rod 300 rotates, it will drive the L-shaped tooth plate 302 to slide inside the movable groove 301, and then the L-shaped tooth plate 302 will drive the gear 305 to rotate, thereby causing the rotating shaft 303 to rotate in the inner wall of the front jaw 101, so that the rotating shaft 303 drives the rear jaw 304 to flip, and then the protrusion 306 will contact the bone. Through the cooperation of the protrusion 306 and the groove 307, the bone can be removed. After use, the operator needs to When cleaning the front jaw 101, the operator rotates the bolt 102, and then the operator pulls out the front jaw 101 as a whole. At this time, the cross rotating plate 206 will be disengaged from the inside of the cross groove 202. At this time, the triangular fixing block 401 will be affected by the elastic force of the reset spring 403, and the reset spring 403 will push the triangular fixing block 401 to move inside the moving groove 400 until the triangular fixing block 401 moves to the inside of the cross groove 202, which can fix the rotating drum 201.

[0024] Furthermore, a cross groove 202 is provided in the inner wall of one end of the rotating drum 201. The cross groove 202 is in a cross shape, which is compatible with the subsequent driving device, making the rotating drum 201 more stable.

[0025] Furthermore, a protective shell 203 is fixedly installed on the top of the handle 100, and a drive motor 204 is fixedly installed on the top of the handle 100. The drive motor 204 is located inside the protective shell 203. A rotating shaft 205 is fixedly installed on the output end of the drive motor 204. Starting the drive motor 204 will cause the rotating shaft 205 to rotate. The protective shell 203 can protect the drive motor 204.

[0026] Furthermore, a cross rotating plate 206 is fixedly installed on the outer side of the rotating shaft 205. The cross rotating plate 206 is located inside the cross groove 202. The cross rotating plate 206 is adapted to the cross groove 202. The cross rotating plate 206 is movably connected to the cross groove 202. When the rotating shaft 205 rotates, the cross rotating plate 206 will rotate inside the cross groove 202, thereby driving the rotating drum 201 to rotate inside the fixed sleeve 200.

[0027] Furthermore, a slide groove 207 is opened in the inner wall of the fixed sleeve 200, and a circular limit block 208 is rotatably installed inside the slide groove 207. When the rotating drum 201 rotates, the circular limit block 208 will be driven to rotate inside the slide groove 207. The slide groove 207 and the circular limit block 208 limit the movement direction of the rotating drum 201.

[0028] Furthermore, a movable groove 301 is provided at the end of the front jaw 101 away from the handle 100, and a rotating shaft 303 is rotatably installed in the inner wall of the end of the front jaw 101 away from the handle 100, a gear 305 is fixedly installed on the outer side of one end of the rotating shaft 303, and a rear jaw 304 is fixedly installed on the outer side of the rotating shaft 303, the rear jaw 304 is located inside the movable groove 301, and a protrusion 306 is fixedly installed on one side of the rear jaw 304, and the protrusion 306 is adapted to the groove 307. When the gear 305 rotates, it will synchronously drive the rotating shaft 303 to rotate in the inner wall of the front jaw 101, and then the rear jaw 304 drives the protrusion 306 to flip, and the protrusion 306 will contact the bone. Through the cooperation of the protrusion 306 and the groove 307, the bone can be removed.

[0029] Furthermore, an L-shaped tooth plate 302 is fixedly installed on the outer side of one end of the push rod 300, and one side of the L-shaped tooth plate 302 is meshed with the gear 305. The L-shaped tooth plate 302 is located inside the movable groove 301. When the push rod 300 moves, it will drive the L-shaped tooth plate 302 to slide inside the movable groove 301, thereby causing the L-shaped tooth plate 302 to drive the gear 305 to rotate.

[0030] Furthermore, a triangular fixed block 401 is movably installed inside the moving groove 400, a limiting rod 402 is fixedly installed on the top of the triangular fixed block 401, and a return spring 403 is fixedly installed on the top of the moving groove 400. One end of the return spring 403 away from the triangular fixed block 401 is fixedly connected to the inner wall of the fixed sleeve 200, and the return spring 403 is located on the outside of the limiting rod 402. When the cross rotating plate 206 is disengaged from the inside of the cross groove 202, the elastic force of the return spring 403 will push the triangular fixed block 401 to move inside the moving groove 400 until the triangular fixed block 401 moves into the inside of the cross groove 202.

[0031] Working principle of this utility model:

[0032] When the operator uses it, the operator holds the handle 100 and then starts the drive motor 204, which will cause the rotating shaft 205 to rotate, and then the rotating shaft 205 drives the cross rotating plate 206 to rotate. Since the cross rotating plate 206 is adapted to the cross groove 202, the rotation of the cross rotating plate 206 will drive the rotating cylinder 201 to rotate, and then the rotating cylinder 201 drives the circular limit block 208 to rotate inside the sliding groove 207, and at the same time, the push rod 300 will rotate. When the push rod 300 rotates, it will drive the L-shaped tooth plate 302 to slide inside the movable groove 301, and the movable groove 301 will limit the movement direction of the L-shaped tooth plate 302. Then the L-shaped tooth plate 302 will drive the gear 305 to rotate, so that the rotating shaft 303 rotates on the inner wall of the front jaw 101. The rear jaw 304 is moved, so that the rotating shaft 303 drives the rear jaw 304 to flip, and then the protrusion 306 will contact the bone, and the bone can be removed through the cooperation of the protrusion 306 and the groove 307. When the operator needs to clean the front jaw 101 after use, the operator rotates the bolt 102 to release the fixing effect on the front jaw 101 and the handle 100, and then the operator pulls the front jaw 101 outward as a whole. At this time, the cross rotating plate 206 will be disengaged from the inside of the cross groove 202. At this time, the triangular fixing block 401 will be affected by the elastic force of the reset spring 403, and the reset spring 403 will push the triangular fixing block 401 to move in the inside of the moving groove 400 until the triangular fixing block 401 moves to the inside of the cross groove 202, which can fix the rotating cylinder 201.
