One end of the lead screw 15 is movably connected to the top side of the U plate 16. The inner wall of the bone drill body 11 is movably connected to one end of the pad 17. The inner wall of the pad 17 is provided with a positioning hole 112. The inner wall of the positioning hole 112 is provided with a positioning arm 18. The inner wall of the positioning hole 112 is correspondingly engaged with one end of the positioning arm 18. One side of the positioning arm 18 is movably connected to one side of the connecting arm 13. One side of the bone drill body 11 is provided with a gear 110. One side of the bone drill body 11 is movably connected to one end of the gear 110. A rectangular frame 111 is provided on the outside of the gear 110. The outside of the gear 110 is meshed with the inner wall of the rectangular frame 111. One end of the rectangular frame 111 is connected through to the inner wall of the side plate 12. One end of the rectangular frame 111 is engaged with the inner wall of the moving block 19. One end of the U plate 16 is perpendicularly connected through to the inner wall of the pad 17.

[0022] In this embodiment, the type of arm binding electric bone drill in use, in order to be able to increase the support point of operator, therefore in the bone drill body 11 one side design has the side plate 12, the moving plate on the connecting arm 13 and the inner wall of the side plate 12 are vertically corresponding, so that the two complete connection, with the rotation of the positioning arm 18, one end into the pad 17, the pad 17 is limited, at the same time increases the support point, so that the operator will put the arm on the pad 17, can keep stable state, at this time, the screw 15 is rotated, so that the U plate 16 will move in the original position after being affected by transmission, and gradually with the arm of the operator, at the same time through the inner wall of the pad 17, and then the weight of the bone drill body 11 will not rely on the wrist support, pad 17 and U plate 16 can also share a part of the weight, which helps to reduce the hand fatigue and stress of the operator, so that the long time operation is more comfortable and sustainable, can effectively support and fix the arm of the operator, so that the arm can keep stable in the operation process.

[0023] Secondly, in order to be able to disassemble the support assembly after use, therefore, by rotating the gear 110, the inner wall of the rectangular frame 111 will gradually exit from the moving block 19 after being engaged, thereby releasing the restriction of the support assembly, reducing the occupied space when storing or storing, which is particularly important for the environment with limited space such as operating room, can optimize the space utilization, finally, the pad 17 is moved again, which is vertically combined with the inner wall of the bone drill body 11 and stored in the bone drill body 11, optimizing the storage and arrangement of the equipment.

[0024] Embodiment 2

[0025] As shown in Figures 1-4 The auxiliary mechanism 2 includes a magnet 21, the outer side of the magnet 21 is provided with a pad 17, the outer side of the magnet 21 is fixedly connected with the inner wall of the pad 17, one side of the magnet 21 is provided with a magnet 22, one side of the magnet 21 is adsorbed with one side of the magnet 22, the outer side of the magnet 22 is fixedly connected with the inner wall of the bone drill body 11.

[0026] In this embodiment, the magnet 21 is installed on the pad 17, when the pad 17 is moved, the magnet 21 will gradually produce adsorption capacity with the magnet 22 on the bone drill body 11, when the pad 17 is moved to the vertical state, the magnet 21 and the magnet 22 will be combined, and their adsorption force can ensure that the pad 17 keeps stable position after storage. This can prevent the pad 17 from moving or being damaged accidentally during storage or transportation, and can help the pad 17 to automatically align and position, ensuring that the pad 17 is reset at the correct position and angle.

[0027] Working principle:

[0028] As Figures 1-4 shown, the positioning arm 18 is rotated, one end of which enters the pad plate 17, limiting and adding support points to the pad plate 17, so that the operator can keep stable when putting the arm on the pad plate 17. At this time, the lead screw 15 is rotated, so that the U plate 16 moves in the original position after being affected by the transmission, and gradually fits the operator's arm, and penetrates the inner wall of the pad plate 17, so that the weight of the bone drill body 11 is not supported by the wrist alone, and the pad plate 17 and the U plate 16 can also share part of the weight. The gear 110 is rotated, so that the inner wall of the rectangular frame 111 gradually exits from the moving block 19 after being engaged, thereby gradually releasing the support restriction and reducing the occupied space during storage or storage, which is particularly important for limited space environments such as operating rooms.

[0029] The pad plate 17 is provided with a magnet 21, which gradually generates adsorption capacity with the magnet 22 on the bone drill body 11 during the dialing process of the pad plate 17. When the pad plate 17 is dialled to the vertical state, the magnet 21 and the magnet 22 are combined, and their adsorption force can ensure that the pad plate 17 maintains a stable position after storage. This can prevent the pad plate 17 from moving or being damaged accidentally during storage or transportation.
