The extrusion rod 22 is provided with an extrusion groove 23, and a torsion spring 24 is fixedly connected to the position of the clamping jaw 2 corresponding to the extrusion rod 22.
[0018] The first spring 7 is located inside the lifting rod 5, and the bottom end of the first spring 7 is fixedly connected to the top end of the abutting rod 6. The first spring 7 is convenient for lifting the extrusion force of the abutting rod 6. The passage groove 9 and the slide groove 4 are in a communicating state. One end of the connected plate 10 slides through the passage groove 9 and is fixedly connected to the lifting rod 5. When the connected plate 10 moves, it is convenient to drive the lifting rod 5 to move. The active rack 11 is fixedly connected with the linkage plate 25. The bottom end of the electric telescopic rod 8 is fixedly connected with the top of the linkage plate 25. The active rack 11 is meshed with the two driven gears 13. The active rack 11 is convenient for driving the driven gear 13 to rotate, and the electric telescopic rod 8 is convenient for driving the linkage plate 25 to move up and down.

[0019] When in use, the grabbing device can be connected to an external power device. When the mechanical shaft needs to be grabbed, the electric telescopic rod 8 can be started. When the output end of the electric telescopic rod 8 is retracted, the interlocking plate 25 and the active rack 11 will be driven to move upward together. The active rack 11 will also drive the connected plate 10 to move upward together inside the passage groove 9. The upward movement of the connected plate 10 will also drive the lifting rod 5 to move upward inside the slide groove 4. The lifting rod 5 will drive the abutment rod 6 to move together through the two first springs 7. When the active rack 11 moves upward, it will drive the two driven gears 13 to rotate together. The driven gears 13 will drive the rotating rod 12 to rotate, and the rotating rod 12 will The limit block 14 and the limit groove 18 drive the clamping block 17 to rotate together, and the clamping block 17 will drive the clamping jaws 2 to rotate.

At this time, the extrusion rod 22 will be compressed and the round rod 21 will be rotated together. At the same time, the rotation of the extrusion rod 22 will also rotate and twist the torsion spring 24. When the extrusion rod 22 rotates, the extrusion groove 23 will be pressed against the compressed rod 19 is extruded, the compressed rod 19 will move in the direction of rotation of the extrusion rod 22, and the compressed rod 19 will drive the clamping block 17 to move together. At this time, each clamping block 17 will move in the direction away from the rotating rod 12, and the moving clamping block 17 will separate the limiting groove 18 from the limiting block 14. During the movement of the clamping block 17, the movable plate 16 will also be driven to slide inside the mounting groove 15. The sliding of the movable plate 16 is guided by the guide rod 26.
